Strong constraints on the rare decays Bs -> mu+ mu- and B0 -> mu+ mu-  

E-Print Network (OSTI)

A search for Bs -> mu+ mu- and B0 -> mu+ mu- decays is performed using 1.0 fb^-1 of pp collision data collected at \\sqrt{s}=7 TeV with the LHCb experiment at the Large Hadron Collider. For both decays the number of observed events is consistent with expectation from background and Standard Model signal predictions. Upper limits on the branching fractions are determined to be BR(Bs -> mu+ mu-) mu+ mu-) < 1.0 (0.81) x 10^-9 at 95% (90%) confidence level.

b -> s mu+ mu- and b -> mu+ mu- At the LHC  

E-Print Network (OSTI)

With their 2010-2011 data set, the LHC experiments have started their quest to observe the rare decays B0_{s/d} -> mu+ mu-. This study will provide very sensitive probes of New Physics (NP) effects. NP discovery potential lies as well in the study of the decay B0_d -> K*0 mu+ mu-. Results and perspectives are presented for studies at the LHC of rare B decays involving flavor changing neutral currents.

A muon that does not follow the traditional weak- force decay pattern into a lighter electron and two neutrinos, but converts wholly into an electron. WHAT WILL THIS TELL US ABOUT THE WORLD? * Observing Mu2e conversion would point the way to a unification of all the forces of nature controlling the interactions of matter. This unification of the four existing forces we observe today - gravity, the electromagnetic force, and the weak and strong forces - is considered Albert Einstein's dream of "grand unification. * Finding signs of this "grand unification" could explain how the universe evolved from being

From a {nu} factory to {mu} super + mu super {minus} Colliders  

SciTech Connect

An important feature of a {mu}-storage ring {nu}-source is that it can be extended to the possibility of a future high-energy muon collider. The neutrino source provides a useful physics device that initiates key technologies required for future {mu}{sup +}-{mu}{sup {minus}} Colliders, but with much less demanding parameter requirements. These technologies include high-intensity {mu}-production, {mu}-capture, {mu}-cooling, {mu}-acceleration and multiturn {mu} storage rings. {mu}{sup +}-{mu}{sup {minus}} colliders require a similar number of muons, but they require that the muons be cooled to a much smaller phase space and formed into a small number of bunches, and both positive and negative bunches must be simultaneously captured. These differences are discussed, and the extension of the {nu}-source to {mu}{sup +}-{mu}{sup {minus}} collider specifications is described.

Search for $B_s \\to \\mu^+\\mu^-$ and $B_d \\to \\mu^+\\mu^-$ Decays with CDF II  

SciTech Connect

A search has been performed for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} decays using 7 fb{sup -1} of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. The observed number of B{sup 0} candidates is consistent with background-only expectations and yields an upper limit on the branching fraction of {Beta}(B{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 6.0 x 10{sup -9} at 95% confidence level. We observe an excess of B{sub s}{sup 0} candidates. The probability that the background processes alone could produce such an excess or larger is 0.27%. The probability that the combination of background and the expected standard model rate of B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} could produce such an excess or larger is 1.9%. These data are used to determine {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}) = (1.8{sub -0.9}{sup +1.1}) x 10{sup -8} and provide an upper limit of {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 4.0 x 10{sup -8} at 95% confidence level.

We reconstruct the rare decays B{sup +} {yields} K{sup +} {mu}{sup +}{mu}{sup -}, B{sup 0} {yields} K*(892){sup 0} {mu}{sup +}{mu}{sup -}, and B{sub s}{sup 0} {yields} {phi}(1020){mu}{sup +}{mu}{sup -} in a data sample corresponding to 4.4 fb{sup -1} collected in p{bar p} collisions at {radical}s = 1.96 TeV by the CDF II detector at the Fermilab Tevatron Collider. Using 120 {+-} 16 B{sup +} {yields} K{sup +} {mu}{sup +}{mu}{sup -} and 101 {+-} 12 B{sup 0} {yields} K*{sup 0} {mu}{sup +}{mu}{sup -} decays we report the branching ratios. In addition, we report the measurement of the differential branching ratio and the muon forward-backward asymmetry in the B{sup +} and B{sup 0} decay modes, and the K*{sup 0} longitudinal polarization in the B{sup 0} decay mode with respect to the squared dimuon mass. These are consistent with the theoretical prediction from the standard model, and most recent determinations from other experiments and of comparable accuracy. We also report the first observation of the B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -} decay and measure its branching ratio {Beta}(B{sub s}{sup 0} {yields} {phi}{mu}{sup +}{mu}{sup -}) = [1.44 {+-} 0.33 {+-} 0.46] x 10{sup -6} using 27 {+-} 6 signal events.

Updated Search for $B_s \\to \\mu^+$ mu- at CDF  

SciTech Connect

The decay B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} is very sensitive to contributions from new physics processes. Thus the Tevatron and LHC experiments are hunting for an observation of a B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} signal. In this article the updated search for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} by the CDF experiment is presented. The CDF result was received with great interest because an excess over the background expectation is seen, although of modest statistical significance and still consistent with the prediction of a standard model signal and other experimental results.

The next generation of $\\mu\\ -> e \\gamma$ and $\\mu\\ -> 3e$ CLFV search experiments  

E-Print Network (OSTI)

We explore the possibilities for extending the sensitivity of current searches for the charged lepton flavor violating decays $\\mu\\ -> e \\gamma$ and $\\mu\\ -> eee$. A future facility such as Project X at Fermilab could provide a much more intense stopping $\\mu^+$ beam, facilitating more sensitive searches, but improved detectors will be required as well. Current searches are limited by accidental and physics backgrounds, as well as by the total number of stopped muons. One of the limiting factors in current detectors for $\\mu\\ -> e \\gamma$ searches is the photon energy resolution of the calorimeter. We present a new fast Monte Carlo simulation of a conceptual design of a new experimental concept that detects converted $e^+e^-$ pairs from signal photons, taking advantage of the improved energy resolution of a pair spectrometer based on a silicon charged particle tracker. We also study a related detector design for a next generation $\\mu\\to eee$ search experiment.

CP violation of Extended Higgs sector and Its impact on D^0 -> mu^+ mu^- decay  

E-Print Network (OSTI)

We study the impact of the CP violation of the extra Higgs sector on $D^0$ decay. The CP even and CP odd neutral Higgs mixing of the two Higgs doublet model is studied and we show how the CP violating effect of the mixing may lead to the longitudinal muon polarization asymmetry of $D^0 \\to \\mu^+ \\mu^-$. The asymmetry of the short-distance contribution is sensitive to the CP violating phase of the extended Higgs sector.

Channeling of positrons from. mu. /sup +/ decay  

SciTech Connect

The first attempt to observe the steering or channeling effect of a host crystal lattice on the trajectories of decay positrons from interstitial positive muons is described. An enhanced (flux peaking) or diminished (blocking) positron counting rate for emission along a low index crystalline axis would be evidence of such an effect and would help to determine the lattice location of the emitting muon. The expected angular widths of these features is approximately 0.2/sup 0/. A 29.8 MeV/c surface ..mu../sup +/ beam was stopped in a high quality silicon crystal wafer which was elastically bent to a good approximation to a spherical cap. This brought the (100) axes, which were initially normal to the wafer surface, to a focus at the radius of curvature R = 110 cm. The normalized e/sup +/ rate was measured as a function of position with a small two-counter scintillation telescope which was moved through the focus. We found no evidence for channeling at the 17% level, suggesting that the ..mu../sup +/ in Si either (1) makes large vibratory excursions, (2) occupies a site of low symmetry, or (3) occupies one of several possible inequivalent stopping sites.

Search for the Decay Modes D0 to e+ e-, D0 to mu+ mu-, and D0 to e+/- mu+/-  

SciTech Connect

We present searches for the rare decay modes D{sup 0} {yields} e{sup +}e{sup -}, D{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}} in continuum e{sup +}e{sup -} {yields} c{bar c} events recorded by the BABAR detector in a data sample that corresponds to an integrated luminosity of 468 fb{sup -1}. These decays are highly GIM suppressed but may be enhanced in several extensions of the Standard Model. Our observed event yields are consistent with the expected backgrounds. An excess is seen in the D{sup 0} {yields} {mu}{sup +}{mu}{sup -} channel, although the observed yield is consistent with an upward background fluctuation at the 5% level. Using the Feldman-Cousins method, we set the following 90% confidence level intervals on the branching fractions: {Beta}(D{sup 0} {yields} e{sup +}e{sup -}) < 1.7 x 10{sup -7}, {Beta}(D{sup 0} {yields} {mu}{sup +}{mu}{sup -}) within [0.6, 8.1] x 10{sup -7}, and {Beta}(D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}) < 3.3 x 10{sup -7}.

Lepton flavor violating processes \\tau ->\\mu\\gamma$, $\\tau-> 3\\mu$ and $Z-> \\mu\\tau$ in the Supersymmetric economical 3-3-1 model  

E-Print Network (OSTI)

In this work, we study the charged lepton flavor violating (cLFV) decays $\\tau-> \\mu\\gamma$, $\\tau-> 3\\mu$ and $Z->\\mu\\tau$ in the framework of the Supersymmetric economical 3-3-1 model. Analytic formulas for branching ratios (BR) of these decays are presented. We assume that there exist lepton flavor violation (LFV) sources in both right- and left-handed slepton sectors. This leads to the strong enhancement of cLFV decay rates. We also show that the effects of the LFV source to the cLFV decay rates in the left-handed slepton sector are greater than those in the right- handed slepton sector. By numerical investigation, we show that the model under consideration contains the relative light mass spectrum of sleptons which satisfies the current experimental bounds on LFV processes in the limit of small $\\tan \\gamma$. The interplay between monopole and dipole operators also was studied.

Solenoid magnet system for the Fermilab Mu2e experiment  

The Fermilab Mu2e experiment seeks to measure the rare process of direct muon to electron conversion in the field of a nucleus. Key to the design of the experiment is a system of three superconducting solenoids; a muon production solenoid (PS) which is a 1.8 m aperture axially graded solenoid with a peak field of 5 T used to focus secondary pions and muons from a production target located in the solenoid aperture; an 'S shaped' transport solenoid (TS) which selects and transports the subsequent muons towards a stopping target; a detector solenoid (DS) which is an axially graded solenoid at the upstream end to focus transported muons to a stopping target, and a spectrometer solenoid at the downstream end to accurately measure the momentum of the outgoing conversion elections. The magnetic field requirements, the significant magnetic coupling between the solenoids, the curved muon transport geometry and the large beam induced energy deposition into the superconducting coils pose significant challenges to the magnetic, mechanical, and thermal design of this system. In this paper a conceptual design for the magnetic system which meets the Mu2e experiment requirements is presented.

$\\mu$-$\\tau$ reflection symmetry and radiative corrections  

E-Print Network (OSTI)

The $\\mu$-$\\tau$ reflection symmetry is compatible with current neutrino oscillation data and easily realized under family symmetries. We prove that this symmetry preserves $\\theta_{23}=45^\\circ$, $\\delta=\\pm90^\\circ$, $\\rho,\\sigma=0,90^\\circ$, and can be embedded into the seesaw mechanism. The $\\mu$-$\\tau$ reflection symmetry preserved at a high energy scale $\\Lambda_\\text{FS}$ will be broken by radiative corrections and result in deviations of $\\theta_{23}$ from $45^\\circ$ and $\\delta$ from $\\pm90^\\circ$ at the electroweak scale. We develop an analytical method to derive the corrections to all the mixing parameters. We perform a numerical analysis in the MSSM for $\\delta=-90^\\circ$ at $\\Lambda_\\text{FS}$, and observe that $\\theta_{23}>45^\\circ$ in the normal mass ordering, $\\theta_{23}<45^\\circ$ in the inverted mass ordering, and the sizable correction to $\\delta$ prefers a negative sign. These deviations have definite directions and can be tested in the future neutrino oscillation experiments.

Analysis of D+ to K- pi+ e+ nu_e and D+ to K- pi+ mu+ nu_mu Semileptonic Decays  

E-Print Network (OSTI)

Using a large sample (~11800 events) of D^+ into K^- pi^+ e^+ nu_e and D^+ into K^- pi^+ mu^+ nu_mu decays collected by the CLEO-c detector running at the psi(3770), we measure the helicity basis form factors free from the assumptions of spectroscopic pole dominance and provide new, accurate measurements of the absolute branching fractions for D^+ into K^- pi^+ e^+ nu_e and D^+ into K^- pi^+ mu^+ nu_mu decays. We find branching fractions which are consistent with previous world averages. Our measured helicity basis form factors are consistent with the spectroscopic pole dominance predictions for the three main helicity basis form factors describing D^+ into anti-K*0 ell^+ nu_mu decay. The ability to analyze D^+ into K^- pi^+ mu^+ nu_mu allows us to make the first non-parametric measurements of the mass-suppressed form factor. Our result is inconsistent with existing Lattice QCD calculations. Finally, we measure the form factor that controls non-resonant s-wave interference with the D^+ into anti-K*0 ell^+ nu_mu amplitude and search for evidence of possible additional non-resonant d-wave or f-wave interference with the anti-K*0.

Large forward-backward asymmetry in B{yields}K{mu}{sup +}{mu}{sup -} from new physics tensor operators  

SciTech Connect

We study the constraints on possible new physics contributions to the forward-backward asymmetry of muons, A{sub FB}(q{sup 2}), in B{yields}K{mu}{sup +}{mu}{sup -}. New physics in the form of vector/axial-vector operators does not contribute to A{sub FB}(q{sup 2}), whereas new physics in the form of scalar/pseudoscalar operators can enhance A{sub FB}(q{sup 2}) only by a few percent. However, new physics in the form of tensor operators can take the peak value of A{sub FB}(q{sup 2}) to as high as 40% near the high-q{sup 2} end point. In addition, if both scalar/pseudoscalar and tensor operators are present, then A{sub FB}(q{sup 2}) can be more than 15% for the entire high-q{sup 2} region q{sup 2}>15 GeV{sup 2}. The observation of significant A{sub FB} would imply the presence of new physics tensor operators, whereas its q{sup 2} dependence could further indicate the presence of new scalar/pseudoscalar physics.

Entropy Production at High Energy and mu_B  

E-Print Network (OSTI)

The systematics of bulk entropy production in experimental data on A+A, p+p and e+e- interactions at high energies and large mu_B is discussed. It is proposed that scenarios with very early thermalization, such as Landau's hydrodynamical model, capture several essential features of the experimental results. It is also pointed out that the dynamics of systems which reach the hydrodynamic regime give similar multiplicities and angular distributions as those calculated in weak-coupling approximations (e.g. pQCD) over a wide range of beam energies. Finally, it is shown that the dynamics of baryon stopping are relevant to the physics of total entropy production, explaining why A+A and e+e- multiplicities are different at low beam energies.

Search for heavy Majorana neutrinos in $\\mu^\\pm \\mu^\\pm$+jets events in proton-proton collisions at $\\sqrt{s}$ = 8 TeV  

E-Print Network (OSTI)

A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets ($\\mu^\\pm \\mu^\\pm \\mathrm{j j}$). The data correspond to an integrated luminosity of 19.7 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. No excess of events is observed beyond the expected standard model background and upper limits are set on $|V_{\\mu\\mathrm{N}}|^2$ as a function of Majorana neutrino mass $\\mathrm{m}_{\\mathrm{N}}$ for masses in the range of 40-500 GeV, where $|V_{\\mu\\mathrm{N}}|$ is the mixing element of the heavy neutrino with the standard model muon neutrino. The limits obtained are $|V_{\\mu\\mathrm{N}}|^2 \\le 0.00470$ for $\\mathrm{m}_{\\mathrm{N}} = 90$ GeV, $|V_{\\mu\\mathrm{N}}|^2 \\le 0.0123$ for $\\mathrm{m}_{\\mathrm{N}} = 200$ GeV, and $|V_{\\mu\\mathrm{N}}|^2 \\le 0.583$ for $\\mathrm{m}_{\\mathrm{N}} = 500$ GeV.

We are currently investigating the spatial resolution of highly pixelated Cadmium Zinc Telluride (CZT) detector for imaging applications. A 20 mm {\\times} 20 mm {\\times} 5 mm CZT substrate was fabricated with 600 {\\mu}m pitch pixels (500 {\\mu}m anode pixels with 100 {\\mu}m gap) and coplanar cathode. Charge sharing between two pixels was studied using collimated 122 keV gamma ray source.

An update for the MuCool test area  

SciTech Connect

Construction of a new facility known as the MuCool Test Area (MTA) has been completed at Fermi National Accelerator Laboratory. This facility supports research in new accelerator technologies for future endeavors such as a Neutrino Factory or Muon Collider. During the summer of 2004, an initial set of tests was completed for the filling of a convection-style liquid hydrogen absorber designed by KEK. The absorber contained 6.2 liquid liters of hydrogen and was tested for a range of heating conditions to quantify the absorber's heat exchanger performance. Future work at Fermilab includes the design, construction, and installation of a forced-flow absorber to be used with other components built to investigate the properties of a muon ionization cooling channel. A Tevatron-style refrigerator/compressor building is to be operational by spring of 2006 in support of the absorber tests and also to provide 5-K helium and liquid nitrogen to a 5-T solenoid magnet, an active element of the future test apparatus. The refrigerator will be configured in such a manner as to meet the 5 K and 14-20-K helium needs of the MTA. This paper reviews the challenges and successes of the past KEK absorber tests as well as looks into the future cryogenic capabilities and intentions of the site.

Cryogenics for the MuCool Test Area (MTA)  

SciTech Connect

MuCool Test Area (MTA) is a complex of buildings at Fermi National Accelerator Laboratory, which are dedicated to operate components of a cooling cell to be used for Muon Collider and Neutrino Factory R and D. The long-term goal of this facility is to test ionization cooling principles by operating a 25-liter liquid hydrogen (LH2) absorber embedded in a 5 Tesla superconducting solenoid magnet. The MTA solenoid magnet will be used with RF cavities exposed to a high intensity beam. Cryogens used at the MTA include LHe, LN2 and LH2. The latter dictates stringent system design for hazardous locations. The cryogenic plant is a modified Tevatron refrigerator based on the Claude cycle. The implementation of an in-house refrigerator system and two 300 kilowatt screw compressors is under development. The helium refrigeration capacity is 500 W at 14 K. In addition the MTA solenoid magnet will be batch-filled with LHe every 2 days using the same cryo-plant. This paper reviews cryogenic systems used to support the Muon Collider and Neutrino Factory R and D programs and emphasizes the feasibility of handling cryogenic equipment at MTA in a safe manner.

Thermal Design of the Mu2e Detector Solenoid  

SciTech Connect

The reference design for a superconducting Detector Solenoid (DS) for the Mu2e experiment has been completed. The main functions of the DS are to provide a graded field in the region of the stopping target which ranges from 2 T to 1 T and a uniform precision magnetic field of 1 T in a volume large enough to house a tracker downstream of the stopping target. The inner diameter of the magnet cryostat is 1.9 m and the length is 10.9 m. The gradient section of the magnet is about 4 m long and the spectrometer section with a uniform magnetic field is about 6 m long. The inner cryostat wall supports the stopping target, tracker, calorimeter and other equipment installed in the DS. This warm bore volume is under vacuum during operation. It is sealed on one end by the muon beam stop, while it is open on the other end where it interfaces with the Transport Solenoid. The operating temperature of the magnetic coil is 4.7 K and is indirectly cooled with helium flowing in a thermosiphon cooling scheme. This paper describes the thermal design of the solenoid, including the design aspects of the thermosiphon for the coil cooling, forced flow cooling of the thermal shields with 2 phase LN2 (Liquid Nitrogen) and the transient studies of the cool down of the cold mass as well.

E-Print Network (OSTI)

A search is presented for a standard model-like Higgs boson decaying to the $\\mu^+\\mu^-$ or $\\mathrm{e^+e^-}$ final states based on proton-proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0$~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $7~\\mathrm{TeV}$ and $19.7~\\mathrm{fb}^{-1}$ at $8~\\mathrm{TeV}$ for the $\\mu^+\\mu^-$ search, and of $19.7~\\mathrm{fb}^{-1}$ at a centre-of-mass energy of $8~\\mathrm{TeV}$ for the $\\mathrm{e^+e^-}$ search. To enhance the sensitivity of the search, events are categorized by topologies according to production process and dilepton invariant mass resolution. Upper limits on the production cross section times branching fraction at the 95% confidence level are reported for Higgs boson masses in the range from 120 to 150$~\\mathrm{GeV}$. For a Higgs boson with a mass of 125$~\\mathrm{GeV}$ decaying to $\\mu^+\\mu^-$, the observed (expected) upper limit on the production rate is found to be 7.4 ($6.5^{+2.8}_{-1.9}$) t...

Coulombic and radiative decay rates of the resonances of the exotic molecular ions pp{mu}, pp{pi}, dd{mu}, dd{pi}, and dt{mu}  

SciTech Connect

The bound levels and the resonances (energy and width of the excited levels) of pp{mu}-like exotic molecules for J=0 total angular momentum have been computed with an accuracy in the 10{sup -11} a.u. range, by numerical diagonalization of the complex rotated Hamiltonian in a variational sturmian basis set. For the resonances below the N=2 dissociation threshold, the x-ray spontaneous emission spectrum is computed from the wave functions. The radiative decay rate of the first resonance of pp{mu} is found to be 0.0713 ps{sup -1}, close to half that of a p{mu}(2p) atom, as expected in a simple Born-Oppenheimer picture of a resonance.

Proposal to search for mu- N -> e- N with a single event sensitivity below 10 -16  

SciTech Connect

We propose a new experiment, Mu2e, to search for charged lepton flavor violation with unprecedented sensitivity. We will measure the ratio of the coherent neutrinoless conversion in the field of a nucleus of a negatively charged muon into an electron to the muon capture process: R{sub {mu}e} = {mu}{sup -} + A(Z,N) {yields} e{sup -} + A(Z,N)/{mu}{sup -} + A(Z,N) {yields} {nu}{sub {mu}} + A(Z-1, N), with a sensitivity R{sub {mu}e} {le} 6 x 10{sup -17} at 90% CL. This is almost a four order-of-magnitude improvement over the existing limit. The observation of such a process would be unambiguous evidence of physics beyond the Standard Model. Since the discovery of the muon in 1936, physicists have attempted to answer I.I. Rabi's famous question: 'Who ordered that?' Why is there a muon? What role does it play in the larger questions of why there are three families and flavors of quarks, leptons, and neutrinos? We know quarks mix through a mechanism described by the Cabbibo-Kobayashi-Maskawa matrix, which has been studied for forty years. Neutrino mixing has been observed in the last decade, but mixing among the family of charged leptons has never been seen. The current limits are of order 10{sup -11} - 10{sup -13} so the process is rare indeed. Why is such an experiment important and timely? A major motivation for experiments at the Large Hadron Collider (LHC) is the possible observation of supersymmetric particles in the TeV mass range. Many of these supersymmetric models predict a {mu}-e conversion signal at R{sub {mu}e} {approx} 10{sup -15}. We propose to search for {mu}-e conversion at a sensitivity that exceeds this by more than an order of magnitude. The LHC may not be able to conclusively distinguish among supersymmetric models, so Mu2e will provide invaluable information should the LHC observe a signal. In the case where the LHC finds no evidence of supersymmetry, or other beyond-the-standard-model physics, Mu2e will probe for new physics at mass scales up to 10{sup 4} TeV, far beyond the reach of any planned accelerator.

6D mu (+/-) cooling using a solenoid-dipole ring cooler for a muon collider  

SciTech Connect

Six dimensional cooling of large emittance {mu}{sup +} and {mu}{sup -} beams is required in order to obtain the desired luminosity for a muon collider. We propose to use a ring cooler that employs both dipoles and solenoids with the additional requirement that the arcs of the ring be achromatic. We describe the lattice and the beam dynamics of the proposed ring, and demonstrate that the lattice gives substantial cooling in all 6 phase space dimensions.

On the model discriminating power of mu to e conversion in nuclei  

SciTech Connect

Lepton Flavor Violating (LFV) charged lepton decays provide a highly sensitive probe of physics beyond the Standard Model (SM), due to the un-observably small branching fractions ({approx}10{sup -50}) predicted for these modes in the SM (minimally extended to include massive neutrinos). Searches for SM forbidden muon processes, such as {mu} {yields} e{gamma}, {mu} {yields} e{bar e}e, and {mu} {yields} e conversion in nuclei, have provided so far the strongest constraints on LFV new physics. This statement can be characterized in a model-independent way as a lower bound on the scale associated to a set of dimension six effective operators parameterizing new physics beyond the SM. It is a well known fact that while the decay {mu} {yields} e{gamma} is only sensitive to a transition magnetic dipole operator, both {mu} {yields} e{bar e}e and {mu} {yields} e conversion in nuclei are sensitive to transition charge radii operators as well as purely contact four-fermion interactions induced by physics beyond the SM. In other words, different LFV decays have different sensitivities to underlying LFV mechanisms (effective operators). This leads naturally to ask the question whether one could infer the relative strength of these different operators in a completely phenomenological and model-independent way. This would allow one to discriminate among different underlying models of LFV and thus would provide valuable input for model building. In Ref. [1] it was pointed out that in principle, by combining the rates of {mu} {yields} e{gamma} and {mu} {yields} e conversion on different target nuclei, one could discriminate underlying models. In this work we go back to this issue with the aim to: quantify the theoretical uncertainty induced by the hadronization process; and quantify the experimental precision required to realistically infer useful information on the underlying LFV mechanisms. We organize our discussion as follows: in Section 2 we review the derivation of the {mu} {yields} e conversion rate starting from a general effective theory description of the LFV physics. In Section 3 we explore the phenomenological consequence of the simplest possible models, in which only one effective LFV operator dominates. We extend this analysis in Section 4 to the class of models in which two operators dominate. In Section 5 we specialize our discussion to the SUSY see-saw model and summarize the conclusions of our analysis in Section 6.

Nuclear 11.3$\\mu$m PAH emission in local active galactic nuclei  

E-Print Network (OSTI)

We present Gran Telescopio CANARIAS CanariCam 8.7$\\mu$m imaging and 7.5-13$\\mu$m spectroscopy of six local systems known to host an active galactic nucleus (AGN) and have nuclear star formation. Our main goal is to investigate whether the molecules responsible for the 11.3$\\mu$m polyclyclic aromatic hydrocarbon (PAH) feature are destroyed in the close vicinity of an AGN. We detect 11.3$\\mu$m PAH feature emission in the nuclear regions of the galaxies as well as extended PAH emission over a few hundred parsecs. The equivalent width (EW) of the feature shows a minimum at the nucleus but increases with increasing radial distances, reaching typical star-forming values a few hundred parsecs away from the nucleus. The reduced nuclear EW are interpreted as due to increased dilution from the AGN continuum rather than destruction of the PAH molecules. We conclude that at least those molecules responsible for the 11.3$\\mu$m PAH feature survive in the nuclear environments as close as 10pc from the AGN and for Seyfert-li...

It is inter­esting to note that Si2Br6 and Si2I6 do not form isomorphous structures. Moreover, an ortho­rhom­bic polymorph of the present structure of Si2I6 is already known. Although the title compounds feature such small and simple mol­ecules they show completely different crystal structures.

Correlations of trace elements in breast human tissues: Evaluation of spatial distribution using {mu}-XRF  

SciTech Connect

The aim of this work is to investigate microscopic correlations between trace elements in breast human tissues. A synchrotron X-ray fluorescence microprobe system ({mu}-XRF) was used to obtain two-dimensional distribution of trace element Ca, Fe, Cu and Zn in normal (6 samples) and malignant (14 samples) breast tissues. The experiment was performed in X-ray Fluorescence beam line at Laboratorio Nacional de Luz Sincrotron (LNLS), Campinas, Brazil. The white microbeam was generated with a fine conical capillary with a 20 {mu}m output diameter. The samples were supported on a XYZ table. An optical microscope with motorized zoom was used for sample positioning and choice the area to be scanned. Automatic two-dimensional scans were programmed and performed with steps of 30 {mu}m in each direction (x, y) on the selected area. The fluorescence signals were recorded using a Si(Li) detector, positioned at 90 degrees with respect to the incident beam, with a collection time of 10 s per point. The elemental maps obtained from each sample were overlap to observe correlation between trace elements. Qualitative results showed that the pairs of elements Ca-Zn and Fe-Cu could to be correlated in malignant breast tissues. Quantitative results, achieved by Spearman correlation tests, indicate that there is a spatial correlation between these pairs of elements (p < 0.001) suggesting the importance of these elements in metabolic processes associated with the development of the tumor.

ExoMol line lists VII: The rotation-vibration spectrum of phosphine up to 1500 K  

E-Print Network (OSTI)

A comprehensive hot line list is calculated for $^{31}$PH$_3$ in its ground electronic state. This line list, called SAlTY, contains almost 16.8 billion transitions between 7.5 million energy levels and it is suitable for simulating spectra up to temperatures of 1500~K. It covers wavelengths longer than 1~$\\mu$m and includes all transitions to upper states with energies below $hc \\cdot 18\\,000$~cm$^{-1}$ and rotational excitation up to $J=46$. The line list is computed by variational solution of the Schr\\"odinger equation for the rotation-vibration motion employing the nuclear-motion program TROVE. A previously reported {\\it ab initio} dipole moment surface is used as well as an updated `spectroscopic' potential energy surface (PES), obtained by refining an existing \\textit{ab initio} surface through least-squares fitting to the experimentally derived energies.

The Muon-to-Electron conversion experiment (Mu2e), under development at Fermilab, seeks to detect direct muon to electron conversion to provide evidence for a process violating muon and electron lepton number conservation that cannot be explained by the Standard Model of particle physics. The required magnetic field is produced by a series of superconducting solenoids of various apertures and lengths. This paper describes the conceptual design of the 5 T, 4 m long solenoid cold mass with 1.67 m bore with the emphasis on the magnetic, radiation and thermal analyses.

Airbreathing Laser Propulsion Experiments with 1 {mu}m Terawatt Pharos IIILaser: Part 2  

SciTech Connect

This basic research study examines the physics of airbreathing laser propulsion at the extreme flux range of 1-2x10{sup 11} W/cm{sup 2}--within the air breakdown threshold for l {mu}m radiation--using the terawatt Pharos III neodymium-glass pulsed laser. Six different experimental setups were employed using a 34 mm line focus with 66 {mu}m focal waist, positioned near the flat impulse surface. The 2nd Campaign investigated impulse generation with the laser beam focused at grazing incidence across near horizontal target surfaces, with pulse energies ranging from 55 to 186 J, and pulse-widths of 2 to 30 ns FWHM. Laser generated impulse was measured with a horizontal Plexiglas registered ballistic pendulum equipped with either a steel target insert or 0.5 Tesla permanent magnet (NEIT-40), to quantify changes in the momentum coupling coefficient (C{sub M}). Part 2 of this 2-part paper covers Campaign no. 2 results including C{sub M} performance data, and long exposure color photos of LP plasma phenomena.

CO Substitution in HOs3(CO)10(l-SC6H4Me-4) by the Diphosphine 4,5-Bis(diphenylphosphino)-4-cyclopentadiene-1,3-dione (bpcd): Structural and DFT Evaluation of the Isomeric Clusters HOs3(CO)8(bpcd)(mu-SC6H4Me-4)  

SciTech Connect

The reaction of the cluster HOs{sub 3}(CO){sub 10}({mu}-SC{sub 6}H{sub 4}Me-4) (1) with the diphosphine 4,5-bis(diphenylphosphino)-4-cyclopentadiene-1,3-dione (bpcd) has been investigated. 1 reacts with bpcd at room temperature in the presence of Me{sub 3}NO to give the isomeric clusters 1,2-HOs{sub 3}(CO)8(bpcd)({mu}-SC{sub 6}H{sub 4}Me-4) (2a) and 1,1-HOs{sub 3}(CO)8(bpcd)({mu}-SC{sub 6}H{sub 4}Me-4) (2b). Clusters 2a and 2b have been isolated, and the molecular structure of each compound has been established by X-ray crystallography. The X-ray structure of 2a confirms the coordination of one of the non-hydride-bridged Os-Os vectors by the bpcd ligand, while the structure of 2b exhibits a chelating bpcd ligand that is bound to one of the osmium centers ligated by the thiolate and hydrido ligands. 2a and 2b are stable in refluxing toluene and show no evidence for bridge-to-chelate isomerization of the ancillary bpcd ligand. DFT calculations on 2a and 2b indicate that the former cluster is the thermodynamically more stable isomer. Near-UV irradiation of 2b leads to CO loss and ortho metalation of the thiolate moiety, yielding the dihydride cluster H{sub 2}Os{sub 3}(CO)7(bpcd)({mu},{sigma}-SC{sub 6}H{sub 3}Me-4) (3). The conversion of 2b to 3 and free CO is computed to be endothermic by 14.1 kcal/mol and the reaction is driven by the entropic release of CO. The photochemically promoted ortho-metalation reaction is isomer dependent since cluster 2a is inert under identical conditions.

Broadband carbon monoxide laser system operating in the wavelength range of 2.5 - 8.3 {mu}m  

SciTech Connect

A two-cascade frequency conversion of CO-laser radiation is demonstrated in a single sample of a nonlinear ZnGeP{sub 2} crystal. The crystal is pumped by a repetitively pulsed cryogenic lowpressure CO laser operating on {approx}150 vibration - rotational transitions in the wavelength range 5.0 - 7.5 {mu}m, which corresponds to the frequency range of a half octave. In the first conversion cascade, generation of second harmonic and sum frequencies of various pairs of CO-laser radiation give {approx}350 emission lines in the wavelength range 2.5 - 3.7 {mu}m. In the second cascade, by mixing the radiation converted in the first cascade with the residual radiation of the CO laser we have obtained {approx}90 lines in the range 4.3 - 5.0 {mu}m and more than 80 lines in the range 7.5 - 8.3 {mu}m. Thus, using a single sample of the nonlinear ZnGeP{sub 2} crystal pumped by the radiation of a single CO laser we have produced a source of broadband (more than one and a half octaves) laser radiation, simultaneously operating at {approx}670 lines in the wavelength range 2.5 - 8.3 {mu}m.

An annular Si drift detector mu PIXE system using AXSIA analysis.  

SciTech Connect

Sandia and Rontec have developed an annular, 12-element, 60 mm{sup 2}, Peltier-cooled, translatable, silicon drift detector called the SDD-12. The body of the SDD-12 is only 22.8 mm in total thickness and easily fits between the sample and the upstream wall of the Sandia microbeam chamber. At a working distance of 1 mm, the solid angle is 1.09 sr. The energy resolution is 170 eV at count rates <40 kcps and 200 eV for rates of 1 Mcps. X-ray count rates must be maintained below 50 kcps when protons are allowed to strike the full area of the SDD. Another innovation with this new {mu}PIXE system is that the data are analyzed using Sandia's Automated eXpert Spectral Image Analysis (AXSIA).

Theoretical modeling and the experimental results indicate that the scattering of the laser beam by refractive index fluctuation in the alloys is the dominant loss in our lasers, and the loss due to the free-carrier absorption and scattering by interface roughness are negligible. {copyright} {ital 1996 American Institute of Physics.}

Technique for Direct eV-Scale Measurements of the Mu and Tau Neutrino Masses Using Supernova Neutrinos  

E-Print Network (OSTI)

Early black hole formation in a core-collapse supernova will abruptly truncate the neutrino fluxes. The sharp cutoff can be used to make model-independent time-of-flight neutrino mass tests. Assuming a neutrino luminosity of $10^{52}$ erg/s per flavor at cutoff and a distance of 10 kpc, SuperKamiokande can detect an electron neutrino mass as small as 1.8 eV, and the proposed OMNIS detector can detect mu and tau neutrino masses as small as 6 eV. This {\\it Letter} presents the first technique with direct sensitivity to eV-scale mu and tau neutrino masses.

We report on a recent search for {bar {nu}}{sub e} appearance from stopped {pi}{sup +} {yields} {mu}{sup +}{nu}{sub {mu}} and {mu}{sup +} {yields} e{sup +}{nu}{sub e}{bar {nu}}{sub {mu}} decay made by the LAMPF experiment E645. The appearance of {bar {nu}}{sub e} may occur from {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e}, {nu}{sub e} {yields} {bar {nu}}{sub eL}, or {nu}{sub {mu}} {yields} {bar {nu}}{sub eL} oscillations. Appearance may also occur from rare {mu}{sup +} {yields} e{sup +}{bar {nu}}{sub e}{nu}{sub {mu}} decay, which is allowed by a multiplicative lepton charge conservation law. The neutrino energies range from E{sub {nu}} = 0 to 52.8MeV. The neutrino detector, which is located 26.1 meters from the neutrino source, consists of a segmented liquid scintillator and proportional drift tube central detector surrounded by both active and passive shielding. The central detector detects {bar {nu}}{sub e} through the {bar {nu}}{sub e}p {yields} ne{sup +} Charge Current (CC) reaction, which is signaled by the direct detection of the final state positron and neutron. The hydrogen-rich liquid scintillators act as free proton targets for the {bar {nu}}{sub e}p CC reaction. The neutrons are detected through radiative neutron capture on gadolinium. We find no evidence for {bar {nu}}{sub e} appearance in the first year of running. New limits on the {bar {nu}}{sub {mu}},{nu}{sub e},{nu}{sub {mu}} {yields} {bar {nu}}{sub e} oscillation parameters and the rare {mu}{sup +} {yields} e{sup +}{bar {nu}}{sub e}{nu}{sub {mu}} decay branching ratio are presented. 87 refs., 45 figs., 17 tabs.

Revisiting the relationship between 6 {\\mu}m and 2-10 keV continuum luminosities of AGN  

E-Print Network (OSTI)

We have determined the relation between the AGN luminosities at rest-frame 6 {\\mu}m associated to the dusty torus emission and at 2-10 keV energies using a complete, X-ray flux limited sample of 232 AGN drawn from the Bright Ultra-hard XMM-Newton Survey. The objects have X-ray luminosities corrected for intrinsic absorption between 10^42 and 10^46 erg/s and redshifts from 0.05 to 2.8. The rest-frame 6 {\\mu}m luminosities were computed using data from the Wide-Field Infrared Survey Explorer and are based on a spectral energy distribution decomposition into AGN and galaxy emission. The best-fit relationship for the full sample is consistent with being linear, L_6 {\\mu}m $\\propto$ L_2-10 keV^0.99$\\pm$0.032, but has significant intrinsic scatter, ~0.35 dex in log L_6 {\\mu}m. Assuming a constant X-ray bolometric correction, the fraction of AGN bolometric luminosity reprocessed in the mid-IR decreases weakly, if at all, with the AGN luminosity, a finding at odds with simple receding torus models. Type 2 AGN have re...

SPITZER 24 {mu}m EXCESSES FOR BRIGHT GALACTIC STARS IN BOOeTES AND FIRST LOOK SURVEY FIELDS  

SciTech Connect

Optically bright Galactic stars (V {approx}< 13 mag) having f {sub {nu}}(24 {mu}m) > 1 mJy are identified in Spitzer mid-infrared surveys within 8.2 deg{sup 2} for the Booetes field of the NOAO Deep Wide-Field Survey and within 5.5 deg{sup 2} for the First Look Survey (FLS). One hundred and twenty-eight stars are identified in Booetes and 140 in the FLS, and their photometry is given. (K - [24]) colors are determined using K magnitudes from the Two Micron All Sky Survey for all stars in order to search for excess 24 {mu}m luminosity compared to that arising from the stellar photosphere. Of the combined sample of 268 stars, 141 are of spectral types F, G, or K, and 17 of these 141 stars have 24 {mu}m excesses with (K - [24]) > 0.2 mag. Using limits on absolute magnitude derived from proper motions, at least eight of the FGK stars with excesses are main-sequence stars, and estimates derived from the distribution of apparent magnitudes indicate that all 17 are main-sequence stars. These estimates lead to the conclusion that between 9% and 17% of the main-sequence FGK field stars in these samples have 24 {mu}m infrared excesses. This result is statistically similar to the fraction of stars with debris disks found among previous Spitzer targeted observations of much brighter, main-sequence field stars.

INFRARED LUMINOSITIES AND AROMATIC FEATURES IN THE 24 {mu}m FLUX-LIMITED SAMPLE OF 5MUSES  

SciTech Connect

We study a 24 {mu}m selected sample of 330 galaxies observed with the infrared spectrograph for the 5 mJy Unbiased Spitzer Extragalactic Survey. We estimate accurate total infrared luminosities by combining mid-IR spectroscopy and mid-to-far infrared photometry, and by utilizing new empirical spectral templates from Spitzer data. The infrared luminosities of this sample range mostly from 10{sup 9} L{sub sun} to 10{sup 13.5} L{sub sun}, with 83% in the range 10{sup 10} L{sub sun} < L{sub IR} < 10{sup 12} L{sub sun}. The redshifts range from 0.008 to 4.27, with a median of 0.144. The equivalent widths of the 6.2 {mu}m aromatic feature have a bimodal distribution, probably related to selection effects. We use the 6.2 {mu}m polycyclic aromatic hydrocarbon equivalent width (PAH EW) to classify our objects as starburst (SB)-dominated (44%), SB-AGN composite (22%), and active galactic nucleus (AGN)-dominated (34%). The high EW objects (SB-dominated) tend to have steeper mid-IR to far-IR spectral slopes and lower L{sub IR} and redshifts. The low EW objects (AGN-dominated) tend to have less steep spectral slopes and higher L{sub IR} and redshifts. This dichotomy leads to a gross correlation between EW and slope, which does not hold within either group. AGN-dominated sources tend to have lower log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios than star-forming galaxies, possibly due to preferential destruction of the smaller aromatics by the AGN. The log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios for star-forming galaxies are lower in our sample than the ratios measured from the nuclear spectra of nearby normal galaxies, most probably indicating a difference in the ionization state or grain size distribution between the nuclear regions and the entire galaxy. Finally, we provide a calibration relating the monochromatic continuum or aromatic feature luminosity to L{sub IR} for different types of objects.

Planetary companions in K giants beta Cancri, mu Leonis, and beta Ursae Minoris  

E-Print Network (OSTI)

Auns. The aim of our paper is to investigate the low-amplitude and long-period variations in evolved stars with a precise radial velocity (RV) survey. Methods. The high-resolution, the fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) was used from 2003 to 2013 for a radial velocity survey of giant stars as part of the exoplanet search program at Bohyunsan Optical Astronomy Observatory (BOAO). Results. We report the detection of three new planetary companions orbiting the K giants beta Cnc, mu Leo, and beta UMi. The planetary nature of the radial velocity variations is supported by analyzes of ancillary data. The HIPPARCOS photometry shows no variations with periods close to those in RV variations and there is no strong correlation between the bisector velocity span (BVS) and the radial velocities for each star. Furthermore, the stars show weak or no core reversal in Ca II H lines indicating that they are inactive stars. The companion to beta Cnc has a minimum mass of 7.8 M_Jup in a 605-day orbit wi...

Optimization of Extinction Efficiency in the 8-GeV Mu2e Beam Line  

SciTech Connect

A muon-to-electron conversion experiment at Fermilab, Mu2e, is being designed to probe for new physics beyond the standard model at mass scales up to 10{sup 4} TeV. For this experiment, the advance in experimental sensitivity will be four orders of magnitude when compared to existing data on charged lepton flavor violation. The muon beam will be produced by delivering a proton beam contained in short 100-ns bunches onto a muon production target, with an inter-bunch separation of about 1700 ns. A critical requirement of the experiment is to ensure a low level of background at the muon detector consistent with the required sensitivity. To meet the sensitivity requirement, protons that reach the target between bunches must be suppressed by an enormous factor, so that an extinction factor, defined as a number of background protons between main bunches per proton in such a bunch, should not exceed 10{sup -9}. This paper describes the advanced beam optics and results of numerical modeling with STRUCT and MARS codes for a beam line with a collimation system that allows us to achieve the experimental extinction factor of one per billion.

Effect of active layer thickness on differential quantum efficiency of 1. 3 and 1. 55. mu. m InGaAsP injection lasers  

SciTech Connect

The dependence of differential quantum efficiency (eta/sub d/) on active layer thickness (d) for 1.3 and 1.55 ..mu..m InGaAsP buried crescent (BC) injection lasers has been measured. A comparison of the results shows that eta/sub d/ for 1.55 ..mu..m lasers increases more rapidly with decreasing d than eta/sub d/ for 1.3 ..mu..m lasers. The significantly different dependence of eta/sub d/ on d in BC lasers suggests that the optical absorption in the active region of InGaAsP lasers is strongly wavelength dependent. This gives the important practical conclusion that the eta/sub d/ for 1.55 ..mu..m lasers can be significantly improved by reducing d, whereas the eta/sub d/ for 1.3 ..mu..m lasers can only be slightly improved by reducing d. As a result of eta/sub d/ vs d investigation, we have obtained high performance 1.3 and 1.55 ..mu..m BC lasers which exhibit threshold currents as low as 9 mA at 25 /sup 0/C, high-temperature operation (up to 100 /sup 0/C), and eta/sub d/ over 65% (1.3 ..mu..m) and 45% (1.55 ..mu..m).

Water in Emission in the ISO Spectrum of the Early M Supergiant Star mu Cephei  

E-Print Network (OSTI)

We report a detection of water in emission in the spectrum of the M2 supergiant atar mu Cep (M2Ia) observed by the Short Wavelength Spectrometer (SWS) aboard Infrared Space Observatory (ISO) and now released as the ISO Archives. The emission first appears in the 6 micron region (nu2 fundamental) and then in the 40 micron region (pure rotation lines) despite the rather strong dust emission. The intensity ratios of the emission features are far from those of the optically thin gaseous emission. Instead, we could reproduce the major observed emission features by an optically thick water sphere of the inner radius about two stellar radii (1300Rsun), Tex = 1500K, and Ncol (H2O) = 3.0E+20/cm2. This model also accounts for the H2O absorption bands in the near infrared (1.4, 1.9, and 2.7 micron) as well. The detection of water in emission provides strong constraints on the nature of water in the early M supergiant stars, and especially its origin in the outer atmosphere is confirmed against other models such as the large convective cell model. We finally confirm that the early M supergiant star is surrounded by a huge optically thick sphere of the warm water vapor, which may be referred to as MOLsphere for simplicity. Thus, the outer atmosphere of M supergiant stars should have a complicated hierarchical and/or hybrid structure with at least three major constituents including the warm MOLsphere (T about 1.0E+3K) together with the previously known hot chromosphere (T about 1.0E+4K) and cool expanding gas-dust envelope (T about 1.0E+2K).

Measurements of forbidden line radiation of Ar II (6. 99. mu. m) in W3 IRS 1  

SciTech Connect

Observations of the (Ar II) (6.99 ..mu..m) line flux in W3 IRS 1 are combined with previously obtained measurements of the (Ar III) (8.99 ..mu..m) line flux. The observed ratio of (Ar II)/(Ar III) is inconsistent with the calculated ratio for an H II region with the densities required by radio observations and with a central 40,000--45,000 K star with atmosphere as described by a Mihalas model. A solar effective UV radiation field is required; a dusty model we had previously invoked fits the observations. In addition we determine that the argon abundance is n(Ar)/n(H)roughly-equal8 x 10/sup -6/, a value about twice that usually adopted for normal solar abundance; however, there are uncertainties in the extinction and the model which do not allow us to preclude solar abundance.

Positive-tone silylated, dry-developed, deep ultraviolet resist with 0. 2 [mu]m resolution  

SciTech Connect

This paper describes the development of a surface-imaging process for a positive-tone silylated, dry-developed bilayer resist which has 0.2 [mu]m resolution and an aspect ratio of 4.5 using deep-UV (248 nm) exposure. The many processing variables such as thermal treatment parameters, silylation conditions, and etching conditions were examined to determine their effects on lithographic performance in terms of resolution, feature size linearity, focus latitude, and sensitivity. Critical to the success of the process are: the bilayer structure which restricts diffusion of the Si, the use of a disilane reagent to increase the Si content of the masking layer, limiting migration of photogenerated acid by the appropriate choice of softbake and post-exposure bake temperatures, initial etching with an Ar/Cl[sub 2] mixture to remove the thin layer of silylated resist in the exposed areas, and employing CO[sub 2] instead of O[sub 2] as the etching gas to eliminate lateral etching of the features. With this process we have obtained good critical dimension linearity down to 0.25 [mu]m for bright-field and dark-field lines and spaces as well as isolated lines and isolated spaces. The dose required is [similar to]75 mJ/cm[sup 2] and the dose latitude is [plus minus]6%. Focus latitude is at least [plus minus]0.4 [mu]m. We also observe no environmental effects on sensitivity or resolution.

Absorption, emission, and gain spectra of 1. 3. mu. m InGaAsP quaternary lasers  

SciTech Connect

The spontaneous emission spectrum of mesa lasers was analyzed to determine the absorption and gain spectra at threshold. The radiative current density at threshold was found to be 4.4 kA cm/sup -2/ ..mu..m/sup -1/, which is 60 percent of the total current density for the lowest threshold mesa laser. The increase in radiative lifetime due to reabsorption of emitted radiation was calculated to be 1.5, using the measured absorption and emission spectra. Contrary to other studies, this investigation of an LED and 3 lasers of different types yielded no evidence of carrier heating.

Selective enhancement of the 251-. mu. m line in an optically pumped CH/sub 3/OH laser  

SciTech Connect

To obtain a high output power on the 251-..mu..m line of a CH/sub 3/OH laser, four types of far-infrared output mirror are examined. It is found that the capacitive aluminium-mesh mirror of the Danielewicz type, which is fabricated by conventional vacuum deposition techniques in the present work, selectively extracts an output power of 18 mW from a 25-W pump. Also, exact assignment of the line is achieved by tuning the far-infrared cavity using the mirror.

Study of quasielastic scattering using charged-current nu_mu-iron interactions in the MINOS Near Detector  

E-Print Network (OSTI)

Kinematic distributions from an inclusive sample of 1.41 x 10^6 charged-current nu_mu interactions on iron, obtained using the MINOS Near Detector exposed to a wide-band beam with peak flux at 3 GeV, are compared to a conventional treatment of neutrino scattering within a Fermi gas nucleus. Results are used to guide the selection of a subsample enriched in quasielastic nu_mu Fe interactions, containing an estimated 123,000 quasielastic events of incident energies 1 = 2.79 GeV. Four additional subsamples representing topological and kinematic sideband regions to quasielastic scattering are also selected for the purpose of evaluating backgrounds. Comparisons using subsample distributions in four-momentum transfer Q^2 show the Monte Carlo model to be inadequate at low Q^2. Its shortcomings are remedied via inclusion of a Q^2-dependent suppression function for baryon resonance production, developed from the data. A chi-square fit of the resulting Monte Carlo simulation to the shape of the Q^2 distribution for the quasielastic-enriched sample is carried out with the axial-vector mass M_A of the dipole axial-vector form factor of the neutron as a free parameter. The effective M_A which best describes the data is 1.23 +0.13/-0.09 (fit) +0.12/-0.15 (syst.) GeV.

A global simulation for laser driven MeV electrons in $50\\mu m$-diameter fast ignition targets  

E-Print Network (OSTI)

The results from 2.5-dimensional Particle-in-Cell simulations for the interaction of a picosecond-long ignition laser pulse with a plasma pellet of 50-$\\mu m$ diameter and 40 critical density are presented. The high density pellet is surrounded by an underdense corona and is isolated by a vacuum region from the simulation box boundary. The laser pulse is shown to filament and create density channels on the laser-plasma interface. The density channels increase the laser absorption efficiency and help generate an energetic electron distribution with a large angular spread. The combined distribution of the forward-going energetic electrons and the induced return electrons is marginally unstable to the current filament instability. The ions play an important role in neutralizing the space charges induced by the the temperature disparity between different electron groups. No global coalescing of the current filaments resulted from the instability is observed, consistent with the observed large angular spread of th...

Room-temperature operation of an InGaAsP double-heterostructure laser emitting at 1. 55. mu. m on a Si substrate  

SciTech Connect

The room-temperature operations of an InGaAsP double-heterostructure (DH) laser emitting at 1.55 {mu}m on a Si substrate is reported. A pulsed threshold current as low as 46 mA has been measured for a ridge waveguide laser with a 4 {mu}m strip width and a 200 {mu}m cavity length. This successful laser operation is due to the high crystalline quality of the DH structure with full width at half maximum of x-ray rocking curves as low as 110 arcsec grown on a Si substrate by the organometallic vapor phase epitaxy/vapor mixing epitaxy hybrid method. A correlation between the optical property of an InGaAsP DH and its crystalline quality is also discussed.

DISCOVERY OF A RICH CLUSTER AT z = 1.63 USING THE REST-FRAME 1.6 {mu}m 'STELLAR BUMP SEQUENCE' METHOD  

SciTech Connect

We present a new two-color algorithm, the 'Stellar Bump Sequence' (SBS), that is optimized for robustly identifying candidate high-redshift galaxy clusters in combined wide-field optical and mid-infrared (MIR) data. The SBS algorithm is a fusion of the well-tested cluster red-sequence method of Gladders and Yee with the MIR 3.6 {mu}m-4.5 {mu}m cluster detection method developed by Papovich. As with the cluster red-sequence method, the SBS identifies candidate overdensities within 3.6 {mu}m-4.5 {mu}m color slices, which are the equivalent of a rest-frame 1.6 {mu}m stellar bump 'red-sequence'. In addition to employing the MIR colors of galaxies, the SBS algorithm incorporates an optical/MIR (z'-3.6 {mu}m) color cut. This cut effectively eliminates foreground 0.2 mu}m-4.5 {mu}m colors that are similarly red as z > 1.0 galaxies and add noise when searching for high-redshift galaxy overdensities. We demonstrate using the z {approx} 1 GCLASS cluster sample that similar to the red sequence, the stellar bump sequence appears to be a ubiquitous feature of high-redshift clusters, and that within that sample the color of the stellar bump sequence increases monotonically with redshift and provides photometric redshifts accurate to {Delta}z = 0.05. We apply the SBS method in the XMM-LSS SWIRE field and show that it robustly recovers the majority of confirmed optical, MIR, and X-ray-selected clusters at z > 1.0 in that field. Lastly, we present confirmation of SpARCS J022427-032354 at z = 1.63, a new cluster detected with the method and confirmed with 12 high-confidence spectroscopic redshifts obtained using FORS2 on the Very Large Telescope. We conclude with a discussion of future prospects for using the algorithm.

AKARI Observations of Brown Dwarfs. IV. Effect of Elemental Abundances to Near-Infrared Spectra between 1.0 and 5.0 {\\mu}m  

E-Print Network (OSTI)

The detection of the CO_2 absorption band at 4.2 {\\mu}m in brown dwarf spectra by AKARI has made it possible to discuss CO_2 molecular abundance in brown dwarf atmospheres. In our previous studies, we found an excess in the 4.2 {\\mu}m CO_2 absorption band of three brown dwarf spectra, and suggested that these deviations were caused by high C and O elemental abundances in their atmospheres. To validate this hypothesis we construct a set of models of brown dwarf atmospheres with various elemental abundance patterns, and investigate the variations of the molecular composition, thermal structure and their effects to the near-infrared spectra between 1.0 and 5.0 {\\mu}m. The 4.2 {\\mu}m CO_2 absorption band in some late-L and T dwarfs taken by AKARI are stronger or weaker than predictions by corresponding models with solar abundance. By comparing CO_2 band in the model spectra to the observed near-infrared spectra, we confirm possible elemental abundance variations among brown dwarfs. We find that the band strength ...

Modeling of plasma-controlled evaporation and surface condensation of Al induced by 1.06 and 0.248 {mu}m laser radiations  

SciTech Connect

Phase transition on the surface of an aluminum target and vapor plasma induced by laser irradiation in the nanosecond regime at the wavelengths of 1.06 {mu}m in the infrared range and 0.248 {mu}m in the ultraviolet range with an intensity of 10{sup 8}-10{sup 9} W/cm{sup 2} in vacuum are analyzed. Special attention is paid to the wavelength dependence of the observed phenomena and the non-one-dimensional effects caused by the nonuniform (Gaussian) laser intensity distribution and the lateral expansion of the plasma plume. A transient two-dimensional model is used which includes conductive heat transfer in the condensed phase, radiative gas dynamics, and laser radiation transfer in the plasma as well as surface evaporation and back condensation at the phase interface. It was shown that distinctions in phase transition dynamics for the 1.06 and 0.248 {mu}m radiations result from essentially different characteristics of the laser-induced plasmas. For the 1.06 {mu}m radiation, evaporation stops after the formation of hot optically thick plasma, can occasionally resume at a later stage of the pulse, and proceeds nonuniformly in the spot area, and the major contribution to the mass removal occurs in the outer part of the irradiated region. Plasma induced by the 0.248 {mu}m laser is colder and partially transparent since it transmits 30%-70% of the incident radiation; therefore evaporation does not stop but continues in the subsonic regime with the Mach number of about 0.1. The amount of evaporated matter that condenses back to the surface is as high as 15%-20% and less than 10% for the 1.06 and 0.248 {mu}m radiations, respectively. For a beam radius smaller than {approx}100 {mu}m, the screening and retarding effect of the plasma weakens because of the lateral expansion, thickness of the removed layer increases, and condensation after the end of the pulse is not observed. Comparison of the numerical and experimental results on the removed layer thickness has shown, in particular, the importance of accounting for the plasma effect to predict the correct trends for radiation intensity and beam radius.

Synthetic fluid inclusions: XIII. Experimental determination of PVT properties in the system H{sub 2}O + 40 wt% NaCl + 5 mol% CO{sub 2} at elevated temperature and pressure  

SciTech Connect

The location of the liquid + vapor {yields} liquid phase boundary and the P-T slopes of iso-Th lines were determined for a constant composition of 40 {+-} 0.1 wt% NaCl 5 {+-} 0.15 mol% CO{sub 2} (both relative) to H{sub 2}O at high density. Synthetic fluid inclusions with this composition were formed in cold-seal pressure vessels at pressures of 2 and 4 kbar and temperatures between 350{degrees}C and 700{degrees}C. The inclusions were analyzed on a gas-flow heating/cooling stage to determine the temperatures of halite dissolution [Tm{sub (H+L+V{yields}L+V)}] and total homogenization [Th{sub (L+V{yields}L)}]. Addition to 40 wt% NaCl to an aqueous solution containing 5 mol% CO{sub 2} causes a significant shift of the liquid + vapor {yields} liquid boundary towards higher pressures. The slopes of the iso-Th lines decrease from 29.5 bars/{degrees}C for Th{sub (L+V{yields}L)} of 400{degrees}C, to 6.4 bars/{degrees}C for Th{sub (L+V{yields})} = 600{degrees}C. Addition of 5 mol% CO{sub 2} to an aqueous solution containing 40 wt% NaCl results in halite dissolution temperatures that are slightly higher (Tm{sub (H+L+V{yields}L+V)} {approx} 332{degrees}C) than the literature value of 323{degrees}C for the vapor-saturated liquidus of an H{sub 2}O-40 wt% NaCl mixture. Calculated molar volumes for 40 wt% NaCl + 5 mol% CO{sub 2} solutions at 2 and 4 kbar show trends that are similar to those of other compositions in the ternary system H{sub 2}O-CO{sub 2}-NaCl at the same pressures and temperatures. In the P-T range of this study, all excess volumes are negative and lie between the values for the compositions H{sub 2}O-5 mol% CO{sub 2} and H{sub 2}O-40 wt% NaCl. 30 refs., 6 figs., 2 tabs.

Electroluminescence at 1.54 {mu}m in Si:Er/Si structures grown by sublimation molecular-beam epitaxy  

SciTech Connect

In Si:Er/Si diode structures grown by sublimation molecular-beam epitaxy in a vacuum with a pressure of {approx}10{sup -7} mbar at temperatures 520-580 deg. C, the intensity of room-temperature electroluminescence at 1.54 {mu}m is studied as a function of the concentration and distribution of erbium and donor impurities in the space-charge region (SCR) and the SCR width. Methods for obtaining electroluminescence in diodes with a wide (0.1-1 {mu}m) SCR are developed. The mean free path of electrons with respect to their interaction with Er centers and the threshold energy a free electron needs in order to excite an Er-shell electron are determined. The values of electric-field strength corresponding to breakdown in silicon p-i-n diodes with and without Er doping are obtained experimentally. A model describing the interaction of hot electrons with Er centers is suggested.

We place an upper limit on the branching ratio at 3.9x10{sup -11} (90% C.L.). Together with results based on data collected in 1995 and an earlier experiment, E777, this result establishes a combined 90% confidence level upper limit on the branching ratio at 2.8x10{sup -11} .

Frequency stabilization of 1. 5-. mu. m InGaAsP distributed feedback laser to NH/sub 3/ absorption lines  

SciTech Connect

NH/sub 3/ absorption lines due to vibration-rotation transitions are observed at 1.50--1.54 ..mu..m by using an InGaAsP superluminescent diode. A 1.5-..mu..m InGaAsP distributed feedback (DFB) laser is frequency stabilized to an NH/sub 3/ linear absorption line at 15196 A. Frequency stability of sigma(2,tau) = 8 x 10/sup -11/tau/sup -1/ is achieved for an averaging time range of 10 ms< or =tau< or =1 s. Such an absolute frequency-stabilized DFB laser is useful for coherent optical system applications, since it is free from the longitudinal mode jumping which results from a wide range of temperature changes and long-term device degradation.

THE CARNEGIE HUBBLE PROGRAM: THE LEAVITT LAW AT 3.6 AND 4.5 {mu}m IN THE MILKY WAY  

SciTech Connect

The Carnegie Hubble Program (CHP) is designed to calibrate the extragalactic distance scale using data from the post-cryogenic era of the Spitzer Space Telescope. The ultimate goal of the CHP is a systematic improvement in the distance scale leading to a determination of the Hubble constant to within an accuracy of 2%. This paper focuses on the measurement and calibration of the Galactic Cepheid period-luminosity (PL, Leavitt) relation using the warm Spitzer/IRAC 1 and 2 bands at 3.6 and 4.5 {mu}m. We present photometric measurements covering the period range 4-70 days for 37 Galactic Cepheids. Data at 24 phase points were collected for each star. Three PL relations of the form M = a(log (P) - 1) + b are derived. The method adopted here takes the slope a to be -3.31, as determined from the Spitzer Large Magellanic Cloud (LMC) data of Scowcroft et al. Using the geometric Hubble Space Telescope guide-star distances to 10 Galactic Cepheids, we find a calibrated 3.6 {mu}m PL zero point of -5.80 {+-} 0.03. Together with our value for the LMC zero point, we determine a reddening-corrected distance modulus of 18.48 {+-} 0.04 mag to the LMC. The mid-IR period-color diagram and the [3.6]-[4.5] color variation with phase are interpreted in terms of CO absorption at 4.5 {mu}m. This situation compromises the use of the 4.5 {mu}m data for distance determinations.

THE COMPTON-THICK SEYFERT 2 NUCLEUS OF NGC 3281: TORUS CONSTRAINTS FROM THE 9.7 {mu}m SILICATE ABSORPTION  

SciTech Connect

We present mid-infrared (mid-IR) spectra of the Compton-thick Seyfert 2 galaxy NGC 3281, obtained with the Thermal-Region Camera Spectrograph at the Gemini-South telescope. The spectra present a very deep silicate absorption at 9.7 {mu}m, and [S IV] 10.5 {mu}m and [Ne II] 12.7 {mu}m ionic lines, but no evidence of polycyclic aromatic hydrocarbon emission. We find that the nuclear optical extinction is in the range 24 mag {<=} A{sub V} {<=} 83 mag. A temperature T = 300 K was found for the blackbody dust continuum component of the unresolved 65 pc nucleus and the region at 130 pc SE, while the region at 130 pc NW reveals a colder temperature (200 K). We describe the nuclear spectrum of NGC 3281 using a clumpy torus model that suggests that the nucleus of this galaxy hosts a dusty toroidal structure. According to this model, the ratio between the inner and outer radius of the torus in NGC 3281 is R{sub 0}/R{sub d} = 20, with 14 clouds in the equatorial radius with optical depth of {tau}{sub V} = 40 mag. We would be looking in the direction of the torus equatorial radius (i = 60{sup 0}), which has outer radius of R{sub 0} {approx} 11 pc. The column density is N{sub H} {approx} 1.2 x 10{sup 24} cm{sup -2} and the iron K{alpha} equivalent width ({approx}0.5-1.2 keV) is used to check the torus geometry. Our findings indicate that the X-ray absorbing column density, which classifies NGC 3281 as a Compton-thick source, may also be responsible for the absorption at 9.7 {mu}m providing strong evidence that the silicate dust responsible for this absorption can be located in the active galactic nucleus torus.

Ternary mutual diffusion coefficients of NaCl-SrCl/sub 2/-H/sub 2/O at 25/degrees/C. 2. Total concentrations of 2. 0 and 3. 0 mol/times/dm/sup /minus/3/  

SciTech Connect

Mutual diffusion coefficients were measured for aqueous NaCl-SrCl/sub 2/ mixtures at 25/degrees/C by using free-diffusion Rayleigh interferometry. These mixtures were total molarities of 2.0 and 3.0 mol/times/dm/sup /minus/3/ with molarity fractions of 2/3, 1/2, and 1/3, the results complement the authors earlier data at 0.5 and 1.0 mol/times/dm/sup /minus/3/. At a constant molarity ratio, the NaCl main-term coefficient decreases regularly by 19-36% with increasing concentration, in contrast, the SrCl/sub 2/ main-term coefficient is relatively constant, with 18% or less variation with concentration. The SrCl/sub 2/ cross-term coefficient is 7-23% of its corresponding main-term coefficient, whereas the NaCl cross-term coefficient varies from 8% to 73% of its corresponding main-term coefficient. Clearly, coupled diffusion is very important for these systems. Various estimation procedures were considered, including variations using the Nernst-Hartley equations and estimates from the corresponding binary solutions. None of these methods, for which sufficient auxiliary data are available, gave reliable estimates of diffusion coefficients for mixtures. At a total molarity of 3.0 mol/times/dm/sup /minus/3/ and molarity fractions of 1/2 and 1/3 NaCl, experiments with the SrCl/sub 2/ ..delta..c approx. 0 are convectively unstable with regard to fingering at the center of the boundary. Density data were also measured for the above systems.

Author manuscript, published in "Information and Software Technology (2011)" DOI: 10.1016/j.infsof.2011.09.006 API2MoL: Automating the building of bridges between APIs and Model- Driven Engineering  

E-Print Network (OSTI)

Context. A software artefact typically makes its functionality available through a specialized Application Programming Interface (API) describing the set of services offered to client applications. In fact, building any software system usually involves managing a plethora of APIs, which complicates the development process. In Model-Driven Engineering (MDE), where models are the key elements of any software engineering activity, this API management should take place at the model level. Therefore, tools that facilitate the integration of APIs and MDE are clearly needed. Objective. Our goal is to automate the implementation of API-MDE bridges for supporting both the creation of models from API objects and the generation of such API objects from models. In this sense, this paper presents the API2MoL approach, which provides a declarative rule-based language to easily write mapping definitions to link API specifications and the metamodel that represents them. These definitions are then executed to convert API objects into model elements or vice versa. The approach also allows both the metamodel and the mapping to be automatically obtained from the API specification (bootstrap process). Method. After implementing the API2MoL engine, its correctness was validated using several APIs.

EXPLAINING THE [C II]157.7 {mu}m DEFICIT IN LUMINOUS INFRARED GALAXIES-FIRST RESULTS FROM A HERSCHEL/PACS STUDY OF THE GOALS SAMPLE  

SciTech Connect

We present the first results of a survey of the [C II]157.7 {mu}m emission line in 241 luminous infrared galaxies (LIRGs) comprising the Great Observatories All-sky LIRG Survey (GOALS) sample, obtained with the PACS instrument on board the Herschel Space Observatory. The [C II] luminosities, L{sub [C{sub II]}}, of the LIRGs in GOALS range from {approx}10{sup 7} to 2 Multiplication-Sign 10{sup 9} L{sub Sun }. We find that LIRGs show a tight correlation of [C II]/FIR with far-IR (FIR) flux density ratios, with a strong negative trend spanning from {approx}10{sup -2} to 10{sup -4}, as the average temperature of dust increases. We find correlations between the [C II]/FIR ratio and the strength of the 9.7 {mu}m silicate absorption feature as well as with the luminosity surface density of the mid-IR emitting region ({Sigma}{sub MIR}), suggesting that warmer, more compact starbursts have substantially smaller [C II]/FIR ratios. Pure star-forming LIRGs have a mean [C II]/FIR {approx} 4 Multiplication-Sign 10{sup -3}, while galaxies with low polycyclic aromatic hydrocarbon (PAH) equivalent widths (EWs), indicative of the presence of active galactic nuclei (AGNs), span the full range in [C II]/FIR. However, we show that even when only pure star-forming galaxies are considered, the [C II]/FIR ratio still drops by an order of magnitude, from 10{sup -2} to 10{sup -3}, with {Sigma}{sub MIR} and {Sigma}{sub IR}, implying that the [C II]157.7 {mu}m luminosity is not a good indicator of the star formation rate (SFR) for most local LIRGs, for it does not scale linearly with the warm dust emission most likely associated to the youngest stars. Moreover, even in LIRGs in which we detect an AGN in the mid-IR, the majority (2/3) of galaxies show [C II]/FIR {>=} 10{sup -3} typical of high 6.2 {mu}m PAH EW sources, suggesting that most AGNs do not contribute significantly to the FIR emission. We provide an empirical relation between the [C II]/FIR and the specific SFR for star-forming LIRGs. Finally, we present predictions for the starburst size based on the observed [C II] and FIR luminosities which should be useful for comparing with results from future surveys of high-redshift galaxies with ALMA and CCAT.

A SEARCH FOR C II 158 {mu}m LINE EMISSION IN HCM 6A, A Ly{alpha} EMITTER AT z = 6.56  

SciTech Connect

We report a Plateau de Bure Interferometer search for C II 158 {mu}m emission from HCM 6A, a lensed Ly{alpha} emitter (LAE) at z = 6.56. Our non-detections of C II 158 {mu}m line emission and 1.2 mm radio continuum emission yield 3{sigma} limits of L{sub CII} < 6.4 x 10{sup 7} x ({Delta}V/100 km s{sup -1}){sup 1/2} L{sub Sun} for the C II 158 {mu}m line luminosity and S{sub 1.2mm} < 0.68 mJy for the 1.2 mm flux density. The local conversion factor between L{sub CII} and the star formation rate (SFR) yields an SFR < 4.7 M{sub Sun} yr{sup -1}, Almost-Equal-To 2 times lower than that inferred from the ultraviolet (UV) continuum, suggesting that the local factor may not be applicable in high-z LAEs. The non-detection of 1.2 mm continuum emission yields a total SFR < 28 M{sub Sun} yr{sup -1}; any obscured star formation is thus within a factor of two of the visible star formation. Our best-fit model to the rest-frame UV/optical spectral energy distribution of HCM 6A yields a stellar mass of 1.3 Multiplication-Sign 10{sup 9} M{sub Sun} and an SFR of Almost-Equal-To 10 M{sub Sun} yr{sup -1}, with negligible dust obscuration. We fortuitously detect CO J = 3-2 emission from a z = 0.375 galaxy in the foreground cluster A370, and obtain a CO line luminosity of L'(CO) > (8.95 {+-} 0.79) Multiplication-Sign 10{sup 8} K km s{sup -1} pc{sup 2} and a molecular gas mass of M(H{sub 2}) > (4.12 {+-} 0.36) Multiplication-Sign 10{sup 9} M{sub Sun }, for a CO-to-H{sub 2} conversion factor of 4.6 M{sub Sun} (K km s{sup -1} pc{sup 2}){sup -1}.

Measurement of {nu}{sub {mu}} and {nu}{sub e} Events in an Off-Axis Horn-Focused Neutrino Beam  

SciTech Connect

We report the first observation of off-axis neutrino interactions in the MiniBooNE detector from the NuMI beam line at Fermilab. The MiniBooNE detector is located 745 m from the NuMI production target, at 110 mrad angle (6.3 deg.) with respect to the NuMI beam axis. Samples of charged-current quasielastic {nu}{sub {mu}} and {nu}{sub e} interactions are analyzed and found to be in agreement with expectation. This provides a direct verification of the expected pion and kaon contributions to the neutrino flux and validates the modeling of the NuMI off-axis beam.

Leading order hadronic contributions to a{sub {mu}} and {alpha}{sub QED} from N{sub f} = 2 + 1 + 1 twisted mass fermions  

SciTech Connect

We present the first four-flavour lattice calculation of the leading-order hadronic vacuum polarisation contribution to the anomalous magnetic moment of the muon, a{sub {mu}}{sup hvp}, and the hadronic running of the QED coupling constant, {Delta}{alpha}{sup hvp}{sub QED}(Q{sup 2}). In the heavy sector a mixed-action setup is employed. The bare quark masses are determined from matching the K- and D-meson masses to their physical values. Several light quark masses are used in order to yield a controlled extrapolation to the physical pion mass by utilising a recently proposed improved method. We demonstrate that this method also works in the four-flavour case.

Above room-temperature operation of InAs/AlGaSb superlattice quantum cascade lasers emitting at 12 {mu}m  

SciTech Connect

The authors report on above-room-temperature operation of InAs/AlGaSb quantum cascade lasers emitting at 12 {mu}m. The laser structures are grown on a n-InAs (100) substrate using solid-source molecular beam epitaxy. An InAs/AlGaSb superlattice is used as an active part and an InAs double plasmon waveguide is used for optical confinement. Results show that increased doping concentration in the injection part of the active region expands the current operation range of the devices, allowing laser operation at and above room temperature. The observed threshold current density is 4.0 kA/cm{sup 2} at 300 K; the maximum operation temperature is 340 K.

Diode laser measurements of H[sub 2]O line intensities and self-broadening coefficients in the 1. 4-[mu]m region  

SciTech Connect

Precise knowledge of water vapor radiative properties in the infrared spectrum is needed for many applications. Such applications include atmospheric sounding experiments, radiative sensing of combustion processes, and optical diagnostics for gas-dynamic and aerodynamic studies. Spectrally resolved measurements of pure water vapor absorption spectra have been performed with a tunable diode laser. The laser, a distributed feedback InGaAsP diode, emits in the 1.4-[mu]m region. A total of 12 lines were studied corresponding to rovibrational transitions within the [nu][sub 1] + [nu][sub 3] and 2[nu][sub 1] vibrational bands. A Voigt profile analysis of lineshape is used to infer both intensities and self-collision-broadening coefficients of the water vapor. Good agreements is found between the observed line intensities and those recently measured by Toth. These results are apparently the first published measurements of the broadening coefficient within this spectral range.

FIRST DETECTIONS OF THE [N II] 122 {mu}m LINE AT HIGH REDSHIFT: DEMONSTRATING THE UTILITY OF THE LINE FOR STUDYING GALAXIES IN THE EARLY UNIVERSE  

SciTech Connect

We report the first detections of the [N II] 122 {mu}m line from a high-redshift galaxy. The line was strongly (>6{sigma}) detected from SMMJ02399-0136, and H1413+117 (the Cloverleaf QSO) using the Redshift (z) and Early Universe Spectrometer on the Caltech Submillimeter Observatory. The lines from both sources are quite bright with line to far-infrared (FIR) continuum luminosity ratios that are {approx}7.0 x 10{sup -4} (Cloverleaf) and 2.1 x 10{sup -3} (SMMJ02399). With ratios 2-10 times larger than the average value for nearby galaxies, neither source exhibits the line-to-continuum deficits seen in nearby sources. The line strengths also indicate large ionized gas fractions, {approx}8%-17% of the molecular gas mass. The [O III]/[N II] line ratio is very sensitive to the effective temperature of ionizing stars and the ionization parameter for emission arising in the narrow-line region (NLR) of an active galactic nucleus (AGN). Using our previous detection of the [O III] 88 {mu}m line, the [O III]/[N II] line ratio for SMMJ02399-0136 indicates that the dominant source of the line emission is either stellar H II regions ionized by O9.5 stars, or the NLR of the AGN with ionization parameter log(U) = -3.3 to -4.0. A composite system, where 30%-50% of the FIR lines arise in the NLR also matches the data. The Cloverleaf is best modeled by a superposition of {approx}200 M82-like starbursts accounting for all of the FIR emission and 43% of the [N II] line. The remainder may come from the NLR. This work demonstrates the utility of the [N II] and [O III] lines in constraining properties of the ionized medium.

FIRST DETECTION OF THE [O III] 88 {mu}m LINE AT HIGH REDSHIFTS: CHARACTERIZING THE STARBURST AND NARROW-LINE REGIONS IN EXTREME LUMINOSITY SYSTEMS  

SciTech Connect

We have made the first detections of the 88 {mu}m [O III] line from galaxies in the early universe, detecting the line from the lensed active galactic nucleus (AGN)/starburst composite systems APM 08279+5255 at z = 3.911 and SMM J02399-0136 at z = 2.8076. The line is exceptionally bright from both systems, with apparent (lensed) luminosities {approx}10{sup 11} L {sub sun}. For APM 08279, the [O III] line flux can be modeled in a star formation paradigm, with the stellar radiation field dominated by stars with effective temperatures, T {sub eff} > 36,000 K, similar to the starburst found in M82. The model implies {approx}35% of the total far-IR luminosity of the system is generated by the starburst, with the remainder arising from dust heated by the AGN. The 88 {mu}m line can also be generated in the narrow-line region of the AGN if gas densities are around a few 1000 cm{sup -3}. For SMM J02399, the [O III] line likely arises from H II regions formed by hot (T {sub eff} > 40,000 K) young stars in a massive starburst that dominates the far-IR luminosity of the system. The present work demonstrates the utility of the [O III] line for characterizing starbursts and AGN within galaxies in the early universe. These are the first detections of this astrophysically important line from galaxies beyond a redshift of 0.05.

WISE TF: A MID-INFRARED, 3.4 {mu}m EXTENSION OF THE TULLY-FISHER RELATION USING WISE PHOTOMETRY  

SciTech Connect

We present a mid-infrared Tully-Fisher (TF) relation using photometry from the 3.4 {mu}m W1 band of the Wide-field Infrared Survey Explorer (WISE) satellite. The WISE TF relation is formed from 568 galaxies taken from the all-sky 2MASS Tully-Fisher (2MTF) galaxy catalog, spanning a range of environments including field, group, and cluster galaxies. This constitutes the largest mid-infrared TF relation constructed to date. After applying a number of corrections to galaxy magnitudes and line widths, we measure a master TF relation given by M{sub corr} = -22.24 - 10.05[log (W{sub corr}) - 2.5], with an average dispersion of {sigma}{sub WISE} = 0.686 mag. There is some tension between WISE TF and a preliminary 3.6 {mu}m relation, which has a shallower slope and almost no intrinsic dispersion. However, our results agree well with a more recent relation constructed from a large sample of cluster galaxies. We additionally compare WISE TF to the near-infrared 2MTF template relations, finding a good agreement between the TF parameters and total dispersions of WISE TF and the 2MTF K-band template. This fact, coupled with typical galaxy colors of (K - W1) {approx} 0, suggests that these two bands are tracing similar stellar populations, including the older, centrally-located stars in the galactic bulge which can (for galaxies with a prominent bulge) dominate the light profile.

Ternary mutual diffusion coefficients of NaCl-SrCl/sub 2/-H/sub 2/O at 25/sup 0/C. 1. Total concentrations of 0. 5 and 1. 0 mol. dm/sup -3/  

SciTech Connect

Mutual diffusion coefficients have been measured for aqueous NaCl-SrCl/sub 2/ mixtures at 25/sup 0/C by using free-diffusion Rayleigh interferometry. These diffusion experiments were done at total molarities of 0.5 and 1.0 mol x dm/sup -3/ and with molarity fractions of 1/3, 1/2, and 2/3. Main-term diffusion coefficients for NaCl and SrCl/sub 2/ show a 10-15% variation with concentration and composition. Coupled diffusion is important for these systems, with cross-term diffusion coefficients being 6.5-36% as large as their corresponding main terms. At a constant molarity ratio, doubling the concentration causes cross-term diffusion coefficients to increase. Attempts to estimate the ternary solution diffusion coefficients from those of their corresponding binary solutions or from the ternary solution analogues of the Nernst-Hartley equation do not yield particularly accurate results.

Selection Tests of MnZn and NiZn Ferrites for Mu2e 300 kHz and 5.1 MHz AC Dipoles  

SciTech Connect

Mu2e, a charged lepton flavor violation (CLFV) experiment is planned to start at Fermilab late in this decade. The proposed experiment will search for neutrinoless muon to electron conversions with unprecedented sensitivity, better than 6 x 10{sup -17 }at 90% CL. To achieve this sensitivity the incoming proton beam must be highly suppressed during the window for detecting the muon decays. The current proposal for beam extinction is based on a collimator design with two dipoles running at {approx}300 kHz and 5.1 MHz and synchronized to the proton bunch spacing. The appropriate choice of ferrite material for the magnet yoke is a critical step in the overall design of the dipoles and their reliable operation at such high frequencies over the life of the experiment. This choice, based on a series of the thermal and magnetic measurements of the ferrite samples, is discussed in the paper. Additionally, the first results from the testing at 300 kHz of a prototype AC dipole are presented.

Temperature-dependent collision-broadening parameters of H[sub 2]O lines in the 1. 4-[mu]m region using diode laser absorption spectroscopy  

SciTech Connect

Radiative properties of water vapor in the infrared spectrum are important in a variety of applications, including atmospheric sounding experiments, radiative sensing of combustion processes, and optical diagnostics for gasdynamic and aerodynamic studies. Here, spectrally resolved measurements of water vapor absorption spectra near 1.4 [mu]m have been performed with a tunable, distributed-feedback InGaAsP diode laser. A lineshape analysis was used to infer the collision-broadening coefficient of 11 rovibrational transitions in the [nu] + [nu][sub 3] and 2[nu][sub 1] vibration bands perturbed separately by N[sub 2], O[sub 2], CO[sub 2], and H[sub 2]. The temperature dependence of the broadening coefficients was determined using a temperature-controlled static cell and a pressure-driven shock tube over the range 300--1,200 K. The measured coefficients are in good agreement with the previous calculations of Delaye. Also, agreement is found between prior experimental data, obtained for the same rotational transitions but different vibration bands, and the results.

Measurements of line strengths in the HO sub 2. nu. sub 1 overtone band at 1. 5. mu. m using an InGaAsP laser  

SciTech Connect

The hydroperoxyl radical, HO{sub 2}, is a pivotal atmospheric species, being closely coupled to OH, the most important oxidant in both tropospheric and stratospheric chemistry. The authors report the first observation of resolved rotational-vibrational overtone (2{nu}{sub 1}) absorptions of the hydroperoxyl radical (HO{sub 2}) in the 1.5-{mu}m region, using two-tone frequency modulation spectroscopy (TTFMS) with an InGaAsP laser diode and White-cell optics. Photolysis of Cl{sub 2}/H{sub 2}O{sub 2} mixtures was used to produce the HO{sub 2}, and the concentration was determined by modulated-photolysis UV absorption spectroscopy. The line center adsorption cross sections for the strongest lines ranged between 1.3 {times} 10{sup {minus}20} and 10 {times} 10{sup {minus}20} cm{sup 2} molecule{sup {minus}1} under Doppler-limited conditions. For the strongest line this corresponds to an integrated line strength S of 1.6 {times} 10{sup {minus}21} cm{sup 2} molecule{sup {minus}1} cm{sup {minus}1}, a line strength of the same order of magnitude as lines previously observed in the relatively weak {nu}{sub 1} fundamental.

SeD Radical: A probe for measurement of time variation of Fine Structure Constant($\\alpha$) and Proton to Electron Mass Ratio($\\mu$)  

E-Print Network (OSTI)

Based on the spectroscopic constants derived from highly accurate potential energy surfaces, the SeD radical is identified as a spectroscopic probe for measuring spatial and temporal variation of fundamental physical constants such as the fine-structure constant (denoted as $\\alpha=\\frac{e^2}{\\hbar c}$) and the proton-to-electron mass ratio (denoted as $\\mu=\\frac{m_p}{m_e}$). The ground state of SeD ($X^2\\Pi$), due to spin-orbit coupling, splits into two fine structure multiplets $^2\\Pi_{\\frac{3}{2}}$ and $^2\\Pi_{\\frac{1}{2}}$. The potential energy surfaces of these spin-orbit components are derived from a state of the art electronic structure method, MRCI+Q inclusive of scalar relativistic effects with the spin-orbit effects accounted through the Breit-Pauli operator. The relevant spectroscopic data are evaluated using Murrel-Sorbie fit to the potential energy surfaces.

THE 0.5-2.22 {mu}m SCATTERED LIGHT SPECTRUM OF THE DISK AROUND TW Hya: DETECTION OF A PARTIALLY FILLED DISK GAP AT 80 AU  

SciTech Connect

We present a 0.5-2.2 {mu}m scattered light spectrum of the circumstellar disk around TW Hya from a combination of spatially resolved Hubble Space Telescope STIS spectroscopy and NICMOS coronagraphic images of the disk. We investigate the morphology of the disk at distances >40 AU over this wide range of wavelengths, and identify the presence of a depression in surface brightness at {approx}80 AU that could be caused by a gap in the disk. Additionally, we quantify the surface brightness, azimuthal symmetry, and spectral character of the disk as a function of radius. Our analysis shows that the scattering efficiency of the dust is largely neutral to blue over the observed wavelengths. We model the disk as a steady {alpha}-disk with an ad hoc gap structure. The thermal properties of the disk are self-consistently calculated using a three-dimensional radiative transfer code that uses ray tracing to model the heating of the disk interior and scattered light images. We find a good fit to the data over a wide range of distances from the star if we use a model disk with a partially filled gap of 30% depth at 80 AU and with a self-similar truncation knee at 100 AU. The origin of the gap is unclear, but it could arise from a transition in the nature of the disk's dust composition or the presence of a planetary companion. Based on scalings to previous hydrodynamic simulations of gap-opening criteria for embedded proto-planets, we estimate that a planetary companion forming the gap could have a mass between 6 and 28 M{sub Circled-Plus }.

A wide-bandwidth low-noise InGaAsP-InAlAs superlattice avalanche photodiode with a flip-chip structure for wavelengths of 1. 3 and 1. 55 [mu]m  

SciTech Connect

This paper reports the fabrication of a flip-chip InGaAsP-InAlAs superlattice avalanche photodiode using gas source molecular beam epitaxy. The incident light reaches the InGaAs photoabsorption layer through the InP substrate and an InGaAsP-InAlAs superlattice multiplication region which are transparent for wavelengths of 1.55 and 1.3 [mu]m. The light reflection by the electrode enables the absorption layer to be as thin as 0.8 [mu]m without significantly reducing the quantum efficiency. A maximum bandwidth of 17 GHz was obtained at a low multiplication factor because of the transit time through the absorption layer is reduced.

MULTI-WAVELENGTH STUDY OF A COMPLETE IRAC 3.6 {mu}m SELECTED GALAXY SAMPLE: A FAIR CENSUS OF RED AND BLUE POPULATIONS AT REDSHIFTS 0.4-1.2  

SciTech Connect

We present a multi-wavelength study of a 3.6 {mu}m selected galaxy sample in the Extended Groth Strip (EGS). The sample is complete for galaxies with stellar mass >10{sup 9.5} M{sub Sun} and redshift 0.4 < z < 1.2. In this redshift range, the Infrared Array Camera 3.6 {mu}m band measures the rest-frame near-infrared band, permitting nearly unbiased selection with respect to both quiescent and star-forming galaxies. The numerous spectroscopic redshifts available in the EGS are used to train an artificial neural network to estimate photometric redshifts. The distribution of photometric redshift errors is Gaussian with standard deviation {approx}0.025(1 + z), and the fraction of redshift failures (>3{sigma} errors) is about 3.5%. A new method of validation based on pair statistics confirms the estimate of standard deviation even for galaxies lacking spectroscopic redshifts. Basic galaxy properties measured include rest-frame U - B colors, B- and K-band absolute magnitudes, and stellar masses. We divide the sample into quiescent and star-forming galaxies according to their rest-frame U - B colors and 24-3.6 {mu}m flux density ratios and derive rest K-band luminosity functions and stellar mass functions for quiescent, star-forming, and all galaxies. The results show that massive, quiescent galaxies were in place by z Almost-Equal-To 1, but lower mass galaxies generally ceased their star formation at later epochs.

Spectral-kinetic properties of heterostructures with GaAsSb/InGaAs/GaAs-based quantum wells emitting in the range of 1.0-1.2 {mu}m  

SciTech Connect

The spectral-kinetic properties of heterostructures with GaAs/GaAsSb-based and GaAsSb/InGaAs/GaAs-based quantum wells, emitting in the range of 1.0-1.2 {mu}m are studied with picosecond and nanosecond temporal resolution. Intense photoluminescence in the GaAsSb/InGaAs/GaAs structure, as well as an increase in the photoluminescence wavelength by a factor of 2.5 and a shift of the location of the maximum of the peak ({approx}100 meV) to the longer-wavelength region were observed up to room temperature. It is established that as the molar fraction of Sb and the thickness of the InGaAs layer increase, the energy of the fundamental transition decreases by a factor of 140 meV compared with the GaAsSb/InGaAs/GaAs structure with a lower Sb content and a smaller thickness of the InGaAs layer. At 300 K, the emission wavelength of such a structure was 1.18 {mu}m. In addition, an increase in the thickness of the InGaAs layer led to an increase in the room-temperature photoluminescence intensity by a factor of 60, which is associated with a decrease in the energy of the fundamental state for electrons in the InGaAs layer and, consequently, to larger electron localization and smaller temperature quenching of photoluminescence.

Some conclusive considerations on the comparison of the ICARUS nu_mu to nu_e oscillation search with the MiniBooNE low-energy event excess  

E-Print Network (OSTI)

A sensitive search for anomalous LSND-like nu_mu to nu_e oscillations has been performed by the ICARUS Collaboration exposing the T600 LAr-TPC to the CERN to Gran Sasso (CNGS) neutrino beam. The result is compatible with the absence of additional anomalous contributions giving a limit to oscillation probability of 3.4E-3 and 7.6E-3 at 90% and 99% confidence levels respectively showing a tension between these new limits and the low-energy event excess (200 energy excess has been performed, including the energy resolution as obtained from the official MiniBooNE data release. As a result the previously reported tension is confirmed at 90% C.L., suggesting an unexplained nature or an otherwise instrumental effect for the MiniBooNE low energy event excess

Optical remote monitoring of CH/sub 4/ gas using low-loss optical fiber link and InGaAsP light-emitting diode in 1. 33-. mu. m region  

SciTech Connect

Purely optical remote monitoring of low-level CH/sub 4/ gas is realized for the first time by the method employing a 2-km long-distance, low-loss silica optical fiber link and a compact absorption cell in conjunction with a high radiant InGaAsP light-emitting diode (LED) at 1.33 ..mu..m. Based on the present experiment, the detection limit of CH/sub 4/ in air was confirmed to be approximately 2000 ppm, i.e., 4% of the lower explosion limit of CH/sub 4/. This result supports the conclusion that the fully optical remote sensing system incorporating ultralow loss optical fiber networks and near infrared LEDs or laser diodes can be extensively used for the detection and surveillance of various inflammable and/or explosive gases in industrial and mining complexes as well as in residential areas.

THE SOLAR NEIGHBORHOOD. XXV. DISCOVERY OF NEW PROPER MOTION STARS WITH 0.''40 yr{sup -1} > {mu} {>=} 0.''18 yr{sup -1} BETWEEN DECLINATIONS -47{sup 0} AND 00{sup 0}  

SciTech Connect

We present 2817 new southern proper motion systems with 0.''40 yr{sup -1} > {mu} {>=} 0.''18 yr{sup -1} and declination between -47{sup 0} and 00{sup 0}. This is a continuation of the SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky. We use the same photometric relations as previous searches to provide distance estimates based on the assumption that the objects are single main-sequence stars. We find 79 new red dwarf systems predicted to be within 25 pc, including a few new components of previously known systems. Two systems-SCR 1731-2452 at 9.5 pc and SCR 1746-3214 at 9.9 pc-are anticipated to be within 10 pc. We also find 23 new white dwarf (WD) candidates with distance estimates of 15-66 pc, as well as 360 new red subdwarf candidates. With this search, we complete the SCR sweep of the southern sky for stars with {mu} {>=} 0.''18 yr{sup -1} and R{sub 59F} {<=} 16.5, resulting in a total of 5042 objects in 4724 previously unreported proper motion systems. Here we provide selected comprehensive lists from our SCR proper motion search to date, including 152 red dwarf systems estimated to be within 25 pc (9 within 10 pc), 46 WDs (10 within 25 pc), and 598 subdwarf candidates. The results of this search suggest that there are more nearby systems to be found at fainter magnitudes and lower proper motion limits than those probed so far.

THE SOLAR NEIGHBORHOOD. XXVII. DISCOVERY OF NEW PROPER MOTION STARS WITH {mu} {>=} 0.''18 yr{sup -1} IN THE SOUTHERN SKY WITH 16.5 < R{sub 59F} {<=} 18.0  

SciTech Connect

Here we present 1584 new southern proper motion systems with {mu} {>=} 0.''18 yr{sup -1} and 16.5 > R{sub 59F} {>=} 18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky for stars within the same proper motion range, but with R{sub 59F} {<=} 16.5. As in previous papers, we present distance estimates for these systems and find that three systems are estimated to be within 25 pc, including one, SCR 1546-5534, possibly within the RECONS 10 pc horizon at 6.7 pc, making it the second nearest discovery of the searches. We find 97 white dwarf candidates with distance estimates between 10 and 120 pc, as well as 557 cool subdwarf candidates. The subdwarfs found in this paper make up nearly half of the subdwarf systems reported from our SCR searches and are significantly redder than those discovered thus far. The SCR searches have now found 155 red dwarfs estimated to be within 25 pc, including 10 within 10 pc. In addition, 143 white dwarf candidates and 1155 cool subdwarf candidates have been discovered. The 1584 systems reported here augment the sample of 4724 systems previously discovered in our SCR searches and imply that additional systems fainter than R{sub 59F} = 18.0 are yet to be discovered.

Flocculation-dispersion characteristics of alumina using a wide molecular weight range of polyacrylic acids  

Science Journals Connector (OSTI)

The effects of polymer molecular weight on the flocculation/dispersion behavior of a model colloidal system consisting of alumina and polyacrylic acid (PAA) were investigated. Low molecular weight polymers, traditionally used as dispersants were discovered to flocculate alumina at ultra low concentrations. For molecular weights ranging from 2000 to 50?000 g mol?1, distinct concentration ranges were found to exist in which the polymer behaved as a flocculant and above which it behaved as a dispersant. With increasing molecular weight, the number of polymer molecules required to achieve a benchmark flocculation (80% flocculation) decreased down to the molecular weight of 250?000 g mol?1 PAA. Above this size, there was no significant advantage of increasing the molecular weight. It was observed that regardless of the sign of the zeta potential, flocculation of alumina could be obtained with PAA suggesting that in addition to electrostatics, other forces such as bridging by hydrogen bonding are also responsible for the flocculation.

Kern River 650{degrees}F{sup +} residuum and Midway Sunset crude oil were examined by micropyrolysis at several constant-heating rates to determine pyrolysis cracking kinetics. Determined by the discrete distribution method, both feeds exhibited principal activation energies of 50 kcal/mol and frequency factors {approximately}10{sup 13} sec{sup -1}. Energy distributions were similar ranging from 45 to 57 kcal/mol. Determined by the shift-in-T{sub max} method, the E{sub approx} and A{sub {approx}} for Kern River 650{degrees}F{sup +} and Midway Sunset were 48 kcal/mol, 1.3 X 10{sup 12} sec{sup -1}, and 46 kcal/mol and 4.6 X 10{sup 11} sec{sup -1}, respectively. These results are similar, but not identical to other kinetic parameters for heavy oils from type II source rocks.

Gas-Phase Oxidation of Cm+ and Cm2+ -- Thermodynamics of neutral and ionized CmO  

SciTech Connect

Fourier transform ion cyclotron resonance mass spectrometry was employed to study the products and kinetics of gas-phase reactions of Cm+ and Cm2+; parallel studies were carried out with La+/2+, Gd+/2+ and Lu+/2+. Reactions with oxygen-donor molecules provided estimates for the bond dissociation energies, D[M+-O](M = Cm, Gd, Lu). The first ionization energy, IE[CmO], was obtained from the reactivity of CmO+ with dienes, and the second ionization energies, IE[MO+](M = Cm, La, Gd, Lu), from the rates of electron-transfer reactions from neutrals to the MO2+ ions. The following thermodynamic quantities for curium oxide molecules were obtained: IE[CmO]= 6.4+-0.2 eV; IE[CmO+]= 15.8+-0.4 eV; D[Cm-O]= 710+-45 kJ mol-1; D[Cm+-O]= 670+-40 kJ mol-1; and D[Cm2+-O]= 342+-55 kJ mol-1. Estimates for the M2+-O bond energies for M = Cm, La, Gd and Lu are all intermediate between D[N2-O]and D[OC-O]--i.e., 167 kJ mol-1< D[M2+-O]< 532 kJ mol-1 -- such that the four MO2+ ions fulfill the thermodynamic requirement for catalytic O-atom transport from N2O to CO. It was demonstrated that the kinetics are also favorable and that the CmO2+, LaO2+, GdO2+ and LuO2+ dipositive ions each catalyze the gas-phase oxidation of CO to CO2 by N2O. The CmO2+ ion appeared during the reaction of Cm+ with O2 when the intermediate, CmO+, was not collisionally cooled -- although its formation is kinetically and/or thermodynamically unfavorable, CmO2+ is a stable species.

Control of enhanced optical absorption in {mu}c-Si  

SciTech Connect

The influence of grain size on the enhanced optical absorption of {micro}c-Si has been investigated using films of various grain sizes prepared by solid phase crystallization. The authors show that they can control this grain size and therefore the degree of absorption changes. For grain sizes below a threshold range significant absorption enhancement can be seen in the photon energy range of 1 to {approximately}3 eV and the absorption characteristics of these films show that the dominant mode of optical transitions is indirect. A correlation between first order Raman peak broadening and enhanced absorption was found suggesting both effects are related to confinement. A simple model was developed to see how confinement in the crystallites could influence indirect optical transitions.

SciTech Connect

By using the hindered tris(pyrazoly)borate ligand HB(3,5-iPr[sub 2]pz)[sub 3], (hydrotris(3,5-diisopropyl-1-pyrazolyl)-borate), a series of hydroxo complexes of first-row divalent metal ions (Mn (1), Fe (2), Co (3), Ni (4), Cu (5), Zn (6)) was synthesized. X-ray crystallography was applied to 1-5, establishing that all these hydroxo complexes have a dinuclear structure solely bridged with a bis(hydroxo) unit. The structure of 6 was characterized by spectroscopy, which indicates that 6 is monomeric. All these hydroxo complexes were found to react with CO[sub 2], even atmospheric CO[sub 2], to afford [mu]-carbonato dinuclear complexes of Mn (7), Fe (8), Co (9), Ni (10), Cu (11), and Zn (12). The molecular structures of the complexes 8-12 were determined. A variety of coordination modes of the carbonate group was seen. In 10 and 11, the carbonate group is bound to both metal centers bidentately in a symmetric fashion, while in 8 and 9, the carbonate coordination modes are described as an unsymmetric bidentate. The carbonate group in 12 is coordinated to one zinc ion bidentately, but it is bound to the other zinc ion unidentately. From IR data, the coordination mode of the carbonate group in 7 was suggested to be similar to those found in 8 and 9. Thus, the order of the coordination distortions of the carbonate groups in this series of [mu]-carbonato dinuclear complexes is determined. 40 refs., 8 figs., 4 tabs.

Theoretical Investigation of the Enzymatic Phosphoryl Transfer of ?-phosphoglucomutase: Revisiting Both Steps of the Catalytic Cycle  

SciTech Connect

Enzyme catalyzed phosphate transfer is a part of almost all metabolic processes. Such reactions are of central importance for the energy balance in all organisms and play important roles in cellular control at all levels. Mutases transfer a phosphoryl group while nucleases cleave the phosphodiester linkages between two nucleotides. The subject of our present study is the Lactococcus lactis ?-phosphoglucomutase (?-PGM), which effectively catalyzes the interconversion of ?-D-glucose-1-phosphate (?-G1P) to ?- D-glucose-6-phosphate (?-G6P) and vice versa via stabile intermediate ?-D-glucose-1,6-(bis)phosphate (?-G1,6diP) in the presence of Mg2+. In this paper we revisited the reaction mechanism of the phosphoryl transfer starting from the bisphosphate ?-G1,6diP in both directions (toward ?-G1P and ?-G6P) combining docking techniques and QM/MM theoretical method at the DFT/PBE0 level of theory. In addition we performed NEB (nudged elastic band) and free energy calculations to optimize the path and to identify the transition states and the energies involved in the catalytic cycle. Our calculations reveal that both steps proceed via dissociative pentacoordinated phosphorane, which is not a stabile intermediate but rather a transition state. In addition to the Mg2+ ion, Ser114 and Lys145 also play important roles in stabilizing the large negative charge on the phosphate through strong coordination with the phosphate oxygens and guiding the phosphate group throughout the catalytic process. The calculated energy barrier of the reaction for the ?-G1P to ?-G1,6diP step is only slightly higher than for the ?-G1,6diP to ?-G6P step (16.10 kcal mol-1 versus 15.10 kcal mol-1) and is in excellent agreement with experimental findings (14.65 kcal mol-1).

Thermochemical Insight into the Reduction of CO to CH3OH with [Re(CO)]+ and [Mn(CO)]+ Complexes  

SciTech Connect

To gain insight into thermodynamic barriers for reduction of CO into CH3OH, free energies for reduction of [CpRe(PPh3)(NO)(CO)]+ into CpRe(PPh3)(NO)(CH2OH) have been determined from experimental measurements. Using model complexes, the free energies for the transfer of H+, H–, and e– have been determined. A pKa of 10.6 was estimated for [CpRe(PPh3)(NO)(CHOH)]+ by measuring the pKa for the analogous [CpRe(PPh3)(NO)(CMeOH)]+. The hydride donor ability (?G°H–) of CpRe(PPh3)(NO)(CH2OH) was estimated to be 58.0 kcal mol1, based on calorimetry measurements of the hydride transfer reaction between CpRe(PPh3)(NO)(CHO) and [CpRe(PPh3)(NO)(CHOMe)]+ to generate the methylated analog, CpRe(PPh3)(NO)(CH2OMe). Cyclic voltammograms recorded on CpRe(PPh3)(NO)(CMeO), CpRe(PPh3)(NO)(CH2OMe), and [CpRe(PPh3)(NO)(CHOMe)]+ displayed either a quasireversible oxidation (neutral species) or reduction (cationic species). These potentials were used as estimates for the oxidation of CpRe(PPh3)(NO)(CHO) or CpRe(PPh3)(NO)(CH2OH), or the reduction of [CpRe(PPh3)(NO)(CHOH)]+. Combination of the thermodynamic data permits construction of three-dimensional free energy landscapes under varying conditions of pH and PH2. The free energy for H2 addition (?G°H2) to [CpRe(PPh3)(NO)(CO)]+ (+15 kcal mol1) was identified as the most significant thermodynamic impediment for the reduction of CO. DFT computations indicate that ?G°H2 varies by only 4.3 kcal mol1 across a series of [CpXRe(L)(NO)(CO)]+, while the experimental ?G°H– values for the analogous series of CpRe(PPh3)(NO)(CHO) varies by 12.9 kcal mol1. The small range of ?G°H2 values is attributed to a minimal change in the C–O bond polarization upon modification of the ancillary ligands, as determined from the computed atomic charges.

Non-destructive characterization of films grown on Zircaloy-2 by annealing in air  

Science Journals Connector (OSTI)

Zircaloy-2 is often used in engineering applications because of its corrosion resistance; a property attributable to a protective oxide film that grows on its surface. Variable angle infrared (IR) reflection spectroscopy and atomic force microscopy are used to determine the thickness and roughness of such films grown thermally on Zircaloy-2 surfaces in air. We find cubic growth kinetics in the temperature range 500-600°C with an apparent activation energy of 227 kJ mol-1. We also demonstrate how an increase in microscopic surface roughness at higher temperatures correlates with a loss of oxide homogeneity as sampled by the IR method.

Threshold Photoelectron Photoion Coincidence (TPEPICO) Studies: The Road to ? 0.1 kJ/mol Thermochemistry  

SciTech Connect

The threshold photoelectron photoion coincidence (TPEPICO) technique is utilized to investigate the dissociation dynamics and thermochemistry of energy selected medium to large organic molecular ions. The reactions include parallel and consecutive steps that are modeled with the statistical theory in order to extract dissociation onsets for multiple dissociation paths. These studies are carried out with the aid of molecular orbital calculations of both ions and the transition states connecting the ion structure to their products. The results of these investigations yield accurate heats of formation of ions, free radicals, and stable molecules. In addition, they provide information about the potential energy surface that governs the dissociation process. Isomerization reactions prior to dissociation are readily inferred from the TPEPICO data.

Enhancement of photosynthetic performance, water use efficiency and grain yield during long-term growth under elevated CO2 in wheat and rye is growth temperature and cultivar dependent  

Science Journals Connector (OSTI)

Abstract The effects of long-term elevated CO2 on photosynthetic performance of winter (cv Musketeer) and spring (cv SR4A) rye (Secale cereale) and winter (cv Norstar) and spring (cv Katepwa) wheat (Triticum aestivum) grown at either 20/16 °C (non-acclimated (NA)) or 5/5 °C (cold acclimated (CA) and at either ambient (380 ?mol C mol?1) or elevated (700 ?mol C mol?1) CO2 were studied. Compared to NA counterparts, CA winter cereals exhibited a 30–40% increase in light and CO2-saturated rates of photosynthesis at both ambient and elevated CO2. This was accompanied by a 35–50% decrease in excitation pressure and non-photochemical energy dissipation. Concomitantly, biomass increased by 28–46% and grain yield per plant by 60%. In contrast, both CA spring cultivars exhibited a 45–60% inhibition of light- and CO2-saturated rates of photosynthesis at ambient CO2 as well as growth at elevated CO2 relative to NA controls. This inhibition was specific for photosynthesis since cold acclimation stimulated rates of respiration by 22–47% in all cultivars tested. This was accompanied by a 58% increase in excitation pressure and a 17% increase in non-photochemical energy dissipation in the cold acclimated spring rye and spring wheat. Consequently, biomass accumulation was reduced by about 25% in CA versus NA spring cultivars at elevated CO2. We conclude that the potential for enhancement of photosynthetic performance, water use efficiency and grain yield of cereals grown at elevated CO2 is both growth temperature and cultivar dependent.

Effects of sugars in batter formula and baking conditions on 5-hydroxymethylfurfural and furfural formation in sponge cake models  

Science Journals Connector (OSTI)

5-Hydroxymethylfurfural (HMF) and furfural (F) could be formed in sugar-rich foods during baking. The effects of batter formula and baking conditions on the formation of HMF and F and the kinetics of HMF formation during baking were studied in 15 sponge cake models. A fixed amount of sucrose (40%) was included as minimum in sponge cake models to improve the batter consistency and texture of sponge cakes. The results showed that increase of the sugar and citric acid amount in the batter formula increased HMF and F formation during baking at 205 °C for 11 min. With increasing of the baking temperature and time, the concentrations of HMF and F were also increased in the sponge cake models, and the maximum concentrations of HMF and F attained were 4100 ± 11 mg kg? 1 and 59 ± 1 mg kg? 1, respectively. Formation of HMF in the sponge cake models (Models 11–15) followed a first-order kinetics. By applying the Arrhenius equation, the activation energy (Ea) of sponge cake models was found to a span range between 15.4 kJ mol1 and 25.8 kJ mol1. The results showed that sugar type, pH and baking temperature and time strongly affected HMF and F formation in sponge cake models.

Computational Study of Bond Dissociation Enthalpies for Substituted $\\beta$-O-4 Lignin Model Compounds  

SciTech Connect

The biopolymer lignin is a potential source of valuable chemicals. Phenethyl phenyl ether (PPE) is representative of the dominant $\\beta$-O-4 ether linkage. Density functional theory (DFT) is used to calculate the Boltzmann-weighted carbon-oxygen and carbon-carbon bond dissociation enthalpies (BDEs) of substituted PPE. These values are important in order to understand lignin decomposition. Exclusion of all conformers that have distributions of less than 5\\% at 298 K impacts the BDE by less than 1 kcal mol$^{-1}$. We find that aliphatic hydroxyl/methylhydroxyl substituents introduce only small changes to the BDEs (0-3 kcal mol$^{-1}$). Substitution on the phenyl ring at the $ortho$ position substantially lowers the C-O BDE, except in combination with the hydroxyl/methylhydroxyl substituents, where the effect of methoxy substitution is reduced by hydrogen bonding. Hydrogen bonding between the aliphatic substituents and the ether oxygen in the PPE derivatives has a significant influence on the BDE. CCSD(T)-calculated BDEs and hydrogen bond strengths of $ortho$-substituted anisoles when compared with M06-2X values confirm that the latter method is sufficient to describe the molecules studied and provide an important benchmark for lignin model compounds.

Crossed beam reaction of atomic carbon C ( 3 P j ) with hydrogen sulfide, H 2 S (X 1 A 1 ): Observation of the thioformyl radical, HCS (X 2 A?)  

Science Journals Connector (OSTI)

One of the simplest organosulfur reactions that between ground statecarbon atoms C ( 3 P j ) and hydrogen sulfide H 2 S (X 1 A 1 ) was studied at an average collision energy of 21.0 kJ? mol ?1 using the crossed molecular beams technique. The product angular distribution and time-of-flight spectra of m/e=45 ( HC 32 S ) were monitored. Forward-convolution fitting of our data yields an almost isotropic center-of-mass angular flux-distribution whereas the center-of-mass translational energy flux distribution peaks at about 50 kJ? mol ?1 indicating a tight exit transition state from the decomposing thiohydroxycarbene HCSH complex to the reaction products. The high energy cut-off of the translational energy flux distribution is consistent with the formation of the thioformyl radical HCS in its X 2 A electronic ground state. The first experimental verification of an existing thiohydroxycarbene intermediate and the rigorous assignment of the HCS radical product under single collision conditions explicitly suggest inclusion of the title reaction in chemical reaction networks of molecular clouds TMC-1 and OMC-1 the outflow of the carbon star IRC+10216 Shoemaker/Levy 9 impact-induced nonequilibrium sulfur chemistry in the Jovian atmosphere as well as combustion of sulfur containing coal.

Kinetic model for the catalytic disproportionation of pine oleoresin over Pd/C catalyst  

Science Journals Connector (OSTI)

Abstract The kinetics of the disproportionation of pine oleoresin (a renewable bioresource) over a carbon-supported palladium catalyst was studied. Kinetic experiments, constructed to eliminate internal and external mass transfer limitations, were performed in the temperature range of 210–250 °C. The samples, withdrawn from reaction mixtures at different intervals, were determined by GC–MS and GC. A new reaction scheme together with a lumped kinetic model was proposed to describe the complex reaction system. The kinetic parameters for each involved reaction were estimated using the Levenberg–Marquart method by MATLAB software. The various activation energies of rosin acids in pine oleoresin, for the isomerization, dehydrogenation and hydrogenation reactions, were 83.05–172.75 kJ mol?1. The various activation energies of monoterpenes in pine oleoresin, for the dehydrogenation and hydrogenation reactions, were 103.97–133.82 kJ mol?1. The kinetic model well fitted the experimental observations and could be used to predict the concentration distribution of the products at 260 °C. The results showed that the disproportionations of rosin acids and monoterpenes followed second order and first order reactions, respectively. In addition, dehydrogenation was the main reaction in the disproportionation of pine oleoresin. Dehydrogenated acid and p-cymene were main components in the final products.

Differential and integral enthalpies of solution of akermanite and pseudo-wollastonite in the melts of the system Ca2MgSi2O7?CaSiO3. Isoplethal enthalpies in this system  

Science Journals Connector (OSTI)

It was found that the enthalpy of mixing at formation of the melts in the Ca2MgSi2O7?CaSiO3 system from melts of Ca2MgSi2O7 and CaSiO3 is zero within the temperature limits from 1673 to 1930 K. Consequently, the differential and integral heats of solution of akermanite and pseudo-wollastonite in the melts of this system are equal to their heats of fusion at the corresponding temperature. Using the non-isothermal Hess law and the phase diagram, isoplethal enthalpies were calculated in this system within the temperature range from 298 to 1920 K. The enthalpy and entropy of crystallization for the eutectic melt at the eutectic temperature Te = 1673 K was determined to be ?crystH(eut. melt, Te) = (? 78.3 +- 2.4) J mol?1 and ?crystS(eut. melt, Te) = (?46.8 +- 1.4) J mol?1 K?1, respectively.

Lattice for a 1. 1-GeV 500. mu. A fast-cycling proton synchrotron  

SciTech Connect

A very-high-intensity proton synchrotron lattice has been designed for a spallation neutron-source system. The synchrotron is to accelerate a beam of 6.25 x 10/sup 13/ protons from 200 MeV to 1100 MeV in 15 msec. One of the important concerns for high-intensity, high-rep-rate (50 pulses/sec) machines is stability of the beam. Considerations of the transverse space-charge limits and the transverse-stability criterion favor a high-tune machine over a low-tune machine of the same circumference. For these reasons, we made the tune as high as possible by making the cell length as short as possible. The lattice proposed here consists of four sectors, and each sector is made up by three FODO normal cells, four dispersion suppressor cells, and four matching and straight section cells. Then the total of 44 cells with approximately 90/sup 0//cell phase advance would make the natural tune of the machine to be near 11.

VHF plasma deposition of {mu}c-Si p-layer materials  

SciTech Connect

Microcrystalline silicon ({micro}c-Si) p-layers have been widely used in amorphous silicon (a-Si) solar cell research and manufacturing to achieve record high solar cell efficiency. In order to further improve the solar cell performance and achieve wider parameter windows for the process conditions, the authors studied the deposition of high quality {micro}c-Si p-layer material using a very high frequency (VHF) plasma enhanced CVD process. A design of experiment (DOE) approach was used for the exploration and optimization of deposition parameters. The usage of DOE leads to a quick optimization of the deposition process within a short time frame. In addition, by using a modified VHF deposition process, they have improved the solar cell blue response which leads to a 6--10% improvement in the solar cell efficiency. Such an improvement is likely due to an improved microcrystalline formation in the p-layer.

Fixing Two-Nucleon Weak-Axial Coupling L_{1,A} From mu-d Capture

We calculate the muon capture rate on the deuteron to next-to-next-to-leading order in the pionless effective field theory. The result can be used to constrain the two-nucleon isovector axial coupling L_{1,A} to +/- 2 fm^3 if the muon capture rate is measured to 2% level. From this, one can determine the neutrino-deuteron break up reactions and the pp-fusion cross section in the sun to a same level of accuracy.

Kinetic determination of a highly reactive impregnated Fe2O3/Al2O3 oxygen carrier for use in gas-fueled Chemical Looping Combustion  

Science Journals Connector (OSTI)

Abstract The objective of this work was to determine the kinetic parameters for reduction and oxidation reactions of a highly reactive Fe-based oxygen carrier for use in Chemical Looping Combustion (CLC) of gaseous fuels containing CH4, CO and/or H2, e.g. natural gas, syngas and PSA-off gas. The oxygen carrier was prepared by impregnation of iron on alumina. The effect of both the temperature and gas concentration was analyzed in a thermogravimetric analyzer (TGA). The grain model with uniform conversion in the particle and reaction in grains following the shrinking core model (SCM) was used for kinetics determination. It was assumed that the reduction reactions were controlled by two different resistances: the reaction rate was controlled by chemical reaction in a first step, whereas the mechanism that controlled the reactions at higher conversion values was diffusion through the product layer around the grains. Furthermore, it was found that the reduction reaction mechanism was based on the interaction of Fe2O3 with Al2O3 in presence of the reacting gases to form FeAl2O4 as the only stable Fe-based phase. The reaction order values found for the reducing gases were 0.25, 0.3 and 0.6 for CH4, H2 and CO, respectively, and the activation energy took values of between 8 kJ mol?1 (for H2) and 66 kJ mol?1 (for CH4). With regard to oxidation kinetics, the reacting model assumed a reaction rate that was only controlled by chemical reaction. Values of 0.9 and 23 kJ mol?1 were found for reaction order and activation energy, respectively. Finally, the solids inventory needed in a CLC system was also estimated by considering kinetic parameters. The total solids inventory in the CLC unit took a minimum value of 150 kg MW?1 for CH4 combustion, which is a low value when compared to those of other Fe-based materials found in the literature.

The photosynthetic acclimation of Lolium perenne in response to three years growth in a free-air CO{sub 2} enrichment (FACE) system  

SciTech Connect

Pure stands of Ryegrass were in their third year of growth in the field, exposed to either ambient (355 {mu}mol mol{sup -1}), or elevated (600 {mu}mol mol{sup -1}) atmospheric CO{sub 2} concentration. A Free-Air CO{sub 2} Enrichment (FACE) system was used to maintain the elevated CO{sub 2} concentration whilst limiting experimental constraints on the field conditions. The theoretically predicted increase in the net rates of CO{sub 2} uptake per unit leaf area (A {mu}mol mol{sup -1}) as a consequence, primarily, of the suppression of photorespiration by CO{sub 2} a competitive inhibitor of RubP oxygenation by Rubisco, was observed for the Lolium perenne studied. Also observed was a general decline in leaf evapotranspiration (E) consistent with observations of increased water use efficiency of crops grown in elevated CO{sub 2}. Enhancement of leaf A in the FACE grown L. perenne ranged from 26.5 1 % to 44.95% over the course of a diurnal set of measurements. Whilst reductions in leaf E reached a maximum of 16.61% over the same diurnal course of-measurements. The increase in A was reconciled with an absence of the commonly observed decline in V{sub c}{sub max} as a measure of the maximum in vivo carboxylation capacity of the primary carboxylasing enzyme Rubisco and J{sub max} a measure of the maximum rate of electron transport. The manipulation of the source sink balance of the crop, stage of canopy regrowth or height in the canopy had no effect on the observation of a lack of response. The findings of this study will be interpreted with respect to the long term implications of C{sub 3} crops being able to adapt physiologically to maximize the potential benefits conferred by growth in elevated CO{sub 2}.

Kinetic studies on chromium-catalyzed conversion of glucose into 5-hydroxymethylfurfural in alkylimidazolium chloride ionic liquid  

Science Journals Connector (OSTI)

Abstract 5-Hydroxymethylfurfural (HMF) is a promising green platform chemical derived from biomass. Kinetic studies were performed on chromium chloride-catalyzed conversion of glucose into HMF in alkylimidazolium chloride ionic liquids. The main by-products are disaccharides, fructose, glyceraldehyde, formic acid, and humins. The formation of HMF is strongly affected by reaction temperature and initial glucose concentration. The reaction is second order in glucose, with an activation energy of 134.9 kJ mol?1. The order in chromium is first, indicating that the rate-determining isomerization reaction is catalyzed by a mononuclear chromium species. The observed glucose conversion rate constant decreases as initial glucose concentration increases, suggesting that the catalytic activity of the chloride anion is significantly restrained by the hydrogen bonding with hydroxyl groups. A simplified kinetic model is developed to describe the behaviors of glucose conversion and HMF formation. This model is in good agreement with the experimental results.

Atomistic Details of the Associative Phosphodiester Cleavage in Human Ribonuclease H  

SciTech Connect

During translation of the genetic information of DNA into proteins, mRNA is synthesized by RNA polymerase and after the transcription process degraded by RNase H. The endoribonuclease RNase H is a member of the nucleotidyl-transferase (NT) superfamily and is known to hydrolyze the phosphodiester bonds of RNA which is hybridized to DNA. Retroviral RNase H is part of the viral reverse transcriptase enzyme that is indispensable for the proliferation of retroviruses, such as HIV. Inhibitors of this enzyme could therefore provide new drugs against diseases like AIDS. In our study we investigated the molecular mechanism of RNA cleavage by human RNase H using a comprehensive high level DFT/B3LYP QM/MM theoretical method for the calculation of the stationary points and nudged elastic band (NEB) and free energy calculations to identify the transition state structures, the rate limiting step and the reaction barrier. Our calculations reveal that the catalytic mechanism proceeds in two steps and that the nature of the nucleophile is a water molecule. In the first step, the water attack on the scissile phosphorous is followed by a proton transfer from the water to the O2P oxygen and a trigonal bipyramidal pentacoordinated phosphorane is formed. Subsequently, in the second step the proton is shuttled to the O30 oxygen to generate the product state. During the reaction mechanism two Mg2+ ions support the formation of a stable associated in-line SN2-type phosphorane intermediate. Our calculated energy barrier of 19.3 kcal mol*1 is in excellent agreement with experimental findings (20.5 kcal mol*1). These results may contribute to the clarification and understanding of the RNase H reaction mechanism and of further enzymes from the RNase family.

The photosynthetic acclimation response of Lolium perenne to four years growth in a free-air CO{sub 2} enrichment (FACE) facility  

SciTech Connect

In this study, the photosynthetic responses of field grown Lolium perenne to ambient (354 {mu}mol mol{sup -1}) and elevated (600 {mu}mol mol{sup -1}) C{sub a} were measured. The experiment utilized the FACE facility at Eschikon, Switzerland; here the L. Perenne swards had been grown at two nitrogen treatments, with six cuts per year, for 4 years. The study revealed a significant decrease in Rubisco activity (Vcmax) in the low nitrogen FACE plots; this is consistent with the theories of source-sink imbalance resulting in feedback inhibition and down-regulation. Such negative acclimation was not wholly supported by diurnal investigations which revealed an average stimulation of 53.38% and 52.78% in the low and high nitrogen, respectively. However, light response curves and AI investigations also suggested down-regulation, especially in the low nitrogen. SI is expected to decrease in response to elevated C{sub a}, if any change is seen. This was indeed observed in the high nitrogen plots but for the low nitrogen a significant increase was found. Conclusions drawn from this project center around the implications of negative acclimation to future crop productivity. For instance, inter-specific differences in response to elevated C{sub a} may result in ecosystem changes and new management techniques may be necessary. However, real predictions cannot be made from leaf level studies alone as these may not represent the overall changes at the whole plant level.

Urinary 1-hydroxypyrene concentrations in Chinese coke oven workers relative to job category, respirator usage, and cigarette smoking  

SciTech Connect

1-Hydroxypyrene (1-OHP) is a biomarker of recent exposure to polycyclic aromatic hydrocarbons (PAHs). We investigated whether urinary 1-OHP concentrations in Chinese coke oven workers (COWs) are modulated by job category, respirator usage, and cigarette smoking. The present cross-sectional study measured urinary 1-OHP concentrations in 197 COWs from Coking plant I and 250 COWs from Coking plant II, as well as 220 unexposed referents from Control plant I and 56 referents from Control plant II. Urinary 1-OHP concentrations (geometric mean, {mu}mol/mol creatinine) were 5.18 and 4.21 in workers from Coking plants I and II, respectively. The highest 1-OHP levels in urine were found among topside workers including lidmen, tar chasers, and whistlers. Benchmen had higher 1-OHP levels than other workers at the sideoven. Above 75% of the COWs exceeded the recommended occupational exposure limit of 2.3 {mu}mol/mol creatinine. Respirator usage and increased body mass index (BMI) slightly reduced 1-OHP levels in COWs. Cigarette smoking significantly increased urinary 1-OHP levels in unexposed referents but had no effect in COWs. Chinese COWs, especially topside workers and benchmen, are exposed to high levels of PAHs. Urinary 1-OHP concentrations appear to be modulated by respirator usage and BMI in COWs, as well as by smoking in unexposed referents.

Recovery of propylene glycol from dilute aqueous solutions by reversible chemical complexation with organoboronates  

SciTech Connect

Extractants consisting of an ion-pair of Aliquat 336 with phenylboronate or 3-nitrophenylboronate were prepared in various diluents (2-ethylhexanol, toluene, o-xylene or diisobutylketone). In batch experiments propyleneglycol (1,2-PD) was effectively extracted even at low concentrations. Heterogeneous complexation constants {beta}{sub 11} calculated at 25 C were 45-120 (mol/1){sup {minus}1} in 2-ethylhexanol, 34.8 (mol/l){sup {minus}1} in toluene, 37.6 (mol/l){sup {minus}1} in o-xylene and 14.4 (mol/l){sup {minus}1} in diisobutylketone. In 2-ethythexanol, there was no significant effect of extractant concentration on the complexation constant. Equilibrium water concentration in the extractants was 8-12 wt %, decreasing with 1,2-PD uptake. Nearly all extractant/diluent systems exhibited overloading (more than stoichiometric uptake of 1,2-PD). Evidence for aggregation of the ion-pair extractant in organic phase was found from water solubilization studies (molar solubilization ratios up to 10) and {sup 1}H NMR spectroscopy studies. Solubilization of 1,2-PD within hydrophilic aggregate interiors may explain the observed overloading. The complexation constant decreased with increasing temperature, but not enough to make back extraction after a temperature change attractive. Back extraction may be achieved after acidification with carbon dioxide to convert the organoboronate anion to the corresponding organoboronic acid. Up to 80% of the extracted 1,2-PD was backextracted in a batch extraction using C0{sub 2}. The extractant could then be regenerated by stripping carbon dioxide from solution at temperatures exceeding 110 C. However, at these temperatures the extractant appears to undergo a transformation in which color changes and extraction capacity is reduced to about 60% of original value.

A new intense proton beam will be used to produce a conventional horn focused neutrino beam directed at a detector located in either the Homestake mine in Lead, South Dakota at 2540 km or the Waste Isolation Pilot Plant (WIPP) in Carlsbad, NM at 2880 km. As a continuation of the study that produced the letter of intent, this report examines several items in more detail. We mainly concentrate on the use of water Cherenltov detectors because of their size, resolution, and background rejection capability, and cost. We examine the prospects of building such a detector in the Homestake mine. The accelerator upgrade will be carried out in phases. We expect the first phase to yield a 0.4 MW proton beam and the second phase to result in a 1.0 MW beam. The details of this upgrade will be reported in a companion report. In this report we assume accelerator intensity of 1 MW for calculating event rates and spectra. We also assume a total experimental duration of 5 years with running time of 10{sup 7} seconds per year. We examine the target station and the horn produced neutrino beam with focus on two topics: target and horn design for a 1 MW beam and the broad band spectrum of neutrinos from a 28 GeV proton beam.

Gas Phase Photoacoustic Sensor at 8.41 mu m Using Quartz Tuning Forks and Amplitude Modulated Quantum Cascade Lasers  

SciTech Connect

We demonstrate the performance of a novel long-wave infrared photoacoustic laser absorbance spectrometer for gas-phase species using an amplitude modulated (AM) quantum cascade (QC) laser and a quartz tuning fork microphone. Photoacoustic signal was generated by focusing the output of a Fabry-Perot QC laser operating at 8.41 ?m between the legs of a quartz tuning fork which served as a transducer for the transient acoustic pressure wave. The QC laser was modulated at the resonant frequency of the tuning fork (32.8 kHz) and delivered a modest 5.3 mW at the tuning fork. This spectrometer was calibrated using the infrared absorber Freon-134a by performing a simultaneous absorption measurement using a 35 cm absorption cell. The NEAS of this instrument was determined to be 2 x 10{sup -8} W cm-1 Hz{sup -1/2}. A corresponding theoretical analysis of the instrument sensitivity is presented and is capable of quantitatively reproducing the experimental NEAS, indicating that the fundamental sensitivity of this technique is limited by the noise floor of the tuning fork itself.

YAG laser-induced structural modification in transition metal ion containing 40K{sub 2}O-40Nb{sub 2}O{sub 5}-20SiO{sub 2} glasses  

SciTech Connect

Glasses with the compositions of 40K{sub 2}O-40Nb{sub 2}O{sub 5}-20SiO{sub 2} (in mol%) containing different concentrations (0.01, 1 and 2 mol%) of NiO were prepared by a melt quenching technique. The glasses were irradiated with a continuous wave Nd:YAG laser with a wavelength of 1064 nm, and a metastable crystalline phase of KNbO{sub 3} was obtained. In 2 mol% NiO-doped glass, lines with a width of {approx}10 {mu}m are successfully patterned by laser irradiations with a power of 0.9 W and a scanning speed of 15 {mu}m/s. It is found from micro-Raman scattering spectra that the lines are composed of the metastable crystalline phase of KNbO{sub 3}. The crystallization mechanism in Nd:YAG laser-induced crystallization in the glasses is discussed in comparison with the usual crystallization in an electric furnace.

Structural and Spectroscopic Characterization of 17- and 18-Electron Piano-Stool Complexes of Chromium. Thermochemical Analyses of Weak Cr-H Bonds  

SciTech Connect

The 17-electron radical CpCr(CO)2(IMe)• (IMe = 1,3-dimethylimidazol-2-ylidene) was synthesized by the reaction of IMe with [CpCr(CO)3]2, and characterized by single crystal X-ray diffraction and by EPR, IR and variable temperature 1H NMR spectroscopy. The metal-centered radical is monomeric under all conditions and exhibits Curie paramagnetic behavior in solution. An electrochemically reversible reduction to 18-electron CpCr(CO)2(IMe)? takes place at E½ = ?1.89(1) V vs Cp2Fe+•/0 in MeCN, and was accomplished chemically with KC8 in THF. The salts K+(18-crown-6)[CpCr(CO)2(IMe)]? • ½THF and K+[CpCr(CO)2(IMe)]? • ¾THF were crystallographically characterized. Monomeric ion pairs are found in the former, whereas the latter has a polymeric structure due to a network of K???O(CO) interactions. Protonation of K+(18-crown-6)[CpCr(CO)2(IMe)]? • ½THF gives the hydride CpCr(CO)2(IMe)H, which could not be isolated, but was characterized in solution; a pKa of 27.2(4) was determined in MeCN. A thermochemical analysis provides the Cr-H bond dissociation free energy (BDFE) for CpCr(CO)2(IMe)H in MeCN solution as 47.3(6) kcal mol?1. This value is exceptionally low for a transition metal hydride, and implies that the reaction 2 [Cr-H] ? 2 [Cr•] + H2 is exergonic (?G = ?9.0(8) kcal mol?1). This analysis explains the experimental observation that generated solutions of the hydride produce CpCr(CO)2(IMe)• (typically on the timescale of days). By contrast, CpCr(CO)2(PCy3)H has a higher Cr-H BDFE (52.9(4) kcal mol?1), is more stable with respect to H2 loss, and is isolable.

Enthalpy of formation and magnetic susceptibility of curium sesquioxide, Cm/sub 2/O/sub 3/  

SciTech Connect

Monoclinic Cm/sub 2/O/sub 3/ has been prepared from the long-lived isotope /sup 248/Cm (t/sub 1///sub 2/ = 3.4 x 10/sup 5/ y), and its enthalpy of formation has been determined at 298 K to be -1682 +/- 12 kJ mol/sup -1/ from solution calorimetry measurements on four different samples. The magnetic susceptibility of three of these samples has been measured on a Faraday balance between 2 and 298 K. Cm/sub 2/O/sub 3/ exhibits Curie-Weiss behavior from 100 to 300 K with ..mu../sub eff/ = 7.89 +/- 0.04 ..mu../sub B/ and THETA = -130 +/- 2 K. The compound appears to order magnetically as the temperature decreases and has an antiferromagnetic transition at 13 +/- 2 K. The results are interpreted by comparison with similar properties of related lanthanide and actinide compounds.

Syngas production from glycerol-dry(CO2) reforming over La-promoted Ni/Al2O3 catalyst  

Science Journals Connector (OSTI)

Abstract A 3 wt% La-promoted Ni/Al2O3 catalyst was prepared via wet co-impregnation technique and physicochemically-characterized. Lanthanum was responsible for better metal dispersion; hence higher BET specific surface area (96.0 m2 g?1) as compared to the unpromoted Ni/Al2O3 catalyst (85.0 m2 g?1). In addition, the La-promoted catalyst possessed finer crystallite size (9.1 nm) whilst the unpromoted catalyst measured 12.8 nm. Subsequently, glycerol dry reforming was performed at atmospheric pressure and temperatures ranging from 923 to 1123 K employing CO2-to-glycerol ratio from zero to five. Significantly, the reaction results have yielded syngas as main gaseous products with H2:CO ratios always below than 2.0 with concomitant maximum 96% glycerol conversion obtained at the CO2-to-glycerol ratio of 1.67. In addition, the glycerol consumption rate can be adequately captured using power law modelling with the order of reactions equal 0.72 and 0.14 with respect to glycerol and CO2 whilst the activation energy was 35.0 kJ mol?1. A 72 h longevity run moreover revealed that the catalyst gave a stable catalytic performance.

PdZnAl Catalysts for the Reactions of Water-Gas-Shift, Methanol Steam Reforming, and Reverse-Water-Gas-Shift  

SciTech Connect

Pd/ZnO/Al2O3 catalysts were studied for water-gas-shift (WGS), methanol steam reforming, and reverse-water-gas-shift (RWGS) reactions. WGS activity was found to be dependent on the Pd:Zn ratio with a maximum activity obtained at approximately 0.50, which was comparable to that of a commercial Pt-based catalyst. The catalyst stability was demonstrated for 100 hours time-on-stream at a temperature of 3600C without evidence of metal sintering. WGS reaction rates were approximately 1st order with respect to CO concentration, and kinetic parameters were determined to be Ea = 58.3 kJ mol-1 and k0 = 6.1x107 min-1. During methanol steam reforming, the CO selectivities were observed to be lower than the calculated equilibrium values over a range of temperatures and steam/carbon ratios studied while the reaction rate constants were approximately of the same magnitude for both WGS and methanol steam reforming. These results indicate that although Pd/ZnO/Al2O3 are active WGS catalysts, WGS is not involved in methanol steam reforming. RWGS rate constants are on the order of about 20 times lower than that of methanol steam reforming, suggesting that RWGS reaction could be one of the sources for small amount of CO formation in methanol steam reforming.

Synthesis and characterization of thermoplastic polyurethane/nanoclay composites  

Science Journals Connector (OSTI)

In this study thermoplastic polyurethane (TPU) composites were obtained with different nanoclay contents (0, 1, 3 for all cases and 10 wt.% in some cases). The nanoclay Cloisite®30B (C30B) was dispersed in the TPU matrix by melt processing (twin-screw extruder; TPU-E composites) and during bulk polymerization (TPU-S composites). The synthesis method involved the two-step bulk polymerization of polyesterpolyol (molecular weight 2000 g mol1) and diphenylmethanediisocyanate (MDI) with 1,4-butanediol as the chain extender. The dispersion state of the nanoclay particles and its effect on the mechanical properties of the composites, before and after ageing, was investigated. The characterization of TPU/nanoclay composites was carried out by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The mechanical characterization was performed through determination of the tensile and tear strengths. The TPU-E 3 wt.% composite showed the best improvement with increases in stress and strain at break (28% and 35%, respectively) and energy (88%), compared to the TPU-E (sample without nanoclay).

Nanostructured F doped IrO2 electro-catalyst powders for PEM based water electrolysis  

Science Journals Connector (OSTI)

Abstract Fluorine doped iridium oxide (IrO2:F) powders with varying F content ranging from 0 to 20 wt.% has been synthesized by using a modification of the Adams fusion method. The precursors (IrCl4 and NH4F) are mixed with NaNO3 and heated to elevated temperatures to form high surface area nanomaterials as electro-catalysts for PEM based water electrolysis. The catalysts were then coated on a porous Ti substrate and have been studied for the oxygen evolution reaction in PEM based water electrolysis. The IrO2:F with an optimum composition of IrO2:10 wt.% F shows remarkably superior electrochemical activity and chemical stability compared to pure IrO2. The results have also been supported via kinetic studies by conducting rotating disk electrode (RDE) experiments. The RDE studies confirm that the electro-catalysts follow the two electron transfer reaction for electrolysis with calculated activation energy of ?25 kJ mol?1. Single full cell tests conducted also validate the superior electrochemical activity of the 10 wt.% F doped IrO2.

Groundwater remediation by anionic surfactant micelles — An innovative double layer model applied to Na+ and Mg2+ association with dodecylsulfate micelles  

Science Journals Connector (OSTI)

The association reactions involving counterions, Na+ and Mg2+, and micelles composed of the anionic surfactant, dodecylsulfate (DS?), were investigated in ultrafiltration experiments. To access the data, an innovative model was developed that considered specific counterion binding within a Stern layer, with binding constant dependent upon the electrical potential as derived by the Poisson-Boltzmann equation and with calculation of the cmc as a function of counterion binding (or association). The experimental and model results both show that magnitude of counterion binding is greater for divalent species, Mg2+, than that for the monovalent species, Na2+. However, high concentration of Na+ compete for surface area diminishing the ability of the DS? to bind either divalent species. At experimental conditions from 0 to 100 mM NaCI addition, the binding ratio (BR) varied only from 0.58 to 0.63. The optimum binding constants, \\{KMg\\} and KNa, were determined to be 0.4 and 1.0 L mol?1, respectively, for the model. The experimental data and model calculated results were generally in good agreement.

Combined molten salt–Ni/Al2O3 as synergistic medium for high-quality syngas production  

Science Journals Connector (OSTI)

Abstract Proposed synergistic use of a combined medium of molten salt and Ni/Al2O3 (MS-Ni) was investigated for its enhancement of cellulose pyrolysis for high-quality syngas production. Clean renewable solar energy is to be stored at a high temperature in molten salt (MS) and provides the heat of pyrolysis. The MS-Ni medium could increase H2 yield by 3-folds while CO yield slightly increased by 15%, compared to the case of only MS medium. The peak rate of H2 production nearly quadrupled while the peak rate of CO production increased 2.5 times at about 150 and 80 K lower temperatures, respectively. The ratio of selectivity of syngas to undesired CH4 was nearly doubled. Arrhenius rate expressions for pseudo-first-order pyrolytic reaction are derived from the experimental data to give activation energies of 206 and 128 kJ mol?1 for the MS and the MS-Ni mediums, respectively. The experimental results clearly validated the role of MS-Ni as a synergistic medium for high-quality syngas production from cellulosic biomass pyrolysis.

New nickel-based material (Sr12Al14O33) for biomass tar steam reforming for syngas production  

Science Journals Connector (OSTI)

A new “free oxygen” material Sr12Al14O33 (Sr12A7) was developed as a Ni support for biomass tar steam reforming. Toluene was chosen as the model compound for biomass gasification tar. The steam reforming process was investigated in a fixed-bed reactor. The influence of the operating parameters (i.e. reaction temperature steam-to-carbon ratio and space time) on catalyst activity and product selectivity were studied. Ni/Sr12A7 (5?wt %) showed a higher activity compared with a similar commercial catalyst Ni/Dolomite. The influence of the steam/carbon (S/C) molar ratio on gas yields at values ranging from 1.5 to 4.0 was investigated. The results show that the H2 and CO2 yields increased whereas the CO yield decreased when the S/C ratio was increased. The influence of space-time (w cat/F toluene) was also determined. The H2 CO2 and total gas yields increased when the ratio was increased. Catalyst ageing experiments were characterized by Brunauer-Emmett-Teller (BET) X-ray diffraction (XRD) and energy dispersive X-ray spectrometer (EDX). Based on the results the kinetic model is proposed as a first-order reaction for toluene with an activation energy of 131.2?kJ·mol?1 as generally accepted in the literature.

Mechanism of 1-(1-propylsulfonic)-3-methylimidazolium chloride catalyzed transformation of d-glucose to 5-hydroxymethylfurfural in DMSO: an NMR study  

Science Journals Connector (OSTI)

Abstract The conversion of d-glucose to 5-hydroxymethylfurfural (HMF) in the presence of 5.48 mol % 1-(1-propylsulfonic)-3-methylimidazolium chloride acidic ionic liquid catalyst in DMSO at 150 °C was studied using 1H, 13C NMR, and visible spectroscopy. The HMF yield rapidly increases in the first 100 min of reaction, however yield drops beyond 100 min and levels off to a maximum yield of about 15.7% around 600 min. The visible spectroscopy study of the reaction mixture suggests that rate of HMF formation slows down after 100 min due to increase in the rate of humin formation after first 100 min. A mechanism has been proposed and key intermediates in the pathway could be identified by studying the 13C NMR spectra of acidic ionic liquid catalyzed transformations of C-1 and C-2 13C labeled d-glucose under identical conditions. The proposed mechanism involves the isomerization of d-glucose to d-fructose via the complexation of the open chain sugar with the imidazolium cation of the acidic ionic liquid catalyst.

Synthesis, Characterization, Photophysics and Photochemistry of Pyrylogen Electron Transfer Sensitizers  

SciTech Connect

A series of new dicationic sensitizers that are hybrids of pyrylium salts and viologens has been synthesized. The electrochemical and photophysical properties of these "pyrylogen" sensitizers are reported in sufficient detail to allow rationale design of new photoinduced electron transfer reactions. The range of their reduction potentials (+0.37-+0.05V vs SCE) coupled with their range of singlet (48-63 kcal mol(-1)) and triplet (48-57kcalmol(-1)) energies demonstrate that they are potent oxidizing agents in both their singlet and triplet excited states, thermodynamically capable of oxidizing substrates with oxidation potentials as high as 3.1eV. The pyrylogens are synthesized in three steps from readily available starting materials in modest overall 11.4-22.3% yields. These sensitizers have the added advantages that: (1) their radical cations do not react on the CV timescale with oxygen bypassing the need to run reactions under nitrogen or argon and (2) have long wavelength absorptions between 413 and 523nm well out of the range where competitive absorbance by most substrates would cause a problem. These new sensitizers do react with water requiring special precautions to operate in a dry reaction environment.

Photomagnetic Switching of the Complex [Nd(dmf)[subscript 4](H[subscript 2]O)[subscript 3]([mu]-CN)Fe(CN)[subscript 5  

SciTech Connect

Single-crystal XRD experiments (see picture) reveal the excited-state structure of the photomagnetic heterobimetallic title complex. The system shows a decrease in all the iron-ligand bond lengths, suggesting that photoexcitation involves a ligand-to-metal charge transfer or a change in the superexchange coupling between the metal centers.

Er{sup 3+}-doped strontium lithium bismuth borate glasses for broadband 1.5 {mu}m emission - optical properties  

SciTech Connect

Strontium lithium bismuth borate glasses (SLBiB) doped with various concentrations of Er{sup 3+} were prepared using conventional melt quench technique and investigated their optical properties. The amorphous nature of the prepared glass samples was confirmed by X-ray diffraction and SEM analysis. Optical properties were studied by measuring the optical absorption and near infrared luminescence spectra at room temperature. Judd-Ofelt (J-O) theory has been applied for the f.f transitions of Er{sup 3+} ions to evaluate J-O intensity parameters, {Omega}{lambda} ({lambda} = 2, 4 and 6). Using the J-O intensity parameters, radiative properties such as transition probabilities (A{sub R}), branching ratios ({beta}) and radiative lifetimes ({tau}) are estimated for certain transitions. From the emission spectra, peak emission-cross sections ({sigma}{sub p}) and products of stimulated emission cross-section and full width at half maximum ({sigma}{sub p} Multiplication-Sign FWHM) were calculated for the observed emission transition, {sup 4}I{sub 13/2}{yields}{sup 4}I{sub 15/2}.

Hyperfine dependent $gf$-values of Mn I lines in the 1.49 $-$ 1.80 $\\mu$m H-band  

E-Print Network (OSTI)

The three Mn I lines at 17325, 17339 and 17349 \\AA~are among the 25 strongest lines ($\\log(gf)>0.5$) in the H-band. They are all heavily broadened due to hyperfine structure and the profiles of these lines have so far not been understood. Earlier studies of these lines even suggested that they were blended. In this work, the profiles of these three infra-red (IR) lines have been studied theoretically and compared to experimental spectra to assist in the complete understanding of the solar spectrum in the IR. It is shown that the structure of these lines can not be described in the conventional way by the diagonal $A$ and $B$ hyperfine interaction constants. The off-diagonal hyperfine interaction not only has large impact on the energies of the hyperfine levels, but also introduces a large intensity redistribution among the hyperfine lines, changing the line profiles dramatically. By performing large-scale calculations of the diagonal and off-diagonal hyperfine interaction and $gf$-values between the upper and...

Flow stress of oxygen-enriched Zircaloy-2 between 1023 and 1873 K  

SciTech Connect

The solute strengthening effect of oxygen in commercial-purity Zircaloy-2 was investigated over the temperature range 1023 to 1873 K, strain rate range 10/sup -4/ to 10/sup -1/s/sup -1/, and oxygen concentration range 1260 to 12 360ppm. The flow parameters were determined in the fully ..cap alpha.. and fully ..beta.. as well as (..cap alpha.. + ..beta..) phase domains. In the two-phase region, the flow curves were characterized by significant yield drops as long as the ..beta.. volume fraction was over about 50 percent. This effect is ascribed to the enrichment of the ..beta..-phase in the subsitutional solutes iron and possibly chromium. The flow curves were otherwise normal. For the single-phase ..cap alpha.. and ..beta.. structures, the yield and steady-state stresses obeyed the general relation sigma=sigma/sub 0/ exp (kc), where sigma/sub 0/ and k are constants, and c represents the oxygen concentration (weight percent). The average values of k/sub ..cap alpha../ and k/sub ..beta../ were determined to be 0.57+/-0.16 and 0.34+/-0.10, respectively. The strain rate sensitivities fell in the following ranges, depending on the phases present: 0.15 to 0.20, 0.27 to 0.32, and 0.22 to 0.25 for the ..cap alpha.., ..beta.., and (..cap alpha.. + ..beta..) materials, respectively. The experimental activation energies decreased with stress in the ranges 450 to 330 kJ/mol(50 to 150 MPa) and 150 to 120kJ/mol(1 to 5 MPa) for the ..cap alpha..- and ..beta..-Zircaloy-2, respectively. The extrapolated zero stress values of Q were 530 and 170kJ/mol, and are associated with the dominant dynamic recovery mechanism in each phase. The observed steady-state as well as yield stresses correspond closely to the rule-of-mixture predictions but lie considerably above the values interpolated from the fully ..cap alpha..-phase and fully ..beta..-phase. This is ascribed to the very powerful strengthening effect of oxygen on the ..cap alpha..-phase when it is enriched during the formation of two phases from either single-phase region.

Science Journals Connector (OSTI)

A novel conjugation-elongated bis(ethylenedithio)tetraselenafulvalene (BETS) type donor, 2,5-bis(4,5-ethylenedithio-1,3-diselenol-2-ylidene)-2,3,4,5-tetrahydrothiophene (BEDT-HBDST) and its magnetic and non-magnetic anion salts, (BEDT-HBDST)2MX4 (MX4?=FeCl4?, GaCl4?, FeBr4? and GaBr4?), were prepared. These four salts are isostructural and belong to the space group of P2/c. They showed semiconducting behavior with small activation energies (59–64 meV). The band structures of these salts are quasi one-dimensional and there is a midgap between the upper band and the lower band, since the degree of dimerization is significant in the stacking direction. The MX4? ions are located between the donor columns and near to the ethylenedithio moieties of the donor molecules. The magnetic susceptibilities of the FeCl4? and FeBr4? salts follow the Curie–Weiss law with Curie constants of 4.6 and 4.8 emu K mol?1 (sum of the spins of S=5/2 and S=1/2) and negative Weiss temperatures of ?=?1.2 and ?4.9 K, respectively, revealing a weak antiferromagnetic interaction of 3d spins of the FeCl4? and FeBr4? anions. The Fe?Fe (6.66–7.60 Å), Cl?Cl (4.81–4.82 Å) and Br?Br (4.74–4.77 Å) distances in the crystal structures of these salts are significantly long. Therefore, the direct magnetic interaction between the 3d spins of the nearest neighboring Fe3+ ions appears to be not readily accessible.

Kinetics and PEMFC performance of RuxMoySez nanoparticles as a cathode catalyst  

Science Journals Connector (OSTI)

Kinetics of RuxMoySez nanoparticles dispersed on carbon powder was studied in 0.5 M H2SO4 electrolyte towards the oxygen reduction reaction (ORR) and as cathode catalysts for a proton exchange membrane fuel cell (PEMFC). RuxMoySez catalyst was synthesized by decarbonylation of transition-metal carbonyl compounds for 3 h in organic solvent. The powder was characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques. Catalyst is composed of uniform agglomerates of nanocrystalline particles with an estimated composition of Ru6Mo1Se3, embedded in an amorphous phase. The electrochemical activity was studied by rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) techniques. Tafel slopes for the ORR remain invariant with temperature at ?0.116 V dec?1 with an increase of the charge transfer coefficient in d?/dT = 1.6 × 10?3, attributed to an entropy turnover contribution to the electrocatalytic reaction. The effect of temperature on the ORR kinetics was analyzed resulting in an apparent activation energy of 45.6 ± 0.5 kJ mol?1. The catalyst generates less than 2.5% hydrogen peroxide during oxygen reduction. The RuxMoySez nanoparticles dispersed on a carbon powder were tested as cathode electrocatalyst in a single fuel cell. The membrane-electrode assembly (MEA), included Nafion® 112 as polymer electrolyte membrane and commercial carbon supported Pt (10 wt%Pt/C-Etek) as anode catalyst. It was found that the maximum performance achieved for the electro-reduction of oxygen was with a loading of 1.0 mg cm?2 RuxMoySez 20 wt%/C, arriving to a power density of 240 mW cm?2 at 0.3 V and 80 °C.

Zusammenfassung Bei der Photolyse (? = 185 nm) von flüssigem Methanol entstehen Wasserstoff, Glykol, Formaldehyd und Methan sowie Spuren Äthan. Die Quantenausbeuten (bezogen auf ?(H2) = 0·4 des Äthanol -Aktinometers (5 mol/1 in Wasser)) betragen 0·83, 0·78, 0·058, 0·05 bzw. 0·002. Die Isotopenverteilung des bei der Photolyse von CH3OD entstehenden Wasserstoffs (85% HD) zeigt, dass in der flüssigen Phase, ähnlich wie in der Gasphase,2 die Spaltung der O?H-Bindung (1) der wichtigste Zerfallsprozess ist.

CH3O• + H• (1) In Mischungen mit Wasser, in denen das Wasser fast keinen Anteil der Strahlung absorbiert, werden die Quantenausbeuten der Produkte Wasserstoff, Glykol, Methan und Äthan stark erniedrigt, während die Formaldehydausbeute konstant bleibt. In 1 molarer Lösung beträgt ?(H2) = 0·42, ?(Glykol) = 0·32, ?(CH4) = 6·10?4. Äthan ist nicht mehr nachweisbar. The UV photolysis (? = 185 nm) of liquid methanol yields hydrogen, glycol, formaldehyde, methane and traces of ethane in quantum yields of 0·83, 0·78, 0·058, 0·05 and 0·002 resp. (related to ?(H2) = 0·4 of the ethanol-actinometer (5 mole/1 in water)). The isotopic distribution of the hydrogen (85% HD) formed in the photolysis of CH3OD shows, that as in the gasphase2 the scission of the O?H-bond (1) is the major process. CH3OH + hv (? = 185 nm) ? CH3O• + H• (1) In methanoi-water mixtures (nearly all the light of the wavelength ? = 185 nm is absorbed by methanol) the quantum yields of hydrogen, glycol, methane and ethane are greatly reduced, while the formaldehyde yield remains unaffected. In 1 molar solution ?(H2) = 0·42, ?(glycol) = 0·32 and ?(CH4) = 6 x 10?4 is obtained. Ethane cannot be detected.

Mechanistic Examination of C?–C? Bond Cleavages of Tryptophan Residues during Dissociations of Molecular Peptide Radical Cations  

SciTech Connect

In this study, we used collision-induced dissociation (CID) to examine the gas-phase fragmentations of [GnW]•+ (n = 2-4) and [GXW]•+ (X = C, S, L, F, Y, Q) species. The C?–C? bond cleavage of a C-terminal decarboxylated tryptophan residue ([M - CO2]•+) can generate [M - CO2 - 116]+, [M - CO2 - 117]•+, and [1H-indole]•+ (m/z 117) species as possible product ions. Competition between the formation of [M - CO2 - 116]+ and [1H-indole]•+ systems implies the existence of a proton-bound dimer formed between the indole ring and peptide backbone. Formation of such a proton-bound dimer is facile via a protonation of the tryptophan ?-carbon atom as suggested by density functional theory (DFT) calculations. DFT calculations also suggested the initially formed ion 2--the decarboxylated species that is active against C?–C? bond cleavage -can efficiently isomerize to form a more-stable -radical isomer (ion 9) as supported by Rice-Ramsperger-Kassel-Marcus (RRKM) modeling. The C?–C? bond cleavage of a tryptophan residue also can occur directly from peptide radical cations containing a basic residue. CID of [WGnR]•+ (n = 1-3) radical cations consistently resulted in predominant formation of [M-116]+ product ions. It appears that the basic arginine residue tightly sequesters the proton and allows the charge-remote C?–C? bond cleavage to prevail over the charge-directed one. DFT calculations predicted the barrier for the former is 6.2 kcal mol -1 lower than that of the latter. Furthermore, the pathway involving a salt-bridge intermediate also was accessible during such a bond cleavage event.

Zeolite-promoted transformation of glucose into 5-hydroxymethylfurfural in ionic liquid  

Science Journals Connector (OSTI)

Abstract A variety of zeolite catalysts were investigated for the conversion of glucose into 5-hydroxymethylfurfural (HMF) in ionic liquid 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), and the results revealed that H?-zeolite with a unique BEA structure and a moderate Si/Al ratio of 25 possessed the highest catalytic activity, which resulted in 50.3% HMF yield with 80.6% glucose conversion at a reaction temperature of 150 °C for only 50 min. In the presence of H?-zeolite (Si/Al = 25) and [BMIM]Cl, the reaction kinetics for the conversion of glucose into HMF was studied and determined to be in accordance with a first-order reaction rate equation, and the activation energy and pre-exponential factor were 97.4 kJ mol?1 and 2.2 × 1010 min?1, respectively. Moreover, a plausible mechanism involving the isomerization of glucose into fructose followed by the dehydration of fructose into HMF was proposed on the basis of the synergistic catalytic effect between Lewis acid sites and Brønsted acid sites of H?-zeolite. H?-zeolite (Si/Al = 25) could be easily regenerated via a simple calcination, and a similar HMF yield with the first reaction run was observed in the seventh reaction run. More importantly, H?-zeolite (Si/Al = 25) and [BMIM]Cl were also confirmed to be an excellent combination for the conversion of other carbohydrates such as fructose, sucrose, maltose, cellobiose, starch and cellulose into HMF.

With anionic surfactant LAS assisted, series of zinc cadmium sulfide semiconductor photocatalysts were synthesized by hydrothermal method. These products were characterized by X-ray diffraction (XRD), UV-Vis absorption spectra (UV-Vis) and scanning electron microscopy (FESEM). The photocatalytic activities of as-prepared samples were evaluated by photocatalytic hydrogen production from water under visible-light irradiation. The best synthesis parameters are: Composition 0.9:0.1 (Cd:Zn molar ratio), Temperature 160 deg. C, Hydrothermal Time 48 Hour, LAS Concentration 1.7 mmol/L, the maximum visible-light-catalytic hydrogen production rate is 161.25 {mu}mol/h (lambda>430 nm) which is higher than those of by coprecipitation method. The experiment results indicate that surfactant assisted hydrothermal method is an effective way to get highly active CdZnS solid solution photocatalyst.

Arsenic remediation of drinking water using iron-oxide coated coal bottom ash  

SciTech Connect

We describe laboratory and field results of a novel arsenic removal adsorbent called 'Arsenic Removal Using Bottom Ash' (ARUBA). ARUBA is prepared by coating particles of coal bottom ash, a waste material from coal fired power plants, with iron (hydr)oxide. The coating process is simple and conducted at room temperature and atmospheric pressure. Material costs for ARUBA are estimated to be low (~;;$0.08 per kg) and arsenic remediation with ARUBA has the potential to be affordable to resource-constrained communities. ARUBA is used for removing arsenic via a dispersal-and-removal process, and we envision that ARUBA would be used in community-scale water treatment centers. We show that ARUBA is able to reduce arsenic concentrations in contaminated Bangladesh groundwater to below the Bangladesh standard of 50 ppb. Using the Langmuir isotherm (R2 = 0.77) ARUBA's adsorption capacity in treating real groundwater is 2.6x10-6 mol/g (0.20 mg/g). Time-to-90percent (defined as the time interval for ARUBA to remove 90percent of the total amount of arsenic that is removed at equilibrium) is less than one hour. Reaction rates (pseudo-second-order kinetic model, R2>_ 0.99) increase from 2.4x105 to 7.2x105 g mol-1 min-1 as the groundwater arsenic concentration decreases from 560 to 170 ppb. We show that ARUBA's arsenic adsorption density (AAD), defined as the milligrams of arsenic removed at equilibrium per gram of ARUBA added, is linearly dependent on the initial arsenic concentration of the groundwater sample, for initial arsenic concentrations of up to 1600 ppb and an ARUBA dose of 4.0 g/L. This makes it easy to determine the amount of ARUBA required to treat a groundwater source when its arsenic concentration is known and less than 1600 ppb. Storing contaminated groundwater for two to three days before treatment is seen to significantly increase ARUBA's AAD. ARUBA can be separated from treated water by coagulation and clarification, which is expected to be less expensive than filtration of micron-scale particles, further contributing to the affordability of a community-scale water treatment center.

Complete oxidation of CO, ethanol, and ethyl acetate over copper oxide supported on titania and ceria modified titania  

SciTech Connect

Titania and titania modified with 3 and 12 {mu}mol Ce/m{sup 2} surface area of the titania were prepared and were used as supports for copper oxide. Preparations with 3 and 12 {mu}mol CuO{sub x}/m{sup 2} surface area of the support were tested for the combustion of CO, ethyl acetate, and ethanol. The results show that the Ce-doped titania surface is good as support for CuO{sub x} and that the cerium not only enhances the activity of the copper species, but also stabilizes the surface area of the TiO{sub 2} support in the presence of copper oxide. Additions of Al, K, and La are also found to stabilize the TiO{sub 2} support but, compared with Ce, these elements do not to the same extent enhance the activity of the copper species. Acetaldehyde is observed to ban an intermediate in the combustion of both ethanol and ethyl acetate over Cu-Ce-Ti-O catalysts. Since acetaldehyde is more harmful than any of the reactants and also is photochemically active, it is in applications important to assure that the combustion is complete. Cu-Ce-Ti-O catalysts show good performance not only for feeds without water vapor, but also for humid feeds. Although the concentrations of intermediates are affected by the addition of water, there is little effect on the temperature required for obtaining complete conversion to carbon dioxide and water. Characterization with XRD, FT-Raman, TPR, and XPS indicates that the dispersed copper species are in the form of patches or a bidimensional layer which interacts with the surface of the support. When the content of cerium and copper is low, other types of dispersed copper species are present, which possibly are monomers or dimers. The copper species are predominantly Cu{sup 2+} species.

Synthesis, structure and magnetic properties of La{sub 3}Co{sub 2}SbO{sub 9}: A double perovskite with competing antiferromagnetic and ferromagnetic interactions  

SciTech Connect

The synthesis, structural characterization, and magnetic properties of La{sub 3}Co{sub 2}SbO{sub 9} double perovskite are reported. The crystal structure has been refined by X-ray and neutron powder diffraction data in the monoclinic space group P2{sub 1}/n. Co{sup 2+} and Sb{sup 5+} have the maximum order allowed for the La{sub 3}Co{sub 2}SbO{sub 9} stoichiometry. Rietveld refinements of powder neutron diffraction data show that at room temperature the cell parameters are a=5.6274(2) A, b=5.6842(2) A, c=7.9748(2) A and {beta}=89.999(3) Degree-Sign . Magnetization measurements indicate the presence of ferromagnetic correlations with T{sub C}=55 K attributed to the exchange interactions for non-linear Co{sup 2+}-O-Sb{sup 5+}-O-Co{sup 2+} paths. The effective magnetic moment obtained experimentally is {mu}{sub exp}=4.38 {mu}{sub B} (per mol Co{sup 2+}), between the theoretical one for spin only (3.87 {mu}{sub B}) and spin-orbit value (6.63 {mu}{sub B}), indicating partially unquenched contribution. The low magnetization value at high magnetic field and low temperature (1 {mu}{sub B}/f.u., 5 T and 5 K) and the difference between ZFC and FC magnetization curves (at 5 kOe) indicate that the ferromagnetism do not reach a long range order and that the material has an important magnetic frustration. - Graphical abstract: Co-O-Co (Yellow octahedra only) rich zones (antiferromagnetic) are in contact with Co-O-Sb-O-Co (Red and yellow octahedra) rich zones (Ferromagnetic) to give the peculiar magnetic properties, as a consequence, a complex hysteresis loop can be observed composed by a main and irreversible curve in all the measured range, superimposed with a ferromagnetic component at low fields. Highlights: Black-Right-Pointing-Pointer La{sub 3}Co{sub 2}SbO{sub 9} has small Goldschmidt Tolerance Factor (t) due to the small size of La{sup 3+}. Black-Right-Pointing-Pointer Small t determines an angle for the path Co{sup 2+}-O-Sb{sup 5+}-O-Co{sup 2+} of 153 Degree-Sign . Black-Right-Pointing-Pointer Ferromagnetism is attributed to exchange interactions for Co{sup 2+}-O-Sb{sup 5+}-O-Co{sup 2+} paths.

Gas temperature profiles at different flow rates and heating rates suffice to estimate kinetic parameters for fluidised bed combustion  

SciTech Connect

Experimental work on estimation kinetic parameters for combustion was conducted in a bench-scale fluidised bed (FB: 105x200mm). Combustion medium was obtained by using an electrical heater immersed into the bed. The ratio of heating rate (kJ/s) to molar flow rate of air (mol/s) regulated by a rheostat so that the heat of combustion (kJ/mol) can be synthetically obtained by an electrical power supply for relevant O{sub 2}-feedstock concentration (C{sub 0}). O{sub 2}-restriction ratio ({beta}) was defined by the ratio of O{sub 2}-feedstock concentration to O{sub 2}-air concentration (C{sub O{sub 2}-AIR}) at prevailing heating rates. Compressed air at further atmospheric pressure ({approx_equal}102.7kPa) entered the bed that was alumina particles (250{mu}m). Experiments were carried out at different gas flow rates and heating rates. FB was operated with a single charge of (1300g) particles for obtaining the T/T{sub 0} curves, and than C/C{sub 0} curves. The mathematical relationships between temperature (T) and conversion ratio (X) were expressed by combining total energy balance and mass balance in FB. Observed surface reaction rate constants (k{sub S}) was obtained from the combined balances and proposed model was also tested for these kinetic parameters (frequency factor: k{sub 0}, activation energy: E{sub A}, and reaction order: n) obtained from air temperature measurements. It was found that the model curves allow a good description of the experimental data. Thus, reaction rate for combustion was sufficiently expressed. (author)

Writing of nonlinear optical Sm{sub 2}(MoO{sub 4}){sub 3} crystal lines at the surface of glass by samarium atom heat processing  

SciTech Connect

Some glasses such as 21.25Sm{sub 2}O{sub 3}.63.75MoO{sub 3}.15B{sub 2}O{sub 3} (mol %) giving the formation of nonlinear optical Sm{sub 2}(MoO{sub 4}){sub 3} crystals through conventional crystallization in an electric furnace and through continuous-wave Nd: yttrium aluminum garnet (YAG) laser (wavelength: 1064 nm) irradiation (samarium atom heat processing) have been developed. It is proposed from x-ray diffraction analyses, micro-Raman-scattering spectra, and second-harmonic generation measurements that the crystal structure of Sm{sub 2}(MoO{sub 4}){sub 3} formed by the crystallization is the {beta}{sup '}-phase structure with an orthorhombic (noncentrosymmetric) symmetry. The lines consisting of nonlinear optical {beta}{sup '}-Sm{sub 2}(MoO{sub 4}){sub 3} crystals are written at the surface of glasses by YAG laser irradiation (laser power: P=0.4 W, laser scanning speed: S=1-10 {mu}m/s), and, in particular, homogeneous crystal lines are formed at the laser scanning speed of 1 {mu}m/s. Refractive index changes (not crystallization) are also induced by YAG laser irradiation of P=0.4 W and a high laser scanning speed of S=25 {mu}m/s. The crystallization mechanism in the laser-irradiated region has been proposed. The present study demonstrates that the samarium atom heat processing is a technique for the writing of rare earth containing optical nonlinear/ferroelectric crystal lines in glass.

SciTech Connect

New glasses giving the crystallization of Sm{sup 3+}-doped Sr {sub x} Ba{sub 1-} {sub x} Nb{sub 2}O{sub 6} (SBN) ferroelectrics have been developed in the Sm{sub 2}O{sub 3}-SrO-BaO-Nb{sub 2}O{sub 5}-B{sub 2}O{sub 3} system, and the formation of SBN crystal dots and lines by continuous wave Nd:YAG laser (wavelength:1064 nm, power: 1 W) irradiations, i.e., samarium atom heat processing, has been examined. The formation of Sm{sup 3+}-doped SBN non-linear optical crystals is confirmed from X-ray diffraction analyses, micro-Raman scattering spectra, second harmonic generations, and photoluminescence spectra. Sm{sup 3+}-doped SBN crystal dots with the diameters of 20-70 {mu}m and lines with the widths of 20-40 {mu}m are written at the surface of some glasses such as 10Sm{sub 2}O{sub 3}.10SrO.10BaO.20Nb{sub 2}O{sub 5}.50B{sub 2}O{sub 3} (mol%) by Nd:YAG laser irradiations with the irradiation times of 20-70 s for the dots and with the scanning speeds of 1-5 {mu}m/s for the lines. The present study suggests that the samarium atom heat processing has a potential for the patterning of optical waveguides consisting of ferroelectric SBN crystals in glass substrates.

On AgRhO{sub 2}, and the new quaternary delafossites AgLi{sub 1/3}M{sub 2/3}O{sub 2}, syntheses and analyses of real structures  

SciTech Connect

Two new quaternary delafossite type oxides with the general formula Ag(Li{sub 1/3}M{sub 2/3})O{sub 2}, M=Rh, Ir, have been synthesized, and their structures characterized. Based on X-ray and electron diffraction analyses the structural similarity with AgRhO{sub 2} delafossite, has been evidenced. The real structures of the quaternary delafossites have been revealed, which has allowed to fully explain the diffuse scattering as observed in X-ray powder diffraction. AgRhO{sub 2} is thermally stable up to 1173 K, the behavior of the two quaternary compounds AgLi{sub 1/3}Rh{sub 2/3}O{sub 2} and AgLi{sub 1/3}Ir{sub 2/3}O{sub 2} is comparable, and they decompose above 950 and 800 K, respectively. AgRhO{sub 2} shows temperature independent paramagnetism, while for the other two an effective magnetic moment of 1.77{mu}{sub B} for Ir, and 1.70{mu}{sub B} for Rh were determined, applying the Curie-Weiss law. All compounds are semiconducting with activation energies of 4.97 kJ mol{sup -1} (AgLi{sub 1/3}Rh{sub 2/3}O{sub 2}), 11.42 kJ mol{sup -1} (AgLi{sub 1/3}Ir{sub 2/3}O{sub 2}) and 17.58 kJ mol{sup -1} (AgRhO{sub 2}). -- graphical abstract: Two new quaternary delafossite type oxides with the general formula Ag(Li{sub 1/3}M{sub 2/3})O{sub 2}, M=Rh, Ir, have been synthesized, and their structures characterized.

Resolving the ?-effect in gas phase SN2 reactions: A Marcus theory approach  

Science Journals Connector (OSTI)

Recently we reported experimental validation of the ?-effect in the gas phase. However, an earlier study by our group showed a lack of enhanced reactivity in a series of SN2 reactions of ?-nucleophiles with methyl chloride conflicting with computational predictions. In an attempt to resolve these discrepancies, we investigate the SN2 reactions for methyl chloride of low exothermicity where the smaller thermodynamic component of the activation barrier may expose ?-nucleophilicity. The efficiencies for the reactions of several normal nucleophiles [C6H5O?, HC(O)O?, CH3C(O)O?] and alpha-nucleophiles [HC(O)OO?, CH3C(O)OO?] with \\{CH3Cl\\} are added to our previous Brønsted plot of normal and ?-nucleophile reactions with methyl chloride. While the presence of an ?-effect is suggested in some of the reactions with methyl chloride at lower basicities, the homologous properties of the “normal” ions in this region deviate from straight-chain alkoxides making the definition of “normal” reactivity more difficult. Application of Marcus theory provides insight into the intrinsic nature of the ?-effect and how easily intrinsic differences can be masked. Computational barriers were utilized to estimate an “average” Marcus intrinsic barrier for several reactions at two different levels of theory. The “average” intrinsic barrier for the identity reaction of HOO? lies roughly 15 kJ mol?1 below those of the “normal” nucleophiles, but this intrinsic difference is a maximum that can be significantly masked by leaving group barrier contributions to the overall Marcus activation barrier and thermodynamic driving forces. Variations in the intrinsic Marcus barriers of the anion(s) defining “normal” reactivity will play a key role in the magnitude of the ?-effect. Significantly lower electron affinities (?0.6 eV) are associated with the formation of the ?-oxyanions compared to the normal oxyanions (X + e? ? X?) suggesting that the ease of charge transfer between the nucleophile and transition state is responsible for the lower barriers of the ?-nucleophiles.

Carbon dioxide, hydrographic, and chemical data obtained in the Central South Pacific Ocean (WOCE sections P17S and P16S) during the tunes-2-expedition of the R/V Thomas Washington, July--August 1991  

SciTech Connect

This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO{sub 2}), discrete partial pressure of TCO{sub 2} (pCO{sub 2}), and total alkalinity (TALK), during the Research Vessel (R/V) Thomas Washington TUNES Leg 2 Expedition in the central South Pacific Ocean. Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Papeete, Tahiti, French Polynesia, on July 16, 1991, and returned to Papeete on August 25, 1991. WOCE Meridional Sections P17S along 135{degrees} W and P16S along 150{degrees} W were completed during the 40-day expedition. A total of 97 hydrographic stations were occupied. Hydrographic and chemical measurements made along WOCE Sections P17S and P16S included pressure, temperature, salinity, and oxygen measured by conductivity, temperature and depth sensor; bottle salinity; oxygen; phosphate; nitrate; nitrite; silicate; CFC-12; CFC- 11; TCO{sub 2}; TALK; and pCO{sub 2} measured at 20{degrees}C. The TCO{sub 2} concentration in 1000 seawater samples was determined with a coulometric analysis system, the pCO{sub 2} in 940 water samples was determined with an equilibrator/gas chromatograph system, while the TALK concentration in 139 samples was determined on shore at the laboratory of C. Goyet of Woods Hole Oceanographic Institution with an alkalinity titration system. In addition, 156 coulometric measurements for the Certified Reference Material (Batch {number_sign}6) were made and yielded a mean value of 2303.2 {plus_minus} 1.5 {mu}mol/kg. This mean value agrees within a standard deviation of the 2304.6 {plus_minus} 1.6 {mu}mol/kg (N=9) value determined with the manometer of C. D. Keeling at Scripps Institution of Oceanography (SIO). Replicate samples from 11 Niskin bottles at 4 stations were also collected for later shore-based reference analyses of TCO{sub 2} and TALK by vacuum extraction and manometry in the laboratory of C. D. Keeling of SIO.

Effects of genetic polymorphisms of metabolic enzymes on cytokinesis-block micronucleus in peripheral blood lymphocyte among coke-oven workers  

SciTech Connect

Exploring the associations between genetic polymorphisms of metabolic enzymes and susceptibility to polycyclic aromatic hydrocarbon (PAH)-induced chromosomal damage is of great significance for understanding PAH carcinogenesis. Cytochrome P450, glutathione S-transferase, microsomal epoxide hydrolase, NAD(P)H:quinone oxidoreductase, and N-acetyltransferase are PAH-metabolizing enzymes. In this study, we genotyped for the polymorphisms of these genes and assessed their effects on cytokinesis-block micronucleus (CBMN) frequencies in peripheral blood lymphocytes among 141 coke-oven workers and 66 non-coke-oven worker controls. The geometric means of urinary 1-hydroxypyrene levels in coke-oven workers and the controls were 12.0 and 0.7 {mu}mol/mol creatinine, respectively. The CBMN frequency (number of micronuclei per 1,000 binucleated lymphocytes) was significantly higher in coke-oven workers (9.5 {+-} 6.6) than in the controls. Among the coke-oven workers, age was positively associated with CBMN frequency; the mEH His{sup 113} variant genotype exhibited significantly lower CBMN frequency than did the Tyr{sup 113}/Tyr{sup 113} genotype; the low mEH activity phenotype exhibited a lower CBMN frequency than did the high mEH activity phenotype; the GSTP1 Val{sup 105}/Val{sup 105} genotype exhibited a higher CBMN frequency than did the GSTP1 Ile{sup 105}/Ile{sup 105} or Ile{sup 105}/Val{sup 105} genotypes; the joint effect of high mEH activity phenotype and GSTM1 null genotype on CBMN frequencies was also found. Gene-environment interactions between occupational PAH exposure and polymorphisms of mEH and/or GSTM1 were also evident. These results indicate that the mEH, GSTP1, and GSTM1 polymorphisms may play a role in sensitivity or genetic susceptibility to the genotoxic effects of PAH exposure in the coke-oven workers.

Thermodynamic and transport properties of single-crystal Yb{sub 14}MnSb{sub 11}  

SciTech Connect

Relatively large (up to 250 mg) single crystals of the intermetallic compound Yb{sub 14}MnSb{sub 11} have been prepared by a flux-growth technique. The results of thermodynamic and transport measurements of these samples are presented. The compound orders ferromagnetically at approximately T{sub C}=53{plus_minus}1K, with a magnetization consistent with the assignment Mn{sup 3+} (3d{sup 4}) and Yb{sup 2+} (4f{sup 14}). The Mn moments are local in nature, with the full effective and saturated moment of the Hund{close_quote}s rule spin-only ground state. The electrical resistivity has a metallic temperature dependence, with only a modest anisotropy. Room-temperature values of the resistivity are relatively high for an intermetallic compound: 1630{plus_minus}160 {mu}{Omega}cm and 1250{plus_minus}130 {mu}{Omega}cm for currents flowing approximately parallel and perpendicular to the {ital c} axis, respectively. There is a distinct loss of spin-disorder scattering in the resistivity at T{sub C}. From the heat capacity, a rough estimation of the magnetic entropy gives {Delta}S{sub M}{approx}12.1 J/mol K, the value in reasonable agreement with the expected {Delta}S{sub M}{approx}R ln 5 from the assignment of these moments. All of these data are consistent with a picture of Mn{sup 3+} local moments being coupled via conduction electrons. To this end, Yb{sub 14}MnSb{sub 11} appears to be analogous to local-moment rare-earth intermetallic compounds, and may point the way toward a class of 3d Kondo lattice compounds. {copyright} {ital 1999} {ital The American Physical Society}

Arsenic remediation of drinking water using iron-oxide coated coal bottom Arsenic remediation of drinking water using iron-oxide coated coal bottom ash Title Arsenic remediation of drinking water using iron-oxide coated coal bottom ash Publication Type Journal Article Year of Publication 2010 Authors Mathieu, Johanna L., Ashok J. Gadgil, Susan E. Addy, and Kristin Kowolik Journal Environmental Science and Health Keywords airflow and pollutant transport group, arsenic, bangladesh, coal bottom ash, drinking water, indoor environment department, water contaminants, water treatment Abstract We describe laboratory and field results of a novel arsenic removal adsorbent called 'Arsenic Removal Using Bottom Ash' (ARUBA). ARUBA is prepared by coating particles of coal bottom ash, a waste material from coal fired power plants, with iron (hydr)oxide. The coating process is simple and conducted at room temperature and atmospheric pressure. Material costs for ARUBA are estimated to be low (~$0.08 per kg) and arsenic remediation with ARUBA has the potential to be affordable to resource-constrained communities. ARUBA is used for removing arsenic via a dispersal-and-removal process, and we envision that ARUBA would be used in community-scale water treatment centers. We show that ARUBA is able to reduce arsenic concentrations in contaminated Bangladesh groundwater to below the Bangladesh standard of 50 ppb. Using the Langmuir isotherm (R2 = 0.77) ARUBA's adsorption capacity in treating real groundwater is 2.6×10-6 mol/g (0.20 mg/g). Time-to-90% (defined as the time interval for ARUBA to remove 90% of the total amount of arsenic that is removed at equilibrium) is less than one hour. Reaction rates (pseudo-second-order kinetic model, R2 ≥ 0.99) increase from 2.4×105 to 7.2×105 g mol-1 min-1 as the groundwater arsenic concentration decreases from 560 to 170 ppb. We show that ARUBA's arsenic adsorption density (AAD), defined as the milligrams of arsenic removed at equilibrium per gram of ARUBA added, is linearly dependent on the initial arsenic concentration of the groundwater sample, for initial arsenic concentrations of up to 1600 ppb and an ARUBA dose of 4.0 g/L. This makes it easy to determine the amount of ARUBA required to treat a groundwater source when its arsenic concentration is known and less than 1600 ppb. Storing contaminated groundwater for two to three days before treatment is seen to significantly increase ARUBA's AAD. ARUBA can be separated from treated water by coagulation and clarification, which is expected to be less expensive than filtration of micron-scale particles, further contributing to the affordability of a community-scale water treatment center

We have measured the magnetic susceptibility, specific heat, and electrical resistivity on single crystals of the intermetallic borocarbide YbNi{sub 2}B{sub 2}C. An enhanced linear contribution is observed in the specific heat with a Sommerfeld coefficient of 530 mJ/molK{sup 2}, indicative of a heavy-electron system with a Kondo temperature {approximately}10 K. The magnetic susceptibility, which is anisotropic and Curie-Weiss-like at high temperatures, is also consistent with our interpretation of a strongly correlated ground state at low temperatures and crystal-electric- field excitations at higher temperatures. At {ital T}=1.8 K, the Wilson ratio is determined to be 0.85 using the high-temperature effective moment. The resistivity shows a quadratic temperature dependence below 1.5 K with a {ital T}{sup 2} coefficient of 1.2 {mu}{Omega}cmK{sup {minus}2}. Unlike the other members of the series {ital R}Ni{sub 2}B{sub 2}C ({ital R}=Y, Gd{endash}Lu), YbNi{sub 2}B{sub 2}C does not order above our lowest measurement temperature of 0.34 K. The suppression of superconductivity in YbNi{sub 2}B{sub 2}C is consistent with a significantly enhanced hybridization between the conduction electrons and the 4{ital f} states. {copyright} {ital 1996 The American Physical Society.}

Functional Representation for the Born-Oppenheimer Diagonal Correction and Born-Huang Adiabatic Potential Energy Surfaces for Isotopomers of H3  

SciTech Connect

Multireference configuration interaction (MRCI) calculations of the Born-Oppenheimer diagonal correction (BODC) for H3 were performed at 1397 symmetry-unique configurations using the Born-Handy approach; isotopic substitution leads to 4041 symmetry-unique configurations for the DH2 mass combination. These results were then fit to a functional form that permits calculation of the BODC for any combination of isotopes. Mean unsigned fitting errors on a test grid of configurations not included in the fitting process were 0.14, 0.12, and 0.65 cm?1 for the H3, DH2, and MuH2 isotopomers, respectively. This representation can be combined with any Born-Oppenheimer potential energy surface (PES) to yield Born-Huang (BH) PESs; herein we choose the CCI potential energy surface, the uncertainties of which (~0.01 kcal/mol) are much smaller than the magnitude of the BODC. FORTRAN routines to evaluate these BH surfaces are provided. Variational transition state theory calculations are presented comparing thermal rate constants for reactions on the BO and BH surfaces to provide an initial estimate of the significance of the diagonal correction for the dynamics.

Spillover sites on a 19% Ni/Al sub 2 O sub 3 catalyst  

SciTech Connect

Two distinct methanation sites are clearly identified on a 19% Ni/Al{sub 2}O{sub 3} catalyst by temperature-programmed reaction (TPR) employing isotope labeling. The two sites, which are present after reduction at 975 K, are due to CO adsorption on Ni crystallites and CO and H spillover onto the Al{sub 2}O{sub 3} support. The concentration of sites on the support is 250 {mu}mol/G Al{sub 2}O{sub 3} (5 {times} 10{sup 13} molecules/cm{sup 2}), which is the same value measured for a 5.1% Ni/Al{sub 2}O{sub 3} catalyst and for a 1.0% Ru/Al{sub 2}O{sub 3} catalyst. Temperature-programmed desorption suggest that the CO and H on the Al{sub 2}O{sub 3} are in the form of a H-CO complex. The formation of this complex is an activated process, which is related to the activated adsorption of H{sub 2}. The H{sub 2} that adsorbs between 300 and 385 K is responsible for this spillover process onto the Al{sub 2}O{sub 3}. Isotope labeling and TPR were used to verify that a H-CO complex does not form on Ni/SiO{sub 2} catalysts. Carbon monoxide adsorption on Ni/SiO{sub 2} was not activated and only one methanation site was seen.

New oxyfluoride glass with high fluorine content and laser patterning of nonlinear optical BaAlBO{sub 3}F{sub 2} single crystal line  

SciTech Connect

A new oxyfluoride glass of 50BaF{sub 2}-25Al{sub 2}O{sub 3}-25B{sub 2}O{sub 3} (mol. %) with a large fraction of fluorine, i.e., F/(F + O) = 0.4, was prepared using a conventional melt-quenching method in order to synthesize new glass-ceramics containing nonlinear optical oxyfluoride crystals. The refractive index at 632.8 nm and ultra-violet cutoff wavelength of the glass were 1.564 and {approx}200 nm, respectively. Eu{sup 3+} ions in the glass showed a high quantum yield of 88% in the photoluminescence spectrum in the visible region. BaAlBO{sub 3}F{sub 2} crystals (size: 50-100 nm) showing second harmonic generations were formed through the crystallization of the glass. Lines consisting of BaAlBO{sub 3}F{sub 2} crystals were patterned successfully on the glass surface by laser irradiations (Yb:YVO{sub 4} laser with a wavelength of 1080 nm, laser power of 1.1 W, scanning speed of 8 {mu}m/s). High resolution transmission electron microscope observations combined with a focused ion beam technique indicate that BaAlBO{sub 3}F{sub 2} crystals are highly oriented just like a single crystal. The present study proposes that the new oxyfluoride glass and glass-ceramics prepared have a high potential for optical device applications.

Transport properties, specific heat and thermal conductivity of GaN nanocrystalline ceramic  

SciTech Connect

The structural and transport properties (resistivity, thermopower and Hall effect), specific heat and thermal conductivity have been measured for GaN nanocrystalline ceramic prepared by hot pressing. It was found that the temperature dependence of resistivity in temperature range 10-300 K shows the very low activation energy, which is ascribed to the shallow donor doping originating in amorphous phase of sample. The major charge carriers are electrons, what is indicated by negative sign of Hall constant and Seebeck coefficient. The thermopower attains large values (-58 {mu}V/K at 300 K) and was characterized by linear temperature dependence which suggests the diffusion as a major contribution to Seebeck effect. The high electron concentration of 1.3x10{sup 19} cm{sup -3} and high electronic specific heat coefficient determined to be 2.4 mJ/molK{sup 2} allow to conclude that GaN ceramic demonstrates the semimetallic-like behavior accompanied by very small mobility of electrons ({approx}0.1 cm{sup 2}/V s) which is responsible for its high resistivity. A low heat conductivity of GaN ceramics is associated with partial amorphous phase of GaN grains due to high pressure sintering. - Graphical Abstract: Thermal resistivity and thermopower measurements indicates the high phonon scattering and lack of phonon-drag contribution to thermopower in GaN nanoceramics pressed under 4 GPa at 800 {sup o}C.

SciTech Connect

Supersymmetry is one of the most natural extensions of the Standard Model. At low energy it may consist in the Minimal Supersymmetric Standard Model which is the framework chosen to perform the search of the stop with 350 pb{sup -1} of data collected by D0 during the RunIIa period of the TeVatron. They selected the events with an electron, a muon, missing transverse energy and non-isolated tracks, signature for the stop decay in 3-body ({bar t} {yields} bl{bar {nu}}). Since no significant excess of signal is seen, the results are interpreted in terms of limit on the stop production cross-sections, in such a way that they extend the existing exclusion region in the parameter space (m{sub {bar t}},m{sub {bar {nu}}}) up to stop masses of 168 (140) GeV for sneutrino masses of 50 (94) GeV. Finally because of the crucial role of the electromagnetic calorimeter, a fine calibration was performed using Z {yields} e{sup +}e{sup -} events, which improved significantly the energy resolution.

SciTech Connect

Epitaxial YBCO thin-film bolometers have been successfully fabricated on thin Si(100) substrates. Substrates included prethinned wafers ranging from 400 [mu]m down to 4 [mu]m thick, and a window, 0.75 [mu]m thick, micromachined into a 400-[mu]m wafer. As the Si is made thinner, the speed and responsivity both improve considerably. A 500-[mu]s rise time was achieved on the micromachined window bolometer (0.75-[mu]m-thick Si) under chopped infrared illumination. Calculations of heat flow in Si windows are in excellent agreement with the observed window-bolometer response waveform.

Biotransformation of 2,3,3,3-tetrafluoropropene (HFO-1234yf)  

SciTech Connect

2,3,3,3-Tetrafluoropropene (HFO-1234yf) is a non-ozone-depleting fluorocarbon replacement with a low global warming potential which has been developed as refrigerant. The biotransformation of HFO-1234yf was investigated after inhalation exposure. Male Sprague-Dawley rats were exposed to air containing 2000, 10,000, or 50,000 ppm HFO-1234yf for 6 h and male B6C3F1 mice were exposed to 50,000 ppm HFO-1234yf for 3.5 h in a dynamic exposure chamber (n = 5/concentration). After the end of the exposure, animals were individually housed in metabolic cages and urines were collected at 6 or 12-hour intervals for 48 h. For metabolite identification, urine samples were analyzed by {sup 1}H-coupled and decoupled {sup 19}F-NMR and by LC/MS-MS or GC/MS. Metabolites were identified by {sup 19}F-NMR chemical shifts, signal multiplicity, {sup 1}H-{sup 19}F coupling constants and by comparison with synthetic reference compounds. In all urine samples, the predominant metabolites were two diastereomers of N-acetyl-S-(3,3,3-trifluoro-2-hydroxy-propyl)-L-cysteine. In {sup 19}F-NMR, the signal intensity of these metabolites represented more than 85% (50,000 ppm) of total {sup 19}F related signals in the urine samples. Trifluoroacetic acid, 3,3,3-trifluorolactic acid, 3,3,3-trifluoro-1-hydroxyacetone, 3,3,3-trifluoroacetone and 3,3,3-trifluoro-1,2-dihydroxypropane were present as minor metabolites. Quantification of N-acetyl-S-(3,3,3-trifluoro-2-hydroxy-propyl)-L-cysteine by LC/MS-MS showed that most of this metabolite (90%) was excreted within 18 h after the end of exposure (t{sub 1/2} app. 6 h). In rats, the recovery of N-acetyl-S-(3,3,3-trifluoro-2-hydroxy-propyl)-L-cysteine excreted within 48 h in urine was determined as 0.30 {+-} 0.03, 0.63 {+-} 0.16, and 2.43 {+-} 0.86 {mu}mol at 2000, 10,000 and 50,000 ppm, respectively suggesting only a low extent (<< 1% of dose received) of biotransformation of HFO-1234yf. In mice, the recovery of this metabolite was 1.774 {+-} 0.4 {mu}mol. Metabolites identified after in vitro incubations of HFO-1234yf in liver microsomes from rat, rabbit, and human support the metabolic pathways of HFO-1234yf revealed in vivo. The obtained results suggest that HFO-1234yf is subjected to a typical biotransformation reaction for haloolefins, likely by a cytochrome P450 2E1-catalyzed formation of 2,3,3,3-tetrafluoroepoxypropane at low rates, followed by glutathione conjugation or hydrolytic ring opening.

Observation of the rare $B^0_s\\to?^+?^-$ decay from the combined analysis of CMS and LHCb data  

E-Print Network (OSTI)

A joint measurement is presented of the branching fractions $B^0_s\\to\\mu^+\\mu^-$ and $B^0\\to\\mu^+\\mu^-$ in proton-proton collisions at the LHC by the CMS and LHCb experiments. The data samples were collected in 2011 at a centre-of-mass energy of 7 TeV, and in 2012 at 8 TeV. The combined analysis produces the first observation of the $B^0_s\\to\\mu^+\\mu^-$ decay, with a statistical significance exceeding six standard deviations, and the best measurement of its branching fraction so far, and three standard deviation evidence for the $B^0\\to\\mu^+\\mu^-$ decay. The measurements are statistically compatible with SM predictions and impose stringent constraints on several theories beyond the SM.

Managing internode data communications for an uninitialized process in a parallel computer  

DOE Patents (OSTI)

A parallel computer includes nodes, each having main memory and a messaging unit (MU). Each MU includes computer memory, which in turn includes, MU message buffers. Each MU message buffer is associated with an uninitialized process on the compute node. In the parallel computer, managing internode data communications for an uninitialized process includes: receiving, by an MU of a compute node, one or more data communications messages in an MU message buffer associated with an uninitialized process on the compute node; determining, by an application agent, that the MU message buffer associated with the uninitialized process is full prior to initialization of the uninitialized process; establishing, by the application agent, a temporary message buffer for the uninitialized process in main computer memory; and moving, by the application agent, data communications messages from the MU message buffer associated with the uninitialized process to the temporary message buffer in main computer memory.

Enhanced durability of desulfurization sorbents for fluidized-bed applications  

SciTech Connect

To extend the operating temperature range and further improve the durability of fluidizable sorbents, zinc titanate, another leading regenerable sorbent, was selected for development in the later part of this project. A number of zinc titanate formulations were prepared in the 50 to 300 {mu}m range using granulation and spray drying methods. Important sorbent preparation variables investigated included zinc to titanium ratio, binder type, binder amount, and various chemical additives such as cobalt and molybdenum. A number of sorbents selected on the basis of screening tests were subjected to bench-scale testing for 10 cycles at high temperature, high pressure (HTHP) conditions using the reactor system designed and constructed during the base program. This reactor system is capable of operation either as a 2.0 in. or 3.0 in. I.D. bubbling bed and is rated up to 20 atm operation at 871{degrees}C. Bench-scale testing variables included sorbent type, temperature (550 to 750{degrees}C), gas type (KRW or Texaco gasifier gas), steam content of coal gas, and fluidizing gas velocity (6 to 15 cm/s). The sorbents prepared by spray drying showed poor performance in terms of attrition resistance and chemical reactivity. On the other hand, the granulation method proved to be very successful. For example, a highly attrition-resistant zinc titanate formulation, ZT-4, prepared by granulation exhibited virtually no zinc loss and demonstrated a constant high reactivity and sulfur capacity over 10 cycles, i.e., approximately a 60 percent capacity utilization, with Texaco gas at 750{degrees}C, 15 cm/s fluidizing velocity and 15 atm pressure. The commercial potential of the granulation method for zinc titanate manufacture was demonstrated by preparing two 80 lb batches of sorbent with zinc to titanium mol ratios of 0.8 and 1.5.

Self-powdering and nonlinear optical domain structures in ferroelastic beta'-Gd{sub 2}(MoO{sub 4}){sub 3} crystals formed in glass  

SciTech Connect

Ferroelastic beta'-Gd{sub 2}(MoO{sub 4}){sub 3}, (GMO), crystals are formed through the crystallization of 21.25Gd{sub 2}O{sub 3}-63.75MoO{sub 3}-15B{sub 2}O{sub 3} glass (mol%), and two scientific curious phenomena are observed. (1) GMO crystals formed in the crystallization break into small pieces with a triangular prism or pyramid shape having a length of 50-500 {mu}m spontaneously during the crystallizations in the inside of an electric furnace, not during the cooling in air after the crystallization. This phenomenon is called 'self-powdering phenomenon during crystallization' in this paper. (2) Each self-powdered GMO crystal grain shows a periodic domain structure with different refractive indices, and a spatially periodic second harmonic generation (SHG) depending on the domain structure is observed. It is proposed from polarized micro-Raman scattering spectra and the azimuthal dependence of second harmonic intensities that GMO crystals are oriented in each crystal grain and the orientation of (MoO{sub 4}){sup 2-} tetrahedra in GMO crystals changes periodically due to spontaneous strains in ferroelastic GMO crystals. - Graphical abstract: This figure shows the polarized optical photograph at room temperature for a particle (piece) obtained by a heat treatment of the glass at 590 deg. C for 2 h in an electric furnace in air. This particle was obtained through the self-powdering behavior in the crystallization of glass. The periodic domain structure is observed. Ferroelastic beta'-Gd{sub 2}(MoO{sub 4}){sub 3} crystals are formed in the particle, and second harmonic generations are detected, depending on the domain structure.

The evolution of a complex type B allende inclusion: An ion microprobe trace element study  

SciTech Connect

USNM 5241 is a Type B1 refractory inclusion from Allende, first described by El Goresy et al. (1985), that consists of a 1.2 mm-thick melilite-rich and spinel-poor mantle enclosing a 0.6 cm-radius spinel-rich core; the inclusion contains xenoliths of spinel-free fassaite {plus minus} melilite {plus minus} anorthite incorporated within the spinel-rich core. Detailed ion microprobe analyses of individual phases in 5241 show that the rare earth element (REE) concentrations in mantle melilite vary irregularly with increasing distance from the rim of the inclusion, at first decreasing immediately below the rim and then remaining constant between {approximately}0.4 and 1.0 mm. More than 1.0 mm from the rim, the REE concentrations again decrease. Although counterintuitive in the context of traditional fractional crystallization models, these REE variations are in fact broadly consistent with such a model in light of recent experimental measurements of D{sub REE3+ (mel)}, that show a strong inverse correlation of D with the akermanite content of the melilite. Local variations, over distances of <20 {mu}m, in the akermanite content of mantle melilite--as much as 5-10 mol% Ak--with accompanying fluctuations in REE contents, are due to reaction of gehlenitic melilite with tiny inclusions of fassaite, producing narrow zones of more akermanitic melilite surrounding more fassaitic pyroxene. The authors interpret 5241 as having formed largely by fractional crystallization during the first {approximately}40% of its solidification; this was followed by fractional crystallization + xenolith assimilation during the last 60%.

We consider the upward-going muon flux due to the WIMP annihilations in the cores of the sun and the earth, including the upper bound on the branching ratio for $B_s \\to \\mu^+ \\mu^-$ decay. We find that the constraint from $B_s \\to \\mu^+ \\mu^-$ is very strong in most parameter space, and exclude the supergravity parameter space regions where the expected upward-going muon fluxes are within the expected reach of AMANDA II.

Measurement of the Formation Rate of Muonic Hydrogen Molecules  

E-Print Network (OSTI)

Background: The rate \\lambda_pp\\mu\\ characterizes the formation of pp\\mu\\ molecules in collisions of muonic p\\mu\\ atoms with hydrogen. In measurements of the basic weak muon capture reaction on the proton to determine the pseudoscalar coupling g_P, capture occurs from both atomic and molecular states. Thus knowledge of \\lambda_pp\\mu\\ is required for a correct interpretation of these experiments. Purpose: Recently the MuCap experiment has measured the capture rate \\Lambda_S from the singlet p\\mu\\ atom, employing a low density active target to suppress pp\\mu\\ formation (PRL 110, 12504 (2013)). Nevertheless, given the unprecedented precision of this experiment, the existing experimental knowledge in \\lambda_pp\\mu\\ had to be improved. Method: The MuCap experiment derived the weak capture rate from the muon disappearance rate in ultra-pure hydrogen. By doping the hydrogen with 20 ppm of argon, a competing process to pp\\mu\\ formation was introduced, which allowed the extraction of \\lambda_pp\\mu\\ from the observed t...

Law of Conservation of Muons  

DOE R&D Accomplishments (OSTI)

A multiplicative selection rule for mu meson-electron transitions is proposed. A "muon parity" = -1 is considered for the muon and its neutrino, while the "muon parity" for all other particles is +1. The selection rule then states that (-1) exp(no. of initial (-1) parity particles) = (-1) exp(no. of final (-1) parity particles). Several reactions that are forbidden by an additive law but allowed by the multiplicative law are suggested; these reactions include mu{sup +} .> e{sup +} + nu{sub mu} + {ovr nu}{sub e}, e{sup -} + e{sup -} .> mu{sup -} + mu{sup -}, and muonium .> antimuonium (mu{sup +} + e{sup -} .> mu{sup -} + e{sup +}). An intermediate-boson hypothesis is suggested. (T.F.H.)

Lepton-Flavor Violation in the Left-handed Slepton Production at Future Lepton Colliders  

E-Print Network (OSTI)

The Super-Kamiokande atmospheric neutrino data suggest existence of the large lepton-flavor violating (LFV) interaction in the higher energy scale. If the minimal supersymmetric standard model is extended to have right-handed neutrinos, the left-handed sleptons in the second and third generations are expected to have the LFV masses in the minimal supergravity scenario. In this article we study the LFV signals in the left-handed slepton production at $\\mu^+\\mu^-$ colliders and $\\e^+\\e^-$ linear colliders (LC's), $\\mu^+\\mu^-(\\e^+\\e^-)\\to\\tau\\mu +4jets + \\E$ and $\\mu^+\\mu^-(\\e^+\\e^-)\\to\\tau\\mu l+ 2jets+ \\E$. The main background comes from decay of a tau lepton into a muon in the lepton-flavor conserving slepton pair production. They are significantly reduced by the energy and the impact parameter cuts for the muon. At $\\mu^+\\mu^-$ colliders (LC's) it may be possible to reach the mixing angle $\\sin 2\\theta_{\\tilde{\

Pigments which reflect infrared radiation from fire  

DOE Patents (OSTI)

Conventional paints transmit or absorb most of the intense infrared (IR) radiation emitted by fire, causing them to contribute to the spread of fire. The present invention comprises a fire retardant paint additive that reflects the thermal IR radiation emitted by fire in the 1 to 20 micrometer (.mu.m) wavelength range. The important spectral ranges for fire control are typically about 1 to about 8 .mu.m or, for cool smoky fires, about 2 .mu.m to about 16 .mu.m. The improved inventive coatings reflect adverse electromagnetic energy and slow the spread of fire. Specific IR reflective pigments include titanium dioxide (rutile) and red iron oxide pigments with diameters of about 1 .mu.m to about 2 .mu.m and thin leafing aluminum flake pigments.

Enhanced Sensitivities for the Searches of Neutrino Magnetic Moments through Atomic Ionization  

SciTech Connect

A new detection channel on atomic ionization for possible neutrino electromagnetic interactions is identified and studied. Significant sensitivity enhancement is demonstrated when the energy transfer to the target is of the atomic-transition scale. The interaction cross section induced by neutrino magnetic moments ({mu}{sub {nu}}) is evaluated with the equivalent photon method. A new limit of {mu}{sub {nu}}({nu}e)<1.3x10{sup -11}{mu}{sub B} at 90% confidence level is derived by using current reactor neutrino data. Potential reaches for future experiments are explored. Experiments with sub-keV sensitivities can probe {mu}{sub {nu}} to 10{sup -13}{mu}{sub B}. Positive observations of {mu}{sub {nu}} in this range would imply that neutrinos are Majorana particles.

Method for fabrication of crack-free ceramic dielectric films  

DOE Patents (OSTI)

The invention provides a process for forming crack-free dielectric films on a substrate. The process comprise the application of a dielectric precursor layer of a thickness from about 0.3 .mu.m to about 1.0 .mu.m to a substrate. The deposition is followed by low temperature heat pretreatment, prepyrolysis, pyrolysis and crystallization step for each layer. The deposition, heat pretreatment, prepyrolysis, pyrolysis and crystallization are repeated until the dielectric film forms an overall thickness of from about 1.5 .mu.m to about 20.0 .mu.m and providing a final crystallization treatment to form a thick dielectric film. Also provided was a thick crack-free dielectric film on a substrate, the dielectric forming a dense thick crack-free dielectric having an overall dielectric thickness of from about 1.5 .mu.m to about 20.0 .mu.m.

Charge Sharing Effect on 600 ?m Pitch Pixelated CZT Detector for Imaging Applications  

E-Print Network (OSTI)

We are currently investigating the spatial resolution of highly pixelated Cadmium Zinc Telluride (CZT) detector for imaging applications. A 20 mm {\\times} 20 mm {\\times} 5 mm CZT substrate was fabricated with 600 {\\mu}m pitch pixels (500 {\\mu}m anode pixels with 100 {\\mu}m gap) and coplanar cathode. Charge sharing between two pixels was studied using collimated 122 keV gamma ray source. Experiments show a resolution of 125 {\\mu}m FWHM for double-pixel charge sharing events when the 600 {\\mu}m pixelated and 5 mm thick CZT detector biased at -1000 V. In addition, we analyzed the energy response of the 600 {\\mu}m pitch pixelated CZT detector.

Preliminary exposure assessment for Kuwaiti consumers to polycyclic aromatic hydrocarbons in seafood  

SciTech Connect

Levels of PAHs in seafood from Kuwaiti market were determined. Results showed that most of the samples contained significant amounts of total PAHs. Naphthalene constituted the highest PAH burden of the samples. Nuwaibi had the highest level of total PAHs (472.6 {mu}g/kg, dry wt). Others ranged from 0.86 to 55.96 {mu}g/kg dry wt. The results of exposure assessment for the average consumer indicated a daily intake of 0.231 {mu}g of total PAH from seafood. BaP equivalent intake was calculated to be 0.0167 {mu}g/d. For the above average consumer, total PAH intake was 0.326 {mu}g/d; and BaP equivalents were 0.025 {mu}g/d. These daily intake levels were quite comparable with those reported for the average American consumer. 18 refs., 3 figs., 8 tabs.

Precise Measurement of the Positive Muon Anomalous Magnetic Moment  

E-Print Network (OSTI)

A precise measurement of the anomalous g value, a_mu=(g-2)/2, for the positive muon has been made at the Brookhaven Alternating Gradient Synchrotron. The result a_mu^+=11 659 202(14)(6) X 10^{-10} (1.3 ppm) is in good agreement with previous measurements and has an error one third that of the combined previous data. The current theoretical value from the standard model is a_mu(SM)=11 659 159.6(6.7) X 10^{-10} (0.57 ppm) and a_mu(exp)-a_mu(SM)=43(16) X 10^{-10} in which a_mu(exp) is the world average experimental value. This difference may be due to physics beyond the standard model.

The $?$-deformed Segal-Bargmann transform is a Hall type transform  

E-Print Network (OSTI)

We present an explanation of how the $\\mu$-deformed Segal-Bargmann spaces, that are studied in various articles of the author in collaboration with Angulo, Echevarria and Pita, can be viewed as deserving their name, that is, how they should be considered as a part of Segal-Bargmann analysis. This explanation relates the $\\mu$-deformed Segal-Bargmann transforms to the generalized Segal-Bargmann transforms introduced by B. Hall using heat kernel analysis. All the versions of the $\\mu$-deformed Segal-Bargmann transform can be understood as Hall type transforms. In particular, we define a $\\mu$-deformation of Hall's "Version C" generalized Segal-Bargmann transform which is then shown to be a $\\mu$-deformed convolution with a $\\mu$-deformed heat kernel followed by analytic continuation. Our results are generalizations and analogues of the results of Hall.

Origin of periodic domain structure in Er{sup 3+}-doped beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystal lines patterned by laser irradiations in glasses  

SciTech Connect

Er{sup 3+}-doped beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystal lines are patterned on the surface of Er{sub 2}O{sub 3}-Gd{sub 2}O{sub 3}-Sm{sub 2}O{sub 3}-MoO{sub 3}-B{sub 2}O{sub 3} glasses by continuous-wave Yb:YVO{sub 4} laser irradiations (wavelength: 1080 nm, power: 1.3 W, scanning speeds: 5 {mu}m/s), and the origin of the periodicity of self-organized domain structures with high and low refractive index regions in crystal lines is examined from polarized optical microscope (POM) observations, micro-Raman scattering spectrum, and photoluminescence spectrum measurements. It is found that the periodicity of domain structures changes largely depending on Er{sub 2}O{sub 3} content, i.e., the length of high (bright color in POM observations) and low (dark color) refractive index regions increases with increasing Er{sub 2}O{sub 3} content and homogeneous crystal lines with no periodic domain structures are patterned in Er{sub 2}O{sub 3}-Sm{sub 2}O{sub 3}-MoO{sub 3}-B{sub 2}O{sub 3} glass with no Gd{sub 2}O{sub 3}. Considering that the degree of ferroelasticities in beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystals decreases due to the incorporation of Er{sup 3+} ions, it is demonstrated that the origin of periodic domain structures in laser-patterned lines is due to spontaneous strains in ferroelastic beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystals. - Graphical abstract: This figure shows the polarized optical photographs (top view) for the lines patterned by laser irradiations with the power of P=1.3 W and the scanning speed of S=5 {mu}m/s in xEr{sub 2}O{sub 3}-(18.25-x)Gd{sub 2}O{sub 3}-3Sm{sub 2}O{sub 3}-63.75MoO{sub 3}-15B{sub 2}O{sub 3} (mol%) glasses. This figure indicates that the periodicity of domain structures in beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystal lines, i.e., the lengths of bright (high refractive index) and dark (low refractive index) color regions, changes depending on the amount of Er{sub 2}O{sub 3} addition. It is demonstrated that the origin of the periodicity of domain structures is due to spontaneous strains in ferroelastic beta'-(Sm,Gd){sub 2}(MoO{sub 4}){sub 3} crystals.

We investigate the effects of baryon chemical potential \\mu on the shear viscosity coefficient \\eta and the viscosity to entropy density ratio \\eta/s of a pion-nucleon gas mixture. We find that \\eta is an increasing function of T and \\mu, while the ratio \\eta/s turns to a decreasing function in a wide region of T-\\mu plane. In the kinematical region we studied, the smallest value of \\eta/s is about 0.3.

On the basis of perturbation theory in fine structure constant alpha and the ratio of electron to muon masses we calculate one-loop vacuum polarization, electron vertex corrections, nuclear structure and recoil corrections to hyperfine splitting of the ground state in muonic lithium ions $(\\mu\\ e\\ ^6_3Li)^+$ and $(\\mu\\ e\\ ^7_3Li)^+$. We obtain total results for the ground state small hyperfine splittings in $(\\mu\\ e\\ ^6_3Li)^+$ $\\Delta\

Comparison of two immunoradiometric assays for serum thyrotropin  

SciTech Connect

An ultra-sensitive TSH assay capable of detecting subnormal TSH levels would be useful in confirming suppressed pituitary function as seen in hyperthyroidism. Two sensitive immunoradiometric TSH assays (IRMA's) were studied to determine how well they distinguished thyrotoxic patients from normal subjects. Serono Diagnostics' method employs three monoclonal antibodies specific for different regions of the TSH molecule with a minimum detectable dose (MDD) limit of 0.1 ..mu..IU/ml. Precision studies using a low TSH control in the 1.8 ..mu..IU/ml range gave CV's of 15.0%. Boots-Celltech Diagnostics method is a two site IRMA using two monoclonal antibodies. The MDD limit is 0.05 ..mu..IU/ml with precision CV's of 29.3% at a TSH control range of 0.62 ..mu..IU/ml. In 24 chemically thyrotoxic patients, the mean serum TSH concentration was significantly lower than in the normal control subjects: for Serono, 0.19 ..mu..IU/ml vs. 2.34 ..mu..IU/ml and for Boots Celltech, 0.18 IU/ml vs 2.06 ..mu..IU/ml. The range of TSH was 0 to 0.5 ..mu..IU/ml in thyrotoxic patients using Serono with the exception of one patient having a TSH value of 0.8 ..mu..IU/ml. The normal range was 0.6 to 6.0 ..mu..IU/ml. For Boots Celltech the thyrotoxic range was 0 to 0.2 ..mu..IU/ml with that same thyrotoxic patient giving a TSH value of 0.7 ..mu..IU/ml with a normal range of 0.6 to 5.0 IU/ml. Serum TSH measurements using both procedures are highly sensitive for distinguishing thyrotoxic patients from normal subjects and are useful to confirm suppressed pituitary function.

Enzymatic synthesis of dimaltosyl-{beta}-cyclodextrin via a transglycosylation reaction using TreX, a Sulfolobus solfataricus P2 debranching enzyme  

SciTech Connect

Di-O-{alpha}-maltosyl-{beta}-cyclodextrin ((G2){sub 2}-{beta}-CD) was synthesized from 6-O-{alpha}-maltosyl-{beta}-cyclodextrin (G2-{beta}-CD) via a transglycosylation reaction catalyzed by TreX, a debranching enzyme from Sulfolobus solfataricus P2. TreX showed no activity toward glucosyl-{beta}-CD, but a transfer product (1) was detected when the enzyme was incubated with maltosyl-{beta}-CD, indicating specificity for a branched glucosyl chain bigger than DP2. Analysis of the structure of the transfer product (1) using MALDI-TOF/MS and isoamylase or glucoamylase treatment revealed it to be dimaltosyl-{beta}-CD, suggesting that TreX transferred the maltosyl residue of a G2-{beta}-CD to another molecule of G2-{beta}-CD by forming an {alpha}-1,6-glucosidic linkage. When [{sup 14}C]-maltose and maltosyl-{beta}-CD were reacted with the enzyme, the radiogram showed no labeled dimaltosyl-{beta}-CD; no condensation product between the two substrates was detected, indicating that the synthesis of dimaltosyl-{beta}-CD occurred exclusively via transglycosylation of an {alpha}-1,6-glucosidic linkage. Based on the HPLC elution profile, the transfer product (1) was identified to be isomers of 6{sup 1},6{sup 3}- and 6{sup 1},6{sup 4}-dimaltosyl-{beta}-CD. Inhibition studies with {beta}-CD on the transglycosylation activity revealed that {beta}-CD was a mixed-type inhibitor, with a K{sub i} value of 55.6 {mu}mol/mL. Thus, dimaltosyl-{beta}-CD can be more efficiently synthesized by a transglycosylation reaction with TreX in the absence of {beta}-CD. Our findings suggest that the high yield of (G2){sub 2}-{beta}-CD from G2-{beta}-CD was based on both the transglycosylation action mode and elimination of the inhibitory effect of {beta}-CD.

Search for Neutral Heavy Leptons in the NuTeV Experiment at Fermilab  

E-Print Network (OSTI)

Preliminary results from a search for neutral heavy leptons in the NuTeV experiment at Fermilab. The upgraded NuTeV neutrino detector for the 1996-1997 run included an instrumented decay region for the NHL search which, combined with the NuTeV calorimeter, allows detection in several decay modes (mu-mu-nu, mu-e-nu, mu-pi, e-pi, and e-e-nu). We see no evidence for neutral heavy leptons in our current search in the mass range from 0.3 GeV to 2.0 GeV decaying into final states containing a muon.

Determining the Flavour Content of the Low-Energy Solar Neutrino Flux  

E-Print Network (OSTI)

We study the sensitivity of the HELLAZ and Borexino solar neutrino experiments on discriminating the neutrino species nu_e, anti-nu_e, nu_{mu,tau}, anti-nu_{mu,tau}, and nu_{sterile} using the difference in the recoil electron kinetic energy spectra in elastic neutrino-electron scattering. We find that one can observe a non-vanishing nu_{mu,tau} component in the solar neutrino flux, especially when the nu_e survival probability is low. Also, if the data turn out to be consistent with nu_e nu_{mu,tau} oscillations, an anti-nu_e component can be excluded effectively.
