Comment on “New Brans-Dicke wormholes”  

Science Journals Connector (OSTI)

It is shown that the recently claimed two new Brans-Dicke wormhole solutions [F. He and S-W. Kim, Phys. Rev. D 65, 084022 (2002)] are not really new solutions. They are just the well known Brans-Dicke solutions of Class I and II in a different conformal gauge.

Brans-Dicke cylindrical wormholes  

SciTech Connect

Static axisymmetric thin-shell wormholes are constructed within the framework of the Brans-Dicke scalar-tensor theory of gravity. Examples of wormholes associated with vacuum and electromagnetic fields are studied. All constructions must be threaded by exotic matter, except in the case of geometries with a singularity of finite radius, associated with an electric field, which can have a throat supported by ordinary matter. These results are achieved with any of the two definitions of the flare-out condition considered.

Cosmic acceleration and Brans-Dicke theory  

SciTech Connect

We study the accelerated expansion of the universe by exploring the Brans-Dicke parameter in different eras. For this, we take the FRW universe model with a viscous fluid (without potential) and the Bianchi type-I universe model with a barotropic fluid (with and without a potential). We evaluate the deceleration parameter and the Brans-Dicke parameter to explore cosmic acceleration. It is concluded that accelerated expansion of the universe can also be achieved for higher values of the Brans-Dicke parameter in some cases.

False vacuum decay in Jordan-Brans-Dicke cosmologies  

SciTech Connect

We examine the bubble nucleation rate in a first-order phase transition taking place in a background Jordan-Brans-Dicke cosmology. We compute the leading order terms in the nucleation rate when the Jordan-Brans-Dicke field is large (i.e., late times) by means of a Weyl rescaling of the fields in the theory. We find that despite the fact that the Jordan-Brans-Dicke field (hence the effective gravitational constant) has a time dependence in the false vacuum, at late times the nucleation rate is time independent. 21 refs.

Electrical conductivity in granular media and Branly’s coherer: A simple experiment  

Science Journals Connector (OSTI)

We show how a simple laboratory experiment can illustrate certain electrical transport properties of metallic granular media. At a low critical external voltage a transition from an insulating to a conductive state is observed. This transition comes from an electro-thermal coupling in the vicinity of the microcontacts between grains where microwelding occurs. Our apparatus allows us to obtain an implicit determination of the microcontact temperature which is analogous to the use of a resistive thermometer. The experiment also helps us explain an old problem Branly’s coherer effect which was used as a radio wavedetector for the first wireless radio transmission and is based on the sensitivity of the conductivity of metal filings to an electromagnetic wave.

Autoparallel orbits in Kerr Brans-Dicke spacetimes  

E-Print Network (OSTI)

The bounded orbital motion of a massive spinless test particle in the background of a Kerr Brans-Dicke geometry is analysed in terms of worldlines that are auto-parallels of different metric compatible spacetime connections. In one case the connection is that of Levi-Civita with zero-torsion. In the second case the connection has torsion determined by the gradient of the Brans-Dicke background scalar field. The calculations permit in principle to discriminate between these possibilities.

Lunar Laser Ranging and the Brans-Dicke Theory  

Science Journals Connector (OSTI)

Laser ranging to an optical corner reflector on the lunar surface may make possible a test of non-Newtonian gravitational theories. The results of a theoretical calculation of the Brans-Dicke corrections to the laser-pulse transit time are compared with results previously obtained for the Einstein theory. A further analysis of the measurable non-Newtonian correction term which dominates the predictions of both theories indicates that the term probably is common to all Lorentz-covariant gravitational theories.

The cosmic coincidence in Brans-Dicke cosmologies  

E-Print Network (OSTI)

Among the suggested solutions to the cosmological constant problem, we find the idea of a dynamic vacuum, with an energy density decaying with the universe expansion. We investigate the possibility of a variation in the gravitational constant as well, induced, at the cosmological scale, by the vacuum decay. We consider an effective Brans-Dicke theory in the spatially flat FLRW spacetime, finding late time solutions characterized by a constant ratio between the matter and vacuum energy densities. By using the observed limits for the universe age, we fix the only free parameter of our solutions, obtaining a relative matter density in the range 0.25-0.4. In particular, for Ht = 1 we obtain a relative matter density equals to 1/3. This constitutes a possible explanation for another problem related to the cosmological term, the cosmic coincidence problem.

Cosmic Microwave Background Temperature and Polarization Anisotropy in Brans-Dicke Cosmology  

E-Print Network (OSTI)

We develop a formalism for calculating cosmic microwave background (CMB) temperature and polarization anisotropies in cosmological models with Brans-Dicke gravity. We then modify publicly available Boltzmann codes to calculate numerically the temperature and polarization power spectra. Results are illustrated with a few representative models. Comparing with the general-relativistic model with the same cosmological parameters, both the amplitude and the width of the acoustic peaks are different in the Brans-Dicke models. We use a covariance-matrix calculation to investigate whether the effects of Brans-Dicke gravity are degenerate with those of variation in other cosmological parameters and to simultaneously determine whether forthcoming CMB maps might be able to distinguish Brans-Dicke and general-relativistic cosmology. Although the predicted power spectra for plausible Brans-Dicke models differ from those in general relativity only slightly, we find that MAP and/or the Planck Surveyor may in principle provide a test of Brans-Dicke theory that is competitive to solar-system tests. For example, if all other parameters except for the CMB normalization are fixed, a value of the Brans-Dicke parameter omega as large as 500 could be identified with MAP, and for Planck, values as large as omega \\simeq3000 could be identified; these sensitivities are decreased roughly by a factor of 3 if we marginalize over the baryon density, Hubble constant, spectral index, and reionization optical depth. In more general scalar-tensor theories, omega may evolve with time, and in this case, the CMB probe would be complementary to that from solar-system tests.

Modified Brans-Dicke theory with space-time anisotropic parameters  

E-Print Network (OSTI)

We consider the ADM formalism of the Brans-Dicke theory and propose an anisotropic extension of the theory by introducing five free parameters. We find that the resulting theory reveals many interesting aspects which are not present in the original BD theory. We first discuss the ghost instability and strong coupling problems which are present in the gravity theory without the full diffeomorphism symmetry and show that they can be avoided in a region of the parameter space. We also perform the post-Newtonian approximation and show that the constraint of the Brans-Dicke parameter $\\omega_{{\\rm BD}}$ being large to be consistent with the solar system observations could be evaded in the extended theory. We also discuss that accelerating Universe can be achieved without the need of the potential for the Brans-Dicke scalar.

Exact solutions of Brans-Dicke cosmology with decaying vacuum density  

E-Print Network (OSTI)

We investigate cosmological solutions of Brans-Dicke theory with both the vacuum energy density and the gravitational constant decaying linearly with the Hubble parameter. A particular class of them, with constant deceleration factor, sheds light on the cosmological constant problems, leading to a presently small vacuum term, and to a constant ratio between the vacuum and matter energy densities. By fixing the only free parameter of these solutions, we obtain cosmological parameters in accordance with observations of both the relative matter density and the universe age. In addition, we have three other solutions, with Brans-Dicke parameter w = -1 and negative cosmological term, two of them with a future singularity of big-rip type. Although interesting from the theoretical point of view, two of them are not in agreement with the observed universe. The third one leads, in the limit of large times, to a constant relative matter density, being also a possible solution to the cosmic coincidence problem.

Constraining Red-shift Parametrization Parameters in Brans-Dicke Theory: Evolution of Open Confidence Contours  

E-Print Network (OSTI)

In Brans Dicke theory of gravity, from the nature of the scalar field-potential considered, the dark energy, dark matter, radiation densities predicted by different observations and the closedness of the universe considered, we can fix our $\\omega_{BD}$, the Brans Dicke parameter, keeping only the thing in mind that from different solar system constrains it must be greater than $5\\times 10^{5}$. Once we have a value, satisfying the required lower boundary, in our hand we proceed for setting unknown parameters of the different dark energy models' EoS parameter. In this paper we work with three well known red shift parametrizations of dark energy EoS. To constrain their free parameters for Brans Dicke theory of gravity we take twelve point red shift vs Hubble's parameter data and perform $\\chi^{2}$ test. We present the observational data analysis mechanism for Stern, Stern+BAO and Stern+BAO+CMB observations. Minimising $\\chi^2$, we obtain the best fit values and draw different confidence contours. We analyze the contours physically. Also we examine the best fit of distance modulus for our theoretical models and the Supernovae Type Ia Union2 sample. For Brans Dicke theory of gravity the difference from the mainstream confidence contouring method of data analysis id that the confidence contours evolved are not at all closed contours like a circle or a ellipse.

Propagation of quantum particles in Brans-Dicke spacetime. The case of Gamma Ray Bursts  

E-Print Network (OSTI)

The propagation of boson particles in a gravitational field described by the Brans-Dicke theory of gravity is analyzed. We derive the wave function of the scalar particles, and the effective potential experienced by the quantum particles considering the role of the varying gravitational coupling. Besides, we calculate the probability to find the scalar particles near the region where a naked singularity is present. The extremely high energy radiated in such a situation could account for the huge emitted power observed in Gamma Ray Bursts.

Thermodynamics of charged rotating black branes in Brans-Dicke theory with quadratic scalar field potential  

SciTech Connect

We construct a class of charged rotating solutions in (n+1)-dimensional Maxwell-Brans-Dicke theory with flat horizon in the presence of a quadratic potential and investigate their properties. These solutions are neither asymptotically flat nor (anti)-de Sitter. We find that these solutions can present black brane, with inner and outer event horizons, an extreme black brane or a naked singularity provided the parameters of the solutions are chosen suitably. We compute the finite Euclidean action through the use of counterterm method, and obtain the conserved and thermodynamic quantities by using the relation between the action and free energy in grand-canonical ensemble. We find that these quantities satisfy the first law of thermodynamics, and the entropy does not follow the area law.

Secondary kinetics of methanol decomposition : theoretical rate coefficients for {sup 3}CH{sub 2} + OH, {sup 3}CH{sub 2} + {sup 3}CH{sub 2}, and {sup 3}CH{sub 2} + CH{sub 3}.  

SciTech Connect

Direct variable reaction coordinate transition state theory (VRC-TST) rate coefficients are reported for the {sup 3}CH{sub 2} + OH, {sup 3}CH{sub 2} + {sup 3}CH{sub 2}, and {sup 3}CH{sub 2} + CH{sub 3} barrierless association reactions. The predicted rate coefficient for the {sup 3}CH{sub 2} + OH reaction ({approx} 1.2 x 10{sup -10} cm{sup 3} molecule{sup -1} s{sup -1} for 300-2500 K) is 4-5 times larger than previous estimates, indicating that this reaction may be an important sink for OH in many combustion systems. The predicted rate coefficients for the {sup 3}CH{sub 2} + CH{sub 3} and {sup 3}CH{sub 2} + {sup 3}CH{sub 2} reactions are found to be in good agreement with the range of available experimental measurements. Product branching in the self-reaction of methylene is discussed, and the C{sub 2}H{sub 2} + 2H and C{sub 2}H{sub 2} + H{sub 2} products are predicted in a ratio of 4:1. The effect of the present set of rate coefficients on modeling the secondary kinetics of methanol decomposition is briefly considered. Finally, the present set of rate coefficients, along with previous VRC-TST determinations of the rate coefficients for the self-reactions of CH{sub 3} and OH and for the CH{sub 3} + OH reaction, are used to test the geometric mean rule for the CH{sub 3}, {sup 3}CH{sub 2}, and OH fragments. The geometric mean rule is found to predict the cross-combination rate coefficients for the {sup 3}CH{sub 2} + OH and {sup 3}CH{sub 2} + CH{sub 3} reactions to better than 20%, with a larger (up to 50%) error for the CH{sub 3} + OH reaction.

Reversible and irreversible spacetime thermodynamics for general Brans-Dicke theories  

SciTech Connect

We derive the equations of motion for Palatini F(R) gravity by applying an entropy balance law TdS={delta}Q+{delta}N to the local Rindler wedge that can be constructed at each point of spacetime. Unlike previous results for metric F(R), there is no bulk viscosity term in the irreversible flux {delta}N. Both theories are equivalent to particular cases of Brans-Dicke scalar-tensor gravity. We show that the thermodynamical approach can be used ab initio also for this class of gravitational theories and it is able to provide both the metric and scalar equations of motion. In this case, the presence of an additional scalar degree of freedom and the requirement for it to be dynamical naturally imply a separate contribution from the scalar field to the heat flux {delta}Q. Therefore, the gravitational flux previously associated to a bulk viscosity term in metric F(R) turns out to be actually part of the reversible thermodynamics. Hence we conjecture that only the shear viscosity associated with Hartle-Hawking dissipation should be associated with irreversible thermodynamics.

Biodiesel derived from vegetable oils and animal fats can be used in diesel engines with little or no modifications. In this work, the combustion, performance and emission characteristics of various biodiesel (rice bran oil and pungam oil) and their blends are evaluated in a direct injection diesel engine. Lower ignition delay, higher peak pressure and heat release rate with almost same brake thermal efficiency are obtained for 20% biodiesel blend as compared with diesel fuel. They exhibited lower unburned hydrocarbon, carbon monoxide and soot emissions with a penalty of higher NOx emissions.

Investigation on combustion characteristics of crude rice bran oil methyl ester blend as a heavy duty automotive engine fuel  

Science Journals Connector (OSTI)

In the present work, an attempt was made to test the suitability of crude rice bran oil methyl ester (CRBME) blend as a heavy duty automotive engine fuel. A four stroke, six cylinder direct injection 117.6 kW turbo-charged compression ignition (CI) engine was used for the work. The operation of the engine with CRBME blend showed that the peak pressure increased with lower maximum rate of pressure rise and maximum heat release rate with shorter delay period. Burning rate of the CRBME blend was slower and required a higher crank angle to complete the combustion cycle when compared to diesel. The brake thermal efficiency of the CRBME blend was lower than that of diesel at all speeds except at 2300rpm. As the measured combustion and performance parameters for CRBME blend differs only by a smaller magnitude when compared with diesel, this investigation ensures the suitability of the CRBME blend as fuel for heavy duty automotive engine without any design modifications [Received: August 12, 2010; Accepted: August 29, 2010

Seasonal variation of CH4 emissions from central California Seasonal variation of CH4 emissions from central California Title Seasonal variation of CH4 emissions from central California Publication Type Journal Article Year of Publication 2012 Authors Jeong, Seongeun, Chuanfeng Zhao, Arlyn E. Andrews, Laura Bianco, James M. Wilczak, and Marc L. Fischer Journal Journal of Geophysical Research - Atmospheres Volume 117 Issue D11 Keywords atmospheric transport, emission inventory, greenhouse gas, inverse model, methane Abstract We estimate seasonal variations in methane (CH4) emissions from central California from December 2007 through November 2008 by comparing CH4 mixing ratios measured at a tall tower with transport model predictions based on a global 1° a priori CH4emissions map (EDGAR32) and a 10 km seasonally varying California-specific map, calibrated to statewide by CH4emission totals. Atmospheric particle trajectories and surface footprints are computed using the Weather Research and Forecasting and Stochastic Time-Inverted Lagrangian Transport models. Uncertainties due to wind velocity and boundary layer mixing depth are evaluated using measurements from radar wind profilers. CH4signals calculated using the EDGAR32 emission model are larger than those based on the California-specific model and in better agreement with measurements. However, Bayesian inverse analyses using the California-specific and EDGAR32 maps yield comparable annually averaged posterior CH4emissions totaling 1.55 ± 0.24 times and 1.84 ± 0.27 times larger than the California-specific prior emissions, respectively, for a region of central California within approximately 150 km of the tower. If these results are applicable across California, state total CH4 emissions would account for approximately 9% of state total greenhouse gas emissions. Spatial resolution of emissions within the region near the tower reveal seasonality expected from several biogenic sources, but correlations in the posterior errors on emissions from both prior models indicate that the tower footprints do not resolve spatial structure of emissions. This suggests that including additional towers in a measurement network will improve the regional specificity of the posterior estimates.

SciTech Connect

A pulse radiolysis technique was used to measure the UV absorption spectra of (CH{sub 3}O){sub 2}CHOCH{sub 2}({center_dot}) [A] and (CH{sub 3}O){sub 2}CHOCH{sub 2}O{sub 2}({center_dot}) [B] radicals derived from trimethoxymethane over the range 220--320 nm. The self-reaction rate constants for these radicals were k{sub 5} = (3.5 {+-} 0.5) {times} 10{sup {minus}11} and k{sub 6 obs} = (1.3 {+-} 0.2) {times} 10{sup {minus}11} cm{sup 3}/molecule s. Rate constants for reactions of B radicals with NO and NO{sub 2} were k{sub 7} = (9.0 {+-} 1.2) {times} 10{sup {minus}12} and k{sub 8} = (1.0 {+-} 0.2) {times} 10{sup {minus}11} cm{sup 3}/molecule s, respectively. Rate constants for the reaction of OH radicals and F atoms with trimethoxymethane and the reaction of A radicals with O{sub 2} were k{sub 1} = (6.0 {+-} 0.5) {times} 10{sup {minus}12}, k{sub 3} = (3.0 {+-} 0.7) {times} 10{sup {minus}10}, and k{sub 2} = (9.2 {+-} 1.5) {times} 10{sup {minus}12} cm{sup 3}/molecule s, respectively. Relative rate techniques were used to measure k(Cl + trimethoxymethane) = (1.5 {+-} 0.2) {times} 10{sup {minus}10} cm{sup 3}/molecule s. OH-radical-initiated oxidation of trimethoxymethane in air gives dimethyl carbonate in a molar yield of 81 {+-} 10%. These results are discussed with respect to the atmospheric chemistry of automotive fuel additives.

Influence of propane on CO2/CH4 and N2/CH4 separations in CHA zeolite membranes  

Science Journals Connector (OSTI)

Abstract Two types of CHA zeolite membranes (SAPO-34, SSZ-13) were used for CO2/CH4, N2/CH4, and CO2/i-butane separations at both low (270 and 350 kPa) and high (1.73 MPa) pressures. The SSZ-13 membranes were more selective, with CO2/CH4 separation selectivities as high as 280 and N2/CH4 separation selectivities of 12 at 270 kPa feed pressure. For both types of membranes, selectivities and permeances decreased as the feed pressure increased. The CO2/i-butane separation selectivities were greater than 500,000 for SAPO-34 membranes, indicating extremely low densities of defects because i-butane is too large to enter the CHA pores. The CO2/i-butane selectivities were smaller for SSZ-13 membranes (2,800–20,000), in part because the SSZ-13 layer was on the outside of the porous mullite tubes and sealing the membrane on the zeolite surface was more difficult than for the SAPO-34 membranes that were grown on the inside of glazed alumina tubes. Propane, in feed concentrations from 1 to 9%, significantly influenced separations by decreasing permeances in most cases. The effect was larger for N2/CH4 than for CO2/CH4 mixtures, apparently because the more strongly-adsorbing CO2 competes better than N2 with propane for adsorption sites. Although propane caused permeances to decrease significantly over time, selectivities decreased much less. Propane decreased permeances more for SAPO-34 membranes than for SSZ-13 membranes at 350 kPa, and at high pressure propane even increased CO2 permeances and decreased CH4 permeances in SSZ-13 membranes, thus significantly increasing CO2/CH4 selectivities. Propane permeances reached steady state relatively quickly because its permeation was mostly through defects, but CO2, N2, and CH4 permeances did not stabilize in the presence of propane, even after seven days. The effects of propane were reversible when it was removed from the feed and the membranes were heated.

A comparative evaluation of Al 2 O 3 coated low heat rejection diesel engine performance and emission characteristics using fuel as rice bran and pongamia methyl ester  

Science Journals Connector (OSTI)

In this study for the first time a nanoceramic Al 2 O 3 was used as a coatingmaterial in the low heat rejection engine concept. Experiments were conducted on single cylinder four stroke water cooled and direct injection diesel engine. First the engine was tested at different load conditions without coating. Then combustion chamber surfaces (cylinder head cylinder liner valves and piston crown face) were coated with nanoceramic material of Al 2 O 3 using plasma spray method. Comparative evaluation on performance and emission characteristics using fuel as rice bran methyl ester pongamia methyl ester and biodiesel/diesel fuel mixtures was studied in the ceramiccoated and uncoated engines under the same running conditions. An increase in engine power and a decrease in specific fuel consumption as well as significant improvements in exhaust gas emissions (except NOx) and smoke density were observed in the ceramiccoated engines compared with those of the uncoated engine.

Ab initio molecular orbital study on the gas phase SN2 reaction F? + \\{CH3Cl\\} ? CH3F + Cl?  

Science Journals Connector (OSTI)

Ab-initio molecular orbital (MO) and direct ab initio dynamics calculations have been applied to the gas phase SN2 reaction F? + \\{CH3Cl\\} ? CH3F + Cl?. Several basis sets were examined in order to select the most convenient and best fitted basis set to that of high-quality calculations. The Hartree–Fock (HF) 3?21+G(d) calculation reasonably represents a potential energy surface calculated at the MP2/6?311++G(2df,2pd) level. A direct ab initio dynamics calculation at the HF/3?21+G(d) level was carried out for the SN2 reaction. A full dimensional ab initio potential energy surface including all degrees of freedom was used in the dynamics calculation. Total energies and gradients were calculated at each time step. Two initial configurations at time zero were examined in the direct dynamics calculations: one is a near collinear collision, and the other is a side-attack collision. It was found that in the near collinear collision almost all total available energy is partitioned into two modes: the relative translational mode between the products (?40%) and the C ? F stretching mode (?60%). The other internal modes of CH3F were still in the ground state. The lifetimes of the early- and late-complexes F? … \\{CH3Cl\\} and FCH3 … Cl? are significantly short enough to dissociate directly to the products. On the other hand, in the side-attack collision, the relative translation energy was about 20% of total available energy.

A comparative study of Al2O3 coated LHR engine characteristic using rice bran and mahua methyl ester as a fuel  

Science Journals Connector (OSTI)

In this study, for the first time, a nano material of Al2O3 was used as ceramic layer in low heat rejection engine concepts. The coating was carried out by plasma spray method on the combustion chamber surfaces (cylinder head, cylinder liner, valves and crown surfaces) of the DI diesel engine. A comparative evaluation of Al2O3 coated engine was carried out between two types of biodiesel (methyl ester of rice bran and mahua oil) and diesel. Experiments were conducted on single cylinder, four strokes, water cooled and direct injection diesel engine. The test run was also repeated for uncoated engine and compared. The results indicated that, an increase in engine power (6.3-11.4%) and decrease in specific fuel consumption (0.8-10.9%), as well as significant improvements in exhaust gas emissions (except NOx) and smoke opacity (19.6-28.9%) were observed in Al2O3 coated engine compared with that of the uncoated engine.

ChIP-seq Identification of Weakly Conserved Heart Enhancers  

SciTech Connect

Accurate control of tissue-specific gene expression plays a pivotal role in heart development, but few cardiac transcriptional enhancers have thus far been identified. Extreme non-coding sequence conservation successfully predicts enhancers active in many tissues, but fails to identify substantial numbers of heart enhancers. Here we used ChIP-seq with the enhancer-associated protein p300 from mouse embryonic day 11.5 heart tissue to identify over three thousand candidate heart enhancers genome-wide. Compared to other tissues studied at this time-point, most candidate heart enhancers are less deeply conserved in vertebrate evolution. Nevertheless, the testing of 130 candidate regions in a transgenic mouse assay revealed that most of them reproducibly function as enhancers active in the heart, irrespective of their degree of evolutionary constraint. These results provide evidence for a large population of poorly conserved heart enhancers and suggest that the evolutionary constraint of embryonic enhancers can vary depending on tissue type.

A PRECESSING JET IN THE CH Cyg SYMBIOTIC SYSTEM  

SciTech Connect

Jets have been detected in only a few symbiotic binaries to date, and CH Cyg is one of them. In 2001, a non-relativistic jet was detected in CH Cyg for the first time in X-rays. We carried out coordinated Chandra, Hubble Space Telescope (HST), and VLA observations in 2008 to study the propagation of this jet and its interaction with the circumbinary medium. We detected the jet with Chandra and HST and determined that the apex has expanded to the south from {approx}300 AU to {approx}1400 AU, with the shock front propagating with velocity <100 km s{sup -1}. The shock front has significantly slowed down since 2001. Unexpectedly, we also discovered a powerful jet in the NE-SW direction, in the X-ray, optical and radio. This jet has a multi-component structure, including an inner jet and a counterjet at {approx}170 AU, and a SW component ending in several clumps extending out to {approx}750 AU. The structure of the jet and the curvature of the outer portion of the SW jet suggest an episodically powered precessing jet or a continuous precessing jet with occasional mass ejections or pulses. We carried out detailed spatial mapping of the X-ray emission and correlation with the optical and radio emission. X-ray spectra were extracted from the central source, inner NE counterjet, and the brightest clump at a distance of {approx}500 AU from the central source. We discuss the initial results of our analyses, including the multi-component spectral fitting of the jet components and of the central source.

Ligand Lone-Pair Influence on Hydrocarbon C-H Activation: A Computational Perspective  

SciTech Connect

Mid to late transition metal complexes that break hydrocarbon C?H bonds by transferring the hydrogen to a heteroatom ligand while forming a metal?alkyl bond offer a promising strategy for C?H activation. Here we report a density functional (B3LYP, M06, and X3LYP) analysis of cis-(acac){sub 2}MX and TpM(L)X (M = Ir, Ru, Os, and Rh; acac = acetylacetonate, Tp = tris(pyrazolyl)borate; X = CH{sub 3}, OH, OMe, NH{sub 2}, and NMe{sub 2}) systems for methane C?H bond activation reaction kinetics and thermodynamics. We address the importance of whether a ligand lone pair provides an intrinsic kinetic advantage through possible electronic d{sub ?}?p{sub ?} repulsions for M?OR and M?NR{sub 2} systems versus M?CH{sub 3} systems. This involves understanding the energetic impact of the X ligand group on ligand loss, C?H bond coordination, and C?H bond cleavage steps as well as understanding how the nucleophilicity of the ligand X group, the electrophilicity of the transition metal center, and cis-ligand stabilization effect influence each of these steps. We also explore how spectator ligands and second- versus third-row transition metal centers impact the energetics of each of these C?H activation steps.

Direct dynamics simulation of dioxetane formation and decomposition via the singlet ·O–O–CH2–CH2 · biradical: Non-RRKM dynamics  

SciTech Connect

Electronic structure calculations and direct chemical dynamics simulations are used to study the formation and decomposition of dioxetane on its ground state singlet potential energy surface. The stationary points for 1O2 + C2H4, the singlet {center_dot}O-O-CH2-CH2{center_dot} biradical, the transition state (TS) connecting this biradical with dioxetane, and the two transition states and gauche {center_dot}O-CH2-CH2-O{center_dot} biradical connecting dioxetane with the formaldehyde product molecules are investigated at different levels of electronic structure theory including UB3LYP, UMP2, MRMP2, and CASSCF and a range of basis sets. The UB3LYP/6-31G* method was found to give representative energies for the reactive system and was used as a model for the simulations. UB3LYP/6-31G* direct dynamics trajectories were initiated at the TS connecting the {center_dot}O-O-CH2-CH2{center_dot} biradical and dioxetane by sampling the TS's vibrational energy levels, and rotational and reaction coordinate energies, with Boltzmann distributions at 300, 1000, and 1500 K. This corresponds to the transition state theory model for trajectories that pass the TS. The trajectories were directed randomly towards both the biradical and dioxetane. A small fraction of the trajectories directed towards the biradical recrossed the TS and formed dioxetane. The remainder formed 1O2 + C2H4 and of these {approx} 40% went directly from the TS to 1O2 + C2H4 without getting trapped and forming an intermediate in the {center_dot}O-O- CH2-CH2{center_dot} biradical potential energy minimum, a non-statistical result. The dioxetane molecules which are formed dissociate to two formaldehyde molecules with a rate constant two orders of magnitude smaller than that predicted by Rice-Ramsperger-Kassel-Marcus theory. The reaction dynamics from dioxetane to the formaldehyde molecules do not follow the intrinsic reaction coordinate or involve trapping in the gauche {center_dot}O-CH2-CH2-O{center_dot} biradical potential energy minimum. Important non-statistical dynamics are exhibited for this reactive system.

The adsorption and surface chemistry CH{sub 3} on Pt(111)  

SciTech Connect

The adsorption and surface chemistry of methyl radicals on Pt(111) has been studied by temperature programmed desorption (TPD), reflection-adsorption infrared reflection spectroscopy (RAIRS), and isotopic tracer experiments. Methyl radicals were introduced on the surface directly from the gas using a methyl radical source based on the pyrolysis of azomethane, CH{sub 3}NNCH{sub 3}. Methyl radicals adsorb with near-unity sticking probability on clean Pt(111) at 150 K to form surface methyl groups detectable by RAIRS. Between 180 K and 300 K the methyl groups react with surface hydrogen to form CH{sub 4} which desorbs from the surface. The hydrogen is derived from adsorption of H{sub 2} and dehydrogenation of adsorbed CH{sub 3}. At high methyl coverages C-C bond formation is observed which leads to the production of surface ethylidyne, {triple_bond}C-CH{sub 3}. Kinetic modeling of the surface reaction will be discussed.

Absolute and site-specific abstraction rate coefficients for reactions of Cl with CH{sub 3}CH{sub 2}OH, CH{sub 3}CD{sub 2}OH, and CD{sub 3}CH{sub 2}OH between 295 and 600 K  

SciTech Connect

Absolute rate coefficients for reactions of Cl atoms with selectively deuterated ethanols have been measured between 295 and 600 K by a laser-photolysis/CW infrared absorption method. Yields of HCl are determined by comparison with the Cl + ethane or Cl + propane reaction, permitting site-specific branching fractions to be derived. Smog chamber experiments with Fourier transform infrared (FTIR) detection are performed to determine products of the room-temperature Cl + C{sub 2}H{sub 5}OH reaction. The rate coefficients for all ethanols display only a slight temperature dependence and can be parameterized by simple Arrhenius expressions: k{sub CH{sub 3}CH{sub 2}OH} = (9.4 {+-} 1.4) x 10{sup {minus}11}e{sup (45 {+-} 32)/T}, k{sub CD{sub 3}CH{sub 2}OH} = (6.6 {+-} 0.9) x 10{sup {minus}11}e{sup (90 {+-} 40)/T}, and k{sub CH{sub 3}CD{sub 2}OH} = (6.9 {+-} 0.7) x 10{sup {minus}11}e{sup ({minus}76 {+-} 40)/T} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} (error bars {+-}2{sigma}). Combining the results from the present work with literature data, the authors recommend k{sub CH{sub 3}CH{sub 2}OH} = (9.5 {+-} 1.9) x 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} at 298 K. The room-temperature contribution of abstraction at the methyl site is found to be 0.07 & 0.02 from FTIR product analysis of the Cl + CH{sub 3}CH{sub 2}OH reaction and 0.08 {+-} 0.02 from laser photolysis/CW infrared absorption measurements (error bars {+-}2{sigma}). Abstraction of the hydroxyl hydrogen is negligible. A small but significant amount of HCl ({nu} = 1) is produced in the Cl + CD{sub 3}CH{sub 2}OH and Cl + CH{sub 3}CH{sub 2}OH reactions at room temperature.

Upper bound of polymeric membranes for mixed-gas CO2/CH4 separations  

Science Journals Connector (OSTI)

Abstract Membrane polymers with high permeability and high selectivity are preferred for gas separations. However, there exists a trade-off or upper bound, i.e., polymers with higher permeability often exhibit lower selectivity, and vice versa. The upper bound for separation of various gas pairs has been empirically drawn and theoretically rationalized using pure-gas data. However, for CO2/CH4 separation, the high pressure CO2 and non-methane hydrocarbons can plasticize polymers, increasing mixed-gas CO2 permeability and decreasing mixed-gas CO2/CH4 selectivity. This study aims to apply a modified free volume theory to interpret CO2/CH4 separation performance in polymeric membranes. The model satisfactorily describes the pure-gas upper bounds for various gas pairs including CO2/CH4, the effect of high pressure CO2 on mixed-gas CO2/CH4 separation properties, and the practical mixed-gas upper bound for CO2/CH4 separations. The CO2 is found to have an estimated glass transition temperature of 108 K. The assumptions of this model are discussed, and future work to improve this model is proposed.

Roles of chemically inequivalent N(CH3)4 ions in phase transition temperatures in [N(CH3)4]2CoCl4 by single-crystal NMR and MAS NMR  

Science Journals Connector (OSTI)

Abstract The temperature dependences of the 1H and 13C spin–lattice relaxation time in the laboratory frame, T1, and in the rotating frame, T1?, in [N(CH3)4]2CoCl4 were measured by static nuclear magnetic resonance (NMR) and magic angle spinning (MAS) NMR. In the ferroelastic phase, 1H T1? underwent molecular motion according to the Bloembergen–Purcell–Pound theory. Two inequivalent ions, a-N(CH3)4 and b-N(CH3)4, were identified by 13C cross polarization (CP)/MAS NMR. On the basis of the 13C NMR results, the existence of two chemically inequivalent a-N(CH3)4 and b-N(CH3)4 ions in the ferroelectric phase and the existence of the ferroelastic twin structure of the N(CH3)4 ions in the ferroelastic phase were discussed.

Observation of CH4 and other Non-CO2 Green House Gas Emissions from California  

SciTech Connect

In 2006, California passed the landmark assembly bill AB-32 to reduce California's emissions of greenhouse gases (GHGs) that contribute to global climate change. AB-32 commits California to reduce total GHG emissions to 1990 levels by 2020, a reduction of 25 percent from current levels. To verify that GHG emission reductions are actually taking place, it will be necessary to measure emissions. We describe atmospheric inverse model estimates of GHG emissions obtained from the California Greenhouse Gas Emissions Measurement (CALGEM) project. In collaboration with NOAA, we are measuring the dominant long-lived GHGs at two tall-towers in central California. Here, we present estimates of CH{sub 4} emissions obtained by statistical comparison of measured and predicted atmospheric mixing ratios. The predicted mixing ratios are calculated using spatially resolved a priori CH{sub 4} emissions and surface footprints, that provide a proportional relationship between the surface emissions and the mixing ratio signal at tower locations. The footprints are computed using the Weather Research and Forecast (WRF) coupled to the Stochastic Time-Inverted Lagrangian Transport (STILT) model. Integral to the inverse estimates, we perform a quantitative analysis of errors in atmospheric transport and other factors to provide quantitative uncertainties in estimated emissions. Regressions of modeled and measured mixing ratios suggest that total CH{sub 4} emissions are within 25% of the inventory estimates. A Bayesian source sector analysis obtains posterior scaling factors for CH{sub 4} emissions, indicating that emissions from several of the sources (e.g., landfills, natural gas use, petroleum production, crops, and wetlands) are roughly consistent with inventory estimates, but livestock emissions are significantly higher than the inventory. A Bayesian 'region' analysis is used to identify spatial variations in CH{sub 4} emissions from 13 sub-regions within California. Although, only regions near the tower are significantly constrained by the tower measurements, CH{sub 4} emissions from the south Central Valley appear to be underestimated in a manner consistent with the under-prediction of livestock emissions. Finally, we describe a pseudo-experiment using predicted CH{sub 4} signals to explore the uncertainty reductions that might be obtained if additional measurements were made by a future network of tall-tower stations spread over California. These results show that it should be possible to provide high-accuracy estimates of surface CH{sub 4} emissions for multiple regions as a means to verify future emissions reductions.

Effects of CH4, H2 and CO2 Mixtures on SI Gas Engine  

Science Journals Connector (OSTI)

Abstract Performance of a four-stroke spark ignition gas engine operated on mixtures of CH4, H2 and CO2 was studied. Experiments were carried out at a constant engine speed of 2,000 rpm and throttle opening of 14% with various equivalence ratios. The results showed that the highest brake power output of 12.5 kW and 35% thermal efficiency were achieved when operated with the mixture of 69.70% CH4, 9.95% H2 and 20.45% CO2 and the equivalence ratios between 1.0 and 0.82.

A facility design for repackaging ORNL CH-TRU legacy waste in Building 3525  

SciTech Connect

For the last 25 years, the Oak Ridge National Laboratory (ORNL) has conducted operations which have generated solid, contact-handled transuranic (CH-TRU) waste. At present the CH-TRU waste inventory at ORNL is about 3400 55-gal drums retrievably stored in RCRA-permitted, aboveground facilities. Of the 3400 drums, approximately 2600 drums will need to be repackaged. The current US Department of Energy (DOE) strategy for disposal of these drums is to transport them to the Waste Isolation Pilot Plant (WIPP) in New Mexico which only accepts TRU waste that meets a very specific set of criteria documented in the WIPP-WAC (waste acceptance criteria). This report describes activities that were performed from January 1994 to May 1995 associated with the design and preparation of an existing facility for repackaging and certifying some or all of the CH-TRU drums at ORNL to meet the WIPP-WAC. For this study, the Irradiated Fuel Examination Laboratory (IFEL) in Building 3525 was selected as the reference facility for modification. These design activities were terminated in May 1995 as more attractive options for CH-TRU waste repackaging were considered to be available. As a result, this document serves as a final report of those design activities.

The microwave spectrum and structure of the CH[sub 3]OH-CO dimer  

SciTech Connect

The reaction mechanism involved in the conversion of methanol to gasoline (MTG) over a zeolite catalyst (MTG process) has generated considerable interest, although much controversy still remains over the particular steps which lead to the formation of the first C-C bond. The rotational spectrum of CH[sub 3]OH-CO has been observed in the region 7--18 GHz with a pulsed-beam Fabry-Perot cavity Fourier-transform microwave spectrometer. In order to obtain detailed structural information the spectra of CH[sub 3]OH, CH[sub 3]OD, CD[sub 3]OH, and CD[sub 3]OD combined with CO and [sup 13]CO were examined. Each of the isotopic species studied exhibits two states, which are interpreted as A and E symmetry states arising from internal rotation of the methyl group. The E-state assignments were verified by observing their first-order Stark effect. The structure of the complex is a bent hydrogen bond of the carbon atom of CO at a distance of 2.41 [angstrom] from the hydroxyl hydrogen of methanol and planar heavy atoms. The effective barrier to internal rotation for CH[sub 3]OH-CO, V[sub 3] = 183.0 cm[sup [minus]1], is one-half of the value for the methanol monomer.

Ultraviolet absorption spectra and kinetics of the self-reaction of CH sub 2 Br and CH sub 2 BrO sub 2 radicals in the gas phase at 298 K. [Accelerated electrons  

SciTech Connect

The ultraviolet absorption spectra of CH{sub 2}Br and CH{sub 2}BrO{sub 2} radicals and the kinetics of their self-reactions have been studied in the gas phase at 298 K by using the pulse radiolysis technique. Absorption cross sections were quantified over the wavelength range 220-350 nm. Measured cross sections near the absorption maxima were {sigma}{sub CH{sub 2}Br}(280 nm) = (6.26 {plus minus} 1.15) {times} 10{sup {minus}18} cm{sup 2} molecule{sup {minus} 1}. Errors represent statistical errors (2{sigma}) together with the authors' estimate of potential systematic errors (10%). The absorption cross-sectional data were then used to derive the observed self-reaction rate constants for reactions 1 and 2, defined as {minus}d(R)/dt = 2k{sub obs}(R){sup 2} (R = CH{sub 2}Br or CH{sub 2}BrO{sub 2}) of CH{sub 2}Br + CH{sub 2}BR {yields} products (1), and CH{sub 2}BrO{sub 2} + CH{sub 2}BrO{sub 2} {yields} products (2) k{sub 1} = (2.93 {plus minus} 0.60) {times} 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} and k{sub 2obs} = (3.26 {plus minus} 0.31) {times} 10{sup {minus}11} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} (quoted errors represent 2{sigma}). These results are discussed with respect to previous studies of the absorption spectra and kinetics of peroxy radicals.

Translational/rotational coupling of the hindered CH 3 quantum-rotor in lithium acetate dihydrate  

Science Journals Connector (OSTI)

The multiplet structure of the rotational-tunneling peaks in the inelastic neutron-scattering spectrum of lithium acetate is widely regarded as evidence of coupled pairs of CH 3 quantum rotors. However our molecular-mechanics study which has no adjustable parameters reveals that rotor/rotor coupling is less important than translational/rotational coupling. In order to remain at a potential-energy minimum during CH 3 group reorientation the center-of-mass of this group follows an almost circular path around its time-average position. The energy levels from this dynamical model reproduce the observed tunneling-transitions reasonably well and the predicted rectangular density distribution of the three methyl H-atoms is in good agreement with that measured by single-crystalneutron diffraction.

Single ionization of CH{sub 4} by bare ions: Fully differential cross sections  

SciTech Connect

A theoretical study of fully differential cross sections for the single ionization of CH{sub 4} by collisions with H{sup +}, He{sup 2+}, and C{sup 6+} ions at energies in the order of MeV/amu is presented. We work in terms of the Born-3DW model, which considers a non-Coulomb central potential for the interaction of the active electron with the molecular core. Results obtained with the Born-3DW model are compared to those obtained with the Born-C3 model, which assumes this potential as purely Coulombic. The anisotropic potential of the CH{sub 4} molecule is smoothed through an angular integration, and results are averaged over all the possible orientations of the target molecule. Results for the lesser bound molecular orbitals (1T and 2A{sub 1}) are presented and discussed for different projectile momentum transfers for the coplanar geometry.

Microwave spectroscopy of Lambda-doublet transitions in the ground state of CH  

E-Print Network (OSTI)

The Lambda-doublet transitions in CH at 3.3 and 0.7 GHz are unusually sensitive to variations in the fine-structure constant and the electron-to-proton mass ratio. We describe methods used to measure the frequencies of these transitions with Hz-level accuracy. We produce a pulsed supersonic beam of cold CH by photodissociation of CHBr3, and we measure the microwave transition frequencies as the molecules propagate through a parallel-plate transmission line resonator. We use the molecules to map out the amplitude and phase of the standing wave field inside the transmission line. We investigate velocity-dependent frequency shifts, showing that they can be strongly suppressed through careful timing of the microwave pulses. We measure the Zeeman and Stark effects of the microwave transitions, and reduce systematic shifts due to magnetic and electric fields to below 1 Hz. We also investigate other sources of systematic uncertainty in the experiment.

Formation and characterization of hydrophobic glass surface treated by atmospheric pressure He/CH4 plasma  

Science Journals Connector (OSTI)

Atmospheric pressure helium plasmas generated in the open air by 13.56?MHz rf power were applied for the glass surface wettability modification. The plasma gas temperature measured by the spectroscopic method was under 400?K which is low enough to treat the samples without thermal damages. The hydrophobicity of the samples determined by the water droplet contact angle method was dependent on the methane gas content and the plasma exposure time. Adding the methane gas by a small amount of 0.25% the contact angle was remarkably increased from 10° to 83° after the 10 s plasma treatment. From the analysis of the treated surface and the plasma it was shown that the deposition of alkane functional groups such as C-H stretch CH2 bend and CH3 bend was one of the contributing factors for the hydrophobicity development. In addition the hydrophobic properties lasted over 2 months even after the single treatment. From the results the atmospheric pressure plasma treatment promises the fast and low-cost method for the thermally-weak surface modification.

58 58 Affected Environment 4.9.1 PLANT COMMUNITIES AND ASSOCIATIONS INEEL lies within a cool desert ecosystem dom- inated by shrub-steppe vegetation. The area is relatively undisturbed, providing important habi- tat for species native to the region. Vegetation and habitat on INEEL can be grouped into six types: shrub-steppe, juniper woodlands, native grasslands, modified ephemeral playas, lava, and wetland-like areas. Figure 4-16 shows these areas. More than 90 percent of INEEL falls within the shrub-steppe vegetation type. The shrub-steppe vegetation type is dominated by sagebrush (Artemisia spp.), saltbush (Atriplex spp.), and rabbitbrush (Chrysothamnus spp.). Grasses found on INEEL include cheatgrass (Bromus tectorum), Indian ricegrass (Oryzopsis hymenoides), wheatgrass (Agropyron spp.), and

Negative ion motion in the mixtures of SF6 with CF4 and CH4-Ar  

Science Journals Connector (OSTI)

This paper deals with the measurement of the mobility of negative ions in the mixtures of SF6 with CF4 and the CH4-Ar (50:50) binary mixture with SF6 contents up to 50%. The pulsed Townsend technique was used to observe the integrated ionic avalanches over a range of the density-reduced electric field E/N for which ionization is either negligible or absent, and attachment processes are significant, leading to the formation of mostly SF6-. The E/N range of measurement was from 1 to 70 Td (1 Td=10-17 V cm2), over which the measured mobilities were found to be almost constant. The mobility of the negative ions was also measured for trace amounts of SF6 in CH4 and Ar and 1% CF4, thereby providing a good value of the mobility of SF6- in these pure gases, in order to test the measured mobilities with Blanc’s law. We have found good agreement, within quoted experimental uncertainties, between calculated and measured values.

CO2 and CH4 Fluxes across Polygon Geomorphic Types, Barrow, Alaska, 2006-2010  

DOE Data Explorer (OSTI)

Carbon flux data are reported as Net Ecosystem Exchange (NEE), Gross Ecosystem Exchange (GEE), Ecosystem Respiration (ER), and Methane (CH4) flux. Measurements were made at 82 plots across various polygon geomorphic classes at research sites on the Barrow Environmental Observatory (BEO), the Biocomplexity Experiment site on the BEO, and the International Biological Program (IBP) site a little west of the BEO. This product is a compilation of data from 27 plots as presented in Lara et al. (2012), data from six plots presented in Olivas et al. (2010); and from 49 plots described in (Lara et al. 2014). Measurements were made during the peak of the growing seasons during 2006 to 2010. At each of the measurement plots (except Olivas et al., 2010) four different thicknesses of shade cloth were used to generate CO2 light response curves. Light response curves were used to normalize photosynthetically active radiation that is diurnally variable to a peak growing season average ~400 umolm-2sec-1. At the Olivas et al. (2010) plots, diurnal patterns were characterized by repeated sampling. CO2 measurements were made using a closed-chamber photosynthesis system and CH4 measurements were made using a photo-acoustic multi-gas analyzer. In addition, plot-level measurements for thaw depth (TD), water table depth (WTD), leaf area index (LAI), and normalized difference vegetation index (NDVI) are summarized by geomorphic polygon type.

Effects of CH{sub 4} and CO on the reduction of nitric oxide to nitrogen in a discharge reactor  

SciTech Connect

Additives are often added to enhance the efficiency of NO removal. This study uses a radio frequency (rf) discharge to consider the effect of added CH{sub 4} and CO to simulated NO/N{sub 2}/O{sub 2}/H{sub 2}O mixtures on the elevation of NO conversion and the reduction of NO into N{sub 2}. The enhancement levels of NO conversion when using various additives were found to be in this order: +CH{sub 4}>+CO>no additive. NO conversion reached 99.3%, 86.2%, and 77.6% when adding CH{sub 4}, CO, and without additive, respectively, at inlet additive/NO molar ratio (R) = 5 and at 120 W. Moreover, the fraction of total N atoms converted from NO into N{sub 2} (F{sub N2}) was very high, reaching 99.4% and 99.5% when adding CH{sub 2}4 and CO, respectively, at R = 1 and at 120 W. The better operating conditions are using CH{sub 4} as the additive at R = 1 and a power of >60 W to reach a higher NO conversion with a higher F{sub N2}. However, it should be noted that this rf plasma approach is not practical at this stage because of its relative low pressure. 25 refs., 2 figs., 3 tabs.

Infrared diode laser studies of the products from the reaction CH{sub 2}({tilde X}{sup 3}B{sub 1}) + O{sub 2} and from the near-UV photolysis of CH{sub 3}NCS  

SciTech Connect

Absolute yields of CO, CO{sub 2}, and H{sub 2}CO formed in reaction of triplet methylene ({tilde X} {sup 3}B{sub 1} {triple_bond} CH{sub 2}) with O{sub 2} were determined using a flash kinetic spectrometer. CH{sub 2} radicals were generated by excimer laser photolysis of ketene and product formation was monitored by time-resolved infrared diode laser absorption. Reaction was carried out in a static gas cell at room temperature at 1--25 torr. Measured product yields were CO, 0.34 {plus_minus} 0.06; CO{sub 2}, 0.40 {plus_minus} 0.08 H{sub 2}CO, 0.16 {plus_minus} 0.04. Rate constants for production of CO and CO{sub 2} were equivalent to the published rate constant for removal of CH{sub 2}. Indirect evidence indicated that yield of OH is 0.30 {plus_minus} 0.05. Ultraviolet spectrum of methyl isothiocyanate (CH{sub 3}NCS {triple_bond} MITC) and quantum yield for dissociation into methyl isocyanide (CH{sub 3}NC) and atomic sulfur at 308 nm, {Phi} 0.98 {plus_minus} 0.24, were measured. MITC is widely used as a fumigant and readily enters the atmosphere during and after application. Results indicate that photodissociation by sunlight is an effective pathway for removal of MITC from atmosphere. A mechanism is proposed to account for the observed formation of methyl isocyanate (CH{sub 3}NCO) as a secondary product in controlled laboratory studies.

Quantitative Visualization of ChIP-chip Data by Using Linked Views  

SciTech Connect

Most analyses of ChIP-chip in vivo DNA binding have focused on qualitative descriptions of whether genomic regions are bound or not. There is increasing evidence, however, that factors bind in a highly overlapping manner to the same genomic regions and that it is quantitative differences in occupancy on these commonly bound regions that are the critical determinants of the different biological specificity of factors. As a result, it is critical to have a tool to facilitate the quantitative visualization of differences between transcription factors and the genomic regions they bind to understand each factor's unique roles in the network. We have developed a framework which combines several visualizations via brushing-and-linking to allow the user to interactively analyze and explore in vivo DNA binding data of multiple transcription factors. We describe these visualization types and also provide a discussion of biological examples in this paper.

Theoretical study on collision dynamics of H{sup +} + CH{sub 4} at low energies  

SciTech Connect

In this work we make an investigation on collision dynamics of H{sup +} + CH{sub 4} at 30 eV by using time-dependent density functional theory coupled with molecular dynamics approach. All possible reactions are presented based on 9 incident orientations. The calculated fragment intensity is in nice agreement with experimental results. The mechanism of reaction transition for dissociation and proton exchange processes is explained by the intra-molecule energy transfer. However, the energy loss of the proton is in poor agreement with experimental results. The discrepancy is attributed to the mean-field treatment of potential surface. We also studied the dependence on initial velocity of both proton and methane. In addition, we find that for dynamical evolution a different self-interaction correction (SIC) may lead to different results, but with respect to the position of rainbow angle, average-density SIC seems to have reasonable correction.

Hybrid Quantum Mechanical/Molecular Mechanics Study of the SN2 Reaction of CH3Cl+OH? in Water  

SciTech Connect

The SN2 mechanism for the reaction of CH3Cl + OH? in aqueous solution was investigated using combined quantum mechanical and molecular mechanics methodology. We analyzed structures of reactant, transition and product states along the reaction pathway. The free energy profile was calculated using the multi-layered representation with the DFT and CCSD(T) level of theory for the quantum-mechanical description of the reactive region. Our results show that the aqueous environment has a significant impact on the reaction process. We find that solvation energy contribution raises the reaction barrier by ~18.9 kcal/mol and the reaction free energy by ~24.5 kcal/mol. The presence of the solvent also induces perturbations in the electronic structure of the solute leading to an increase of 3.5 kcal/mol for the reaction barrier and a decrease of 5.6 kcal/mol for the reaction free energy respectively. Combining the results of two previous calculation results on CHCl3 + OH? and CH2Cl2 + OH? reactions in water, we demonstrate that increase in the chlorination of the methyl group (from CH3Cl to CHCl3) is accompanied by the decrease in the free energy reaction barrier, with the CH3Cl + OH? having the largest barrier among the three reactions.

DISCOVERY OF THE METHOXY RADICAL, CH{sub 3}O, TOWARD B1: DUST GRAIN AND GAS-PHASE CHEMISTRY IN COLD DARK CLOUDS  

SciTech Connect

We report on the discovery of the methoxy radical (CH{sub 3}O) toward the cold and dense core B1-b based on the observation, with the IRAM 30 m radio telescope, of several lines at 3 and 2 mm wavelengths. Besides this new molecular species we also report on the detection of many lines arising from methyl mercaptan (CH{sub 3}SH), formic acid (HCOOH), propynal (HCCCHO), acetaldehyde (CH{sub 3}CHO), dimethyl ether (CH{sub 3}OCH{sub 3}), methyl formate (CH{sub 3}OCOH), and the formyl radical (HCO). The column density of all these species is {approx_equal}10{sup 12} cm{sup -2}, corresponding to abundances of {approx_equal}10{sup -11}. The similarity in abundances for all these species strongly suggest that they are formed on the surface of dust grains and ejected to the gas phase through non-thermal desorption processes, most likely cosmic rays or secondary photons. Nevertheless, laboratory experiments indicate that the CH{sub 3}O isomer released to the gas phase is CH{sub 2}OH rather than the methoxy one. Possible gas-phase formation routes to CH{sub 3}O from OH and methanol are discussed.

Electrophilic, Ambiphilic, and Nucleophilic C-H bond Activation: Understanding the electronic continuum of C-H bond activation through transition-state and reaction pathway interaction energy decompositions  

SciTech Connect

The potential energy and interaction energy profiles for metal- and metal?ligand-mediated alkane C?H bond activation were explored using B3LYP density functional theory (DFT) and the absolutely localized molecular orbital energy decomposition analysis (ALMO-EDA). The set of complexes explored range from late transition metal group 10 (Pt and Pd) and group 11 (Au) metal centers to group 7?9 (Ir, Rh, Ru, and W) metal centers as well as a group 3 Sc complex. The coordination geometries, electron metal count (d{sup 8}, d{sup 6}, d{sup 4}, and d{sup 0}), and ligands (N-heterocycles, O-donor, phosphine, and Cp*) are also diverse. Quantitative analysis using ALMO-EDA of both directions of charge-transfer stabilization (occupied to unoccupied orbital stabilization) energies between the metal?ligand fragment and the coordinated C?H bond in the transition state for cleavage of the C?H bond allows classification of C?H activation reactions as electrophilic, ambiphilic, or nucleophilic on the basis of the net direction of charge-transfer energy stabilization. This bonding pattern transcends any specific mechanistic or bonding paradigm, such as oxidative addition, ?-bond metathesis, or substitution. Late transition metals such as Au(III), Pt(II), Pd(II), and Rh(III) metal centers with N-heterocycle, halide, or O-donor ligands show electrophilically dominated reaction profiles with forward charge-transfer from the C?H bond to the metal, leading to more stabilization than reverse charge transfer from the metal to the C?H bond. Transition states and reaction profiles for d{sup 6} Ru(II) and Ir(III) metals with Tp and acac ligands were found to have nearly equal forward and reverse charge-transfer energy stabilization. This ambiphilic region also includes the classically labeled electrophilic cationic species Cp*(PMe{sub 3})Ir(Me). Nucleophilic character, where the metal to C?H bond charge-transfer interaction is most stabilizing, was found in metathesis reactions with W(II) and Sc(III) metal center complexes in reactions as well as late transition metal Ir(I) and Rh(I) pincer complexes that undergo C?H bond insertion. Comparison of pincer ligands shows that the PCP ligand imparts more nucleophilic character to an Ir metal center than a deprotonated PNP ligand. The PCP and POCOP ligands do not show a substantial difference in the electronics of C?H activation. It was also found that Rh(I) is substantially more nucleophilic than Ir(I). Lastly, as a qualitative approximation, investigation of transition-state fragment orbital energies showed that relative frontier orbital energy gaps correctly reflect electrophilic, ambiphilic, or nucleophilic charge-transfer stabilization patterns.

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 mol–1, 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 mol–1) 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 mol–1 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 mol–1. 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.

Direct ab initio molecular dynamics study on a SN2 reaction OH? + CH3Cl ? CH3OH + Cl?: Effect of non-zero impact parameter on the reaction dynamics  

Science Journals Connector (OSTI)

Direct ab initio molecular dynamics (MD) calculations have been applied to a SN2 reaction OH? + CH3Cl ? CH3OH + Cl?. The collision dynamics with non-zero impact parameters were treated in the present study, and the results are compared with the near collinear collision dynamics previously reported by us [H. Tachikawa, M. Igarashi, T. Ishibashi, J. Phys. Chem. A 106 (2002) 10977]. The collision energy was fixed to 25 kcal/mol. The product state distribution obtained for the non-zero impact parameter collision dynamics was slightly different from that of the collinear collision. The distribution of relative translational energy between products Cl? and CH3OH in the non-zero impact parameter collision dynamics was shifted to higher energy region from that of collinear collision. Also, it was found that the mean translational energy of the product has a maximum at non-zero impact parameter (b = 0.6–1.2 Ĺ). The reaction mechanism is discussed on the basis of theoretical results.

Polyacetylene, (CH)/sub x/, as an emerging material for solar cell applications. Final technical report, March 19, 1979-March 18, 1980  

SciTech Connect

Despite great theoretical and technological interest in polyacetylene, (CH)/sub x/, the basic features of its band structure have not been unambiguously resolved. Since photoconductivity and optical absorption data have frequently been used to infer information on the band structure of semiconductors, such measurements were carried out on (CH)/sub x/. The main results of an extensive study of the photoconductivity (..delta.. sigma/sub ph/) and absorption coefficient (..cap alpha..) in (CH)/sub x/ are presented. The absence of photoconductivity in cis-(CH)/sub x/, despite the similarity in optical properties indicates that ..delta.. sigma/sub ph/ in trans-(CH)/sub x/ is induced by isomerization. It is found that isomerization generates states deep inside the gap that act as safe traps for minority carriers and thereby enhance the photoconductivity. Compensation of trans-(CH)/sub x/ with ammonia appears to decrease the number of safe traps, whereas acceptor doping increases their number. Thus, chemical doping can be used to control the photoconductive response. The energy of safe traps inside the gap is independent of the process used to generate them; indicative of an intrinsic localized defect level in trans-(CH)/sub x/. A coherent picture based on the soliton model can explain these results, including the safe trapping.

Enforcement Letter, September 6, 2007, CH2M Hill Hanford Group Potential Violations of Nuclear Safety Requirements  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

6, 2007 6, 2007 Mr. John Fulton Chief Executive Officer CH2M Hill Hanford Group, Inc. 2440 Stevens Drive Richland, Washington 99352 Dear Mr. Fulton: The Department of Energy (DOE) held an Enforcement Conference on August 29, 2006, with CH2M Hill Hanford Group (CHG) to discuss potential violations of nuclear safety requirements described in our Investigation Summary Report dated July 26, 2006. At that time, DOE elected to defer a decision on a potential quality improvement violation related to recurring radiological events and deficiencies in the identification and control of radiological hazards at the Tank Farms. This decision was based upon the fact that CHG senior management had initiated radiological work improvements but insufficient data was available to assess their effectiveness.

THE POSSIBLE INTERSTELLAR ANION CH{sub 2}CN{sup -}: SPECTROSCOPIC CONSTANTS, VIBRATIONAL FREQUENCIES, AND OTHER CONSIDERATIONS  

SciTech Connect

The A {sup 1}B{sub 1} Leftwards-Open-Headed-Arrow X-tilde{sup 1}A' excitation into the dipole-bound state of the cyanomethyl anion (CH{sub 2}CN{sup -}) has been hypothesized as the carrier for one diffuse interstellar band. However, this particular molecular system has not been detected in the interstellar medium even though the related cyanomethyl radical and the isoelectronic ketenimine molecule have been found. In this study, we are employing the use of proven quartic force fields and second-order vibrational perturbation theory to compute accurate spectroscopic constants and fundamental vibrational frequencies for X-tilde{sup 1} A' CH{sub 2}CN{sup -} in order to assist in laboratory studies and astronomical observations.

Current status and development of membranes for CO2/CH4 separation: A review  

Science Journals Connector (OSTI)

Carbon dioxide (CO2) is a greenhouse gas found primarily as a main combustion product of fossil fuel as well as a component in natural gas, biogas and landfill gas. The interest to remove CO2 from those gas streams to obtain fuel with enhanced energy content and prevent corrosion problems in the gas transportation system, in addition to CO2 implications to the climate change, has driven the development of CO2 separation process technology. One type of technology which has experienced substantial growth, breakthroughs and advances during past decades is membrane-based technology. The attractive features offered by this technology include high energy efficiency, simplicity in design and construction of membrane modules and environmental compatibility. The objective of this review is to overview the different types of membranes available for use including their working principles, current status and development which form the primary determinants of separation performance and efficiency. The emphasis is toward CO2/CH4 separation, considering its substantial and direct relevance to the gas industry. To this end, discussion is made to cover polymeric gas permeation membranes; CO2-selective facilitated transport membranes, hollow fiber gas–liquid membrane contactors, inorganic membranes and mixed matrix membranes. The market for CO2 separation is currently dominated by polymeric membranes due to their relatively low manufacturing cost and processing ability into flat sheet and hollow fiber configurations as well as well-documented research studies. While there have been immensely successful membrane preparation and development techniques with consequential remarkable performance for each type of membrane. Each type of membrane brings associated advantages and drawbacks related to the characteristic transport mechanism for specific application conditions. Inorganic membranes, for example, are very suitable for high temperature CO2 separation in excess of 400 °C while all other membranes can be applied at lower temperatures. The recent emergence of mixed matrix membranes has allowed the innovative approach to combine the advantages offered by inorganic and polymeric materials.

Final LDRD report : development of sample preparation methods for ChIPMA-based imaging mass spectrometry of tissue samples.  

SciTech Connect

The objective of this short-term LDRD project was to acquire the tools needed to use our chemical imaging precision mass analyzer (ChIPMA) instrument to analyze tissue samples. This effort was an outgrowth of discussions with oncologists on the need to find the cellular origin of signals in mass spectra of serum samples, which provide biomarkers for ovarian cancer. The ultimate goal would be to collect chemical images of biopsy samples allowing the chemical images of diseased and nondiseased sections of a sample to be compared. The equipment needed to prepare tissue samples have been acquired and built. This equipment includes an cyro-ultramicrotome for preparing thin sections of samples and a coating unit. The coating unit uses an electrospray system to deposit small droplets of a UV-photo absorbing compound on the surface of the tissue samples. Both units are operational. The tissue sample must be coated with the organic compound to enable matrix assisted laser desorption/ionization (MALDI) and matrix enhanced secondary ion mass spectrometry (ME-SIMS) measurements with the ChIPMA instrument Initial plans to test the sample preparation using human tissue samples required development of administrative procedures beyond the scope of this LDRD. Hence, it was decided to make two types of measurements: (1) Testing the spatial resolution of ME-SIMS by preparing a substrate coated with a mixture of an organic matrix and a bio standard and etching a defined pattern in the coating using a liquid metal ion beam, and (2) preparing and imaging C. elegans worms. Difficulties arose in sectioning the C. elegans for analysis and funds and time to overcome these difficulties were not available in this project. The facilities are now available for preparing biological samples for analysis with the ChIPMA instrument. Some further investment of time and resources in sample preparation should make this a useful tool for chemical imaging applications.

Optical and electrical characterization of an atmospheric pressure microplasma jet for Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures  

SciTech Connect

A rf microplasma jet working at atmospheric pressure has been characterized for Ar, He, and Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures. The microdischarge has a coaxial configuration, with a gap between the inner and outer electrodes of 250 {mu}m. The main flow runs through the gap of the coaxial structure, while the reactive gases are inserted through a capillary as inner electrode. The discharge is excited using a rf of 13.56 MHz, and rms voltages around 200-250 V and rms currents of 0.4-0.6 A are obtained. Electron densities around 8x10{sup 20} m{sup -3} and gas temperatures lower than 400 K have been measured using optical emission spectroscopy for main flows of 3 slm and inner capillary flows of 160 SCCM. By adjusting the flows, the flow pattern prevents the mixing of the reactive species with the ambient air in the discharge region, so that no traces of air are found even when the microplasma is operated in an open atmosphere. This is shown in Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} plasmas, where no CO and CN species are present and the optical emission spectroscopy spectra are mainly dominated by CH and C{sub 2} bands. The ratio of these two species follows different trends with the amount of precursor for Ar/CH{sub 4} and Ar/C{sub 2}H{sub 2} mixtures, showing the presence of distinct chemistries in each of them. In Ar/C{sub 2}H{sub 2} plasmas, CH{sub x} species are produced mainly by electron impact dissociation of C{sub 2}H{sub 2} molecules, and the CH{sub x}/C{sub 2}H{sub x} ratio is independent of the precursor amount. In Ar/CH{sub 4} mixtures, C{sub 2}H{sub x} species are formed mainly by recombination of CH{sub x} species through three-body reactions, so that the CH{sub x}/C{sub 2}H{sub x} ratio depends on the amount of CH{sub 4} present in the mixture. All these properties make our microplasma design of great interest for applications such as thin film growth or surface treatment.

Photon production from collisions of 100–350-keV positive ions with CO, CF4, and CH4  

Science Journals Connector (OSTI)

Various photon emissions from collisions of H+, H2+, and He+ in the 100–350-keV energy range with targets of CO, CF4, and CH4 were studied. The wavelength range of the investigation ran from 2000 to 7000 Ĺ. Photon-emission cross sections were measured for all significant features. The cross-section data were compared to the Bethe-Born theory through the use of Fano plots. The results show that the theory could be applicable in the case of the CO target, but is probably not applicable to the tetrahedral molecular targets as the emissions are from dissociated atoms.

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.

Atmospheric chemistry of HFC-143a: Spectrokinetic investigation of the CF[sub 3]CH[sub 2]O[sub 2][center dot] radical, its reactions with NO and NO[sub 2], and the fate of CF[sub 3]CH[sub 2]O  

SciTech Connect

The ultraviolet absorption spectrum of CF[sub 3]CH[sub 2]O[sub 2] radicals, the kinetics of their self-reaction, and their reactions with NO and NO[sub 2] have been studied in the gas phase at 296 K using a pulse radiolysis technique. A long path-length Fourier transform infrared technique was used to study the fate of CF[sub 3]CH[sub 2]O radicals. Absorption cross sections were quantified over the wavelength range 220-300 nm. At 250 nm, [sigma](CF[sub 3]CH[sub 2]O[sub 2]) = (2.73 [+-] 0.31) [times] 10[sup [minus]18] molecule[sup [minus]1]. By monitoring the rate of NO[sub 2] formation, k[sub 4] = (1.2 [+-] 0.3) [times] 10[sup [minus]11] cm[sup 3] molecule[sup [minus]1] s[sup [minus]1] was found for the reaction of CF[sub 3]CH[sub 2]O[sub 2] radical with NO. The reaction of CF[sub 3]CH[sub 2]O[sub 2] radicals with NO gives CF[sub 3]CH[sub 2]O radicals. In the atmosphere, >99.33% of the CF[sub 3]CH[sub 2]O radicals react with O[sub 2] to give CF[sub 3]CHO. By monitoring the rate of NO[sub 2] decay, k[sub 5] = (5.8 [+-] 1.1) [times] 10[sup [minus]12] cm[sup 3] molecule[sup [minus]1] s[sup [minus]1] was found for the reaction of CF[sub 3]CH[sub 2]O[sub 2] radical with NO[sub 2]. The results are discussed with respect to the atmospheric chemistry of CF[sub 3]CH[sub 3] (HFC-143a). 34 refs., 12 figs., 1 tab.

Temperature dependence of the rate constant for the HO/sub 2/ + CH/sub 3/O/sub 2/ gas-phase reaction  

SciTech Connect

The temperature dependence of the reaction between hydroperoxy and methylperoxy radicals was measured in a flash photolysis ultraviolet absorption apparatus over the temperature range 228-380 K: HO/sub 2/ + CH/sub 3/O/sub 2/ ..-->.. CH/sub 3/O/sub 2/H + O/sub 2/ (1). The data, represented by the Arrhenius expression k/sub 1/ = (3.0 +/- 1.2) x 10/sup -13/ exp((720 +/- 100)/T) cm/sup 3/ molecule/sup -1/ s/sup -1/, are compared to earlier results and discussed in terms of the reaction mechanism. Due to overlapping absorptions of the two radicals and deviations of the complex reaction system from both pseudo-first-order and pseudo-second-order behavior, the rate constants were determined from a detailed modeling of the radical decay curves. A sensitivity analysis of the rate constant determination procedure to the assumed radical absorption cross sections and correlated changes in the rate constants for the HO/sub 2/ and CH/sub 3/O/sub 2/ self-reactions was performed, and the results are reported. The present results were also used to assess the effects of secondary chemistry in the authors measurements of the temperature dependence of the rate constant of the CH/sub 3/O/sub 2/ + CH/sub 3/O/sub 2/ reaction, and the revised Arrhenius parameters are presented.

Adsorption Kinetics of CO2, CH4, and their Equimolar Mixture on Coal from the Black Warrior Basin, West-Central Alabama  

SciTech Connect

Laboratory experiments were conducted to investigate the adsorption kinetic behavior of pure and mixed gases (CO2, CH4, approximately equimolar CO2 + CH4 mixtures, and He) on a coal sample obtained from the Black Warrior Basin at the Littleton Mine (Twin Pine Coal Company), Jefferson County, west-central Alabama. The sample was from the Mary Lee coal zone of the Pottsville Formation (Lower Pennsylvanian). Experiments with three size fractions (45-150 m, 1-2 mm, and 5-10 mm) of crushed coal were performed at 40 C and 35 C over a pressure range of 1.4 6.9 MPa to simulate coalbed methane reservoir conditions in the Black Warrior Basin and provide data relevant for enhanced coalbed methane recovery operations. The following key observations were made: (1) CO2 adsorption on both dry and water-saturated coal is much more rapid than CH4 adsorption; (2) water saturation decreases the rates of CO2 and CH4 adsorption on coal surfaces, but it appears to have minimal effects on the final magnitude of CO2 or CH4 adsorption if the coal is not previously exposed to CO2; (3) retention of adsorbed CO2 on coal surfaces is significant even with extreme pressure cycling; and (4) adsorption is significantly faster for the 45-150 m size fraction compared to the two coarser fractions.

FT-IR product studies of the Cl-initiated oxidation of CH{sub 3}Cl in the presence of NO  

SciTech Connect

The deleterious effect of chlorine chemistry on stratospheric ozone levels is now well documented. The Cl-atom initiated oxidation of CH{sub 3}Cl has been studied at 296 K using two different FTIR/environmental chamber systems. In the presence of NO, the carbon-bearing products observed are HCOCl, HCHO, and CO, with yields in 700 Torr of air of (56 {+-} 10), (32 {+-} 6), and (12 {+-} 5)%, respectively. This product distribution is different from previous studies conducted in the absence of NO, in which a nearly 100% yield of HCOCl was obtained. The different product distribution observed in the presence of NO is attributed to the formation and subsequent decomposition of chemically activated CH{sub 2}ClO radicals, formed in the exothermic reaction of CH{sub 2}ClO{sub 2} with NO.

Communication: Imaging the effects of the antisymmetric-stretching excitation in the O({sup 3}P) + CH{sub 4}(v{sub 3} = 1) reaction  

SciTech Connect

Effects of one-quantum excitation of the antisymmetric-stretching mode of CH{sub 4}(v{sub 3} = 1) on the O({sup 3}P) + CH{sub 4} reaction were studied in a crossed-beam, ion-imaging experiment. In the post-threshold region, we found that (1) the product state distributions are dominated by the CH{sub 3}(0{sub 0}) + OH(v{sup ?} = 1) pair, (2) the product angular distributions extend toward sideways from the backward dominance of the ground-state reaction, and (3) vibrational excitation exerts a positive effect on reactivity, but translational energy is more efficient in promoting the rate of this central-barrier reaction. All major findings agree reasonably well with recent theoretical results. Some remaining questions are pointed out.

Unusual defect physics in CH{sub 3}NH{sub 3}PbI{sub 3} perovskite solar cell absorber  

SciTech Connect

Thin-film solar cells based on Methylammonium triiodideplumbate (CH{sub 3}NH{sub 3}PbI{sub 3}) halide perovskites have recently shown remarkable performance. First-principle calculations show that CH{sub 3}NH{sub 3}PbI{sub 3} has unusual defect physics: (i) Different from common p-type thin-film solar cell absorbers, it exhibits flexible conductivity from good p-type, intrinsic to good n-type depending on the growth conditions; (ii) Dominant intrinsic defects create only shallow levels, which partially explain the long electron-hole diffusion length and high open-circuit voltage in solar cell. The unusual defect properties can be attributed to the strong Pb lone-pair s orbital and I p orbital antibonding coupling and the high ionicity of CH{sub 3}NH{sub 3}PbI{sub 3}.

Investigations of a Low-swirl Injector withH2 and CH4 at Gas Investigations of a Low-swirl Injector withH2 and CH4 at Gas Turbine Conditions Title Laboratory Investigations of a Low-swirl Injector withH2 and CH4 at Gas Turbine Conditions Publication Type Journal Article Year of Publication 2009 Authors Cheng, Robert K., David Littlejohn, P. A. Strakey, and T. Sidwell Journal Science Direct Abstract Laboratory experiments were conducted at gas turbine and atmospheric conditions (0.101 < P0 < 0.810 MPa, 298 < T0 < 580K, 18 < U0 < 60 m/s) to characterize the overall behaviors and emissions of the turbulent premixed flames produced by a low-swirl injector (LSI) for gas turbines. The objective was to investigate the effects of hydrogen on the combustion processes for the adaptation to gas turbines in an IGCC power plant. The experiments at high pressures and temperatures showed that the LSI can operate with 100% H2 at up to f = 0.5 and has a slightly higher flashback tolerance than an idealized high-swirl design. With increasing H2 fuel concentration, the lifted LSI flame begins to shift closer to the exit and eventually attaches to the nozzle rim and assumes a different shape at 100% H2. The STP experiments show the same phenomena. The analysis of velocity data from PIV shows that the stabilization mechanism of the LSI remains unchanged up to 60% H2. The change in the flame position with increasing H2 concentration is attributed to the increase in the turbulent flame speed. The NOx emissions show a log linear dependency on the adiabatic flame temperature and the concentrations are similar to those obtained previously in a LSI prototype developed for natural gas. These results show that the LSI exhibits the same overall behaviors at STP and at gas turbine conditions. Such insight will be useful for scaling the LSI to operate at IGCC conditions.

ELECTRON IRRADIATION OF KUIPER BELT SURFACE ICES: TERNARY N{sub 2}-CH{sub 4}-CO MIXTURES AS A CASE STUDY  

SciTech Connect

The space weathering of icy Kuiper Belt Objects was investigated in this case study by exposing methane (CH{sub 4}) and carbon monoxide (CO) doped nitrogen (N{sub 2}) ices at 10 K to ionizing radiation in the form of energetic electrons. Online and in situ Fourier transform infrared spectroscopy was utilized to monitor the radiation-induced chemical processing of these ices. Along with isocyanic acid (HNCO), the products could be mainly derived from those formed in irradiated binary ices of the N{sub 2}-CH{sub 4} and CO-CH{sub 4} systems: nitrogen-bearing products were found in the form of hydrogen cyanide (HCN), hydrogen isocyanide (HNC), diazomethane (CH{sub 2}N{sub 2}), and its radical fragment (HCN{sub 2}); oxygen-bearing products were of acetaldehyde (CH{sub 3}CHO), formyl radical (HCO), and formaldehyde (H{sub 2}CO). As in the pure ices, the methyl radical (CH{sub 3}) and ethane (C{sub 2}H{sub 6}) were also detected, as were carbon dioxide (CO{sub 2}) and the azide radical (N{sub 3}). Based on the temporal evolution of the newly formed products, kinetic reaction schemes were then developed to fit the temporal profiles of the newly formed species, resulting in numerical sets of rate constants. The current study highlights important constraints on the preferential formation of isocyanic acid (HNCO) over hydrogen cyanide (HCN) and hydrogen isocyanide (HNC), thus guiding the astrobiological and chemical evolution of those distant bodies.

Complete Phase I Tests As Described in the Multi-lab Test Plan for the Evaluation of CH3I Adsorption on AgZ  

SciTech Connect

Silver-exchanged mordenite (AgZ) has been identified as a potential sorbent for iodine present in the off-gas streams of a used nuclear fuel reprocessing facility. In such a facility, both elemental and organic forms of iodine are released from the dissolver in gaseous form. These species of iodine must be captured with high efficiency for a facility to avoid radioactive iodine release above regulatory limits in the gaseous effluent of the plant. Studies completed at Idaho National Laboratory (INL) examined the adsorption of organic iodine in the form of CH3I by AgZ. Upon breakthrough of the feed gas through the sorbent bed, elemental iodine was observed in the effluent stream, despite the fact that the only source of iodine in the system was the CH3I in the feed gas.1 This behavior does not appear to have been reported previously nor has it been independently confirmed. Thus, as a result of these prior studies, multiple knowledge gaps relating to the adsorption of CH3I by AgZ were identified, and a multi-lab test plan, including Oak Ridge National Laboratory (ORNL), INL, Pacific Northwest National Laboratory (PNNL), and Sandia National Laboratories, was formulated to address each in a systematic way.2 For this report, the scope of work for ORNL was further narrowed to three thin-bed experiments that would characterize CH3I adsorption onto AgZ in the presence of water, NO, and NO2. Completion of these three-thin bed experiments demonstrated that organic iodine in the form of CH3I was adsorbed by reduced silver mordenite (Ag0Z) to a 50% higher loading than that of I2 when adsorbed from a dry air stream. Adsorption curves suggest different adsorption mechanisms for I2 and CH3I. In the presence of NO and NO2 gas, the loading of CH3I onto Ag0Z is suppressed and may be reversible. Further, the presence of NO and NO2 gas appears to oxidize CH3I to I2; this is indicated by an adsorption curve similar to that of I2 on Ag0Z. Finally, the loss of organic iodine loading capacity by Ag0Z in the presence of NOx is unaffected by the addition of water vapor to the gas stream; no marked additional loss in capacity or retention was observed.

Orientational effects in the direct Cl? + \\{CH3Cl\\} SN2 reaction at elevated collision energies: hard-ovoid line-of-centers collision model  

Science Journals Connector (OSTI)

The hard-sphere line-of-centers collision model can be extended analytically to include the orientational dependence of both the energy barrier and the critical distance of approach. This hard-ovoid line-of-centers model is applied to the translational activation of the bimolecular nucleophilic substitution (SN2) reaction, Cl? + \\{CH3Cl\\} ? ClCH3 + Cl?, for which a direct reaction mechanism was found in recent classical trajectory calculations. The model is compared with recent experiments and the classical trajectory calculations.

Time-Resolved Quantitative Measurement of OH HO2 and CH2O in Fuel Oxidation Reactions by High Resolution IR Absorption Spectroscopy.  

SciTech Connect

Combined with a Herriott-type multi-pass slow flow reactor, high-resolution differential direct absorption spectroscopy has been used to probe, in situ and quantitatively, hydroxyl (OH), hydroperoxy (HO 2 ) and formaldehyde (CH 2 O) molecules in fuel oxidation reactions in the reactor, with a time resolution of about 1 micro-second. While OH and CH 2 O are probed in the mid-infrared (MIR) region near 2870nm and 3574nm respectively, HO 2 can be probed in both regions: near-infrared (NIR) at 1509nm and MIR at 2870nm. Typical sensitivities are on the order of 10 10 - 10 11 molecule cm -3 for OH at 2870nm, 10 11 molecule cm -3 for HO 2 at 1509nm, and 10 11 molecule cm -3 for CH 2 O at 3574nm. Measurements of multiple important intermediates (OH and HO 2 ) and product (CH 2 O) facilitate to understand and further validate chemical mechanisms of fuel oxidation chemistry.

Closed three-center carbon-hydrogen-metal interaction. A neutron diffraction study of HFe/sub 4/(eta/sup 2/-CH)(CO)/sub 12/  

SciTech Connect

The crystal and molecular structure of HFe/sub 4/(eta/sup 2/-CH)(CO)/sub 12/ has been determined at 173 K by x-ray diffraction and at 26 K by neutron diffraction techniques. The complex crystallized in the monoclinic space group with unit-cell dimensions of a = 8.694 (1) A, b = 32.920 (6) A, c = 13.757 (3) A, ..beta.. = 112.95 (1)/sup 0/, and V = 3625.7 A/sup 3/ at 26 K with Z = 8. Full-matrix least-squares refinement of the neutron data gave R(F/sub 0/) = 0.060 and R/sub w/(F/sub 0//sup 2/) = 0.079 for all 5663 data. The goodness-of-fit, with a data to parameter ratio of 10.1:1, was 1.876. The only significant structural differences in the two unique molecules of the asymmetric unit were the intermolecular contacts. The iron atoms were arranged in a butterfly conformation with a C-H group nestled between the wings. The most significant structural finding was a true C-H-Fe three-center interaction, containing both a very short Fe-H distance of 1.753 (4) A (1.747 (4) A, second molecule) and the longest reported C-H bond distance, 1.191 (4) A (1.176 (4) A). The results have been discussed in relation to the origin and nature of this C-H-Fe three-center interaction, the activation of C-H bonds in catalysis, and possible eta/sup 2/ bonding of a C-H fragment at a metal surface.

Physical properties of selected block Argonne Premium bituminous coal related to CO2, CH4, and N2 adsorption  

Science Journals Connector (OSTI)

CO2, CH4, and N2 adsorption and gas-induced swelling were quantified for block Blind Canyon, Pittsburgh #8 and Pocahontas Argonne Premium coals that were dried and structurally relaxed at 75 °C in vacuum. Strain measurements were made perpendicular and parallel to the bedding plane on ~ 7 × 7 × 7 mm3 coal blocks and gravimetric sorption measurements were obtained simultaneously on companion coal blocks exposed to the same gaseous environment. The adsorption amount and strain were determined after equilibration at P  ? 1.8 MPa. There is a strong non-linear correlation between strain and the quantity of gas adsorbed and the results for all gases and coals studied follow a common pattern. The dependence of the coal matrix shrinkage/swelling coefficient (Cgc) on the type and quantity of gas adsorbed is seen by plotting the ratio between the strain and the adsorbate concentration against the adsorbate concentration. In general, Cgc increases with increasing adsorbate concentration over the range of ~ 0.1 to 1.4 mmol/g. Results from the dried block coals are compared to CO2 experiments using native coals with an inherent level of moisture as received. The amount of CO2 adsorbed using native coals (assuming no displacement of H2O by CO2) is significantly less than the dried coals. The gas-induced strain (S) and adsorption amount (M) were measured as a function of time following step changes in CO2, CH4, and N2 pressure from vacuum to 1.8 MPa. An empirical diffusion equation was applied to the kinetic data to obtain the exponent (n) for time dependence for each experiment. The data for all coals were pooled and the exponent (n) evaluated using an ANOVA statistical analysis method. Values for (n) near 0.5 were found to be independent on the coal, the gas or type of measurement (e.g., parallel strain, perpendicular strain, and gas uptake). These data support the use of a Fickian diffusion model framework for kinetic analysis. The kinetic constant k was determined using a unipore diffusion model for each experiment and the data were pooled for ANOVA analysis. For dry coal, statistically significant differences for k were found for the gases (CO2 > N2 > CH4) and coals (Pocahontas >Blind Canyon > Pittsburgh #8) but not for the method of the kinetic measurement (e.g., strain or gas uptake). For Blind Canyon and Pittsburgh #8 coal, the rate of CO2 adsorption and gas-induced strain for dry coal was significantly greater than that of the corresponding native coal. For Pocahontas coal the rates of CO2 adsorption and gas-induced strain for dry and native coal were indistinguishable and may be related to its low native moisture and minimal amount of created porosity upon drying.

SEARCHES FOR METAL-POOR STARS FROM THE HAMBURG/ESO SURVEY USING THE CH G BAND  

SciTech Connect

We describe a new method to search for metal-poor candidates from the Hamburg/ESO objective-prism survey (HES) based on identifying stars with apparently strong CH G-band strengths for their colors. The hypothesis we exploit is that large overabundances of carbon are common among metal-poor stars, as has been found by numerous studies over the past two decades. The selection was made by considering two line indices in the 4300 A region, applied directly to the low-resolution prism spectra. This work also extends a previously published method by adding bright sources to the sample. The spectra of these stars suffer from saturation effects, compromising the index calculations and leading to an undersampling of the brighter candidates. A simple numerical procedure, based on available photometry, was developed to correct the line indices and overcome this limitation. Visual inspection and classification of the spectra from the HES plates yielded a list of 5288 new metal-poor (and by selection, carbon-rich) candidates, which are presently being used as targets for medium-resolution spectroscopic follow-up. Estimates of the stellar atmospheric parameters, as well as carbon abundances, are now available for 117 of the first candidates, based on follow-up medium-resolution spectra obtained with the SOAR 4.1 m and Gemini 8 m telescopes. We demonstrate that our new method improves the metal-poor star fractions found by our pilot study by up to a factor of three in the same magnitude range, as compared with our pilot study based on only one CH G-band index. Our selection scheme obtained roughly a 40% success rate for identification of stars with [Fe/H] <-1.0; the primary contaminant is late-type stars with near-solar abundances and, often, emission line cores that filled in the Ca II K line on the prism spectrum. Because the selection is based on carbon, we greatly increase the numbers of known carbon-enhanced metal-poor stars from the HES with intermediate metallicities -2.0 < [Fe/H] <-1.0, which previous survey efforts undersampled. There are eight newly discovered stars with [Fe/H] <-3.0 in our sample, including two with [Fe/H] <-3.5.

Globally, terrestrial ecosystems have absorbed about 30% of anthropogenic greenhouse gas emissions over the period 2000-2007 and inter-hemispheric gradients indicate that a significant fraction of terrestrial carbon sequestration must be north of the Equator. We present a compilation of the CO{sub 2}, CO, CH{sub 4} and N{sub 2}O balances of Europe following a dual constraint approach in which (1) a land-based balance derived mainly from ecosystem carbon inventories and (2) a land-based balance derived from flux measurements are compared to (3) the atmospheric data-based balance derived from inversions constrained by measurements of atmospheric GHG (greenhouse gas) concentrations. Good agreement between the GHG balances based on fluxes (1294 {+-} 545 Tg C in CO{sub 2}-eq yr{sup -1}), inventories (1299 {+-} 200 Tg C in CO{sub 2}-eq yr{sup -1}) and inversions (1210 {+-} 405 Tg C in CO{sub 2}-eq yr{sup -1}) increases our confidence that the processes underlying the European GHG budget are well understood and reasonably sampled. However, the uncertainty remains large and largely lacks formal estimates. Given that European net land to atmosphere exchanges are determined by a few dominant fluxes, the uncertainty of these key components needs to be formally estimated before efforts could be made to reduce the overall uncertainty. The net land-to-atmosphere flux is a net source for CO{sub 2}, CO, CH{sub 4} and N{sub 2}O, because the anthropogenic emissions by far exceed the biogenic sink strength. The dual-constraint approach confirmed that the European biogenic sink removes as much as 205 {+-} 72 Tg C yr{sup -1} from fossil fuel burning from the atmosphere. However, This C is being sequestered in both terrestrial and inland aquatic ecosystems. If the C-cost for ecosystem management is taken into account, the net uptake of ecosystems is estimated to decrease by 45% but still indicates substantial C-sequestration. However, when the balance is extended from CO{sub 2} towards the main GHGs, C-uptake by terrestrial and aquatic ecosystems is offset by emissions of non-CO{sub 2} GHGs. As such, the European ecosystems are unlikely to contribute to mitigating the effects of climate change.

CH2M Hill Hanford Group, Inc. Standards and Requirements Identification Document (SRID) Requirements Management System and Requirements Specification  

SciTech Connect

The current Tank Farm Contractor (TFC) for the U. S. Department of Energy, Office of River Protection (ORP), River Protection Project (RPP), CH2M Hill Hanford Group, Inc. (CHG), will use a computer based requirements management system. The system will serve as a tool to assist in identifying, capturing, and maintaining the Standards/Requirements Identification Document (S/RID) requirements and links to implementing procedures and other documents. By managing requirements as one integrated set, CHG will be able to carry out its mission more efficiently and effectively. CHG has chosen the Dynamic Object Oriented Requirements System (DOORS{trademark}) as the preferred computer based requirements management system. Accordingly, the S/RID program will use DOORS{trademark}. DOORS{trademark} will replace the Environmental Requirements Management Interface (ERMI) system as the tool for S/RID data management. The DOORS{trademark} S/RID test project currently resides on the DOORSTM test server. The S/RID project will be migrated to the DOORS{trademark} production server. After the migration the S/RID project will be considered a production project and will no longer reside on the test server.

THE DETECTION OF INTERSTELLAR ETHANIMINE (CH{sub 3}CHNH) FROM OBSERVATIONS TAKEN DURING THE GBT PRIMOS SURVEY  

SciTech Connect

We have performed reaction product screening measurements using broadband rotational spectroscopy to identify rotational transition matches between laboratory spectra and the Green Bank Telescope PRIMOS radio astronomy survey spectra in Sagittarius B2 North (Sgr B2(N)). The broadband rotational spectrum of molecules created in an electrical discharge of CH{sub 3}CN and H{sub 2}S contained several frequency matches to unidentified features in the PRIMOS survey that did not have molecular assignments based on standard radio astronomy spectral catalogs. Several of these transitions are assigned to the E- and Z-isomers of ethanimine. Global fits of the rotational spectra of these isomers in the range of 8-130 GHz have been performed for both isomers using previously published mm-wave spectroscopy measurements and the microwave measurements of the current study. Possible interstellar chemistry formation routes for E-ethanimine and Z-ethanimine are discussed. The detection of ethanimine is significant because of its possible role in the formation of alanine-one of the twenty amino acids in the genetic code.

Thermogravimetric Analysis of Modified Hematite by Methane (CH{sub 4}) for Chemical-Looping Combustion: A Global Kinetics Mechanism  

SciTech Connect

Iron oxide (Fe{sub 2}O{sub 3}) or in its natural form (hematite) is a potential material to capture CO{sub 2} through the chemical-looping combustion (CLC) process. It is known that magnesium (Mg) is an effective methyl cleaving catalyst and as such it has been combined with hematite to assess any possible enhancement to the kinetic rate for the reduction of Fe{sub 2}O{sub 3} with methane. Therefore, in order to evaluate its effectiveness as a hematite additive, the behaviors of Mg-modified hematite samples (hematite –5% Mg(OH){sub 2}) have been analyzed with regard to assessing any enhancement to the kinetic rate process. The Mg-modified hematite was prepared by hydrothermal synthesis. The reactivity experiments were conducted in a thermogravimetric analyzer (TGA) using continuous stream of CH{sub 4} (5, 10, and 20%) at temperatures ranging from 700 to 825 {degrees}C over ten reduction cycles. The mass spectroscopy analysis of product gas indicated the presence of CO{sub 2}, H{sub 2}O, H{sub 2} and CO in the gaseous product. The kinetic data at reduction step obtained by isothermal experiments could be well fitted by two parallel rate equations. The modified hematite samples showed higher reactivity as compared to unmodified hematite samples during reduction at all investigated temperatures.

Mechanistic and kinetic study on the SN2 and E2 reactions of Cl? with \\{CH3OBr\\}  

Science Journals Connector (OSTI)

Abstract Dual-level direct dynamics method is employed to study the kinetics of the multiple-channel reaction CH3OBr + Cl? for the first time. Geometries have been optimized at the MP2 level with the 6-311+G(d,p) basis set. The minimum energy path is calculated at the same level and further refined at the QCISD(T)/6-311++G(3df,2p) level. The rate constants are obtained by using the canonical variational transition state theory incorporating small-curvature tunneling correction in the temperature range of 200–3000 K. The results show that anti-E2 elimination reaction channel is the dominant channel over the whole temperature range and the corresponding rate constants present negative temperature dependence in the low temperature range, while positive temperature dependence in the high temperature range. The three-parameter Arrhenius expression k = 2.61 × 10?18 T2.29 exp(1395.19/T) for the overall reaction is also given.

THE c2d SPITZER SPECTROSCOPIC SURVEY OF ICES AROUND LOW-MASS YOUNG STELLAR OBJECTS. IV. NH{sub 3} AND CH{sub 3}OH  

SciTech Connect

NH{sub 3} and CH{sub 3}OH are key molecules in astrochemical networks leading to the formation of more complex N- and O-bearing molecules, such as CH{sub 3}CN and CH{sub 3}OCH{sub 3}. Despite a number of recent studies, little is known about their abundances in the solid state. This is particularly the case for low-mass protostars, for which only the launch of the Spitzer Space Telescope has permitted high-sensitivity observations of the ices around these objects. In this work, we investigate the {approx}8-10 {mu}m region in the Spitzer IRS (InfraRed Spectrograph) spectra of 41 low-mass young stellar objects (YSOs). These data are part of a survey of interstellar ices in a sample of low-mass YSOs studied in earlier papers in this series. We used both an empirical and a local continuum method to correct for the contribution from the 10 {mu}m silicate absorption in the recorded spectra. In addition, we conducted a systematic laboratory study of NH{sub 3}- and CH{sub 3}OH-containing ices to help interpret the astronomical spectra. We clearly detect a feature at {approx}9 {mu}m in 24 low-mass YSOs. Within the uncertainty in continuum determination, we identify this feature with the NH{sub 3} {nu}{sub 2} umbrella mode and derive abundances with respect to water between {approx}2% and 15%. Simultaneously, we also revisited the case of CH{sub 3}OH ice by studying the {nu}{sub 4} C-O stretch mode of this molecule at {approx}9.7 {mu}m in 16 objects, yielding abundances consistent with those derived by Boogert et al. based on a simultaneous 9.75 and 3.53 {mu}m data analysis. Our study indicates that NH{sub 3} is present primarily in H{sub 2}O-rich ices, but that in some cases, such ices are insufficient to explain the observed narrow FWHM. The laboratory data point to CH{sub 3}OH being in an almost pure methanol ice, or mixed mainly with CO or CO{sub 2}, consistent with its formation through hydrogenation on grains. Finally, we use our derived NH{sub 3} abundances in combination with previously published abundances of other solid N-bearing species to find that up to 10%-20% of nitrogen is locked up in known ices.

Direct measurements of methoxy removal rate constants for collisions with CH/sub 4/, Ar, N/sub 2/, Xe, and CF/sub 4/ in the temperature range 673--973K  

SciTech Connect

Removal rate constants for CH/sub 3/O by CH/sub 4/, Ar, N/sub 2/, Xe, and CF/sub 4/ were measured over a 400K temperature range using a laser photolysis/laser-induced fluorescence technique. Rapid methoxy removal rates are observed for the non-reactive collision partners (Ar, N/sub 2/, Xe, and CF/sub 4/) at elevated temperatures showing that the dissociation and isomerization channels for CH/sub 3/O are indeed important. The total removal rate constant (reaction /plus/ dissociation and/or isomerization) for CH/sub 4/ exhibits a linear dependence on temperature and has a removal rate constant, k/sub r/ /equals/ (1.2 +- 0.6) /times/ 10/sup /minus/8/exp((/minus/101070 +- 350)/T)cm/sup 3/molecule/sup /minus/1/s/sup /minus/1/. Assuming that the removal rate constant due to dissociation and/or isomerization are similar for CH/sub 4/ and CF/sub 4/, the reaction rate constant for CH/sub 3/O /plus/ CH/sub 4/ is equal to (1.7 +- 1.0) /times/ 10/sup /minus/10/exp((/minus/7480 +- 1100)/T)cm/sup 3/molecule/sup /minus/1/s/sup /minus/1/. 7 refs., 4 figs.

Dark State Illuminated: Infrared Spectrum and Inverted Torsional Structure of the ?11 Out-of-Plane CH3-Rocking Mode of Methanol  

Science Journals Connector (OSTI)

The ?11 out-of-plane CH3-rocking band of methanol, one of the last fundamentals remaining en route to full vibrational description of this prototype internal rotor, has been identified in the Fourier transform spectrum of CH3OH in the 1150 cm-1 region. The ?11 torsional energy pattern is found to be inverted, the first such discovery for a bending state and an important pointer to potential generality of this phenomenon for the whole class of threefold internal rotor molecules. Level-crossing resonances giving transfer channels for intramolecular vibrational energy redistribution (IVR) have been found, and new insights are reported for far-infrared laser emission involving ?11 levels.

Measuring and modeling the competitive adsorption of CO{sub 2}, CH{sub 4}, and N{sub 2} on a dry coal  

SciTech Connect

Data on the adsorption behavior of CO{sub 2}, CH{sub 4}, and N{sub 2} on coal are needed to develop enhanced coalbed methane (ECBM) recovery processes, a technology where the recovery of CH{sub 4} is enhanced by injection of a gas stream consisting of either pure CO{sub 2}, pure N{sub 2}, or a mixture of both. The pure, binary, and ternary adsorption of these gases on a dry coal from the Sulcis Coal Province in Italy has been measured at pressures up to 180 bar and temperatures of 45 and 70{sup o}C for the pure gases and of 45{sup o}C for the mixtures. The experiments were performed in a system consisting of a magnetic suspension balance using a gravimetric-chromatographic technique. The excess adsorption isotherms are successfully described using a lattice density functional theory model based on the Ono-Kondo equations exploiting information about the structure of the coal, the adsorbed gases, and the interaction between them. The results clearly show preferential adsorption of CO{sub 2} over CH{sub 4} and N{sub 2}, which therefore indicate that ECBM may be a viable option for the permanent storage of CO{sub 2}.

Hydrothermal synthesis and structure of an open framework Co0.7Zn1.3(PO4)2(NH3–CH2CH2NH3) and Co6.2(OH)4(PO4)4Zn1.80, a new adamite type phase  

Science Journals Connector (OSTI)

The hydrothermal reaction of cobalt(II)oxalate di-hydrate, zinc oxide, and triethyl-orthophosphate, using 1,2-diaminoethane as structure directing template in water, produced two major crystal phases in almost equal amount: the purple crystals of [NH3–CH2CH2NH3][Co0.7Zn1.3(PO4)2] (1) and the red burgundy crystals of Co6.2(OH)4(PO4)4Zn1.80 (2), a new adamite type phase. The structure of [NH3–CH2CH2NH3] [Co0.7Zn1.3(PO4)2] (1) exhibits a 3D open framework built from PO4 and (Co/Zn)O4 tetrahedra, and (Co/Zn)O5 trigonal bipyramids, forming two major channels, an 8-membered ring channel and a 16-membered ring channel, that host the ethanediammonium ions. The Co6.2(OH)4(PO4)4Zn1.80 (2) is isomorphous with adamite-type M2(OH)XO4 structure, with a condensed vertex and edge sharing network of (Co/Zn)O5, and distorted CoO6, and PO4 subunits. The cobalt preference for higher coordination numbers is displayed in this structure, where the octahedral sites are wholly occupied by cobalt. Thermal analysis confirmed that these compounds display high thermal stability.

Even after addition of possible recycle components methane and CHClF{sub 2}, only minor deactivation was observed during 1600 hours of total operation. The catalyst performance and stability strongly depend on the hydrogen to CCl{sub 2}F{sub 2} feed ratio. A ratio of 6 leads to higher conversion, higher selectivity to CH{sub 2}F{sub 2} and higher stability. At low H{sub 2} to CCl{sub 2}F{sub 2} ratios the mechanism of deactivation is presumably coke deposition. However, the ratio cannot be raised too high because then sintering of the palladium particles causes deactivation. Addition of methane to the feed leads to additional deactivation, and, therefore, methane is only allowed in a recycle stream when high hydrogen to CCl{sub 2}F{sub 2} feed ratios are applied. Addition of CHClF{sub 2} to the feed does not lead to a higher CH{sub 2}F{sub 2} yield. The reaction pathway to CHClF{sub 2} and CH{sub 2}F{sub 2} is different from the route to methane. The selectivity to methane depends on the adsorption mode Of CCl{sub 2}F{sub 2} and is independent of both the CCl{sub 2}F{sub 2} and the hydrogen concentration. The ratio between CHClF{sub 2} and CH{sub 2}F{sub 2} is mainly determined by the CCl{sub 2}F{sub 2} concentration. A CFC-destruction process, which can destruct about 90% of the CFCs in use, based on this catalyst is both technically and economically feasible. The main features of this process are a liquid cooled, multi-tube fixed bed reactor, excess hydrogen, 100% CCl{sub 2}F{sub 2} conversion and a hydrogen recycle, in which methane is allowed.

Strategic use of the underground in an energy mix plan: Synergies among CO2, CH4 geological storage and geothermal energy. Latium Region case study (Central Italy)  

Science Journals Connector (OSTI)

Abstract In recent decades, the worldwide demand for energy has been increasing, with an associated rise in CO2 emissions being observed. In such conditions, the development of “low carbon energy technologies” and strategic energy-mix plans is necessary, and an evaluation of the underground energy potential may be a useful step in developing these plans. This evaluation involves the synergic development of such technologies as: coal combustion in combination with CO2 geological storage (CCS), natural gas geological storage (CH4-GS) and geothermal energy (GE), especially in densely populated countries, such as Italy. Currently, 13.7% of Italian energy demand is met by foreign providers. Most of the Italian regions have energy deficits, and the Latium Region (in Central Italy) represents one of those in the worst conditions. This work proposes a methodology to develop energy-mix scenarios, starting in Latium, to identify areas that are potentially suitable for CCS, CH4-GS and GE. Six geothermal systems and one CO2/CH4 storage potential area were identified. Three main scenarios are proposed: (A) a combination of CH4-GS with methane as cushion gas and GE; (B) a combination of CH4-GS with CO2 as cushion gas and GE; (C) a combination of CCS and GE. Scenario A results in a reduction of the regional energy deficit that ranges from 21.8% to 45.6%. In Scenario B, the regional energy deficit reduction ranges from 30.8% to 80.7% and the CO2 emissions reduction ranges from 1.4% to 5.6%, supposing an injection of 20 years. Scenario C shows a decrease in the regional energy deficit that ranges from 15.9% to 22.1%, while the CO2 emissions reduction ranges from 7.1% to 31.3%, over the same time period. The proposed scenarios may be useful not only for the scientific community but also for policymakers as they identify the most reliable energetic strategies. Thus, this case study could be extended to the entire Italian territory with the ultimate goal of reaching energy autonomy in each region.

Simulation studies of the Cl{sup -}+ CH{sub 3}I S{sub N}2 nucleophilic substitution reaction: Comparison with ion imaging experiments  

SciTech Connect

In the previous work of Mikosch et al.[Science 319, 183 (2008)], ion imaging experiments were used to study the Cl{sup -}+ CH{sub 3}I {yields} ClCH{sub 3}+ I{sup -} reaction at collision energies E{sub rel} of 0.39, 0.76, 1.07, and 1.9 eV. For the work reported here MP2(fc)/ECP/d direct dynamics simulations were performed to obtain an atomistic understanding of the experiments. There is good agreement with the experimental product energy and scattering angle distributions for the highest three E{sub rel}, and at these energies 80% or more of the reaction is direct, primarily occurring by a rebound mechanism with backward scattering. At 0.76 eV there is a small indirect component, with isotropic scattering, involving formation of the pre- and post-reaction complexes. All of the reaction is direct at 1.07 eV. Increasing E{sub rel} to 1.9 eV opens up a new indirect pathway, the roundabout mechanism. The product energy is primarily partitioned into relative translation for the direct reactions, but to CH{sub 3}Cl internal energy for the indirect reactions. The roundabout mechanism transfers substantial energy to CH{sub 3}Cl rotation. At E{sub rel}= 0.39 eV both the experimental product energy partitioning and scattering are statistical, suggesting the reaction is primarily indirect with formation of the pre- and post-reaction complexes. However, neither MP2 nor BhandH/ECP/d simulations agree with experiment and, instead, give reaction dominated by direct processes as found for the higher collision energies. Decreasing the simulation E{sub rel} to 0.20 eV results in product energy partitioning and scattering which agree with the 0.39 eV experiment. The sharp transition from a dominant direct to indirect reaction as E{sub rel} is lowered from 0.39 to 0.20 eV is striking. The lack of agreement between the simulations and experiment for E{sub rel}= 0.39 eV may result from a distribution of collision energies in the experiment and/or a shortcoming in both the MP2 and BhandH simulations. Increasing the reactant rotational temperature from 75 to 300 K for the 1.9 eV collisions, results in more rotational energy in the CH{sub 3}Cl product and a larger fraction of roundabout trajectories. Even though a ClCH{sub 3}-I{sup -} post-reaction complex is not formed and the mechanistic dynamics are not statistical, the roundabout mechanism gives product energy partitioning in approximate agreement with phase space theory.

Nonadditivity effect in the molecular interaction of H{sub 2}O and CH{sub 4} trimers by the symmetry-adapted perturbation theory  

SciTech Connect

The three-body nonadditivity effect has a significant role for various physically important properties. However, since the nonadditivity effect is much smaller than two-body additivity one, its detection is quite difficult. In recent work, the authors have presented the formulas of nonadditivity contribution to the three-body interaction energy in terms of the symmetry-adapted perturbation theory with the Hartree-Fock approximation in Longuet-Higgins representation of the molecular charge distributions. The authors present the results of numerical calculation for the cyclic planar H{sub 2}O trimer as a polar system and CH{sub 4} trimer as a nonpolar system.

E-Print Network (OSTI)

The Muon Detector of the HERA-B experiment at DESY is a gaseous detector that provides muon identification in a high-rate hadronic environment. We present our studies on the properties of several fast gases, Ar/CF4/CH4 (74:20:6), Ar/CF4/CH4 (67:30:3) and Ar/CF4/CO2 (65:30:5), which have been found to fulfill muon detection requirements. The severe radiation environment of the HERA-B experiment leads to the maximum charge deposit on a wire, within the muon detector, of 200 mC/cm per year. For operation in such an environment, the main criteria for the choice of gas turned out to be stability against aging. An overview of aging results from laboratory setups and experimental detectors for binary and ternary mixtures of Ar, CH4, CF4 and CO2 is presented and the relevance of the various aging results is discussed. Since it is not clear how to extrapolate aging results from small to large areas of irradiation, the lifetime of aluminum proportional chambers was studied under various conditions. In this paper we provide evidence that aging results depend not only upon the total collected charge. It was found that the aging rate for irradiation with $Fe^{55}$ X-rays and 100 MeV $\\alpha$-particles may differ by more than two orders of magnitude.

Mechanism of WO{sub 3} reduction and carburization in CH{sub 4}/H{sub 2} mixtures leading to bulk tungsten carbide powder catalysts  

SciTech Connect

The mechanism of bulk tungsten carbide catalysts synthesis from WO{sub 3} in CH{sub 4}/H{sub 2} mixtures has been studied using temperature programmed reactions associated with CH{sub 4}/D{sub 2} exchange reaction and in situ X-ray diffraction. Various experimental parameters have been studied such as partial pressures of reactants, heating rate, mass of precursor, or flow rate in order to determine the most important steps occurring during the transformation of WO{sub 3} to WC. It is shown that at temperatures below 900--923 K the diffusion within the solid particles is slow with respect to the rate of reduction of the surface, allowing the carburization of the surface in the presence of a core still partially oxidized. At higher temperatures, the diffusion is rapid, leading to a uniform reduction within the solid. In this case, the surface is continuously replenished in oxygen thus inhibiting the activation of methane and allowing the carburization to proceed only when the solid is deeply reduced. An inhibiting effect of hydrogen pressure on the interaction of methane with the surface has also been evidenced, an effect which excludes the possibility of an independent control of the reduction process from that of carburization. Finally the role of space velocity has also been elucidated.

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 zero-field thermal conductivity (?) shows a distinct kink at about 0.9?K, which is related to the long-range antiferromagnetic (AF) transition. With applying magnetic field along the c axis, ?(H) curves also show distinct changes at the phase boundaries between the AF and the high-field disordered states. These results indicate a strong spin-phonon interaction and the magnetic excitations play a role in the b-axis heat transport as phonon scatterers.

An accurate data base for the analyzing power of thick CH2 analyzers for high energy protons has been at the basis of several research efforts in a number of laboratories. Starting in the late eighties such data were collected at SATURNE in Saclay, and with the Synchrophasotron in Dubna, and led to an extensive program of study of polarization phenomena in pd interaction, either backward elastic scattering or breakup [1–6]. At about the same time it became evident that measuring polarization observables in elastic ep was going to be the best approach to determine the form factors of the proton, G Ep and G Mp , as had been predicted by Akhiezer and Rekalo [7].

A detailed study of the carburization of Hastelloy-X and alloy 800H in high-temperature gas-cooled reactor helium was made to determine the cause of the wide variability of data generated in retorts. Data for 1000/sup 0/C and 2500-h exposure show that up to an order of magnitude difference in the carburization levels can be caused by changes in the flow rate of the test gas and/or the position of the corrosion specimen in the gas stream. The results are unambiguously explained by the parameters S(H/sub 2/O) and S(CH/sub 4/), the supply rates of water and methane, respectively.

SciTech Connect

A computer code, FCUP, developed by A. Craft computes currents of recoil protons from a time- and energy-dependent neutron flux striking a CH{sub 2} foil. Three problem areas need to be addressed to extend the code`s usefulness. First, FCUP computes a response that is not time dependent; that is, only the input time bin is broadened to account for the finite time distribution of protons from a single neutron energy; second, the time coordinate of the signal predicted is translated arbitrarily rather than absolutely relative to the time of maximum neutron production in the source; and third, the code does not account for electron pickup by protons at low proton energies in the target and absorber foils. This report describes the changes in calculational method used to overcome these problems.

Composition of saturn's atmosphere at northern temperate latitudes from Voyager iris spectra: NH/sub 3/, PH/sub 3/, C/sub 2/H/sub 2/, C/sub 2/H/sub 6/, CH/sub 3/D, CH/sub 4/, and the saturnian D/H isotopic ratio  

SciTech Connect

The abundances of minor atmospheric constituents at northern Saturnian latitudes have been inferred from infrared emission spectra recorded by Voyager. The NH/sub 3/, PH/sub 3/, C/sub 2/H/sub 2/, and C/sub 2/H/sub 6/ vertical distributions have been determined from spectra selected in a cloud-free region centered approximately at the latitude of the Voyager 2 radio-occultation point (36.5 N). The NH/sub 3/ mixing ratio in the upper troposphere is found to be compatible with the saturated partial pressure. The inferred PH/sub 3//H/sub 2/ ratio of 1.4 +- 0.8 x 10/sup -6/ is higher than the value derived from the solar P/H ratio, and the PH/sub 3/ vertical profile may extend somewhat into the stratosphere, up to a few millibars. The stratospheric C/sub 2/H/sub 2//H/sub 2/ and C/sub 2/H/sub 6//H/sub 2/ ratios are, respectively, 2.1 +- 1.4 x 10/sup -7/ and 3.0 x 1.1 x 10/sup -6/; the latter decreases sharply below the 20-50 mbar level. A larger selection of spectra yields CH/sub 3/D/H/sub 2/ = 3.9 +- 2.5 x 10/sup -7/ and CH/sub 4//H/sub 2/ = 4.5/sup +2.4//sub -1.9/ x 10/sup -3/. This result implies an enrichment of Saturn's upper atmosphere is carbon by at least a factor of 3 over the solar abundance. The D/H value resulting from our CH/sub 3/D/CH/sub 4/ ratio is 1.6/sup +1.3//sub -1.2/ x 10/sup -5/, significantly lower than previous determinations obtained from HD lines; it is also less than half of the IRIS-inferred Jovian value. Finally, the interpretation of two NH/sub 3/ lines in the 5 ..mu..m window suggests a NH/sub 3/H/sub 2/ ratio at the 2 bar level below the solar value.

Rate constant measurements suggest an attractive potential for the reaction of CH(a {sup 4}{sigma}{sup -}) with CO, and a vanishingly small energy barrier is predicted here in the CH(a {sup 4}{sigma}{sup -}) + CO reaction channel. The {sup 4}A{open_quotes} state of HCCO is predicted to be bound by about 30 kcal/mol with respect to separated CH(a {sup 4}{sigma}{sup -}) + CO. The authors propose that a spin-forbidden electronic deactivation of CH(a {sup 4}{sigma}{sup -}) might occur through through an intersystem crossing involving the {sup 4}A{open_quotes} state of HCCO. The energetics and the geometries of the reactants and products on both quartet and doublet energy surfaces are presented. The relationship between this research and experimental combustion chemistry has been explored.

Direct ab initio molecular dynamics study on a microsolvated S{sub N}2 reaction of OH{sup -}(H{sub 2}O) with CH{sub 3}Cl  

SciTech Connect

Reaction dynamics for a microsolvated S{sub N}2 reaction OH{sup -}(H{sub 2}O)+CH{sub 3}Cl have been investigated by means of the direct ab initio molecular dynamics method. The relative center-of-mass collision energies were chosen as 10, 15, and 25 kcal/mol. Three reaction channels were found as products. These are (1) a channel leading to complete dissociation (the products are CH{sub 3}OH+Cl{sup -}+H{sub 2}O: denoted by channel I), (2) a solvation channel (the products are Cl{sup -}(H{sub 2}O)+CH{sub 3}OH: channel II), and (3) a complex formation channel (the products are CH{sub 3}OH{center_dot}{center_dot}{center_dot}H{sub 2}O+Cl{sup -}: channel III). The branching ratios for the three channels were drastically changed as a function of center-of-mass collision energy. The ratio of complete dissociation channel (channel I) increased with increasing collision energy, whereas that of channel III decreased. The solvation channel (channel II) was minor at all collision energies. The selectivity of the reaction channels and the mechanism are discussed on the basis of the theoretical results.

Absolute rate constants for the gas-phase reaction is of the NO/sub 3/ radical with CH/sub 3/SCH/sub 3/, NO/sub 2/, CO, and a series of alkanes at 298 +/- 2 K  

SciTech Connect

A flash photolysis-visible absorption apparatus has been constructed and employed in a study of the kinetics of the gas-phase reactions of the NO/sub 3/ radical with CH/sub 3/SCH/sub 3/, NO/sub 2/, CO, CH/sub 4/, C/sub 2/H/sub 6/, and n-C/sub 4/H/sub 10/. The measured absolute rate constants at 298 +/- 2 K are as follows (in units of 10/sup -13/ cm/sup 3/ molecule/sup -1/ s/sup -1/): CH/sub 3/SCH/sub 3/, 7.5 +/- 0.5 independent of pressure over the range 50-400 Torr; NO/sub 2/, 5.6 +/- 0.4 and 8.0 +/- 1.1 at 120 and 400 Torr total pressure of helium, respectively; CO, less than or equal to 0.00003; CH/sub 4/, less than or equal to 0.0002; C/sub 2/H/sub 6/, less than or equal to 0.00004; n-C/sub 4/H/sub 10/, less than or equal to 0.0002. The error limits represent two standard deviations. (Systematic errors could contribute an additional approx. 10% range.) These results are discussed with respect to the previous literature data and the atmospheric lifetimes of these compounds. The rate constant for the reaction of NO/sub 3/ radicals with CH/sub 3/SCH/sub 3/ measured in the present work is consistent with both another recent absolute determination and previous relative rate measurements, confirming the relative rate technique previously used to determine NO/sub 3/ radical reaction rate constants.
