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

SciTech Connect (OSTI)

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.

Reactions of the CN Radical with Benzene and Toluene: Product Detection and Low-Temperature Kinetics  

SciTech Connect (OSTI)

Low temperature rate coefficients are measured for the CN + benzene and CN + toluene reactions using the pulsed Laval nozzle expansion technique coupled with laser-induced fluorescence detection. The CN + benzene reaction rate coefficient at 105, 165 and 295 K is found to be relatively constant over this temperature range, 3.9 - 4.9 x 10-10 cm3 molecule-1 s-1. These rapid kinetics, along with the observed negligible temperature dependence, are consistent with a barrierless reaction entrance channel and reaction efficiencies approaching unity. The CN + toluene reaction is measured to have a slower rate coefficient of 1.3 x 10-10 cm3 molecule-1 s-1 at 105 K. At room temperature, non-exponential decay profiles are observed for this reaction that may suggest significant back-dissociation of intermediate complexes. In separate experiments, the products of these reactions are probed at room temperature using synchrotron VUV photoionization mass spectrometry. For CN + benzene, cyanobenzene (C6H5CN) is the only product recorded with no detectable evidence for a C6H5 + HCN product channel. In the case of CN + toluene, cyanotoluene (NCC6H4CH3) constitutes the only detected product. It is not possible to differentiate among the ortho, meta and para isomers of cyanotoluene because of their similar ionization energies and the ~;; 40 meV photon energy resolution of the experiment. There is no significant detection of benzyl radicals (C6H5CH2) that would suggest a H-abstraction or a HCN elimination channel is prominent at these conditions. As both reactions are measured to be rapid at 105 K, appearing to have barrierless entrance channels, it follows that they will proceed efficiently at the temperatures of Saturn?s moon Titan (~;;100 K) and are also likely to proceed at the temperature of interstellar clouds (10-20 K).

Infrared spectra of ClCN{sup +}, ClNC{sup +}, and BrCN{sup +} trapped in solid neon  

SciTech Connect (OSTI)

When a mixture of ClCN or BrCN with a large excess of neon is codeposited at 4.3 K with a beam of neon atoms that have been excited in a microwave discharge, the infrared spectrum of the resulting solid includes prominent absorptions of the uncharged isocyanide, ClNC or BrNC, and of the corresponding cation, ClCN{sup +} or BrCN{sup +}. The NC-stretching fundamentals of the isocyanides trapped in solid neon lie close to the positions for their previously reported argon-matrix counterparts. The CN-stretching absorptions of ClCN{sup +} and BrCN{sup +} and the CCl-stretching absorption of ClCN{sup +} appear very close to the gas-phase band centers. Absorptions of two overtones and one combination band of ClCN{sup +} are identified. Reversible photoisomerization of ClCN{sup +} to ClNC{sup +} occurs. The two stretching vibrational fundamentals and several infrared and near infrared absorptions associated with electronic transitions of ClNC{sup +} are observed. Minor infrared peaks are attributed to the vibrational fundamental absorptions of the CX and CX{sup +} species (X=Cl,Br)

The unimolecular reaction of isolated CF3CN: Energy disposal into CN product degrees of freedom  

Science Journals Connector (OSTI)

Measurements of nascent CN rovibronic state distributions following the unimolecular reaction CF3CN?CF3+CN are reported. Excitation under collision?free conditions is provided by IR multiple photon excitation using the focused output from a CO2?TEA laser and therefore reaction occurs from a range of energiesE ? centered at some value which is determined by the laser intensity. Nascent reaction products are detected by laser induced fluorescence(LIF) and by exciting the ?v = 0 ?1 and ?2 sequences of the B? 2?+?X? 2?+ system rotational distributions can be determined for v ? = 0 1 and 2 with no interference. Rotational excitation in v ? = 0–2 is the same for each v ? and can be described by a Boltzmann distribution with T R = 1200±100 K. Product translational energies are estimated by monitoring LIF intensities as a function of the delay between the onsets of the CO2 and dye laser pulses. Translational energies do not change over the range v ? = 0–4 and can be ascribed a temperature of 850±150 K. CN vibrational excitation is determined by simulating the LIF spectra and can be described by T V = 2400±150 K based on v ? = 0–3 with v ? = 4 barely detectable. These results can be explained qualitatively using a statistically based model in which the CN vibration acts as a thermometer of parent excitation and where parent nuclear motions including vibrations as well as motions n o t influenced by potential energy are in equilibrium at the transition state. The constancy of rotational and translational excitations with respect to v ? are seen to derive from the range of E ? from which dissociation occurs.

Silo & HDF5 I/O Scaling Improvements on BG/P Systems  

SciTech Connect (OSTI)

Silo and HDF5 are I/O libraries used by many codes important to the LLNL's Weapons and Complex Integration (WCI) mission. In the past year, modest adjustments and tuning of Silo, HDF5 and the I/O configuration of the BG/P platform, Dawn, were undertaken. A key goal of this work was to improve I/O performance without requiring any changes in the application codes themselves. In particular, the application codes have been allowed to continue to use a simplified yet highly flexible I/O paradigm known as 'Poor Man's Parallel I/O', where scalability is achieved through concurrent, serial I/O to multiple files. The results demonstrate substantial performance gains (better than 50x in many cases) at large scale (greater than 64,000 MPI tasks). They describe key enhancements made to Silo, HDF5 and the I/O configuration of our BG/P platform and present very favorable results from scalability studies over a wide range of operating scenarios.

Performance Analysis of and Tool Support for Transactional Memory on BG/Q  

SciTech Connect (OSTI)

Martin Schindewolf worked during his internship at the Lawrence Livermore National Laboratory (LLNL) under the guidance of Martin Schulz at the Computer Science Group of the Center for Applied Scientific Computing. We studied the performance of the TM subsystem of BG/Q as well as researched the possibilities for tool support for TM. To study the performance, we run CLOMP-TM. CLOMP-TM is a benchmark designed for the purpose to quantify the overhead of OpenMP and compare different synchronization primitives. To advance CLOMP-TM, we added Message Passing Interface (MPI) routines for a hybrid parallelization. This enables to run multiple MPI tasks, each running OpenMP, on one node. With these enhancements, a beneficial MPI task to OpenMP thread ratio is determined. Further, the synchronization primitives are ranked as a function of the application characteristics. To demonstrate the usefulness of these results, we investigate a real Monte Carlo simulation called Monte Carlo Benchmark (MCB). Applying the lessons learned yields the best task to thread ratio. Further, we were able to tune the synchronization by transactifying the MCB. Further, we develop tools that capture the performance of the TM run time system and present it to the application's developer. The performance of the TM run time system relies on the built-in statistics. These tools use the Blue Gene Performance Monitoring (BGPM) interface to correlate the statistics from the TM run time system with performance counter values. This combination provides detailed insights in the run time behavior of the application and enables to track down the cause of degraded performance. Further, one tool has been implemented that separates the performance counters in three categories: Successful Speculation, Unsuccessful Speculation and No Speculation. All of the tools are crafted around IBM's xlc compiler for C and C++ and have been run and tested on a Q32 early access system.

Operator-Schmidt decomposition of the quantum Fourier transform on C^N1 tensor C^N2  

E-Print Network [OSTI]

Operator-Schmidt decompositions of the quantum Fourier transform on C^N1 tensor C^N2 are computed for all N1, N2 > 1. The decomposition is shown to be completely degenerate when N1 is a factor of N2 and when N1>N2. The first known special case, N1=N2=2^n, was computed by Nielsen in his study of the communication cost of computing the quantum Fourier transform of a collection of qubits equally distributed between two parties. [M. A. Nielsen, PhD Thesis, University of New Mexico (1998), Chapter 6, arXiv:quant-ph/0011036.] More generally, the special case N1=2^n1<2^n2=N2 was computed by Nielsen et. al. in their study of strength measures of quantum operations. [M.A. Nielsen et. al, (accepted for publication in Phys Rev A); arXiv:quant-ph/0208077.] Given the Schmidt decompositions presented here, it follows that in all cases the communication cost of exact computation of the quantum Fourier transform is maximal.

The luminosity function of galaxies to $M_{BgVriz} \\sim -14$ in $z \\sim 0.3$ clusters  

E-Print Network [OSTI]

We present deep composite luminosity functions in $B$, $g$, $V$, $r$, $i$ and $z$ for six clusters at $0.14 sim -14 + 5\\log h$ mag. and are well fitted by a single Schechter function with $M^*_{BgVriz}=-19.8, -20.9 -21.9, -22.0, -21.7, -22.3$ mag. and $\\alpha \\sim -1.3$ (in all bands). The observations suggest that the galaxy luminosity function is dominated by objects on the red sequence to at least 6 mags. below the $L^*$ point. Comparison with local data shows that the red sequence is well established at least at $z \\sim 0.3$ down to $\\sim 1/600^{th}$ of the luminosity of the Milky Way and that galaxies down to the regime of dwarf spheroidals have been completely assembled in clusters at this redshift. We do not detect a steepening of the luminosity function at $M > -16$ as is observed locally. If the faint end upturn is real, the steepening of the luminosity function must be due to a newly infalling population of faint dwarf galaxies.

UMCP-BG and E collaboration in nuclear power engineering in the framework of DOE-Utility Nuclear Power Engineering Education Matching Grant Program  

SciTech Connect (OSTI)

The DOE-Utility Nuclear Power Engineering Education Matching Grant Program has been established to support the education of students in Nuclear Engineering Programs to maintain a knowledgeable workforce in the United States in order to keep nuclear power as a viable component in a mix of energy sources for the country. The involvement of the utility industry ensures that this grant program satisfies the needs and requirements of local nuclear energy producers and at the same time establishes a strong linkage between education and day-to-day nuclear power generation. As of 1997, seventeen pairs of university-utility partners existed. UMCP was never a member of that group of universities, but applied for the first time with a proposal to Baltimore Gas and Electric Company in January 1999 [1]. This proposal was generously granted by BG&E [2,3] in the form of a gift in the amount of $25,000 from BG&E's Corporate Contribution Program. Upon the arrival of a newly appointed Director of Administration in the Department of Materials and Nuclear Engineering, the BG&E check was deposited into the University's Maryland Foundation Fund. The receipt of the letter and the check enabled UMCP to apply for DOE's matching funds in the same amount by a proposal.

Star formation around the mid-infrared bubble CN 148  

E-Print Network [OSTI]

We present a multi-wavelength study to analyse the star formation process associated with the mid-infrared bubble CN 148 (H II region G10.3-0.1), which harbors an O5V-O6V star. The arc-shaped distribution of molecular CO(2-1) emission, the cold dust emission, and the polycyclic aromatic hydrocarbon features trace a photodissociation region (PDR) around the H II region. We have identified 371 young stellar objects (YSOs) in the selected region and, interestingly, their spatial distribution correlates well with the PDR. 41% of these YSOs are present in 13 clusters, each having visual extinction larger than 16 mag. The clusters at the edges of the bubble (both northeast and southwest) are found to be relatively younger than the clusters located further away from the bubble. We also find that four 6.7 GHz methanol masers, two Extended Green Objects, an ultra-compact H II region, and a massive protostar candidate (as previously reported) are spatially positioned at the edges of the bubble. The existence of an appa...

CN ANOMALIES IN THE HALO SYSTEM AND THE ORIGIN OF GLOBULAR CLUSTERS IN THE MILKY WAY  

SciTech Connect (OSTI)

We explore the kinematics and orbital properties of a sample of red giants in the halo system of the Milky Way that are thought to have formed in globular clusters based on their anomalously strong UV/blue CN bands. The orbital parameters of the CN-strong halo stars are compared to those of the inner- and outer-halo populations as described by Carollo et al., and to the orbital parameters of globular clusters with well-studied Galactic orbits. The CN-strong field stars and the globular clusters both exhibit kinematics and orbital properties similar to the inner-halo population, indicating that stripped or destroyed globular clusters could be a significant source of inner-halo field stars, and suggesting that both the CN-strong stars and the majority of globular clusters are primarily associated with this population.

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 (OSTI)

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.

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 (OSTI)

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.

DETECTION OF FeCN (X {sup 4}{Delta}{sub i} ) IN IRC+10216: A NEW INTERSTELLAR MOLECULE  

SciTech Connect (OSTI)

A new interstellar molecule, FeCN (X {sup 4}{Delta}{sub i} ), has been detected in the envelope of the carbon-rich asymptotic giant branch star, IRC+10216. This work is the first definitive detection of an iron-bearing molecule in the interstellar medium and is based on newly measured rest frequencies. Eight successive rotational transitions of this linear free radical in the lowest spin ladder, {Omega} = 7/2, were observed at 2 and 3 mm using the Arizona Radio Observatory (ARO) 12 m telescope. Three transitions appear as single, unblended features at the 1-2 mK level and exhibit characteristic IRC+10216 line profiles; one had previously been observed with the IRAM 30 m telescope. Two other transitions are partially blended, but exhibit distinct emission at the FeCN frequencies. The remaining transitions are either completely contaminated, or are too high in energy. Comparison of the ARO and IRAM data suggests a source size for FeCN of {approx}30'' in IRC+10216, indicating an outer shell distribution, as expected for a free radical. The column density derived for FeCN is N{sub tot} = 8.6 x 10{sup 11} cm{sup -2} with a rotational temperature of T{sub rot} = 21 K. The fractional abundance of this molecule is [FeCN]/[H{sub 2}] {approx} 2-7 x 10{sup -10}-comparable to that of MgCN and KCN in IRC+10216. FeCN is likely formed by gas-phase reactions of Fe{sup +} or neutral iron; the latter has a significant gas-phase abundance in the outer shell. The detection of FeCN is further evidence that metal cyanides/isocyanides dominate the chemistry of refractory elements in IRC+10216.

Quantum Critical Transition Amplifies Magnetoelastic Coupling in Mn[N(CN)2]2  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

We report the discovery of a magnetic quantum critical transition in Mn[N(CN)2]2 that drives the system from a canted antiferromagnetic state to the fully polarized state with amplified magnetoelastic coupling as an intrinsic part of the process. The local lattice distortions, revealed through systematic phonon frequency shifts, suggest a combined MnN6 octahedra distortion+counterrotation mechanism that reduces antiferromagnetic interactions and acts to accommodate the field-induced state. These findings deepen our understanding of magnetoelastic coupling near a magnetic quantum critical point and away from the static limit.

Sub-Doppler Stark Spectroscopy in the A?X (1,0) Band of CN

The effect of external electric fields has been measured in hyperfine-resolved sub-Doppler transitions in the A {sup 2}{Pi}-X {sup 2}{Sigma} (1,0) band of the CN radical near 10900 cm{sup -1}. Static electric fields less than 1 kV/cm are sufficient to mix the most closely spaced {Lambda}-dpublets in the A state, leading to Stark spectra with both new and shifted resonances. Simulations of the saturation-dip Stark spectral line profiles allow extraction of the A-state permanent electric dipole moment with a magnitude of 0.06 {+-} 0.02 D.

Infrared Intensity Enhancement of the CN Stretch of HCN by Coadsorbed CO on the Cu(100) Surface  

Science Journals Connector (OSTI)

Reflection absorption infrared spectra reveal a strong enhancement in the intensity of the CN stretch in a mixed ordered overlayer of HCN and CO on the Cu(100) surface. Various combinations of HCN and CO isotopomers show that the intensity enhancement decreases with increasing frequency difference between ?CN and ?CO. The intensity of the 2092 cm-1 band of H12C14N is enhanced by a factor of 155±20 through coupling to the 2077 cm-1 band of 12C16O. A simple two-state coupling model explains the isotopomer dependence of the degree of enhancement.

Concurrent Collections (CnC): A new approach to parallel programming  

ScienceCinema (OSTI)

A common approach in designing parallel languages is to provide some high level handles to manipulate the use of the parallel platform. This exposes some aspects of the target platform, for example, shared vs. distributed memory. It may expose some but not all types of parallelism, for example, data parallelism but not task parallelism. This approach must find a balance between the desire to provide a simple view for the domain expert and provide sufficient power for tuning. This is hard for any given architecture and harder if the language is to apply to a range of architectures. Either simplicity or power is lost. Instead of viewing the language design problem as one of providing the programmer with high level handles, we view the problem as one of designing an interface. On one side of this interface is the programmer (domain expert) who knows the application but needs no knowledge of any aspects of the platform. On the other side of the interface is the performance expert (programmer or program) who demands maximal flexibility for optimizing the mapping to a wide range of target platforms (parallel / serial, shared / distributed, homogeneous / heterogeneous, etc.) but needs no knowledge of the domain. Concurrent Collections (CnC) is based on this separation of concerns. The talk will present CnC and its benefits. About the speaker Kathleen Knobe has focused throughout her career on parallelism especially compiler technology, runtime system design and language design. She worked at Compass (aka Massachusetts Computer Associates) from 1980 to 1991 designing compilers for a wide range of parallel platforms for Thinking Machines, MasPar, Alliant, Numerix, and several government projects. In 1991 she decided to finish her education. After graduating from MIT in 1997, she joined Digital Equipment?s Cambridge Research Lab (CRL). She stayed through the DEC/Compaq/HP mergers and when CRL was acquired and absorbed by Intel. She currently works in the Software and Services Group / Technology Pathfinding and Innovation.

Theoretical study of radiative electron attachment to CN, C2H, and C4H radicals  

E-Print Network [OSTI]

A first-principle theoretical approach to study the process of radiative electron attachment is developed and applied to the negative molecular ions CN$^-$, C$_4$H$^-$, and C$_2$H$^-$. Among these anions, the first two have already been observed in the interstellar space. Cross sections and rate coefficients for formation of these ions by radiative electron attachment to the corresponding neutral radicals are calculated. For completeness of the theoretical approach, two pathways for the process have been considered: (i) A direct pathway, in which the electron in collision with the molecule spontaneously emits a photon and forms a negative ion in one of the lowest vibrational levels, and (ii) an indirect, or two-step pathway, in which the electron is initially captured through non-Born-Oppenheimer coupling into a vibrationally resonant excited state of the anion, which then stabilizes by radiative decay. We develop a general model to describe the second pathway and show that its contribution to the formation o...

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

SciTech Connect (OSTI)

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.

Seasonal variation of CH4 emissions from central California

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.

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.

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

SciTech Connect (OSTI)

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.

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.

Observation of a remarkable temperature effect in the hydrogen bonding structure and dynamics of the CN-(H2O) cluster  

SciTech Connect (OSTI)

The CN-(H2O) cluster represents a model diatomic monohydrate with multiple solvation sites. We report joint experimental and theoretical studies of its structure and dynamics using temperature-controlled photoelectron spectroscopy (PES) and ab-initio electronic structure calculations. The observed PES spectra of CN-(H2O) display a remarkable temperature effect, namely that the T=12 K spectrum shows an unexpectedly large blue shift of 0.25 eV in the electron binding energy relative to the Room Temperature (RT) spectrum. Extensive theoretical analysis of the potential energy function (PEF) of the cluster at the CCSD(T) level of theory reveal the existence of two nearly isoenergetic isomers corresponding to H2O forming a H-bond with either the C or the N atom, respectively. This results in four topologically distinct minima, i.e., CN-(HaOHb), CN-(HbOHa), NC-(HaOHb) and NC-(HbOHa). There are two main pathways connecting these minima: (i) CN- tumbling relative to water and (ii) water rocking relative to CN-. The relative magnitude of the barriers associated with these two motions reverses between low [pathway (i) is preferred] and high [pathway (ii) is preferred] temperatures. As a result, at T=12 K the cluster adopts a structure that is close to the minimum energy CN-(H2O) configuration, while at RT it can effectively access regions of the PEF close to the transition state for pathway (ii), explaining the surprisingly large spectral shift between the 12 K and RT PES spectra. This work was supported by the Division of Chemical Sciences, Geosciences and Biosciences, Office of Basic Energy Sciences, US Department of Energy.

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.

Mechanical Properties, sliding wear and solid particle erosion behaviors of plasma enhanced magnetron sputtering CrSiCN coating Systems  

Science Journals Connector (OSTI)

Abstract CrSiCN coating systems with different concentrations of Cr, Si, C, and N were investigated for their microstructure, mechanical properties (hardness H, elastic modulus E and indentation fracture toughness KIC) and tribological behaviors using SEM, nano-indentation, indentation, pin-on-disk wear test, and sand particle erosion test. The wear behaviors, such as specific wear rate and Archard wear coefficient, showed inverse relationships with H3/E2 ratio, confirming that the resistance to plastic deformation is the essential factor governing sliding wear behavior. High H3/E2 ratios also contributed to increased resistances to erosion at low impingement angles. However, at higher impingement angles (>60°), coatings with lower index of brittleness (B=2.656 µm?1/2), higher critical load (P?=6.670 N) for crack initiation and fracture surface energy (?f=0.123 Jm?2) offered a higher erosion resistance. The indentation fracture toughness (KIC), hardness (H) and elastic modulus (E) are limited to interpret erosion behaviors in a comprehensive approach, suggesting that erosion is a complex process where multiple mechanical properties contribute to erosion performance.

Two-phase nc-TiN/a-(C,CN{sub x}) nanocomposite films: A HRTEM and MC simulation study  

SciTech Connect (OSTI)

The grain growth in two-phase nanocomposite Ti-C{sub x}-N{sub y} thin films grown by reactive close-field unbalanced magnetron sputtering in an Ar-N{sub 2} gas mixture with microstructures comprising of nanocrystalline (nc-) Ti(N,C) phase surrounded by amorphous (a-) (C,CN{sub x}) phase was investigated by a combination of high-resolution transmission electron microscopy (HRTEM) and Monte Carlo (MC) simulations. The HRTEM results revealed that amorphous-free solid solution Ti(C,N) thin films exhibited polycrystallites with different sizes, orientations and irregular shapes. The grain size varied in the range between several nanometers and several decade nanometers. Further increase of C content (up to {approx}19 at.% C) made the amorphous phase wet nanocrystallites, which strongly hindered the growth of nanocrystallites. As a result, more regular Ti(C,N) nanocrystallites with an average size of {approx}5 nm were found to be separated by {approx}0.5-nm amorphous phases. When C content was further increased (up to {approx}48 at.% in this study), thicker amorphous matrices were produced and followed by the formation of smaller sized grains with lognormal distribution. Our MC analysis indicated that with increasing amorphous volume fraction (i.e. increasing C content), the transformation from nc/nc grain boundary (GB)-curvature-driven growth to a/nc GB-curvature-driven growth is directly responsible for the observed grain growth from great inhomogeneity to homogeneity process.

ChIP-seq Identification of Weakly Conserved Heart Enhancers  

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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.

Evaluation of Flood Runoff Reduction Effect of LID (Low Impact Development) based on the Decrease in CN: Case Studies from Gimcheon Pyeonghwa District, Korea  

Science Journals Connector (OSTI)

Abstract LID are spread on a small scale throughout target area, therefore, evaluation of their overall effect on flood reduction is not straightforward. As one solution dealing with this problem, Yoo et al. (2012) proposed a methodology for quantifying the flood runoff reduction effect of storage facilities by curve number (CN). Introduction of various infiltration or storage facilities causes the decrease in CN, which can be calculated using the runoff. The result derived was summarized in a graph showing the decrease in CN as an effect of the runoff reduction. That is, the runoff reduction effect of infiltration or storage facilities was able to be easily estimated using the derived graph. In this study, LID effects of Gimcheon Pyeonghwa district in Korea was quantified using this method. Additionally, the reduction amount of the runoff volume using the method suggested by Yoo et al. (2012) was compared with that estimated by using SWMM 5.0. As a result of this, the effect of LID facilities was shown similarly in both cases using the methodology used in this study and simulated using SWMM 5.0. This result verified that the methodology was valid even though it is straightforward and simple.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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}).

Stereoselective SN2? alkylation reaction sequence of the ?,?-epoxy ?,?-unsaturated ester system via ?,?-chlorohydrin intermediates by the use of a R3Al–CuCN reagent  

Science Journals Connector (OSTI)

A novel stereoselective SN2? alkylation reaction sequence of the ?,?-epoxy ?,?-unsaturated ester system has been developed which involves a regioselective substitution reaction with chloride ions at the ?-position and a subsequent SN2? alkylation reaction of the resulting ?-chloro-?-hydroxy derivatives with a R3Al–CuCN reagent. The new methodology was demonstrated to be applicable to a variety of substrates and to provide various ?-hydroxy-?-alkyl-?,?-unsaturated esters including those bearing a quaternary asymmetric carbon atom at the ?-position in a highly stereoselective manner and high yields.

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.

Capturing inhomogeneous broadening of the -CN stretch vibration in a Langmuir monolayer with high-resolution spectra and ultrafast vibrational dynamics in sum-frequency generation vibrational spectroscopy (SFG-VS)  

SciTech Connect (OSTI)

Even though in principle the frequency-domain and time-domain spectroscopic measurement should generate identical information for a given molecular system, inhomogeneous character of surface vibrations in the sum-frequency generation vibrational spectroscopy (SFG-VS) studies has only been studied with the time-domain SFGVS by mapping the decay of the vibrational polarization using ultrafast lasers, due to the lack of SFG vibrational spectra with high enough spectral resolution and accurate enough line shape. Here with recently developed high-resolution broadband SFG-VS (HR-BB-SFG-VS) we show that the inhomogeneous line shape can be obtained in the frequency-domain, for the anchoring CN stretch of the 4-n-octyl-4'-cyanobiphenyl (8CB) Langmuir monolayer at the air-water interface, and that an excellent agreement with the time-domain SFG free-induction-decay (FID) results can be established. We found that the 8CB CN stretch spectrum consists of a single peak centered at 2234.00 + * 0.01 cm-1 with a total line width of 10.9 + - 0.3 cm-1 at half maximum. The Lorentzian contribution accounts only for 4:7 + -0:4 cm-1 to this width and the Gaussian (inhomogeneous) broadening for as much as 8:1+*0:2 cm-1. Polarization analysis of the -CN spectra showed that the -CN group is tilted 57 + - 2 degrees from the surface normal. The large heterogeneity in the -CN spectrum is tentatively attributed to the -CN group interactions with the interfacial water molecules penetrated/accomodated into the 8CB monolayer, a unique phenomenon for the nCB Langmuir monolayers reported previously.

Superconductivity and fluctuating magnetism in quasi-two-dimensional {kappa}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Br probed with implanted muons.  

SciTech Connect (OSTI)

A muon-spin relaxation ({mu}{sup +}SR) investigation is presented for the molecular superconductor {kappa}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Br. Evidence is found for low-temperature phase separation throughout the bulk of the material, with only a fraction of the sample showing a superconducting signal, even for slow cooling. Rapid cooling reduces the superconducting fraction still further. For the superconducting phase, the in-plane penetration depth is measured to be {lambda}{parallel} = 0.47(1) {micro}m, and evidence is seen for a vortex decoupling transition in applied fields above 40 mT. The magnetic fluctuations in the normal state produce a precipitous drop in relaxation rate above 100 K, and we discuss the possible causes for the unusual relaxation that we observe for T > T{sub c}.

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

SciTech Connect (OSTI)

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.

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

SciTech Connect (OSTI)

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 (OSTI)

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.

Results of x-ray crystallographic studies of the complex HFe/sub 4/(eta/sup 2/-CH)(CO)/sub 12/ are reported. The complex may provide information that relates to intermediates in some metal-surface catalyzed Fischer-Tropsch reactions. The complex was found to contain a butterfly array of four Fe atoms, each with three terminal carbonyl ligands, with the carbidic C atom nestled near the center of the top of the wings of the Fe/sub 4/ array where it forms a strong C-H-Fe interaction. Measurements of the bond distances are given. (BLM)

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 (OSTI)

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}).

In transition metal cluster chemistry, compounds consisting of both a cluster cation and a cluster anion are not very common. The first members of this type of compound of the composition [M{sub 6}X{sub 12}(EtOH){sub 6}][(Mo{sub 6}Cl{sub 8})Cl{sub 4}X{sub 2}]{center{underscore}dot}mEtOH{center{underscore}dot}nEt{sub 2}O (M = Nb, Ta; X = Cl, Br) have been recently prepared.

In fact, these compounds consist of two different heteronuclear cluster units with different charges: [M{sub 6}X{sub 12}]{sup 2+} in the cation and [Mo{sub 6}Cl{sub 8}]{sup 4+} in the anion. The preparation of cation-anion pairs with homonuclear mixed-charge cluster units is also possible. In the present study, the synthesis and crystal structure of the cluster pair [Ta{sub 6}Cl{sub 12}(PrCN){sub 6}][(Ta{sub 6}Cl{sub 12})Cl{sub 6}]{center{underscore}dot}2PrCN is reported. The compound is built of two octahedral homonuclear mixed-charge cluster units: [Ta{sub 6}Cl{sub 12}]{sup 2+} in the [Ta{sub 6}Cl{sub 12}(PrCN){sub 6}]{sup 2+} cluster cation and [Ta{sub 6}Cl{sub 12}]{sup 4+} in the [(Ta{sub 6}Cl{sub 12})Cl{sub 6}]{sup 2{minus}} cluster anion.

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 (OSTI)

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.

Cn2 and wind profiler method to quantify the frozen flow decay using wide-field laser guide stars adaptive optics  

E-Print Network [OSTI]

We use spatio-temporal cross-correlations of slopes from five Shack-Hartmann wavefront sensors to analyse the temporal evolution of the atmospheric turbulence layers at different altitudes. The focus is on the verification of the frozen flow assumption. The data is coming from the Gemini South Multi-Conjugate Adaptive Optics System (GeMS). First, the Cn2 and wind profiling technique is presented. This method provides useful information for the AO system operation such as the number of existing turbulence layers, their associated velocities, altitudes and strengths and also a mechanism to estimate the dome seeing contribution to the total turbulence. Next, by identifying the turbulence layers we show that it is possible to estimate the rate of decay in time of the correlation among turbulence measurements. We reduce on-sky data obtained during 2011, 2012 and 2013 campaigns and the first results suggest that the rate of temporal de-correlation can be expressed in terms of a single parameter that is independent ...

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.

Section 5.2.14 dis- cusses potential impacts to INEEL water resources from accidents or unusual natural phe- nomena such as earth- quakes. Appendix C.9 discusses potential long- term impacts to INEEL water resources from facility closure. Because the Minimum INEEL Processing Alternative would involve shipment of mixed HLW to the Hanford Site for treat- ment, possible impacts to water resources at Hanford were also evalu- ated (see Appendix C.8).

This could require removal of all buildings, vaults, tanks, transfer piping, and contaminated soil. No post- closure monitoring would be required because potential sources of contamination would no longer be present. Unrestricted industrial use of clean-closed facilities and sites will be permissi- ble. Impacts to water resources would not be expected from the disposition of new facilities. For Performance-Based Closure, most above- ground structures would be razed and most below-ground structures (tanks, vaults, and transfer piping) would be decontaminated, stabi-

This Order and its associated Manual and Guidance set forth the authorities, responsibilities, and requirements for the management of DOE's inventory of HLW, transuranic waste, and low-level waste. Specific to HLW, DOE uses the Nuclear Waste Policy Act definition but has jurisdictional authority consistent with existing law to deter- mine if the waste requires permanent isolation as the appropriate disposal mechanism. This authority is based on enabling legislation in the Atomic Energy Act, sections 202(3) and 202(4)

A more detailed description of geology at INEEL can be reviewed in the SNF & INEL EIS, Volume 2, Part A, Section 4.6 (DOE 1995). 4.6.1 GENERAL GEOLOGY INEEL occupies a relatively flat area on the northwestern edge of the Eastern Snake River Plain. Figure 4-4 shows important geological features of the INEEL area. The area consists of a broad plain that has been built up from the eruptions of multi- ple flows of basaltic lava, which is shown on Figure 4-5. The flows at the surface range in age from 1.2 million to 2,100 years. The Plain is bounded on the north and south by the north-to-north-

The radiation dose values for the var- ious alternatives were then multiplied by the dose-to-risk conversion factors, which are based on the 1993 Limitations of Exposure to Ionizing Radiation (NCRP 1993). DOE has adopted these risk fac- tors of 0.0005 and 0.0004 latent cancer fatality (LCF) for each person-rem of radiation exposure to the general public and worker popu- lation, respectively, for doses less than 20 rem. The factor for the population is slightly higher due to the presence of infants and children who are more sensitive to radiation than the adult worker population.

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.).

Chemical and physical properties of gas jets in comets: II. Modeling OH, CN and C2 jets in Comet C/1995 O1 (Hale–Bopp) one month after perihelion  

Science Journals Connector (OSTI)

We present an analysis of OH, CN, and C2 jets observed in Comet Hale–Bopp during April 22–26, 1997. We conclude that an extended source, which peaks in productivity after a certain amount of time has passed after being released from the nucleus (8.5, 2.5, and 42.6 × 10 4   s , respectively) is responsible for the observed coma jet morphology in all three species. Sub-micron organic grains are the favored explanation for the extended source. Our models indicate that this extended source produces approximately 40% of the OH, 50% of the C2, and 75% of the CN. The balance for each species is created by a diffuse nuclear gas source. Compared with the nuclear gas source and normalized to the CN abundance, the composition of the extended source is depleted in OH by a factor of ?6, and depleted in C2 by a factor of ?2. The existence of anti-sunward jets do not require production of radicals throughout the cometary night. Instead, our model demonstrates that active areas exposed to near-twilight conditions throughout the comet's rotational period can produce the observed anti-sunward morphology.

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 [Office of Scientific and Technical Information (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 (OSTI)

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.

Counter-anion role in the formation of two supra­molecular complexes: [Ag2(DPP)2](ClO4)2?CH3CN and [Ag2(DPP)2(NO3)2] {DPP is N-[(di­phenyl­phosphanyl)methyl]pyridin-4-amine}  

Science Journals Connector (OSTI)

In the Ag complex of N-[(di­phenyl­phosphanyl)methyl]pyridin-4-amine (DPP) with perchlorate, the unique Ag+ cation has a near-linear coordination geometry consisting of one pyridine N atom and one P atom from two different DPP ligands. In the analogous complex with nitrate, the nitrate anions weakly chelate to each Ag+ cation, leading to each Ag+ cation having a distorted tetra­hedral coordination geometry consisting of one pyridine N atom and one P atom from two different DPP ligands, and two chelating nitrate O atoms.

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 (OSTI)

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 (OSTI)

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 (OSTI)

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.

Effect of Spin-Crossover-Induced Pore Contraction on CO{sub 2}-Host Interactions in the Porous Coordination Polymers [Fe(pyrazine)M(CN){sub 4}] (M = Ni, Pt)  

SciTech Connect (OSTI)

Variable-temperature in situ ATR-FTIR spectra are presented for the porous spin-crossover compounds [Fe(pyrazine)- Ni(CN){sub 4}] and [Fe(pyrazine)Pt(CN){sub 4}] under CO{sub 2} pressures of up to 8 bar. Significant shifts in the ?{sub 3} and ?{sub 2} IR absorption bands of adsorbed CO{sub 2} are observed as the host materials undergo transition between low- and high-spin states. Computational models used to determine the packing arrangement of CO{sub 2} within the pore structures show a preferred orientation of one of the adsorbed CO{sub 2} molecules with close O=C=O···H contacts with the pyrazine pillar ligands. The interaction is a consequence of the commensurate distance of the inter-pyrazine separations and the length of the CO{sub 2} molecule, which allows the adsorbed CO{sub 2} to effectively bridge the pyrazine pillars in the structure. The models were used to assign the distinct shifts in the IR absorption bands of the adsorbed CO{sub 2} that arise from changes in the O=C=O···H contacts that strengthen and weaken in correlation with changes in the Fe–N bond lengths as the spin state of Fe changes. The results indicate that spin-crossover compounds can function as a unique type of flexible sorbent in which the pore contractions associated with spin transition can affect the strength of CO{sub 2}–host interactions.

Temperature measurement of an atmospheric pressure arc discharge plasma jet using the diatomic CN (B {sup 2}{sigma}{sup +}-X {sup 2}{sigma}{sup +}, violet system) molecular spectra  

SciTech Connect (OSTI)

The CN (B {sup 2}{sigma}{sup +}-X {sup 2}{sigma}{sup +}) molecular emission spectrum is used to measure both the vibrational and rotational temperatures in atmospheric pressure arc jet discharges. The vibrational and rotational temperature effects on the synthetic diatomic molecular spectra were investigated from the (v{sup '},v{sup ''})=(0,0) band to the (5,5) band. The temperatures obtained from the synthetic spectra compared with the experimental result of a low-frequency arc discharge show a vibrational temperature of (4250-5010) K and a rotational temperature of (3760-3980) K for the input power in the range of (80-280) W. As the (0,0) band is isolated from other vibrational transition bands, determination of the rotational temperature is possible based only on the (0,0) band, which simplifies the temperature measurement. From the result, it was found that the CN molecular spectrum can be used as a thermometer for atmospheric pressure plasmas containing carbon and nitrogen.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 Å). 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 (OSTI)

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.

Electronic Structure of TiO2/CH3NH3PbI3 Perovskite Solar Cell Interfaces  

Science Journals Connector (OSTI)

The last two decades, the research on different types of mesoscopic solar cells has grown enormously, largely because this family of solar cells can be controlled in many different ways and for their easy production. ... Recently, the use of soluble semiconductors such as organic–inorganic perovskites has shown great promise as light absorbers in solid-state mesoscopic solar cells. ... We report for the first time on a hole conductor-free mesoscopic methylammonium lead iodide (CH3NH3PbI3) perovskite/TiO2 heterojunction solar cell, produced by deposition of perovskite nanoparticles from a soln. of CH3NH3I and PbI2 in ?-butyrolactone on a 400 nm thick film of TiO2 (anatase) nanosheets exposing (001) facets. ...

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 (OSTI)

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.

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 Å. 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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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 (OSTI)

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}.

Laboratory Investigations of a Low-swirl Injector withH2 and CH4 at Gas

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 (OSTI)

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 (OSTI)

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.

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.

New k-phase materials, k-(ET) sub 2 Cu(N(CN) sub 2 )X: X = Cl, Br and I: The synthesis, structure and superconductivity above 11 K in the Cl ( Tc = 12. 8 K, 0. 3 kbar) and Br( Tc = 11. 6 K) salts  

SciTech Connect (OSTI)

The syntheses, structures, selected physical properties, and band electronic structures of three copper (I) dicyanamide halide salts of bis(ethylenedithio)tetrathiafulvalene ({kappa}-(ET){sub 2}Cu(N(CN){sub 2})X, where X = Cl, Br, and I) are discussed. X-ray crystallographic studies demonstrate that the three derivatives are isostructural. The bromide salt is an ambient pressure superconductor with an inductive onset at 11.6 K and a resistive onset at 12.5 K. {kappa}-(ET){sub 2}Cu(N(CN){sub 2})Cl exhibits the highest reported superconducting transition temperature ({Tc} = 12.8 K, 0.3 kbar) for an organic superconductor, once a semiconductor-semiconductor transition (42 K) is suppressed. The application of GE varnish or Apiezon N grease to crystals of {kappa}-(ET){sub 2}Cu(N(CN){sub 2})Cl provides sufficient stress to induce superconductivity at ambient pressure.'' Crystals of the iodide remain metallic to {approximately}150 K, where they become weakly semiconductive. No sign of superconductivity was detected at pressures (hydrostatic and shearing) up to 5.2 kbar and at temperatures as low as 1.1 K. The band electronic structures of the three salts are essentially identical. The differences in superconducting properties are explained in terms of differences in lattice softness, which are strongly influenced by short C-H{hor ellipsis}donor and C-H{hor ellipsis}anion contacts. 17 refs., 2 figs.

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

SciTech Connect (OSTI)

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 (OSTI)

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 (OSTI)

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.

The European land and inland water CO2, CO, CH4 and N2O balance between 2001 and 2005  

SciTech Connect (OSTI)

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 (OSTI)

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.

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

SciTech Connect (OSTI)

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.

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 (OSTI)

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 (OSTI)

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}.
