Although the smaller domains provide moderate transport pathways, their effectiveness remains low due to strong, resistive water molecules/domain surface interactions. The water occupancy of the larger domains yields bulk-like water, and causes the observed transition in the water uptake and significant increases in transport properties.

MoO3 trapping layers with CF4 plasma treatment in flash memory applications  

Science Journals Connector (OSTI)

Abstract In this research, we used MoO3 with CF4 plasma treatment as charge trapping layer in metal-oxide-high-k -oxide-Si-type memory. We analyzed material properties and electrical characteristics with multiple analyses. The plasma treatment could increase the trapping density, reduce the leakage current, expand band gap, and passivate the defect to enhance the memory performance. The MoO3 charge trapping layer memory with suitable CF4 plasma treatment is promising for future nonvolatile memory applications.

Self-assembled porous MoO2/graphene microspheres towards high performance anodes for lithium ion batteries  

Science Journals Connector (OSTI)

Abstract Three dimensional (3D) porous self-assembled MoO2/graphene microspheres are successfully synthesized via microwave-assisted hydrothermal process in a short reaction time followed by thermal annealing. Such rationally designed multifunctional hybrid nanostructure is constructed from interconnected MoO2 nanoparticles (35nm), which is self-assembled into ordered nanoporous microspheres via strong electrostatic attraction between graphene sheets and MoO2 nanoparticles. The MoO2/graphene hybrid structure delivers a high reversible capacity with significantly enhanced cycling stability (?1300mAhg?1 after 80 cycles at C/10 rate) and excellent rate capability (913 and 390mAhg?1 at 2C and 5C rates, respectively), when used as an anode material. The microspheres are interconnected and well encapsulated by the flexible graphene sheets, which not only accommodates large volume change but also increases the electrical conductivity of the hybrid structure. Moreover, nanoporous voids present in the 3D framework facilitate effective electrolyte penetration and make a direct contact with the active MoO2 nanoparticles, thereby greatly enhancing lithium ion transport. The strategic combination of self-assembly, nanoporous voids, 3D network and intriguing properties of graphene sheets provides excellent electrochemical performance as anode materials for Lithium ion battery applications.

Phase-change-related degradation of catalyst layers in Phase-change-related degradation of catalyst layers in proton-exchange-membrane fuel cells Title Phase-change-related degradation of catalyst layers in proton-exchange-membrane fuel cells Publication Type Journal Article Year of Publication 2013 Authors Hwang, Gi Suk, Hyoungchul Kim, Roger Lujan, Rangachary Mukundan, Dusan Spernjak, Rodney L. Borup, Massoud Kaviany, Moo Hwan Kim, and Adam Z. Weber Journal Electrochimica Acta Volume 95 Pagination 29 - 37 Date Published 4/2013 ISSN 00134686 Keywords degradation, Environmental scanning electron microscope (ESEM), Freeze/thaw cycle, Membrane electrode assembly (MEA), Nanostructured thin film (NSTF), Pt/C dispersion Abstract Understanding and optimizing water and thermal management in the catalyst layer of proton-exchange-membrane fuel cells is crucial for performance and durability improvements. This is especially the case at low temperatures, where liquid water and even ice may exist. In this article, the durability of a traditional Pt/C dispersed and a nanostructure thin film (NSTF) membrane-electrode assembly (MEA) are examined under wet/dry and freeze/thaw cycles using both in situ and ex situ experiments. Multiple isothermal cold starts result in a performance degradation for the dispersed MEA, while no such a degradation is found in the NSTF. The results are consistent with stand-alone MEA tests, wherein the dispersed catalyst layer results in an exponential increase in the number and size of cracks until it delaminates from the membrane due to the impact of the freeze/thaw process within the catalyst-layer pores. The NSTF catalyst layer shows minimal crack generation without delamination since the ice forms on top of the layer. The results are useful for understanding degradation due to phase-change containing cycles.

Large lithium molybdate (Li$_2$MoO$_4$) crystal boules were produced by using the low thermal gradient Czochralski growth technique from deeply purified molybdenum. A small sample from one of the boules was preliminary characterized in terms of X-ray-induced and thermally-excited luminescence. A large cylindrical crystalline element (with a size of $\\oslash 40\\times40$ mm) was used to fabricate a scintillating bolometer, which was operated aboveground at $\\sim 15$ mK by using a pulse-tube cryostat housing a high-power dilution refrigerator.

Lithium-active molybdenum trioxide coated LiNi0.5Co0.2Mn0.3O2 cathode material with enhanced electrochemical properties for lithium-ion batteries  

Science Journals Connector (OSTI)

Abstract LiNi0.5Co0.2Mn0.3O2 cathode material was coated with MoO3 via a wet coating process. X-ray diffraction patterns show that the coating surface is composed of MoO3 and Li2MoO4. The 3wt.% MoO3 coated LiNi0.5Co0.2Mn0.3O2 cathode (Li2MoO4 is treated as equivalent mole of MoO3) exhibits the best improved cycling performance. It performs a capacity retention of 90.9% after 100 cycles while that of the pristine material is only 82.8%. After being coated by 3wt.% MoO3, the rate performance is also greatly enhanced and the charge transfer resistance is greatly decreased. The improvement of electrochemical performance is related to the fact that the coating layer diminishes the side reactions between the cathode and the electrolyte.

ANTS: a new Collaborative Learning Framework  

E-Print Network (OSTI)

CSCW and MOO environments have played an important role in CSCL research. These multi-user community-ware frameworks enhance social interactions and shared experience and thus enabling new CSCL research. We however find some limitations in existing platforms: technology limitations and a lack of solid collaborative services. We present ANTS: a collaborative framework that aims to provide a solid foundation for CSCL applications. In one side, the framework is constructed on top of cutting-edge technologies like J2EE (EJB, JSP, Servlets), Notification services (Elvin, JMS) and XML. In the other side, ANTS provides solid CSCW services that make the system robust and extensible. We also present a concrete ANTS extension: JLE, a collaborative learning environment including services like course management, assessment management, collaboration, progress tracking and tutorware.

Characteristics of V2O5/Ti-PILC catalyst for the reduction of NO by NH3  

Science Journals Connector (OSTI)

Titania-pillared clay (Ti-PILC) as a catalyst support exhibited peculiar physicochemical characteristics compared to that of titania for the reduction of NO by NH3. The morphological variation of Ti-PILC was examined with respect to the preparation method. For the freeze-dried Ti-PILC, the development of needle-like crystallites, which may reveal the formation of a house-of-cards structure by delamination of Ti-PILC, has been observed. Ti-PILC catalyst contains high surface acidity examined by NH3 TPD. Without the impregnation of WO3 and MoO3 on V2O5/Ti-PILC catalyst as a promoter, the catalyst exhibits competitive NO removal performance to a commercial V2O5-WO3/TiO2 catalyst. In addition, Ti-PILC catalyst also exhibits the strong sulfur tolerance mainly attributed to the unique pore structure of the catalyst.

Shift in the longitudinal sound velocity due to sliding charge-density waves  

Science Journals Connector (OSTI)

The nonlinear conductivity observed for moderate electric fields in NbSe3, TaS3, (TaS4)2I, and K0.3MoO3 below the charge-density-wave-transition is believed to be due to the sliding of the charge-density waves. The sliding motion leads to a Doppler shift of the x-ray diffraction peaks, but this effect has not yet been resolved. We show here that besides the Doppler shift, a sliding incommensurate charge-density wave causes a change in the longitudinal sound velocity of the crystal that is linear in the charge-density-wave velocity. The resulting anisotropic shift is estimated in a mean-field approximation and found to be experimentally observable.

Heat Flux Analysis of a Reacting Thermite Spray Impingent on a Substrate  

SciTech Connect

Spray combustion from a thermite reaction is a new area of research relevant to localized energy generation applications, such as welding or cutting. In this study, we characterized the heat flux of combustion spray impinging on a target from a nozzle for three thermite mixtures. The reactions studied include aluminum (Al) with iron oxide (Fe2O3), Al with copper oxide (CuO), and Al with molybdenum oxide (MoO3). Several standoff distances (i.e., distance from the nozzle exit to the target) were analyzed. A fast response heat flux sensor was engineered for this purpose and is discussed in detail. Results correlated substrate damage to a threshold heat flux of 4550 W/cm2 for a fixed-nozzle configuration. Also, higher gas-generating thermites were shown to produce a widely dispersed spray and be less effective at imparting kinetic energy damage to a target. These results provide an understanding of the role of thermal and physical properties (i.e., such as heat of combustion, gas generation, and particle size) on thermite spray combustion performance measured by damaging a target substrate.

Propane ammoxidation over MoVTeNbO M1 phase: Density functional theory study of propane oxidative dehydrogenation steps  

Science Journals Connector (OSTI)

Abstract Propane ammoxidation to acrylonitrile catalyzed by the bulk MoVTeNb oxides has received considerable attention because it is more environmentally benign than the current process of propylene ammoxidation and relies on a more abundant feedstock. This process is proposed to consist of a series of elementary steps including propane oxidative dehydrogenation (ODH), ammonia and O2 activation, \\{NHx\\} insertion into C3 surface intermediates, etc. Density functional theory calculations were performed here to investigate the three sequential H abstraction steps that successively convert propane into isopropyl, propene, and ?-allyl on cation sites in the proposed selective and active center present in the ab plane of the MoVTeNbO M1 phase. The initial H abstraction from propane was found to be the rate-limiting step of this process, consistent with both the proposed reaction mechanism for propane ammoxidation on the MoVTeNb oxides and current understanding of V5+ as the active site for alkane activation on V-based oxides. Te=O was found to be significantly more active than V5+=O for the H abstraction from propane, which suggests that the surface and bulk Te species may be different. The role of Mo=O is most likely limited to being an H acceptor from isopropyl to form propene under ammoxidation conditions.

Final Report: Catalytic Hydrocarbon Reactions over Supported Metal Oxides, August 1, 1995 - July 31, 1999  

SciTech Connect

The research program focused on the catalysis of hydrodesulfurization (HDS) over molybdenum-based catalysts and how catalyst composition, redox ability, structure and neighboring sites control the catalytic properties of metal oxides. We sought to understand the catalytic features/sites that control hydrogenation, hydrogenolysis, and isomerization during HDS. Unprompted silica-supported molybdenum oxides and molybdenum sulfides were studied. Model catalyst systems were prepared from organometallic precursors or cluster compounds to generate supported structures that feature Mo(II) and Mo(IV) cations that are isolated or in ensembles and that have either Mo-O or Mo-S bonds. Conventional MOS{sub 2} catalysts, which contain both edge and rim sites, were be studied. Finally, single-layer MOS{sub 2} structures were also prepared from 2H-MoS{sub 2} powder so that the model systems could be compared against a disulfide catalyst that only involves rim sites. Catalytic reactions for thiophene and tetrahydrothione were studied over the various catalysts. Oxidation states were determined using X-ray photoelectron spectroscopy. X-ray crystallography was used to characterize and follow changes in the MOS{sub 2} structures. The program on metal oxides prepared supported oxides that have a specific structure and oxidation state to serve as model templates for the more complex commercial catalysts and then employed these structures in reaction studies. This focus area examined the relationships between structure and cation redox characteristics in oxidation catalysis. Infrared and Raman spectroscopy were used to characterize the cations and reaction intermediates.

A synchroton single crystal X-ray structure determination of (NH4)3Mo4P3O16: A microporous molybdenum phosphate with Mo4O6+4 cubes  

Science Journals Connector (OSTI)

Reaction of MoO3, Mo, (NH4)2HPO4, H3PO4, and H2O in a mole ratio of 1.4:1:3.6:6:120 at 360C for 16 hr gives a nearly quantitative yield of black cubes of (NH4)3Mo4P3O16 (1). The structure of (1) was solved from data collected on a 30 30 30 ?m3 crystal at the National Synchrotron Light Source at Brookhaven National Laboratory. The compound is cubic, space group P43m, with a = 7.736(2) , and was refined to residuals of R(Rw) = 0.035(0.049). Phosphate (1) is isotypic with Cs3Mo4P3O16 and is related to the iron arsenate mineral pharmacosiderite. Unlike the Cs+ compound, (1) can be rendered microporous by thermal removal of the NH+4 cations to give ammonia with the charge compensating proton remaining behind in the lattice. Water absorption isotherms show the reversible uptake of 5.6 wt% water, which corresponds to over 15 vol% void space in (1) after the NH3 removal. The framework consists of Mo4O6+4 cubes, with six Mo?Mo contacts of 2.570(4) , joined together together by (PO4)62 along ?100? to form a 3-D network composed of tetramers of triply edge-sharing Mo-centered octahedra and phosphate groups alternating along all ?100? directions. The windows and cavities in (1) are large enough that the NH+4 cations occupy several different positions in the unit cell.

Electronic Structure Description of the Cis-MoOS Unit in Models for Molybdenum Hydroxylases  

SciTech Connect

The molybdenum hydroxylases catalyze the oxidation of numerous aromatic heterocycles and simple organics and, unlike other hydroxylases, utilize water as the source of oxygen incorporated into the product. The electronic structures of the cis-MoOS units in CoCp{sub 2}[Tp{sup iPr}Mo{sup V}OS(OPh)] and Tp{sup iPr}Mo{sup VI}OS(OPh) (Tp{sup iPr} = hydrotris(3-isopropylpyrazol-1-yl)borate), new models for molybdenum hydroxylases, have been studied in detail using S K-edge X-ray absorption spectroscopy, vibrational spectroscopy, and detailed bonding calculations. The results show a highly delocalized Mo {double_bond} S {pi}* LUMO redox orbital that is formally Mo(d{sub xy}) with {approx}35% sulfido ligand character. Vibrational spectroscopy has been used to quantitate Mo-S{sub sulfido} bond order changes in the cis-MoOS units as a function of redox state. Results support a redox active molecular orbital that has a profound influence on MoOS bonding through changes to the relative electro/nucleophilicity of the terminal sulfido ligand accompanying oxidation state changes. The bonding description for these model cis-MoOS systems supports enzyme mechanisms that are under orbital control and dominantly influenced by the unique electronic structure of the cis-MoOS site. The electronic structure of the oxidized enzyme site is postulated to play a role in polarizing a substrate carbon center for nucleophilic attack by metal activated water and acting as an electron sink in the two-electron oxidation of substrates.

Regional Slip Tendency Analysis of the Great Basin Region  

DOE Data Explorer (OSTI)

- The resulting along?fault and fault?to?fault variation in slip or dilation potential is a proxy for along fault and fault?to?fault variation in fluid flow conduit potential. Stress Magnitudes and directions were calculated across the entire Great Basin. Stress field variation within each focus area was approximated based on regional published data and the world stress database (Hickman et al., 2000; Hickman et al., 1998 Robertson?Tait et al., 2004; Hickman and Davatzes, 2010; Davatzes and Hickman, 2006; Blake and Davatzes 2011; Blake and Davatzes, 2012; Moeck et al., 2010; Moos and Ronne, 2010 and Reinecker et al., 2005). The minimum horizontal stress direction (Shmin) was contoured, and spatial bins with common Shmin directions were calculated. Based on this technique, we subdivided the Great Basin into nine regions (Shmin <070, 070140). Slip and dilation tendency were calculated using 3DStress for the faults within each region using the mean Shmin for the region. Shmin variation throughout Great Basin are shown on Figure 3. For faults within the Great Basin proper, we applied a normal faulting stress regime, where the vertical stress (sv) is larger than the maximum horizontal stress (shmax), which is larger than the minimum horizontal stress (sv>shmax>shmin). Based on visual inspection of the limited stress magnitude data in the Great Basin, we used magnitudes such that shmin/shmax = .527 and shmin/sv= .46. These values are consistent with stress magnitude data at both Dixie Valley (Hickman et al., 2000) and Yucca Mountain (Stock et al., 1985). For faults within the Walker Lane/Eastern California Shear Zone, we applied a strike?slip faulting stress, where shmax > sv > shmin. Upon visual inspection of limited stress magnitude data from the Walker Lane and Eastern California Shear zone, we chose values such that SHmin/SHmax = .46 and Shmin/Sv= .527 representative of the region. Results: The results of our slip and dilation tendency analysis are shown in Figures 4 (dilation tendency), 5 (slip tendency) and 6 (slip tendency + dilation tendency). Shmin varies from northwest to east?west trending throughout much of the Great Basin. As such, north? to northeast?striking faults have the highest tendency to slip and to dilate, depending on the local trend of shmin. These results provide a first order filter on faults and fault systems in the Great Basin, affording focusing of local?scale exploration efforts for blind or hidden geothermal resources.

Propane ammoxidation over the Mo-V-Te-Nb-O M1 phase: Reactivity of surface cations in hydrogen abstraction steps  

SciTech Connect

Density functional theory calculations (GGA-PBE) have been performed to investigate the adsorption of C3 (propane, isopropyl, propene, and allyl) and H species on the proposed active center present in the surface ab planes of the bulk Mo-V-Te-Nb-O M1 phase in order to better understand the roles of the different surface cations in propane ammoxidation. Modified cluster models were employed to isolate the closely spaced V=O and Te=O from each other and to vary the oxidation state of the V cation. While propane and propene adsorb with nearly zero adsorption energy, the isopropyl and allyl radicals bind strongly to V=O and Te=O with adsorption energies, {Delta}E, being {le} -1.75 eV, but appreciably more weakly on other sites, such as Mo=O, bridging oxygen (Mo-O-V and Mo-O-Mo), and empty metal apical sites ({Delta}E > -1 eV). Atomic H binds more strongly to Te = O ({Delta}E {le} -3 eV) than to all the other sites, including V = O ({Delta}E = -2.59 eV). The reduction of surface oxo groups by dissociated H and their removal as water are thermodynamically favorable except when both H atoms are bonded to the same Te=O. Consistent with the strong binding of H, Te=O is markedly more active at abstracting the methylene H from propane (E{sub a} {le} 1.01 eV) than V = O (E{sub a} = 1.70 eV on V{sup 5+} = O and 2.13 eV on V{sup 4+} = O). The higher-than-observed activity and the loose binding of Te = O moieties to the mixed metal oxide lattice of M1 raise the question of whether active Te = O groups are in fact present in the surface ab planes of the M1 phase under propane ammoxidation conditions.

On the Reaction Mechanism of Acetaldehyde Decomposition on Mo(110)  

SciTech Connect

The strong Mo-O bond strength provides promising reactivity of Mo-based catalysts for the deoxygenation of biomass-derived oxygenates. Combining the novel dimer saddle point searching method with periodic spin-polarized density functional theory calculations, we investigated the reaction pathways of a acetaldehyde decomposition on the clean Mo(110) surface. Two reaction pathways were identified, a selective deoxygenation and a nonselective fragmentation pathways. We found that acetaldehyde preferentially adsorbs at the pseudo 3-fold hollow site in the ?2(C,O) configuration on Mo(110). Among four possible bond (?-C-H, ?-C-H, C-O and C-C) cleavages, the initial decomposition of the adsorbed acetaldehyde produces either ethylidene via the C-O bond scission or acetyl via the ?-C-H bond scission while the C-C and the ?-C-H bond cleavages of acetaldehyde leading to the formation of methyl (and formyl) and formylmethyl are unlikely. Further dehydrogenations of ethylidene into either ethylidyne or vinyl are competing and very facile with low activation barriers of 0.24 and 0.31 eV, respectively. Concurrently, the formed acetyl would deoxygenate into ethylidyne via the C-O cleavage rather than breaking the C-C or the C-H bonds. The selective deoxygenation of acetaldehyde forming ethylene is inhibited by relatively weaker hydrogenation capability of the Mo(110) surface. Instead, the nonselective pathway via vinyl and vinylidene dehydrogenations to ethynyl as the final hydrocarbon fragment is kinetically favorable. On the other hand, the strong interaction between ethylene and the Mo(110) surface also leads to ethylene decomposition instead of desorption into the gas phase.

Regional Slip Tendency Analysis of the Great Basin Region  

SciTech Connect

Slip and dilation tendency on the Great Basin fault surfaces (from the USGS Quaternary Fault Database) were calculated using 3DStress (software produced by Southwest Research Institute). Slip and dilation tendency are both unitless ratios of the resolved stresses applied to the fault plane by the measured ambient stress field. - Values range from a maximum of 1 (a fault plane ideally oriented to slip or dilate under ambient stress conditions) to zero (a fault plane with no potential to slip or dilate). - Slip and dilation tendency values were calculated for each fault in the Great Basin. As dip is unknown for many faults in the USGS Quaternary Fault Database, we made these calculations using the dip for each fault that would yield the maximum slip or dilation tendency. As such, these results should be viewed as maximum slip and dilation tendency. - The resulting along?fault and fault?to?fault variation in slip or dilation potential is a proxy for along fault and fault?to?fault variation in fluid flow conduit potential. Stress Magnitudes and directions were calculated across the entire Great Basin.
