Glycerol Hydrogenolysis on Carbon-Supported PtRu and AuRu Bimetallic Catalysts  

SciTech Connect

Bimetallic PtRu and AuRu catalysts were prepared by a surface redox method in which Pt or Au was deposited onto the surface of carbon-supported Ru nanoparticles with an average diameter of 2-3 nm. Characterization by H2 chemisorption, analytical TEM, and X-ray absorption spectroscopy at the Ru K-edge, Pt LIII-edge, and Au LIII-edge confirmed that Pt and Au were successfully deposited onto Ru without disrupting the Ru particles. Depression of the ethane hydrogenolysis rate over Ru after addition of Au provided further evidence of successful deposition. The bimetallic particles were subsequently evaluated in the aqueous-phase hydrogenolysis of glycerol at 473 K and 40 bar H2 at neutral and elevated pH. Although monometallic Pt and Ru exhibited different activities and selectivities to products, the bimetallic PtRu catalyst functioned more like Ru. A similar result was obtained for the AuRu bimetallic catalyst. The PtRu catalyst appeared to be stable under the aqueous-phase reaction conditions, whereas the AuRu catalyst was altered by the harsh conditions. Gold appeared to migrate off the Ru and agglomerate on the carbon during the reaction in liquid water.

SUPPORT FOR HU CFRT SUMMER HIGH SCHOOL FUSION WORKSHOP  

SciTech Connect

Nine summer fusion science research workshops for minority and female high school students were conducted at the Hampton University Center for Fusion Research and Training from 1996 to 2005. Each workshop was of the duration of eight weeks. In all 35 high school students were mentored. The students presented 28 contributed papers at the annual meetings of the American Physical Society Division of Plasma Physics. These contributed papers were very well received by the plasma physics and fusion science research community. The students won a number of prestigious local, state, and national honors, awards, prizes, and scholarships. The notable among these are the two regional finalist positions in the 1999 Siemens-Westinghouse Science and Technology Competitions; 1st Place U.S. Army Award, 2006; 1st Place U.S. Naval Science Award, 2006; Yale Science and Engineering Association Best 11th Grade Project, 2006; Society of Physics Students Book Award, 2006; APS Corporate Minority Scholarship and others. This workshop program conducted by the HU CFRT has been an exemplary success, and served the minority and female students exceptionally fruitfully. The Summer High School Fusion Science Workshop is an immensely successful outreach activity conducted by the HU CFRT. In this workshop, we train, motivate, and provide high quality research experiences to young and talented high school scholars with emphasis on under-represented minorities and female students in fusion science and related areas. The purpose of this workshop is to expose minority and female students to the excitement of research in science at an early stage in their academic lives. It is our hope that this may lead the high school students to pursue higher education and careers in physical sciences, mathematics, and perhaps in fusion science. To our knowledge, this workshop is the first and only one to date, of fusion science for under-represented minorities and female high school students at an HBCU. The faculty researchers in the HU CFRT mentor the students during summers. Mentors spend a considerable amount of time and efforts in training, teaching, guiding and supervising research projects. The HU CFRT has so far conducted nine workshops during the summers of 1996-2000 and 2002-2005. The first workshop was conducted in summer 1996. Students for the workshop are chosen from a national pool of exceptionally talented high school rising seniors/juniors. To our knowledge, most of these students have gone on to prestigious universities such as Duke University, John Hopkins University, CalTech, UCLA, Hampton University, etc. after completing their high school. For instance, Tiffany Fisher, participant of the 1996 summer workshop completed her BS in Mathematics at Hampton University in May 2001. She then went on to Wake Forest University at Winston-Salem, North Carolina to pursue graduate studies. Anshul Haldipur, participant of the 1999 summer workshop, began his undergraduate studies at Duke University in 2000. Christina Nguyen and Ilissa Martinez, participants of the 2000 summer workshop, are pursuing their undergraduate degrees at the UCLA and Florida State University respectively. The organizing committee of the APS DPP annual meeting invited Dr. Punjabi to deliver an invited talk on training the next generation of fusion scientists and engineers at the 2005 APS DPP meeting in Denver, CO. The organizing committee distributed a special flier with the Bulletin to highlight this invited talk and another talk on education as well the expo. This has given wide publicity and recognition to our workshops and Hampton University. Prof. Punjabi's talk: 'LI2 2: Training the next generation of fusion scientists and engineers: summer high school fusion science workshop, Bull. Amer. Phys. Soc. 50, 221 (2005)' was very well-received. He talked about HU education and outreach initiative and the HU CFRT Summer High School Workshop. The audience had a considerable number of questions about our workshops and the High School to PhD Pipeline in fusion science. Professor William Mathews of

Graphene on Ru(0001): Evidence for two graphene band structures  

SciTech Connect

High-resolution photoemission illustrates that the band structure of graphene on Ru(0001) exhibits a well-defined splitting. This splitting is largest with the graphene directly on the Ru(0001) substrate, whereas with a chemisorbed oxygen spacer layer between the graphene and the metal substrate, this splitting is considerably reduced. This splitting is attributed to a combination of chemical interactions between graphene and Ru(0001) and to screening of the former by the latter, not spin-orbit coupling.

-Arm flexibility of HU from Staphylococcus aureus dictates the DNA-binding and recognition mechanism  

Science Journals Connector (OSTI)

Structural analysis of apo and DNA-bound HU from S. aureus (SHU) revealed that conformational changes occur in both the protein and DNA upon DNA binding. Base-readout and shape-readout mechanisms are involved in DNA binding and recognition by SHU, in which -arm flexibility is a major determinant.

The interactions of water and perfluorodiethyl ether on Ru(100)  

SciTech Connect

We have studied the interactions of water and perfluorodiethyl ether on Ru(100) in order to model the effects of surface structure and humidity on the bonding and decomposition of perfluoroalkyl ether lubricants with metal surfaces. In order to understand the interactions on Ru(100), we have first investigated the interactions of each of these adsorbates alone on the clean surface. The interactions of water with Ru(100) have been studied using both thermal desorption spectroscopy (TDS) and electron energy loss spectroscopy (EELS). From these studies we conclude that a small amount of water dissociates on this surface (5--10% of a monolayer), but water is adsorbed in a predominantly molecular form on this surface with an increasing degree of hydrogen-bonding with increasing coverage. The effects of hydrogen and oxygen coadsorption on the interactions of water with this surface have also been studied using TDS. Finally, the interactions of coadsorbed water and perfluorodiethyl ether on Ru(100) have been investigated using TDS.

CO adsorption on ion-exchanged Ru zeolite catalysts, studied by IR spectroscopy, revealed the existence of three types of ruthenium which adsorbed the carbon monoxide into three different states. The ruthenium types were atomically or highly dispersed ruthenium, ruthenium clusters which formed ruthenium carbonyl, and larger (> 1 nm) particles, probably on the outer zeolite surfaces.

Search for 2? decays of 96Ru and 104Ru by ultralow-background HPGe ? spectrometry at LNGS: Final results  

Science Journals Connector (OSTI)

An experiment to search for double-? decay processes in 96Ru and 104Ru, which are accompanied by ? rays, has been realized in the underground Gran Sasso National Laboratories of the I.N.F.N. (Italy). Ruthenium samples with masses of ?0.50.7 kg were measured with the help of ultralow-background high-purity Ge ?-ray spectrometry. After 2162 h of data taking the samples were deeply purified to reduce the internal contamination of 40K. The last part of the data has been accumulated over 5479 h. New improved half-life limits on 2?+/??+/2? processes in 96Ru have been established on the level of 1020 yr, in particular for decays to the ground state of 96Mo: T1/22?2?+?1.41020 yr, T1/22???+?8.01019 yr, and T1/20?2K?1.01021 yr (all limits are at 90% C.L.). The resonant neutrinoless double-electron captures to the 2700.2 and 2712.7keV excited states of 96Mo are restricted as T1/20?KL?2.01020 yr and T1/20?2L?3.61020 yr, respectively. Various two-neutrino and neutrinoless 2? half-lives of 96Ru have been estimated in the framework of the quasiparticle random-phase approximation approach. In addition, the T1/2 limit for 0?2?? transitions of 104Ru to the first excited state of 104Pd has been set as ?6.51020 yr.

The alpha-cluster model applied to {sup 96}Ru  

SciTech Connect

The states of {sup 96}Ru are investigated in terms of the a alpha+ core structure. The ground state band of the alpha+{sup 92}Mo system is obtained through a local cluster-core potential which includes a fixed set of parameters employed in other mass regions. The calculated spectrum gives a good general description of the experimental {sup 96}Ru levels. The reduced alpha-widths, B(E2) transition rates and rms intercluster separations are determined for the members of the ground state band. The results show that the model can reproduce the order of magnitude of the experimental B(E2) values without the use of effective charges and indicate that the first members of the ground state band present a stronger alpha-cluster character. Predictions concerning a negative parity band of the alpha+{sup 92}Mo system are also shown.

High-temperature phases of SrRuO3  

Science Journals Connector (OSTI)

The crystal structure of SrRuO3 at high temperatures has been studied using powder neutron diffraction and the Rietveld method. It was determined that from 300 K to approximately 820 K the structure of SrRuO3 is orthorhombic (Pbnm). The material then undergoes a phase transition and becomes tetragonal (I4/mcm) between ?820 and 920 K. The high-temperature (>920 K) structure was found to be the standard cubic perovskite (Pm3m). From the neutron-diffraction data and the space group assignments, the orthorhombic to tetragonal phase transition must be first order, while the transition from the tetragonal to cubic phase is consistent with a second-order phase transition.

Dimerization Induced Deprotonation of Water on RuO2(110)  

SciTech Connect

RuO2 has proven to be indispensable as a co-catalyst in numerous systems designed for photocatalytic water splitting. In this study we have carried out a detailed mechanistic study of water behavior on the most stable RuO2 face, RuO2(110), by employing variable temperature scanning tunneling microscopy and density functional theory calculations. We show that water monomers adsorb molecularly on Ru sites, become mobile above 238 K, diffuse along the Ru rows and form water dimers. The onset for dimer diffusion is observed at ~277 K indicating significantly higher diffusion barrier than that for monomers. More importantly, we find that water dimers deprotonate readily to form Ru-bound H3O2 and bridging OH species. The observed behavior is compared and contrasted with that observed for water on isostructural rutile TiO2(110).

The kinetics of CO poisoning in simulated reformate and effect of Ru island morphology on PtRu fuel cell catalysts as determined by operando XANES  

SciTech Connect

In situ X-ray absorption spectroscopy (XAS) measurements, including both X-ray absorption near edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS), were carried out on commercially produced Pt and PtRu bimetallic electrocatalysts as well as on a mechanically mixed PtRu bimetallic electrocatalyst in an operating fuel cell in H{sub 2} doped with 150 ppm CO. By use of the novel {Delta}XANES technique, the coverages of CO and ontop and n-fold H (overpotential deposited and underpotential deposited hydrogen) are obtained and compared for the three catalysts, and the results are correlated with PtRu cluster morphology. The mechanical mixing process used to create the bimetallic PtRu catalyst is found to maximize CO tolerance, although the PtRu commercial electrocatalyst exhibits an increased electronic effect, most probably due to the presence of Ru(O){sub x} islands at the catalyst surface. The mobility of the CO on both Ru and Pt is found to be sharply dependent on the CO coverage, decreasing dramatically beyond 0.4 fractional coverage.

Low leakage Ru-strontium titanate-Ru metal-insulator-metal capacitors for sub-20?nm technology node in dynamic random access memory  

SciTech Connect

Improved metal-insulator-metal capacitor (MIMCAP) stacks with strontium titanate (STO) as dielectric sandwiched between Ru as top and bottom electrode are shown. The Ru/STO/Ru stack demonstrates clearly its potential to reach sub-20?nm technology nodes for dynamic random access memory. Downscaling of the equivalent oxide thickness, leakage current density (J{sub g}) of the MIMCAPs, and physical thickness of the STO have been realized by control of the Sr/Ti ratio and grain size using a heterogeneous TiO{sub 2}/STO based nanolaminate stack deposition and a two-step crystallization anneal. Replacement of TiN with Ru as both top and bottom electrodes reduces the amount of electrically active defects and is essential to achieve a low leakage current in the MIM capacitor.

Low-temperature Hall effect in substituted Sr2RuO4  

Science Journals Connector (OSTI)

We report the results of a study of the Hall effect and magnetoresistance in single crystals of Sr2RuO4 in which Sr2+ has been substituted by La3+ (Sr2?yLayRuO4) or Ru4+ by Ti4+ (Sr2Ru1?xTixO4). For undoped Sr2RuO4, the purity is so high that the strong-field Hall coefficient can be measured for fields above 4T. The conventional weak-field Hall coefficient as a function of doping shows a sharp jump and sign change at y?0.01 that is unrelated to either a sharp change in Fermi-surface topography or a magnetic instability. The implications of these results are discussed.

An understanding of hydrogen diffusion on metal surfaces is important, not just for its role in heterogeneous catalysis and hydrogen fuel cell technology, but also because it provides model systems where tunneling can be studied under well-defined conditions. Here we report helium spin-echo measurements of the atomic-scale motion of hydrogen on the Ru(0001) surface between 75 and 250 K. Quantum effects are evident at temperatures as high as 200 K, while below 120 K we observe a tunneling-dominated temperature independent jump rate of 1.9$\\times$10$^9$ s$^{-1}$, many orders of magnitude faster than previously seen. Quantum transition state theory calculations based on ab initio path-integral simulations reproduce the temperature dependence of the rate at higher temperatures and predict a crossover to tunneling-dominated diffusion at low temperatures, although the tunneling rate is under-estimated, highlighting the need for future experimental and theoretical studies of hydrogen diffusion on well-defined surfac...

Studies on the sulfur poisoning of Ru-RuO{sub x}/TiO{sub 2} catalyst for the adsorption and methanation of carbon monoxide  

SciTech Connect

The effects of sulfur poisoning on the chemisorption and on the methanation of carbon monoxide over Ru/TiO{sub 2} catalyst were investigated by FTIR spectroscopy and volumetric gas adsorption measurements. The CS{sub 2} molecules are {eta}` bonded to Ru sites through one of the sulfur atoms and decompose to the constituent elements on thermal activation. Each S atom may deactivate 3 to 10 metal sites even at low coverages, the effect being more pronounced on the chemisorption of hydrogen. The deposited sulfur (and possibly carbon also) sterically hinders the formation of certain multicarbonyl and monocarbonyl species (vCO in 2055-2140 cm{sup -1} region), which otherwise transform to methane via surface methylene groups in the presence of chemisorbed hydrogen and are found to play an important role in the low-temperature methanation activity of the studied catalyst. The Ru-CO species giving rise to lower frequency vibrational bands are affected to a lesser extent. The presence of sulfur also results in the development of some new CO binding states which are weak and are identified with the CO and S coadsorbed at Ru sites of different oxidation states or of varying crystallographic nature. The CO adsorbed in these states is not reactive to hydrogen. 45 refs., 9 figs., 1 tab.

Critical experiments on low-enriched uranium oxide systems with H/U = 2. 03  

SciTech Connect

Seven critical experiments were performed on a horizontal split table machine using 4.48% enriched /sup 235/U uranium oxide (U/sub 3/O/sub 8/). The oxide was compacted to a density of 4.68 g/cm/sup 3/ and placed in 152-mm cubical aluminum cans. Water was added to achieve an H/U atomic ratio of 2.03. Various arrays of oxide cans were distributed on each half of the split table and the separation between halves reduced until criticality occurred. The critical table separation varied from 4.3 mm to 29.3 mm. These experiments were performed in both plastic and concrete reflectors. The first five experiments required the addition of a high-enriched (approx. 93% /sup 235/U) metal driver to achieve criticality. Critical uranium driver masses ranged from 2.765 kg to 13.730 kg for 5 x 5 x 5 arrays of uranium oxide cans. In all five cases, the center can of the array was deleted to accommodate the driver. The uranium oxide mass was 1859.6 kg. Two additional experiments in the plastic reflector contained either 9.3-mm- or 24.3-mm-thick plastic moderator material between the oxide cans. These latter experiments did not require a driver to achieve criticality; and the uranium oxide mass was 723.9 kg for the configuration having the thinner interstitial moderator and 452.4 kg for the other.

Influence of Electron Doping on Magnetic Order in CeRu2Al10  

SciTech Connect

The effect of electron doping by the substitution of Rh for Ru on unconventional magnetic order in CeRu2Al10 was investigated via neutron powder diffraction. In Ce(Ru1 xRhx)2Al10 with x = 0.05, 0.12, and 0.2, reorientation of the ordered moment from the c-axis as in pure CeRu2Al10 to the a-axis takes place in all samples, while the ordering vector q 0; 1; 0 remains unchanged within this concentration range. The moment reorientation is accompanied by an increase in its size by a factor of 2.4, from = 0.43 B at x = 0 to = 1.06, 1.04, and 1.02 B for x = 0.05, 0.12, and 0.2, respectively. The continuous decrease in the N el temperature T0(TN), despite an abrupt increase in , underlines the strong anisotropy in the exchange interaction in CeRu2Al10 and the fact that this anisotropy is easily suppressed by electron doping. 1.

Charge transfer switching in photoexcited Ru(II) porphyrins: A time-resolved resonance Raman and spectroelectrochemical study  

SciTech Connect

The charge transfer (CT) excited states of Ru(II)OEP(Py){sub 2} and Ru(II)TPP(Py){sub 2} (TPP=tetraphenylporphyrin, OEP=octaethylporphyrin, and Py=pyridine) have been investigated by nanosecond time-resolved resonance Raman(TR{sup 3}) spectroscopy. The spectra reveal unexpected differences between the two species. The TR{sup 3} spectrum of [Ru(II)TPP(Py){sub 2}]{sup *} resembles the resonance Raman (RR) spectrum of the RuTPP(Py){sub 2} radical anion. Both spectra show strong enhancement of nontotally symmetric modes, resulting from a Jahn-Teller distortion due to the e{sub g}{sup *} orbital degeneracy. The band frequencies are slightly higher in the CT state than in the radical anion, reflecting the effect of the Ru(II) oxidation. Thus, the TR{sup 3} spectral features support a {sup 3}(d{pi},{pi}{sup *}) excited state assignment, with an electron transferred from Ru(II) to the porphyrin. In contrast, the TR3 spectrum [Ru(II)OEP(Py){sub 2}]{sup *} does not resemble the RR spectra of the Ru(II)OEP radical anion. Rather, it contains totally symmetric modes, at frequencies close to those of Ru(II)OEP(Py){sub 2}. In addition, bound pyridine modes appear at 1208 and 1603 cm{sup -1} in the TR{sup 3} spectrum and they shift upon pyridine perdeuteration. These characteristics imply electron transfer from Ru(II) to bound pyridine, instead of porphyrin, for the CT state of Ru(II)OEP(Py){sub 2}. 38 refs., 11 figs., 4 tabs.

Charged pion production in $^{96}_{44}$Ru+$^{96}_{44}$Ru collisions at 400A and 1528A MeV  

E-Print Network (OSTI)

We present transverse momentum and rapidity spectra of charged pions in central Ru + Ru collisions at 400$A$ and 1528$A$ MeV. The data exhibit enhanced production at low transverse momenta compared to the expectations from the thermal model that includes the decay of $\\Delta(1232)$-resonances and thermal pions. Modification of the $\\Delta$-spectral function and the Coulomb interaction are necessary to describe the detailed shape of the transverse momentum spectra. Within the framework of the thermal model, the freeze-out radii of pions are similar at both beam energies. The IQMD model reproduces the shapes of the transverse momentum and rapidity spectra of pions, but the predicted absolute yields are larger than in the measurements, especially at lower beam energy.

NiW and NiRu Bimetallic Catalysts for Ethylene Steam Reforming: Alternative Mechanisms for Sulfur Resistance  

SciTech Connect

Previous investigations of Ni-based catalysts for the steam reforming of hydrocarbons have indicated that the addition of a second metal can reduce the effects of sulfur poisoning. Two systems that have previously shown promise for such applications, NiW and NiRu, are considered here for the steam reforming of ethylene, a key component of biomass derived tars. Monometallic and bimetallic Al{sub 2}O{sub 3}-supported Ni and W catalysts were employed for ethylene steam reforming in the presence and absence of sulfur. The NiW catalysts were less active than Ni in the absence of sulfur, but were more active in the presence of 50 ppm H{sub 2}S. The mechanism for the W-induced improvements in sulfur resistance appears to be different from that for Ru in NiRu. To probe reasons for the sulfur resistance of NiRu, the adsorption of S and C{sub 2}H{sub 4} on several bimetallic NiRu alloy surfaces ranging from 11 to 33 % Ru was studied using density functional theory (DFT). The DFT studies reveal that sulfur adsorption is generally favored on hollow sites containing Ru. Ethylene preferentially adsorbs atop the Ru atom in all the NiRu (111) alloys investigated. By comparing trends across the various bimetallic models considered, sulfur adsorption was observed to be correlated with the density of occupied states near the Fermi level while C{sub 2}H{sub 4} adsorption was correlated with the number of unoccupied states in the d-band. The diverging mechanisms for S and C{sub 2}H{sub 4} adsorption allow for bimetallic surfaces such as NiRu that enhance ethylene binding without accompanying increases in sulfur binding energy. In contrast, bimetallics such as NiSn and NiW appear to decrease the affinity of the surface for both the reagent and the poison.

Lattice gas model for CO electrooxidation on Pt-Ru bimetallic surfaces  

SciTech Connect

The authors propose a lattice gas model for the carbon monoxide oxidation on platinum-ruthenium electrode surfaces. The kinetic model includes the main mechanistic bifunctional features as they are generally agreed upon in the literature. The CO stripping voltammetry is solved by dynamic Monte Carlo simulations. For a randomly dispersed alloy of Ru and Pt, the model gives a satisfactory semiquantitative agreement with the experimental CO stripping results of Gasteiger et al. [Journal of Physical Chemistry 1994, 98, 617]. It is shown how the bifunctional mechanism cannot operate if CO is not mobile on the surface, and a simple Tafel-type experiment with a low concentration of active Pt-Ru sites is suggested to check quantitatively the Co mobility rate. On a surface with large Ru islands, the overpotential for CO oxidation increases, and two CO stripping peaks may appear if the CO mobility is sufficiently low. A mean-field model of the system reproduces the DMC results for high CO mobility but breaks down for a system with large Ru islands and a comparatively low CO surface diffusion constant.

Conductive oxides RuO{sub x} as alternative electrode on high-{kappa} HfO{sub 2} gate dielectric have been fabricated by ultrahigh-vacuum sputtering and subsequently oxidized using oxygen plasma. The energy-band alignment for the RuO{sub x}/HfO{sub 2}/Si system and the oxidation-state dependence of barrier height for RuO{sub x} contacting to HfO{sub 2} dielectrics has been analyzed by x-ray photoemission spectroscopy. The valence- and conduction-band offsets of HfO{sub 2}/Si are determined to be 3.05{+-}0.1 and 1.48{+-}0.1 eV, respectively. The barrier heights for the RuO{sub x} contacting to HfO{sub 2} are oxidation-state dependent, in the range of 1.95-2.73 eV.

Enhanced oxygen evolution activity of IrO2 and RuO2 (100) surfaces  

SciTech Connect

The activities of the oxygen evolution reaction (OER) on IrO2 and RuO2 catalysts are among the highest known to date. However, the intrinsic OER activities of surfaces with defined crystallographic orientations are not well established experimentally. Here we report that the (100) surface of IrO2 and RuO2 is more active than the (110) surface that has been traditionally explored by density functional theory studies. The relation between the OER activity and density of coordinatively undersaturated metal sites exposed on each rutile crystallographic facet is discussed. The surface-orientation dependent activities can guide the design of high-surface-area catalysts with increased activity for electrolyzers, metal-air batteries, and photoelectrochemical water splitting applications.

Metal-and hydrogen-bonding competition during water absorption on Pd(111) and Ru(0001)  

SciTech Connect

The initial stages of water adsorption on the Pd(111) and Ru(0001) surfaces have been investigated experimentally by Scanning Tunneling Microscopy in the temperature range between 40 K and 130 K, and theoretically with Density Functional Theory (DFT) total energy calculations and STM image simulations. Below 125 K water dissociation does not occur at any appreciable rate and only molecular films are formed. Film growth starts by the formation of flat hexamer clusters where the molecules bind to the metal substrate through the O-lone pair while making H-bonds with neighboring molecules. As coverage increases, larger networks of linked hexagons are formed with a honeycomb structure, which requires a fraction of the water molecules to have their molecular plane perpendicular to the metal surface with reduced water-metal interaction. Energy minimization favors the growth of networks with limited width. As additional water molecules adsorb on the surface they attach to the periphery of existing islands, where they interact only weakly with the metal substrate. These molecules hop along the periphery of the clusters at intermediate temperatures. At higher temperatures they bind to the metal to continue the honeycomb growth. The water-Ru interaction is significantly stronger than the water-Pd interaction, which is consistent with the greater degree of hydrogen-bonded network formation and reduced water-metal bonding observed on Pd relative to Ru.

High-spin levels of the neutron-rich {sup 114}Ru have been investigated by measuring the prompt {gamma} rays in the spontaneous fission of {sup 252}Cf. The ground-state band and one-phonon {gamma}-vibrational band have been extended up to 14{sup +} and 9{sup +}, respectively. Two levels are proposed as the members of a two-phonon {gamma}-vibrational band. A back bending (band crossing) has been observed in the ground-state band at ({h_bar}/2{pi}){omega}{approx_equal} 0.40 MeV. Using the triaxial deformation parameters, the cranked shell model calculations indicate that this back bending in {sup 114}Ru should originate from the alignment of a pair of h{sub 11/2} neutrons. Triaxial projected shell model calculations for the {gamma}-vibrational band structures of {sup 114}Ru are in good agreement with the experimental data. However, when using the oblate deformation parameters, both of the above-calculated results are not in agreement with the experimental data.

Water adsorption on O(2x2)/Ru(0001) from STM experiments andfirst-principles calculations  

SciTech Connect

We present a combined theoretical and experimental study of water adsorption on Ru(0001) pre-covered with 0.25 monolayers (ML) of oxygen forming a (2 x 2) structure. Several structures were analyzed by means of Density Functional Theory calculations for which STM simulations were performed and compared with experimental data. Up to 0.25 monolayers the molecules bind to the exposed Ru atoms of the 2 x 2 unit cell via the lone pair orbitals. The molecular plane is almost parallel to the surface with its H atoms pointing towards the chemisorbed O atoms of the 2 x 2 unit cell forming hydrogen bonds. The existence of these additional hydrogen bonds increases the adsorption energy of the water molecule to approximately 616 meV, which is {approx}220 meV more stable than on the clean Ru(0001) surface with a similar configuration. The binding energy shows only a weak dependence on water coverage, with a shallow minimum for a row structure at 0.125 ML. This is consistent with the STM experiments that show a tendency of the molecules to form linear rows at intermediate coverage. Our calculations also suggest the possible formation of water dimers near 0.25 ML.

Water Induced Surface Reconstruction of the Oxygen (2x1) covered Ru(0001)  

SciTech Connect

Low temperature scanning tunneling microscopy (STM) and density functional theory (DFT) were used to study the adsorption of water on a Ru(0001) surface covered with half monolayer of oxygen. The oxygen atoms occupy hcp sites in an ordered structure with (2x1) periodicity. DFT predicts that water is weakly bound to the unmodified surface, 86 meV compared to the ~;;200 meV water-water H-bond. Instead, we found that water adsorption causes a shift of half of the oxygen atoms from hcp sites to fcc sites, creating a honeycomb structure where water molecules bind strongly to the exposed Ru atoms. The energy cost of reconstructing the oxygen overlayer, around 230 meV per displaced oxygen atom, is more than compensated by the larger adsorption energy of water on the newly exposed Ru atoms. Water forms hydrogen bonds with the fcc O atoms in a (4x2) superstructure due to alternating orientations of the molecules. Heating to 185 K results in the complete desorption of the water layer, leaving behind the oxygen honeycomb structure, which is metastable relative to the original (2x1). This stable structure is not recovered until after heating to temperatures close to 260K.

Manipulating Magnetism: Ru-2(5+) Paddlewheels Devoid of Axial Interactions  

SciTech Connect

Variable-temperature magnetic and structural data of two pairs of diruthenium isomers, one pair having an axial ligand and the formula Ru-2(DArF)(4)Cl (where DArF is the anion of a diarylformamidine isomer and Ar = p-anisyl or m-anisyl) and the other one being essentially identical but devoid of axial ligands and having the formula [Ru-2(DArF)(4)]BF4, show that the axial ligand has a significant effect on the electronic structure of the diruthenium unit. Variable temperature crystallographic and magnetic data as well as density functional theory calculations unequivocally demonstrate the occurrence of pi interactions between the p orbitals of the chlorine ligand and the pi* orbitals in the Ru-2(5+) units. The magnetic and structural data are consistent with the existence of combined ligand sigma/metal sigma and ligand p pi/metal-d pi interactions. Electron paramagnetic resonance data show unambiguously that the unpaired electrons are in metal-based molecular orbitals.

Thermal response of Ru electrodes in contact with SiO{sub 2} and Hf-based high-k gate dielectrics  

SciTech Connect

A systematic experimental evaluation of the thermal stability of Ru metal gate electrodes in direct contact with SiO{sub 2} and Hf-based dielectric layers was performed and correlated with electrical device measurements. The distinctly different interfacial reactions in the Ru/SiO{sub 2}, Ru/HfO{sub 2}, and Ru/HfSiO{sub x} film systems were observed through cross-sectional high-resolution transmission electron microscopy, high angle annular dark field scanning transmission electron microscopy with electron-energy-loss spectra, and energy dispersive x-ray spectra analysis. Ru interacted with SiO{sub 2}, but remained stable on HfO{sub 2} at 1000 deg. C. The onset of Ru/SiO{sub 2} interfacial interactions is identified via silicon substrate pitting possibly from Ru diffusion into the dielectric in samples exposed to a 900 deg. C/10-s anneal. The dependence of capacitor device degradation with decreasing SiO{sub 2} thickness suggests Ru diffuses through SiO{sub 2}, followed by an abrupt, rapid, nonuniform interaction of ruthenium silicide as Ru contacts the Si substrate. Local interdiffusion detected on Ru/HfSiO{sub x} samples may be due to phase separation of HfSiO{sub x} into HfO{sub 2} grains within a SiO{sub 2} matrix, suggesting that SiO{sub 2} provides a diffusion pathway for Ru. Detailed evidence consistent with a dual reaction mechanism for the Ru/SiO{sub 2} system at 1000 deg. C is presented.

Features of the band structure and conduction mechanisms in the n-HfNiSn semiconductor heavily doped with Ru  

SciTech Connect

The crystal and electronic structure and energy and kinetic properties of the n-HfNiSn semiconductor heavily doped with a Ru acceptor impurity are investigated in the temperature and Ru concentration ranges T = 80400 K and N{sub A}{sup Ru} ? 9.5 10{sup 19}?5.7 10{sup 20} cm{sup ?3} (x = 00.03), respectively. The mechanism of structural-defect generation is established, which changes the band gap and degree of compensation of the semiconductor and consists in the simultaneous concentration reduction and elimination of donor structural defects by means of the displacement of ?1% of Ni atoms from the Hf (4a) positions, the generation of acceptor structural defects upon the substitution of Ru atoms for Ni atoms in the 4c positions, and the generation of donor defects in the form of vacancies in the Sn (4b) positions. The calculated electronic structure of HfNi{sub 1?x}Ru{sub x}Sn is consistent with the experiment. The results obtained are discussed within the Shklovsky-Efros model for a heavily doped and compensated semiconductor.

Electronic and elastic properties of Sr2RuO4 with pressure effects by first principles calculation  

Science Journals Connector (OSTI)

Abstract In this work, electronic and elastic properties along with the pressure effects of the unconventional superconductor Sr2RuO4 are investigated by first principles calculation. Band structure calculation reveals that Sr2RuO4 is a weak metal. The characteristic of the band structure has also been analyzed. The calculated elastic constants reproduce the experimental data well. Analyses disclose that Sr2RuO4 is mechanically stable but anisotropic. The calculated Debye temperature 475.0K is in good agreement with the experimental results. Surveys of the pressure effect on the lattice constants reveal that the a axis is less compressible than the c axis, as found in the experiment. Further investigations illustrate that Sr2RuO4 is mechanically stable up to 50GPa till the elastic constant C44 fails to meet the mechanical stability criterion. The pressure-dependent elastic parameters are also investigated to know their behaviors under pressure. In addition, the bonding properties of Sr2RuO4 at 0GPa and 50GPa are analyzed to explain its elastic behavior under pressure.

Ultrafast Magnetization Dynamics of SrRuO3 Thin Films  

SciTech Connect

Itinerant ferromagnet SrRuO3 has drawn interest from physicists due to its unusual transport and magnetic properties as well as from engineers due to its low resistivity and good lattice-matching to other oxide materials. The exact electronic structure remains a mystery, as well as details of the interactions between magnetic and electron transport properties. This thesis describes the use of time-resolved magneto-optical Kerr spectroscopy to study the ferromagnetic resonance of SrRuO3 thin films, where the ferromagnetic resonance is initiated by a sudden change in the easy axis direction in response to a pump pulse. The rotation of the easy axis is induced by laser heating, taking advantage of a temperature-dependent easy axis direction in SrRuO3 thin films. By measuring the change in temperature of the magnetic system in response to the laser pulse, we find that the specific heat is dominated by magnons up to unusually high temperature, ~;;100 K, and thermal diffusion is limited by a boundary resistance between the film and the substrate that is not consistent with standard phonon reflection and scattering models. We observe a high FMR frequency, 250 GHz, and large Gilbert damping parameter, alpha ~;; 1, consistent with strong spin-orbit coupling. We observe a time-dependent change in the easy axis direction on a ps time-scale, and we find that parameters associated with the change in easy axis, as well as the damping parameter, have a non-monotonic temperature dependence similar to that observed in anomalous Hall measurements.

Crystal structure and magnetic properties of Pr- and Ti-substituted La{sub 2}RuO{sub 5}  

SciTech Connect

Highlights: Synthesis of polycrystalline Pr and Ti co-substituted La{sub 2}RuO{sub 5} with soft chemistry. Investigation of structureproperty relationship of the dimerization transition. Additive behavior of structural changes caused by either Pr or Ti substitution. Additive behavior of ht-phase paramagnetism of Pr and Ti substitution. Additive influence of Pr and Ti substitution on the dimerization transition. - Abstract: Polycrystalline samples of Pr- and Ti-substituted La{sub 2}RuO{sub 5} were prepared applying a soft-chemistry route based on the thermal decomposition of citrate-stabilized precursors. The simultaneous substitution on the La-sites by Pr and on the Ru-sites by Ti results in samples of the composition La{sub 2?x}Pr{sub x}Ru{sub 1?y}Ti{sub y}O{sub 5} with 0 ? x ? 0.75 and 0 ? y ? 0.4. The crystal structures of these compounds were analyzed by Rietveld refinement of powder X-ray diffraction patterns. For pure La{sub 2}RuO{sub 5} a structural transition from a monoclinic room-temperature modification to a triclinic low-temperature structure was found at 161 K. This structural change is linked to a low-temperature long-range ordered spin-singlet ground state formed by Ru{sup 4+} spin-moments. Both the structural transition and the formation of the singlet ground state become progressively suppressed with higher Ti contents, while the Pr substitution has only a minor influence on the dimerization. The behavior of the CurieWeiss temperatures can be explained assuming two almost independent magnetic sublattices corresponding to the ruthenium and the rare-earth ions, respectively. For all investigated properties, i.e. crystal structure, magnetic susceptibilities, and dimerization temperature T{sub d}, a completely additive behavior of the effects of Pr-substitution and Ti-substitution is observed.

Spin-gap opening accompanied by a strong magnetoelastic response in the S=1 magnetic dimer system Ba3BiRu2O9  

Science Journals Connector (OSTI)

Neutron diffraction, magnetization, resistivity, and heat-capacity measurements on the 6H-perovskite Ba3BiRu2O9 reveal simultaneous magnetic and structural dimerization driven by strong magnetoelastic coupling. An isostructural but strongly displacive first-order transition on cooling through T*=176 K is associated with a change in the nature of direct RuRu bonds within Ru2O9 face-sharing octahedra. Above T*, Ba3BiRu2O9 is an S=1 magnetic dimer system with intradimer exchange interactions J0/kB=320 K and interdimer exchange interactions J?/kB=?160 K. Below T*, a spin-gapped state emerges with ??220 K. Ab initio calculations confirm antiferromagnetic exchange within dimers, but the transition is not accompanied by long-range magnetic order.

The structure of mixed H2O-OH monolayer films on Ru(0001)  

SciTech Connect

Scanning tunneling microscopy (STM) and x-ray absorption spectroscopy (XAS) have been used to study the structures produced by water on Ru(0001) at temperatures above 140 K. It was found that while undissociated water layers are metastable below 140 K, heating above this temperature produces drastic transformations whereby a fraction of the water molecules partially dissociate and form mixed H{sub 2}O-OH structures. XPS and XAS revealed the presence of hydroxyl groups with their O-H bond essentially parallel to the surface. STM images show that the mixed H{sub 2}O-OH structures consist of long narrow stripes aligned with the three crystallographic directions perpendicular to the close-packed atomic rows of the Ru(0001) substrate. The internal structure of the stripes is a honeycomb network of H-bonded water and hydroxyl species. We found that the metastable low temperature molecular phase can also be converted to a mixed H{sub 2}O-OH phase through excitation by the tunneling electrons when their energy is 0.5 eV or higher above the Fermi level. Structural models based on the STM images were used for Density Functional Theory optimizations of the stripe geometry. The optimized geometry was then utilized to calculate STM images for comparison with the experiment.

Coadsorption of hydrogen and ethylene, and carbon monoxide and ethylene on the Ru(001) surface  

SciTech Connect

A detailed investigation of the coadsorption of ethylene with both preadsorbed hydrogen and preadsorbed carbon monoxide on the Ru(001) surface is reported here. Both preadsorbed hydrogen and carbon monoxide reduce the saturation coverage of subsequently chemisorbed ethylene. The coadsorption of hydrogen with ethylene results in detectable hydrogenation of ethylene to ethane below 250 K, whereas no self-hydrogenation of ethylene to ethane is observed. High-resolution electron energy loss spectra show that ethylene coadsorbed with either hydrogen or carbon monoxide decomposes to ethylidyne (CCH/sub 3/) and acetylide (CCH), as it does on the clean surface. Carbon monoxide preadsorption enhances the stability of the ethylidyne such that it decomposes at approximately 420 K, rather than 355 K as on the initially clean Ru(001) surface. Preadsorbed carbon monoxide also reduces the ratio of ethylidyne to acetylide that is formed from ethylene, compared to the ratio observed from an equivalent coverage of ethylene on the clean surface; hydrogen preadsorption, on the other hand, increases this ratio.

Hydrogen production by methane steam reforming over Ru supported on NiMgAl mixed oxides prepared via hydrotalcite route  

Science Journals Connector (OSTI)

Abstract Catalytic performance of Ru/NixMg6?xAl2 800800 mixed oxides, with x=2, 4 and 6, x being the molar ratio, towards Methane Steam Reforming, was studied. NixMg6?xAl2 800 oxide, used as support, was prepared via hydrotalcite route. It was thermally stabilized at 800C, impregnated with 0.5wt.% ruthenium using ruthenium (III) nitrosyl nitrate Ru(NO) (NO3)3 precursor and then calcined again at 800C under an air flow. Ruthenium impregnation significantly enhanced the reactivity of the oxides in Methane Steam Reforming. In fact, it was found, that even with a low ruthenium content (0.5wt.%), ruthenium oxide particles are formed but are well dispersed over the surface of the oxide NixMg6?xAl2 800. Ru/Ni6Al2 800800 showed better catalytic performances, towards Methane Steam Reforming, than ruthenium impregnated on the two other supports. Indeed, nickel content is higher in Ni6Al2 800 than in the other studied supports and therefore the probability of NiRu interaction should be greater and consequently catalytic performances could be improved.

Chemical Effect of Dry and Wet Cleaning of the Ru Protective Layer of the Extreme ultraviolet (EUV) Lithography Reflector  

SciTech Connect

The authors report the chemical influence of cleaning of the Ru capping layer on the extreme ultraviolet (EUV) reflector surface. The cleaning of EUV reflector to remove the contamination particles has two requirements: to prevent corrosion and etching of the reflector surface and to maintain the reflectivity functionality of the reflector after the corrosive cleaning processes. Two main approaches for EUV reflector cleaning, wet chemical treatments [sulfuric acid and hydrogen peroxide mixture (SPM), ozonated water, and ozonated hydrogen peroxide] and dry cleaning (oxygen plasma and UV/ozone treatment), were tested. The changes in surface morphology and roughness were characterized using scanning electron microscopy and atomic force microscopy, while the surface etching and change of oxidation states were probed with x-ray photoelectron spectroscopy. Significant surface oxidation of the Ru capping layer was observed after oxygen plasma and UV/ozone treatment, while the oxidation is unnoticeable after SPM treatment. Based on these surface studies, the authors found that SPM treatment exhibits the minimal corrosive interactions with Ru capping layer. They address the molecular mechanism of corrosive gas and liquid-phase chemical interaction with the surface of Ru capping layer on the EUV reflector.

Electronic structure of the Nowotny chimney-ladder silicide Ru{sub 2}Si{sub 3}  

SciTech Connect

We report {ital ab initio} calculations for the electronic structure of the Nowotny chimney-ladder silicide Ru{sub 2}Si{sub 3} in the orthorhombic low-temperature phase. We find Ru{sub 2}Si{sub 3} to be a semiconductor with a direct band gap of about 0.45 eV. Since this gap is a p-d gap, the oscillator strength for a direct transition is expected to be of sizable magnitude. Also, the calculated effective masses of hole and electron states suggest that Ru{sub 2}Si{sub 3} is a very promising material for various applications in semiconductor technology. The electronic structure is controlled by the hybridization of Si p states with Ru d states and shows similarities to the group-IV transition-metal disilicides (CrSi{sub 2}, MoSi{sub 2}, WSi{sub 2}) and to transition-metal-rich silicides. The calculations are based on the density-functional theory in local-density approximation and are performed by means of the full-potential linearized-augmented-plane-wave method. {copyright} {ital 1997} {ital The American Physical Society}

First-principles study of the role of solvent in the dissociation of water over a Pt-Ru alloy  

Science Journals Connector (OSTI)

Self-consistent gradient-corrected periodic density functional theoretical calculations are used to examine the effects of an aqueous environment on the dissociation of water over a Pt-Ru alloy. This reaction is thought to be one of the rate-limiting steps in oxidative removal of CO from the anode surface of both the direct methanol and reformate fuel cells. The reaction leads to the formation of surface hydroxyl (OH) intermediates that can subsequently oxidize adsorbed CO into CO2. We examine the energetics and mechanism for the dissociation of water over Pt66Ru33(111) in the presence of 23 water molecules (per 615 3 unit cell volume) that act as a solution phase and in the absence of solution (vapor phase). The reaction is endothermic by +53 kJ/mol and has an activation barrier of +105 kJ/mol when carried out in the vapor phase, but was found to be much less endothermic (+26 kJ/mol) and has a significantly lower activation barrier (+27 kJ/mol) when carried out in solution. In the vapor phase, the reaction occurs homolytically whereby the dissociation is activated by insertion of a Ru atom into the O-H bond of water. The products formed are adsorbed hydroxyl and hydrogen intermediates. In contrast, in solution, the dissociation occurs via a heterolytic path whereby the solvent molecules are directly involved in activating the O-H bond. The reaction leads to the formation of a hydroxyl intermediate that is bound to the alloy surface and a proton that is released into the solution phase. Ab initio molecular dynamics simulations were performed at 300 K to establish the sequence of elementary steps that can occur. The simulations show that water dissociates over Ru and that the hydroxyl intermediate that first forms over Ru rapidly diffuses along the metal surface, migrating over Pt as well as Ru sites. We believe that this evidence shows that diffusion occurs as the result of the proton transfer between the coadsorbed water and hydroxyl intermediates in an aqueous environment. This could have important consequences for CO oxidation in PEM fuel cells whereby the diffusion of CO and/or OH intermediates is important for the reaction at the edge of the Pt/Ru boundaries. The work reported herein applies at open-circuit potentials, but may also be appropriate at other potentials as well.

Up-Hill Electron Transfer in Pentaammineruthenium(III)-Modified Up-Hill Electron Transfer in Pentaammineruthenium(III)-Modified Ferrocytochrome c: Rates, Thermodynamics, and the Mediating Role of the Ruthenium Moiety Ji Sun, James F. Wishart, and Stephan S. Isied Inorg. Chem. 34, 3998-4000 (1995) Abstract: At moderate to high ionic strengths (>0.1 M), Co(oxalate)33- oxidizes native cytochrome c very slowly, however it undergoes a rapid reaction with pendant ruthenium complexes covalently attached to the surface of the protein. Under these conditions, the rate of the thermodynamically unfavorable (up-hill) FeII-to-RuIII electron transfer process in pentaammineruthenium-modified horse-heart cytochrome c can be revealed using sufficiently high Co(oxalate) 33- concentrations. Rate measurements performed over a wide range of CoIII concentrations confirm the proposed

Chemical reactions of water molecules on Ru(0001) induced by selective excitation of vibrational modes  

SciTech Connect

Tunneling electrons in a scanning tunneling microscope were used to excite specific vibrational quantum states of adsorbed water and hydroxyl molecules on a Ru(0 0 0 1) surface. The excited molecules relaxed by transfer of energy to lower energy modes, resulting in diffusion, dissociation, desorption, and surface-tip transfer processes. Diffusion of H{sub 2}O molecules could be induced by excitation of the O-H stretch vibration mode at 445 meV. Isolated molecules required excitation of one single quantum while molecules bonded to a C atom required at least two quanta. Dissociation of single H{sub 2}O molecules into H and OH required electron energies of 1 eV or higher while dissociation of OH required at least 2 eV electrons. In contrast, water molecules forming part of a cluster could be dissociated with electron energies of 0.5 eV.

Two neutrino double ? decay of 100Mo to the 2+ excited state of 100Ru  

Science Journals Connector (OSTI)

The two neutrino double ? decay of 100Mo for 0+?2+ transition is studied in the projected Hartree-Fock-Bogoliubov framework. In our earlier work, the reliability of the intrinsic wave functions has been established for 100Mo and 100Ru by obtaining an overall agreement between the available experimental data and theoretically calculated results for yrast spectra, reduced transition probabilities B(E2:0+?2+), quadrupole moments Q(2+), gyromagnetic factors g(2+), and double Gamow-Teller matrix element for 0+?0+ transition. In the present work, the half-life for 0+?2+ transition T1/22?(0+?2+) has been calculated using the same set of intrinsic wave functions.

The Effects of Oxygen Plasma on the Chemical Composition and Morphology of the Ru Capping Layer of the Extreme Ultraviolet (EUV) Mask Blanks  

SciTech Connect

Contamination removal from extreme ultraviolet (EUV) mask surfaces is one of the most important aspects to improve reliability for the next generation of EUV lithography. We report chemical and morphological changes of the ruthenium (Ru) mask surface after oxygen plasma treatment using surface sensitive analytical methods: X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and transmission electron microscopy (TEM). Chemical analysis of the EUV masks shows an increase in the subsurface oxygen concentration, Ru oxidation and surface roughness. XPS spectra at various photoelectron takeoff angles suggest that the EUV mask surface was covered with chemisorbed oxygen after oxygen plasma treatment. It is proposed that the Kirkendall effect is the most plausible mechanism that explains the Ru surface oxidation. The etching rate of the Ru capping layer by oxygen plasma was estimated to be 1.5 {+-} 0.2 {angstrom}/min, based on TEM cross sectional analysis.

THE PROGENITOR OF SN 2011ja: CLUES FROM CIRCUMSTELLAR INTERACTION  

SciTech Connect

Massive stars, possibly red supergiants, which retain extended hydrogen envelopes until core collapse, produce Type II plateau (IIP) supernovae. The ejecta from these explosions shocks the circumstellar matter originating from the mass loss of the progenitor during the final phases of its life. This interaction accelerates particles to relativistic energies which then lose energy via synchrotron radiation in the shock-amplified magnetic fields and inverse Compton scattering against optical photons from the supernova. These processes produce different signatures in the radio and X-ray parts of the electromagnetic spectrum. Observed together, they allow us to break the degeneracy between shock acceleration and magnetic field amplification. In this work, we use X-rays observations from the Chandra and radio observations from the Australia Telescope Compact Array to study the relative importance of processes which accelerate particles and those which amplify magnetic fields in producing the non-thermal radiation from SN 2011ja. We use radio observations to constrain the explosion date. Multiple Chandra observations allow us to probe the history of variable mass loss from the progenitor. The ejecta expands into a low-density bubble followed by interaction with a higher density wind from a red supergiant consistent with M{sub ZAMS} {approx}> 12 M{sub Sun }. Our results suggest that a fraction of Type IIP supernovae may interact with circumstellar media set up by non-steady winds.

CO Coverage/Oxidation Correlated with PtRu Electroscatalyst Particle Morphology in 0.3 M Methanol by In Situ XAS  

SciTech Connect

In situ X-ray absorption spectroscopy (XAS) measurements, including both X-ray absorption near edge spectroscopy (XANES) and extended X-ray absorption fine structure (EXAFS) at the Pt L{sub 3} and Ru K edges, were carried out on three different carbon-supported PtRu electrocatalysts in an electrochemical cell in 1 M HClO{sub 4} with 0.3 M methanol. The CO and OH adsorbate coverage on Pt and Ru were determined as a function of the applied potential via the novel delta XANES technique, and the particle morphology was determined from the EXAFS and a modeling technique. Both the bifunctional and direct CO oxidation mechanisms, the latter enhanced by electronic ligand effects, were evident for all three electrocatalysts; however, the dominant mechanism depended critically on the particle size and morphology. Both the Ru island size and overall cluster size had a very large effect on the CO oxidation mechanism and activation of water, with the bifunctional mechanism dominating for more monodispersed Ru islands, and the direct surface ligand effect dominating in the presence of larger Ru islands.

Photophysical Studies of Ru(II)tris(2,2;#8242;-bipyridine) Confined within a Zn(II)?Trimesic Acid Polyhedral Metal?Organic Framework  

SciTech Connect

The ability to confine photoactive catalysts within metal-organic framework (MOF) materials affords the opportunity to expand the functional diversity of these materials into solar based applications. Here, the confinement of Ru(II)tris(2,2'-bipyridine) (RuBpy) by a MOF material derived from Zn(II) ions and trimesic acid (hereafter, USF2) is examined. Although the encapsulated RuBpy could not be crystallographically resolved within the MOF framework, the photophysical properties of the complex are characteristic of confinement including extended triplet metal-to-ligand ({sup 3}MLCT) lifetime ({tau}{sub ethanol} = 614 ns and {tau}{sub USF2} = 1.2 {micro}s at 25 C) and a slight hypsochromic shift in the steady-state emission spectrum relative to RuBpy in ethanol. The extended lifetime is attributed to a deactivation of a nonradiative {sup 3}dd that is antibonding with respect to the Ru(II)-bipyridine due to a confined molecular environment. These results represent one of the first examples of RuBpy encapsulation and photophysical characterization within a polyhedral MOF material.

/sup 13/C magic angle spinning NMR study of CO adsorption on Ru-exchanged zeolite Y  

SciTech Connect

Three types of adsorbed carbon monoxide are observed on Ru-Y zeolite by /sup 13/C magic angle spinning NMR: linear, bridged, and dicarbonyl CO. Samples exposed to CO at room temperature exhibit only linear and dicarbonyl species. At higher adsorption temperature bridged species are formed and a relative increase in dicarbonyl adsorption is observed. A smaller percentage of linear species is produced at high temperature. The electronic environments of linearly bonded CO are more diverse than those of bridging and dicarbonyl moieties. CO/sub 2/ is formed over Ru-Y zeolite upon initial exposure of the catalyst to CO at room temperature, apparently through reaction with unreduced metal oxide. 20 references, 2 figures, 1 table.

Impact of IrRu Oxygen Evolution Reaction Catalysts on Pt Nanostructured Thin Films under Start-Up/Shutdown Cycling  

SciTech Connect

Electron microscopy and X-ray photoelectron spectroscopy (XPS) methods have been utilized to study the role of oxygen evolution reaction (OER) catalysts in mitigating degradation arising from start-up/shutdown events. Pt nanostructured thin films (NSTF) were coated with a Ru0.1Ir0.9 OER catalyst at loadings ranging from 1 to 10 g/cm2 and submitted to 5,000 potential cycles within a membrane electrode assembly. Analysis of the as-deposited catalyst showed that Ir and Ru coating is primarily metallic, and further evidence is provided to support the previously reported interaction between Ru and the perylene-red support. Aberration-corrected scanning transmission electron microscopy and energy dispersive X-ray spectroscopy were used to observe the impact of the OER catalysts on Pt dissolution and migration through the membrane. Elemental mapping showed a high percentage of the Ir catalyst was maintained on the NSTF whisker surfaces following testing. The presence of the OER catalysts greatly reduced the smoothing of the Pt NSTF whiskers, which has been correlated with Pt dissolution and losses in electrochemically active surface area. The dissolution of both Ir and Pt led to the formation of IrPt nanoparticle clusters in the membrane close to the cathode, as well as the formation of a Pt band deeper in the membrane.

Aqueous-phase selective aerobic oxidation of 5-hydroxymethylfurfural on Ru/C in the presence of base  

Science Journals Connector (OSTI)

Abstract The aerobic oxidation of 5-hydroxymethylfurfural (HMF) was performed on an activated carbon-supported ruthenium (Ru/C) catalyst in water. The presence of Mg-Al hydrotalcite (HT, Mg/Al molar ratio = 3/1) as a base afforded higher selective oxidation of HMF to 5-formyl-2-furancarboxylic acid (FFCA) and 2,5-furandicarboxylic acid (FDCA) than with the bases MgO, Ca(OH)2 and NaOH owing to its appropriate strength of basicity. X-ray photoelectron spectroscopy characterization confirmed that metallic Ru0 species were the active sites for HMF oxidation. Isotopic tracer experiments conducted with 18O2 and 16O2 indicated that H2O rather than O2 provided the oxygen atom for the oxidation of HMF to FFCA and FDCA via hydration of the formyl group. These results and kinetic studies of the oxidation of HMF and 2,5-diformylfuran (DFF) led to the proposition that the aerobic oxidation of HMF to FFCA follows a Langmuir-Hinshelwood mechanism. The oxidation involved dissociative adsorption of HMF and O2 to form adsorbed alcoholate and atomic oxygen species followed by kinetically relevant abstraction of ?-H from the alcoholate species via the atomic oxygen species to adsorbed DFF species on the Ru surface, which then underwent hydration and oxidation to FFCA under basic conditions.

EXAFS study on the morphology change of Ru catalyst by CO adsorption  

SciTech Connect

Great attention has recently been paid to the reconstruction of clean metal surface upon adsorption. Then a question naturally arise what happens to the small metal clusters in supported catalyst upon adsorption, which is the first step of catalytic reaction. Surface spectroscopic techniques like LEED are not available for small particles on the surface of supports, and mainly infrared absorption spectroscopy has provided information, rather indirectly, through the number of observed vibrations and the frequency shifts of adsorbed species such as CO. Recently Van't Blik et al. reported in a series of papers direct evidence of a structural change of Rh clusters supported in Al/sub 2/O/sub 3/ upon CO adsorption. They observed a drastic change in EXAFS (extended X-ray absorption fine structure) by the admission of CO. It was concluded that this change was caused by the disruption of the metal-metal bond, resulting in formation of Rh(CO)/sub 2/ species. As far as the authors know, this is the only example of straightforward evidence of morphology changes caused by adsorption, and it is not certain whether or not this phenomenon is general. In this communication they present another example of the morphology change upon adsorption for Ru supported on ..gamma..-Al/sub 2/O/sub 3/ and show this phenomenon is not limited to Rh.

Elastic and chemical contributions to the stability of magnetic surface alloys on Ru(0001)  

Science Journals Connector (OSTI)

We have used density-functional theory to study the miscibility and magnetic properties of surface alloys. Our systems consist of a single pseudomorphic layer of MxN1?x on the Ru(0001) surface, where M=Fe or Co, and N=Pt, Au, Ag, Cd, or Pb. Several of the combinations studied by us display a preference for atomically mixed configurations over phase-segregated forms. We have also performed further ab initio calculations to obtain the parameters describing the elastic interactions between atoms in the alloy layer, including the effective atomic sizes at the surface. We find that while elastic interactions favor alloying for all the systems considered by us, in some cases chemical interactions disfavor atomic mixing. We show that a simple criterion (analogous to the Hume-Rothery first law for bulk alloys) need not necessarily work for strain-stabilized surface alloys because of the presence of additional elastic contributions to the alloy heat of formation that will tend to oppose phase segregation. We find that magnetic moments are significantly enhanced with respect to the bulk elements.

Diruthenium Tetracarbonate Trianion, [RuII/III(O2 CO)4 3- Based Molecule Based Magnets: Three-Dmensional Network Structure and Two Dimensional Magnetic Ordering  

SciTech Connect

HxK1-xMII[Ru2(CO3)4](H2O)y(MeOH)z (M = Mn, Fe, Co, Ni, Mg) were synthesized from the reaction of MII and K3[Ru2(CO3)4] in water and are isomorphous with an orthorhombic three-dimensional network structures based on e3-CO32- linkages to Ru2 moieties forming layers and also to trans-MII(OH2)4 sites forming linked chains that connect the layers. They, as well as non-isomorphous M = Cu, magnetically order as canted ferrimagnets with Tc = 4.4 {+-} 1.0 K. The presence of S = 0 MII = Mg(II) has essentially no effect on Tc suggesting that the main magnetic pathway does not occur the through MII-based chains, but only via Ru2{center_dot}...Ru2 linkages that reside in layers. This is a rare example of a magnet based upon a second row transition metal.

Commensurate-incommensurate magnetic phase transition in the Fe-doped bilayer ruthenate Ca3Ru2O7  

Science Journals Connector (OSTI)

Neutron diffraction studies have revealed an uncommon commensurate-incommensurate magnetic phase transition with decreasing temperature in the (?5%) Fe-doped bilayer ruthenate Ca3(Ru,Fe)2O7. An incommensurate phase formed of a cycloidal spiral spin structure coexists with a commensurate one below the phase transition at 42 K and persists down to the lowest temperature, accompanied by higher-order magnetic satellite peaks which indicate the formation of a magnetic soliton lattice. We ascribe these findings to the competing magnetic interactions in this system. This study demonstrates an effective approach to tune novel magnetic and electronic properties of ruthenates via 3d magnetic transition-metal substitution.

Exotic magnetism on the quasi-FCC lattices of the d3 double perovskites La2NaB'O6 (B' = Ru, Os)  

SciTech Connect

We find evidence for long-range and short-range ($\\zeta$~$=$~70~\\AA~at 4~K) incommensurate magnetic order on the quasi-face-centered-cubic (FCC) lattices of the monoclinic double perovskites La$_2$NaRuO$_6$ and La$_2$NaOsO$_6$ respectively. Incommensurate magnetic order on the FCC lattice has not been predicted by mean field theory, but may arise via a delicate balance of inequivalent nearest neighbour and next nearest neighbour exchange interactions. In the Ru system with long-range order, inelastic neutron scattering also reveals a spin gap $\\Delta$~$\\sim$~2.75~meV. Magnetic anisotropy is generally minimized in the more familiar octahedrally-coordinated $3d^3$ systems, so the large gap observed for La$_2$NaRuO$_6$ may result from the significantly enhanced value of spin-orbit coupling in this $4d^3$ material.

Adsorption of water on O(2x2)/Ru(0001): thermal stability and inhibition of dissociation by H2O-O bonding  

SciTech Connect

The effect of preadsorbed oxygen on the subsequent adsorption and reactions of water on Ru(0001) has been studied using low temperature scanning tunneling microscopy and DFT calculations. Experiments were carried out for O coverages close to 0.25 ML. It was found that no dissociation of water takes place up to the desorption temperature of {approx}180-230 K. DFT calculations show that intact water on O(2x2)/Ru(0001) is {approx} 0.49 eV more stable than the dissociation products, H and OH, at their preferred fcc and top adsorption sites.

Efficient Solar to Chemical Conversion: 12% Efficient Photoassisted Electrolysis in the [p-type InP(Ru)]/HCl-KCl/Pt(Rh) Cell  

Science Journals Connector (OSTI)

The photoelectrochemical cell [p-type InP(Ru)]/HCl-KCl/Pt(Rh) converts 12% of the incident solar energy into two useful chemicals, hydrogen and chlorine, by photoassisted electrolysis of aqueous hydrochloric acid. At the threshold for electrolysis, the voltage required is reduced from 1.3 to 0.65 V. Hydrogen evolution takes place at microscopic islands of catalysts such as Rh, Ru, and Pt. The high efficiency of the cell derives from a thin surface oxide on InP, preventing carrier recombination, and from efficient transport of electrons to the catalyst.

Giant magnetoresistive structures based on CrO{sub 2} with epitaxial RuO{sub 2} as the spacer layer  

SciTech Connect

Epitaxial ruthenium dioxide (RuO{sub 2})/chromium dioxide(CrO{sub 2}) thin film heterostructures have been grown on (100)-TiO{sub 2} substrates by chemical vapor deposition. Both current-in-plane (CIP) and current-perpendicular-to-plane (CPP) giant magnetoresistive stacks were fabricated with either Co or another epitaxial CrO{sub 2} layer as the top electrode. The Cr{sub 2}O{sub 3} barrier, which forms naturally on CrO{sub 2} surfaces, is no longer present after the RuO{sub 2} deposition, resulting in a highly conductive interface that has a resistance at least four orders of magnitude lower. However, only very limited magnetoresistance (MR) was observed. Such low MR is due to the appearance of a chemically and magnetically disordered layer at the CrO{sub 2} and RuO{sub 2} interfaces when Cr{sub 2}O{sub 3} is transformed into rutile structures during its intermixing with RuO{sub 2}.

Magnetic and orbital orders coupled to negative thermal expansion in Mott insulators Ca2Ru1?xMxO4 (M = Mn and Fe)  

Science Journals Connector (OSTI)

Ca2RuO4 is a structurally driven Mott insulator with a metal-insulator transition at TMI = 357K, followed by a well-separated antiferromagnetic order at TN = 110 K. Slightly substituting Ru with a 3d transition metal ion M effectively shifts TMI by weakening the orthorhombic distortion and induces either metamagnetism or magnetization reversal below TN. Moreover, M doping for Ru produces negative thermal expansion in Ca2Ru1?xMxO4 (M = Cr, Mn, Fe, or Cu); the lattice volume expands on cooling with a total volume expansion ratio, ?V/V, reaching as high as 1%. The onset of the negative thermal expansion closely tracks TMI and TN, sharply contrasting classic negative thermal expansion that shows no relevance to electronic properties. In addition, the observed negative thermal expansion occurs near room temperature and extends over a wide temperature interval up to 300 K. These findings underscore new physics driven by a complex interplay between orbital, spin, and lattice degrees of freedom.

Tuning the magnetic and structural phase transitions of PrFeAsO via Fe/Ru spin dilution  

SciTech Connect

Neutron diffraction and muon spin relaxation measurements are used to obtain a detailed phase diagram of PrFe1{xRuxAsO. The isoelectronic substitution of Ru for Fe acts eectively as spin dilution, suppressing both the structural and magnetic phase transitions. The temperature, TS, of the tetragonal-orthorhombic structural phase transition decreases gradually as a function of x. Slightly below TS coherent precessions of the muon spin are observed corresponding to static magnetism, possibly re ecting a signicant magneto-elastic coupling in the FeAs layers. Short range order in both the Fe and Pr moments persists for higher levels of x. The static magnetic moments disappear at a concentration coincident with that expected for percolation of the J1 - J2 square lattice model.

A highly reactive and stable Ru/Co6?xMgxAl2 catalyst for hydrogen production via methane steam reforming  

Science Journals Connector (OSTI)

Abstract Hydrogen production by methane steam reforming is an important yet challenging process. A performing catalyst will favor the thermodynamic equilibrium while ensuring good hydrogen selectivity. We hereby report the synthesis of a ruthenium based catalyst on a cobalt, magnesium, and aluminum mixed oxides supports. An interaction between cobalt and ruthenium favors the formation of smaller, well dispersed cobalt/ruthenium oxide species. The Ru/Co6Al2 catalyst outmatches the widely used industrial Ru/Al2O3 catalyst. The catalyst is stable for 100hon stream. After test characterization shows the formation of carbon and coke deposits at trace levels. However, this does not affect the catalytic performance of the catalysts making it good candidates for industrial applications.

The measurements on polycrystalline sample were carried out at SPring-8, Japan with 175 keV elliptically polarized synchrotron radiation at 70, 90, 120, 150, and 190 K in 2 T field. The temperature variation of the magnetic effect exhibits clearly the double magnetic transition, i.e., from antiferromagnetic to ferromagnetic and ferromagnetic to paramagnetic transition in agreement with the resistivity and magnetization studies on this material. A comparison of temperature-dependent spin moments in the present sample with Ce(Fe0.96Ru0.04)2 shows interesting features of spin momentum density.

Parametrized linear muffin-tin orbitals atomic-sphere approximation tight-binding scheme: The electronic structure of MoRu alloys  

Science Journals Connector (OSTI)

In this paper we use the recursion method and a linear muffin-tin orbital atomic-sphere approximation (LMTO-ASA) tight-binding (TB) Hamiltonian taken to first order in E-E?, to obtain the electronic structure of Mo-Ru compounds and amorphous clusters of Mo1-xRux for several values of x. It is well known that the LMTO-ASA-TB formalism treats s, p, and d orbitals in an equivalent manner. Therefore it allows the inclusion of important effects, such as the splitting of the center of the bands due to local environment and s-p-d hybridization. These effects are often neglected in the usual parametrized tight-binding Hamiltonians. The LMTO-ASA-TB Hamiltonian used here is parametrized in the sense that potential parameters for the pure metals were used in the calculations and the relative position of the bands in the binaries was adjusted by imposing approximate charge neutrality. But the parametrization is based on a solid theoretical background and no fitting to more exact first-principles calculations is needed. In this paper we show that for the Mo-Ru compounds, a simple parametrized LMTO-ASA-TB Hamiltonian produces good results, when compared to independent first-principles, self-consistent augmented-spherical-wave k-space calculations. We also use the parametrized LMTO-ASA-TB Hamiltonian to obtain the electronic structure of amorphous Mo1-xRux alloys for several values of x. We show that, for these alloys, the density of states at the Fermi level, N(EF), tends to decrease as the Ru concentration increases. This is in agreement with observed experimental tendencies. We note that when the splitting of band centers and s-p-d hybridization are neglected in the calculations, the trends are reversed, with N(EF) increasing as the Ru concentration increases. This illustrates the importance of taking these effects into account.

Rice Rab11 is required for JA-mediated defense signaling  

SciTech Connect

Highlights: OsRab11 interacts with OsOPR8. OsOPR8 is localized in the cytosol and peroxisome. OsRab11 enhances the NADPH consumption by OsOPR8. Transgenic Arabidopsis overexpressing OsRab11 represents a pathogen-resistant phenotype. -- Abstract: Rab proteins play an essential role in regulating vesicular transport in eukaryotic cells. Previously, we characterized OsRab11, which in concert with OsGAP1 and OsGDI3 regulates vesicular trafficking from the trans-Golgi network (TGN) to the plasma membrane or vacuole. To further elucidate the physiological function of OsRab11 in plants, we performed yeast two-hybrid screens using OsRab11 as bait. OsOPR8 was isolated and shown to interact with OsRab11. A co-immunoprecipitation assay confirmed this interaction. The green fluorescent protein-OsOPR8 fusion product was targeted to the cytoplasm and peroxisomes of protoplasts from Arabidopsis thaliana. OsOPR8 exhibited NADPH-dependent reduction activity when 2-cyclohexen-1-one (CyHE) and 12-oxo-phytodienoic acid (OPDA) were supplied as possible substrates. Interestingly, NADPH oxidation by OsOPR8 was increased when wild-type OsRab11 or the constitutively active form of OsRab11 (Q78L) were included in the reaction mix, but not when the dominant negative form of OsRab11 (S28N) was included. OsRab11 was expressed broadly in plants and both OsRab11 and OsOPR8 were induced by jasmonic acid (JA) and elicitor treatments. Overexpressed OsRab11 transgenic plants showed resistance to pathogens through induced expression of JA-responsive genes. In conclusion, OsRab11 may be required for JA-mediated defense signaling by activating the reducing activity of OsOPR8.

Diruthenium Tetracarbonate Trianion, [RuII/III2(O2CO)4]3?, Based Molecule-Based Magnets: Three-Dimensional Network Structure and Two-Dimensional Magnetic Ordering  

SciTech Connect

HxK1-xMII[Ru2(CO3)4](H2O)y(MeOH)z (M = Mn, Fe, Co, Ni, Mg) were synthesized from the reaction of MII and K3[Ru2(CO3)4] in water and are isomorphous with an orthorhombic three-dimensional network structures based on e3-CO32- linkages to Ru2 moieties forming layers and also to trans-MII(OH2)4 sites forming linked chains that connect the layers. They, as well as non-isomorphous M = Cu, magnetically order as canted ferrimagnets with Tc = 4.4 {+-} 1.0 K. The presence of S = 0 MII = Mg(II) has essentially no effect on Tc suggesting that the main magnetic pathway does not occur the through MII-based chains, but only via Ru2{center_dot}...Ru2 linkages that reside in layers. This is a rare example of a magnet based upon a second row transition metal.

The effect of the exchange-correlation functional on H{sub 2} dissociation on Ru(0001)  

SciTech Connect

The specific reaction parameter (SRP) approach to density functional theory (DFT) has enabled a chemically accurate description of reactive scattering experiments for activated H{sub 2}metal systems (H{sub 2} + Cu(111) and Cu(100)), but its application has not yet resulted in a similarly accurate description of non-activated or weakly activated H{sub 2}-metal systems. In this study, the effect of the choice of the exchange-correlation functional in DFT on the potential energy surface and dynamics of H{sub 2} dissociation on Ru(0001), a weakly activated system, is investigated. In total, full potential energy surfaces were calculated for over 20 different functionals. The functionals investigated include functionals incorporating an approximate description of the van der Waals dispersion in the correlation functional (vdW-DF and vdW-DF2 functionals), as well as the revTPSS meta-GGA. With two of the functionals investigated here, which include vdW-DF and vdW-DF2 correlation, it has been possible to accurately reproduce molecular beam experiments on sticking of H{sub 2} and D{sub 2}, as these functionals yield a reaction probability curve with an appropriate energy width. Diffraction probabilities computed with these two functionals are however too high compared to experimental diffraction probabilities, which are extrapolated from surface temperatures (T{sub s}) ? 500 K to 0 K using a DebyeWaller model. Further research is needed to establish whether this constitutes a failure of the two candidate SRP functionals or a failure of the DebyeWaller model, the use of which can perhaps in future be avoided by performing calculations that include the effect of surface atom displacement or motion, and thereby of the experimental T{sub s}.

Covalent Hydration Reactions in Model Monomeric Ru 2,2'-Bipyridine Complexes: Thermodynamic Favorability as a Function of Metal Oxidation and Overall Spin States  

SciTech Connect

Density functional theory (DFT) has been used to investigate the plausibility of water addition to the simple mononuclear ruthenium complexes, [(NH{sub 3}){sub 3}(bpy)Ru=O]{sup 2+}/{sup 3+} and [(NH{sub 3}){sub 3}(bpy)RuOH]{sup 3+}, in which the OH fragment adds to the 2,2{prime}-bipyridine (bpy) ligand. Activation of bpy toward water addition has frequently been postulated within the literature, although there exists little definitive experimental evidence for this type of 'covalent hydration'. In this study, we examine the energetic dependence of the reaction upon metal oxidation state, overall spin state of the complex, as well as selectivity for various positions on the bipyridine ring. The thermodynamic favorability is found to be highly dependent upon all three parameters, with free energies of reaction that span favorable and unfavorable regimes. Aqueous addition to [(NH{sub 3}){sub 3}(bpy)Ru=O]{sup 3+} was found to be highly favorable for the S = 1/2 state, while reduction of the formal oxidation state on the metal center makes the reaction highly unfavorable. Examination of both facial and meridional isomers reveals that when bipyridine occupies the position trans to the ruthenyl oxo atom, reactivity toward OH addition decreases and the site preferences are altered. The electronic structure and spectroscopic signatures (EPR parameters and simulated spectra) have been determined to aid in recognition of 'covalent hydration' in experimental systems. EPR parameters are found to uniquely characterize the position of the OH addition to the bpy as well as the overall spin state of the system.

Deep eutectic solvents (DES) as green reaction media for the redox isomerization of allylic alcohols into carbonyl compounds catalyzed by the ruthenium complex [Ru(?3:?3-C10H16)Cl2(benzimidazole)  

Science Journals Connector (OSTI)

Abstract The bis-allyl Ru(IV) complex [Ru(?3:?3-C10H16)Cl2(benzimidazole)] (1c) is an active catalyst in the redox isomerization of allylic alcohols into saturated carbonyl compounds using, for the first time, Deep eutectic solvents (DES) as reaction media. A series of primary and secondary allylic alcohols could be isomerized into the corresponding carbonyl compounds in the absence of base. Although high activities and selectivities were reached at short reaction times and with low catalyst loadings (0.2mol% in Ru) for monosubstituted allylic alcohols, for their disubstituted counterparts, high catalyst loading and longer reaction times were always required. It is important to note that the catalytic system: i) is active in a large-scale experiment, and ii) could be recycled up to four consecutive runs.

SiO MASERS IN ASYMMETRIC MIRAS. IV. {chi} CYGNI, R AQUILAE, R LEO MINORIS, RU HERCULIS, U HERCULIS, AND U ORIONIS  

SciTech Connect

This is the fourth paper in a series of multi-epoch observations at 7 mm wavelength of the SiO masers in several asymptotic giant branch stars from a sample of Mira variable stars showing evidence of asymmetric structure in the infrared. These stars have been observed interferometrically in the infrared by IOTA and with VLBA measurements of the SiO masers. In this paper, we present the observations of {chi} Cygni ({chi} Cyg), R Aquilae (R Aql), R Leo Minoris (R LMi), RU Herculis (RU Her), U Herculis (U Her), and U Orionis (U Ori). Several radial features with velocity gradients were observed, all with velocities close to systemic furthest from the star and redshifted closer to the stellar surface. Systemic velocities are estimated for several of the stars. No compelling evidence of asymmetry is seen in the maser distributions. All maser rings are approximately twice the near-IR uniform disk diameter and are comparable in size to the extended molecular envelope when such measurements are available.

Fuel Cells Catalyst for Start-up and Shutdown Conditions: Electrochemical, XPS, and TEM Evaluation of Sputter-Deposited Ru, Ir, and Ti on Pt-Nano-Structured Thin Film (NSTF) Support  

SciTech Connect

Minute amounts of Ru, Ir and Ti (2 and 10 g/cm2) sputter-deposited over 3M Pt-coated nano-structured thin film (NSTF) substrate were evaluated as oxygen evolution reaction (OER) catalysts in a polymer electrolyte membrane (PEM) environment. The purpose of the study was to explore the suitability of these elements for modifying both the anode and the cathode catalysts in order to lower the overpotential for the oxidation of water during transient conditions. By keeping the electrode potential as close as possible to the thermodynamic potential for OER, other components in the fuel cell, such as platinum, the gas diffusion layer and the bipolar plates, will be less prone to degradation. While Ru and Ir were chosen due to their high OER activity in aqueous environment, Ti was also included due to its ability to stabilize the OER catalysts. The 3M Pt-NSTF was selected as a stable, carbon-free substrate. The surface chemistry and the morphology of OER catalysts on Pt-NSTF were examined by x-ray photoelectron spectroscopy (XPS) and scanning transmission electron microscopy (STEM). The OER catalytic activity of Ru and Ir in PEMs compares well with their behavior in aqueous environment. It was found that Ru is more active than Ir, that Ir is considerably more stable, while the mass activity of both is higher in comparison with similar OER catalyst.

Surface species formed by the adsorption and dissociation of water molecules on Ru(0001) surface containing a small coverage of carbon atoms studied by scanning tunneling microscopy  

SciTech Connect

The adsorption and dissociation of water on a Ru(0001) surface containing a small amount ({le} 3 %) of carbon impurities was studied by scanning tunneling microscopy (STM). Various surface species are formed depending on the temperature. These include molecular H{sub 2}O, H{sub 2}O-C complexes, H, O, OH and CH. Clusters of either pure H{sub 2}O or mixed H{sub 2}O-OH species are also formed. Each of these species produces a characteristic contrast in the STM images and can be identified by experiment and by ab initio total energy calculations coupled with STM image simulations. Manipulation of individual species via excitation of vibrational modes with the tunneling electrons has been used as supporting evidence.

Optical properties of boron carbide near the boron K edge evaluated by soft-x-ray reflectometry from a Ru/B4C multilayer  

SciTech Connect

Soft-x-ray Bragg reflection from two Ru/B4C multilayers with 10 and 63 periods was used for independent determination of both real and imaginary parts of the refractive index n = 1 -{delta} + i{beta} close to the boron K edge ({approx}188 eV). Prior to soft x-ray measurements, the structural parameters of the multilayers were determined by x-ray reflectometry using hard x rays. For the 63-period sample, the optical properties based on the predictions made for elemental boron major deviations were found close to the K edge of boron for the 10-period sample explained by chemical bonding of boron to B4C and various boron oxides.

Fischer-Tropsch Synthesis: Influence of CO Conversion on Selectivities H2/CO Usage Ratios and Catalyst Stability for a 0.27 percent Ru 25 percent Co/Al2O3 using a Slurry Phase Reactor  

SciTech Connect

The effect of CO conversion on hydrocarbon selectivities (i.e., CH{sub 4}, C{sub 5+}, olefin and paraffin), H{sub 2}/CO usage ratios, CO{sub 2} selectivity, and catalyst stability over a wide range of CO conversion (12-94%) on 0.27%Ru-25%Co/Al{sub 2}O{sub 3} catalyst was studied under the conditions of 220 C, 1.5 MPa, H{sub 2}/CO feed ratio of 2.1 and gas space velocities of 0.3-15 NL/g-cat/h in a 1-L continuously stirred tank reactor (CSTR). Catalyst samples were withdrawn from the CSTR at different CO conversion levels, and Co phases (Co, CoO) in the slurry samples were characterized by XANES, and in the case of the fresh catalysts, EXAFS as well. Ru was responsible for increasing the extent of Co reduction, thus boosting the active site density. At 1%Ru loading, EXAFS indicates that coordination of Ru at the atomic level was virtually solely with Co. It was found that the selectivities to CH{sub 4}, C{sub 5+}, and CO{sub 2} on the Co catalyst are functions of CO conversion. At high CO conversions, i.e. above 80%, CH{sub 4} selectivity experienced a change in the trend, and began to increase, and CO{sub 2} selectivity experienced a rapid increase. H{sub 2}/CO usage ratio and olefin content were found to decrease with increasing CO conversion in the range of 12-94%. The observed results are consistent with water reoxidation of Co during FTS at high conversion. XANES spectroscopy of used catalyst samples displayed spectra consistent with the presence of more CoO at higher CO conversion levels.

Deformation effects and neutrinoless positron ?? decay of Ru96, Pd102, Cd106, Xe124, Ba130, and Dy156 isotopes within a mechanism involving Majorana neutrino mass  

Science Journals Connector (OSTI)

The (?+?+)0? and (??+)0? modes of Ru96, Pd102, Cd106, Xe124, Ba130, and Dy156 isotopes are studied in the projected Hartree-Fock-Bogoliubov framework for the 0+?0+ transition. The reliability of the intrinsic wave functions required to study these decay modes has been established in our earlier works by obtaining an overall agreement between the theoretically calculated spectroscopic properties, namely yrast spectra, reduced B(E2:0+?2+) transition probabilities, quadrupole moments Q(2+) and gyromagnetic factors g(2+), and the available experimental data in the parent and daughter even-even nuclei. In the present work, the required nuclear transition matrix elements are calculated in the Majorana neutrino mass mechanism using the same set of intrinsic wave functions as used to study the two neutrino positron double-? decay modes. Limits on effective light neutrino mass ?m?? and effective heavy neutrino mass ?MN? are extracted from the observed limits on half-lives T1/20?(0+?0+) of (?+?+)0? and (??+)0? modes. We also investigate the effect of quadrupolar correlations vis-a-vis deformation on nuclear transition matrix elements (NTMEs) required to study the (?+?+)0? and (??+)0? modes.

Reductive atmosphere of supercritical water with RuO2 resulting in TcO2 colloid: Spectroscopic, morphological and crystallographic study on solutions and precipitates in Hastelloy C-22  

Science Journals Connector (OSTI)

In order to study the complicated behavior of technetium observed under various conditions of supercritical water (SCW), i.e. quantitative transfer to solid phase, strong adsorption onto the metal surface, or efficient dissolution from the metal surface, solutions and precipitates prepared in reactors made of Hastelloy C-22 in contact with the SCW containing technetium solutions were studied by absorption spectroscopy, TEM, EDX and electron diffraction. Under SCW with or without H2O2, NiCr2O4 and NiMoO4 was produced as the scales (corrosion products) of Hastelloy C-22. Under SCW with RuO2 the formation of colloidal structure comprised of ruthenium metal and TcO2, which may be named as Tc-Ru-Colloid, were observed. It is worthy of note that the formation of TcO42? from pertechnatate TcO4? (+0.596V) and the disproportionation of TcO42? is plausible at present in spite of the moderate reductive atmosphere (?0.533 to +0.114V) estimated from the observation (the existence of TcO2 and the absence of NiMoO4) by TEM and electron diffraction.

They are substitutional variants of the Zn{sub 11}Rh{sub 18}B{sub 8} structure type, space group P4/mbm (No. 127) and contain a scaffold structural unit (M-ladders interacting with M/Ti-chains) as well as isolated M/Ti-chains. According to DFT calculations, the RuX (X=B, Ti, Ti/M) bonding interactions are nearly constant throughout the series and responsible for the structural stability of these phases, whereas the MM and RuM interactions vary significantly with varying valence electron count. Furthermore, density of states (DOS) analyses predict the phases with M=Mn and Ni to develop a total magnetic moment but not the M=Co phase. Susceptibility measurements confirm the Co phase to be paramagnetic and the Mn Phase orders ferrimagnetically below 120 K and thus develops a magnetic moment, as predicted. - Graphical abstract: The crystal structures of the new phases (M=Cr, Mn, Co, Ni) are confirmed by Rietveld refinement of powder diffraction data and single crystal X-ray diffraction (for M=Co) to contain beside the M-ladder also M/Ti-chains. Similar to the series Ti{sub 9}M{sub 2}Ru{sub 18}B{sub 8}, the crystal structure of the new phases are mainly stabilized by the heteroatomic RuB and RuTi bonds that remain nearly constant throughout the series, whereas the M-containing bonds vary significantly with varying valence electron count. An experimental finding confirmed and even extended by COHP bonding analyses. In addition, the DOS analyses of the M-elements reveal the development of magnetic moments for the M=Mn, Ni cases but not for M=Co. Indeed, Ti{sub 8}Co{sub 3}Ru{sub 18}B{sub 8} was found experimentally to be a paramagnet and ferrimagnetic ordering below 120 K is found for M=Mn. Highlights: Synthesis of the valence electron controlled borides Ti{sub 9?x}M{sub 2+x}Ru{sub 18}B{sub 8} (M=CrNi). Prediction of magnetic properties of Ti{sub 9?x}M{sub 2+x}Ru{sub 18}B{sub 8}. Ferrimagnetic ordering found in Ti{sub 8}M{sub 3}Ru{sub 18}B{sub 8}. Chemical bonding studied by density functional theory.

Nuclear deformation and neutrinoless double-? decay of Zr94,96, Mo98,100, Ru104, Pd110, Te128,130, and Nd150 nuclei within a mechanism involving neutrino mass  

Science Journals Connector (OSTI)

The (?-?-)0? decay of Zr94,96, Mo98,100, Ru104, Pd110, Te128,130, and Nd150 isotopes for the 0+?0+ transition is studied in the projected Hartree-Fock-Bogoliubov framework. In our earlier work, the reliability of HFB intrinsic wave functions participating in the ?-?- decay of the above-mentioned nuclei has been established by obtaining an overall agreement between the theoretically calculated spectroscopic properties, namely yrast spectra, reduced B(E2:0+?2+) transition probabilities, quadrupole moments Q(2+), gyromagnetic factors g(2+) as well as half-lives T1/22? for the 0+?0+ transition and the available experimental data. In the present work, we study the (?-?-)0? decay for the 0+?0+ transition in a mechanism involving neutrino mass and extract limits on effective mass of light as well as heavy neutrinos from the observed half-lives T1/20?(0+?0+) using nuclear transition matrix elements calculated with the same set of wave functions. Further, the effect of deformation on the nuclear transition matrix elements required to study the (?-?-)0? decay in such a mass mechanism is investigated. It is noticed that the deformation effect on nuclear transition matrix elements is of approximately the same magnitude in (?-?-)2? and (?-?-)0? decay.

Reversible chemisorption on highly dispersed Ru catalysts  

SciTech Connect

Hydrogen and carbon monoxide adsorptions have been studied by static gas volumetric measurement on a range of highly dispersed Y-zeolite-supported ruthenium catalysts prepared by ion exchange. At ambient temperature, the absorption isotherms indicated two distinct types of adsorption - reversible (composed of both physisorption and weak chemisorption) and irreversible (strongly chemisorbed). The catalysts were highly dispersed and had average particle diameters ranging from 0.9 to 1.6 nm. Reversible hydrogen chemisorption was found to be a function of average particle diameter and dispersion. On the other hand, reversible carbon monoxide chemisorption seemed to be mainly due to interaction with the support.
