Structure and properties of bimetallic Ru-Fe/Al/sub 2/O/sub 3/ catalysts  

SciTech Connect

The authors studied the influence of the composition of Ru-Fe-/Al/sub 2/O/sub 3/-catalysts on adsorption and interaction of carbon monoxide and hydrogen. Moessbauer investigations were conducted. According to x-ray photoelectron spectra (XPS) bimetallic Ru-Fe/Al/sub 2/O/sub 3/ catalysts contain ruthenium mainly in the form of Ru/sup 0/ (E/sub b/ = 280.8 eV). Adsorption of carbon monoxide, hydrogen, and CO + H/sub 2/ mixture was studied by microcalorimetric and thermal-desorption methods.

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.

Ordered vs. disordered perovskites; structural studies of Fe-doped SrIrO{sub 3} and SrRuO{sub 3}  

SciTech Connect

The structures of the two Fe containing perovskites Sr{sub 2}IrFeO{sub 6} and SrRu{sub 0.5}Fe{sub 0.5}O{sub 3} have been established using a combination of synchrotron and neutron diffraction methods. Sr{sub 2}IrFeO{sub 6} and SrRu{sub 0.5}Fe{sub 0.5}O{sub 3} are shown to be monoclinic I2/m and tetragonal I4/mcm respectively The former exhibits a rock-salt like ordering of the Fe and Ir cations and displays a sequence of phase transitions associated with the loss of the octahedral tilts upon heating; 12/m?I4/m?Fm3{sup ¯}m. The Fe and Ru cations are disordered in SrRu{sub 0.5}Fe{sub 0.5}O{sub 3} and this shows a single structural phase transition upon heating due to the loss of the in-phase tilts, viz. I4/mcm?Pm3{sup ¯}m. In both cases XANES measurements show partial oxidation of the Fe{sup 3+} to Fe{sup 4+}. The difference in the structures between the two is remarkable given the similar size of Ir{sup 5+} and Ru{sup 5+}, and this is reflected in their magnetic properties. - Graphical abstract: Sr{sub 2}IrFeO{sub 6} and SrRu{sub 0.5}Fe{sub 0.5}O{sub 3} are shown, using a combination of synchrotron and neutron diffraction, to be monoclinic I2/m with cation ordering and tetragonal I4/mcm with disordered Fe and Ir, respectively.

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.

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.

Temperature-dependent magnetic Compton scattering study of spin moments in Ce(Fe0.94Ru0.06)2  

Science Journals Connector (OSTI)

We report on the study of spin moments in Ce(Fe0.94Ru0.06)2 using magnetic Compton scattering. 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.

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.

Theoretical study of the magnetic x-ray dichroism of Os, Ir, Pt, and Au impurities in Fe  

Science Journals Connector (OSTI)

The electronic structure of the 5d impurities Os, Ir, Pt, and Au in ferromagnetic Fe has been studied by the spin-polarized, relativistic version of the Korringa-Kohn-Rostoker Green’s-function method. This approach simultaneously treats spin polarization and spin-orbit coupling and naturally allows for a theoretical investigation of effects arising from an interplay of both. Here the polarization dependence of x-ray absorption (magnetic x-ray dichroism) is considered. For all the impurities studied, the agreement with recent experimental L2 and L3 absorption spectra is very satisfactory. For Pt in Fe, a decomposition of the spectra into various absorption channels is presented and the applicability of a simplified model is discussed that interprets the spectra in terms of a spin-polarized band structure alone.

Metal segregation in supported bimetallic catalysts:. gamma. -Al/sub 2/O/sub 3/-supported CO hydrogenation catalysts prepared from RhOs/sub 3/, Rh/sub 4/, and FeOs/sub 3/ clusters  

SciTech Connect

Al/sub 2/O/sub 3/-supported metals were prepared from (H/sub 2/RhOs/sub 3/(CO)/sub 10/(acetylacetonate)), (Rh/sub 4/(CO)/sub 12/), and (H/sub 2/FeOs/sub 3/(CO)/sub 13/). The samples were characterized by infrared spectroscopy after reaction with CO + H/sub 2/ and tested as catalysts for conversion of CO + H/sub 2/ in a flow reactor at 200 and 270/sup 0/C and 10 atm. Used catalysts were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, infrared spectroscopy, and elemental analysis. The catalyst lost Os during operation, presumably as a result of formation of volatile carbonyls. The catalytic reaction products were a nearly Schulz-Flory-Anderson distribution of hydrocarbons with small yields of dimethyl ether (formed from methanol). The performance of the catalyst prepared from the RhOs/sub 3/ clusters was closely similar to that of the catalyst prepared from the Rh/sub 4/ cluster. Characterization of the samples after treatment in CO + H/sub 2/ and after catalysis demonstrated that the RhOs/sub 3/ clusters broke apart, first giving triosmium clusters and mononuclear Rh complexes and then, at higher temperatures, giving Rh crystallites and mononuclear Os complexes. The catalytic activity for hydrocarbon synthesis is attributed to the Rh metal; the activity for methanol synthesis is tentatively associated with ionic Rh complexes. The FeOs/sub 3/ catalyst was two orders of magnitude less active than the Rh Os/sub 3/ catalyst, apparently consisting of small iron oxide particles and mononuclear Os complexes. The selectivity of this catalyst for dimethyl ether formation increased markedly with time onstream in the flow reactor; after 55 h, 36 mol% of the organic product was ether. 25 refs., 5 figs., 3 tabs.

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.

Contrasting carrier doping effects in the Kondo insulator CeOs2Al10: The influential role of c?f hybridization in spin-gap formation  

Science Journals Connector (OSTI)

The effects of electron (Ir) and hole (Re) doping on the hybridization gap and antiferromagnetic order have been studied by magnetization, muon spin relaxation (?+SR), and inelastic neutron scattering on polycrystalline samples of Ce(Os1?xIrx)2Al10 (x=0.08 and 0.15) and Ce(Os1?yRey)2Al10 (y=0.03). ?+SR spectra clearly reveal bulk magnetic ordering below 20 and 10 K for x=0.08 and 0.15 samples, respectively, with heavily damped oscillations of the muon asymmetry. Our important findings are that a small amount of electron doping (i) completely suppresses the inelastic magnetic excitations at low temperatures, which were observed at 11 meV in the undoped compound, and the magnetic response transforms into a broad quasielastic response, and (ii) surprisingly, the internal field at the corresponding muon site is remarkably enhanced by an order of magnitude compared with the parent compound. Moreover, a small amount (3% Re) of hole doping results in a significant reduction of the intensity of 11 meV peak and an increased c?f hybridization, which is in agreement with the reduction of the Ce ordered moment seen through neutron diffraction and ?+SR. The main origin of the observed doping effect is an extra 5d electron being carried by Ir and a hole carried by Re with respect to the Os atom. The absence of a spin gap/spin wave, despite a larger ordered state moment of Ce, in the electron-doped system cannot be explained based on a conventional theory of magnetism. Thus, the obtained results demonstrate a great sensitivity to the carrier doping and provide additional ways to study the anomalous magnetic properties in the CeT2Al10 (T= Fe, Ru, and Os).

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.

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

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 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.

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 ?0.5–0.7 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?+?1.4×1020 yr, T1/22???+?8.0×1019 yr, and T1/20?2K?1.0×1021 yr (all limits are at 90% C.L.). The resonant neutrinoless double-electron captures to the 2700.2 and 2712.7 keV excited states of 96Mo are restricted as T1/20?KL?2.0×1020 yr and T1/20?2L?3.6×1020 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 ?6.5×1020 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).

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.

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

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.

Syntrophic Effects in a Subsurface Clostridial Consortium on Fe(III)-(Oxyhydr)oxide Reduction and Secondary Mineralization  

SciTech Connect

In this study, we cultivated from subsurface sediments an anaerobic Clostridia 25 consortium that was composed of a fermentative Fe-reducer Clostridium species (designated as 26 strain FGH) and a novel sulfate-reducing bacterium belonging to the Clostridia family 27 Vellionellaceae (designated as strain RU4). In pure culture, Clostridium sp. strain FGH mediated 28 the reductive dissolution/transformation of iron oxides during growth on peptone. When 29 Clostridium sp. FGH was grown with strain RU4 on peptone, the rates of iron oxide reduction 30 were significantly higher. Iron reduction by the consortium was mediated by multiple 31 mechanisms, including biotic reduction by Clostridium sp. FGH and biotic/abiotic reactions 32 involving biogenic sulfide by strain RU4. The Clostridium sp. FGH produced hydrogen during 33 fermentation, and the presence of hydrogen inhibited growth and iron reduction activity. The 34 sulfate-reducing partner strain RU4 was stimulated by the presence of H2 gas and generated 35 reactive sulfide which promoted the chemical reduction of the iron oxides. Characterization of 36 Fe(II) mineral products showed the formation of magnetite during ferrihydrite reduction, and 37 the precipitation of iron sulfides during goethite and hematite reduction. The results suggest an 38 important pathway for iron reduction and secondary mineralization by fermentative sulfate-39 reducing microbial consortia is through syntrophy-driven biotic/abiotic reactions with biogenic 40 sulfide.

Quantum effects in the diffusion of hydrogen on Ru(0001)  

E-Print Network (OSTI)

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.

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.

Thermal stability of hexagonal OsB2  

SciTech Connect

The synthesis of novel hexagonal ReB2-type OsB2 ceramic powder was performed by high energy ball milling of elemental Os and B powders. Two different sources of B powder have been used for this mechanochemical synthesis. One B powder consisted of a mixture of amorphous and crystalline phases and a mixture of 10B and 11B isotopes with a fine particle size, while another B powder was a purely crystalline (rhombohedral) material consisting of enriched 11B isotope with coarse particle size. The same Os powder was used for the synthesis in both cases. It was established that, in the first case, the hexagonal OsB2 phase was the main product of synthesis with a small quantity of Os2B3 phase present after synthesis as an intermediate product. In the second case, where coarse crystalline 11B powder was used as a raw material, only Os2B3 boride was synthesized mechanochemically. The thermal stability of hexagonal OsB2 powder was studied by heating under argon up to 876 C and cooling in vacuo down to 225 C. During the heating, the sacrificial reaction 2OsB2+3O2 2Os+2B2O3 took place due to presence of O2/water vapor molecules in the heating chamber, resulting in the oxidation of B atoms and formation of B2O3 and precipitation of Os metal out of the OsB2 lattice. As a result of such phase changes during heating, the lattice parameters of hexagonal OsB2 changed significantly. The shrinkage of the a lattice parameter was recorded in 276 426 C temperature range upon heating, which was attributed to the removal of B atoms from the OsB2 lattice due to oxidation followed by the precipitation of Os atoms and formation of Os metal. While significant structural changes occurred upon heating due to presence of O2, the hexagonal OsB2 ceramic demonstrated good phase stability upon cooling in vacuo with linear shrinkage of the lattice parameters and no phase changes detected during cooling.

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 structure and multiphonon {gamma} vibrations in very neutron-rich {sup 114}Ru  

SciTech Connect

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 = 80–400 K and N{sub A}{sup Ru} ? 9.5 × 10{sup 19}?5.7 × 10{sup 20} cm{sup ?3} (x = 0–0.03), 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 475.0 K 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 50 GPa 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 0 GPa and 50 GPa 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 structure–property 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 Curie–Weiss 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 Ru–Ru 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.

Triaxial shape coexistence and new aligned band in Os178  

Science Journals Connector (OSTI)

High spin states in Os178 were studied by means of Ho165(Ne20,p6n)Os178 fusion evaporation reaction at a beam energy of 150?MeV, using a clover detector array. Several new transitions belonging to Os178 were placed in a level scheme and a new aligned rotational band was observed in addition to earlier known bands. Spin-parity assignments for most of the proposed levels were made using the deduced directional correlation orientation and polarization measurements for the de-exciting transitions. Experimental results are compared with the projected angular momentum deformed Hartree-Fock model calculations and cranked Woods-Saxon model calculations. This nucleus is predicted to be prolate deformed in the ground state but the ?-softness at higher excitation is revealed by the cranked Woods-Saxon model and the geometrical asymmetric model calculations.

Hydrogen production by methane steam reforming over Ru supported on Ni–Mg–Al mixed oxides prepared via hydrotalcite route  

Science Journals Connector (OSTI)

Abstract Catalytic performance of Ru/NixMg6?xAl2 800 800 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 800 °C, impregnated with 0.5 wt.% ruthenium using ruthenium (III) nitrosyl nitrate Ru(NO) (NO3)3 precursor and then calcined again at 800 °C 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 (0.5 wt.%), ruthenium oxide particles are formed but are well dispersed over the surface of the oxide NixMg6?xAl2 800. Ru/Ni6Al2 800 800 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 Ni–Ru 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 Å3 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.

Band-theoretical investigation of the magneto-optical Kerr effect in Fe and Co multilayers  

Science Journals Connector (OSTI)

A band theory of the magneto-optical (MO) properties of solids, based on the first-principles spin-polarized, relativistic linear muffin-tin orbital method, is described. Two expressions of the relativistic electron-photon-interaction matrix elements are implemented and their accuracies are investigated. It is found that the spin-polarized, relativistic band theory, together with the expression of the photon-absorption matrix elements, is able to give reliable optical conductivity and MO Kerr rotation spectra of bcc Fe that agree well with both experiments and recent calculations using a different method. The MO properties of several Fe and Co multilayers [Fe(Co)2Cu6 fcc-(001), FeCu(Ag)5 fcc-(001), bcc-Fe/fcc-Ag5 (001), bcc-Fen/fcc-Au5 (001) (n=1,3), Co2Pd4 fcc-(111), and Co2Ptm fcc-(111) (m=1,4,7)] are then investigated theoretically. The calculated MO Kerr effect in all the multilayers except Co2Pt1 fcc-(111) is not larger than in bulk Fe and Co. Nevertheless, the results suggest that materials with larger Kerr rotations can be achieved by making Fe (Co) superlattices with ultrathin layers (few monolayers thick) of heavy elements possessing a partially filled d band (e.g., Pt and Os).Kerr rotation spectra for Fe(Co)/Cu(Ag, Au, Pd, Pt) bilayers [i.e., a thin layer of Fe (Co) on the Cu (Ag, Au, Pd, Pt) substrate] are also obtained from the calculated optical conductivity tensors of Fe, Co, Cu, Ag, Au, Pd, and Pt. It is found that the MO Kerr effect in the Fe (Co)/noble-metal bilayers is considerably enhanced near the plasma edge of the substrate. This indicates that one can obtain good MO materials by fabricating Fe (Co) bilayers using nonmagnetic metals with a sharp plasma edge (e.g., Ag and Al) as substrates. Calculated Kerr rotation spectra of the Fe and Co multilayers as well as bilayers are in satisfactory agreement with available experiments. The spin and orbital magnetic moments in the Fe and Co multilayers are also calculated, and possible correlations between these and MO properties of the Fe and Co multilayers are discussed.

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.

Reduction of pertechnetate [Tc(VII)] by aqueous Fe(II) and the nature of solid phase redox products  

Science Journals Connector (OSTI)

The subsurface behaviour of 99Tc, a contaminant resulting from nuclear fuels reprocessing, is dependent on its valence (e.g., IV or VII). Abiotic reduction of soluble Tc(VII) by Fe(II)(aq) in pH 6–8 solutions was investigated under strictly anoxic conditions using an oxygen trap (<7.5 × 10?9 atm O2). The reduction kinetics were strongly pH dependent. Complete and rapid reduction of Tc(VII) to a precipitated Fe/Tc(IV) form was observed when 11 ?mol/L of Tc(VII) was reacted with 0.4 mmol/L Fe(II) at pH 7.0 and 8.0, while no significant reduction was observed over 1 month at pH 6.0. Experiments conducted at pH 7.0 with Fe(II)(aq) = 0.05–0.8 mmol/L further revealed that Tc(VII) reduction was a combination of homogeneous and heterogeneous reaction. Heterogeneous reduction predominated after approximately 0.01 mmol/L of Fe(II) was oxidized. The heterogeneous reaction was more rapid, and was catalyzed by Fe(II) that adsorbed to the Fe/Tc(IV) redox product. Wet chemical and Fe–X-ray absorption near edge spectroscopy measurements (XANES) showed that Fe(II) and Fe(III) were present in the Fe/Tc(IV) redox products after reaction termination. 57Fe-Mössbauer, extended X-ray adsorption fine structure (EXAFS), and transmission electron microscopy (TEM) measurements revealed that the Fe/Tc(IV) solid phase was poorly ordered and dominated by Fe(II)-containing ferrihydrite with minor magnetite. Tc(IV) exhibited homogeneous spatial distribution within the precipitates. According to Tc-EXAFS measurements and structural modeling, its molecular environment was consistent with an octahedral Tc(IV) dimer bound in bidentate edge-sharing mode to octahedral Fe(III) associated with surface or vacancy sites in ferrihydrite. The precipitate maintained Tc(IV)aq concentrations that were slightly below those in equilibrium with amorphous Tc(IV)O2·nH2O(s). The oxidation rate of sorbed Tc(IV) in the Fe/Tc precipitate was considerably slower than Tc(IV)O2·nH2O(s) as a result of its intraparticle/intragrain residence. Precipitates of this nature may form in anoxic sediments or groundwaters, and the intraparticle residence of sorbed/precipitated Tc(IV) may limit 99Tc remobilization upon the return of oxidizing conditions.

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.

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.

We show that a simple model involving two narrow (?500 K) peaks in the density of states (DOS) at the edges of a narrow (?1000 K) gap can account for the observed anomalies in the magnetic susceptibility, specific heat, thermal expansion, and elastic response of FeSi. We also show that the resistivity of FeSi, including the metal-insulator ‘‘transition’’ at about 300 K, is well described by this model. Recent band-structure calculations, although predicting the correct value for the semiconducting gap, are unable to account for the narrow peaks in the DOS needed to explain the thermodynamics. We conclude that, given the available alternatives, a Kondo insulator description—involving an extreme renormalization of the noninteracting bands—is most appropriate for FeSi.

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.

Computed oscillator strengths and energy levels for Fe III, Fe IV, Fe V, and Fe VI with calculated wavelengths and wavelengths derived from established data  

Science Journals Connector (OSTI)

Calculated weighted oscillator strengths are tabulated for spectral lines of Fe III, Fe IV, Fe V, and Fe VI. The lines belong to transition arrays 3d6-3d54p and 3d54s-3d54p in Fe III, 3d5-3d44p and 3d44s-3d44p in Fe IV, 3d4-3d34p and 3d34s-3d34p in Fe V, and 3d3-3d24p and 3d24s-3d24p in Fe VI. For the calculations, Slater parameters are optimized on the basis of minimizing the discrepancies between observed and computed wavelengths. Configuration interaction was included among the 3dn, 3dn?14s, 3dn?24s2, 3dn?14d, and 3dn?15s even configurations and among the 3dn?14p, 3dn?24s4p, and 3dn?15p odd configurations, with 3p53dn+1 added for Fe VI. Calculated wavelengths are compared with observational data, and the compositions of energy levels are listed. This completes a series of similar computations for these complex configurations covering Fe I to Fe VI.

USING Fe-PILC as catalyst  

Science Journals Connector (OSTI)

Fe pillared clays (Fe-PILCs) were synthesized and characterized by X-ray diffraction (XRD), surface area, thermogravimetric analysis (TGA) and 57Fe Mössbauer spectroscopy. Hydrodeporphyrinization (HDP) of vanadyl octaetil porphyrine (VOOEP) and hydrodesulfurization (HDS) of thiophene were used as catalytic tests. It was demonstrated that Fe-PILCs are very active catalysts for the HDP of VOOEP. After sulfidation of the Fe-PILC, some of the iron forms a bulk pyrrhotite-type iron sulfide (Fe1?xS) phase and the Fe-PILC structure is partially destroyed by the sulfiding procedure. About half of the iron remains forming a pillar structure. Both, the segregated iron sulfide and the iron in the pillars, are active for the decomposition of the VOOEP.

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.

THE SPECTRUM OF Fe II  

SciTech Connect

The spectrum of singly ionized iron (Fe II) has been recorded using high-resolution Fourier transform (FT) and grating spectroscopy over the wavelength range 900 A to 5.5 {mu}m. The spectra were observed in high-current continuous and pulsed hollow cathode discharges using FT spectrometers at the Kitt Peak National Observatory, Tucson, AZ and Imperial College, London and with the 10.7 m Normal Incidence Spectrograph at the National Institute of Standards and Technology. Roughly 12,900 lines were classified using 1027 energy levels of Fe II that were optimized to measured wavenumbers. The wavenumber uncertainties of lines in the FT spectra range from 10{sup -4} cm{sup -1} for strong lines around 4 {mu}m to 0.05 cm{sup -1} for weaker lines around 1500 A. The wavelength uncertainty of lines in the grating spectra is 0.005 A. The ionization energy of (130,655.4 {+-} 0.4) cm{sup -1} was estimated from the 3d{sup 6}({sup 5}D)5g and 3d{sup 6}({sup 5}D)6h levels.

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}.

Low-Dimensional Water on Ru(0001)Model System for X-ray Absorption Spectroscopy Studies of Liquid Water  

SciTech Connect

We present an x-ray absorption spectroscopy results for fully broken to a complete H-bond network of water molecules on Ru(0001) by varying the morphology from isolated water molecules via two-dimensional clusters to a fully covered monolayer as probed by scanning tunneling microscopy. The sensitivity of x-ray absorption to the symmetry of H-bonding is further elucidated for the amino (-NH{sub 2}) group in glycine adsorbed on Cu(110) where the E-vector is parallel either to the NH donating an H-bond or to the non-H-bonded NH. The results give further evidence for the interpretation of the various spectral features of liquid water and for the general applicability of x-ray absorption spectroscopy to analyze H-bonded systems.

Re–Os depositional ages and seawater Os estimates for the Frasnian–Famennian boundary: Implications for weathering rates, land plant evolution, and extinction mechanisms  

Science Journals Connector (OSTI)

Four TOC-rich shale intervals spanning the Frasnian–Famennian (F–F) boundary were recovered in a drillcore (West Valley NX-1) from western New York (USA) and radiometrically dated using Re–Os. Two of the black shale intervals (WVC785 from ? 2.9 m below, and WVC754 from ? 6.4 m above the F–F boundary, respectively) yielded statistically overlapping ages with uncertainties of < 1.1%. An interpolated age and associated graphically determined uncertainty of 372.4 ± 3.8 Ma provides new absolute age constraints on the F–F boundary. This date is ? 4.1 Ma younger than the latest proposed F–F boundary age of 376.1 Ma obtained by interpolation of U–Pb dates from volcanic zircon [Kaufmann, B., 2006. Calibrating the Devonian Time Scale: A synthesis of U–Pb ID-TIMS ages and conodont stratigraphy. Earth-Science Reviews 76, 175–190], and within uncertainty of the International Commission on Stratigraphy accepted date of 374.5 ± 2.6 Ma. A third date (from sample WVC802, ? 8.2 m beneath the F–F boundary) yielded an imprecise age of 357 ± 23 Ma, owing in part to a limited Re/Os range. The initial 187Os/188Os (0.45 to 0.47), reflecting contemporaneous seawater Os values, are low but similar to the value of 0.42 reported for the Exshaw Fm (Canada) at the Devonian–Mississippian boundary (ca. 361 Ma) [Selby D., Creaser R.A., 2005. Direct radiometric dating of the Devonian–Mississippian time-scale boundary using the Re–Os black shale geochronometer. Geology 33, 545–548]. This may suggest fairly constant and low global continental weathering rates during the Late Devonian, although in view of the short residence time of Os in seawater (? 1–4 × 104 yr), further measurements are needed to assess potential short-term variation in seawater Os ratios. Owing to low Os and Re abundances at the F–F boundary, our data are inconsistent with long-term volcanism and bolide impact as potential Late Devonian mass extinction mechanisms. In addition, the Frasnian–Famennian ocean appears to have been depleted with respect to Re, possibly indicating an exhaustion of the Re seawater reservoir owing to high burial rates of redox-sensitive elements under dysoxic/anoxic conditions leading up to the F–F boundary.

Photo-disintegration cross section measurements on $^{186}$W, $^{187}$Re and $^{188}$Os: Implications for the Re-Os cosmochronology  

E-Print Network (OSTI)

Cross sections of the $^{186}$W, $^{187}$Re, $^{188}$Os($\\gamma,n$) reactions were measured using quasi-monochromatic photon beams from laser Compton scattering (LCS) with average energies from 7.3 to 10.9 MeV. The results are compared with the predictions of Hauser-Feshbach statistical calculations using four different sets of input parameters. In addition, the inverse neutron capture cross sections were evaluated by constraining the model parameters, especially the $E1$ strength function, on the basis of the experimental data. The present experiment helps to further constrain the correction factor $F_{\\sigma}$ for the neutron capture on the 9.75 keV state in $^{187}$Os. Implications of $F_{\\sigma}$ to the Re-Os cosmochronology are discussed with a focus on the uncertainty in the estimate of the age of the Galaxy.

Viscosity of liquid Fe at high pressure  

Science Journals Connector (OSTI)

Synchrotron x-ray radiography has been used to measure the viscosity of pure liquid Fe at high pressure and temperature in a large volume press. A probe sphere rising through liquid Fe at high pressure and temperature is imaged, in situ, allowing for the derivation of sample viscosity through a modified form of Stokes’ equation. The effect of pressure on viscosity is fit by the semi empirical framework for transport coefficients in liquid metals, providing experimental verification of constant viscosity at the pressure-dependent melting temperature of liquid Fe where no change in liquid structure occurs.

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 100 h on 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.

Magnetism of HgSe:Fe  

Science Journals Connector (OSTI)

The perpendicular and parallel components of the magnetization of the mixed valence system Hg1-xFexSe in the strongly dilute limit (xmagnetic fields up to 20 T. In this interesting semimagnetic semiconductor the overall magnetization is caused simultaneously by Fe3+ (Brillouin paramagnet), Fe2+ (van Vleck paramagnet), and free electrons (diamagnetic de Haas-van Alphen effect). Using a torque magnetometer the various contributions with their anisotropy are individually determined. For very low iron content (xmagnetic moment perpendicular to the magnetic field when applying the field in a nonsymmetric direction of the crystal. Using recent theoretical results on the energy-level diagram of Fe2+ in the Td symmetry of a HgSe host lattice we deduce a spin-orbit level splitting of 2 meV from our experimental data. In contrast to higher concentration samples, both the Brillouin paramagnetism of Fe3+ and the van Vleck paramagnetism of Fe2+ can be attributed to the sum from individual Fe donors with no obvious magnetic interaction between them. Finally, we also have measured de Haas-van Alphen oscillations of the conduction-band electrons with amplitudes of the same order as the paramagnetic background. From the measured crystal-field-induced anisotropy in the magnetic moment we deduce a Fermi-surface anisotropy of about 7%.

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.

Surface magnetism of Fe(001)  

Science Journals Connector (OSTI)

Results of all-electron self-consistent semirelativistic full-potential linearized augmented-plane-wave local-density and local-spin-density studies are reported for a seven-layer Fe(001) thin film. The calculated work function for the ferromagnetic state is found to be in excellent agreement with experiment, whereas that calculated for the paramagnetic state is significantly worse (namely, 0.5 eV too large), indicating the importance of spin polarization on this electrostatic property. For both states, partial densities of states (projected by layer and by orbital angular momentum), surface states, and charge (and spin) densities are presented and their differences employed to discuss the origin of surface magnetism. No Friedel oscillation is found in the layer-by-layer charge density. The surface-layer magnetic moment is found to have been increased by 0.73?B from the center layer to 2.98?B/atom; a very small Friedel oscillation is obtained for the spin density, which indicates possible size effects in this seven-layer film. Layer-by-layer Fermi contact hyperfine fields are presented: While the core-polarization contributions are proportional to the magnetic moment, the conduction-electron contribution shows a pronounced Friedel oscillation in the central layer and, significantly, a change of sign and increase in the magnitude for the surface-layer contribution. The hyperfine field at the nucleus of the center-layer atoms is found to be in excellent agreement with experiment. The net result for the surface-layer atoms is a predicted decrease in magnitude of the total Fermi contact hyperfine field despite the large increase of their magnetic moments. The relevance of this prediction to experiment is discussed.

Electronic Properties of LiFePO4 and Li doped LiFePO4  

SciTech Connect

LiFePO{sub 4} has several potential advantages in comparison to the transition metal oxide cathode materials used in commercial lithium-ion batteries. However, its low intrinsic electronic conductivity ({approx} 10{sup -9} S/cm) is problematic. We report here a study by soft x-ray absorption/emission spectroscopy of the electronic properties of undoped LiFePO{sub 4} and Li-doped LiFePO{sub 4} in which Li{sup +} ions are substituted for Fe{sup 2+} ions in an attempt to increase the intrinsic electronic conductivity. The conductivities of the Li{sub 1+x}Fe{sub 1-x}PO{sub 4} samples were, however, essentially unchanged from that of the undoped LiFePO{sub 4}. Nonetheless, evidence for changing the electronic properties of LiFePO{sub 4} by doping with excess Li+ was observed by the XAS/XES spectroscopy. New pre-edge features the O-1s XAS spectrum of Li{sub 1.05}Fe{sub 0.95}PO4 is a direct indication that the charge compensation for substitution of Fe{sup 2+} by Li{sup +} resides in the unoccupied O-2p orbitals. A charge transfer (CT) excitation was also observed in the doped material implying that the unoccupied O-2p orbitals created by doping are strongly hybridized with unoccupied Fe-3d orbitals of neighboring sites. However, the strong covalent bonding within the (PO{sub 4}){sup 3-} anions and the large separation of the Fe cations means that the charge created by doping is not delocalized in the manner of electrons or holes in a semiconductor.

Electronic Properties of LiFePO4 and Li doped LiFePO4  

SciTech Connect

The potential use of different iron phosphates as cathodematerials in lithium-ion batteries has recently been investigated.1 Oneof the promising candidates is LiFePO4. This compound has severaladvantages in comparison to the state-of-the-art cathode material incommercial rechargeable lithium batteries. Firstly, it has a hightheoretical capacity (170 mAh/g). Secondly, it occurs as mineraltriphylite in nature and is inexpensive, thermally stable, non-toxic andnon-hygroscopic. However, its low electronic conductivity (~;10-9 S/cm)results in low power capability. There has been intense worldwideresearch activity to find methods to increase the electronic conductivityof LiFePO4, including supervalent ion doping,2 introducingnon-carbonaceous network conduction3 and carbon coating, and theoptimization of the carbon coating on LiFePO4 particle surfaces.4Recently, the Li doped LiFePO4 (Li1+xFe1-xPO4) synthesized at ARL hasyield electronic conductivity increase up to 106.5 We studied electronicstructure of LiFePO4 and Li doped LiFePO4 by synchrotron based soft X-rayemission (XES) and X-ray absorption (XAS) spectroscopies. XAS probes theunoccupied partial density of states, while XES the occupied partialdensity of states. By combining XAS and XES measurements, we obtainedinformation on band gap and orbital character of both LiFePO4 and Lidoped LiFePO4. The occupied and unoccupied oxygen partial density ofstates (DOS) of LiFePO4 and 5 percent Li doped LiFePO4 are presented inFig. 1. Our experimental results clearly indicate that LiFePO4 has wideband gap (~; 4 eV). This value is much larger than what is predicted byDFT calculation. For 5 percent Li doped LiFePO4, a new doping state wascreated closer to the Fermi level, imparting p-type conductivity,consistent with thermopower measurement. Such observation substantiatesthe suggestion that high electronic conductivity in Li1.05Fe0.95 PO4 isdue to available number of charge carriers in the material. Furthermore,Hall effect measurement on Li doped sample confirmed presence of freecharge carriers, which are responsible for the observed electronicconductivity increase in Li doped LiFePO4. There is no evidence that Fe3+valence is created by doping with excessive Li+ in Li1.05Fe0.95PO4, asshown by Fe-edge XAS. (Fig.2) Instead, charge-carrier holes resideprimarily in unoccupied O 2p states, which compensate for the chargedeficiency from Li+ substitution for Fe2+. The increased conductivity inLi1.05Fe0.95PO4 is attributed to the new charge carriers (doped holes)and the strong electron correlation between O 2p and Fe 3dstates.

FeP precipitates in hydride?vapor phase epitaxially grown InP:Fe  

Science Journals Connector (OSTI)

Fe?doped InP was grown by hydride?vapor phase epitaxy.Doping levels up to 8×1018 cm?3 were determined by secondary ion mass spectrometry. Additionally performed photoluminescence measurements revealed a homogeneous distribution of electrically active Fe atoms. From microstructural investigations by analytical transmission electron microscopy spherical?shaped precipitates were detected in plan?view samples. These precipitates with diameters up to 13 nm are homogeneously arranged in the epilayer. For conglomerates of precipitates a distinct enrichment with Fe and P was measured by a comparative energy dispersive x?ray analysis. The lattice plane distances of the precipitates were deduced from the electron diffraction patterns and from high?resolution electron micrographs. A comparison with calculated values for different Fe–P alloys indicates that the precipitates consist mainly of orthorhombic FeP.

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

SciTech Connect

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

The mechanical properties of FeAl  

SciTech Connect

Only in the last few years has progress been made in obtaining reproducible mechanical properties data for FeAl. Two sets of observations are the foundation of this progress. The first is that the large vacancy concentrations that exist in FeAl at high temperature are easily retained at low temperature and that these strongly affect the low-temperature mechanical properties. The second is that RT ductility is adversely affected by water vapor. Purpose of this paper is not to present a comprehensive overview of the mechanical properties of FeAl but rather to highlight our understanding of key phenomena and to show how an understanding of the factors which control the yield strength and fracture behavior has followed the discovery of the above two effects. 87 refs, 9 figs.

Using x-ray absorption and resonant inelastic x-ray scattering, charge dynamics at and near the Fe L edges is investigated in Fe pnictide materials, and contrasted to that measured in other Fe compounds. It is shown that the XAS and RIXS spectra for 122 and 1111 Fe pnictides are each qualitatively similar to Fe metal. Cluster diagonalization, multiplet, and density-functional calculations show that Coulomb correlations are much smaller than in the cuprates, highlighting the role of Fe metallicity and strong covalency in these materials. Best agreement with experiment is obtained using Hubbard parameters U {approx}< 2eV and J {approx} 0.8eV.

Inelastic neutron scttering study o fcrystal field levels in PrOs4As12  

SciTech Connect

We use neutron scattering to study the Pr$^{3+}$ crystalline electric field (CEF) excitations in the filled skutterudite PrOs$_4$As$_{12}$. By comparing the observed levels and their strengths under neutron excitation with the theoretical spectrum and neutron excitation intensities, we identify the Pr$^{3+}$ CEF levels, and show that the ground state is a magnetic $\\Gamma_4^{(2)}$ triplet, and the excited states $\\Gamma_1$, $\\Gamma_4^{(1)}$ and $\\Gamma_{23}$ are at 0.4, 13 and 23~meV, respectively. A comparison of the observed CEF levels in PrOs$_4$As$_{12}$ with the heavy fermion superconductor PrOs$_4$Sb$_{12}$ reveals the microscopic origin of the differences in the ground states of these two filled skutterudites.

Investigation of anomalously high transition strength for the 21+ state in 174Os through lifetime measurement  

Science Journals Connector (OSTI)

The lifetime of the 21+ state in 174Os was measured in a fast timing experiment using LaBr3(Ce) crystals for ?-ray detection. The excellent energy resolution in conjunction with the superb time properties of the new material allows for the reliable handling of the background, thus providing very precise lifetime values. The resulting B(E2,21+?01+) transition strength is discussed in relation to the systematics of the previously reported B(E2,21+?01+) values in the Os isotopes and compared to predictions of several models. The maximum of the transition probabilities of the 21+ states at N=98 for W and Os nuclei may be interpreted as resulting from the effects of the deformed subshell at N=98 as well as the “intruder” proton h9/2 orbital.

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 Debye–Waller model. Further research is needed to establish whether this constitutes a failure of the two candidate SRP functionals or a failure of the Debye–Waller 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.

Corrosion performance of Fe-Cr-Al and Fe aluminide alloys in complex gas environments  

SciTech Connect

Alumina-forming structural alloys can offer superior resistance to corrosion in the presence of sulfur-containing environments, which are prevalent in coal-fired fossil energy systems. Further, Fe aluminides are being developed for use as structural materials and/or cladding alloys in these systems. Extensive development has been in progress on Fe{sub 3}Al-based alloys to improve their engineering ductility. In addition, surface coatings of Fe aluminide are being developed to impart corrosion resistance to structural alloys. This paper describes results from an ongoing program that is evaluating the corrosion performance of alumina-forming structural alloys, Fe-Al and Fe aluminide bulk alloys, and Fe aluminide coatings in environments typical of coal-gasification and combustion atmospheres. Experiments were conducted at 650-1000{degrees}C in simulated oxygen/sulfur gas mixtures. Other aspects of the program are corrosion evaluation of the aluminides in the presence of HCl-containing gases. Results are used to establish threshold Al levels in the alloys for development of protective alumina scales and to determine the modes of corrosion degradation that occur in the materials when they are exposed to S/Cl-containing gaseous environments.

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 (0.2 mol% 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.

Reaction characteristics of Al/Fe2O3 nanocomposites  

Science Journals Connector (OSTI)

Al/Fe2O3 nonacomposites have explosive and high exothermic properties by thermite reaction. In this study, Al/Fe2O3 xerogel nanocomposites were prepared by sol–gel method and thermite reaction performance was compared with those prepared by physical mixing with sonication. Scanning electron microscopy (SEM) images of Al/Fe2O3 xerogel nanocomposites show that network structure of Fe2O3 gel covers Al nanoparticles efficiently and this indicates that improvement of thermite reaction performance due to close contact between a fuel and an oxidizer. Optimum mole ratio of Al/Fe was determined to be 2 by thermite reaction performance by differential scanning calorimetry (DSC) analysis. At Al/Fe ratio of 2, thermite reaction enthalpy of the Al/Fe2O3 xerogel nancomposite was 991.4 J/g, which was higher by a factor of four than that of the nanocomposite prepared by physical mixing.

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.

Magnetic interlayer exchange coupling in epitaxial Fe/Si/Fe(001) studied by polarized neutron reflectometry  

Science Journals Connector (OSTI)

Polarized neutron reflectometry (PNR) has been used to investigate the magnetic interlayer coupling in a MBE-grown Fe/Si/Fe(001) sandwich at room temperature and at 10 K. Both the magnitude and orientation of the magnetic moments of the Fe layers are obtained from a rigorous analysis of the PNR data. Orthogonal configurations of the Fe magnetizations were observed, providing unambiguous evidence for the presence of a biquadratic term in the exchange coupling energy. The competition between the bilinear and biquadratic exchange couplings results in distinct orthogonal and antiparallel configurations of the Fe magnetizations at room temperature. A previously unresolved magnetic configuration in the room-temperature hysteresis curve was identified by the PNR measurements as a 180° spin-flop transition. The dominant role of the biquadratic coupling at low temperatures is evident from the orthogonal configuration of the magnetizations at remanence in the measurements at T=10 K. The magnetic configurations deduced by PNR are in good agreement with those obtained by fitting the magnetic hysteresis loops using a global energy minimum calculation.

Proteome of Geobacter sulfurreducens grown with Fe(III) oxide or Fe(III) citrate as the electron acceptor.  

SciTech Connect

e(III) oxides are the most abundant source of reducible Fe(III) by microorganisms in most soils and sediments, yet few studies on the physiology of Fe(III)-reducing microorganisms during growth on Fe(III) oxide have been conducted because of the technical difficulties in working with cell growth and harvest in the presence of Fe(III) oxides. Geobacter sulfurreducens is a representative of the Geobacter species that predominate in a variety of subsurface environments in which Fe(III) oxide is important. In order to better understand the physiology of Geobacter species during growth on Fe(III) oxide, the proteome of G. sulfurreducens grown on Fe(III) oxide was compared with the proteome of cells grown with soluble Fe(III) citrate. Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) revealed 19 proteins that were more abundant during growth on Fe(III) oxide than on soluble Fe(III). These included proteins related to protein synthesis, electron transfer and energy production, oxidative stress, protein folding, outer membrane proteins, nitrogen metabolism and hypothetical proteins. Further analysis of the proteome with the accurate mass and time (AMT) tag method revealed additional proteins associated with growth on Fe(III) oxide. These included the outer-membrane c-type cytochrome, OmcS and OmcG, which genetic studies have suggested are required for Fe(III) oxide reduction. Furthermore, several other cytochromes, as yet unstudied, were detected to be significantly up regulated during growth on Fe(III) oxide and other proteins of unknown function were more abundant during growth on Fe(III) oxide than on soluble Fe(III). PilA, the structural protein for pili, which is required for Fe(III) oxide reduction, and other pilin-associated proteins were also more abundant during growth on Fe(III) oxide. Confirmation of the differential expression of proteins known to be important in Fe(III) oxide reduction was observed, and an additional number of previously unidentified proteins were found with significant abundance in the cells grown under conditions of Fe(III) oxide reduction.

Photo- and thermal-induced antiferromagnetic interlayer coupling in Fe/(Fe-Si) superlattices  

SciTech Connect

We have grown via sputtering, Fe - iron silicide superlattices that exhibit novel thermal and photomagnetic effects. For {approximately}15 {Angstrom} nominal thickness of the silicide layer the superlattices are antiferromagnetically (AF) coupled at room temperature. Upon cooling below 100K, they gradually revert to ferromagnetic alignment, but the AF coupling is restored at low temperature by exposure to visible light off sufficient intensity (> 10 mW/mm{sup 2}). These effects are due to charge carriers in the silicide spacer layer which, when thermally or photo-generated, are capable of communicating spin information between the Fe layers.

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.

Superconductivity in LiFeO2Fe2Se2 with anti-PbO-type spacer layers  

Science Journals Connector (OSTI)

We report on a superconductor LiFeO2Fe2Se2 with Tc?43 K, synthesized via the hydrothermal method. The anti-PbO-type spacer layer of LiFeO2 has been successfully intercalated between the anti-PbO-type FeSe layer, which results in a high-Tc superconductivity in this iron selenide material. In this material, the LiFeO2 layer is electrically neutral and does not act as an electron donor, which is remarkably different from other heavily electron-doped intercalated FeSe-derived superconductors. Based on our results and previous reports on FeSe-based superconductors, we figure out a V-shaped anion height from the Fe layer dependence of Tc in the FeSe-derived superconductors, which is in contrast to the inverse V-shaped one for the FeAs-based superconductors. Our studies expand the categories of the iron-based superconductors and open a door in the quest for potential superconductors with various spacer layers, which is helpful for the study of the underlying physics in iron-based high-Tc superconductors.

XANES study of Fe-implanted strontium titanate  

SciTech Connect

Properties of strontium titanate SrTiO{sub 3} (STO) depend to a great extent on the substitutional dopants and defects of crystal structure. The ion beam implantation method was used for doping STO (001) crystals with Fe at different doses. Implanted samples were then annealed at 350°C in oxygen to induce recrystallization and remove oxygen vacancies produced during ion implantation process. The effect of Fe doping and post-implantation annealing was studied by X-ray Absorption Near Edge Spectroscopy (XANES) method and Superconducting Quantum Interference Device (SQUID). XANES allowed to monitor the change in structure of STO crystals and in the local environment of Fe following the implantation and annealing steps. SQUID measurements revealed correlation between magnetic moment and Fe implantation dose. Ferromagnetic hysteresis was observed on selected Fe-implanted STO at 5 K. The observed magnetic properties can be correlated with the several Fe oxide phases in addition to the presence of O/Ti vacancies.

Investigation of the Fe1+xSb system  

Science Journals Connector (OSTI)

X-ray diffraction, bulk magnetization, and Fe57 Mössbauer spectroscopic measurements on Fe1+xSb system for various values of x (0.14?x?0.35) are reported. The x-ray data suggest that the ASTM (American Society for Testing and Materials) data file for Fe1+xSb should be modified. The lattice Néel temperatures obtained from magnetic susceptibility and Mössbauer spectroscopic measurements are in nice agreement with each other and decrease linearly with increase in x. The Néel temperatures for the ordering of interstitial Fe atoms are higher than 60 K and increase with x. The low-temperature Mössbauer spectra have been analyzed in terms of a Lorentzian distribution of the magnetic hyperfine field at lattice sites, a low-field site, and a relatively high-field interstitial site. Also included are comments on the low magnetic moment of Fe in Fe1+xSb.

Magnetism of Mn layers on Fe(100)  

Science Journals Connector (OSTI)

The magnetic state of epitaxial overlayers of Mn grown on Fe(100) is studied using spin-polarized electron energy loss spectroscopy. Nonzero exchange asymmetries are found, demonstrating that the surface layer of the Mn overlayers has a net magnetic moment. The exchange asymmetry oscillates with a period of about two atomic layers as the Mn overlayer thickness is varied, proving that the Mn forms ferromagnetic (100) sheets and that the sheets align antiferromagnetically. The average Mn exchange splitting is found to be 2.9 eV, indicating a magnetic moment of the order 3?B.

Structure and Properties of Magnetic (Co, Fe, Fe{sub 3}C and Ni) Carbon Beads  

SciTech Connect

Nanoparticles exhibit unique physical properties due to the surface or quantum-size effects. Particular attention has been focused on magnetic nanoparticles and substantial progress has been done in this field. In this work magnetic composites, consisting of elementary metals or carbides nanocrystallites, stabilized in carbon matrix, were prepared by the procedure comprising formation of appropriate metal acrylamide complexes, followed by frontal polymerization and pyrolysis of the polymer at various temperatures. Application of frontal polymerization and further pyrolysis enables formation of composite beads consisting of Co, Fe, Fe{sub 3}C or Ni nanocrystallites stabilized in carbon matrix. It was found that the lowest pyrolysis temperature, which enables the production of metallic nanocrystallites, was 673 K for Co and Ni, and 773 K for Fe. The magnetic properties of the beads, percentage of the metallic component, their composition and shape depended on the pyrolysis temperature. Extracts on the basis of composites containing Fe{sub 3}C showed no cytotoxicity, whereas those containing Co and Ni exhibited negligible cytotoxicity up to concentrations of 6.25 mg/ml.

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.

Advances in Fe(VI) charge storage: Part I. Primary alkaline super-iron batteries  

Science Journals Connector (OSTI)

Recent advances in super-iron batteries, based on an unusual Fe(VI) cathodic charge storage, are presented. Fe(VI) cathodes that have been demonstrated in super-iron batteries include the synthesized Fe(VI) compound with three-electron cathodic charge capacity Na2FeO4, K2FeO4, Rb2FeO4, Cs2FeO4 (alkali Fe(VI) salts), alkali earth Fe(VI) salts BaFeO4, SrFeO4, and also a transition Fe(VI) salt Ag2FeO4 which exhibits a five-electron cathodic charge storage. This paper focus on the primary alkaline Fe(VI) charge storage in aqueous electrolyte systems. Primary alkaline super-iron batteries exhibit a higher capacity than conventional alkaline batteries. Configuration optimization, enhancement and mediation of Fe(VI) cathode charge transfer of primary Fe(VI) alkaline batteries are summarized. Composite Fe(VI)/Mn(IV or VII), Fe(VI)/Ag(II) and zirconia coating stabilized Fe(VI)/Ag(II) cathode alkaline batteries are also illustrated.

Biostimulation of Iron Reduction and Subsequent Oxidation of Sediment Containing Fe-silicates and Fe-oxides: Effect of Redox Cycling on Fe(III) Bioreduction  

SciTech Connect

Microbial reduction of iron has been shown to be important in the transformation and remediation of contaminated sediments. Re-oxidation of microbially reduced iron may occur in sediments that experience oxidation-reduction cycling and can thus impact the extent of contaminant remediation. The purpose of this research was to quantify iron oxidation in a flow-through column filled with biologically-reduced sediment and to compare the iron phases in the re-oxidized sediment to both the pristine and biologically-reduced sediment. The sediment contained both Fe(III)-oxides (primarily goethite) and silicate Fe (illite/vermiculite) and was biologically reduced in phosphate buffered (PB) medium during a 497 day column experiment with acetate supplied as the electron donor. Long-term iron reduction resulted in partial reduction of silicate Fe(III) without any goethite reduction, based on Mössbauer spectroscopy measurements. This reduced sediment was treated with an oxygenated PB solution in a flow-through column resulting in the oxidation of 38% of the biogenic Fe(II). Additional batch experiments showed that the Fe(III) in the oxidized sediment was more quickly reduced compared to the pristine sediment, indicating that oxidation of the sediment not only regenerated Fe(III) but also enhanced iron reduction compared to the pristine sediment. Oxidation-reduction cycling may be a viable method to extend iron-reducing conditions during in-situ bioremediation.

Physical Properties of Intermetallic FE2VA1  

SciTech Connect

Fe{sub 2}VAl has recently been discovered to have a negative temperature coefficient of resistivity, moderately enhanced specific heat coefficient, and a large DOS at the Fermi level by photoemission. This triggered a round of heated research to understand the ground state of this material, both theoretically and experimentally. here they report a comprehensive characterization of Fe{sub 2}VAl. X-ray diffraction exhibited appreciable antisite disorder in all of our samples. FTIR spectroscopy measurements showed that the carrier density and scattering time had little sample-to-sample variation or temperature dependence for near-stoichiometric samples. FTIR and DC resistivity suggest that the transport properties of Fe{sub 2}VAl are influenced by both localized and delocalized carriers, with the former primarily responsible for the negative temperature coefficient of resistivity. Magnetization measurements reveal that near-stoichiometric samples have superparamagnetic clusters with at least two sizes of moments. X-ray photoemission from Fe core level showed localized magnetic moments on site-exchanged Fe. They conclude that in Fe{sub 2}VAl, antisite disorder causes significant modification to the semi-metallic band structure proposed by LDA calculations. With antisite disorder considered, they are now able to explain most of the physical properties of Fe{sub 2}VAl.

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.

Photoluminescence properties and energy levels of RE (RE?=?Pr, Sm, Er, Tm) in layered-CaZnOS oxysulfide  

SciTech Connect

RE{sup 3+} (RE?=?Pr, Sm, Er, Tm)-activated CaZnOS samples were prepared by a solid-state reaction method at high temperature, and their photoluminescence properties were investigated. Doping with RE{sup 3+} (RE?=?Pr, Sm, Er, Tm) into layered-CaZnOS resulted in typical RE{sup 3+} (RE?=?Pr, Sm, Er, Tm) f-f line absorptions and emissions, as well as the charge transfer band of Sm{sup 3+} at about 3.3?eV. The energy level scheme containing the position of the 4f and 5d levels of all divalent and trivalent lanthanide ions with respect to the valence and conduction bands of CaZnOS has been constructed based on the new data presented in this work, together with the data from literature on Ce{sup 3+} and Eu{sup 2+} doping in CaZnOS. The detailed energy level scheme provides a platform for interpreting the optical spectra and could be used to comment on the valence stability of the lanthanide ions in CaZnOS.

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.

Atom probe: a direct technique for kinetic measurements. [Fe-24Cr; Fe-32Cr; Fe-28. 5Cr-10. 6Co  

SciTech Connect

The atom probe has been used to study the phase transformations occurring within the low-temperature miscibility gaps in Fe-Cr and Fe-Cr-Co alloys. The morphology of the two-phase microstructure resulting from phase separation deep within the miscibility gaps was found to be highly interconnected and charactristic of an isotropic spinodal reaction. The characteristic dimensions of the microstructure and the changes in composition were measured as a function of aging. The coarsening of the network structures could be fitted with a power law with time exponents that were significantly less than the classical Lifshitz-Slyozov-Wagner value of one-third.

MEASUREMENT OF THE Fe VIII-Fe XVI 3-3 EMISSION IN THE EXTREME ULTRAVIOLET AND COMPARISON WITH CHIANTI  

SciTech Connect

Laboratory measurements of the n = 3 to n = 3 emission from M-shell iron ions are presented and compared to synthetic spectra from the CHIANTI spectral model. The measurements cover the range 170-290 Angstrom-Sign and are made at an electron density of about 10{sup 11} cm{sup -3}. Emission from Fe VIII through Fe XVI has been identified. Excellent agreement with CHIANTI predictions is found for most lines. Twenty weaker features are noted in the laboratory data that are either absent in CHIANTI or have recently been added and correspond to lines that have not been verified by experimental measurements. A few of these lines may have already been observed (but not yet identified) in the Sun. The features are attributed to emission from various charge states of iron, notably Fe IX and Fe XIII, and two features have been identified as transitions in Fe VIII, i.e., the 3p{sup 6}3d {sup 2}D{sub 5/2}-3p {sup 5}3d{sup 2} {sup 2}P{sub 3/2} and the 3p {sup 6}3d {sup 2}D{sub 3/2}-3p {sup 5}3d{sup 2} {sup 2}P{sub 1/2} transitions at 225.25 {+-} 0.12 and 226.35 {+-} 0.10 Angstrom-Sign , respectively. Seven lines in Fe XI, Fe XII, and Fe XIII between 200 and 205 Angstrom-Sign are noted for which the wavelengths in the CHIANTI database disagree with those in the current database of the National Institute of Standards and Technology. Our measurements of five of these lines appear to agree with the assignments used in CHIANTI.

Campbell penetration depth in Fe-based superconductors  

SciTech Connect

A 'true' critical current density, j{sub c}, as opposite to commonly measured relaxed persistent (Bean) current, j{sub B}, was extracted from the Campbell penetration depth, {lambda}{sub c}(T,H) measured in single crystals of LiFeAs, and optimally electron-doped Ba(Fe{sub 0.954}Ni{sub 0.046}){sub 2}As{sub 2} (FeNi122). In LiFeAs, the effective pinning potential is nonparabolic, which follows from the magnetic field - dependent Labusch parameter {alpha}. At the equilibrium (upon field - cooling), {alpha}(H) is non-monotonic, but it is monotonic at a finite gradient of the vortex density. This behavior leads to a faster magnetic relaxation at the lower fields and provides a natural dynamic explanation for the fishtail (second peak) effect. We also find the evidence for strong pinning at the lower fields.The inferred field dependence of the pinning potential is consistent with the evolution from strong pinning, through collective pinning, and eventually to a disordered vortex lattice. The value of j{sub c}(2 K) {approx_equal} 1.22 x 10{sup 6} A/cm{sup 2} provide an upper estimate of the current carrying capability of LiFeAs. Overall, vortex behavior of almost isotropic, fully-gapped LiFeAs is very similar to highly anisotropic d-wave cuprate superconductors, the similarity that requires further studies in order to understand unconventional superconductivity in cuprates and pnictides. In addition to LiFeAs, we also report the magnetic penetration depth in BaFe{sub 2}As{sub 2} based superconductors including irradiation of FeNi122. In unirradiated FeNi122, the maximum critical current value is, j{sub c}(2K) {approx_equal} 3.3 x 10{sup 6} A/cm{sup 2}. The magnetic-dependent feature was observed near the transition temperature in FeTe{sub 0.53}Se{sub 0.47} and irradiated FeNi122. Because of this feature, further studies are required in order to properly calibrate the Campbell penetration depth. Finally, we detected the crossing between the magnetic penetration depth and London penetration depth in optimally hold-doped Ba{sub 0.6}K{sub 0.4}Fe{sub 2}As{sub 2} (BaK122) and isovalent doped BaFe{sub 2}(As{sub 0.7}P{sub 0.3}){sub 2} (BaP122). These phenomena probably coincide with anomalous Meissner effect reported in pnicitde superconductors [Prozorov et al. (2010b)] however more studies are needed in order to clarify this.

Heterogeneous reduction of Tc(VII) by Fe(II) at the solid–water interface  

Science Journals Connector (OSTI)

Experiments were performed herein to investigate the rates and products of heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to hematite and goethite, and by Fe(II) associated with a dithionite–citrate–bicarbonate (DCB) reduced natural phyllosilicate mixture [structural, ion-exchangeable, and edge-complexed Fe(II)] containing vermiculite, illite, and muscovite. The heterogeneous reduction of Tc(VII) by Fe(II) adsorbed to the Fe(III) oxides increased with increasing pH and was coincident with a second event of Fe 2 + (aq) adsorption. The reaction was almost instantaneous above pH 7. In contrast, the reduction rates of Tc(VII) by DCB-reduced phyllosilicates were not sensitive to pH or to added Fe 2 + (aq) that adsorbed to the clay. The reduction kinetics were orders of magnitude slower than observed for the Fe(III) oxides, and appeared to be controlled by structural Fe(II). The following affinity series for heterogeneous Tc(VII) reduction by Fe(II) was suggested by the experimental results: aqueous Fe(II) ? adsorbed Fe(II) in phyllosilicates [ion-exchangeable and some edge-complexed Fe(II)] ? structural Fe(II) in phyllosilicates ? Fe(II) adsorbed on Fe(III) oxides. Tc-EXAFS spectroscopy revealed that the reduction products were virtually identical on hematite and goethite that were comprised primarily of sorbed octahedral TcO2 monomers and dimers with significant Fe(III) in the second coordination shell. The nature of heterogeneous Fe(III) resulting from the redox reaction was ambiguous as probed by Tc-EXAFS spectroscopy, although Mössbauer spectroscopy applied to an experiment with 56Fe-goethite with adsorbed 57Fe(II) implied that redox product Fe(III) was goethite-like. The Tc(IV) reduction product formed on the DCB-reduced phyllosilicates was different from the Fe(III) oxides, and was more similar to Tc(IV) oxyhydroxide in its second coordination shell. The heterogeneous reduction of Tc(VII) to less soluble forms by Fe(III) oxide-adsorbed Fe(II) and structural Fe(II) in phyllosilicates may be an important geochemical process that will proceed at very different rates and that will yield different surface species depending on subsurface pH and mineralogy.

Growth sequence and interface formation in the Fe/MgO/Fe(001) tunnel junction analyzed by surface x-ray diffraction  

SciTech Connect

We present a surface x-ray diffraction study of the interface geometric structure in the Fe/MgO/Fe(001) magnetic tunnel junction (MTJ). While the lower MgO/Fe(001) interface is characterized by a substoichiometric FeO{sub x} (x=0.6{+-}0.1) layer in agreement with previous studies, growth of Fe on the MgO spacer and the upper Fe/MgO interface structure strongly depends on the preparation method. If 0.4 monolayers of Fe are initially deposited in ambient oxygen atmosphere (p=10{sup -7} mbar) followed by Fe deposition under ultrahigh-vacuum (UHV) conditions, structural coherence across the trilayer junction is observed. In this case, substoichiometric FeO{sub x} layers are present at both Fe/MgO interfaces corresponding to a symmetric MTJ structure. In contrast, lattice registry is not preserved if Fe deposition is carried out solely under UHV conditions. Our results might have important implications for the preparation of magnetic tunnel junctions optimized to achieve giant tunneling-magnetoresistance amplitudes.

Electron-Ion Recombination Rate Coefficients and Photoionization Cross Sections for Astrophysically Abundant Elements. V. Relativistic calculations for Fe XXIV and Fe XXV for X-ray modeling  

E-Print Network (OSTI)

Photoionization and recombination cross sections and rate coefficients are calculated for Li-like Fe XXIV and He-like Fe XXV using the Breit-Pauli R-matrix (BPRM) method. A complete set of total and level-specific parameters is obtained to enable X-ray photoionization and spectral modeling. The ab initio calculations for the unified (e + ion) recombination rate coefficients include both the non-resonant and the resonant recombination (radiative and di-electronic recombination, RR and DR, respectively) for (e + Fe XXV) -> Fe XXIV and (e + Fe XXVI) -> Fe XXV. The level specific rates are computed for all fine structure levels up to n = 10, enabling accurate computation of recombination-cascade matrices and effective rates for the X-ray lines. The total recombination rate coefficients for both Fe XXIV and Fe XXV differ considerably, by several factors, from the sum of RR and DR rates currently used to compute ionization fractions in astrophysical models. As the photoionization/recombination calculations are carried out using an identical eigenfunction expansion, the cross sections for both processes are theoretically self-consistent; the overall uncertainty is estimated to be about 10-20%. All data for Fe XXIV and Fe XXV (and also for H-like Fe XXVI, included for completeness) are available electronically.

Formation of FePt nanoparticles by organometallic synthesis  

SciTech Connect

Our interest in determining the mechanism of FePt nanoparticle formation has led to this study of the evolution of particle size and composition during synthesis. FePt nanoparticles were prepared by the simultaneous reduction of platinum acetylacetonate and thermal decomposition of iron pentacarbonyl. During the course of the reaction, samples were removed and the particle structure, size, and composition were determined using x-ray diffraction, transmission electron microscopy (TEM), and scanning electron microscopy-energy dispersive x-ray spectrometry. Early in the reaction the particles were Pt rich (greater than 95 at. % Pt) and as the reaction proceeded the Fe content increased to the target of 50%. The particle diameter increased from 3.1 to 4.6 nm during the reaction. Energy dispersive x-ray spectrometry measurements of individual particle compositions using a high resolution TEM showed a broad distribution of particle compositions with a standard deviation greater than 15% of the average composition.

Bimetallic Fe-Ni Oxygen Carriers for Chemical Looping Combustion  

SciTech Connect

The relative abundance, low cost, and low toxicity of iron make Fe-based oxygen carriers of great interest for chemical looping combustion (CLC), an emerging technology for clean and efficient combustion of fossil and renewable fuels. However, Fe also shows much lower reactivity than other metals (such as Ni and Cu). Here, we demonstrate strong improvement of Fe-based carriers by alloying the metal phase with Ni. Through a combination of carrier synthesis and characterization with thermogravimetric and fixed-bed reactor studies, we demonstrate that the addition of Ni results in a significant enhancement in activity as well as an increase in selectivity for total oxidation. Furthermore, comparing alumina and ceria as support materials highlights the fact that reducible supports can result in a strong increase in oxygen carrier utilization.

We cannot also exclude a possibility that the increasing content of maghemite is caused by a stabilization of the spinel structure by ferrous cations, which may be generated by a reaction of iron oxide with an incompletely oxidized sucrose at higher temperature. ...

Magnetic spiral structures in La/Fe multilayers.  

SciTech Connect

The magnetic properties of La/Fe multilayers were tested by magneto-optical Kerr effect and polarized neutron reflectometry. The experiments indicated that above a layer thickness t{sub la} = 25{angstrom} the magnetic state of the virgin sample is represented by a spiral-like arrangement of magnetizations of subsequent Fe layers, whereas each Fe layer itself is ferromagnetic. Polarized neutron reflectometry shows that the helix has predominantly one chirality over the entire surface area of several cm{sup 2}. Tine magnetic spiral structure is imprinted during the growth process by rotating the sample in a small residual magnetic field. External magnetic field of 90 Oe are sufficient to erase the magnetic structure irreversibly.

Influence of Fe Contamination on the Minority Carrier Lifetime of Multi-crystalline Silicon  

Science Journals Connector (OSTI)

We investigate the influence of Fe contamination on the minority carrier lifetimes of multi-crystalline silicon. The minority carrier lifetime is measured by the microwave photoconductive decay method. The original bulk lifetime is about 30 ?s after passivation with iodine solution. After intentional Fe contamination, the bulk lifetime declines with increasing temperature. Fast cooling in air conduces to the formation of more interstitial Fe ([Fe]i). Slow cooling through the control of the furnace temperature limits the formation of more [Fe]i, but leads to the formation of precipitation. The data support the idea that the minority carrier lifetime in multi-crystalline silicon mainly depends on the distribution of Fe but not the total amount. A favorite effect of [Fe]i gettering is discovered after conventional phosphorus diffusion, and the [Fe]i concentration remaining in the silicon wafer is acceptable for solar cell applications.

Interaction and charge transfer in the iron nitride Fe4N  

Science Journals Connector (OSTI)

The linearized augmented-plane-wave method has been used to calculate the electronic bands of the cubic iron nitride Fe4N. Strong interaction between N 2p and Fe 4s orbitals of nearest Fe atoms (FeII has been revealed. This interaction leads to an increase in the N 2p population. The Fe 3d bands remain almost the same as in the pure Fe metal with negligible interaction with neighboring N orbitals. However, the occupation of the FeII 3d bands and the total number of electrons of FeII atoms increases due to less screening. This unified picture clarifies the controversy in the previous explanations of the experimental results obtained from magnetic measurements, electron diffraction, and photoelectron spectroscopy.

Catalyst characterisation of Fe-doped-titanium dioxide  

Science Journals Connector (OSTI)

Fe (5 wt. %) doped TiO2 was synthesised using a hydrothermal method. This material was characterised by X-Ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM) imaging, BET surface area, X-Ray photoelectron spectroscopy (XPS) and ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS). The BET surface area was 136 m²/g and crystal sizes of 1.6 microns. SEM results showed crystal structures that were regular and pyramidal in shape. This catalyst only showed anatase phase. This favoured phase could be due to iron ions inserted into the TiO2 lattice and forming Ti-O-Fe bonds. It was found that doping TiO2 with 5 wt. % Fe caused a red shift in the absorption of the material to the visible light range and there was an increased absorption in the ultraviolet-visible diffuse reflectance spectroscopy, in the 450-590 nm range. These characteristics are very favourable for the use of 'free' visible light in order to activate the Fe (5 wt. %) doped TiO2 photocatalyst.

Magnetization of uncovered and V-covered ultrathin Fe(100) films on V(100)  

SciTech Connect

We used polarized neutron reflectometry (PNR) to determine the absolute magnetic moment of uncovered and V-covered Fe films in the thickness range from 0.3 to 5.5 nm. The films were prepared by molecular beam epitaxy on a V(100) buffer layer grown on a MgO(100) crystal. The magnetic moment shows a linear dependence on the Fe film thickness with a reduction (compared to the Fe bulk value) of the magnetic moment equivalent to 0.1 nm bulk Fe for the V-covered films and a reduction equivalent to 0.03 nm bulk Fe for the uncovered Fe films. For the case of the V/Fe/V samples we observe a much smaller reduction of the magnetic moment than reported for experiments on Fe/V multilayers. As theoretical calculations show a strong decrease of the magnetic moment for an interface alloy we conclude that the larger reduction of the magnetization in Fe/V multilayers is due to an increase in interface roughness with increasing film thickness. For the uncovered Fe(100) films we find a much smaller reduction of the magnetic moment than in earlier in situ PNR experiments on V(110)/Fe(110) where we observed a reduction equivalent to 0.4 nm bulk Fe.

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? (+0.596 V) and the disproportionation of TcO42? is plausible at present in spite of the moderate reductive atmosphere (?0.533 to +0.114 V) estimated from the observation (the existence of TcO2 and the absence of NiMoO4) by TEM and electron diffraction.

Complex magnetic behavior of the sawtooth Fe chains in Rb2Fe2O(AsO4)2  

SciTech Connect

Results of magnetic eld and temperature dependent neutron diraction and magnetization mea- surements on oxy-arsenate Rb2Fe2O(AsO4)2 are reported. The crystal structure of this compound contains pseudo-one-dimensional [Fe2O6] sawtooth-like chains, formed by corner sharing isosce- les triangles of Fe3+ ions occupying two nonequivalent crystallographic sites. The chains extend innitely along the crystallographic b-axis and are structurally conned from one another via dia- magnetic (AsO4)3- units along the a-axis, and Rb+ cations along the c-axis direction. Neutron diraction measurements indicate the onset of a long range antiferromagnetic order below approxi- mately 25 K. The magnetic structure consists of ferrimagnetic chains which are antiferromagnetically coupled with each other. Within each chain, one of the two Fe sites carries a moment which lies along the b-axis, while the second site bears a canted moment in the opposite direction. Exter- nally applied magnetic eld induces a transition to a ferrimagnetic state, in which the coupling between the sawtooth chains becomes ferromagnetic. Magnetization measurements performed on optically-aligned single crystals reveal evidence for an uncompensated magnetization at low mag- netic elds that could emerge from to a phase-segregated state with ferrimagnetic inclusions or from antiferromagnetic domain walls. The observed magnetic states and the competition between them is expected to arise from strongly frustrated interactions within the sawtooth chains and relatively weak coupling between them.

A synthesis of LiFePO 4 starting from FePO 4 under reducing atmosphere  

Science Journals Connector (OSTI)

A fast and easy way to produce LiFePO 4 starting from FePO 4 used as iron and phosphorus source is proposed. 5% hydrogen is employed as a reducing agent and various compounds containing lithium as lithiation agents. The selected lithiation agents included: LiCl CH 3 COOLi LiOH Li 2 S LiH and Li 2 CO 3 . Solid state synthesis is used for the LiFePO 4 preparation and the so obtained materials are structurally characterized by XRD. The materials are used to fabricate composite electrode and their specific capacity is evaluated by low rate galvanostatic charge/discharge cycles (C/10 rate). Among the various lithium salts the acetate give rise to the LiFePO 4 with the best electrochemical performance. The morphology of this material is further investigated by SEM microscopy and the specific capacity is evaluated as a function of the discharge rate and the cycle number.

The importance of holes in aluminium tris-8-hydroxyquinoline (Alq{sub 3}) devices with Fe and NiFe contacts  

SciTech Connect

To study the dominant charge carrier polarity in aluminium tris-8-hydroxyquinoline (Alq{sub 3}) based spin valves, single Alq{sub 3} layer devices with NiFe, ITO, Fe, and aluminium electrodes were fabricated and characterised by Time of Flight (ToF) and Dark Injection (DI) techniques, yielding a lower hole mobility compared to electron mobility. We compare the mobility measured by DI for the dominant carrier injected from NiFe and Fe electrodes into Alq{sub 3}, to that of holes measured by ToF. This comparison leads us to conclude that the dominant charge carriers in Alq{sub 3} based spin valves with NiFe or Fe electrodes are holes.

Synthesis of Fe-zeolites and Fe-PILC samples and their activity in wet hydrogen peroxide oxidation of p-coumaric acid  

Science Journals Connector (OSTI)

The catalytic wet hydrogen peroxide oxidation of p-coumaric acid was investigated over various Fe-ZSM-5, Fe-BEA and Fe-PILC samples. The catalysts differing in the amount of iron were prepared by the solid state ion exchange method and were caracterized by XRD, BET surface area and Chemical analysis. The oxidation reaction was carried out in a batch reactor at 70°C and atmospheric pressure. A great interest has been focused on the leaching-off of iron. Fe-BEA catalysts were found more effective than Fe-ZSM-5 and Fe-PILC samples. At optimal condition, a solution containing 500 ppm of p-coumaric acid, 10?2M of H2O2 and 0.5 g/l of catalyst was degraded in less than 2h with a significant total organic carbon (TOC) removal. Characterization data were correlated with the activity results.

Scaffolds of magnetically active 3d metals in the valence electron controlled borides Ti{sub 9?x}M{sub 2+x}Ru{sub 18}B{sub 8} (M=Cr–Ni; x=0.5–1): Structutral, electronic and magnetic properties  

SciTech Connect

Polycrystalline samples of the boride series Ti{sub 9?x}M{sub 2+x}Ru{sub 18}B{sub 8} (M=Cr, Co, Mn, Ni) including single crystals of Ti{sub 8}Co{sub 3}Ru{sub 18}B{sub 8} have been prepared by arc-melting the elements. The phases were characterized by powder X-ray diffraction (Rietveld refinement), single-crystal X-ray diffraction (for M=Co), and energy-dispersive X-ray (EDX) analysis. 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 Ru–X (X=B, Ti, Ti/M) bonding interactions are nearly constant throughout the series and responsible for the structural stability of these phases, whereas the M–M and Ru–M 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 Ru–B and Ru–Ti 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=Cr–Ni). • 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.

XAS Characterization of a Nitridoiron(IV) Complex with a Very Short Fe-N Bond  

SciTech Connect

X-ray absorption spectroscopy has been used to characterize the novel nitridoiron(IV) units in two [PhBP{sup R}{sub 3}]Fe(N) complexes (R = iPr and CyCH{sub 2}) and obtain direct spectroscopic evidence for a very short Fe-N distance. The distance of 1.51-1.55 {angstrom} reflects the presence of an Fe{triple_bond}N triple bond in accord with the observed Fe{triple_bond}N vibration observed for one of these species ({nu}{sub FeN} = 1034 cm{sup -1}). This highly covalent bonding interaction results in the appearance of an unusually intense pre-edge peak, whose estimated area of 100(20) units is much larger than those of the related tetrahedral complexes with Fe{sup I}-N{sub 2}-Fe{sup I}, Fe{sup II}-NPh{sub 2}, and Fe{sup III}NAd motifs, and those of recently described six-coordinate Fe{sup V}{triple_bond}N and Fe{sup VI}{triple_bond}N complexes. The observation that the Fe{sup IV}-N distances of two [PhBP{sup R}{sub 3}]Fe(N) complexes are shorter than the Fe{sup IV}-O bond lengths of oxoiron(IV) complexes may be rationalized on the basis of the greater {pi} basicity of the nitrido ligand than the oxo ligand and a lower metal coordination number for the Fe(N) complex.

Theory of Hydride-Proton Transfer (HPT) Carbonyl Reduction by [Os(III)(tpy)(Cl)(NH=CHCH3)(NSAr)  

SciTech Connect

Quantum mechanical analysis reveals that carbonyl reduction of aldehydes and ketones by the imine-based reductant cis-[Os{sup III}(tpy)(Cl)(NH?CHCH{sub 3})(NSAr)] (2), which is accessible by reduction of the analogous nitrile, occurs by hydride-proton transfer (HPT) involving both the imine and sulfilimido ligands. In carbonyl reduction, water or alcohol is necessary to significantly lower the barrier for proton shuttling between ligands. The ?N(H)SAr group activates the carbonyl group through hydrogen bonding while the ?NC(H)CH{sub 3} ligand delivers the hydride.

Modified magnetism within the coherence volume of superconducting FeSeTe  

SciTech Connect

Neutron Scattering is used to probe magnetic interactions as superconductivity develops in opti- mally doped Fe_(1+ )Se_xTe_(1 x). Applying the first moment sum-rule to comprehensive neutron scatter- ing data, we extract the change in magnetic exchange energy [J_(R-R ) S_R S_R ] in the superconducting state referenced to the normal state. Oscillatory changes are observed for Fe-Fe displacements | R| < , where = 1.3(1) nm is the superconducting coherence length. Dominated by a large reduction in the second nearest neighbor exchange energy (-1.2(2) meV/Fe), the overall reduction in magnetic interaction energy is Hmag = 0.31(9) meV/Fe. Comparison to the superconducting condensation energy E_sc = 0.013(1) meV/Fe, which we extract from specific heat data, suggests the modified magnetism we probe drives superconductivity in Fe_(1+ )Se_xTe_(1 x)

Nd1+?Fe4B4 crystallizes with the tetragonal Sm1+?Fe4B4 structure type. It is characterized by two interpenetrating metal substructures with incommensurate translation periods, cNd and cFe. The structure is approximated using a superstructure model of composition Nd19(Fe4B4)17 with c?19cNd?17cFe=66.2(1) A?, and refined from single-crystal x-ray data to a consistency index of R=0.12 (2800 contributing reflections, 139 refined parameters). The results reveal rotational and displacive modulations of the Fe tetrahedra chains, Nd atom strings, and B atom pairs. Their periods can be expressed by Lrot=2Ldis=1/(1/crNd-1/cFe). High-resolution electron microscopy reveals 17-A?-spaced Moiré-type fringes, but no commensurately spaced structure segments.

We use powder neutron diffraction to study the spin and lattice structures of polycrystalline samples of nonsuperconducting PrFeAsO and superconducting PrFeAsO0.85F0.15 and PrFeAsO0.85. We find that PrFeAsO exhibits abrupt structural phase transitions at 153 K followed by static long-range antiferromagnetic order at 127 K. Both the structural distortion and magnetic order are similar to other rare-earth oxypnictides. Electron doping the system with either fluorine or oxygen deficiency suppresses the structural distortion and static long-range antiferromagnetic order, therefore placing these materials into the same class of FeAs-based superconductors.

Effect of tungsten addition on the toughness and hardness of Fe{sub 2}B in wear-resistant Fe-B-C cast alloy  

SciTech Connect

The effects of tungsten additions of 0%, 1.12%, 2.04%, and 3.17% (in wt.%) on the morphology, fracture toughness and micro-hardness of Fe{sub 2}B in Fe-B-C cast alloy were investigated. The results indicate that, with the increase of tungsten addition, the morphology and distribution of Fe{sub 2}B have no change and a new W-containing phase, except the (Fe, W){sub 2}B with a certain tungsten solution, does not form, and that the fracture toughness of Fe{sub 2}B increases first and then decreases, while the hardness increases first and then has a little change. Compared with the fracture toughness (3.8 MPa{center_dot}m{sup 1/2}) of Fe{sub 2}B without tungsten addition, the toughness at 2.04 wt.% tungsten can be improved by about above 80% and achieves about 6.9 MPa{center_dot}m{sup 1/2}, and variation characteristics of hardness and toughness of Fe{sub 2}B were also testified by viewing the indentation marks and cracks on the Fe{sub 2}B, respectively. - Highlights: Black-Right-Pointing-Pointer Poor toughness of Fe2B decreases obviously the wear resistance of the alloy. Black-Right-Pointing-Pointer As W content increases, Fe2B's toughness increases first and then decreases. Black-Right-Pointing-Pointer As W content increases, Fe2B's hardness first increases and then has little change. Black-Right-Pointing-Pointer The toughness at 2.04 % W can be improved by above 80% more than that at 0% W.

AlN/Fe/AlN nanostructures for magnetooptic magnetometry  

SciTech Connect

AlN/Fe/AlN/Cu nanostructures with ultrathin Fe grown by sputtering on Si substrates are evaluated as probes for magnetooptical (MO) mapping of weak currents. They are considered for a laser wavelength of ??=?410?nm (3.02?eV) and operate at oblique light incidence angles, ?{sup (0)}, to enable detection of both in-plane and out-of-plane magnetization. Their performance is evaluated in terms of MO reflected wave electric field amplitudes. The maximal MO amplitudes in AlN/Fe/AlN/Cu are achieved by a proper choice of layer thicknesses. The nanostructures were characterized by MO polar Kerr effect at ?{sup (0)}???5° and longitudinal Kerr effect spectra (?{sup (0)}?=?45°) at photon energies between 1 and 5?eV. The nominal profiles were refined using a model-based analysis of the spectra. Closed form analytical expressions are provided, which are useful in the search for maximal MO amplitudes.

Ferromagnetism at the interfaces of antiferromagnetic FeRh epilayers  

SciTech Connect

The nanoscale magnetic structure of FeRh epilayers has been studied by polarized neutron reflectometry. Epitaxial films with a nominal thickness of 500 {angstrom} were grown on MgO (001) substrates via molecular-beam epitaxy and capped with 20 {angstrom} of MgO. The FeRh films show a clear transition from the antiferromagnetic (AF) state to the ferromagnetic (FM) state with increasing temperature. Surprisingly the films possess a FM moment even at a temperature 80 K below the AF-FM transition temperature of the film. We have quantified the magnitude and spatial extent of this FM moment, which is confined to within {approx}60-80 {angstrom} of the FeRh near the top and bottom interfaces. These interfacial FM layers account for the unusual effects previously observed in films with thickness <100 {angstrom}. Given the delicate energy balance between the AF and FM ground states we suggest a metastable FM state resides near to the interface within an AF matrix. The length scale over which the FM region resides is consistent with the strained regions of the film.

Chemisorption and catalysis by metal clusters. II. Chemisorption of carbon monoxide and of oxygen by supported osmium clusters derived from Os/sub 3/(CO)/sub 12/ and from Os/sub 6/(CO)/sub 18/  

SciTech Connect

Carbon monoxide and oxygen have been chemisorbed at 293 K on the high-nuclearity carbonyl-protected clusters (the various species A) obtained by heating in vacuo to 523 K Os/sub 3/(CO)/sub 12/ or Os/sub 6/(CO)/sub 18/ impregnated on silica, alumina, or titania. The adsorption isotherms have a conventional appearance, but most are composed of a primary and a secondary region. Material adsorbed in the secondary region is removed by evacuation at room temperature whereas that adsorbed in the primary region is removed by evacuation at elevated temperatures. For species A/alumina and the species A/titania the primary region is complete and the secondary region commences when the pressure over the adsorbent is 0.2 Torr. Species A/silica gave no secondary region in oxygen adsorption. Adsorption and subsequent temperature-programmed desorption of (/sup 18/O)CO occurred without any dilution by (/sup 16/O)CO, indicating that ligand-(/sup 16/O)CO and adsorbed-(/sup 18/O)CO do not exchange even at elevated temperatures. The two species A/aluminas catalyzed oxygen isotope exchange at 293 K. From the experimental evidence it is deduced that carbon monoxide and oxygen each adsorbs molecularly in both the primary and the secondary regions. In the primary region carbon monoxide adsorption occurs at osmium sites on the cluster framework, whereas in the secondary region it occurs at ligand-carbon bonded to osmium. For oxygen, adsorption in the primary region is again at osmium sites on the cluster framework but that in the secondary region is at osmium sites of the cluster framework suitably modified as a result of the support-cluster interaction.

Tunneling conductance studies in the ion-beam sputtered CoFe/Mg/MgO/NiFe magnetic tunnel junctions  

SciTech Connect

Magnetic tunnel junctions consisting of CoFe(10 nm)/Mg(1 nm)/MgO(3.5 nm)/NiFe(10 nm) are grown at room temperature using dual ion beam sputtering via in-situ shadow masking. The effective barrier thickness and average barrier height are estimated to be 3.5 nm (2.9 nm) and 0.69 eV (1.09 eV) at 290 K (70 K), respectively. The tunnel magnetoresistance value of 0.2 % and 2.3 % was observed at 290 K and 60 K, respectively. The temperature dependence of tunneling conductance revealed the presence of localized states present within the forbidden gap of the MgO barrier leading to finite inelastic spin independent tunneling contributions, which degrade the TMR value.

Nano and picosecond magnetization dynamics of weakly coupled CoFe/Cr/NiFe trilayers studied by a multitechnique approach  

Science Journals Connector (OSTI)

We present results on the magnetization dynamics in heterostructures of the CoFe/Cr/NiFe type. We have employed a combination of different layer-selective methods covering a broad range from quasistatic hysteresis measurements by x-ray magnetic circular dichroism (XMCD), over time-resolved photoemission electron microscopy (PEEM) at subnanosecond timescales to high-frequency ferromagnetic resonance (FMR) experiments. With increasing driving frequency, we found a different influence of the coupling between the two ferromagnetic layers on the dynamic behavior. Employing the spatial resolution of the PEEM method, we have been able to discern various dynamic responses in different regions of the sample that could be attributed to magnetodynamic processes with a different degree of coupling. In conjunction with the complementary FMR and XMCD measurements, we attribute the inhomogeneous influence of interlayer coupling to a shift from domain-wall-motion-dominated dynamics at low frequencies to precession-dominated dynamics at higher frequencies.

SIMS zircon U–Pb and molybdenite Re–Os geochronology, Hf isotope, and whole-rock geochemistry of the Wunugetushan porphyry Cu–Mo deposit and granitoids in NE China and their geological significance  

Science Journals Connector (OSTI)

Abstract The geodynamic setting of magmatic rocks and geodynamic mechanism of Cu–Mo–Fe–Sn–Pb–Zn–Ag polymetallic mineralization in northeastern (NE) China are attracting increasing attention. This study explores these issues by providing SIMS zircon U–Pb dating, whole-rock geochemical, Hf isotopic data of magmatic rocks, and molybdenite Re–Os dating exposed in the Wunugetushan porphyry Cu–Mo deposit, NE China. This deposit is located in the western part of the Great Xing'an Range, on the southeastern margin of the Mongol–Okhotsk Orogenic Belt. Molybdenite Re–Os and SIMS zircon U–Pb dating of the host monzogranitic porphyry and the wall rock of biotite granite in the Wunugetushan porphyry Cu–Mo deposit indicate that the ore-formation, host porphyry, and wall rock-emplacement occurred at 180.5 ± 2.0 Ma, 180.4 ± 1.4 Ma, and 203.5 ± 1.6 Ma, respectively, and the mineralization of the Wunugetushan porphyry Cu–Mo deposit occurred during the same period as that of the host monzogranitic porphyry. Geochemically, the Wunugetushan granitoids are characterized by strong LREE/HREE fractionation, and pronounced negative Nb, Ta, and Ti anomalies, with slightly negative Eu anomalies (Eu/Eu* = 0.71–0.97) of the host monzogranitic porphyry and pronounced negative Eu anomalies (Eu/Eu* = 0.29–0.32) of the wall rock of biotite granite. In situ Hf isotopic analyses of zircons from the host monzogranitic porphyry and the wall rock of biotite granite yielded ?Hf(t) values ranging from 0.5 to 8.2, and from ? 6.9 to 5.9, respectively. The geochemical and isotopic data for the Wunugetushan granitoids imply that the primary magmas of the host monzogranitic porphyry could have originated by partial melting of a thickened lower crust, with input of mantle components, while the primary magmas of the wall rock of biotite granite could have been derived by partial melting of a thickened lower crust that mixed with ancient crustal materials. Based on the regional geological history, geochemistry of the Wunugetushan granitoids, and new isotopic age data, we suggest that the formation of the Wunugetushan porphyry Cu–Mo deposit was possibly induced in the Early Jurassic during the period of the southeastward subduction of the Mongol–Okhotsk oceanic plate beneath the Erguna Massif.
