Supporting Multidisciplinary Vehicle Analysis Using a Vehicle Reference Architecture Model in SysML  

Science Journals Connector (OSTI)

To develop competitive vehicles with ever increasing complexity, automotive designers need to improve their ability to explore a broad range of system architectures efficiently and effectively. Whereas traditional vehicle systems are based on internal combustion (IC) engines, today's environmentally conscious vehicle manufacturers must consider alternatives to the IC engine- only systems such as hybrid or electric systems. To design a good vehicle, it is necessary to analyze each of these system architectures from a variety of perspectives including performance, fuel economy, or even thermal behavior. Creating all the necessary analysis models for all possible system architectures manually is very time-consuming, expensive, and error-prone. To overcome such challenges, a novel approach has been developed for partly automatically generating subsystem model templates to support the integration of analysis models in a consistent and convenient fashion. The approach starts from a Vehicle Reference Architecture (VRA) model defined in the Systems Modeling Language (OMG SysMLTM). After specialization of this VRA into a specific vehicle program model, this SysML model is automatically transformed into Modelica and Simulink templates for the corresponding analysis models. These templates embody interfaces that fit into a system-level integrated model so that individual subsystem experts can focus on modeling the physical or controls behavior of their particular subsystem without having to worry about subsequent integration issues. The subsystem template models guarantee consistency in the integration phase. The entire approach introduced in this paper is called the Vehicle Architecture Modeling Framework (VAMF), which includes the SysML VRA model, the corresponding analysis templates, and the transformation tools developed to support the approach. Throughout this paper, a specific (realistic but sanitized) vehicle program and a full pedal acceleration analysis test scenario are used as demonstration examples.

TEM studies of Ge nanocrystal formation in PECVD grown  

Science Journals Connector (OSTI)

We investigate the effect of annealing on the Ge nanocrystal formation in multilayered germanosilicateoxide films grown on Si substrates by plasma enhanced chemical vapour deposition (PECVD). The multilayered samples were annealed at temperatures ranging from 750 to 900?C for 5min under nitrogen atmosphere. The onset of formation of Ge nanocrystals, at 750?C, can be observed via high resolution TEM micrographs. The diameters of Ge nanocrystals were observed to be between 5 and 14nm. As the annealing temperature is raised to 850?C, a second layer of Ge nanocrystals forms next to the original precipitation band, positioning itself closer to the substrate SiO2 interface. High resolution cross section TEM images, electron diffraction and electron energy-loss spectroscopy as well as energy-dispersive x-ray analysis (EDAX) data all indicate that Ge nanocrystals are present in each layer.

Enabling direct nanoscale observations of biological reactions with dynamic TEM  

SciTech Connect (OSTI)

Biological processes can occur over a wide range of spatial and temporal scales; from femtoseconds to hours and from angstroms to meters. Although no single experimental method can fully cover this entire phase space, many new biological insights can be expected from a better understanding of the processes that occur on the very fast timescales and very small length scales. In this regard, new instruments that use fast x-ray or electron pulses are now available that are expected to reveal new mechanistic insights for macromolecular protein dynamics. To ensure that any observed conformational change is physiologically relevant and not constrained by three-dimensional crystal packing, it would be preferable for experiments to utilize smaller protein samples such as single particles or two-dimensional crystals that mimic the target proteins native environment. These samples arent typically amenable to x-ray analysis, but transmission electron microscopy has successfully imaged such sample geometries for over 40 years and permits data acquisition using both direct imaging and diffraction modes. While conventional transmission electron microscopes (TEM) have only visualized biological samples with atomic resolution in an arrested or frozen state, the recent development of the dynamic TEM (DTEM) extends electron microscopy capabilities into dynamics. A new 2nd generation DTEM that is currently being constructed has the potential to observe live biological processes with unprecedented spatiotemporal resolution by using pulsed electron packets to probe the sample on the micro- and nanosecond timescale. In addition to the enhanced temporal resolution, the DTEM also operates in the pump-probe regime that can permit visualizing reactions propagating in real-time. This article reviews the experimental parameters necessary for coupling DTEM with in situ liquid microscopy to allow direct imaging of protein conformational dynamics in a fully hydrated environment.

Photoconduction in the Peierls conductor monoclinic TaS$_3$  

E-Print Network [OSTI]

Photoconduction in the monoclinic phase of quasi-one-dimensional conductor TaS$_3$ has been observed at $T quality dependence of both photoconduction and dark conduction at this temperature region has been observed. Together with a similarity of the main features of the photoconduction characteristic of both monoclinic ({\\it m-}TaS$_3$) and orthorhombic ({\\it o-}TaS$_3$) samples the following new peculiarities of photoconduction in {\\it m-}TaS$_3$ were found: 1) the dependence of the activation energy of photoconduction on temperature, $T$, 2) the change of the recombination mechanism from the linear type to the collisional one at low $T$ with a sample quality growth, 3) the existence of a fine structure of the electric-field dependence of photoconduction. Spectral study gives the Peierls energy gap value $2\\Delta ^*= 0.18$~eV.

Measurements of the Threshold Displacement Energy in Ta and Nb  

Science Journals Connector (OSTI)

Changes in the damage rate (residual electrical resistivity per unit electron fluence) were measured as a function of incident electron energy in the range 1.0-2.2 MeV for 0.002-in.-diam Nb and Ta wires. The threshold energies, estimated by simple extrapolation to zero production rates, were 36 eV for Nb and 32 eV for Ta. The resistivity of a Frenkel pair was determined to be about 5.3 ?? cm/at.% for Nb and 1.9 ?? cm/at.% for Ta. The damage production curves for two other bcc metals, Mo and W, are compared with those for Nb and Ta.

Low temperature CVD of TaB/sub 2/  

SciTech Connect (OSTI)

Crystalline TaB/sub 2/ has been deposited using the CVD reaction of TaCl/sub 5/ and B/sub 2/H/sub 6/ in the temperature range of 773-1200/sup 0/K. Thermodynamic calculations have been made which compare the use of both B/sub 2/H/sub 6/ and BCl/sub 3/ as B source gases. The deposits obtained with B/sub 2/H/sub 6/ exhibited extremely small crystal size and contained amorphous B when the deposition temperature was below approx. 873/sup 0/K but were substoichiometric in B above this temperature. Carbon analysis indicated that C may substitute for B and thereby stabilize the diboride structure at high deposition temperatures. Microhardness of the coatings decreased with increasing B/Ta ratio and decreasing crystal size.

A combinatorial investigation of sputtered TaAlC thin films  

Science Journals Connector (OSTI)

Abstract We describe a combinatorial experiment investigating the TaAlC material system, conducted with the aim of determining why the tantalum-containing Mn+1AXn phases have so far proved to be not amenable to thin-film synthesis. Samples were deposited onto (0001) Al2O3 wafers at 850C and characterized by X-ray diffraction wafer maps, scanning electron microscopy, and surface optical scattering. Elemental Ta, the binary phases TaC, Ta2C, and TaAl3, and the ternary phases Ta3Al2C and Ta5Al3C were identified. The morphology, phase composition and preferred orientation of the films deposited were found to be highly sensitive to the Ta fraction of the incident flux during deposition. No MAX phase material was observed, indicating that the Ta-containing MAX phases do not form under the deposition conditions investigated. Explanations associated with inadequate coverage of stochiometries, preferential sputtering, and thermodynamic instability have been ruled out. An explanation based on reduced surface diffusion of Ta during growth is proposed. A substantially higher substrate temperature during deposition is likely to be required to synthesize Ta-containing MAX phases.

Synthesis and Optical Properties of NuTaN2: Potential Solar Cell Applications  

SciTech Connect (OSTI)

Layered CuTaN2 was synthesized by an ion exchange reaction of CuI and NaTaN2 as previously reported. Based on the results of EDX analysis, the Cu:Ta ratio of the CuTaN2 sample was 1:1 within the overall errors when examining powders of +/-10% and no Na was detected. The crystal structure and thermal stability of CuTaN2 was accurately determined by Rietveld analysis of the powder X-ray Diffraction profile and by TGA analysis, respectively. CuTaN2 crystallizes in a rhombohedral structure with space group R-3mH as shown in [figure 1]. CuTaN2 possesses a band gap of 1.53(x) eV, which is in reasonable agreement with density functional theory calculations of Cu containing nitrides. Similar materials may be even better suited for solar cell application.

Magnetotransport measurements of current induced effective fields in Ta/CoFeB/MgO  

SciTech Connect (OSTI)

We evaluate current-induced effective magnetic fields in perpendicularly magnetized Ta/CoFeB/MgO structures from the external magnetic field angle dependence of the Hall resistance. We confirm the presence of two components of effective fields. The dependence of their magnitudes on Ta thickness implies that both components are related to the spin current in Ta layer generated by the spin Hall effect.

Reduced-temperature processing and consolidation of ultra-refractory Ta4HfC5  

SciTech Connect (OSTI)

TaC, HfC, and WC powders were subjected to high-energy milling and hot pressing to produce Ta4HfC5, a composite of Ta(4)HfC5 + 30 vol.% WC, and a composite of Ta4HfC5 + 50 vol.% WC. Sub-micron powders were examined after four different milling intervals prior to hot pressing. XRD was used to verify proper phase formation. SEM, relative density, and hardness measurements were used to examine the resulting phases. Hot pressed compacts of Ta4HfC5 showed densification as high as 98.6% along with Vickers hardness values of 21.4 GPa. Similarly, Ta4HfC5 + 30 vol.% WC exhibited 99% densification with a Vickers hardness of 22.5 GPa. These levels of densification were achieved at 1500 degrees C, which is lower than any previously reported sintering temperature for Ta4HfC5. Microhardness values measured in this study were higher than those previously reported for Ta4HfC5. The WC additions to Ta4HfC5 were found to improve densification and increase microhardness.

Geology of the Western Part of Los Alamos National Laboratory (TA-3 to TA-16), Rio Grande Rift, New Mexico  

SciTech Connect (OSTI)

We present data that elucidate the stratigraphy, geomorphology, and structure in the western part of Los Alamos National Laboratory between Technical Areas 3 and 16 (TA-3 and TA-16). Data include those gathered by geologic mapping of surficial, post-Bandelier Tuff strata, conventional and high-precision geologic mapping and geochemical analysis of cooling units within the Bandelier Tuff, logging of boreholes and a gas pipeline trench, and structural analysis using profiles, cross sections, structure contour maps, and stereographic projections. This work contributes to an improved understanding of the paleoseismic and geomorphic history of the area, which will aid in future seismic hazard evaluations and other investigations. The study area lies at the base of the main, 120-m (400-ft) high escarpment formed by the Pajarito fault, an active fault of the Rio Grande rift that bounds Los Alamos National Laboratory on the west. Subsidiary fracturing, faulting, and folding associated with the Pajarito fault zone extends at least 1,500 m (5,000 ft) to the east of the main Pajarito fault escarpment. Stratigraphic units in the study area include upper units of the Tshirege Member of the early Pleistocene Bandelier Tuff, early Pleistocene alluvial fan deposits that predate incision of canyons on this part of the Pajarito Plateau, and younger Pleistocene and Holocene alluvium and colluvium that postdate drainage incision. We discriminate four sets of structures in the area between TA-3 and TA-16: (a) north-striking faults and folds that mark the main zone of deformation, including a graben in the central part of the study area; (b) north-northwest-striking fractures and rare faults that bound the eastern side of the principal zone of deformation and may be the surface expression of deep-seated faulting; (c) rare northeast-striking structures near the northern limit of the area associated with the southern end of the Rendija Canyon fault; and (d) several small east-west-striking faults. We consider all structures to be Quaternary in that they postdate the Tshirege Member (1.22 million years old) of the Bandelier Tuff. Older mesa-top alluvial deposits (Qoal), which may have a large age range but are probably in part about 1.13 million years old, are clearly faulted or deformed by many structures. At two localities, younger alluvial units (Qfo and Qfi) appear to be truncated by faults, but field relations are obscure, and we cannot confirm the presence of fault contacts. The youngest known faulting in the study area occurred in Holocene time on a down-to-the-west fault, recently trenched at the site of a new LANL Emergency Operations Center (Reneau et al. 2002).

SANS and TEM studies of carbide precipitation and creep damage in type 304 stainless steel  

SciTech Connect (OSTI)

Small-angle neutron scattering (SANS) and transmission electron microscopy (TEM) studies were performed to characterize the carbide (M/sub 23/C/sub 6/) precipitation and creep damage induced in type 304 stainless steel in the primary creep stage. The size distribution of matrix carbides evaluated from SANS analyses was consistent with TEM data, and the expected accelerated kinetics of precipitation under applied stress was confirmed. Additional SANS measurements after the postcreep solution annealing were made in order to differentiate cavities from the carbides. Potential advantages and difficulties associated with characterization of creep-induced cavitation by the SANS techniques are discussed.

Physical and chemical characterization of combinatorial metal gate electrode Ta-C-N library film  

SciTech Connect (OSTI)

This paper reports comprehensive structural and chemical analyses for the combinatorial Ta-C-N/HfO{sub 2} system, crucial data for understanding the electrical properties of Ta-C-N/HfO{sub 2}. Combinatorial Ta-C-N 'library' (composition spread) films were deposited by magnetron sputtering. Electron probe wavelength dispersive spectroscopy and x-ray fluorescence-yield near-edge spectroscopy were used to quantitatively determine the composition across these films. Scanning x-ray microdiffractometry determined that a solid solution of Ta(C,N){sub x} forms and extends to compositions (0.3<=Ta<=0.5 and 0.57<=Ta<=0.67) that were previously unknown. The thermal stability of the Ta-C-N/HfO{sub 2} library was studied using high resolution transmission electron microscopy, which shows Ta-C-N/HfO{sub 2}/SiO{sub 2}/Si exhibiting good thermal stability up to 950 deg. C.

Chemical Concentrations in Field Mice from Open-Detonation Firing Sites TA-36 Minie and TA-39 Point 6 at Los Alamos National Laboratory  

SciTech Connect (OSTI)

Field mice (mostly Peromyscus spp.) were collected at two open-detonation (high explosive) firing sites - Minie at Technical Area (TA) 36 and Point 6 at TA-39 - at Los Alamos National Laboratory in August of 2010 and in February of 2011 for chemical analysis. Samples of whole body field mice from both sites were analyzed for target analyte list elements (mostly metals), dioxin/furans, polychlorinated biphenyl congeners, high explosives, and perchlorate. In addition, uranium isotopes were analyzed in a composite sample collected from TA-36 Minie. In general, all constituents, with the exception of lead at TA-39 Point 6, in whole body field mice samples collected from these two open-detonation firing sites were either not detected or they were detected below regional statistical reference levels (99% confidence level), biota dose screening levels, and/or soil ecological chemical screening levels. The amount of lead in field mice tissue collected from TA-39 Point 6 was higher than regional background, and some lead levels in the soil were higher than the ecological screening level for the field mouse; however, these levels are not expected to affect the viability of the populations over the site as a whole.

Influence of shockwave obliquity on deformation twin formation in Ta  

SciTech Connect (OSTI)

Energetic loading subjects a material to a 'Taylor wave' (triangular wave) loading profile that experiences an evolving balance of hydrostatic (spherical) and deviatoric stresses. While much has been learned over the past five decades concerning the propensity of deformation twinning in samples shockloaded using 'square-topped' profiles as a function of peak stress, achieved most commonly via flyer plate loading, less is known concerning twinning propensity during non-I-dimensional sweeping detonation wave loading. Systematic small-scale energetically-driven shock loading experiments were conducted on Ta samples shock loaded with PEFN that was edge detonated. Deformation twinning was quantified in post-mortem samples as a function of detonation geometry and radial position. In the edge detonated loading geometry examined in this paper, the average volume fraction of deformation twins was observed to drastically increase with increasing shock obliquity. The results of this study are discussed in light of the formation mechanisms of deformation twins, previous literature studies of twinning in shocked materials, and modeling of the effects of shock obliquity on the evolution of the stress tensor during shock loading.

NEPA REVIEW LASO-10-002 CATEGORICAL EXCLUSION PAJARITO ROAD RIGHT-OF-WAY SHIFT AT TA-50 AND TA-55  

Broader source: Energy.gov (indexed) [DOE]

REVIEW REVIEW LASO-10-002 CATEGORICAL EXCLUSION PAJARITO ROAD RIGHT-OF-WAY SHIFT AT TA-50 AND TA-55 1. DESCRIPTION OF PROPOSED ACTION: LANL proposes to shift a segment of Pajarito Road slightly to the south along the edge of Two-Mile Canyon in the vicinity of TA-55. The existing centerline would be moved between 36 feet and 56 feet depending on final designs. This shift would address the need to integrate security requirements related to the Chemistry and Metallurgy Building Replacement Project (CMRR) and the Nuclear Materials Safeguards and Security Upgrades Project (NMSSIJP) - specifically placement of the Perimeter Intrusion Detection, Assessment, and Delay System fence improvements in proximity to Pajarito Road. Pajarito Road is not open to the public and is secured to preclude unauthorized access to the facilities between

Prediction of hexagonal Ta2O5 structure by first-principles calculations  

Science Journals Connector (OSTI)

The undetermined crystal structure of hexagonal Ta2O5 is predicted by the first-principles ultrasoft pseudopotential calculations. Among the several hypothetical structures, the structure which is energetically favorable and consistent with the available experimental data is determined by minimizing the total energy with respect to the volume, the c/a ratio, and the atomic configurations. The predicted structure has the space group of P6/mmm with two formula units in the unit cell. The calculated lattice constants, a=7.191 ? and c=3.831 ?, are in good agreement with the x-ray-diffraction measurement if a is assumed to be twice as large as the measured value due to the extinction rule. The coordination number of O atom to Ta atom is 8 for one Ta atom and 6 for the other three Ta atoms.

Model independent determination of the spin of the {sup 180}Ta naturally occurring isomer  

SciTech Connect (OSTI)

The hyperfine structures of the 33715.27 cm{sup -1} and 33706.47 cm{sup -1} transitions from the ground state of singly ionized Ta have been measured by collinear laser spectroscopy. The structures were found to contain a large second order contribution. From fitting the observed hyperfine components for both {sup 181}Ta and the {sup 180}Ta naturally occurring isomer it was possible to determine the first and second order hyperfine structure coefficients. As no model independent determination of the nuclear spin of the {sup 180}Ta isomer has been performed, fitting was attempted for a range of spins. A clear chi-squared minimum is obtained for a nuclear spin of 9, in agreement with model dependent measurements.

Unique LaTaO[subscript 4] Polymorph for Multiple Energy Applications  

SciTech Connect (OSTI)

Rare-earth niobate and tantalate (RE-Nb/Ta) materials are of considerable interest in environmental and energy-related applications that include phosphors for solid-state lighting, photocatalysts for both contaminant degeneration and H{sub 2} generation, chemically robust hosts for nuclear materials and wastes, and ion conductors for lithium batteries or solid-oxide fuel cells. However, the chemically inert nature limits the synthetic routes available to obtain these materials, which in turn hampers the discovery and development of new RE-Nb/Ta phases. Of the simple orthotantalate, LaTaO{sub 4}, there were three polymorphs known prior. With this paper, we present the structural characterization (from high-resolution X-ray powder diffraction data collected at the APS 11-BM line) of a fourth polymorph. It is obtained only from dehydration of La{sub 2}Ta{sub 2}O{sub 7}(OH){sub 2}, which is in turn synthesized hydrothermally. The structure of the new LaTaO{sub 4} polymorph is distinctive from the others in the arrangement of the alternating La-O polyhedra layers and TaO{sub 6} octahedra layers. Luminescence measurements (Eu-doped) and photocatalysis studies of the new LaTaO{sub 4} polymorph, and comparison to the performance of a previously described LaTaO{sub 4} polymorph reveals enhanced performance of the new polymorph in both applications. This study illustrates the relevance of form-function relationships in solid-state materials, as well as the important role of synthesis in the development of advanced functional materials.

A TEM study of inverse melting in Nb{sub 45}Cr{sub 55}  

SciTech Connect (OSTI)

Inverse melting of bcc Nb{sub 45}Cr{sub 55} is investigated using transmission electron microscopy, high-resolution TEM and electron diffraction. It is shown that the transformation to the amorphous phase initiates at the bcc grain boundaries. The transformation results in an increase in incoherence, evidenced by a loss of bend contours. Some anisotropy is found in the amorphous phase produced by inverse melting, which is associated in HRTEM with preferentially oriented but discontinuous and distorted fringes. The results are consistent with the production of an amorphous phase by inverse melting.

Compositional and Structural Characterization by TEM of Lattice-Mismatched III-V Epilayers  

SciTech Connect (OSTI)

We discuss compositional and structural transmission electron microscopy (TEM) characterization of lattice-mismatched (LMM) III-V epilayers grown on GaAs by metalorganic chemical vapor deposition (MOCVD), with possible applications in high-efficiency multijunction solar cells. In addition to the use of TEM imaging to survey layer thicknesses and defect morphology, our analysis emphasizes the particular methods of energy-dispersive X-ray spectrometry (EDX) and convergent-beam electron diffraction (CBED). Outlined here is a standards-based method for extracting compositions by EDX, which uses principal-component analysis (PCA) [1], combined with the zeta-factor approach of Watanabe and Williams [2]. A procedure is described that uses the coordinates of high-order Laue zone (HOLZ) lines, which are found in the bright-field disks of CBED patterns, to extract composition and strain parameters from embedded epilayers. The majority of the crystal growth for this work was performed at NREL, which has accommodated the development at SDSM&T of the characterization techniques described. However, epilayer deposition capability at SDSM&T has recently been achieved, using a home-built system, which is presently being used to examine new lattice-mismatched structures relevant to photovoltaic technology.

Bixbyite- and anatase-type phases in the system Sc-Ta-O-N  

SciTech Connect (OSTI)

The aim of our study was to modify the basis compound ss-TaON, which crystallizes in the monoclinic baddeleyite-type, by incorporation of appropriate dopant ions, in order to obtain anion-deficient cubic fluorite-type phases, which are of interest as solids with mobile nitrogen ions. For this purpose, scandium-doped tantalum oxide nitrides were prepared by ammonolysis of amorphous oxide precursors. An unexpected variety of phases with different structural features was observed: bixbyite-type phases of general composition Sc{sub x}Ta{sub 1-x}(O,N){sub y} with 0.33{<=}x{<=}1 and 1.7{<=}y{<=}1.9, yellow colored metastable anatase-type phases such as Sc{sub 0.1}Ta{sub 0.9}O{sub 1.2}N{sub 0.8} or Sc{sub 0.15}Ta{sub 0.85}O{sub 1.3}N{sub 0.7} and, additionally, anosovite-type phases Sc{sub x}Ta{sub 3-x}O{sub 2x}N{sub 5-2x} with 0{<=}x{<=}1.05. Selected phases were investigated by UV/vis spectroscopy. Anatase- and anosovite-type compounds show brilliant colors. In the anatase-type phase, a possible anion ordering was examined by theoretical methods. Additionally, energy calculations on phase stability were performed for Sc{sub x}Ta{sub 1-x}O{sub 1+2x}N{sub 1-2x} in the baddeleyite, rutile, and anatase structure types with varying amounts of dopants. - Graphical abstract: New anatase- and bixbyite-type phases obtained as single-phase samples in the system Sc-Ta-O-N.

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

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

Atomic and vacancy ordering in carbide {zeta}-Ta{sub 4}C{sub 3-x} (0.28{<=}x{<=}0.40) and phase equilibria in the Ta-C system  

SciTech Connect (OSTI)

The structure of nonstoichiometric carbide phase {zeta}-Ta{sub 4}C{sub 3-x} formed in the tantalum-carbon (Ta-C) system is studied by X-ray and neutron powder diffraction and metallography. Investigated carbide {zeta}-TaC{sub 0.67} crystallizes in a trigonal (rhombohedral) space group R3-barm with cell parameters a{sub tr}=1.0180(1) nm, {alpha}{sub tr}=17.64 deg. (or a{sub h}=0.31216(2) nm, c{sub h}=3.0058(1) nm in hexagonal axes). The closely packed metal sublattice in carbide {zeta}-Ta{sub 4}C{sub 3-x} consists of alternating blocks where metal atoms are located in the same manner as on the FCC sublattice of the cubic carbide TaC{sub y} and the HCP sublattice of the hexagonal carbide Ta{sub 2}C{sub y}. This metal sublattice represents a transition sublattice between these FCC and HCP sublattices. An ordered distribution of atoms C and structural vacancies in carbide {zeta}-Ta{sub 4}C{sub 3-x} is revealed and the distribution function of atoms C is calculated for nonmetal sublattice sites, on which ordering takes place. It is shown that one long-range order parameter {eta} describes the ordering of {zeta}-carbide and the {eta} value in the investigated {zeta}-Ta{sub 4}C{sub 3-x} phase does not exceed 0.7. Carbide {zeta}-Ta{sub 4}C{sub 3-x} is stable in bulk and powdered states over a wide temperature interval of 300 to {approx}2400 K and has a narrow homogeneity interval from TaC{sub 0.65} to TaC{sub 0.68}. Microhardness of disordered and ordered tantalum carbide TaC{sub y} with the basic B1 structure and trigonal carbide {zeta}-Ta{sub 4}C{sub 3-x} is measured. The phase diagram of the Ta-C system is refined considering data obtained for the {zeta}-Ta{sub 4}C{sub 3-x} phase. - Graphical abstract: Ordered distribution of carbon atoms C and structural vacancies in a unit cell of the trigonal (space group R3-barm) {zeta}-Ta{sub 4}C{sub 3-x} phase.

Observation of thermally etched grain boundaries with the FIB/TEM technique  

SciTech Connect (OSTI)

Thermal etching is a method which is able to reveal and characterize grain boundaries, twins or dislocation structures and determine parameters such as grain boundary energies, surface diffusivities or study phase transformations in steels, intermetallics or ceramic materials. This method relies on the preferential transfer of matter away from grain boundaries on a polished sample during heating at high temperatures in an inert/vacuum atmosphere. The evaporation/diffusion of atoms at high temperatures results in the formation of grooves at the intersections of the planes of grain/twin boundaries with the polished surface. This work describes how the combined use of Focussed Ion Beam and Transmission Electron Microscopy can be used to characterize not only the grooves and their profile with the surface, but also the grain boundary line below the groove, this method being complementary to the commonly used scanning probe techniques. - Highlights: Thermally etched low-carbon steel samples have been characterized by FIB/TEM Grain boundary (GB) lines below the groove have been characterized in this way Absence of ghost traces and large ? angle suggests that GB are not stationary but mobile Observations correlate well with previous works and Mullins' investigations [22].

TEM Characterization of High Burn-up Microstructure of U-7Mo Alloy  

SciTech Connect (OSTI)

As an essential part of global nuclear non-proliferation effort, the RERTR program is developing low enriched U-Mo fuels (< 20% U-235) for use in research and test reactors that currently employ highly enriched uranium fuels. One type of fuel being developed is a dispersion fuel plate comprised of U-7Mo particles dispersed in Al alloy matrix. Recent TEM characterizations of the ATR irradiated U-7Mo dispersion fuel plates include the samples with a local fission densities of 4.5, 5.2, 5.6 and 6.3 E+21 fissions/cm3 and irradiation temperatures of 101-136?C. The development of the irradiated microstructure of the U-7Mo fuel particles consists of fission gas bubble superlattice, large gas bubbles, solid fission product precipitates and their association to the large gas bubbles, grain subdivision to tens or hundreds of nanometer size, collapse of bubble superlattice, and amorphisation. This presentation will describe the observed microstructures specifically focusing on the U-7Mo fuel particles. The impact of the observed microstructure on the fuel performance and the comparison of the relevant features with that of the high burn-up UO2 fuels will be discussed.

Advances in sealed liquid cells for in-situ TEM electrochemial investigation of lithium-ion battery  

Science Journals Connector (OSTI)

Abstract Lithium-ion battery (LIB) technology is currently the most important and promising energy storage technology that has captured the portable electronic market, invaded the power tool equipment market, and penetrated the electric vehicle market. The ever-growing demand for its energy capacity necessitates the understanding of (de)lithiation mechanism on a nanoscale, and thus the development of platforms enabling in-situ electrochemical TEM characterization. Sealed liquid cell (SLC) device has been widely recognized as the most desirable platform, since it allows the introduction of commercial volatile electrolytes into TEM. However, a comprehensive review summarizing the current development of \\{SLCs\\} for in-situ TEM LIB research is missing and in urgent need for its benign development. This review article aims to fill this gap.

SciTech Connect (OSTI)

The surface topography of hydrogenated tetrahedral amorphous carbon (ta-C:H) is critical for various applications such as microelectromechanical devices, magnetic and optical storage devices, and medical implants. The surface topography of ta-C:H films deposited by distributed electron cyclotron resonance plasma from C{sub 2}H{sub 2} gas precursor was investigated. The effects of pressure, together with ion flux and energy, are studied by atomic force microscopy in relation to the structural evolution of the films. The results are compared with the predictions of the Edward-Wilkinson model [Proc. R. Soc. London, Ser. A 44, 1039 (1966)] recently proposed to account for ta-C:H growth and with previous interpretations based on hypersonic shock waves. The random hillocks observed on the smooth surfaces of ta-C:H films deposited at high pressure are thought to result from the interference of high energy shock waves triggered by C{sub 4}H{sub x}{sup +} ions that produce overlapping collision cascades and induce nonlinear effects.

Production ratio of meta-stable isomer in {sup 180}Ta by neutrino-induced reactions  

SciTech Connect (OSTI)

The nucleosynthesis of {sup 180}Ta has remained an unsolved problem and as its origin many nucleosynthesis mechanisms have been proposed. This isotope has the unique feature that the naturally occurring abundance of {sup 180}Ta is actually a meta-stable isomer (half-life of >=10{sup 15} yr), while the ground state is a 1{sup +} unstable state which beta-decays with a half-life of only 8.15 hr. We have made a new time-dependent calculation of {sup 180}Ta meta-stable isomer residual ratio after supernova neutrino-induced reactions. This isomer residual ratio is crucial for understanding the production and survival of this naturally occurring rare isotope. We have constructed a new model under temperature evolution after type II supernova explosion. We include the explicit linking between the isomer and all known excited states and found that the residual ratio is insensitive to astrophysical parameters such as neutrino energy spectrum, explosion energy, decay time constant. We find that the explicit time evolution of the synthesis of {sup 180}Ta avoids the overproduction relative to {sup 138}La for a neutrino process neutrino temperature of 4 MeV.

Excited States of Hf174 from the Decay of Ta174  

Science Journals Connector (OSTI)

The Ta174 activity was produced via the Lu175(?,5n)Ta174 reaction with 66-MeV ? particles from the Crocker Nuclear Laboratory 76-in. isochronous cyclotron. After removal of the F18, the half-lives were deduced by direct measurements. The half-lives of approximately 200 transitions, ranging in energy from 60 to 3000 keV, were identified using Ge(Li) detectors. Over 95% of these lines were assigned to Hf175, Hf174, or Lu173. The half-life of Ta174 was measured to be 71.5 6.5 min. Ge(Li)-Nal coincidence work has been done. The conversion-electron spectrum was first measured using a 3-mm Si(Li) detector with a cooled field-effect transistor and then using the same type of detector plus a magnet.The energies and ? intensities of the 100 transitions attributed to the decay of Ta174 were measured. 32 conversion coefficients were determined. 16 levels with spins and parities are proposed on the basis of ? intensities, coincidence information, and conversion coefficients. 16 more levels are proposed on the basis of energy sums. Spins and parities for four of these levels are suggested. 60 transitions are placed in the decay scheme. A very strong ? feed to the 4+ level of the ground-state rotational band was observed. M1 enhancement in the ? vibrational bands and K-forbidden ? transitions are discussed.

Halogen adsorption on transition-metal surfaces: A case study of Cl on Ta(110)  

Science Journals Connector (OSTI)

Through a series of ab initio calculations, we not only predict the atomic and electronic structure of Cl on Ta(110), but also provide a quantitative basis for understanding a number of controversial questions regarding halogen adsorption on transition-metal surfaces. We demonstrate that a simple dipole layer model accurately describes the unexpected decrease in the work function upon halogen absorption, and that our proposed overlayer structure explains the one-dimensional streaking in the low-energy electron-diffraction pattern of the adsorbate-covered surface. An analysis of the electronic structure suggests that transition metals such as Ta look like simple metals from the point of view of highly electronegative adsorbates such as Cl.

Rotational structures in Ta174 and identical bands in the normal deformation regime  

Science Journals Connector (OSTI)

Ta174 has been studied through the Tm169(9Be,4n) fusion-evaporation reaction in the energy range E(9Be)=4065 MeV. ?- and x-ray in-beam and activity singles spectra, ?-?-t coincidences, and angular-distribution measurements were performed. Four rotational structures have been found and interpreted on the basis of coupling systematics. Mixing ratio signs have been calculated using a semiclassical method and compared with the signs of the angular-distribution coefficients, in order to consolidate configuration assignments. Identical bands, i.e., bands with similar transition energies, have been found in neighboring odd and doubly-odd Ta171-174. This similarity is interpreted here as due to fortuitous compensations between different transverse and collective angular momenta and moments of inertia.

Fe-Cr-Mo based ODS alloys via spark plasma sintering: A combinational characterization study by TEM and APT  

SciTech Connect (OSTI)

Nanoscale oxides play an important role in oxide dispersion strengthened (ODS) alloys for improved high temperature creep resistance and enhanced radiation damage tolerance. In this study, transmission electron microscopy (TEM) and atom probe tomography (APT) were combined to investigate two novel Fe-16Cr-3Mo (wt.%) based ODS alloys. Spark plasma sintering (SPS) was used to consolidate the ODS alloys from powders that were milled with 0.5 wt.% Y2O3 powder only or with Y2O3 powder and 1 wt.% Ti. TEM characterization revealed that both alloys have a bimodal structure of nanometer-size (~ 100 500 nm) and micron-size grains with nanostructured oxide precipitates formed along and close to grain boundaries with diameters ranging from five to tens of nanometers. APT provides further quantitative analyses of the oxide precipitates, and also reveals Mo segregation at grain boundaries next to oxide precipitates. The alloys with and without Ti are compared based on their microstructures.

Duplex Oxide Formation during Transient Oxidation of Cu-5%Ni(001) Investigated by In situ UHV-TEM and XPS  

SciTech Connect (OSTI)

The transient oxidation stage of a model metal alloy thin film was characterized with in situ ultra-high vacuum (UHV) transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and analytic high-resolution TEM. We observed the formations of nanosized NiO and Cu{sub 2}O islands when Cu-5a5%Ni(100) was exposed to oxygen partial pressure, pO{sub 2} = 1 x 10{sup -4} Torr and various temperatures in situ. At 350 C epitaxial Cu{sub 2}O islands formed initially and then NiO islands appeared on the surface of the Cu{sub 2}O island, whereas at 750 C NiO appeared first. XPS and TEM was used to reveal a sequential formation of NiO and then Cu{sub 2}O islands at 550 C. The temperature-dependant oxide selection may be due to an increase of the diffusivity of Ni in Cu with increasing temperature.

A TEM quantitative evaluation of strengthening in an Mg-RE alloy reinforced with SiC  

SciTech Connect (OSTI)

Magnesium alloys containing rare earth elements are known to have high specific strength, good creep and corrosion resistance up to 523 K. The addition of SiC ceramic particles strengthens the metal matrix composite resulting in better wear and creep resistance while maintaining good machinability. The role of the reinforcement particles in enhancing strength can be quantitatively evaluated using transmission electron microscopy (TEM). This paper presents a quantitative evaluation of the different strengthening contributions, determined through TEM inspections, in an SiC Mg-RE composite alloy containing yttrium, neodymium, gadolinium and dysprosium. Compression tests at temperatures ranging between 290 and 573 K were carried out. The microstructure strengthening mechanism was studied for all the compression conditions. Strengthening was compared to the mechanical results and the way the different contributions were combined is also discussed and justified. - Research Highlights: {yields} TEM yield strengthening terms evaluation on a Mg-RE SiC alloy. {yields} The evaluation has been extended to different compression temperature conditions. {yields} Linear and Quadratic sum has been proposed and validated. {yields} Hall-Petch was found to be the most prominent strengthening contributions.

Science Journals Connector (OSTI)

Differential cross sections of neutral pions emitted in Ta181+Au197 collisions at a beam energy of 39.5A MeV have been measured with the two-arm photon spectrometer (TAPS). The kinetic energy and transverse momentum spectra of neutral pions cannot be properly described in the framework of the thermal model, nor when the reabsorption of pions is accounted for in a phenomenological model. However, high energy and high momentum tails of the pion spectra can be well fitted through thermal distributions with unexpectedly soft temperature parameters below 10 MeV.

We apply the model to some recent data of projectile fragmentation of Ni on Ta and Be at beam energy 140 MeV/nucleon and some older data of Xe on Al at beam energy 790 MeV/nucleon. Reasonable values of cross-sections for various composites populated in the reactions are obtained.

The effect of Ta on the magnetic thickness of permalloy (Ni{sub 81}Fe{sub 19}) films  

SciTech Connect (OSTI)

The effect of Ta and Ta/Cu seed layers, and Ta and Cu cap layers on the effective magnetic thickness of ultrathin permalloy (Ni{sub 81}Fe{sub 19}) was investigated for MRAM applications. The films were deposited by Ion Beam Deposition. The magnetic moment of each as-deposited permalloy film was measured using a B-H looper and a SQUID magnetometer. The films were further annealed at either 525 K for 1/2 h or 600 K for 1 h to study the effect of thermally driven interdiffusion on the magnetic moment of the permalloy film. Our theoretical calculations showed that the presence of 12% intermixing at the interface reduces the Ni moments to zero. Experimentally, it was shown that the tantalum rather than the copper interfaces are primarily responsible for the magnetically dead layers. The Ta seed layer interface produces a loss of moment equivalent to a magnetically dead layer of thickness 0.6{+-}0.2 nm. The Ta metal in the cap layer results in a loss of moment equivalent to a dead layer of thickness 1.0{+-}0.2 nm. Upon annealing, thermally driven interdiffusion is concluded to have a strong effect on the Ta(seed)/ Ni{sub 81}Fe{sub 19} as-deposited interface, based on the doubling of the magnetically dead layer to 1.2{+-}0.2 nm. The Ni{sub 81}Fe{sub 19}/Ta(cap) as-deposited interface slightly increases its equivalent magnetically dead layer upon annealing to 1.2{+-}0.2 nm. As-deposited interfaces of Ta(seed)/permalloy and permalloy/Ta(cap) are not chemically equivalent and result in different magnetically dead layers, whereas after annealing to 600 K both interfaces attain comparable intermixing and magnetically dead layers. It was also shown that a half-hour anneal at the lower 525 K annealing temperature, which is closer to the actual processing temperature, results in only slight increase of the magnetically dead layer at both interfaces.

Specificity and cooperativity at [beta]-lactamase position 104 in TEM-1/BLIP and SHV-1/BLIP interactions  

SciTech Connect (OSTI)

Establishing a quantitative understanding of the determinants of affinity in protein-protein interactions remains challenging. For example, TEM-1/{beta}-lactamase inhibitor protein (BLIP) and SHV-1/BLIP are homologous {beta}-lactamase/{beta}-lactamase inhibitor protein complexes with disparate K{sub d} values (3 nM and 2 {mu}M, respectively), and a single substitution, D104E in SHV-1, results in a 1000-fold enhancement in binding affinity. In TEM-1, E104 participates in a salt bridge with BLIP K74, whereas the corresponding SHV-1 D104 does not in the wild type SHV-1/BLIP co-structure. Here, we present a 1.6 {angstrom} crystal structure of the SHV-1 D104E/BLIP complex that demonstrates that this point mutation restores this salt bridge. Additionally, mutation of a neighboring residue, BLIP E73M, results in salt bridge formation between SHV-1 D104 and BLIP K74 and a 400-fold increase in binding affinity. To understand how this salt bridge contributes to complex affinity, the cooperativity between the E/K or D/K salt bridge pair and a neighboring hot spot residue (BLIP F142) was investigated using double mutant cycle analyses in the background of the E73M mutation. We find that BLIP F142 cooperatively stabilizes both interactions, illustrating how a single mutation at a hot spot position can drive large perturbations in interface stability and specificity through a cooperative interaction network.

Automated measurement of grain orientations and on-line determination of complete deformation systems with a TEM  

SciTech Connect (OSTI)

An automated computer technique for the indexing of spot or transmission Kikuchi patterns from any crystal structure has been developed. The patterns are recorded from the fluorescence screen of a PHILIPS EM 430 TEM with an integrating, Peltier cooled CCD camera (PULNIX TM 860N) through a window from outside by replacing the focusing binocular. The frame-grabber board PCLL2 (SPINDLER & HOYER) has a resolution of 8 bit which corresponds to 256 grey levels. To reduce the high range of image contrast, a circular continuous density filter is positioned directly in front of the camera lens. A system for image orientation microscopy requires the automated shift of the beam position on the sample, or alternatively a translation movement of the sample with respect to the stationary primary beam, in well defined steps after each orientation measurement. In the EM 430 TEM the built-in scanning unit is simply used to move the electron probe across the sample. The shift is controlled by the computer through a digital-to-analog converter interface. 6 refs., 2 figs.

Crystal structure determination of the oxynitride Sr{sub 2}TaO{sub 3}N  

SciTech Connect (OSTI)

The crystal structure of the strontium tantalum oxynitride Sr{sub 2}TaO{sub 3}N has been resolved by Rietveld refinement using time-of-flight neutron powder diffraction data. The structure is of the K{sub 2}NiF{sub 4} type with a partially ordered anion sublattice (tetragonal, I4/mmm, a = 4.04127(3) {angstrom}, c = 12.6073(2) {angstrom}, c/a = 3.120, Z = 2). The tantalum atoms are at the center of TaO{sub 2}(O, N){sub 4} octahedra built up from two oxygen atoms at the apexes and four (N + O) atoms statistically forming the median plane.

Effect of water vapor/hydrogen environments on niobium, B-66 niobium alloy, tantalum, and Ta-10W alloy  

SciTech Connect (OSTI)

In this paper, the results of an experimental investigation of the effect of water vapor/hydrogen environments on the mechanical properties of niobium, B-66 niobium alloy, tantalum, and Ta-10W alloy are presented. Tensile tests were conducted on specimens of these materials in water vapor/hydrogen mixture ratios of 1 and 3. The water vapor/hydrogen environment caused strength reductions on tantalum and Ta-10W and ductility reductions on all four materials. The degree and causes of embrittlement were a complex function of temperature.

Polycrystalline oxides formation during transient oxidation of (001) Cu-Ni binary alloys studied by in situ TEM and XRD.  

SciTech Connect (OSTI)

The nucleation and growth of Cu{sub 2}O and NiO islands due to oxidation of Cu{sub x}Ni{sub 1-x} (001) films were monitored, at various temperatures, by in situ ultra-high vacuum (UHV) transmission electron microscopy (TEM) and in situ synchrotron X-ray diffraction (XRD). In remarkable contrast to our previous observations of Cu and Cu-Au oxidation, irregular-shaped polycrystalline oxide islands formed with respect to the Cu-Ni alloy film, and an unusual second oxide nucleation stage was noted. In situ XRD experiments revealed that NiO formed first epitaxially, then other orientations appeared, and finally polycrystalline Cu{sub 2}O developed as the oxidation pressure was increased. The segregation of Ni and Cu towards or away, respectively, from the alloy surface during oxidation could disrupt the surface and cause polycrystalline oxide formation.

TEM and x-ray investigation of single crystal-like zirconia films fabricated by dual ion beam deposition  

SciTech Connect (OSTI)

Single crystal-like yttria-stabilized zirconia (YSZ) thin films have been deposited on amorphous quartz, polycrystalline zirconia, single crystal Si, and Hastelloy substrates using dual ion beam deposition (IBAD). These films are highly crystallographically aligned both normal to and within the film plane. The films are deposited at low substrate temperatures (< 200 C), and the film orientation is substrate independent. 0--20 X-ray diffraction, X-ray rocking curves, X-ray pole figures and X-ray phi scans are used to evaluate the film structure. High resolution cross-sectional TEM is used to examine the evolution of crystallographic film alignment on an amorphous quartz substrate. The data suggest that the evolution of biaxial alignment is nucleation controlled under these conditions.

Complete genome sequence of Tolumonas auensis type strain (TA 4T)  

SciTech Connect (OSTI)

Tolumonas auensis Fischer-Romero et al. 1996 is currently the only validly named species of the genus Tolumonas in the family Aeromonadaceae. The strain is of interest because of its ability to produce toluene from phenylalanine and other phenyl precursors, as well as phenol from tyrosine. This is of interest because toluene is normally considered to be a tracer of anthropogenic pollution in lakes, but T. auensis represents a biogenic source of toluene. Oth- er than Aeromonas hydrophila subsp. hydrophila, T. auensis strain TA 4T is the only other member in the family Aeromonadaceae with a completely sequenced type-strain genome. The 3,471,292 bp chromosome with a total of 3,288 protein-coding and 116 RNA genes was sequenced as part of the DOE Joint Genome Institute Program JBEI 2008.

Preparation and characterisation of isotopically enriched Ta$_2$O$_5$ targets for nuclear astrophysics studies  

E-Print Network [OSTI]

The direct measurement of reaction cross sections at astrophysical energies often requires the use of solid targets of known thickness, isotopic composition, and stoichiometry that are able to withstand high beam currents for extended periods of time. Here, we report on the production and characterisation of isotopically enriched Ta$_2$O$_5$ targets for the study of proton-induced reactions at the Laboratory for Underground Nuclear Astrophysics facility of the Laboratori Nazionali del Gran Sasso. The targets were prepared by anodisation of tantalum backings in enriched water (up to 66% in $^{17}$O and up to 96% in $^{18}$O). Special care was devoted to minimising the presence of any contaminants that could induce unwanted background reactions with the beam in the energy region of astrophysical interest. Results from target characterisation measurements are reported, and the conclusions for proton capture measurements with these targets are drawn.

In Situ Laser Crystallization of Amorphous Silicon for TFT Applications: Controlled Ultrafast Studies in the Dynamic TEM  

SciTech Connect (OSTI)

An in situ method for studying the role of laser energy on the microstructural evolution of polycrystalline Si is presented. By monitoring both laser energy and microstructural evolution simultaneously in the dynamic transmission electron microscope, information on grain size and defect concentration can be correlated directly with processing conditions. This proof of principle study provides fundamental scientific information on the crystallization process that has technological importance for the development of thin film transistors. In conclusion, we successfully developed a method for studying UV laser processing of Si films in situ on nanosecond time scales, with ultimate implications for TFT application improvements. In addition to grain size distribution as a function of laser energy density, we found that grain size scaled with laser energy in general. We showed that nanosecond time resolution allowed us to see the nucleation and growth front during processing, which will help further the understanding of microstructural evolution of poly-Si films for electronic applications. Future studies, coupled with high resolution TEM, will be performed to study grain boundary migration, intergranular defects, and grain size distribution with respect to laser energy and adsorption depth.

Laboratory analysis of soil hydraulic properties of TA-49 soil samples. Volume I: Report summary  

SciTech Connect (OSTI)

The Hydrologic Testing Laboratory at Daniel B. Stephens & Associates, Inc. (DBS&A) has completed laboratory tests on TA-49 soil samples as specified by Mr. Daniel A. James and summarized in Table 1. Tables 2 through 12 give the results of the specified analyses. Raw laboratory data and graphical plots of data (where appropriate) are contained in Appendices A through K. Appendix L lists the methods used in these analyses. A detailed description of each method is available upon request. Thermal properties were calculated using methods reviewed by Campbell and covered in more detail in Appendix K. Typically, soil thermal conductivities are determined using empirical fitting parameters (five in this case), Some assumptions are also made in the equations used to reduce the raw data. In addition to the requested thermal property measurements, calculated values are also presented as the best available internal check on data quality. For both thermal conductivities and specific heats, calculated and measured values are consistent and the functions often cross. Interestingly, measured thermal conductivities tend to be higher than calculated thermal conductivities around typically encountered in situ moisture contents ({plus_minus}5 percent). While we do not venture an explanation of the difference, sensitivity testing of any problem requiring nonisothermal modeling across this range is in order.

Progress in Studies of Electron-Cloud-Induced Optics Distortions at CesrTA  

SciTech Connect (OSTI)

The Cornell Electron Storage Ring Test Accelerator (CesrTA) program has included extensive measurements of coherent betatron tune shifts for a variety of electron and positron beam energies, bunch population levels, and bunch train configurations. The tune shifts have been shown to result primarily from the interaction of the beam with the space-charge field of the beam-induced low-energy electron cloud in the vacuum chamber. Comparison to several advanced electron cloud simulation codes has allowed determination of the sensitivity of these measurements to physical parameters characterizing the synchrotron radiation flux, the production of photo-electrons on the vacuum chamber wall, the beam emittance, lattice optics, and the secondary-electron yield model. We report on progress in understanding the cloud buildup and decay mechanisms in magnetic fields and in field-free regions, addressing quantitatively the precise determination of the physical parameters of the modeling. Validation of these models will serve as essential input in the design of damping rings for future high-energy linear colliders.

Study of possible systematics in the L*X - Ta* correlation of Gamma Ray Bursts  

E-Print Network [OSTI]

Gamma Ray Bursts (GRBs) are the most energetic sources in the universe and among the farthest known astrophysical sources. These features make them appealing candidates as standard candles for cosmological applications so that studying the physical mechanisms for the origin of the emission and correlations among their observable properties is an interesting task. We consider here the luminosity L*X - break time Ta* (hereafter LT) correlation and investigate whether there are systematics induced by selection effects or redshift dependent calibra- tion. We perform this analysis both for the full sample of 77 GRBs with known redshift and for the subsample of GRBs having canonical X-ray light curves, hereafter called U0095 sample. We do not find any systematic bias thus con- firming the existence of physical GRB subclasses revealed by tight correlations of their afterglow properties. Furthermore, we study the possibility of applying the LT correlation as a redshift estimator both for the full distribution and for the canonical lightcurves. The large uncertainties and the non negligible intrin- sic scatter make the results not so encouraging, but there are nevertheless some hints motivating a further analysis with an increased U0095 sample.

New Results on e+e- Line Emission in U+Ta Collisions  

E-Print Network [OSTI]

We present new results obtained from a series of follow-up e+e- coincidence measurements in heavy-ion collisions, utilizing an improved experimental set-up at the double-Orange beta-spectrometer of GSI. The collision system U+Ta was reinvestigated in three independent runs at beam energies in the range (6.0-6.4)xA MeV and different target thicknesses, with the objective to reproduce a narrow sum-energy e+e- line at ~635 keV observed previously in this collision system. At improved statistical accuracy, the line could not be found in these new data. For the ''fission'' scenario, an upper limit (1 sigma) on its production probability per collision of 1.3x10^{-8} can be set which has to be compared to the previously reported value of [4.9 +- 0.8 (stat.) +- 1.0 (syst)]x10^{-7}. In the light of the new results, a reanalysis of the old data shows that the continuous part of the spectrum at the line position is significantly higher than previously assumed, thus reducing the production probability of the line by a factor of two and its statistical significance to < 3.4sigma.

A Quasicontinuum Study of Nanovoid Collapse under Uniaxial Loading in Ta  

SciTech Connect (OSTI)

The mechanisms underlying the deformation of nanovoids in Ta single crystals are analyzed when they are subjected to cyclic uniaxial deformation using numerical simulations. Boundary and cell-size effects have been mitigated by means of the Quasicontinuum (QC) method. We have considered {approx} 1 billion-atom systems containing 10.9 nm voids. Two kinds of simulations have been performed, each characterized by a different boundary condition. First, we compress the material along the nominal [0 0 1] direction, resulting in a highly symmetric configuration that results in high stresses. Second, we load the material along the high-index [{bar 4}819] direction to confine plasticity to a single slip system and break the symmetry. We find that the plastic response under these two conditions is strikingly different, the former governed by dislocation loop emission and dipole formation, while the latter is dominated by twinning. We calculate the irreversible plastic work budget derived from a loading-unloading cycle and identify the most relevant yield points. These calculations represent the first fully three-dimensional, fully non-local simulations of any body-centered cubic metal using QC.

Multi-quasiparticle structures up to spin $\\sim{44}\\hbar$ in the odd-odd nucleus $^{168}$Ta  

E-Print Network [OSTI]

High-spin states in the odd-odd nucleus $^{168}$Ta have been populated in the $^{120}$Sn($^{51}$V,3n) reaction. Two multi-quasiparticle structures have been extended significantly from spin $\\sim{20\\hbar}$ to above ${40\\hbar}$. As a result, the first rotational alignment has been fully delineated and a second band crossing has been observed for the first time in this nucleus. Configurations for these strongly-coupled rotational bands are proposed based on signature splitting, $B(M1)/B(E2)$ ratio information, and observed rotation-alignment behavior. Properties of the observed bands in $^{168}$Ta are compared to related structures in the neighboring odd-$Z$, odd-$N$, and odd-odd nuclei and are discussed within the framework of the cranked shell model.

The effect of Ta doping in polycrystalline TiO{sub x} and the associated thin film transistor properties  

SciTech Connect (OSTI)

Tantalum (Ta) is suggested to act as an electron donor and crystal phase stabilizer in titanium oxide (TiO{sub x}). A transition occurs from an amorphous state to a crystalline phase at an annealing temperature above 300?C in a vacuum ambient. As the annealing temperature increases from 300?C to 450?C, the mobility increases drastically from 0.07 cm{sup 2}/Vs to 0.61 cm{sup 2}/Vs. The remarkable enhancement of thin film transistor performance is suggested to be due to the splitting of Ti 3d band orbitals as well as the increase in Ta{sup 5+} ions that can act as electron donors.

Stability analysis of NbTi-Ta-based high field conductor cooled by pool boiling below 4 K  

SciTech Connect (OSTI)

Stability analysis has been performed for cabled NbTi-Ta-based superconductors intended for the high field (12 T) toroidal field coils for a large scale tokamak device such as ETF. Ternary NbTi-Ta was selected as the superconductor because of its superior critical current density at high field as compared to the binary alloy NbTi. The operating temperature was chosen to be 2.5 K or below to optimize the performance of the superconductor. A cabled conductor was selected to minimize the pulsed field losses. The conductor is cooled by pool boiling in a subcooled (approx. 2.5 K, 0.25 atm) bath, or in a superfluid helium (He-II) bath (approx. 1.8 K, 0.02 atm). The analysis was based on numerically simulating the evolution of a normal zone in the conductor. Appropriate superconductor properties and heat transfer characteristics were utilized in the simulation.

Total fission cross section of {sup 181}Ta and {sup 208}Pb induced by protons at relativistic energies  

SciTech Connect (OSTI)

Total fission cross section induced by protons in {sup 181}Ta and {sup 208}Pb at energies in the range of 300 to 1000 A MeV have been measured at GSI (Germany) using the inverse kinematics technique. A dedicated setup with high efficiency made it possible to determine these cross sections with high accuracy. The new data seed light in the controversial results obtained so far and contribute to the understanding of the fission process at high excitation energies. (authors)

Unusual crystallographic structure and its fluctuation of indium nanoparticles as-deposited and observed with HRTEM using the UHV-DC-TEM system  

Science Journals Connector (OSTI)

A UHV-DC-TEM system was developed for direct transportation of samples between an ultra-high vacuum deposition chamber (UHV-DC) and a UHV transmission electron microscope (UHV-TEM). Indium nanoparticles have been deposited onto Si(110) TEM samples at room temperature in UHV-DC and observed in UHV-TEM with high resolution transmission electron microscopy (HRTEM). Freshly made indium nanoparticles were found to be single, twinned, pseudo-twinned crystals and decahedral multiply-twinned particles (MTPs) with their size in the range 815nm. The structure of single crystalline indium nanoparticles is body-centered tetragonal (bct), which is the same as that of bulk indium. In addition to the usual {011} type twins for bct structure, a pseudo-twin was observed to have an orientation relationship as [111]A//[100]B and (101?)A//(01?1?)B. The structure of MTP indium is complicated because of the co-existence of bct and fcc structures within one nanocrystal. The structure fluctuation process has been examined using a video recorder with time scale down to 1/60s. No complete liquid state was seen during this fluctuation.

An Ultrahigh Resolution Structure of TEM-1 beta-Lactamase Suggests a Role for Glu166 as the General Base in Acylation  

SciTech Connect (OSTI)

Although TEM-1 {beta}-lactamase is among the best studied enzymes, its acylation mechanism remains controversial. To investigate this problem, the structure of TEM-1 in complex with an acylation transition-state analogue was determined at ultrahigh resolution (0.85 {angstrom}) by X-ray crystallography. The quality of the data was such as to allow for refinement to an R-factor of 9.1% and an R{sub free} of 11.2%. In the resulting structure, the electron density features were clear enough to differentiate between single and double bonds in carboxylate groups, to identify multiple conformations that are occupied by residues and loops, and to assign 70% of the protons in the protein. Unexpectedly, even at pH 8.0 where the protein was crystallized, the active site residue Glu166 is clearly protonated. This supports the hypothesis that Glu166 is the general base in the acylation half of the reaction cycle. This structure suggests that Glu166 acts through the catalytic water to activate Ser70 for nucleophilic attack on the {beta}-lactam ring of the substrate. The hydrolytic mechanism of class A {beta}-lactamases, such as TEM-1, appears to be symmetrical, as are the serine proteases. Apart from its mechanistic implications, this atomic resolution structure affords an unusually detailed view of the structure, dynamics, and hydrogen-bonding networks of TEM-1, which may be useful for the design of inhibitors against this key antibiotic resistance target.

Quasifission and difference in formation of evaporation residues in the $^{16}$O+$^{184}$W and $^{19}$F+$^{181}$Ta reactions  

E-Print Network [OSTI]

The excitation functions of capture, complete fusion, and evaporation residue formation in the $^{16}$O+$^{184}$W and $^{19}$F+$^{181}$Ta reactions leading to the same $^{200}$Pb compound nucleus has been studied theoretically to explain the experimental data showing more intense yield of evaporation residue in the former reaction in comparison with that in the latter reaction. The observed difference is explained by large capture cross section in the former and by increase of the quasifission contribution to the yield of fission-like fragments in the $^{19}$F+$^{181}$Ta reaction at large excitation energies. The probability of compound nucleus formation in the $^{16}$O+$^{184}$W reaction is larger but compound nuclei formed in both reactions have similar angular momentum ranges at the same excitation energy. The observed decrease of evaporation residue cross section normalized to the fusion cross section in the $^{19}$F+$^{181}$Ta reaction in comparison with the one in the $^{16}$O+$^{184}$W reaction at high excitation energies is explained by the increase of hindrance in the formation of compound nucleus connected with more quick increase of the quasifission contribution in the $^{19}$F induced reaction. The spin distributions of the evaporation residue cross sections for the two reactions are also presented.

Infrared optical properties of amorphous and nanocrystalline Ta{sub 2}O{sub 5} thin films  

SciTech Connect (OSTI)

The optical constants of tantalum pentoxide (Ta{sub 2}O{sub 5}) are determined in a broad spectral region from the visible to the far infrared. Ta{sub 2}O{sub 5} films of various thicknesses from approximately 170 to 1600 nm are deposited using reactive magnetron sputtering on Si substrates. X-ray diffraction shows that the as-deposited films are amorphous, and annealing in air at 800 C results in the formation of nanocrystalline Ta{sub 2}O{sub 5}. Ellipsometry is used to obtain the dispersion in the visible and near-infrared. Two Fourier-transform infrared spectrometers are used to measure the transmittance and reflectance at wavelengths from 1 to 1000 ?m. The surface topography and microstructure of the samples are examined using atomic force microscopy, confocal microscopy, and scanning electron microscopy. Classical Lorentz oscillators are employed to model the absorption bands due to phonons and impurities. A simple model is introduced to account for light scattering in the annealed films, which contain micro-cracks. For the unannealed samples, an effective-medium approximation is used to take into account the adsorbed moisture in the film and a Drude free-electron term is also added to model the broad background absorption.

Low-temperature oriented growth of vanadium dioxide films on CoCrTa metal template on Si and vertical metal-insulator transition  

SciTech Connect (OSTI)

The authors achieved oriented growth of vanadium dioxide (VO{sub 2}) films on CoCrTa metal template grown on an Si substrate. Low-temperature ({approx}250 Degree-Sign C) deposition of VO{sub 2} films using inductively coupled-plasma-assisted sputtering technique realized an abrupt interface between VO{sub 2} and CoCrTa layers, suppressing the oxidation and diffusion of metal components. The films revealed a metal-insulator transition with resistance change of over 2 orders of magnitude. The CoCrTa film, in which Co hexagonal crystalline grains with c-axis orientation were surrounded by segregated Cr and Ta, serves for the oriented growth of VO{sub 2} crystalline film, enabling higher orders of transition in resistance and low voltage switching, even for the vertical (out-of-plane) direction.

The production of {delta}{sup 0}(1232){yields}p{pi}{sup -} resonance is studied in peripheral C+Ta collisions at 4.2A GeV using the 2-m propane bubble chamber exposed at JINR Dubna Synchrophasotron. Using an invariant mass distribution of p{pi}{sup -} pairs and additional kinematical constrains, the mass, width, and kinematical characteristics of {delta}{sup 0} resonance are determined. The ratio of the number of pions originated from {delta}{sup 0} resonance decay to the number of all pions (resonant and nonresonant) is estimated. The analogous ratio for protons is also determined.

Building America Case Study: Ground Source Heat Pump Research, TaC Studios Residence, Atlanta, Georigia (Fact Sheet)  

SciTech Connect (OSTI)

As part of the NAHB Research Center Industry Partnership, Southface partnered with TaC Studios, an Atlanta based architecture firm specializing in residential and light commercial design, on the construction of a new test home in Atlanta, GA in the mixed-humid climate. This home serves as a residence and home office for the firm's owners, as well as a demonstration of their design approach to potential and current clients. Southface believes the home demonstrates current best practices for the mixed-humid climate, including a building envelope featuring advanced air sealing details and low density spray foam insulation, glazing that exceeds ENERGY STAR requirements, and a high performance heating and cooling system. Construction quality and execution was a high priority for TaC Studios and was ensured by a third party review process. Post construction testing showed that the project met stated goals for envelope performance, an air infiltration rate of 2.15 ACH50. The homeowner's wished to further validate whole house energy savings through the project's involvement with Building America and this long-term monitoring effort. As a Building America test home, this home was evaluated to detail whole house energy use, end use loads, and the efficiency and operation of the ground source heat pump and associated systems. Given that the home includes many non-typical end use loads including a home office, pool, landscape water feature, and other luxury features not accounted for in Building America modeling tools, these end uses were separately monitored to determine their impact on overall energy consumption.

Activation cross sections of $\\alpha$-particle induced nuclear reactions on hafnium and deuteron induced nuclear reaction on tantalum: production of $^{178}$W/$^{178m}$Ta generator  

E-Print Network [OSTI]

In the frame of a systematic study of charged particle production routes of medically relevant radionuclei, the excitation function for indirect production of $^{178m}$Ta through $^{nat}$Hf($\\alpha$,xn)$^{178}$W-$^{178m}$Ta nuclear reaction was measured for the first time up to 40 MeV. In parallel, the side reactions $^{nat}$Hf($\\alpha$,x)$^{179,177,176,175}$W, $^{183,182,178g,177,176,175}$Ta, $^{179m,177m,175}$Hf were also assessed. Stacked foil irradiation technique and $\\gamma$-ray spectrometry were used. New experimental cross section data for the $^{nat}$Ta(d,xn)$^{178}$W reaction are also reported up to 40 MeV. The measured excitation functions are compared with the results of the ALICE-IPPE, and EMPIRE nuclear reaction model codes and with the TALYS 1.4 based data in the TENDL-2013 library. The thick target yields were deduced and compared with yields of other charged particle ((p,4n), (d,5n) and ($^3$He,x)) production routes for $^{178}$W.

Regularization strategy for the layered inversion of airborne TEM data: application to VTEM data acquired over the basin of Franceville (Gabon)  

E-Print Network [OSTI]

Airborne transient electromagnetic (TEM) is a cost-effective method to image the distribution of electrical conductivity in the ground. We consider layered earth inversion to interpret large data sets of hundreds of kilometre. Different strategies can be used to solve this inverse problem. This consists in managing the a priori information to avoid the mathematical instability and provide the most plausible model of conductivity in depth. In order to obtain fast and realistic inversion program, we tested three kinds of regularization: two are based on standard Tikhonov procedure which consist in minimizing not only the data misfit function but a balanced optimization function with additional terms constraining the lateral and the vertical smoothness of the conductivity; another kind of regularization is based on reducing the condition number of the kernel by changing the layout of layers before minimizing the data misfit function.

Observation of a Magnetic Modulation of the Lattice Electric-Field Gradient of Fe2+ Substituted in 1T-TaS2  

Science Journals Connector (OSTI)

An unusual temperature dependence of the quadrupole splitting of Fe2+ in 1T-Fe0.1Ta0.9S2 can be understood in terms of a magnetic modulation of the lattice electric-field gradient. This modulation is produced by a strictive interaction between the local lattice environment and the continuous low-spin-high-spin transition of Fe2+. The onset of the charge-density-wave instability can also be observed.

In Situ TEM Investigation of Congruent Phase Transition and Structural Evolution of Nanostructured Silicon/Carbon Anode for Lithium Ion Batteries  

SciTech Connect (OSTI)

It is well known that upon lithiation both crystalline and amorphous Si transform to a armorphous LixSi phase, which subsequently crystallizes to a (Li, Si) crystalline compound, either Li15Si or Li22Si5. Up to date, the detailed atomistic mechanism of this phase transformation, and degradation process in nanostructured Si, are not fully understood. Here, we report the microstructural evolution and phase transformation characteristic of a specially designed amorphous silicon (a-Si) coated carbon nanofiber (CNF) composite during charge/discharge process using in-situ TEM and density function theory molecular dynamic (DFT-MD) calculation. We found that the crystallization of Li15Si4 from amorphous LixSi is a spontaneous, congruent phase transition process without phase separation or large scale atomic motion, which is drastically different from what is expected from a classic nucleation and growth process. The a-Si layer is strongly bonded to the CNF and no spallation or cracking is observed during the early stages of cyclic charge/discharge. Reversible volume expansion/contraction upon charge/discharge is fully accommodated along the radial direction. However, with progressive cycling, damage in the form of surface roughness was gradually accumulated on the coating layer, which is believed to be the mechanism for the eventual capacity fade of the composite anode during long term charge/discharge cycling.

Microaspiration for high-pressure freezing: a new method for ultrastructural preservation of fragile and sparse tissues for TEM and electron tomography  

SciTech Connect (OSTI)

High-pressure freezing is the preferred method to prepare thick biological specimens for ultrastructural studies. However, the advantages obtained by this method often prove unattainable for samples that are difficult to handle during the freezing and substitution protocols. Delicate and sparse samples are difficult to manipulate and maintain intact throughout the sequence of freezing, infiltration, embedding, and final orientation for sectioning and subsequent TEM imaging. An established approach to surmount these difficulties is the use of cellulose microdialysis tubing to transport the sample. With an inner diameter of 200 micrometers, the tubing protects small and fragile samples within the thickness constraints of high-pressure freezing, and the tube ends can be sealed to avoid loss of sample. Importantly, the transparency of the tubing allows optical study of the specimen at different steps in the process. Here, we describe the use of a micromanipulator and microinjection apparatus to handle and position delicate specimens within the tubing. We report two biologically significant examples that benefit from this approach, 3D cultures of mammary epithelial cells and cochlear outer hair cells. We illustrate the potential for correlative light and electron microscopy as well as electron tomography.

Superconductivity in amorphous T5T9 transition-metal alloys (T5=Nb,Ta;T9=Rh,Ir)  

Science Journals Connector (OSTI)

The superconducting transition temperature Tc has been measured for amorphous T5T9 alloys (where T5=Nb or Ta , T9=Rb or Ir ) as a function of composition. Nb and Ta dominated the Tc behavior with Tc for Nb alloys ? 4.8-5.1 K and Tc for Ta alloys ? 3.1-3.3 K. Changing the average group number by varying the T5T9 ratio had little effect on Tc within the ? 10 at.% range of composition in which the amorphous alloys form. Tc decreased approximately linearly with x for (Nb1-xTax)55Rh45 and (Nb1-xTax)55Ir45. The electrical resistivity ?n and the upper critical field Bc2 were measured as functions of temperature. The Sommerfeld constant ? was calculated from ?n and dBc2dT|Tc using the Ginzburg-Landau-Abrikosov-Gor'kov theory. The Debye temperature ?D was calculated from measurements of Young's modulus. The above parameters allowed calculations to be made of N(EF), the density of electronic states at the Fermi level, and ?, the electron-phonon coupling constant. It was found that ? more accurately reflected the Tc behavior than did N(EF) and that both electronic and phonon contributions had to be considered in the determination of ?.

Chapter 18 - Correlation of the Same Fields Imaged in the TEM, Confocal, LM, and MicroCT by Image Registration: From Specimen Preparation to Displaying a Final Composite Image  

Science Journals Connector (OSTI)

Abstract Correlated imaging is the process of imaging a specimen with two complementary modalities and then registering and overlaying the fields obtained in each modality to create a composite view. One of the images is made somewhat transparent, allowing detail in the underlying image to be visible and assisting in the registration of the two images. As an example, an image localizing a specific tissue component by fluorescence may be overlaid atop a TEM image of the same field. The resulting composite image would demonstrate specific ultrastructural features in the high-resolution TEM field, which are colorized in the overlay. Other examples include composites from MicroCT or soft X-ray images overlaid atop light microscopy or TEM images. Automated image registration may be facilitated by a variety of sophisticated computer programs utilized by high-throughput laboratories. This chapter is meant for the more occasional user wishing to align images manually. ImageJ is a public domain, image processing program developed at the National Institutes of Health and is available to anyone as a free download. ImageJ performs marvelously well for the purpose of image registration; therefore, step-by-step instructions are included here. Specimen handling, including fixation and choice of embedding media, is not straightforward for correlative imaging. A step-by-step description of the protocols which work in our laboratory is included for simultaneous localization in LM, EM and micro-CT, as well as maintaining GFP emission in tissue embedded for TEM.

Advanced NTR options. [Ta  

SciTech Connect (OSTI)

Advanced NTR concepts which offer performance improvements over the ROVER/NERVA designs have been investigated. In addition, the deliverable performance of low pressure operation and materials issues have been investigated. Based on current experience, a maximum exit gas temperature of 3200 K is likely achievable with a ZrC based PBR design. At 3200 K a low pressure NTR would have marginal performance advantage (Isp) over a high pressure system. If tantalum or other high melting point carbides are used then an exit gas temperature of 3500 K may be feasible. At 3500 K low pressure operation offers more significant performance improvements which could outweigh associated size and mass penalties.

Characterization of passive oxide film on a Ti-5%Ta-1.8%Nb alloy on exposure to severe oxidizing conditions  

SciTech Connect (OSTI)

This paper presents the results of a study on the characteristics of the passive oxide film that forms on the surface of an {alpha} + {beta} Ti-5%Ta-1.8%Nb alloy, which possesses good corrosion resistance in severe oxidizing environment of boiling 11.5 M nitric acid. Through systematic structure-property studies, the microstructure with low corrosion rate (< 1 mpy) in liquid, vapor and condensate phases of nitric acid was identified. The characteristics of the passive film, which imparts corrosion resistance to the alloy, are influenced by its microstructure, temperature and concentration of the acid. The microstructure, thickness and composition of the oxide film were characterized using different techniques. TiO{sub 2}, Nb{sub 2}O{sub 5} and Ta{sub 2}O{sub 5} formed on exposure to vapor and condensate phases, while TiO{sub 2} was observed on exposure to the liquid phase. Detailed microstructural studies showed that the passive film consists of nano-crystalline phases of titanium and tantalum oxides, predominantly anatase in an amorphous matrix. Based on these studies, the mechanism of corrosion of the alloy is derived. - Research Highlights: {yields}Liquid phase corrosion results in a thicker and protective oxide film. {yields}Oxide film is a mixture of amorphous and nano-crystalline anatase. {yields}Higher amounts of Nb{sub 2}O{sub 5} and Ta{sub 2}O{sub 5} form on vapor and condensate phase corrosion. {yields}High corrosion rate in condensate phase is due to selective dissolution of Ti in {alpha} phase.

Study of spontaneous and induced absorption in amorphous Ta{sub 2}O{sub 5} and SiO{sub 2} dielectric thin films  

SciTech Connect (OSTI)

Tantalum pentoxide (Ta{sub 2}O{sub 5}) and silicon dioxide (SiO{sub 2}) are common high-index and low-index materials used in dielectric optical coatings for high average-power lasers since high-density sputtered oxide films with absorption losses at near- and mid-infrared wavelengths of less than 1 ppm can be obtained. These oxides have been chosen to investigate the spontaneous and optically induced absorption at {lambda}{sub 0} = 1064 nm that occurs due to simultaneous illumination at shorter wavelengths. The effect is measured using the photothermal common-path interferometric technique. This technique is capable of detecting sub-ppm levels of optical absorption and tracking its changes at a given wavelength when a second laser beam is also incident on a thin film oxide sample. In this work, dual beam experiments are employed to assess changes in the optical absorption at {lambda}{sub 0} = 1064 nm in ion beam sputtered Ta{sub 2}O{sub 5} and SiO{sub 2} thin films deposited on fused silica substrates, with stimulating illumination {lambda}{sub 1} ranging from {lambda}{sub 1} = 266 nm to {lambda}{sub 1} = 780 nm. The power and wavelength of the stimulating radiation were found to affect the optical absorption at {lambda}{sub 0} = 1064 nm. Furthermore, the relaxation dynamics of the induced infrared absorption was found to be wavelength dependent and is thought to be associated with various electron traps existing in the forbidden gap that depend essentially on the film's preparation conditions. The significantly greater effect observed in Ta{sub 2}O{sub 5} at {lambda}{sub 1} = 266 nm is attributed to band-to-band transitions.

The effects of shockwave profile shape and shock obliquity on spallation in Cu and Ta: kinetic and stress-state effects on damage evolution(u)  

SciTech Connect (OSTI)

Widespread research over the past five decades has provided a wealth of experimental data and insight concerning shock hardening and the spallation response of materials subjected to square-topped shock-wave loading profiles. Less quantitative data have been gathered on the effect of direct, in-contact, high explosive (HE)-driven Taylor wave (or triangular-wave) loading profile shock loading on the shock hardening, damage evolution, or spallation response of materials. Explosive loading induces an impulse dubbed a 'Taylor Wave'. This is a significantly different loading history than that achieved by a square-topped impulse in terms of both the pulse duration at a fixed peak pressure, and a different unloading strain rate from the peak Hugoniot state achieved. The goal of this research is to quantify the influence of shockwave obliquity on the spallation response of copper and tantalum by subjecting plates of each material to HE-driven sweeping detonation-wave loading and quantify both the wave propagation and the post-mortem damage evolution. This talk will summarize our current understanding of damage evolution during sweeping detonation-wave spallation loading in Cu and Ta and show comparisons to modeling simulations. The spallation responses of Cu and Ta are both shown to be critically dependent on the shockwave profile and the stress-state of the shock. Based on variations in the specifics of the shock drive (pulse shape, peak stress, shock obliquity) and sample geometry in Cu and Ta, 'spall strength' varies by over a factor of two and the details of the mechanisms of the damage evolution is seen to vary. Simplistic models of spallation, such as P{sub min} based on 1-D square-top shock data lack the physics to capture the influence of kinetics on damage evolution such as that operative during sweeping detonation loading. Such considerations are important for the development of predictive models of damage evolution and spallation in metals and alloys.

Electronic Instability in a Zero-Gap Semiconductor: The Charge-Density Wave in (TaSe4)2I  

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

We report a comprehensive study of the paradigmatic quasi-1D compound (TaSe4)2I performed by means of angle-resolved photoemission spectroscopy (ARPES) and first-principles electronic structure calculations. We find it to be a zero-gap semiconductor in the nondistorted structure, with non-negligible interchain coupling. Theory and experiment support a Peierls-like scenario for the charge-density wave formation below TCDW=263??K, where the incommensurability is a direct consequence of the finite interchain coupling. The formation of small polarons, strongly suggested by the ARPES data, explains the puzzling semiconductor-to-semiconductor transition observed in transport at TCDW.

Electrical conduction mechanism in La{sub 3}Ta{sub 0.5}Ga{sub 5.3}Al{sub 0.2}O{sub 14} single crystals  

SciTech Connect (OSTI)

The electrical conduction mechanism in La{sub 3}Ta{sub 0.5}Ga{sub 5.3}Al{sub 0.2}O{sub 14} (LTGA) single crystals was studied by nonstoichiometric defect formation during crystal growth. Since stoichiometric LTGA is not congruent, the single crystal grown from the stoichiometric melt was Ta-poor and Al-rich, where Al atoms were substituted not only in Ga sites but also in Ta sites. The population of the substitutional Al in Ta sites increased with increasing oxygen partial pressure during growth (growth-pO{sub 2}) in the range from 0.01 to 1?atm. Below 600?C, substitutional Al atoms in Ta sites were ionized to yield holes, and thus the electrical conductivity of the LTGA crystal depended on temperature and the growth-pO{sub 2}. The dependence of the electrical conductivity on the growth-pO{sub 2} decreased as temperature increased. The temperature rise increases ionic conductivity, for which the dominant carriers are oxygen defects formed by the anion Frenkel reaction.

Feasibility study of a 6V-92TA homogeneous auto-ignited two-stroke (HAT) compressed-natural-gas-engine. Topical report, August 1989-May 1990  

SciTech Connect (OSTI)

The objective of the project was to modify a two-stroke 6V-92TA diesel engine to operate on natural gas using a simple system with gas addition to the compressor inlet and a spark plug for cold start and non-autoignition engine operation. The engine was to be operated at most speed-load conditions by autoignition of the premixed gas-air mixture. This concept is referred to as the Homogeneous Auto-Ignited Two-Stroke (HAT). Autoignition of carbureted natural gas was achieved at various loads and speeds in a 6V-92TA engine modified for operating on natural gas with the HAT concept. However, HAT engine operation up to 277 hp at 2100 rpm (diesel coach rating) was not achieved because early ignition in some cylinders caused knock and excessive heat transfer. Instead, the engine was operated up to 226 hp (767 N.m) at 2100 rpm, 181 hp (780 N.m) at 1650 rpm, 130 hp (773 N.m) at 1200 rpm, and 34 hp (368 N.m) at 650 rpm. Maximum brake thermal efficiency measured was 33.4% at 2100 rpm/219 hp. The corrected efficiency (to compensate for the unburned natural gas lost during the scavenging process) was higher than this. Steady-state emissions show very low NOx, total unburned HC lower than expected and reasonable CO levels. The lean air-fuel mixture and unburned exhaust gases in the cylinder resulted in very low NOx emissions.

In situ X-ray diffraction strain-controlled study of TiNbZr and TiNbTa shape memory alloys: crystal lattice and transformation features  

SciTech Connect (OSTI)

Phase and structure transformations in biomedical Ti21.8Nb6.0Zr (TNZ) and Ti19.7Nb5.8Ta (TNT) shape memory alloys (at.%) under and without load in the ? 150 to 100 S temperature range are studied in situ using an original tensile module for a low-temperature chamber of an X-ray diffractometer. Alpha?- and beta-phase lattice parameters, the crystallographic resource of recovery strain, phase and structure transformation sequences, and microstress appearance and disappearance are examined, compared and discussed. For both alloys, the crystallographic resource of recovery strain decreases with temperature increase to become 4.5% for TNZ and 2.5% for TNT alloy (at RT). Loading at low temperatures leads to additional ??-phase formation and reorientation. Heating under load, as compared to strain-free heating, affects the reverse transformation sequence of both alloys in different ways. For TNZ alloy, strain-free heating results in simultaneous ??? and ???? transformations, whereas during heating under stress, they are sequential: ? + ???? precedes ????. For TNT alloy, strain-free heating results in reverse ???? transformation, whereas during heating under stress, ???? transformation is preceded by ??-phase reorientation. - Highlights: Comparative in situ XRD analysis of TiNbZr(Ta) shape memory alloys is realized. Lattice parameters of ?- and ??-phases are calculated in the ? 150 to + 100 C range. The higher the temperature, the lower the ???? transformation strain. Loading at low temperatures results in ??-phase formation and reorientation. Transformation sequences upon heating with and without loading are different.

SciTech Connect (OSTI)

This effort addressed an evaluation of human machine interfaces (HMIs) in Room TA-50-1-60/60A of the Radioactive Liquid Waste Treatment Facility (RLWTF). The evaluation was performed in accordance with guidance outlined in DOE-STD-3009, DOE Standard Preparation Guide for U.S. Department of Energy Nonreactor Nuclear Facility Documented Safety Analyses, 2006 [DOE 2006]. Specifically, Chapter 13 of DOE 2006 highlights the 10 CFR 830, Nuclear Safety Management, 2012, [CFR 2012] and DOE G 421.1-2 [DOE 2001a] requirements as they relate to the human factors process and, in this case, the safety of the RLWTF. The RLWTF is a Hazard Category 3 facility and, consequently, does not have safety-class (SSCs). However, safety-significant SSCs are identified. The transuranic (TRU) wastewater tanks and associated piping are the only safety-significant SSCs in Rooms TA-50-1-60/60A [LANL 2010]. Hence, the human factors evaluation described herein is only applicable to this particular assemblage of tanks and piping.

Experimental and theoretical studies on the C15 intermetallic compounds MV{sub 2} (M = Zr, Hf and Ta): Elasticity and phase stability  

SciTech Connect (OSTI)

The phase stability of C15 HfV{sub 2} was studied by specific heat measurements. The elastic constants of C15 HfV{sub 2} were measured by the resonant ultrasound spectroscopy. Total energy and electronic structure of C15 intermetallic compounds MV{sub 2} (M = Zr, Hf and Ta) were calculated using the linear muffin tin orbital (LMTO) method. The band structures at X-point near the Fermi level were used to understand the anomalous shear moduli of the C15 HfV{sub 2} and ZrV{sub 2}. It was found that the double degeneracy with a linear dispersion relation of electronic levels at the x-point near the Fermi surface is mainly responsible for the C15 anomalous elasticity at high temperatures. The densities of states at Fermi level and the geometry of the Fermi surface were used to explain the low temperature phase instability of C15 HfV{sub 2} and ZrV{sub 2} and the stability of C15 TaV{sub 2}. The relationship between the anomalous elasticity and structural instability of C15 HfV{sub 2} and ZrV{sub 2} were also studied.

STRUCTURE AND HIGH-FIELD PERFORMANCE OF JELLY ROLL PROCESSED Nb{sub 3}Sn WIRES USING Sn-Ta AND Sn-Ti BASED ALLOY SHEET  

SciTech Connect (OSTI)

Sn-Ta based alloy buttons of different compositions were prepared by the melt diffusion process among constituent metal powders, and then pressed into plates. Meanwhile Sn-Ti based alloy plates were sliced from the melt and cast ingot. Resulting Sn-based alloy plates were rolled into thin sheets. The Sn-based alloy sheet was laminated with a Nb sheet, and wound into a Jelly Roll (JR) composite. The composite was encased in a sheath, and fabricated into a thin wire followed by the heat treatment. The application of hydrostatic extrusion is useful at the initial stage of the fabrication. The JR wires using Sn-Ta and Sn-Ti based alloy sheets show a non-Cu J{sub c} of {approx}250 A/mm{sup 2} and {approx}150 A/mm{sup 2} at 20 T and 22 T, respectively, at 4.2 K. It has been found that the Nb impregnates into the Sn-based alloy layers during the reaction, and Nb{sub 3}Sn layers are synthesized by the mutual diffusion between the Nb sheet and the Sn-based alloy sheet without formation of voids. Sn-Ti based alloy sheets are attractive due to their easiness of mass production. Structure and high-field performance of JR processed Nb{sub 3}Sn wires prepared from Sn-based alloy sheets with different compositions are compared in this article.

Emissions and engine performance from blends of soya and canola methyl esters with ARB {number_sign}2 diesel in a DCC 6V92TA MUI engine  

SciTech Connect (OSTI)

A Detroit Diesel 6V92TA MUI engine was operated on several blends of EPA No. 2 diesel, California ARB No. 2 diesel, soya methyl ester (SME) and canola methyl ester (CME). Various fuels and fuel blend characteristics were determined and engine emissions from these fuels and blends were compared. Increasing percentages of SME and CME blended with either ARB or EPA diesels led to increased emissions of NO{sub x}, CO{sub 2} and soluble particulate matter. Also noted were reductions in total hydrocarbons, CO and insoluble particulate matter. Chassis dynamometer tests conducted on a 20/80 SME/ARB blend showed similar emissions trends. The data suggest that certain methyl ester/No. 2 diesel blends in conjunction with delays in engine timing and technologies that reduce the soluble fraction of particulate emissions merit further exploration as emissions reducing fuel options for North American mass transits (except in California, which mandates ARB diesel).

Optical breakdown threshold in nanosecond high repetition second harmonic generation by periodically poled Mg-doped LiTaO{sub 3} crystal  

SciTech Connect (OSTI)

Our study shows that a local temperature increase of ?1 K in the crystal lattice caused by second harmonic generation (SHG) and two-photon absorption of 532 nm radiation at the rear of periodically poled stoichiometric LiTaO{sub 3} crystal by changing spontaneous polarization induces a pyroelectric field ?10 kV/cm, accelerating free electrons to an energy of ?10 eV, followed by optical breakdown and crystal damage. Theoretical analysis leads to an explicit expression for the threshold laser fluence of optical breakdown giving ?1.2 J/cm{sup 2} for 1064 nm input radiation in 6.8 kHz pulsed SHG operation, agreeing well with the experimentally found value ?1.32 J/cm{sup 2}.

Neutron capture cross sections of /sup 178/,/sup 179/,/sup 180/Hf and the origin of nature's rarest stable isotope /sup 180/Ta  

SciTech Connect (OSTI)

The neutron capture cross sections of /sup 178/,/sup 179/,/sup 180/Hf were measured in the energy range 2.6 keV to 2 MeV. The average capture cross sections were derived and fitted in terms of strength functions. Resonance parameters for the observed resonances below 10 keV were determined by shape analysis. Maxwellian-averaged capture cross sections were computed for thermal energies with kT between 5 and 100 keV. The cross sections for kT = 30 keV were used to determine the population probability of the 8- isomeric level in /sup 180/Hf by neutron capture as (1.24 +- 0.06)% and the r-process abundance of /sup 180/Hf as 0.0290 (Si = 10/sup 6/). These quantities served to analyze s- and r-process nucleosynthesis of /sup 180/Ta, nature's rarest stable isotope.

Magnetization dynamics and interface studies in ion-beam sputtered Si/CoFeB(8)/MgO(4)/CoFeB(8)/Ta(5) structures  

SciTech Connect (OSTI)

The interface roughness, Boron distribution in bulk CoFeB and at interface, Gilbert damping constant (?), and inhomogeneous broadening in ion-beam sputtered Si/CoFeB(8)/MgO(4)/CoFeB(8)/Ta(5) structures are found to be sensitive to the MgO growth process. The ion-assist and reactive growth processes that result in sharper interfaces of width ?0.5?nm lead to smaller ? of 0.0050??0.0003 and 0.0060??0.0002 and inhomogeneous broadening ?H{sub 0} of 3??0.3 and 1??0.3?Oe, respectively. On the other hand, the post-oxidation method results in rough interface and higher retention of Boron in CoFeB leading to higher values for ? and ?H{sub 0} as 0.0080??0.0006 and 5??0.3?Oe, respectively.

Effect of pre-treatment of the substrate surface by energetic C+ ion bombardment on structure and nano-tribological characteristics of ultra-thin tetrahedral amorphous carbon (ta-C) protective coatings  

Science Journals Connector (OSTI)

Depositing an ultra-thin tetrahedral amorphous carbon (ta-C) protective coating on the surface of the recording heads in magnetic tape drives can improve the tribological problems at the head/tape interface. In this work the effect of pre-treatment of the surface of AlTiC substrate (main bearing surface of head in contact with tape) by C+ ions of moderate energy (smaller than 400?eV) on the structural and tribo-mechanical behaviours of the coated surfaces is studied. Sample preparation consisted of two separate stages of surface pre-treatment and deposition of the protective film, and was done by means of filtered cathodic vacuum arc. Structure of the ta-C film and its interface with the substrate were studied by transmission electron microscopy and time-of-flight secondary ion mass spectrometry depth profiling. The results revealed the formation of a broader, dense atomically mixed layer at the ta-C filmsubstrate interface of the pre-treated samples comparing with that of the samples without pre-treatment. Chemical characterization of thin diamond-like carbon coatings was conducted by means of x-ray photoelectron spectroscopy and the surface pre-treatment was found to have a remarkable effect on increasing the sp3 hybridization fraction in the ta-C overcoat. Nano-tribological properties of the treated surfaces were examined using ball-on-flat wear test at very low load (20?mN). There was a good correlation between the surface and structure characteristics of the film, and the tribological results and the pre-treated surfaces presented a very low coefficient of friction and higher wear life. The experimental results demonstrate the effectiveness of bombardment of the surface with C+ ions of moderate ion energy to improve the structural and tribo-mechanical properties of the protective ta-C films on the magnetic head substrate material.

Two ternary compounds, KTaB{sub 2}O{sub 6} and K{sub 3}Ta{sub 3}B{sub 2}O{sub 12} were confirmed in the system K{sub 2}O-Ta{sub 2}O{sub 5}-B{sub 2}O{sub 3}. Crystal structure of compound KTaB{sub 2}O{sub 6} has been refined from X-ray powder diffraction data using the Rietveld method. The compound crystallizes in the orthorhombic, space group Pmn2{sub 1} (No. 31), with lattice parameters a = 7.3253(4) A, b = 3.8402(2) A, c = 9.3040(5) A, z = 2 and D{sub calc} = 4.283 g/cm{sup 3}. The powder second harmonic generation (SHG) coefficients of KTaB{sub 2}O{sub 6} and K{sub 3}Ta{sub 3}B{sub 2}O{sub 12} were five times and two times as large as that of KH{sub 2}PO{sub 4} (KDP), respectively.

First-time remote sensing of NO2 vertical distributions in an urban street canyon using Topographic Target Light scattering Differential Optical Absorption Spectroscopy (ToTaL-DOAS)  

Science Journals Connector (OSTI)

Topographic Target Light scattering Differential Optical Absorption Spectroscopy (ToTaL-DOAS) measurements were performed in a street canyon in Gwangju, Korea (3510?51.43?N, 12652?53.74?E) during a period of 10 days in October 2010. NO2 slant volume mixing ratios (VMRs) at the lowest elevation angle (EL) of 1, as obtained from ToTaL-DOAS measurements, were validated via comparisons with collocated in situ ground data, showing good agreement within a scatter range of 20% during the entire measurement period, and within a scatter range of 15% when cloudy days were excluded. For the first time, based on inversion calculations using ToTaL-DOAS data, we retrieved NO2 vertical distributions that consist of five layers (from 6 to 118m) for three measurement days. We obtained generally decreasing NO2 \\{VMRs\\} with altitude, whereas increased NO2 \\{VMRs\\} at two elevated layers (619m and 1933m) were observed on 26 and 27 October. We obtained a coefficient of determination (R2) of 0.87 (0.61) between slant \\{VMRs\\} at 1 EL (retrieved NO2 \\{VMRs\\} in the layer from 6m to 19m) and in situ data, with the scatter of the correlation being within the 15% (10%) range. The relation between retrieved NO2 \\{VMRs\\} at 619m and slant \\{VMRs\\} at 1 EL yielded an R2 value of 0.97, with the scatter of the correlation being within the 5% range. The results demonstrate that the ToTaL-DOAS technique is a useful tool in identifying the temporal and vertical characteristics of NO2 \\{VMRs\\} in an urban street canyon with a complex geometry.

First-principles calculations of the electronic structure and optical properties of K{sub 1-x}Na{sub x}TaO{sub 3} (x=0, 0.25, 0.5, 0.75, 1)  

SciTech Connect (OSTI)

The first-principles calculations are performed to investigate the cubic phase composite K{sub 1-x}Na{sub x}TaO{sub 3}(x=0, 0.25, 0.5, 0.75, 1), by using density functional theory (DFT) with the full potential linearized augmented plane wave (FP-LAPW) method. The energy band structures, density of states (DOS), electron density and optical properties are obtained. The results show that Na ion plays an important role in K{sub 1-x}Na{sub x}TaO{sub 3}. With the content of Na ion increasing, the changes of lattice parameters, energy gaps, bond lengths and optical properties of K{sub 1-x}Na{sub x}TaO{sub 3} are regular. Moreover, the dependence of ferroelectric photocatalysis on both optical properties and internal electronic structure are analyzed in detail. It is proposed that the doped materials are promising photocatalytic materials. - Graphical abstract: The density of states (DOS) of K{sub 1-x}Na{sub x}TaO{sub 3} (x=0.5).

Chemical surety material decontamination and decommissioning of Los Alamos National Laboratory Chemical Surety Material Laboratory area TA-3, building SM-29, room 4009  

SciTech Connect (OSTI)

From 1982 through 1987, Los Alamos National Laboratory (LANL) performed surety laboratory operations for the U.S. Army Medical Research and Development Command (MRDC). Room 4009 in building SM-29, TA-3, was used as the laboratory for work with the following chemical surety material (CSM) agents: sarin (GB), soman (GD), lewisite (L), and distilled mustard (HD) radio-labelled with H{sup 3} or C{sup 14}. The work was confined to three CSM-certified fume hoods, located in room 4009 (see diagram in Appendix C). The laboratory ceased all active operations during the late 1986 and early 1987 period. From 1987 until 1993 the laboratory was secured and the ventilation system continued to operate. During late 1992, the decision was made to utilize this laboratory space for other operations, thus a decision was made to dismantle and reconfigure this room. LANL sub-contracted Battelle Memorial Institute (BMI) to draw upon the CSM experience of the technical staff from the Hazardous Materials Research Facility (HMRF) to assist in developing a decontamination and decommissioning plan. BMI was subcontracted to devise a CSM safety training course, and a sampling and air monitoring plan for CSM material to ensure personnel safety during all disassembly operations. LANL subcontracted Johnson Controls personnel to perform all disassembly operations. Beginning in early 1993 BMI personnel from the HMRF visited the laboratory to develop both the safety plan and the sample and air monitoring plan. Execution of that plan began in September 1993 and was completed in January 1994.

Influence of the B-site ordering on the magnetic properties of the new La{sub 3}Co{sub 2}MO{sub 9} double perovskites with M = Nb or Ta  

SciTech Connect (OSTI)

Double perovskites La{sub 3}Co{sub 2}NbO{sub 9} and La{sub 3}Co{sub 2}TaO{sub 9} have been prepared by both solid state and sol-gel synthesis. The crystal structures have been studied from X-ray and neutron powder diffraction data. Rietveld refinements show that the crystal structure is monoclinic (P2{sub 1}/n), with different degrees of ordering of B' and B'' cations, with octahedra tilted according to the Glazer notation a{sup -}b{sup -}c{sup +}. Occupancy refinements show that the solid state materials are more B-site ordered than the sol-gel ones. Magnetization measurements show that these perovskites show two magnetic contributions, one with spontaneous magnetization and other with linear behaviour with the magnetic field associated to antiferromagnetic correlations. In the samples synthesized by solid state the spontaneous magnetization is more important than those synthesized by the sol-gel and present T{sub C} of 62 K for Nb and 72 K for Ta. On the other hand, materials prepared by sol-gel have T{sub C} 20 K for Nb and 40 K for Ta, respectively and major presence of the antiferromagnetic contribution. The competition between these magnetic behaviours is interpreted, by a microscopic point of view, as to be due to the different degrees of Co{sup 2+} ions disorder on the B site of the double perovskite structure. This disorder affects the ratio between the antiferromagnetic Co{sup 2+}-O-Co{sup 2+} and the ferromagnetic Co{sup 2+}-O-M{sup 5+}-O-Co{sup 2+} couplings proposed for the system.

Effects of additive C{sub 4}F{sub 8} during inductively coupled BCl{sub 3}/C{sub 4}F{sub 8}/Ar plasma etching of TaN and HfO{sub 2} for gate stack patterning  

SciTech Connect (OSTI)

In this work, the authors investigated the etching characteristics of TaN and HfO{sub 2} layers for gate stack patterning in BCl{sub 3}/Ar and BCl{sub 3}/C{sub 4}F{sub 8}/Ar inductively coupled plasmas and the effects of C{sub 4}F{sub 8} addition on the etch selectivity of the TaN to the HfO{sub 2} layer. Addition of C{sub 4}F{sub 8} gas to the BCl{sub 3}/Ar chemistry improved the TaN/HfO{sub 2} etch selectivity because adding the C{sub 4}F{sub 8} gas enhances the formation of the CF{sub x}Cl{sub y} passivation layer on HfO{sub 2} surface and decreased the HfO{sub 2} etch rate more rapidly than the TaN etch rate in a disproportionate way. Reduction in the etch time for HfO{sub 2} layer also increases the TaN/HfO{sub 2} etch selectivity because the etch time gets closer to the initiation time for HfO{sub 2} etching.

Science Journals Connector (OSTI)

Temperature-stable low-loss Ca 5 ? x A x B 2 Ti O 12 ( A = Mg Zn Ni and Co; B = Nb and Ta)dielectrics suitable for microwave telecommunication applications were prepared by the conventional solid-state ceramic route. Investigations were made on the structure and microstructure of the ceramics employing x-ray and scanning electron microscopic techniques. The dielectric properties were measured in the 3.5 7 GHz frequency range. The time domain simulation of electromagnetic wave interaction with dielectric materials using three-dimensional transmission line matrix modeling methods is presented. Excellent agreement between experimental and simulated values of microwavedielectric properties was observed. The materials are potential candidates for applications in filters oscillators and high efficiency low-loss dielectric antennas working especially at millimeter wave region.

Excess lithium salt functions more than compensating for lithium loss when synthesizing Li6.5La3Ta0.5Zr1.5O12 in alumina crucible  

Science Journals Connector (OSTI)

Abstract Garnet type electrolyte Li6.5La3Ta0.5Zr1.5O12 (LLZTO) was prepared by conventional solid-state reaction in alumina crucibles and excess lithium salt (from 0% to 50mol%) was added into the starting materials to investigate the effects of excess lithium salt on the property of LLZTO. SEM, XRD and AC impedance were used to determine the microstructure, phase formation and Li-ion conductivity. Cubic garnet with a minor second phase LiAlO2 in the grain boundary was obtained for the pellets with excess lithium salt. As the amount of excess lithium salt increased, more Al element diffused from alumina crucibles to LLZTO pellets and reacted with excess lithium salt to form liquid Li2OAl2O3 phase in the grain boundary, which accelerated the pellets' densification and reduced lithium loss at a high temperature. Ionic conductivity of LLZTO pellets increased with the amount of excess lithium salt added and leveled off at ?4נ10?4Scm?1 when lithium salt exceeded 30mol%. The performance of Li-air batteries with hybrid electrolytes, using homemade LLZTO thin pellets as solid electrolytes, was investigated. The LLZTO thin pellet with more excess lithium salt in starting material had a higher density and resulted in better cell performance.

Cold Vacuum Dryer (CVD) Facility Fire Protection System Design Description (SYS 24)  

SciTech Connect (OSTI)

This system design description (SDD) addresses the Cold Vacuum Drying (CVD) Facility fire protection system (FPS). The primary features of the FPS for the CVD are a fire alarm and detection system, automatic sprinklers, and fire hydrants. The FPS also includes fire extinguishers located throughout the facility and fire hydrants to assist in manual firefighting efforts. In addition, a fire barrier separates the operations support (administrative) area from the process bays and process bay support areas. Administrative controls to limit combustible materials have been established and are a part of the overall fire protection program. The FPS is augmented by assistance from the Hanford Fire Department (HED) and by interface systems including service water, electrical power, drains, instrumentation and controls. This SDD, when used in conjunction with the other elements of the definitive design package, provides a complete picture of the FPS for the CVD Facility.

TEM Examination of Advanced Alloys Irradiated in ATR  

SciTech Connect (OSTI)

Successful development of materials is critical to the deployment of advanced nuclear power systems. Irradiation studies of candidate materials play a vital role for better understanding materials performance under various irradiation environments of advanced system designs. In many cases, new classes of materials have to be investigated to meet the requirements of these advanced systems. For applications in the temperature range of 500 800C which is relevant to the fast neutron spectrum burner reactors for the Global Nuclear Energy Partnership (GNEP) program, oxide dispersion strengthened (ODS) and ferritic martensitic steels (e.g., MA957 and others) are candidates for advanced cladding materials. In the low temperature regions of the core (<600C), alloy 800H, HCM12A (also called T 122) and HT 9 have been considered.

By increasing Li ions in KNLNTS, the grains grow up and the crystal structure changes from orthorhombic to tetragonal. When 0.03 ? x ? 0.05, the ceramics structure lays in PPT region. Polarization versus electric field (P-E) hysteresis loops at room temperature show good ferroelectric properties and the remnant polarization decreases by increasing Li content while coercive electric keeps almost unchanged. In PPT region, taking x = 0.04 as an example, the sample shows excellent dielectric properties: the dielectric constant is 1159 and loss tangent is 0.04, while the piezoelectric constant d{sub 33} is 245 pC/N and kp is 0.44 at room temperature, it is promising for (K{sub 0.5}Na{sub 0.5}){sub 1-x}Li{sub x}Nb{sub 0.84}Ta{sub 0.1}Sb{sub 0.06}O{sub 3} with 4 at. % Li to substitute PZT.

Addressing concerns related to geologic hazards at the site of the proposed Transuranic Waste Facility , TA-63, Los Alamos National Laboratory: focus on the current Los Alamos Seismic Network earthquake catalog, proximity of identified seismic events to the proposed facility , and evaluation of prev  

SciTech Connect (OSTI)

This technical paper presents the most recent and updated catalog of earthquakes measured by the Los Alamos Seismic Network at and around Los Alamos National Laboratory (LANL), with specific focus on the site of the proposed transuranic waste facility (TWF) at Technical Area 63 (TA-63). Any questions about the data presented herein, or about the Los Alamos Seismic Network, should be directed to the authors of this technical paper. LANL and the Los Alamos townsite sit atop the Pajarito Plateau, which is bounded on its western edge by the Pajarito fault system, a 35-mile-long system locally comprised of the down-to-the-east Pajarito fault (the master fault) and subsidiary down-to-the-west Rendija Canyon, Guaje Mountain, and Sawyer Canyon faults (Figure 1). This fault system forms the local active western margin of the Rio Grande rift near Los Alamos, and is potentially seismogenic (e.g., Gardner et al., 2001; Reneau et al., 2002; Lewis et al., 2009). The proposed TWF area at TA-63 is situated on an unnamed mesa in the north-central part of LANL between Twomile Canyon to the south, Ten Site Canyon to the north, and the headwaters of Canada del Buey to the east (Figure 2). The local bedrock is the Quaternary Bandelier Tuff, formed in two eruptive pulses from nearby Valles caldera, the eastern edge of which is located approximately 6.5 miles west-northwest of the technical area. The older member (Otowi Member) of the Bandelier Tuff has been dated at 1.61 Ma (Izett and Obradovich 1994). The younger member (Tshirege Member) of the Bandelier Tuff has been dated at 1.256 Ma (age from Phillips et al. 2007) and is widely exposed as the mesa-forming unit around Los Alamos. Several discrete cooling units comprise the Tshirege Member. Commonly accepted stratigraphic nomenclature for the Tshirege Member is described in detail by Broxton and Reneau (1995), Gardner et al. (2001), and Lewis et al. (2009). The Tshirege Member cooling unit exposed at the surface at TA-63 is Qbt3. Understanding the subtle differences between Tshirege Member cooling units and the nature of the contacts between cooling units is critical to identifying the presence or absence of faults associated with the Pajarito fault system on the Pajarito Plateau. The Los Alamos Seismic Network (LASN) continuously monitors local earthquake activity in the Los Alamos area in support of LANL's Seismic Hazards program. Seismic monitoring of LANL facilities is a requirement of DOE Order 420.1B (Facility Safety). LASN currently consists of nine permanent seismic instrument field stations that telemeter real-time sensitive ground motion data to a central recording facility. Four of these stations are located on LANL property, with three of those within 2.5 miles of TA-63. The other five stations are in remote locations in the Jemez Mountains, Valles Caldera, St Peters Dome, and the Caja del Rio plateau across the Rio Grande from the Los Alamos area. Local earthquakes are defined as those with locations within roughly 100 miles of Los Alamos. Plate 1 shows the current LASN station locations and all local earthquakes recorded from 1973 through 2011. During this time period, LASN has detected and recorded over 850 local earthquakes in north-central New Mexico. Over 650 of these were located within about 50 miles of Los Alamos, and roughly 60 were within 10 miles. The apparent higher density of earthquakes close to Los Alamos, relative to the rest of north-central New Mexico, is due largely to the fact that LASN is a sensitive local seismic network, recording many very small nearby events (magnitude less than 1.0) that are undetectable at greater distances.

Decommissioning of the TA-42 plutonium contaminated incinerator facility  

SciTech Connect (OSTI)

During 1978, a plutonium (/sup 239/Pu) contaminated incinerator facility at the Los Alamos National Laboratory, Los Alamos, New Mexico, was decommissioned. The project involved dismantling the facility and burying the debris at an on-site radioactive solid waste disposal/storage area. Contaminated soil from the 5000 m/sup 2/ area was also buried. The facility was constructed in 1951 to incinerate /sup 239/Pu contaminated wastes. It was later used as a decontamination facility. The major features included a 185-m/sup 2/ floor area control building, incinerator, cyclone dust collector, spray cooler, venturi scrubber, air filter bank, ash separator, and two 140 000-liter ash storage tanks. Six-hundred cubic meters of debris and 1200 m/sup 3/ of soil contaminated with less than 10 nCi /sup 239/Pu per gram of soil were buried at the Laboratory disposal area. Five cubic meters of /sup 239/Pu contaminated ash residues containing more than 10 nCi /sup 239/Pu per gram of waste were packaged and stored to meet the Department of Energy's 20-year retrievable storage criteria. The operation consumed 80 work days and 5800 manhours at a cost of $150 000. This report presents the details concerning decommissioning procedures, the health physics, the waste management, the environmental surveillance results, and a cost breakdown for the operation.
