Аннотация: На основании анализа литературных данных установлено, что структура расплавленных индивидуальных хлоридов редкоземельных металлов представляет собой рыхлую ионную сетку с локальной октаэдрической конфигурацией каждого катиона. Перенос электричества в таких расплавах осуществляется как катионамиLn 3+, так и анионами Cl-. Основных механизмов электропереноса два: поступательное движение отдельных ионов и трансляционный перенос, при котором несколько ионов одновременно перепрыгивают в соседние положения равновесия

POTENTIAL
Аннотация: Cost remains a major barrier for commercial success of SOFC. SRI evaluated a cost competitive SOFC manufacturing process developed by Russian researchers who work in this field since the late 1950s. The process is based on thermal decomposition of organo-metallic compounds. Cost savings are possible because: (a) the deposition process is performed at atmospheric pressure, (b) all layers (electrolyte, interface layers, and anode) are deposited sequentially within the same reactor, and (c) the raw materials and equipment are inexpensive. Electrochemical test cells (sections of a single SOFC element) prepared at the IHTE have been analyzed and tested at SRI International. Each cell consists of LSM cathode, YSZ electrolyte, and platinum paste anode. Composition and microstructure were determined by SEM examination and x-ray diffraction. The electrolyte had a 0.92ZrO2+0.08Y2O3 composition with thickness 17-80 micrometers; it had cubic fluoride type structure similar to compact samples of the same material. Size of crystallites at the external layer of the electrolyte was 1-9 micrometers. In SRI's testing, a power density of ?0.45 W/cm2 was measured at 900°C. The power produced by elements under a constant load was stable for 1,500 hours of continuous operation, and the fuel elements survived multiple on/off cycles. Examination with a scanning electron microscope (SEM) before and after the tests of the elements' microstructures showed no significant transformation. SRI concluded that the core technology of the Russian SOFC generators is reliable, has high technical potential, and may offer strong competitive advantage for producing commercial products at a cost of under $500/kW.

Аннотация: The structure of gold deposits produced by electrolysis of molten eutectic NaCl-KCl-CsCl at 500-700°e in an inert atmosphere is studied. The initial process on the gold cathode is the epitaxial growth of a layer up to 3 µm thick with a smoothed surface and a considerably later growth of grain boundaries. Gradually, on the protruding parts of deposit, the growth of dendrites starts. The dendrites are the major form of gold deposits. Typical gold dendrites are two-dimensional 2D<112> and 2D<112>n<110> and three-dimensional 3D<100>. Upon supplying air into the atmosphere above the melt at high current densities at the initial period there appears a powder comprising particles of a rounded twisted shape. Probable mechanisms leading to the formation of the iroundedi powder are discussed.

A method for removing 2 impurities from the melt has been developed.??The results of corrosion tests performed on samples of nickel-based alloys in a setup with natural circulation with maximum melt temperature up to 700?C and redox potential of the system 1.25n1.33 V relative to a beryllium comparison electrode are presented. It is shown that deep removal of oxidizing impurities from the melt and maintaining a low redox potential give slow uniform corrosion (less than 5µm/yr) of Kh80MTYu and KhN80M-VI samples. After the tests were completed,none of the alloys studied exhibited any tendency toward intercrystallite absorption.

Аннотация: The electrical conductivity of lithium diphosphate Li4P2O7 has been measured and jump-like increasing of ionic conductivity at 913 K has been found. The crystal structure of Li4P2O7 has been refined using high temperature neutron diffraction at 300–1050 K. At 913 K low temperature triclinic form of Li4P2O7 transforms into high temperature monoclinic one, space group P21/n, a=8.8261(4) Å, b=5.2028(4) Å, c=13.3119(2) Å, β=104.372(6)°. The migration maps of Li+ cations based on experimental data implemented into program package TOPOS have been explored. It was found that lithium cations in both low- and high temperature forms of Li4P2O7 migrate in three dimensions. Cross sections of the migrations channels extend as the temperature rises, but at the phase transition point have a sharp growth showing a strong “crystal structure – ion conductivity” correlation.

Аннотация: DFT calculations with six LDA, GGA, and hybrid functionals have been performed using the CRYSTAL09 code to describe the crystal structure and vibrational spectra of Y2CaGe4O12 cyclotetragermanate, a new optical host. Two space groups P4/nbm and Cmme have been considered. The former corresponds to a mixed (0.5 Ca + 0.5 Y) distribution at the octahedral sites found from the results of Rietveld refinement of room temperature powder XRD pattern; the latter refers to the model of crystallographically nonequivalent calcium and yttrium atomic setting in distorted oxygen octahedrons. The most accurate geometry description has been obtained with the WC1LYP and PBE (n = 6) hybrid functionals, while the B3LYP calculation provides the best agreement between the recorded infrared and Raman spectra and their computed counterparts. Assignments of most of the observed bands to vibrational modes are given. The comparison between calculated and experimental frequencies shows a general good agreement for the spectra below 600 cm–1. The relationship between selected infrared bands and Raman lines, internal vibrations of the [Ge4O12] unit, and external modes is briefly discussed

Аннотация: This paper represents the experimental data on a quantitative composition of cathode UO2-ZrO2 deposits, which are formed through simultaneous electrolytic reduction of UO22+ ions to UO2 and the exchange between the UO2 and Zr4+ ions present in the molten (NaCl-KCl) equim.-UO2Cl2-ZrCl4 electrolyte. A scheme for the formation of UO2-ZrO2 deposits containing up to 98 mol. % of ZrO2 is provided. The fraction of zirconium dioxide decreased as the ZrCl4 concentration decreased and as current density and electrolysis times increased. The electrolyte temperature influence on the average composition of the UO2-ZrO2 deposit was found to be insignificant. The structure of the cathode deposit was analyzed. The established regularities are explained by the change in the reduction and exchange reaction rates at the cathode.

Аннотация: Room-temperature measurements of diffusion coefficients for deuterium in proton conductors La0.9Sr0.1ScO3 -δ and BaZr0.9Y0.1O3 -δ which contain dissolved H2O vapor have been performed. The concentration of oxygen structure vacancies in oxides after treatment in vapor was close to zero. A diffusion source of deuterium was created by ion implantation; measurement of the concentration–distance distribution of deuterium in samples was performed in situ during implantation. The NRA technique and 2H(d,p)3H reaction at an energy of the incident beam of 650 keV were used. For the initial and boundary conditions of the diffusion problem which were realized in the work, a solution of the inhomogeneous Fick equation was obtained. Using the technique developed, measurements of the diffusion coefficients for hydrogen in proton conductors were for the first time performed directly. For the BaZr0.9Y0.1O3 -δ oxide, the directly gained values of diffusion coefficients agree rather well with those obtained from the proton conductivity with the use of Nernst–Einstein equation

The crystal structure of each sample was characterised using X-ray diffraction. Doping the samples with Al reduced the synthesis time. The cubic modification of Li7La3Zr2O12 was obtained by treatment at 1150 °C for 1 h. The conductivity of the ceramic samples was studied by complex impedance spectroscopy at 25–230 °C. The composition with x = 0.15 had the highest total conductivity, 3.4·10−4 S cm−1, at 25 °C.

Аннотация: This study examines potential benefits of adopting ultrashort optical pulses in fuel cell technology. General principles for jumping migration of protons in resonant laser fields have been elaborated. We find that, depending upon the frequency of phonon assistance, the effective activation energy for migration can be strongly diminished when excitation pulses are used. The obtained results indicate that at room temperature the picosecond-laser-induced proton transfer in rutile type oxides is much faster than that for thermal activation. Our estimates are in good agreement with time-resolved measurements for rutile samples excited by infrared light. The fundamentals of this transfer process are briefly analyzed in the light of structure diffusion and vibrational mode models. The most important conclusion to emerge from our work is that the use of the optical stimulation shows considerable promise as a means for decreasing the operating temperature of solid oxide fuel cells based on proton hopping transport.

Аннотация: Li4Ti4.92(CrV)0.04O12/C composites were synthesized at 800 °C under a flow of argon/acetylene gas mixture taken in the 40:1volumetric ratio. X-ray diffraction (XRD), thermogravimetric analysis (TGA), magnetic susceptibility, Raman spectroscopy, and electron microscopy (TEM) were used to characterize the phase structure, composition, and morphology of the composites. Transmission electron microscopy and Raman spectroscopy confirmed that carbon exists on the surface of the spinel matrix. The composites proved to have a modified structure in comparison with the pristine spinel phase.

Аннотация: Empirical equations describing the electrical conductivities of fluorides and fluoride-oxide mixtures have been obtained. These equations are based on two suppositions: (a) electrical conductivity of ionic molten substances is connected with the electronic structure of the cations; (b) the electrical conductivity of ionic melts can be expressed in terms of molar volume. In molten mixtures, the form of the electrical conductivity isotherm depends on the interaction between the components

Аннотация: The influence of sodium (Na) additions with different chemical natures (sodium peroxide Na2O2 and sodium chloride NaCl on the mechanism and kinetics of aluminum Al corrosion was investigated. Auger electron spectroscopy, x-ray photoelectron spectroscopy, and x-ray structure spectroscopy were used to analyze the corrosion products. Na2O2 promoted formation of more compact, less defective films. At high temperature, the introduction of peroxide into the salt phase resulted in the emergence of different oxigen (O) ions and a film with higher O content NaCl additions destroyed the coating through formation of pits and local solutions of oxide layers. The greater the concentration of active ions was, the less the initial depassivation potential was. Increases in anodic polarization and concentrations of chloride ions (Cl-) diminished induction time. Films consisted only of alpha-LiAlO2, a crystal modification of lithium aluminate
