Аннотация: The present paper reports on the preparation of three- and bilayer graphene and boron doped graphene defect-free large films by electrochemical synthesis in molten alkali chlorides. It is shown that the morphology and composition of the resulting graphene and boron doped graphene films with total boron concentration up to 57 at.% which can be carefully controlled by the parameters of the deposition process, i.e., boron carbide concentration, synthesis temperature, and the applied anodic current density, in particular. The Raman spectra of boron doped graphene reveal the additional characteristic boron peaks aside from the traditional graphene ones. The intensity of these boron peaks is shown to be affected by boron concentration in graphene.

Аннотация: CaZr0.9Y0.1O3−δ (CZY) films were fabricated by chemical solution deposition (CSD) from ethanol-based liquid solutions. The films were deposited on single crystals of yttria-stabilized zirconia (YSZ) in (100), (110) and (111) crystallographic orientations. The structural, mechanical and electrical properties of the films have been studied by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), and nanoindentation and impedance spectroscopy methods. XRD and SEM results have shown that the films were polycrystalline. Effect of the substrate orientation on the microstructural, mechanical and electrical properties of CZY films has been examined. The films deposited on (110)-substrates consist of the largest grains; show the highest values of hardness and electrical conductivity. Conductivity of CZY film on (110)-substrates increases with rise in humidity which proves proton transport in the films

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

Аннотация: CaZr0.9Y0.1O3 − δ films were fabricated by chemical solution deposition on single-crystalline YSZ (ZrO2 doped by 10 mol% of Y2O3) substrates. Mechanical hardness and morphology of the films were studied using nano-indentation and atomic force microscopy techniques. Grain microstructure of the films has been shown to depend upon thermal treatment duration and film thickness. Thin films with grains a few times greater than the film thickness have been obtained. It has been shown that thickness of films can be evaluated by comparing of the indentation curves for the clean and coated by the film substrates. Mechanical hardness of the film has been found to be sensitive to the film grain microstructure. Electrical behavior of CaZr0.9Y0.1O3 − δ films studied by impedance spectroscopy strongly depends on the film microstructure.

    The across-plane conductivity and microstructure of SrZr0.95 Y0.05 O3 − δ thin films / L. A. Dunyushkina, S. V. Plaksin , V. M. Kuimov, V. P. Gorelov, S. V. Smirnov // Ionics. - 2013. - Vol. 19, № 12. - P1715-1722. - Bibliogr. : p. 1722 (19 ref.)

Аннотация: The across-plane electrical conductivity of the proton-conducting SrZr0.95Y0.05O3 − δ thin films fabricated by chemical solution deposition on single-crystalline ZrO2 doped by 10 mol% of Y2O3 (YSZ) substrates was investigated using impedance spectroscopy. The average grain size of the films was found to increase considerably with thermal treatment. This change in grain size has a strong effect on the electrical behavior of films. Our results show that the electrochemical performance of the cell is strongly affected by the potential difference at the film/substrate interface. Coarse-grain film microstructure was proved to be preferable for the reduction of both the film resistance and interfacial barrier.
