Samples of the solid component of welding aerosol (SCWA) obtained as a result of metal welding by two types of electrodes, ANO-4 and TsL-11, were characterized by elemental analysis, X-ray diffraction phase analysis, IR spectroscopy, and pH-metry. Both SCWA-ANO-4 and SCWA-TsL-11 samples purified the ozone-air mixture (OAM) with ozone concentration of 1.0 mg/m3 to the concentration values below 0.1 mg/m3 (maximum permissible ozone concentration, MPCO3).

The work deals with the study of the phase and structural behaviour of mixed europium cobaltites-ferrites formed in the EuCoO3-EuFeO3 pseudo-binary system. Formation of a continuous solid solution EuCo1-xFexO3 with orthorhombic perovskite structure (GdFeO3 type, space group Pbnm) has been revealed. Crystal structure parameters of the mixed europium cobaltites-ferrites have been established by the full profile Rietveld refinement. Based on the analysis of structural parameters, an influence of the cation substitution on the deformation of the orthorhombic perovskite structure in the EuCo1-xFexO3 series has been established.

The impedance spectra of silicon oxide nanocomposites of porous silicon is investigated in 25 Hz - 1 MHz frequency range. The different dispersion of electrical capacity in different frequency bands and complex relaxation processes that affect the electric transport properties of nanocomposites were revealed. Based on the analysis of spectra of thermal stimulated depolarization it was shown that oxidation of the surface of porous silicon nanocrystals gives rise to changing the density of states in different energy ranges.

The 3 inch in diameter (TmBi)3(FeGa)5O12 epitaxial films with thickness up to 60 μm were grown by liquid phase epitaxy method. The Bi2O3, Bi2O3-B2O3, Bi2O3-B2O3-Na2O and Bi2O3-B2O3-CeO2 fluxes were used. The conditions of orthoferrite and garnet primary phase crystallization and optimal growth strategy were determined. It was found that the surface morphology strongly depends from film-substrate lattice mismatch. All films with mirror surface demonstrate high Faraday rotation and low saturation magnetization which are suitable for magneto-optic applications.

We report the data concerning the optically pumped laser generation in the ZnO microprisms at room temperature. The ZnO microprisms were grown on the single crystal (100) silicon substrates by a solid-vapor-phase process. Laser effect was observed when the optically pump power was higher than 685 kW cm-2 at room temperature.

Mesoporous maghemite γ-Fe2O3 was obtained by thermal decomposition of iron citrate xerogel hydrate. The influence of precursor molar concentration and calcination temperature on the material phase composition, morphology, crystalline and magnetic microstructure, surface condition and optical properties was studied. The model of mesoporous γ-Fe2O3 formation is proposed. Obtained γ-Fe2O3 was tested as cathode material for lithium power sources. Increase of lithium power sources specific capacity and energy with the samples specific surface area enlarging is fixed. Specific energy is 180-200 W·h/kg at the discharge rate 1.0 C. Two kinetic processes are observed during discharge processes: lithium accumulation at the cathode material/electrolyte interface and diffusion of lithium ions into the material crystal structure. The diffusion coefficients of lithium in the cathode material on the different stages of discharge process are calculated.
