ZnO photocatalytic thin films deposited on a glass substrate are obtained by chemical spraying technique, and they are active in the visible light spectrum. Optical studies have shown that ZnO thin films doped by nickel impurities absorb visible light at wavelengths from 400nm to 600nm. At the same time, this absorption rate increases with the increase of concentration of nickel impurities. At high concentration (5%), the absorption of light is reduced in the visible area, but after heat treatment at 6000C the light absorption in these samples improves, which allows us to conclude that the observed effect is caused by a violation of the homogeneity of the distribution of nickel impurities and the creation of agglomerates. Decoration of ZnO thin film surfaces by silver clusters improves light absorption, as it happens to the nanopowders, but in the case of thin films, this effect is much smaller. Experiments on methylene blue determine the significance of photocatalytic activity in the visible area of sun irradiation of ZnO thin films containing nickel impurities, which are obtained by chemical spraying technique.

The low temperature heat capacity measurements on LSCO samples containing Zn impurities have been performed by means of pulsed differential calorimetry technique. The interpretation of the Zn-concentration dependence of the residual γ-coefficient in the linear temperature part of Cel(T) at T≪Tc is consistent with a model based on the assumption of the d-wave symmetry of the order parameter of these superconducting copper oxides.

The competitive method of fabrication of thermo-absorbing meso- and nanosized magnetic particles was developed. Applications of high-dispersive magnetic particles could include information storage systems, biomedical fields, targeted delivery of drugs for cancer treatment, sensors, etc. By means of electroless deposition of nanoclusters on high-dispersive powder-like semiconductor TiO2 (anatase), some problems of fabrication of visible light-responsive photocatalysts are overcome or mitigated. A new method of size selection of pure TiO2 particles and micro-, meso- and nanocrystal-coated powder-like semiconductor photocatalysts with aim obtain of a uniform size distribution was developed. Catalysts Pd/γ-Al2O3, reduced in hydrogen flow, compare well with platinum catalysts by the activity in relation to breaking of bonds between carbons.

The low-temperature heat capacity of cuprates(La2CuO4,La2−xMxCuO4(M = Sr, Ba) and Nd2−xLaxCuO4) is studied in the temperature range 2–45 K by using pulsed differential calorimetry. It is found that the coefficient of the linear term of heat capacity remains unchanged over the entire temperature interval under investigation. The special role of La atoms in the formation of the anomaly in the acoustic region of the phonon spectrum of these compounds near 6 meV is demonstrated. This anomaly is connected with peculiarities in the interaction of these atoms with the environment.
