The most stable oxide of the vanadium oxide family is V2O5. A lot of research effort is focused on it because it has a multitude of functional applications. Here we report on how the heat treatment (600°C, 5 h, air) affects the microstructure and hence, the band gap of V2O5. The V2O5 powders, initially obtained by simple thermal dissociation (500 °C, 3 h, air) of ammonium metavanadate, followed by heat treatment of pellets; were studied. The structural and optical studies performed using X-ray diffraction (XRD), FESEM and UV-Vis techniques, provide uniquely interesting results which indicate the possibility of band gap tuning by controlling the microstructure.

The significant attention is paid to the development of new composite materials which can be widely used in the manufacturing and repairing details and their components in different branches of industry including water transport. Intensity of cargo transportation by the water transport, an increase in the frequency of loading operations, their operation under the influence of aggressive environments put forward requirements for the improvement of indicators of resource saving of vehicle units and increasing the inter-resource period of work. In this context, the epoxy composite materials are one of the most promising materials, which meet the requirements of modern transport industry, due to their performance characteristics, which in most cases are better than traditional metals and alloys. Therefore, in the work, the physical and mechanical properties of composite materials with nanodispersed additives based on the epoxy-polyester matrix, were studied. An oxidized nanoparticle additive and pyrogenic silicon dioxide were used as fillers. It was found that epoxy-polyester composites are characterized by improved properties at significant amount of the oxidized nanoparticle additive. An optimal ratio of the epoxy-polyester binder and additive was 100:0.06-0.08 pts. wt. It was ascertained that the introduction of pyrogenic silicon dioxide leads to a decrease in values of investigated properties of composite materials. In particular, the fracture surface of epoxy-polyester materials was analyzed with the method of optical microscopy. It was stated that composite materials filled with pyrogenic silicon dioxide were characterized by high residual stresses. The presence of low amount of fracture lines on the surface of composite materials filled with nanodispersed additive was revealed. Therefore, composite materials with nanofiller are characterized by higher resistance for fracture and impact loads.

The present paper reports a comprehensive first-principles calculation of the structural, electronic and thermophysical properties of B1, B2 and B3 phases of AlSi (Silumine) alloy using plane-wave pseudopotential density functional theory (DFT). PAW type pseudopotential with the exchange correlation of Perdew-Burke-Ernzerhof (PBE) are used to compute properties of B1, B2 and B3 phases of AlSi alloy. Our computed equilibrium lattice constants are in excellent agreement with the reported results. To investigate the structural phase transitions beween different phases of AlSi alloy, volume dependence of energy and pressure dependence of enthaply are studied for B1, B2 and B3 phases of AlSi alloy. Further, the electronic band structure along with the total electronic density of states of B1, B2 and B3 phases of AlSi alloy are calculated at the ground states. Behaviour of the total electronic density of states of B1, B2 and B3 phases of AlSi is also studied with the increase in pressure up to 100 GPa. In addition, various finite temperature/pressure thermophysical properties such as the room temperature thermal equation of state, isothermal bulk modulus, coefficient of thermal expansion, heat capacity at constant volume and pressure, Debye temperature and Grüneisen parameter are computed for B1, B2 and B3 phases of AlSi alloy using quasi harmonic Debye model. Conclusions based on the structural, electronic and thermophysical properties of B1, B2 and B3 phases of AlSi alloy are summarized.
