The paper discusses an alternative method - the synthesis of biomimetic composite coatings on a titanium alloy. With this method of obtaining materials, the bond of the implant with the bone develops due to the biomimetic formation of an active layer of hydroxyapatite on the surface of the titanium alloy. This layer is formed as a result of the transition of calcium ions from the implant material into the intercellular fluid, the composition of which is similar, for example, to the composition of the simulated human body fluid. In this study, we tried to synthesize a biomimetic composite based on a gelatin-calcium-phosphate coating on a titanium alloy VT1-0 and determine its structure, composition, and physicochemical properties. Synthesis of composite coatings on titanium alloy implants consisting of hydroxyapatite powder and 1%, 2% and 3% gelatin was conducted. The samples of titanium implants were immersed in the hydroxyapatite suspension with the addition of gelatin, while the pH value was 7.4, which corresponds to physiological. In the study, a titanium alloy of the VT1-0 grade was used, and its surface was preliminarily subjected to processing: it was polished, etched, and exposed to a powerful ion beam. The XRD data showed that samples synthesized in simulated body solution at different concentrations of gelatin are single-phase and represent hydroxyapatite. It has been established that the crystallization rate depends on the method of pretreatment of the titanium implant surface. A faster growth of crystals was observed on thin sections of polished specimens, while on etched specimens, dendritic growth occurred in bulk defects caused by etching. The consolidation of the composite layer was observed after exposure to a powerful ion beam.

A planar plasma source based on a high-current discharge in a dielectric capillary has been created, which allows the formation of high-speed plasma flows with a density of at least 10−7g/cm3. Using a metal plasma duct, a uniform planar flow was obtained, having a speed of $9 text{cm}/ mumathrm{s}$ and an angle of opening of the plasma jet of ∼ 20°. A switch based on the created planar plasma source made it possible to implement a controlled mode of shunting the inductive load with a mega-ampere current from the discharge circuit of the primary energy storage device.

The field of metamaterials has grown considerably in the last few decades due to the advances in new manufacturing technologies. Metamaterials currently are of interest for a wide variety of applications including damping systems. This work is aimed to evaluate dissipative effect of pentamode metamaterials subjected to dynamic loading. The results of numerical modelling of the mechanical behavior of pentamode metamaterials from alpha titanium alloys are received and compared with available experimental data. The model of inelastic deformation and ductile damage criterion are used to describe the ductility of the unit cell of metamaterials in a wide range of strain rates, temperature and stress triaxiality. A methodology for analyzing the energy dissipation due to inelastic deformation of metamaterials at high strain rates is presented. It is shown that the values of the energy dissipation coefficient during uniaxial dynamic compression of the pentamode metamaterial are 1.5 times higher than for the bulk alloy counterpart.

The effect of irradiation with low-energy helium and krypton ions on the surface structure, hardness, and corrosion resistance of ZrWN coatings was studied. Magnetron sputtering was used to form ZrWN coatings on structural steel substrates. Irradiation was carried out at room temperature and 600 °C. It was shown that the structure and properties of coatings degrade under irradiation with helium and krypton ions. Irradiation temperature affects the degree of degradation – with increasing temperature, corrosion resistance and strength characteristics of the coating decrease.

In this work, thermal behavior and combustion properties of a coal dust of Pavlovskiy brown coal were studied. The investigation was focused on the estimation of time parameters of fine coal particle combustion using the data obtained during the experiments on the constructed laboratory-made setup. The advantage of the constructed laboratory setup is that the experimental conditions are as close as possible to the conditions of the existing boiler units. In such conditions a significant part of the heat flow in the combustion chamber is supplied to the fuel in the form of radiant energy, in contrast to many experimental installations where convection heating is occurred. Experimental research parameters were applied for theoretical and numerical investigation. Calculated time parameters, such as heating-up time, yield and burning time of volatile, and burning time of char were compared with experimental data. Preliminary analysis of our experimental results on combustion of fine coal particles demonstrates that empirical equations for simulation of time-depended coal combustion process can provide reasonable agreement with experimental data.

The propagation of a nonlinear magnetic diffusion wave which arises in an electrical explosion of plane conductors occurring in a current skinning mode was investigated experimentally on a MIG generator (2.5 MA, 100 ns). The magnetic field induction was significantly greater than that necessary for the plate surface facing the electric field to explode. The loads configured as plane conductors were chosen to observe plasma formation on the back side of the plate. It was observed that on this side, under the given experimental conditions, 75 ns after the onset of current flow, a plasma channel formed in the region of the longitudinal axis of the plate. The pattern of channel formation was investigated in relation to the magnetic field strength and the plate width.

The purpose was to study the proliferative activity of bone marrow mononuclear cells (BMNCs) of rats after irradiated by nanosecond repetitive pulsed microwave (RPM). It was found that the irradiated by nanosecond microwave pulses can affect the BMNCs proliferation in vitro. It is important that both stimulation and inhibition of proliferation were observed after exposure. The effect depended on the pulse repetition frequency. The amount of BMNCs increased after exposure to pulse repetition frequency of 13 Hz up to 30% in comparison with a control cells and up to 51% in comparison with a false-irradiated cells. In contrast, there was inhibition up to 40% of BMNCs after exposure to a frequency of 8 Hz, in comparison with a control group.

A coaxial electrode configuration with surface dielectric barrier discharge was designed to generate a cold plasma jet flowing out into the ambient air. A technique for determining the plasma region extension based on measuring average current and applied voltage has been proposed. The capacitance of the system was calculated from measured current and voltage. Using photographic images of the discharge region, the specific capacitance of the discharge system was determined depending on the electric parameters. The obtained values were compared with the calculated capacitance of the given electrode system geometry.
