Degradable implants occupy the significant position in orthopedic industry. Magnesium is an appropriate degradable material due to its good biocompatibility and degradability properties in addition to advantageous mechanical properties. Improving the material quality, especially corrosion resistance and surface active, could be occur through the chemicals and parameters of the Plasma Electrolytic Oxidation process. Voltage reduction could reduce cost involved and make more environmentally friendly. Doubling the concentration of the sodium phosphate worked at low voltage. The surface morphology showed well-developed structure. Obtained coatings were without cracks and with good thickness size. Increasing wettability point to enhancing bioactive properties.

Peculiarities of obtaining and modifying Ba, Zn-containing polymer-silicate thermal stabilizers of polyvinyl chloride have been studied. The influence of macromolecular modifiers on the morphology and surface characteristics of thermal stabilizers is shown. The influence of fine Ba, Zn-containing polymer silicate thermal stabilizers on the processes of destruction (weight loss, thermal effect), physical-mechanical (surface hardness, elasticity) and thermophysical (Vicat softening point) properties of polyvinyl chloride materials is revealed.

The influence of the parameters of a pulsed power supply of a glow discharge and the substrate temperature on the growth kinetics of CVD polycrystalline diamond films have been studied. It was found that an increase in the pulse frequency from 13 to 50 kHz and a decrease in the pulse duty cycle from 90 to 80% promotes an increase in the films growth rate by 1.5 – 2 times. The non-monotonous character of the dependence of the film growth rate on the deposition temperature upon pulsed excitation of a glow discharge is similar to that characteristic by direct current. In the optimal pulse mode the maximum film growth rate is near a temperature of 1050°C. With an increase in the deposition time, an increase in the average growth rate of the diamond film is observed. When the synthesis process lasts more than 6 hours, the deposition rate reaches 11 μm / hour. The power consumption in the pulsed mode of diamond films synthesis is 0.3 kW / μm, which is 3 times lower than when using a DC power source.

Model samples of nerve conductors with incorporated particles of inorganic origin: chitosan (CS), ZnO, Fullerene C60, dopped with Fe3+ ions multi-walled carbon nanotubes (MWCNTs+Fe) were successfully synthesized and investigated. The inclusion of inorganic particles in the alginate (Alg)-based composites reduces hydration (swelling) degree and affects the material’s resistance, leading to a decrease in the electrical conductivity. The MWCNTs+Fe-containing sample shows the highest electrical conductivity, mainly due to iron ions. ZnO and fullerene C60-containing samples have the lowest electrical conductivity due to high density and lower ability to hydrate. The mechanisms of Trp adsorption on the experimental samples were determined with Langmuir, Freundlich, Slips, and Henri isotherms equations. Sips isotherm model, which predicts the heterogeneity of the adsorption system, provides the best correlation of all experimental sample data, and the $text{r}^{2}$ values of about 99% confirm that. The adsorption on the ZnO-containing sample is well fitted to the Freundlich isotherm model (1/n<1), which means that reversible and non-ideal adsorption is favorable. The heterogeneity of the Alg-ZnO surface, as well as the exponential distribution of the active energies sites, takes place.

Using the physico-geometric approach in the thermal programmed desorption mass spectrometry (TPD-MS method), the possibility of indirect estimation of the three-dimensional structure of a multilayer heterogeneous composite of “calcium carbonate (calcite) – protein” type of eggshells of a guinea fowl (Numida meleagris) eggs. The method is based on the difference in rates of thermal decomposition rates of calcium carbonate depending on the peculiarities 3-D micro-, nanostructure of each layer. Increased porosity and reduction in the density of crystallite packing in local areas of the shell is accompanied by a shift of maximum peaks in the complex curves of the dependence of carbon dioxide release during process of thermal destruction (thermograms) in the direction of low temperatures. The TPD-MS makes it possible to determine of quality level and mechanical properties of the eggshells in cases where traditional methods of microscopy don’t give reliable results. Thus, this study shows the presence of reliable structural differences in different areas of the nanocomposite layers of the eggshell of guinea fowl (Numida meleagris), distinguished by increased strength. These experimental and theoretical results can be the methodological basis for the development of a new method for assessing the quality of food eggshells, which is needed to prevent losses and prevent contamination with Salmonella.

Magneto-responsive biomaterials can play a key role in several biomedical applications, from therapeutic to diagnostic. Despite the several efforts for synthesizing and characterizing bioceramics doped with magnetic ions or polymers loaded with magnetic nanoparticles, there is lack of mathematical and numerical models capable of filling the gap between nanomaterial science and engineering. This work reviews and propose numerical, multiphysics models for studying the use of magnetic scaffolds for the hyperthermia treatment of bone tumors and for magnetically targeted drug delivery.

the two series of ferrites were synthesized. The first series was obtained by the traditional method of coprecipitation. The second series was synthesized by the new improved method which was named the coprecipitation with overheating. FTIR spectra had shown the tetrahedral and octahedral metals ions sites, and the XRD pattern confirmed the formation of cube structure with the stable lattice constant of ferrites in obtained nanopowders. The high catalytic activity of all synthesized nanoferrite catalysts in the sodium borohydride hydrolysis reaction was proved. But Nickel ferrites synthesized by a new method of coprecipitation with overheating showed significantly higher catalytic activity in the studied process of hydrogen production. The possibility of nickel ferrite nanopowders using for hydrogen production by hydrolysis of sodium borohydride has been shown and confirmed.

Nanodiamonds (NDs) attract much attention due to their unique chemical and physical properties, and numerous applications in medicine and biology. Nevertheless the problem of their invasion and accumulation in the cells, and mechanisms of their extraction from the organisms are not clear. In this paper a detailed review of literature on biotoxicity of NDs and their influence on cells and tissues is presented. It is shown, the effects are dose- and size-dependent, and depend on the administration type (puerperal, intratracheal, etc.). Besides, the opposite effects (both cytotoxic and non-toxic) have been observed on the same animals by different authors. Radio protective ability and cytotoxicity of the NDs with sizes 210 nm have been studied on rats with different type of administration with food of aqueous suspensions of NDs homogenized by ultrasound treatment followed by X-ray exposition (5.8g, 5 min). It was shown, administration of NDs produce no cytotoxic influence. Radioprotective influence of NDs have also been confirmed.

The theory of the formation of n-n+ transitions in three-layer heterosystems with significant mismatch of lattice parameters of contacting materials exposed to intense laser or radiation irradiation is developed. Within the framework of the developed model, the concentration of conduction electrons was calculated. It is established that the concentration profile of conduction electrons depends on the average concentration of dot defects, the mismatch parameter and the geometric size of the heterostructure.
