In the study, the isothermal thermogravimetric analysis (TGA) of hydroxyapatite synthesized in gelatin matrix (HAG) has been performed. 3 wt.% HAG samples were synthesized from the solution simulating the human extracellular fluid (SBF). X-ray diffraction and IR spectroscopy were used to determine the composition. Dur…
In this paper features of the structure formation of nanoscale coatings (TiN)–(AlN)– (Ti–Al–N) in the vacuum arc discharge plasma are considered. The composition and structure of the formed nanoscale coatings are studied. The main factors influencing the quality of the formed coatings are shown.
The SIMMER family of codes is applied for safety studies of sodium fast reactors and reactors of other types. Both neutronics and fluid-dynamics parts of SIMMER are under development. In the paper new neutronics capabilities are presented. In particular developments for neutron transport solvers and a new technique fo…
Design of the high-power DC supply quite logically based on the required electrical parameters and expected or defined operating conditions. A prerequisite trouble-free operation is also the correct choice of construction materials. Both in terms of mechanical strength and stability, and in terms of thermal load. The…
The results of the developing the library of uncertainties of radioactive decay data in the ABBN data library format are described. Different evaluations of uncertainties were compared and their effects on the results of calculations of residual energy release were determined using the test problems and experiment. Ta…
In this paper we propose a method of using neutronic calculation code CORNER to the analysis of experiments on the protection of fast neutron reactor and CNFC equipment. An example of Winfrith Graphite Benchmark experiment calculation using this approach is presented. This task can be considered as one step in the gen…
The aims of the research to were know performance of DSSC using the dye of Zingiber, Cinnamomum, Curcuma, and Oryza as a photosensitizer with a variation of dye deposition area with spin coating techniques.The structure of the samples as a sandwich consisting of the working electrode (TiO 2 ), dye, electrodes of plati…
Hydrogels are an ideal medium for the expansion of cells in three dimensions. The ability to induce cell expansion and differentiation in a controlled manner is a key goal in tissue engineering. Here we describe a detailed method for producing hydrogels from soft tissues with an emphasis on adipose tissue. In this met…
Due to the superior advantages of high energy conversion efficiency, high brightness, high reliability, controllable color properties, long lifetime, and ease of miniature and digitalization, GaN-based light-emitting diodes (LEDs) are regarded as the next generation solid state lighting sources to replace the conventi…
This article represents the results of computational and experimental research of liquid-metal research reactor control rod kinematics. In this research liquid-metal coolant (sodium) was simulated by water. Investigation of control rod scram-mode movement duration and investigation of velocity of movable parts near th…
In this paper influence of the bubble layer on the transmission of the acoustic waves through the three-layer barrier placed in the water at various angles of incidence is investigated. Barrier consists of a layer of gel with polydispersed air bubbles limited polycarbonate layers. It is shown that the presence of bubb…
This thesis describes the synthesis and characterisation of new iron(II) spin crossover (SCO) compounds containing new 2,2’-dipyridylamino-substituted s-triazine ligands. The compounds have been comprehensively characterised using a range of techniques, with the aim of drawing structure-function correlations between m…
The evaluation of the developed computational models to determine the cracking effort in the short reinforced concrete beams with shear span is changed from 0.25 to 1.5, based on experimental data. To select and justify the final decision analyzed three options for building a computational model of the core.
The possible role of existing thorium reserves in the Russian Federation on engaging thorium in being currently closed (U-Pu)-fuel cycle of nuclear power of the country is considered. The application efficiency of thermonuclear neutron sources with thorium blanket for the economical use of existing thorium reserves is…
A periodically corrugated interface between vacuum and a high-index dielectric medium supports a p-polarized leaky surface electromagnetic wave whose sagittal plane is perpendicular to the generators of the interface. This wave is bound to the surface in the vacuum region, but radiates into the high-index dielectric m…
Information about the change of thermal properties of the fuel elements needed for a successful and safe operation of the nuclear power plant. At present, the existing amount of information on the fuel thermal conductivity change and "fuel-shell" thermal resistance is insufficient. Also, there is no technique that wou…
Effect of annealing at temperature range of 573–823 K on stability of the ultrafine-grained structure of the Zr-1wt.%Nb alloy was studied by methods of transmission electron microscopy. Growth kinetics of grain–subgrain structure elements of alloy was investigated.
The solubilities of sulfamethoxydiazine in methanol, ethanol, 1-propanol, 2-propanol, acetone, and chloroform have been determined in the range 293.15–323.15 K by a static equilibrium method. The calculated results show that the correlation of the Apelblat equation for measured systems has less deviation than that of…
The following work describes means of nickel dry-powder developer manufacturing by plasma-electrolytic dispergating. For that purpose, a plasma-electrothermic device was developed that allows to manufacture dry-powders with wide range of parameters. Technical conditions for nickel dry-powder developer manufacturing by…
Hydrodynamic processes taking place during the motion of liquid droplets and the formation of a liquid film flowing over surface of a horizontal tube are considered. Mathematical modelling of motion of two-phase medium is based on the Lagrangian approach. The results of numerical calculations of the liquid film thickn…
