radiation protection nanocomposite material
dielectric permeability
B-radiation
Composite materials based on thermoplastic matrices from LLDPE, PP, and metallic nanoparticles were obtained by the method of mixing in a polymer melt. Methods of thermal analysis and dynamic mechanical analysis were used to analyze thermal stability of the composite materials
obtained and their physicomechanical properties are studied. Composite materials of the type under consideration display radiation protection properties against β-radiation. High correlation of the passing β-radiation and relative dielectric permeability of the composite material based on the thermoplastic polymer matrices with a metal-containing filler was found.

discrete fibers
The influence of the MoS2 and Mg3Si4O10(OH)2 dispersed fillers and synthetic discrete fibers on the tribological properties of epoxy composites was investigated. An analysis of the curves for the dependence of the operating temperature and friction coefficient of epoxy composites on the fillers content and traversed friction path make it possible to reveal the optimal weight ratios of fillers in material with improved operating characteristics. The mechanism underlying the wear of epoxy composites has been substantiated. The process of formation of a lubricant film of significant thickness due to the synergistic interaction of disperse particles and discrete fibers with the matrix friction products was studied, which additionally increases the load capacity and reduces the mass intensity of the wear of composites.

In the present work we investigate singular effects of the CO2 laser on different ceramic composite mixtures based on boron carbide with addition of different elements. The microstructure of samples at different velocities of laser treatment is compared. The comparison is made of produced microstructures and of ceramics produced by traditional sintering and hot pressing techniques.

Casson nanofluid
heat and mass transfer
Nanofluids, as regards their marvellous enhancement in thermal conductivity, have become useful in several industrial and medical applications. This study presents an analysis of flow, heat and mass transfer for unsteady nanofluid flow through orthogonally moving porous disks. The
Buongiorno theoretical phenomena of nanofluids subject to heat and mass transfer of nanoparticles have been designed mathematically for orthogonally porous disks. The fluid is thought to be non-Newtonian, whose flow is described by the mathematical model of a Casson fluid. Governing
partial differential equations (PDEs) are reduced to nonlinear ordinary ones which are solved numerically
by utilizing the shooting technique. The influence of some parameters on the velocity and thermal distributions with physical quantities like skin friction coefficient, Nusselt and Sherwood numbers has been studied through graphs and tables.
