Determination of electronic properties of carbon fibers of other carbon nano- and microstructures and their role in the formation of electronic and tribological properties of hybrid nanocomposites based on phenylone. To determine the electronic and magnetic properties of carbon-induced paramagnetic centers responsible for the luminescent properties of SiO2: C nanocomposites under the conditions of their heat treatment at different temperatures. Identify the factors that influence the relaxation processes of photo-excited carriers in polymer composites with CdS nanoparticles of different sizes and suggest ways to achieve maximum luminescence intensity. To develop a technique for the EPR diagnostics of porous SiC and products formed during electrochemical dissolution in order to use it as a catalyst carrier. To develop a technique for the EPR diagnostics of multicomponent systems of magnetic nanoparticles Cu / CuO and Fe3O4: Gd: B, to fully describe their magnetic characteristics, creating a base for their further use in medicine. popup.description2  The dynamics of paramagnetic properties of high-modulus and low-modulus explosives and their composites based on BSP-7 copolymer has been studied. The correlation between their magnetic and mechanical properties of BSP-7 / Ural composites was revealed; Carbon, which is the relationship between the shape and width of the EPR line and mechanical properties. It is shown that the processes of inhomogeneous oxidation of LF and Cu ensembles lead to changes in the structural (LF aggregation) and magnetic properties of such ensembles. Magnetic resonance imaging methods to monitor the condition and characteristics of such ensembles are among the most effective. On the basis of magnetic resonance studies of the Fe3O4: Gd: B complex, both the general magnetic characteristics of the complex and the contributions of its individual components, in particular Gd, have been determined. The obtained data are an important component of the development of the method of neutron-exciting oncotherapy with the use of complex structures containing Gd and B.
