The objects of research are: electrolytic deposition of copper and alloys; processes involving the association of dyes and metal-ions in solutions; interparticle interactions in binary and ternary systems; the description of the magnetic structure of nanostructured materials. The aim of the stage is the development of physical and chemical processes, targeted regulation complexation, ionic association, the sorption of chemical and biochemical environments with participation of metal particles, functional and colored organic substances. Progress transformations have been studied with the participation of copper in the electrolytic deposition of copper coatings. The kinetics of chemical dissolution of beryllium bronze was investigated. New solid-phase extractants (aminogels) were obtained for extraction and concentration of radionuclides. Processes association and dissociation of amino acids, dyes in solutions with additions of surfactants and organic solvents was examined. Stoichiometric schemes are described on the interactions between protolytic forms of dyes of different classes in the solution to give an idea of the thermodynamic characteristics of complex formation and dissociation, chemical potentials, osmotic coefficients and activity coefficients of amino acids and their salts in binary and ternary solutions. The concept is presented on a numerical approximation variant of spin waves for an adequate description of the magnetic structure of nanostructured magnetic materials.
