(1) Development of the scientific basis of the latest methods of synthesis, design and control of the characteristics and properties of nanostructured materials with controlled morphology of nanoparticles, topology and structure of the surface, textural and sorption characteristics, hydrophilic-hydrophobic properties of the surface, which can be applied in industry, medicine, hygiene, perfumery, cosmetics and agriculture. (2) Synthesis of materials using layering, sol-gel and template synthesis and adsorption, chemical, polymerization and geometric surface modification. (3) Development of new biocompatible nanostructured materials and bionanocomposites using supramolecular structures based on biopolymers and medicinal substances fixed on the surface of original and modified nanooxides and composite mineral-carbon and metal-oxide materials. (4) Experimental studies and theoretical modeling of phenomena at the boundaries of the separation of different phases. Determination of the mechanisms of interfacial phenomena for the creation of more effective nanostructured composites. (5) Synthesis of nanooxide-polysaccharide and nanohydroxyapatite-polysaccharide compositions and study of structural and morphological characteristics, thermal behavior and sorption capacity for heavy metal cations (Sr(II), Co(II), Ni(II), Cu(II), Cd (II), Hg(II), Pb(II)), dyes, etc. (6) Investigation of the properties of bentonite clays and various types of lignite as possible components for the production of new hybrid bentonite-coal sorbents with high strength and sorption capacity, as well as the use of such natural production waste as sunflower husks, straw, sawdust, etc. as modifiers, which can be removed from the activation process, in order to increase the degree of porosity, specific surface of materials and sorption capacity for cations or anions of various functional groups of organic and inorganic origin for the purification of industrial process waters from ions of heavy metals and o

 The structure of functional composite systems synthesized has been studied, and the influence of their structure on phenomena at the phase boundaries in different media has been revealed. New information has been obtained that will help to better understand experimental data on phenomena at the boundaries of different phases. Experimental data on the textural and adsorption properties of bentonite with coal sorbents and methods of their regeneration for repeated use in the production process and ensuring their long-term service life in the cyclic mode "adsorption-regeneration" were prepared and analyzed. On the basis of experimental data, the physicochemical and structural-morphological properties of protein/nanosilica systems based on the original and geometrically modified nanosilica were determined. New nanostructured solid matrices based on clay minerals, individual and mixed pyrogenic oxides of silicon, zinc, titanium and plant raw materials have been synthesized. Composite materials are obtained on the basis of polydisperse systems - micron particles of natural clays and nanoparticles of pyrogenic oxides TiO2, ZnO, SiO2 and plant raw materials. The formulations of cosmetics (solid shampoos, beldi soap, solid cream, nail wax), as well as dietary supplements based on the obtained nanocomposites have been developed or improved.
