Study of the nature, properties, reactivity and functional activity of the modified surface of nano-sized materials. Adsorption, catalytic and electrochemical processes occurring at the phase separation boundary are highly effective and are implemented in the purification processes of gas and liquid media, in the production of high-purity substances, in industrial and environmental catalysis, in the development of effective current sources, in environmental protection and medicine. The solution to many technical and materials science problems is determined by the creation and use of highly active materials for targeted purposes. The decisive influence on the course and efficiency of interphase heterogeneous processes is exerted by the specific surface area of materials, the composition and structure of the surface layer of adsorbents. Therefore, the development of physicochemical foundations for the synthesis and modification of the surface of carbon and inorganic nanomaterials is an urgent task of creating functionalized systems for targeted purposes. popup.description2 Strategies for imparting of enzyme-like properties to carbon nanomaterials, namely: regulation of nanoparticle morphology, size control, surface modification with functional groups, doping and co-doping with heteroatoms of metals and nonmetals were identified. It was established that the amorphous ultrathin Ti-B coating contributes to the formation of a more passive rigid-flexible SEI layer with self-adaptive deformation properties, which contributes to an increase in the Coulomb efficiency and improvement of the structural stability of aluminum foil anodes during long-term cycling. High-purity thermally expanded graphite was obtained, with a carbon content of 99.75-99.85 wt. % by combining the synthesis of oxidized graphite and its chemical purification into one process. The ketenization regularities for the nanoscale silica-induced pyrolysis of glyceryl trimyristate, the main component of oilseed processing waste, have been established, which paves the way for the development of environmentally safe technologies for processing renewable biomass into products with high added value, biofuels, and valuable chemical products. The carbonization conditions of lignin-containing renewable raw materials have been optimized, which allows obtaining new porous carbon sorbents with high adsorption capacity towards pollutants of organic and inorganic nature. An economically advantageous and environmentally friendly approach for the synthesis of zeolitic imidazolate compounds with cuboidal particle morphology containing cobalt, cobalt/zinc and zinc atoms was proposed. The physicochemical properties of cross-linked β-cyclodextrin-containing polymers with different molar ratios of β-cyclodextrin: hexamethylene diisocyanate were synthesized and investigated. The ability of deoxyribonucleic acid immobilized on the surface of nanocrystalline titanium dioxide to interact with the cytotoxic anthracycline antitumor antibiotic doxorubicin was investigate Product Description popup.authors Ignatenko Oleksandr M.
