Abstract
Fundamental factors of the formation of scientific and philosophical world view of the great Russian scientist and thinker M.V. Lomonosov (1711-1765) are exposed. Correlation between scientific and philosophical reasoning in his creation work is analysed. His contribution to developing the national philosophy is shown.

Abstract
Traditional and improved methods of producing composite supports modified with nanolayers of fluoropolymers and polyanilines are reviewed. The methods provide the localization of the polymerization process at the surface layers of the carrier and additional functionality of the produced nanosystems. The effectiveness of the obtained materials in different fields of bioseparation and bioanalysis has been demonstrated

Abstract
The prospects of using macromolecular nanoparticles as a part of polymer nanocomposites are considered. It is shown that introduction of these nanoobjects into polymers will enable investigating many fundamental problems connected with nanocomposite obtaining, estimation of their structure and properties, formation conditions

Abstract
Review of results of quantum-chemical calculations of potential energy surfaces performed for several families of elementary reactions: 1) successive dehydrogenation of complex alanates of alkali and alkali-earth metals; 2) dissociative adsorption of hydrogen, methane and ethane molecules onto doped aluminum clusters Al@XAl11 with dopants X = B, C, Si, Ge, Li, and Ti; 3) conversion of mеthane into methanol in the presence of oxoferrylporphyrine complexes of (Fe=O)(P)(NН2) type.

Abstract
The paper considers a number of mathematical models of chemical and chemical-engineering objects that use the concept of infinity. We allocated almost unrealizable processes, in the simulation of which infinity shows itself as a phantom. We considered also real processes that achieve the equilibrium state in a finite, but rather long time.

Abstract
Two different flow sheets of extractive distillation for separation of acetone - methanol various composition mixture with water as the extractive agent in the traditional two-column complex and in the partially thermally coupled columns is compared. It is shown, that the complex column provides economy of heat on 11.2-19.6%.

Abstract
The thermal and chemically initiated thermal rearrangements of dicarba-nido-undecaborates was explored by computational chemistry. It was shown that the kinetic stability of dianions of these compounds is reduced in the series 2,9 > 7,8 > 1,7 > 2,4 > 2,8 > 1,2 >2,7 > 2,3.

Abstract
The results of styrene oxide epoxide cycle cleavage by diamines were summarized. The effect of solvent on regioselectivity in the reaction of N,N-diethylene diamine was studied. It was established that the ratio of products correlates well with polarity parameters ЕТ and АN of pure solvents.

Abstract
A methodology for immobilization of zinc oxide nanoparticles in polystyrene microspheres was developed. It includes the synthesis of stabilized zinc oxide nanoparticles and polymerization of styrene under conditions that enable carrying out the formation of adhesive contacts of nanoparticles in the polystyrene matrix.
