On the basis of the solution to the coefficient inverse problem of heat conductivity we have proposed a method for determination of thermophysical characteristics of material according to temperature measurement in its depth as an approximation of semi-infinite solid, plate of finite thickness, and plate with a layer of ideal conductor at thermal effect of constant power on their surface. The method does not require experimental data smoothing, serves to remove restrictions for heating mode selection, and increases accuracy of thermophysical parameters determination.

Gas-dynamic and thermal characteristics of the gas flow in the flow part of a small-scale plasma-chemical reactor for trichlorbiphenyl decomposition were calculated numerically. The investigations were performed with no regard to the chemical interaction of the components: in the calculations, the treated substance was replaced by a simulator (water steam), water steam was also used as an oxidant. Mathematical model of the flow is based on the complete system of Navier - Stokes equations in the context of axisymmetric task statement, with due regard to the gas flow swirling. The calculation results enabled us to choose the optimum geometrical parameters of the reactor design.

The paper considers the evolution of turbulent kinetic energy in a turbulent boundary layer perturbed by suction. The results show that the boundary layer equilibrium is altered in a non-linear manner due to suppression of the structures near the wall. The behavior, however, suggests that the wavelength of alteration of the equilibrium of the layer is unaffected by a change in Reynolds number and suction rate.

Formation of a liquid film on the surface of a cylinder with microtexture was studied visually. The effect of microtexture on evolution of waves on the surface of viscous liquid falling over the outer surface of a vertical cylinder under the action of gravity depending on Reynolds number is shown. The phenomenon of microwave formation on the film surface was determined; the size of these waves is comparable with the microtexture pitch.

The use of the products formed in combustion of the mineral part of coal (cenospheres) that are close in the ratio SiO₂/Al₂O₃ to crystalline aluminosilicates of the structural type of rock-forming granitoid minerals, in processing and burying radioactive wastes (RAW) allows one to solve the problems of waste minimization both in nuclear and fuel power engineering. Due to the application of microspehric zeolites and porous materials based on cenospheres of the ash from the combustion of the Kuznetsk coal for solidification of liquid RAW containing cesium and strontium radionuclides, it becomes possible to obtain glass crystal compounds under rather soft conditions (750-900 °С). Under these conditions, mineral-like phases of feldspar and feldspathoids fixing radionuclides in their lattice are formed. The target phases content reaches 66-80 %.

Sorption of methylene blue, vitamin B₁₂ and gelatine on the enterosorbent made of the bast of birch bark from aqueous solutions modeling the medium of stomach and intestines was investigated. The corresponding kinetic curves allowing one to estimate the completeness of the use of the sorption potential of enterosorbent in differentmodel media were obtained. Efficient curative and prophylactic action of the enterosorbent for the therapy of esherichiosis in mice was demonstrated.

Features of physicochemical processing of the natural gas of Eastern Siberia for the purpose of obtaining valuable products are considered. Special attention is paid to the processes based on the microspherical components of energy ash: non-cryogenic process of helium isolation using cenospheres, and the process of oxidative dimerization of methane (ODM) into ethane and ethylene in the presence of ferrospheres. A scheme of natural gas processing taking into account the features of composition and involving the stages of ODM is proposed.

Results of investigations, carried out at the Institute of Chemistry and Chemcial Technology SB RAS, concerning the problem of search and development of methods to synthesize new complex compounds of platinum possessing biological activity are presented. Two series of compounds representing the analogues of cisplatin and oxplatin, respectively, are presented. New efficient synthesis procedures were developed, X-ray structural studies of the majority of compounds were performed. Thernal stability and solubility of compounds were established. The data obtained may serve as the basis for the industrial production and arrangement of the modern physicochemical monitoring of the composition and properties of these preparations.

Results of investigations carried out in the Institute of Chemistry and Chemcial Technology in the area of mastering the technologies for obtaining synthetic solid, gaseous and liquid fuel from the brown Kansk-Achinsk coal are generalized. The technologies under development are based on the processes of autothermal pyrolysis and gasification of brown coal in the reactors with the boiling bed of catalytically active slag, and on the processes of thermal dissolution of coal and its mixtures with carbon-contaiing wastes in the presence of activated iron ore catalysts that provide obtaining liquid fuel and binders for road construction.

Results of the investigation of composition features of brown coal from Siberian deposits and the major factors determining its structural properties are presented. Methods of stimulating destructive reactions of hydrogenation into liquid hydrocarbons by means of preliminary activation tratment and the use of catalysts are considered. Investigation was carried out with different coal samples from the Kansk-Achinsk and Lensk basins; for comparison, the data on brown coal from the large deposit Yallourn (Australia) are described. The general regularities of the changes of structural properties are established, as well as the features of the interaction with solvents depending on the content of ion-exchange cations among which calcium cations are prevailing and play the part of ion cross-links in the structure. It is shown that cation removal with diluted HCl solutions, mechanochemical treatment and irradiation with accelerated electrons under optimal conditions allow one to enhance the activity int eh interaction with solvents and to elevate the reactivity during hydrogenating destruction into liquid hydrocarbons.
Results of the investigation of the effect of conditions of mechanochemical treatment of iron ore concentrates on their phase composition and parameters of the fine crystal structure are presented. The conditions of the preparation, on this basis, of dispersed active hydrogenation catalysts providing thorough decomposition of the organic mass of brown coal to form liquid hydrocarbons were developed. The individual and group composition of the obtained light-coloured hydrocarbon fractions of coal hydrogenates was determined. The data were compared with the composition of the corresponding fractions of oil from the major promising deposits of Eastern Siberia. Suitability of liquid coal hydrogenates for obtaining synthetic motor fuel, other oil products and their use as petrochemical raw material was substantiated.
