Researches in plasma methods for isotopes separation and analyze of the results were done. Results show high values of separation coefficient for intermediate products during the last years. It is shown by us, that these factors will be considerably reduced in the subsequent plasma processes and a way of freezing of high value of factor of division of isotopes

Chemical processes are often connected with use or formation of condensed dispersed phase (CDP). Dispersed particles can change mobility of charges, as well as other parameters of the low-temperature plasma. The aim of this work is to study the effect of magnetic field on the processes of dispersed particles formation in argon-oxygen plasma containing iron and carbon atoms at atmospheric pressure. The equilibrium composition of iron and carbon atoms containing mixture simulated at temperatures of 1000-5000K for optimization of the plasma-forming gas composition. It is shown that in case of oxygen excess, the CDP particles contain only iron oxides. The literature data about the phase transition processes in a low-temperature plasma, as well as the data about the processes with participation of ferromagnetic particles in a constant magnetic field analyzed. The results of investigations of the dispersed particles forming in argon-oxygen plasma of arc discharge in the presence and in the absence of the magnetic field are shown. The formed disperse phase was deposited on the substrates and studied by the electron microscopy and X-ray methods. It was found that with the lack of oxygen the size of the iron-oxide particles created in the arc discharge containing iron and carbon is affected by magnetic field: in a magnetic field of 10 mT the particles are larger than in its absence

The dust collection methods and apparatus, as well as heterogeneous system monitoring methods and devices were considered. The disperse particle counter was developed and tested. Shown that particle counter makes it possible to register a disperse phase presence by mass concentration over 310-14 g/m3 and to estimate a dust particle dimensions

It is known that transmission coefficient of quartz glass containing the same amount of 28Si and 30Si in the silicon optical fiber is lesser than in commercial LEDs for telecommunications. Therefore it is topical to develop the method of optical glass formation with specified isotope composition in the core and in the shell. The article provides an analysis of physical and chemical processes occurring at the formation of quartz optical fiber blanks by vapor deposition from the gas phase. It is shown that the part of the silicon tetrachloride oxidation stages passes through the radical processes. Therefore for quartz glass formation with specified isotope composition it is possible to use the paramagnetic phenomena caused by the external magnetic field in a high-temperature flow at the quartz glass chemical deposition from the vapor phase. In this case alloy additive using is not necessary. Alloy additives can form density inhomogeneities in the glass. Simultaneous silicon glass formation and silicon isotope separation process bring to significant reduction of the fiber cost in comparison with isotope-enriched materials using. The permanent magnets can be used for magnetic field formation at existing process units

The results of the research of wastewater treatment including pre-ozonization have been presented. The suitability of wastewater pre-barbotage in the storage tanks has been shown. Addition of ozone in small quantities (0,2 ÷ 0,02 g/m3) can improve the wastewater treatment results in the aeration process. Addition of ozone in small quantities doesn’t lead to the significant energy consumption at once. The treated wastewater transparency increases to 50 cm depth

The scientific publications review about the physicochemical properties of pure water and water solutions activated by a microwave radiation was made. The convincing evidences of the water structure changes in the microwave were submitted

In the present work description of the structure of atomic and nanocomposite (NC) levels of crystalline materials which differs from the previously accepted is done

The steady increase in demand for isotopes requires the development of methods to increase the efficiency of isotope separation technologies. Methods of isotope separation based on thermodynamic differences of isotopic forms of the molecules don't require significant investment, but characterized by a low rate of exchange. It's known that the magnetic effect leads to a change the vibrational frequency of the molecules, and therefore their thermodynamic parameters. The change increases the thermodynamic parameters, including the exchange rate. The results of the experimental determination of the thermal effect of dissolving the salts of NaCl, KCl, CuSO4, sodium amalgam decomposition by distillate in a magnetic field and without field were shown. Magnetic interference can have a significant effect on the amalgam exchange method which was shown by quantum and mechanical analysis of the results

The results of development of the experimental stand for studying of ultradisperse heterogeneous systems in time are represented. The possibilities for registration of the experimental factors of refraction which allows to obtain the data about system granulometric structure are submitted

The cluster structure in pure water (distilled) and water salt solution was considered. The experimental methods of the structural units’ registration in water were analyzed. It is shown that the clusters influence on water properties is insignificant by salt concentration more than 10-5 mole
