Main Results
  • During experiments on irradiation of methane-containing mixtures by pulsed electron beams and non-self-sustained discharges initiated by beams a possibility of methane conversion by pulsed electrophysical methods with specific energy expenditures ~5.6 eV/molecule without a significant heating of the processed mixture has confirmed. Assumptions about high values of forming hydrogen concentration (about a half from converted methane quantity) have confirmed experimentally. This value is about 10 times higher than in the case of the use of continuous electron beams.

  • Investigation of conversion of some organic compounds under influence of pulsed electron beam of nanosecond duration has carried out. Investigation of processes on the border of phases Уgas / surfaceФ has executed on example of styrene. The use of a high-sensitive method of chromatomass-spectrometry has allowed to determine that the most probable process of styrene conversion in oxygen-containing gas mixture are reactions with formation of epoxidic intermediate. In the case of the absence of oxygen the main process is a formation of polymer.

    Dependency of styrene concentration

  • On example of investigation of interaction of pulsed electron beam with some haloid-hydrocarbons (chloroform, tetrachlorocarbon, etc.) it is shown that the main process is a separation of haloid atom with a formation of products of molecules sewing-up in dimer-like compounds. Since the haloid in atomic state is formed, a system Уtetrachlorocarbon Ц electron beamФ can be used as an effective halogenying agent.

  • On example of some organic compounds (acetone, benzene, chloroform, tetrachlorocarbon, acetonitrile, hexane, etilacetate) a correlation between mass-specter of organic compounds and products of its radiolysis under influence of pulsed electron beam of nanosecond duration has found and investigated. Obtained analogies make it possible, with the use of extensive base of mass-specters of compounds, to predict a products of its conversion under influence of electron beam and to obtain important information about radiation stability of organic compounds.

  • During processing of nickel target by nitrogen ion beam a growth of trinickel nitride on free cool surfaces in a form of pointed needles, thread-like fibres, and lamellar layers. Such forms of trinickel nitride were not obtained by plasma methods earlier. Peculiarities of synthesis in conditions of plasma chemical interactions at low pressures are formation of a single form of nitride and low temperatures of target and surfaces, where the growth was observed.
