Use of Alternating-Current Plasma Torch for Processing Potentially Hazardous Substances
High Energy Chemistry - Tập 52 - Trang 319-323 - 2018
A. A. Safronov, O. B. Vasil’eva, Yu. D. Dudnik, V. E. Kuznetsov, V. N. Shiryaev, D. I. Subbotin, N. V. Obraztsov, A. V. Surov, V. E. Popov
The decomposition of tetrachloromethane and tetrafluoromethane by air plasma in the presence of methane has been studied using an ac plasma torch of up to 500 kW power with rail electrodes. Methane reacts with air in the partial oxidation mode to form hydrogen, which reacts with a halogen to produce the hydrogen halide.
Conformation of radicals in a γ- irradiated linear perfluoroalkane at 77 K
High Energy Chemistry - Tập 34 - Trang 145-150 - 2000
S. R. Allayarov, I. M. Barkalov, A. I. Mikhailov
The principal geometrical parameters of the carbon skeleton of ~CF2CFCF2~ and ~CF2CF2 radicals at 77 K show good agreement with spiral configuration of a perfluoroalkane molecule in crystal. The conformations of radicals resulting from fluorine atom abstraction or C-C bond cleavage are determined by minimum of bond rotation potential energy in a linear perfluoroalkane helix. The analysis of the sp...... hiện toàn bộ
Effect of Surfactants on Shape of Gold Nanoparticles
High Energy Chemistry - Tập 54 - Trang 308-315 - 2020
M. G. Spirin, S. B. Brichkin, E. S. Yushkov, V. F. Razumov
In a binary mixture of cetyltrimethylammonium bromide (CTAB) and benzyldimethyltetradecyl ammonium chloride (BDTAC), gold nanorods with a maximum absorption of longitudinal plasmon resonance up to 1600 nm have been obtained. It has been shown that the shape of the growing nanoparticles is determined by the CTAB/BDTAC molar ratio. The optimal conditions have been found for the synthesis of homogene...... hiện toàn bộ

Influence of Irradiation with Helium Ions on the Surface Properties of Kynar Polyvinylidene Fluoride
High Energy Chemistry - Tập 55 - Trang 502-506 - 2021
I. F. Shaimukhametova, S. A. Bogdanova, S. R. Allayarov, D. A. Dixon
The surface energy characteristics of polyvinylidene fluoride irradiated with accelerated helium ions have been investigated. The bombardment of the polymer with helium ions leads to an increase in the acid–base component of the surface free energy and surface polarity due to the appearance of polar functional groups in the surface layer. Determination of the acidity parameters of the irradiated p...... hiện toàn bộ
Reduction of Boron Trichloride in Atmospheric-Pressure Argon–Hydrogen Radiofrequency Induction Plasma
High Energy Chemistry - Tập 53 - Trang 246-253 - 2019
R. A. Kornev, P. G. Sennikov, L. V. Shabarova, A. I. Shishkin, T. A. Drozdova, S. V. Sintsov
The main operating modes of a radiofrequency induction plasma torch with a vortex stabilization of the atmospheric-pressure gas discharge at have been studied in an argon-hydrogen mixture in the range of Ar/H2 = 12–4. The dependences of the electron temperature Te and number density ne on the Ar/H2 ratio have been experimentally studied. It has been found that the electron temperature and concentr...... hiện toàn bộ
A Microwave Photoconductivity and Photostimulated Flash Luminescence Study of Silver Chloride Photolysis
High Energy Chemistry - Tập 38 - Trang 264-268 - 2004
E. P. Tat'yanina, A. N. Latyshev, G. F. Novikov, O. V. Ovchinnikov, M. S. Smirnov
The combined effect of chemical surface treatment (HCl, AgNO3) and preliminary UV irradiation on the properties of electron trapping sites and luminescence sites in silver chloride grains was studied using the microwave photoconductivity and photostimulated flash luminescence techniques. It was found that the properties of the sites strongly depended on a sample history and surface treatment condi...... hiện toàn bộ
