Effectiveness of the third body in the direct recombination of ions
Russian Journal of Physical Chemistry B - Tập 8 - Trang 261-271 - 2014
E. V. Ermolova, L. Yu. Rusin
The dynamics of the three-body recombination of the Cs+ and Br− ions with the formation of products with the lowest internal energy in the presence of the neutral atoms R = Hg, Xe, and Kr as third bodies is studied. The efficiency of the process is characterized by the effectivity function, which represents the dependence of the internal energy of the nascent molecule on the ion encounter energy a...... hiện toàn bộ
Anomalous diffusion in the dynamics of complex processes
Russian Journal of Physical Chemistry B - - 2009
S. F. Timashev
It is shown that complex signals represented in the form of time series of measured dynamic variables can contain chaotic components whose time changes can be described as anomalous diffusion processes. To determine the parameters of such processes, procedures for the extraction of low-frequency and highest-frequency flicker-noise components, which are flicker-noise spectroscopy characteristics, s...... hiện toàn bộ
Dependence of the Knock Threshold of an H2-Air Mixture With Small Xe Additives
Russian Journal of Physical Chemistry B - Tập 15 - Trang 250-258 - 2021
G. A. Atanov, V. M. Ezhov, S. V. Kulikov, O. A. Papanov, N. A. Chervonnaya
The effect of a small addition of Xe on the conditions for the occurrence of detonation in an incident shock wave (SW) with a change in its intensity is studied. The experiments are carried out in a shock tube (ST) with mixtures (75 – q)% H2 + 25% air + q% Xe, where q = 0, 0.25, and 0.5. The addition of Xe leads to a shift in the detonation threshold to the region where the conditions are more unf...... hiện toàn bộ
Structure and internal dynamics of nanodroplets in dilute solutions of chiral gelators
Russian Journal of Physical Chemistry B - Tập 9 Số 4 - Trang 667-679 - 2015
Д. В. Зленко, С. В. Стовбун
Effect of Oxidation of Fluorohydrocarbons and Fluorocarbons on Their Characteristics as Gas Combustion Suppressing Agents
Russian Journal of Physical Chemistry B - Tập 13 Số 2 - Trang 291-296 - 2019
Kopylov, S. N., Gubina, T. V.
The combustion of some fluorohydrocarbons (FHCs) and fluorocarbons (FCs) in oxygen was studied in a closed vessel at initially room temperature and atmospheric pressure. The chemical mechanism of oxidation of these compounds was discussed. To improve the characteristics of fluorinated compounds as gas combustion suppressing agents, an oxidation inhibitor should be introduced in them. After the add...... hiện toàn bộ
The role of the second order Jahn–Teller effect in the thermal reactions of ethylene
Russian Journal of Physical Chemistry B - Tập 10 - Trang 884-889 - 2017
I. V. Bilera, Yu. A. Borisov, N. N. Buravtsev, Yu. A. Kolbanovsky
The UV absorption spectrum of ethylene during the pulse heating of an ethylene–argon mixture to prepyrolysis temperatures in the range 950 < Т < 1285 K was studied by kinetic spectroscopy in a free-piston adiabatic compression unit. New intense light absorption bands were found at 210 < λ < 260 and 440 < λ < 490 nm. Ab initio quantum-chemical calculations of the mechanism of the thermal cis-trans ...... hiện toàn bộ
Detailed kinetic mechanism of the multistep oxidation and combustion of isopentane and isohexane
Russian Journal of Physical Chemistry B - Tập 9 - Trang 933-939 - 2016
V. Ya. Basevich, A. A. Belyaev, S. N. Medvedev, V. S. Posvyanskii, S. M. Frolov
A detailed kinetic mechanism was developed for the oxidation and combustion of isopentane (2-methylbutane) and isohexane (2-methylpentane), which describes both high-temperature reactions and a multistep process in the region of low temperatures. These hydrocarbons were chosen because they, together with isobutane, are the first members in the homologous series of isomerized alkanes and a higher m...... hiện toàn bộ
Quantum-Chemical Study of Stressed Polyethylene and Butadiene Rubber Chain Scission
Russian Journal of Physical Chemistry B - Tập 12 - Trang 300-307 - 2018
B. E. Krisyuk, E. A. Mamin, A. A. Popov
The thermal decomposition of polyethylene and butadiene rubber chains in the presence of a tensile force acting along the axis of the molecule was simulated. The reaction of an isolated chain was considered. The chain models were the octane and 2,6-octadiene molecules. A deformation was introduced in the problem by fixing nonequilibrium distances between the terminal carbon atoms. The reaction coo...... hiện toàn bộ
Convective burning of fine ammonium nitrate–aluminum mixtures in a closed volume bomb
Russian Journal of Physical Chemistry B - Tập 10 - Trang 42-54 - 2016
B. S. Ermolaev, V. G. Hudaverdiev, A. A. Belyaev, A. A. Sulimov, V. E. Khrapovskii
It is commonly assumed that the burning of ammonium nitrate–aluminum mixtures is much less prone to undergo a transition to explosion and detonation than similar mixtures based on ammonium perchlorate. However, this conclusion has been made for mixtures based on commercial-grade ammonium nitrate with large particles. In this study, the combustion of fine loose-packed mixtures of ammonium nitrate a...... hiện toàn bộ
Comparative Analysis of Thermal and Physico-Mechanical Properties of Polyethylene Compositions Containing Microcrystalline and Nanofibrillary Cellulose
Russian Journal of Physical Chemistry B - Tập 15 - Trang 716-723 - 2021
A. N. Perova, P. N. Brevnov, S. V. Usachev, E. V. Koverzanova, A. V. Khvatov, S. M. Lomakin
The thermal and physico-mechanical properties of polyethylene composites with additives of microcrystalline and nanofibrillar cellulose (MCC and NFC) are investigated. Based on the results of the performed thermogravimetric analysis, the main temperature characteristics of the thermal and thermooxidative destruction of the obtained compositions are determined. The composition of the pyrolysis prod...... hiện toàn bộ
