AbstractIn this paper, we study the effect of a heterogeneous autocatalytic reaction on the quartz reactor surface occurring after ignition in an H2/O2 medium near the third limit on the initiation of an explosion of a hydrogen–oxygen mixture in a cold volume of lines adjacent to the reactor. Under certain conditions, a second flash occurs in most ...

AbstractThe phenomenon of thermophoresis in a gas discharge in neon is studied in the presence of structures of charged dust particles. This system can simulate gas with combustion products in the form of a condensed dispersed phase. The relationship of the thermophoresis force acting on charged dust particles in a plasma with their concentration a...

AbstractThe results of an experimental study of shock wave (SW) attenuation in mixtures of magnesium and aluminum with solid metal oxides upon contact blasting of explosive charges are presented. Faster attenuation is found in reactive mixtures compared to homogeneous materials of similar compressibility and inert mixtures, which is related to the ...

AbstractThe paper presents the results of studies of coatings formed by gold, copper, nickel, and palladium nanoparticles in various combinations on the surface of highly oriented pyrolytic graphite. It was shown that the structure of the bimetallic coatings and the adsorption of hydrogen, oxygen, and carbon monoxide on them are affected by interac...

AbstractThe article assesses the impact of the main significant external factors in determining the TNT equivalency of air explosions. The effects of errors in measuring the distance to the epicenter and pressure on the front of the air shock wave (ASW) on the TNT equivalency value calculated by the Sadowski empirical is considered. The errors in d...

AbstractThe antiradical properties and biological activity of natural polyphenol—resveratrol—are studied. The chemiluminescence method recorded high values of the antiradical activity of this drug. Using the model system, it is shown that the drug in the concentration range of 10–5 to 10–12 M prevented the activation of lipid peroxidation (LPO) in ...

AbstractIn this paper, we perform a numerical analysis of the parameters of shock waves (SWs) generated during the expansion of cylindrical volumes of compressed methane. A single dimensionless approximation of the overpressure dependence on the distance is obtained using precise numerical solutions. The overpressure values in the SW are estimate...

AbstractThe model composition of municipal solid waste (MSW) and its ash chemical composition are characterized. Mineral compounds and melting points are studied using a variety of analytical methods, including XRD, FTIR, and AFT. The main parameters of slag formation are calculated: base-to-acid ratio, slag viscosity index, and fouling coefficient...

AbstractThe gasification of used tires in the filtration combustion mode is studied using calcium-containing additives, both chemically inert and those capable of absorbing sulfur. It is found that during the gasification of compositions with an inert additive, 28, 29, and 43% of the sulfur contained in the initial material passes into the ash, res...

AbstractThe thixotropic properties of aqueous solutions of the following polysaccharides are studied: chitosan, its water-soluble derivative the sodium salt of chitosan succinamide, and the sodium salt of carboxymethyl cellulose. These polymers have been selected due to their physiological activity and the possibility of using them for biomedical p...
