Chemical physics, chemical kinetics, chain reactions, combustion and explosion processes, cool flames. Detection of free radicals in hydrocarbon oxidation degenerate branched chain reactions and the establishment of the mechanism of these reactions. It is shown that rarefied flames of hydrogen-oxygen mixtures under certain conditions can pass into a new, previously unknown mode – "intermittent flames". A new scientific direction was founded - the transformation of solid-phase and gas-phase inorganic compounds and materials under the effect of chain gas-phase reactions, which is also of practical and environmental importance
