A method of atomic resonance absorption spectroscopy has been developed to study the kinetics of mono- and bi-molecular reactions in a wide range of temperatures and pressures.
The kinetics of monomolecular decomposition of iodine inhibitors was studied experimentally and numerically.
The kinetics of high-temperature oxidation of promising biofuels (methane, butanol, dimethyl ether, ethanol, n-/iso-propanol) with molecular and atomic oxygen was studied.
Non-equilibrium emission of carbon monoxide during high-temperature oxidation of biofuels was discovered and studied, a kinetic mechanism was proposed that allows taking into account excited CO molecules during combustion
Ways and methods for improving modern combustion mechanisms have been determined, recommendations have been developed to reduce the overall uncertainty of combustion kinetic schemes
