The application of microencapsulated liquid gasifiable fire extinguishing agents as reactive filling compounds for fire extinguishing composites is considered. A new process for microencapsulation of envi ronmentally friendly fire extinguishing agents possessing enhanced stability is designed. Novel composite materials are produced with these agents. The thermal destruction processes of microcapsules containing liquid gasifiable fire extinguishing agents of different compositions are considered. Laboratory and bench mark firing tests of the materials are performed.
The results of theoretical studies and numerical simulations of laser-driven acceleration of a flat foil up to ultrahigh velocity of the order of 1000 km s −1 , which corresponds to the achievement of thermonuclear temperatures due to kinetic energy transition into thermal energy at an inelastic impact, are reported. The behavior of a foil accelerated to such high velocities, in particular, the distribution of foil density, which defines thermonuclear reaction intensity, has been studied. The calculation results are compared with the results of the experiments performed on the Gekko/HIPER laser, where a laserdriven projectile achieved record-breaking velocity. The laser pulse and foil parameters responsible for acceleration of the projectile up to 'thermonuclear' velocities in a dense state have been determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
