In the given article results of studies on experimental estimate of possibility of waste recycling of production of TNT in foam glass are presented. Authors for the first time demonstrated experimentally that there is a real possibility of using wastes as a feedstock to produce silicate foam glass, which in turn is used for the manufacture of silicate glass foam - one of the most effective and eco- friendly modern heat-insulating materials. Initial raw charge used for producing silicate glass comprises a third waste, which significantly reduces the cost of resulting foam glass. For purification of gaseous discharges formed from the manufacture of original silicate glass from nitrogen oxides, an efficient thermal method for neutralizing them on the basis of active carbons is first suggested. It is shown by experiments that the highest possible degree of cleaning (≈ 98 %) in the present process can be achieved at 580-600 ◦C.

The new technological process of generation of nitrobenzene is presented in this article. The possibility of using the sugeested technology in industry instead of using sulfuric-nitric acid mixtures is shown.

В статье дается предварительная теоретическая оценка возможности применения нового способа наблюдения метеоров в атмосфере Земли с помощью искусственных светящихся облаков. При попадании метеоров в такие облака, образованные веществом с потенциалом ионизации в несколько раз меньшем потенциала ионизации атмосферных газов, происходит быстрая ионизация реагента облака за счет термического и ударного воздействия метеорного тела, приводящая к увеличению светимости метеорных следов. Предполагается, что такой эффект будет способствовать увеличению яркости слабых метеоров, находящихся на пороге обнаружения современных телевизионных камер. Это позволит проводить исследования метеоров и метеорных потоков, доступных ранее только радиолокационными методами наблюдения. The article provides a preliminary theoretical assessment of the possibility of using a new method of observing meteors in the Earth’s atmosphere using artificial luminous clouds. When meteors hit such clouds formed by a substance with an ionization potential several times lower than the ionization potential of atmospheric gases, the cloud reagent is rapidly ionized due to the thermal and impact effects of the meteor body, which leads to an increase in the luminosity of meteor tracks. It is assumed that this effect will increase the brightness of weak meteors, which are on the threshold of detection by modern TV cameras. This will make it possible to conduct studies of meteors and meteor showers that were previously available only by radar observation methods.

The results of longstanding investigation of developing and natural testing of devices for the spherical clouds creation from vaporized alkaline and alkaline earth metals azides in the upper earth atmosphere are given in the following article.
