    Experimental investigation of regularities of carryover of water mist droplets (radius of 50 - 500 [mu]m) by high temperature (500 - 1800 K) products of combustion of typical petroleum products (oil, gasoline, kerosene, etc.) was carried out. The panoramic optical methods and high-speed hardware and software systems were used. Speeds of droplets after mixing with oncoming high temperature gases were determined. Conditions of continuation of droplets movement through combustion products with preservation of initial trajectory in spite of intensive evaporation and braking were found. The predictive evaluation of effectiveness of water mist use for extinguishing of fires involving oil and typical petroleum products

The purpose of this work is obtaining of surface-modified gold nanoparticles and checking of their antimicrobial activity. During the study the synthesis and surface modification of gold nanoparticles with star-shaped form by arenediazonium tosylates was carried out. Antimicrobial activity was assessed for the unmodified and functionalized nanoparticles with and without infrared radiation
