Effect of defects of the domain structure on the optical properties of ferroelectric crystals

The effect of irregularities of a periodic domain structure on the efficiency of the second harmonic generation has been numerically investigated in the case where the structure is formed by the high-voltage method. The irregularities associated with the uncontrollable motion of domain walls from under electrodes, as well as with the presence of internal defects in the crystal, have been analyzed.     

Effect of Pretreatment Conditions on the Catalytic Activity of Benzene Combustion Over SBA-15-Supported Copper Oxides

The effect of the pretreatment conditions on the catalytic combustion of benzene over copper oxides supported on SBA-15 was investigated. The catalytic activities of the reduced catalysts were higher than those of the unreduced catalysts, indicating that the metallic Cu is much more active than the copper oxides.     

Effect of mechanical activation on thermal explosion in Ni-Al mixtures

The effect of mechanical activation (MA) on thermal explosion in equimolar Ni-Al mixtures was studied by time-resolved XRD. MA was also found to increase the burning velocity and decrease the ignition temperature. Thermal explosion in non-activated Ni-Al mixtures was found to proceed via formation of liquid (melted) intermediate products, while that in the activated mixtures gave no liquid intermediates.     

Distribution of mineral components in the hydrothermal-processing products of sapropelite organic mass

The hydrothermal treatment of sapropelite is investigated, to establish the distribution of mineral components in the decomposition products. In hydrothermal pyrolysis, an organic-mineral mixture is obtained. The mineral components may be extracted from this mixture. The results suggest that the carboxylic acids obtained from hydrothermal treatment of sapropelite have valuable extractive properties. The characteristic reactions for the carboxylic acids are substitution reactions, with the formation of salts of various metals.     

Radioactivity of coal and ash

The radioactivity of Kuznetsk Basin coal and ash is considered, in relation to other regions.     

Coal mining in the Russian Donetsk Basin

The activities of coal companies in the Russian Donetsk Basin (Rostov oblast) are considered, as well as the basic coal characteristics, the potential value of local reserves, and the prospects for the region in current economic conditions.     

Reducing the phenol content in coal tar and in coke-plant water flows

The influence of coking-product pyrolysis within the coke furnace on the phenol content in coal tar and in the water in the gas-collection cycle and at the biochemical-treatment unit is considered.
