Isothermal nucleation of gas hydrates in two-layer water–organic liquid systems was studied with the use of Sapphire Rocking Cell RCS6 with six transparent sapphire cells by thermal analysis under gas pressure. The experiments were conducted at constant supercooling (about 20.2 °C). Decane (both with and without surfactants Surfynol 420 and Span 80) and crude oils were used as organic liquids. It...
Structure and the nonlinear optical (NLO) susceptibility are tabulated for 110 noncentresymmetric (NCS) crystals of the simple and binary carbonates, tartrates, formates, oxalates, acetates, and fluoride-carbonates, using in optoelectronics. It is shown that in the plane of the metal-oxide bond lengths these crystals are positioned inside of the vertical, horizontal and slope intersected ellipses...
Structure and the nonlinear optical susceptibility are tabulated for 220 acentric crystals of simple and binary borates, using in optoelectronics. It is shown that in the plane of the metal-oxide bond lengths these crystals are positioned inside of the vertical, horizontal and slope intersected ellipses of «acentricity». The crystals with moderate susceptibility are found into central parts of these...
In the present paper, we consider the influence of magnetic fields B ≤ 2 T on the electric current in thin PbSnTe:In films, kept at Т=4.2 K, with prevailing injection of charge carriers out of contacts and space-charge-controlled limitation of the current. Data for various orientations of the field B with respect to the direction of the current in the film plane, and also data on transient currents,...
