The mobility of fluoride and ammonium ions (180–480 K) in compounds K2? n (NH4)nZrF6 (0.2 ≤ n ≤ 1.70) was investigated by 19F and 1H NMR. Correlations have been found between the composition of the cation sublattice, the character of ion motions, and phase transition temperature in these compounds. The hightemperature modifications with n ≥ 0.85 of the compounds are characterized by translational diffusion of fluoride and ammonium ions and by uniaxial anisotropy of the 19F magnetic shielding tensor. The electrophysical characteristics of these compounds were studied in the temperature range 300–480 K. 相似文献

A method is described for isolating phosphatidylinositol (PI) from a lipid extract of soybean phosphatides. The method includes the separation of the extract with the aid of a Büchner funnel and alumina into two fractions — choline-containing phospholipids and a PI fraction — and the purification of the latter on a column of DEAE-cellulose. As a by-product, phosphatidylethanolamine with a chromatographic purity of 95–96% is obtained from the PI fraction.Institute of Marine Biology, Far Eastern Scientific Center, Academy of the Sciences of the USSR, Vladivostok.

Effect of electrochemically injected magnesium ions on the process in which carbonate deposits are formed on a corrodible surface of low-carbon steel in water of heat-and-water supply systems was studied. It was found that the anticorrosion efficiency of the deposit, evaluated by the polarization-resistance method and voltammetry, is approximately 1.5 times that of natural deposits formed in the absence of injected magnesium ions. X-ray diffraction analysis with grazing beam incidence, scanning electron microscopy, and energy-dispersive analysis demonstrated that mostly dense polycrystalline calcium carbonate deposits with a structure of aragonite are formed in the presence of magnesium ions. The mechanism by which a protective CaCO3 layer grows on the corrodible surface of low-carbon steel is discussed. 相似文献

The reaction of [Cd2{S2CN(CH2)6}4] (I) with morpholine gives a crystalline adduct of cadmium N,N-cyclo-hexamethylenedithiocarbamate [Cd{NH(CH2)4O}2{S2CN(CH2)6}2] (II), whose coordination sphere includes two molecules of the donor base. The structural organization and thermal behavior of II is studied by X-ray diffraction analysis and simultaneous thermal analysis in comparison with the original binuclear cadmium complex I. The central cadmium atom (coordination number 6) coordinates two morpholine molecules and two structurally equivalent S,S’-anisobidentate ligands HmDtc to form a chromophore [CdN2S4] with the structure of a distorted octahedron. The thermal destruction of II proceeds in two stages and includes consecutive steps of dissociation of the Cd-N bonds followed by the desorption of morpholine and thermolysis of the dithiocarbamate moiety of the adduct to form CdS as the final product. The structure of binuclear [Cd2{S2CN(CH2)6}4] is refined for a correct refinement of the geometric characteristics of compounds I and II. 相似文献

Evolution equations for marginal generalized microscopic phase densities are introduced. The evolution equations for average
values of microscopic phase densities are derived and a solution of the initial-value problem for the hydrodynamic type hierarchy
obtained is constructed. 相似文献
