Nonlinear Theory of Spectra of Thermally Stimulated Currents in Complex Crystals with Hydrogen Bonds
Tonkonogov M. P. Ismailov Zh. T. Timokhin V. M. Fazylov K. K. Kalitka V. A. Baimukhanov Z. K. 《Russian Physics Journal》2002,45(10):1008-1018
The nonlinear theory of thermally stimulated depolarization currents is developed. The theory explains the processes of hetero- and homocharge relaxation in complex crystals with hydrogen bonds and allows the relaxation oscillator parameters to be calculated using the quadratic approximation for the external electric field. 相似文献

Results of thermochemical studies of a new compound, potassium morpholinodithiocarbamate, are presented. The enthalpies of its solution in water at various dilutions and the specific heat at 173–348 K were examined by the experimental methods of isothermal and dynamic calorimetry. 相似文献

The results are given of the synthesis and a comparative study of the toxicities of some phosphorylated derivatives of the
alkaloids l-ephedrine and d-pseudoephedrine. It has been shown that the introduction of phosphorus- and sulfur-containing
fragments considerably lowers the toxicity of the alkaloids.

-(Thiocarbamoylthio)propionic acids derived from alkaloids, morpholine, and piperidine and their esters, amides, and nitriles were prepared by reactions of the corresponding dithiocarbamic acids with acrylic acid and its derivatives. Some of the compounds were tested for insecticidal activity.Translated from Zhurnal Prikladnoi Khimii, Vol. 77, No. 8, 2004, pp. 1336–1339.Original Russian Text Copyright © 2004 by Zhivotova, Gazaliev, Ibraev, Fazylov, Kasenov. 相似文献

The process of extracting ephedra herbage in a constant electric field has been studied. It has been shown that the application of an electric field considerably accelerates the isolation of the alkaloid molecules from the cellulose of the plant raw material. The main kinetic characteristics of the electroextraction of the total alkaloids as functions of various factors have been obtained.Institute of Organic Synthesis and Coal Chemistry, Kazakh SSR Academy of Sciences, Karaganda.

Heat of solution of salsoline salsolinodithiocarbamate (SS) at 1 : 18 000, 1 : 36 000, and 1 : 72 000 dilution (mol per mol H2O) was determined on a DAK-I-IA calorimeter, and the standard heat of solution at infinite dilution was estimated. The temperature dependence of the heat capacity of SS was studied over the range 173–348 K. The heats of combustion and fusion, and the standard heat of formation of liquid (molten) and crystalline SS were estimated by indirect methods. 相似文献

An immunochemical investigation has been made of the culture liquid after the cultivation of ten strains of the microorganisms Yersinia pseudotuberculosis. It has been shown that in the process of vital activity all the strains investigated, to a greater or smaller degree, produce into the culture medium products of catabolic breakdown consisting of fragments of receptor proteins which are possibly, regulators of metabolic processes taking place under the influence of the constantly changing conditions of the growth medium.Pacific Ocean Institute of Bioorganic Chemistry, Far Eastern Branch, Russian Academy of Sciences, Vladivostok.

The electrooxidation of the alkaloid ephedrine at solid electrodes in a wide range of concentrations and pH values of solutions
has been studied by the methods of potentiodynamic voltammetric curves, preparative electrolysis, and quantum-chemical calculations
by the SCF MO LCAO method in the MINDO/3 approximation. A quantitative basis has been given for the sequence of stages in
the electrooxidation of ephedrine proposed previously by the authors of one of the cited papers. Good agreement has been established
between the values found theoretically and experimentally.
