Magnetic Circular Dichroism Analysis of Crude Oil
Optical and magneto-optical properties of solutions of crude oil of different origin (i.e., taken from different fields) are studied in the visible and near-UV region of optical emission. Magnetic circular ...
New class of bicyclic compounds derived from thiobarbituric acid with representative compound 1,3-diethyl-7-hydroxy-5,5,7-trimethy1-2-thioxo-1,2,3,5,6,7-hexahydro-4H-pyrano[2,3-d]pyrimidin-4-one
The colorless crystals of 1,3-diethyl-7-hydroxy-5,5,7-trimethy1-2-thioxo-1,2,3,5,6,7-hexahydro-4H-pyrano[2,3-d]pyrimidin-4-one (I) have been crystallized from the solution containing 1,3-diethyl-2-thiobarbituric acid ...

The crystal and molecular structures of thallium(I) thiobarbiturate C4H3N2O2STl (C4H4N2O2S is 2-thiobarbituric acid, Н2ТВА) have been determined. Crystallographic data for Tl(НТВА) are a = 11.2414(7) Å, b = 3.8444(3) Å, с ...
Genetic Algorithm for Automated X-Ray Diffraction Full-Profile Analysis of Electrolyte Composition on Aluminium Smelters
Aluminium is produced by means of the electrolysis of alumina in molten fluoride salts . A certain proportion of the fluoride compounds continuously evaporates, and this negatively impacts on the optimal composition of the ...
