ELECTRIC FIELD EFFECT ON OPTICAL DICHROISM OF SOME AZODYES DISSOLVED IN COMPENSATED CHOLESTERIC LIQUID CRYSTAL
In the paper are presented the results obtained in the study of the optical dichroism of some azodyes dissolved in a compensated mixture of cholesteryl chloride and cholesteryl-nonanoate under the electric field action....
EFFECTS OF pH VALUE ON THE ELECTRODEPOSITION OF Cu4SnS4 THIN FILMS
Copper tin sulfide thin films were electrodeposited on the indium tin oxide substrates in a bath containing CuSO4, SnCl2 and Na2S2O3 solutions. Various pH values ranging from 1.1 to 1.5 were attempted in order to determi...
A CHEMICAL AND PHOTOCHEMICAL STUDY OF RADICALIC SPECIES FORMED IN METHYLENE BLUE ACIDIC AND BASIC AQUEOUS SOLUTIONS
Electron spin resonance spectra have been used to gain information on the mechanism of photolysis of aqueous solution of methylene blue. The identity and behaviour of the semiquinone radicals formed as intermediate reduc...
DINITROGEN ACTIVATION BY DIRUTHENIUM COFACIAL DIPORPHYRIN COMPLEX. DFT STUDY
Density functional theory and ab initio calculations are used to study the activation of dinitrogen by diruthenium cofacial diporphyrin complex [Ru2DPB(Im)2] (DPB= diporphyrinato-biphenylene tetraanion and Im= imidazole)...
CHEMICAL CONSTITUENTS FROM DENDROPHTHOE FALCATE
The ethyl acetate extract of the roots and leaves of Dendrophthoe falcate yielded apigenin-8-C-β-D (2"-O-β-D-glucopyranosyl)-glucopyranoside. The isolated compounds were characterized by U V, I R, N M R and mass spectral...
