The aim of presented study was the detailed spectroscopic characterization of the mechanism of the photoreduction of hexachloroplatinate(IV) with methanol. The reaction mixture was illuminated at 375 nm and it was shown that PtCl62− ions were reduced with methanol to PtCl42− only in the presence...

Various types of pulsed fiber lasers operating beyond 1100 nm have been developed because of their important applications.

Published methods based on the use of water-soluble binary and ternary complexes for the spectrofluorimetric determination of terbium(III) are compared. The complexes formed by terbium(III) with (1) ethylenediamine-N,N′-bis-o-hydroxyphenylacetic acid, (2) o-hydroxyphenyliminodiacetic acid, (3) ...

The terbium ethylenediaminetetra-acetate anion forms a 1:1 mixed ligand complex with the trivalent anion derived from 5-sulphosalicyclic acid. Ultra-violet radiation absorbed by the organic portion of the mixed complex is efficiently converted to the green fluorescence characteristic of Tb3+. Qu...

The two forms of the hepatitis delta virus ribozyme are derived from the genomic and antigenomic RNA strands of the human hepatitis delta virus (HDV), where they serve a crucial role in pathogen replication by catalyzing site-specific self-cleavage reactions. The HDV ribozyme requires divalent m...
