The determination of photostability for Mg-BChl a, Zn-BPheo a and Cu-BPheo a irradiated with red light (= 630 nm, 870 lux) and equilibrated with air for 20 min in acetone-water and methanol-water solvents at various percentages of water has been done. The... see more

The study of medicines stability is one of the fundamental issues in quality assurance system. In accordance with developed countries current legislation, the rules of Good Manufacturing Practice, one of the responsibilities of the manufacturer is study o... see more

The absorption and fluorescence spectra at different excitation wavelengths of the recently reported rhenium carbonyl complexes [Re2(µ:ï¨3-C12H10N2)(CO)8 (1), [Re2(µ-H)(µ:ï¨3-C12H9N2)(CO)7 (2) and [Re2(µ-H)(µ:ï¨5-C12H9N2)(CO)6 (3) have been studied and co... see more

A novel ultrathin g-C3N4 nanosheet-modified BiOCl hierarchical flower-like plate heterostructure (abbreviated as BC/CN) was constructed via a thermal polymerization of urea precursor followed with hydrolysis route. The as-prepared samples were well charac... see more

In the current endeavor, a new Schiff base of 14,15,34,35-tetrahydro-11H,31H-4,8-diaza-1,3(3,4)-ditriazola-2,6(1,4)-dibenzenacyclooctaphane-4,7-dien-15,35-dithione was synthesized. The new symmetrical Schiff base (Q) was employed as a ligand to produce ne... see more

Titanium dioxide (TiO2) has gained a lot of research interests due to its applicability in electronic materials, energy, environment, health & medicine, catalysis etc as a result of its high permittivity, refractive index, efficiency, low-cost chemica... see more

The dioxide titanium (TiO2) is attracting a great attention as semiconductor photocatalyst because of its high photoreactivity, non-toxicity, corrosion resistance, photostability, cheapness. It can be used in wide range of applications: air and water puri... see more

The degradation of propranolol hydrochloride (1-isopropylamino-3-(naphthoxy)-2-propranolol) in an aqueous solution was analyzed when irradiated by light UV, with and without ß-cyclodextrin. There was an increase in the compound´s photostability in nanocav... see more

The photocatalytic degradation efficiency of CoTiO3 coupled Sr, N codoped TiO2 has been examined by the degradation of Reactive Yellow 84 (RY 84) under solar light irradiation. The efficient CoTiO3/Sr, N codoped TiO2 based heterojunction composite was pre... see more
