The quantum-chemical method is a crucial area of innovation for photodynamic therapy. Density Functional Theory can be used to investigate the electronic structures, excited states, and other photochemical properties of a photosensitizer. In the present study, the intensities and energies of electronic transitions are calculated, and absorption and...

One percent supported bimetallic catalysts based on palladium with silver, nickel or copper additives with the ratio of Pd: Me = 3: 1 have been developed. The active phase was stabilized with the polyethylene glycol (PEG-6000) adsorbed on the zinc oxide. The 1% Pd-Ag (3: 1)-PEG/ZnO catalyst, reduced with sodium borohydride has shown high activity,...

Treatment of wastewater by adsorption is one of the most environmentally friendly methods, along with high efficiency. The main criteria when choosing materials for wastewater treatment by adsorption are its adsorption properties, porous structure and cost-effectiveness. Heavy metal ions are the main pollutants present in wastewater from machine-bu...

Copolymerizations of unsaturated compounds with different ratios of acrylic monomers were synthesized. The synthesized copolymers exhibit good adhesion, flexibility and waterproofing performance may be used in the paint industry. The behavior of the copolymers of MMA and BuMA and proven by IR spectroscopy. This paper describes the synthesis, struct...

The effect of polymers on the formation of nanosized palladium catalysts for the selective hydrogenation of acetylenic alcohols to give alkenols was studied. Various physicochemical methods such as TEM and XPS were used to show that palladium nanoparticles with diameter 1-4 nm stabilized by polyethylene glycol or pectin on a ZnO support display enh...
