It is found that existing metal ions and alcohols play key roles in the surface oxidation passivation of aminophosphine-based InP NCs, which significantly improve their photoluminescence (PL) photo-stability.

Lipid peroxidation (LPO) is an oxidative deterioration when oxidants such as reactive oxygen species attack lipids that contain double bonds especially polyunsaturated fatty acids (PUFAs). The mechanism of LPO composed three steps: initiation, propagation, and termination. It can result from several reaction pathways: (1) auto-oxidation, (2) enzymatic oxidation, or (3) photo-oxidation. UV solar...

Three substituted zinc (II) phthalocyanines (one anionic, one cationic and one hydrophobic) have been compared to two clinically used photosensitisers, 5,10,15,20-tetra (m-hydroxyphenyl) chlorin (mTHPC) and polyhaematoporphyrin (PHP), as potential agents for photodynamic therapy (PDT). Oxygen-consumption experiments, performed to follow the photo-oxidation of tryptophan, histidine and bovine se...

The oxidation of aqueous solutions carbamazepine is conducted using the Fenton reagent, combined with photolytic action a 150 W medium pressure UV lamp, operating at T = 40 °C. effect acidity analysed an interval pH 2.0–5.0, verifying that 5.0 promotes colour formation (Colour 0.15 AU). iron studied, finding water increases in linear way, Colour 0.05 + 0.0075 [Fe]0. oxidising hydrogen peroxide ...

Polyethersulfone (PES) films are widely employed in the construction of membranes where there is a desire to make surface more hydrophilic. Therefore, UV photo-oxidation was studied order oxidize PES and increase hydrophilicity. using low pressure mercury lamps emitting both 253.7 184.9 nm radiation were compared with only photons. The modified surfaces characterized X-ray photoelectron spectro...
