an investigation was conducted on hemin modified with axial ligand loaded onto magnetic carriers which created a kind of visible-light activated photocatalyst with good magnetic property. this photocatalyst exhibits excellent photo-degradation performance and can be readily reclaimed in the degradation of bis-phenol a (bpa) in aqueous solution under visible light. the catalysts were characteriz...

in the present study, theoretical chemical reactivates photo isomerization in cis-retinal as a natural photo switch in vision. dft hybrid functional, b3lyp and, post-hf method, were the theoretical methods applied utilizing g09 software. 6-31g+ (d,p) basis set employed for structural optimizations, and single point computations performed using b3lyp/6-31g+(d,p). the isomers cis molecule retinal...

High-efficiency and low-loss processing is the mainstay to reduce cost deepen application of 4H silicon carbide (4H-SiC) wafers in high-power high-frequency electronics. In this study, high-yield slicing 4H-SiC realized by combining femtosecond laser irradiation bandgap-selective photo-electrochemical (PEC) exfoliation. By light-absorption measurements, micro-Raman, micro-photoluminescence char...

Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems....

Palladium-metalated PCN-222 enables the aerobic photo-oxidative cross-condensation of anilines with benzylic amines yielding a series linear and cyclic imines. The reaction is very efficient under mild conditions, which allows isolation simple, yet elusive, intermediates such as 2-(benzylideneamino)aniline 2-(benzylideneamino)phenols. Recyclability studies show excellent activity selectivity af...
