In order to overcome the photocatalytic degradation reaction with a need for light excitation, the exploration of a catalyst for the organic degradation reaction without light has become one of the core challenges in catalysis and pollution control. Here we report a novel CuNiSeS nanosheet catalyst with a hexagonal structure by a feasible preparation method. The structure and composition of CuNiSeS were well characterized by X-ray diffractometry and electron microscopy, and X-ray pho- [a]
Abstract.Copper o xide and sulfide nanoparticles after annealing treatment at 400 ᵒChave been characterized and tested for their bactericidal properties toward Staphylococcus aureus and Escherichia coli under the dark and LED light illu minated conditions. It was found that the nanoparticles with the format ion of CuS/ Cu 2 S/CuO nanoheterostructuresexhib ited a great capability of killing Staphylococcus aureus and Escherichia coli with or without light illu mination. The antibacterial activity of the nanoparticles was demonstrated and simp ly observed with colony counting method. A mechanism of the antibacterial behaviour had been proposed and elucidated in this work.
The contamination effects induced by B2H6 and B(CH3)3 in a-Si:H layers are compared, using in-situ Kelvin probe experiments as well as SIMS measurements. It is found that B(CH3)3 induces at least 50 times less contamination, even at 250°C. It is also found that materials containing CH3 radicals have a lower electron affinity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
