The scattered rare metals( In,Ge and Ga) were comprehensively recovered from indium slag via a series of processes including acid leaching,the extraction of indium and gallium,and the precipitation of germanium. The opti...
The near infrared spectroscopy method was used to detect the methanol content in base liquor.The spectral data were processed and the quantitative analysis model of methanol was established by partial least squares.By op...
In order to prevent computer data from being stolen by the U disk and causing information leakage, a unidirectional high-speed reading U disk system based on optical fiber was proposed, which allowed the data to be accur...
The enantioselective arylation reaction of pyrazolones with quinone monoimines promoted by a chiral phosphoric acid was disclosed.The effects of catalyst, reaction solvent, and temperature on asymmetric arylation reactio...
