HYDROGENATION ACTIVITY OF ADSORBINGRESIN SUPPORTED PALLADIUM-METALLIC OXIDE CATALYSTS张胜民,胡卫兵,周忠信,张曼征摘 要:<正>Hydrogenations for olefinic double... from Fe atom in Fe2O3 to Pd, enhanced the hy-drogenation activity of the catalysts, and Bi2O3 drew electronsfrom Pd, leading to the lowering of the hydrogenation rate.When Pd/Bi atom ratio=1......
J. Cent. South Univ. (2021) 28: 2463-2471 DOI: https://doi.org/10.1007/s11771-021-4739-1 Periodic electromagnetic signals as potential precursor for seismic activity YONG Shan-shan(雍珊珊)1, WANG Xin...-Verlag GmbH Germany, part of Springer Nature 2021 Abstract: Electromagnetic signals may be a promising precursor to seismic activity which has been observed in many case studies in past decades. However......
antibacterial activity of flower-shaped℃uO nanostructures were tested against gram-positive(Bacillus subtilis,Bacillus thuringiensis) and gram-negative(Salmonella paratyphi,Salmonella paratyphi-a,Salmonella paratyphi-b,Escherichia coli and Pseudomonas aeruginosa) bacteria.Also,the antifungal activity of℃uO was investigated against Aspergillus niger,Rhizopus oryzae,Aspergillus flavus,Cladosporium carrionii......
