To efficiently remove perfluorooctanoic acid(PFOA),we developed a composite of magnetic Fe_(3)O_(4)nanocrystals and MIL-101(an iron-based metal organic framework).Because of its high surface area,porous structure,and ...
In 1984,a bronze yon was unearthed at the Yinxu site in Henan Province,discovered by a young archaeologist during an excavation.The yon was a cooking vessel from the Shang Dynasty,consisting of two parts:The upper par...
Recently,people have been discussing a heated topic:the gap between China’s gross domestic product(GDP)and that of the United States is getting bigger and bigger.According to statistics from the International Monetar...
