我科学家已能直接观察到分子内部结构的真情。记者1月18日从中国科学技术大学了解到,这所学校研究人员成功获得直接观察分子内部结构的“眼睛”并在国际上首次直接拍摄到能够分辨化学键的单分子图像。这项具有先进水平的技术,为通过“切割”“组装”单分子化学键,进而达到“生产”人类所需的新分子、新材料奠定了基础。研究中,中国科学技术大学科学家们利用扫描隧道显微镜,将茏状结构的碳60分子组装在一单层分子膜的表面,在零下268℃时冻结碳60分子的热振,首先”拍摄”到能够清楚分辨碳原子同单键和双键的分子图像。利用该材料的优点,可能使计算机器
My scientists have been able to directly observe the truth of the internal structure of the molecule. The reporter learned from the China University of Science and Technology on January 18 that this school researcher has successfully obtained the “eyes” of directly observing the internal structure of the molecule and, for the first time in the world, has taken a direct shot of a single molecule image capable of distinguishing chemical bonds. This state-of-the-art technology paves the way for “cutting” and “assembling” single-molecule chemical bonds to achieve new molecules and new materials needed to “produce” humankind. In the study, scientists at University of Science and Technology of China (CAST) used scanning tunneling microscopy to assemble carbon nanostructures in a monolayer on the surface of a monolayer film. The thermal shock of 60 carbon molecules was frozen at -280 ° C Can clearly distinguish the carbon atoms with single and double bond molecular images. The advantages of using this material may make computing machines
