国家纳米科学中心研究员裘晓辉团队,利用原子力显微镜技术实现了对分子间局域作用的直接成像,在国际上首次直接观察到了分子间的氢键。相关论文刊登在近日出版的《科学》杂志上。氢键是自然界中最重要、存在最广泛的分子间相互作用形式之一。虽然氢键的强度相对于共价键非常弱,但对物质性质有至关重要的影响。近年来,裘晓辉团队对现有仪器设备不断优化改造,自制原子力显微镜的核
Qiu Xiaohui, a researcher at the National Nanoscience and Biotechnology Research Center, has used atomic force microscopy to directly image the local effects of molecules and directly observed the intermolecular hydrogen bonding in the world for the first time. Related papers published in the recently published “Science” magazine. Hydrogen bonding is one of the most important and extensive forms of intermolecular interactions in nature. Although the strength of hydrogen bonds relative to the covalent bond is very weak, but the material properties are crucially affected. In recent years, Qiu Xiaohui team continuously optimize the existing equipment and transformation, self-made nuclear atomic force microscope
