Recently, with the support of the Beijing Municipal Science and Technology Commission, the team of academician Li Yadong of Tsinghua University successfully prepared monoatomic nanometer rhodium tablets for the first time in the world. The relevant results were published in the international authoritative academic journal Nature-Communication. Since the discovery of graphene, scientific research on single-layer materials containing delocalized large P bonds has focused on material systems with layered structures. Due to the non-directionality of metal bonds, it is easy to form a three-dimensional close-packed structure, so far the metal structure of a monoatomic layer with delocalized electronic properties has not been reported. The team of academician Li Yadong of Tsinghua University used the weak ligand polyvinylpyrrolidone (PVP) stabilized formaldehyde to reduce rhodium metal, and successfully prepared the world's first monoatomic layer thickness nano-metal rhodium sheet. This novel monoatomic metal structure. Theoretical research found that there is a new type of delocalized large chemical bond in the monoatomic layer rhodium sheet, which helps to stabilize its monolayer metal structure. The research progress is of great significance to further promote the research of chemical bonding theory of metal nanometers and clusters, and enrich the development of heavy metal elements, and provides important inspiration for the exploration of the structure and performance of metal atom monolayers. In recent years, the Beijing Municipal Science and Technology Commission has taken the initiative in innovation breakthroughs and industrial gathering as the starting point. It has spearheaded the launch of the "Beijing Nanotechnology Industry Leap-up Project", actively exploring the mode of mass transformation of nanotechnology achievements, and cooperating with the Huairou District Government to build Beijing Nanotechnology Industry The park has achieved fruitful results. More than 40 innovative technologies of academicians with international leading level, such as super-aligned carbon nanotube arrays, nano-generators, nano-imprinting, nano-green plate-making, and carbon-based integrated circuits, have landed in Beijing; attracted and gathered foreign academicians Wang Zhonglin of the Chinese Academy of Sciences and the American Academy of Engineering Academician Zhou Yu, academician Fan Shoushan and others from Tsinghua University and other top talents in the field of nanotechnology have initially built a high-tech nanotechnology innovation area; Beijing Nanotechnology Industrial Park has been recognized as a national nanotechnology industrialization base and has signed 30 industrialization projects; Nano professional incubator and strategic cooperation with nano parks to achieve the orderly achievement of nano science and technology achievements, through the "science and technology + achievements + park" model, explore an effective batch of nano science and technology achievements into the "Beijing model".
