Prof. Li Yan from Peking University research team to solve the problem of carbon nanotube application

Prof. Li Yan from the School of Chemistry and Molecular Engineering of Peking University has made important breakthroughs in the study of chiral controllable growth of single-walled carbon nanotubes. The results were published in the journal Nature. This study provides a possible solution to the problematic controllable growth of single-walled carbon nanotubes, which has laid a foundation for the application of carbon nanotubes, especially carbon-based electronics.

It is predicted that the microelectronics technology based on silicon-based CMOS integrated circuits will approach the limit of development in the next decade or so, and the development of nanoelectronic technology in the post-Moore era is imminent. In 2009, the International Semiconductor Roadmap Committee recommended carbon-based electronics based on carbon nanotubes and graphene as a next-generation electronic technology that could show commercial value in the next 10 to 15 years. Materials are the basis and key to the development of carbon-based electronics. However, there is still no way to achieve controllable growth of carbon nanotubes, which has become a bottleneck restricting the development of carbon-based electronics.

After 12 years of research, Prof. Li Yan gradually deepened the understanding of the growth mechanism and catalyst function of carbon nanotubes. On this basis, he proposed a structure/chiral controllable growth of single-walled carbon nanotubes. Program. They developed a class of tungsten-based alloy catalysts whose high melting point properties ensure that single-walled carbon nanotubes maintain a crystalline structure during growth in high temperature environments, and their unique atomic arrangement can be used to regulate the growth of carbon nanotubes. The structure thus achieves structural/chiral controlled growth of single-walled carbon nanotubes.

It is understood that the above research work was completed under the support of the National Natural Science Foundation of China Outstanding Youth Fund and the Major Research Project of the Ministry of Science and Technology, and was assisted by the Hong Kong Polytechnic University, the Institute of Physics of the Chinese Academy of Sciences, and the Shanghai Synchrotron Radiation Source.

Yoga mats and exercise mats are a hot topic right now â€“ how else are you going to smash those self-isolation home workouts?
From protecting your joints from injury on hard surfaces mid workout to keeping you steady and stable during yoga asanas and providing a softer surface to lower down to during chest-to         floor burpees (vom), a gym mat is the bread and butter of a great exercise kit. Now that we're all spending much more time 'en casa' there's never been a better time to invest.
