Development of super elastic and fatigue resistant carbon nanofiber aerogels The research team of academician Yu Shuhong and Professor Liang Haiwei combined with Professor Liang Haiwei By pyrolysis chemical control, the structural biomaterials were transformed into graphite carbon nanofibers aerogels, which perfectly inherited the macroscopic and microscopic structure of bacterial cellulose, with significant thermal mechanical properties and large-scale synthesis Because carbon nanofiber aerogels have excellent thermal stability mechanical properties and can achieve macro fabrication, they will have important application prospects in many fields, especially for mechanical buffering, pressure sensing, energy damping and aerospace solar cells under extreme conditions Http://digitalpaper.stdaily.com/http_ / 24 / content_ HTM? Div = - 1 our scientists reveal the unique quantum interference effect of charge transport in perovskite materials Li Yuelong, associate professor of School of electronic information and optical engineering, Nankai University, cooperated with Professor Hong Wenjing, School of chemistry and chemical engineering, Xiamen University, and academician Colin Lambert, University of Lancaster, UK, to report the unique quantum interference effect of perovskite materials in nanoscale charge transport for the first time in the world, which provides the possibility for the preparation of perovskite materials and devices based on quantum effect 。 This important breakthrough in interdisciplinary international cooperation has successfully expanded the quantum interference research system to the field of perovskite materials, which is expected to uncover the secrets behind high-efficiency perovskite solar cells and other photoelectric devices, and open up a new research field of new high-performance perovskite optoelectronic devices based on quantum effects Http://digitalpaper.stdaily.com/http_ / 24 / content_ HTM?

Recently, sun Jiashu research group of national nano science center of Chinese Academy of Sciences has made progress in microfluidic precise assembly and racemic chiral measurement Compared with the conventional detection method, this method does not need to use other chiral molecules, avoids the complex pretreatment steps such as derivatization and chiral separation, and provides a new idea and tool for the measurement of chiral molecules http://news.bioon.com/article/6748350.html
