Weigh! In 2019, the National Excellent Youth list was officially published, and 625 items were funded from NSFC In 2019, the National Excellent Youth list was officially published According to the final list, 625 NSFC programs were funded in 2019, 225 more than last year, and 25 more than the list released in August this year On August 16, the National Natural Science Foundation of China announced that it decided to fund 600 NSFC programs for outstanding young scientists this year, an increase of 200 over last year 25 items have been added to the final list, and the supporting units are from Hong Kong and Macao Http://news.scienceet.cn/htmlnews/2019/11/432543.shtm Chinese scientists have developed new nano luminescent materials to help photodynamic therapy of tumor The research group of rainfall intensity obtained by Institute of genetics and developmental biology of Chinese Academy of Sciences and the research group of Sha Yinlin of Peking University School of basic medicine have jointly organized a team to recently develop a new nano luminescent material - gold nano cluster with dihydrolipoic acid as ligand, which can provide assistance for photodynamic therapy of tumor It is found that the gold nanoclusters with dihydrolipoic acid as ligand have strong free radical production characteristics under light, and have very good killing effect on tumor cells and tissues They are excellent photosensitizers for photodynamic therapy, and their curative effect is far better than that of Eira photosensitizers in clinical use In addition, the material has excellent two-photon properties, can be excited by near-infrared laser, effectively increase the depth of irradiation, and can be used for solid tumor treatment More importantly, the material has good biocompatibility, and the treatment process does not need to avoid light, which greatly improves the clinical controllability This research achievement has applied for 2 invention patents, and has recently been published online by ACS Nano, the top international journal of nanotechnology Http://www.chinanews.com/cj/2019/11-12/9005468.shtml has played a role in the treatment of epilepsy Recently, Liu Si, a young teacher from school of life sciences, Tianjin University, and his collaborators first analyzed the high-resolution structure of human potassium chloride cotransporter protein (kcc1), and proposed potassium- The mechanism of chloride co transport provides a new perspective for the treatment and drug design of epilepsy and other related diseases As the first author, Liu Si published relevant papers in the top academic journal Science Based on the single particle frozen electron microscope technology, Liu Si and the research group successfully analyzed the atomic resolution structure of kcc1 from three human sources, found that kcc1 existed in the form of dimer, explained the mechanism of simultaneous and simultaneous transport of potassium and chloride ions in the proportion of 1:1, and proposed the model of kcc1 co transport of potassium and chloride ions The results of this study have great practical significance and application value for the research and development of epilepsy treatment drugs targeting on cation chloride cotransporter Http://news.scienceet.cn/htmlnews/2019/11/432585.shtm chlorine free bleaching is a kind of "detoxification" and "whitening" technology for pulp, which is jointly developed by the State Key Laboratory of bio based materials and green paper industry of Qilu University of technology and the Key Laboratory of pulp and paper science and technology of the Ministry of education of pulp and paper science and technology The clean and efficient bleaching technology for fast-growing poplar chemical pulp has reached the international leading level through expert identification According to the person in charge of the key laboratory, the brightness of the pulp after bleaching with this new bleaching technology can be increased by 1.7% - 3% compared with that of the original chlorine free and chlorine free bleaching, and the biochemical capacity of the bleaching wastewater can be greatly improved, and the chemical oxygen demand content in the bleaching wastewater can be reduced by 15% The technology of quick-growing poplar chemical pulp prepared by enzyme softening and deep dredging can save 20% of energy consumption The physical properties of the fast-growing poplar chemical pulp are better than those of the same kind of products in the world Compared with the control pulp, the main strength index is increased by about 10%, and the whiteness is increased by more than 2% Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-11 / 13 / content_ HTM? Div = - 1 the king of new materials assists in the attack of Chinese core, reducing the delay by 1000 times, or effectively responding to the "neck sticking" Recently, the Institute of metals of the Chinese Academy of Sciences said that its researchers have prepared the first vertical structure transistor "Silicon" with the Schottky junction as the emission junction- Graphene germanium transistor ", a transistor based on graphene material, can shorten the delay time by more than 1000 times, and increase its cut-off frequency from terahertz to gigahertz This is also a new breakthrough of" China core ", which is of great significance for the development of related electronic materials in China https://www.toutiao.com/a6758380035263955463
