Academician Peng sixun, a famous pharmaceutical chemist and educator, senior academician of Chinese Academy of engineering, professor and doctoral supervisor of China Pharmaceutical University, died in Nanjing on December 9, 2018 at the age of 100 Academician Peng sixun was born in Baojing, Hunan Province in July 1919, Tujia nationality He entered the national pharmaceutical college in 1938 and graduated in 1942 He successively worked in the central health Experimental Institute and the drug and Food Inspection Bureau In 1948, he went to the University of Maryland and Columbia University to study In 1950, he received a master's degree in pharmacy from Columbia University, and applied for and was allowed to continue his doctoral studies After the Korean War broke out, he resolutely returned to his alma mater to teach and serve the motherland Since 1951, he has successively served as associate professor, Professor, director of teaching and Research Office, Dean of academic affairs and vice president of Nanjing Pharmaceutical College He was elected academician of Chinese Academy of Engineering in 1996 Academician Peng sixun has been engaged in the teaching and scientific research of pharmaceutical chemistry for a long time, advocating the idea of using the effective components of Chinese herbal medicine as the precursor to optimize the structure and create new drugs with independent intellectual property rights He led the research team for ten years to systematically study the cardiovascular activity of isoquinoline compounds and achieved remarkable results Http:// the new platinum catalyst reduces the cost of hydrogen fuel production, and hydrogen production costs are high and easy to oxidize in fuel cells, which are two major obstacles to the development of hydrogen energy At present, palladium, platinum and other precious metals are generally used as catalysts for hydrogen production Chemists from the University of the southern Federation of Russia have developed a new type of platinum catalyst, in which the platinum content is greatly reduced, but the efficiency is significantly improved Researchers have developed a new type of particle that allows platinum atoms to grow uniformly from the core to the surface of the nanostructure The first round of tests showed that the degradation rate of the nanoparticles was 7-8 times slower than that of the ordinary nanoparticles The catalyst can also be used to make other metals for fuel cells, which will accelerate hydrogen energy development and help the global economy embark on a path of sustainable development, the researchers said Http://sputniknews.cn/science/201812041027018885/kao develops microfiber, which can spray skin care directly ）Technology, that is, the diameter of submicron grade microfiber is directly sprayed on the skin, which can form a soft and natural layer type ultra-thin film on the skin surface, so as to achieve the purpose of skin care In the field of non-woven fabrics, the electrospinning method (ES method) is used in the microfiber technology This method is to spray the positively charged polymer solution on the surface of the negatively charged object, just like silk spinning for cocoon, the polymer solution is stretched into silk shape through the nozzle and sprayed out forcefully, overlapping layers on the surface of the object, forming a film This technology has a bright future in the field of skin care, cosmetics and other cosmetics, and will be applied in the medical field in the future Http://digitalpaper.stdaily.com/http_ / 11 / content_410194 HTM?
