[quick news] on November 26, 2019, domestic waste will be recycled by category, and nano materials will also be recycled?

Domestic waste should be recycled by classification, and nanomaterials should also be recycled? Yu Shuhong research group of University of science and technology of China successfully recovered the waste ions of tellurium and silver produced in the reaction of tellurium and silver nanocrystalline template to prepare multi-functional nanomaterials by designing reasonable chemical and physical recovery strategies, and prepared high-quality tellurium and silver nanowires by using them For all kinds of template reactions, most of the tellurium and silver elements have been recycled Through this process, the toxic element tellurium and precious metal element silver that were discarded at will in the past were recovered efficiently, which greatly reduced the cost of preparing multifunctional nanomaterials with this template and the harm to the environment The relevant scientific research results were published in the international journals chemistry-a European Journal (2015) and science of China: materials (2015) China materials, 2016) Https://new.qq.com/omn/20191125/20191125a02elh00.html the Chinese Academy of Sciences announced that the average age of the newly elected academicians in 2019 is 55.7 Recently, the website of the Chinese Academy of Sciences released the announcement of the newly elected academicians of the Chinese Academy of Sciences in 2019, announcing the newly elected 64 academicians of the Chinese Academy of Sciences and 20 foreign Academicians of the Chinese Academy of Sciences It is understood that in 2019, the work of academician's additional election of Chinese Academy of Sciences was officially launched on January 1, 2019 After the procedures of recommendation, communication review, publicity, meeting review and final voting of all academicians, a total of 64 academicians of Chinese Academy of Sciences were produced Among the newly elected academicians, there are 6 women; the average age is 55.7 years old, the minimum age is 42 years old, the maximum age is 67 years old, and 87.5% are under 60 years old Among them, there are 11 in the Department of mathematical physics, 10 in the Department of chemistry, 10 in the Department of life science and medicine, 11 in the Department of Geosciences, 7 in the Department of information technology science and 15 in the Department of technology science Https://tech.gmw.cn/2019-11/22/content_.htm a new revolution in the field of two-dimensional materials: "the development of human beings in the past 4000 years, from the porcelain age to the Bronze Age to the iron age, each era has a representative material We now live in the era of plastic and silicon, which is also the representative material of today's human civilization What's the next step? " In the recent 2019 China science fiction conference "technology and future" special forum, Nobel, 2010 physics prize winner, University of Manchester physics professor Andre Haim asked And his own answer is: two-dimensional materials Zhu Yanwu, a professor at the school of chemistry and materials science, University of science and technology of China, believes that finding a breakthrough in the application of two-dimensional materials from some directions or angles will probably stimulate or encourage the further development of the research field of two-dimensional materials Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-11 / 25 / content_ HTM? Div = - 1 scientists use computer programs to discover more than one million kinds of genetic molecules using computer programs International scientists began to look for whether there are still analogues of DNA and RNA As a result, they found at least 116 Ten thousand kinds of molecules that may store genetic information can help explain the evolution of life and search for life forms beyond the earth The related research report was published in the recent journal of chemical information and modeling A new study by researchers from the Tokyo Institute of technology, the German Aerospace Center and the University of Emory shows that more than one million chemicals with similar structures can encode biological information like DNA Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-11/25/content_.htm? Div = - 1 marine bacteria bring hope for the development of new antibiotics The international team led by the University of Jena in Germany has successfully cultivated dozens of hitherto neglected marine bacteria in the laboratory Preliminary bioinformatics analysis and cell biology observation show that new antibiotics may be produced The research has been published in the journal Nature microbiology Some bioinformatics analysis has been confirmed by researchers through experiments For example, they studied the cell biology of isolated planktonic bacteria "Their division is completely different from all the key pathogens," said Christian georgler, a microbiologist at the University of Jena This work also shows a new mechanism of bacterial cell division Most importantly, however, this study shows that even so-called "non culturable" bacteria can be obtained and identified in pure cultures http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-11/25/content_435456.htm?div=-1
