[quick news] on November 11, 2019, nature released five "scientific keywords" in the first decade of this century

Cell, quantum, DNA, protein and receptor are the most "hot" Nature published five "scientific keywords" in the first decade of this century British journal Nature published its 150th anniversary special issue on the 7th, with an exclusive analysis from 1900 From 2000 to now, the citation and references of tens of millions of scientific papers in thousands of research journals reveal the changes of scientific research in history It is found that in the first 10 years of this century, the most common keywords are "cell", "quantum", "DNA", "protein" and "receptor" The researchers also found that today's scientific papers cover and influence more subjects than at any time in history, which also highlights the continuous development of interdisciplinary thinking "With the growing number of researchers, research literature and knowledge, science has been converging across borders," said Barbara Buss, a network scientist at Northeastern University and colleagues Http://digitalpaper.stdaily.com/http_ Div = - 1 new bleaching technology to realize clean and efficient bleaching of fast-growing poplar chemical pulp The clean and efficient bleaching technology of fast-growing poplar chemical pulp, which is jointly developed by the State Key Laboratory of bio based materials and green papermaking of Qilu University of technology and the Key Laboratory of pulp and paper science and technology of the Ministry of education, has reached the international leading level through expert identification recently According to the person in charge of the key laboratory, the brightness of the bleached pulp can be increased by 1.7% - 3% compared with the original chlorine free and all chlorine free bleaching, and the biochemical capacity of the bleached wastewater is greatly improved, and the chemical oxygen demand content in the bleached wastewater is reduced by more than 15% The fast-growing poplar chemical pulp process prepared by the biological enzyme softening and deep dredging technology can save energy 20% 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:// Yinchuan Economic Development Zone promotes the development of new material industry in the whole industry chain as one of the "ten industries" Yinchuan economic development zone is accelerating its development engine, building a leading enterprise in the industry, improving the whole industry chain and rapidly forming a strong scale through "building chain, supplementing chain and strengthening chain" Graphene, monocrystalline silicon photovoltaic materials, industrial sapphire, large-scale integrated circuit silicon chips and a number of innovative enterprises with large market scale and strong technical ability gather and extend the industrial chain, forming the industrial agglomeration effect Relevant principals of Yinchuan Economic Development Zone said that through the implementation of "31555" enterprise cluster construction, the output value of new material industry will reach more than 50 billion yuan in 2021 In the future, Yinchuan Economic Development Zone will set up an expert advisory committee for new material industry to formulate strategic plans, strengthen "school enterprise cooperation", carry out scientific and technological practical talents training for enterprises, and carry out action plans for the construction of entrepreneur team Http://szb.ycen.com.cn/epaper/ycrb/html/2019-11/08/content_.htm new technology has halved the carbon emission of manufacturing fertilizer: the old process releases more than 450 million tons of carbon every year, accounting for 1% of the total carbon emission of human beings in order to feed 70% of the world With a population of more than 100 million, human beings rely on the Hubble Bosch process with a history of hundreds of years to convert nitrogen in the air and methane in natural gas into ammonia, which is the raw material for making fertilizer But this process emits more than 450 million tons of carbon dioxide every year, about 1% of the total carbon emissions of human beings, more than any other industrial chemical reaction Today, a new ceramic reactor can cut carbon emissions in the process by half In order to make the catalyst work at a higher speed, Vasileios Kyriakou, a chemical engineer at the Institute of basic energy research in Eindhoven, the Netherlands, and his colleagues from Greece, sought a new reactor design that could remove the hydrogen atom immediately after it was stripped from the methane molecule Http://news.scienceet.cn/htmlnews/2019/11/432407.shtm real-time communication, internal and external communication, a system to open the two patent pools of universities and enterprises, university patent results is a set of management system, market enterprise patent is a set of system, which adds obstacles to the transformation of university patent results Recently, Southwest University and Chongqing Zhidong Information Technology Co., Ltd jointly developed Zhidong (zhihuitongyuan) patent management platform, Taking Southwest University as a pilot to improve the efficiency of patent management and promote the transformation of university patent achievements It is understood that with the official launch of the system by Southwest University, Chongqing University, Chongqing University of Posts and telecommunications and College of science and technology have also begun to negotiate Some colleges and universities have launched trials and plans to form corresponding alliances to promote the transformation of scientific and technological achievements of Chongqing colleges and universities http://digitalpaper.stdaily.com/http_
