[quick news] on September 19, 2019, black carbon particles were found in the placenta of pregnant women with air pollution or danger to the next generation

Black carbon particles are found in the placenta of pregnant women with air pollution or endangering the next generation of pregnant women A new public science study published in the British journal Nature News: Belgian scientists found that black carbon particles can be found in the placenta of pregnant women exposed to air pollution by high-resolution imaging technology However, further research is needed to determine whether these particles can reach the fetus Black carbon particles are mainly from the burning of fossil fuels, which are released into the air every day Such particles are known to have harmful effects on pregnancy outcomes, for example, they are associated with preterm delivery or low birth weight To improve prenatal care in contaminated areas, it is important to understand how these particles affect pregnancy - directly or indirectly through the mother Https://pubs.acs.org/doi/10.1021/jacs.9b06757 new biological materials are expected to end the "white pollution" At present, the synthetic fiber raw materials commonly used by people come from petrochemical resources, which not only brings convenience to life, but also causes "white pollution" and other ecological environmental problems It has great potential to replace the traditional non degradable plastics with bio based materials Recently, the world's first 1000 ton PLA fiber production line was built in Anhui Fengyuan Group, which is expected to promote the large-scale industrialization of new bio based materials According to reports, bio based materials come from biomass resources Through bio fermentation technology, starch and cellulose in plant roots, stems and fruits are transformed into biological products such as polylactic acid, which are then refined and polymerized to form high molecular environmental protection biomaterials Http://paper.ce.cn/jjrb/html/2019-09/18/content_.htmgeochemists measure the new composition of the earth's mantle what is the chemical composition of the earth's interior? Since it is impossible to drill more than 10 kilometers deep, this information is often provided by melting the volcanic rocks formed in the deep earth Geochemists from the University of Minster in Germany and Amsterdam in the Netherlands investigated the volcanic rocks that make up the Azores in Portugal Their goal is to gather new information about the evolution of mantle composition, which is about 30 to 2900 kilometers deep inside the earth Using sophisticated analytical techniques, they found that the composition of the mantle beneath the Azores was different from previous ideas - suggesting that most of it contained a surprisingly small number of so-called incompatible elements Http://cn.latincomercio.com/investment/20190911486.html Fujian Chemical Engineering Science and Technology Innovation Laboratory of China has recently settled in Quanzhou As one of the first four provincial innovation laboratories constructed in 2019 in Fujian Province, Fujian Chemical Engineering Science and Technology Innovation Laboratory of China has settled in Quanzhou What is Fujian innovation laboratory? What kind of Chemical Engineering Science and technology innovation laboratory should be built in Fujian, China? In an interview, the relevant person in charge of the Municipal Bureau of science and technology said that Fujian innovation laboratory will be the highest level and the highest level of science and technology innovation platform in the province and the "No.1 Project" of science and technology innovation in Fujian Province at present China Fujian Chemical Engineering Science and technology innovation laboratory will be based in Fujian and Quanzhou, facing the whole country and the world, aiming at Fujian Province and Quanzhou as an important base of national petrochemical industry, leading and supporting the high-quality development of petrochemical industry Http://m.mnw.cn/quanzhou/news/2200802.html breakthrough 40 years of technical bottleneck new artificial muscle material research and development success artificial muscle is a new type of intelligent shape memory material, it can stretch, bend, tighten or expand through the change of the internal structure of the material At present, the commonly used artificial muscle materials are piezoelectric ceramics, shape memory alloys, electroactive polymers and so on Recently, a polyurethane / polyacrylate interpenetrating network structure liquid crystal elastomer material has been developed by Professor Yang Hong's research group of School of chemistry and chemical engineering of Southeast University It has super mechanical properties, breaks through the research bottleneck of 40 years, and has a wide application prospect in artificial muscle and other fields The research results were recently published in the international journal Annals of the American Chemical Society https://pubs.acs.org/doi/10.1021/jacs.9b06757
