[Express News] on September 18, 2018, the hydrogen power train was put into use for the first time: only water vapor was discharged

Hydrogen power train is put into use for the first time: only water vapor is discharged According to reports, hydrogen power train is put into use in Germany for the first time The train provides power through hydrogen and oxygen, and the only emission is water vapor The eco-friendly hydrogen powered train can run 620 miles on a single tank of fuel Compared with the traditional fossil fuel vehicles, the single vehicle cost is more expensive but the operation cost is low, and will greatly reduce the environmental pollution In 2021, 14 vehicles will be put into transportation Https:// Ns'mchannel = rss & ITO = 1490 & ns'campaign = 1490 world artificial intelligence conference was held in Shanghai, and the 2018 World Artificial Intelligence Conference of "drag show" was kicked off on September 17 The leaders of domestic technology giants such as Baidu, Alibaba, Tencent and so on were on the same stage for "drag show", and there were also academicians of Turing Award on the scene Ma Yun, chairman of Alibaba Group's board of directors, said in his speech that in the future, data will be means of production, computing will be productivity, the Internet will be relations of production, and the intelligent era will be a huge social change based on these changes According to Ma Huateng, chairman and CEO of Tencent, today's AI is still in the early stage of development In the future, AI is likely to become a universal key to unleash the potential of human technology and tools in the past, which will bring us unprecedented challenges Robin Li, founder and chairman of Baidu, and CEO, said in his speech that no future company could claim that it doesn't matter to AI Companies that can't embrace AI, use AI, and transform through AI will die Fraser Stoddart, winner of the http://digitalpaper.stdaily.com/http_ Div = - 1 Nobel Prize, was hired as a consultant professor of Beijing University of technology A few days ago, a high-end academic forum to explore the new frontier of chemistry was held in Beijing University of technology At the meeting, Fraser Stoddart, a 2016 Nobel Prize winner in chemistry, a professor of Northwestern University in the United States and one of the most outstanding scientists in the field of international organic supramolecular chemistry and nanoscience, was officially invited by Beijing University of science and technology as a consultant professor of the University, and an academic master of the innovation base for introduction of special molecular nanoscience and Technology ("111" base) Long Teng, vice president of Beijing University of technology, awarded Stoddart an appointment letter and spoke highly of his academic achievements Stoddart expressed that he is willing to introduce the world's outstanding talents to Beijing Institute of technology and build a bridge between Beijing Institute of technology and the world Http://news.scienceet.cn/sbhtmlnews/2018/9/339238.shtm scientists found air pollution particles in the placenta of pregnant women According to reports, the latest results of a research team composed of researchers from several British universities show that toxic and harmful air is closely related to fetal injury Air pollution particles can spread through the lungs of pregnant women and remain in the placenta The study involved mothers living in the London area and found smoke gray particles in every placenta Scientists say the particles are likely to enter the fetus A series of previous studies have also shown that air pollution significantly increases the risk of premature delivery and low birth weight, which can seriously lead to lifelong health damage Https:// programming artificial hydrogel is expected to open up a new avenue for biologic robotics and tissue engineering According to the latest issue of Nature Communications, researchers at University of Texas in A Ling (UTA) have developed a new method for two-dimensional (2D) The hydrogel is programmed to expand and contract in a space and time controllable manner, forming a complex 3D shape and achieving motion The potential applications of this technology include bionic flexible robots, artificial muscles (flexible materials can change their shape or move in response to external signals like human muscles) and programmable materials https://
