[quick news] July 30, 2019 Tsinghua University: students sponsor international micro nano science conference

Tsinghua University: students initiated the international micro nano science conference recently The 13th International micro nano science student conference was held in Tsinghua University 120 university students from China, Norway, Israel, Sweden and other countries gathered in Tsinghua to focus on the challenging and difficult issues in the field of micro nano science and launch a "brainstorming" International Student Conference of micro and nano science is a global exchange conference sponsored and held by students, which enjoys a high reputation and influence in Europe This year, the conference came to China for the first time from Europe The conference was organized by the undergraduates of Qian Xuesen's mechanics class of Tsinghua University, and more than 30 students from 14 departments of Tsinghua University participated in the preparation Different from previous sessions, this year's conference opened a new "x-idea workshop", which aims to mobilize students from different disciplines to explore unknown problems Http://paper.jyb.cn/zgjyb/html/2019-07/30/content.Htm? Div = - 1 new research shows that most of the nutritional supplements have no health care effect Researchers of Johns Hopkins Medical Center in the United States collected data of nearly 1 million subjects in the world, conducted 277 clinical trials and evaluated 16 The relationship between vitamin, mineral and death and cardiovascular disease The researchers also analyzed the health effects of eight diets, including low-fat diet, low salt diet and Mediterranean diet The results showed that most of the supplements, including complex vitamins, selenium, vitamin A, vitamin B6, vitamin C, vitamin E, vitamin D, simple calcium and iron, could not prevent heart disease or prolong life, but they were harmless to human body Only a low salt diet, omega-3 fatty acids (fish oil) and folate supplements are good for some people's health, while calcium plus vitamin D complex supplements may slightly increase the risk of stroke Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 The new technology is expected to make amputees more flexible to use the prosthesis with better technology at present, which can detect the muscle movement of the stump through electrodes, and convert it into signals to control different actions However, this way is susceptible to a variety of factors, including sweating, strenuous exercise and so on Researchers from Vienna Medical University, Austria, Imperial College of technology and other institutions cooperate to implant a small wireless charging electrode device into the stump through surgery, so that amputees can control the prosthesis more flexibly and efficiently, which helps to improve their quality of daily life In the two years after the surgery, patients found that they were able to control the prosthesis more freely and with much higher accuracy, the researchers said Https://robotics.sciencemag.org/content/4/32/eaaw6306 release of selected results of "Macao Young Scholars Program" in 2019 According to the agreement on the joint cultivation of postdoctoral researchers by the office of the National Postdoctoral Management Committee and the Macao Association of science and Technology (hereinafter referred to as the "Macao Young Scholars plan"), the office of the National Postdoctoral Management Committee and the Macao Association of science and technology in April and June of this year respectively organized experts in Beijing and Macao for 2019 The materials of applicants for the annual "Macao Young Scholars Program" were reviewed, and 30 candidates and 5 candidates for funding were finally determined The office of the National Postdoctoral Management Committee provides a subsidy of 300000 yuan per person, which can be used for the living expenses, housing subsidies, medical insurance, etc of the selected personnel, and is transferred to the selected personnel by the mainland dispatched units on a monthly basis The selected personnel shall go to Macao for postdoctoral research within 6 months after the issuance of this notice If they fail to do so, they shall be deemed to have given up their qualifications Http:// Wang Qidong, a famous material scientist and former vice president of Zhejiang University, died at the age of 99 Wang Qidong, a famous material scientist and educator in China, a member of the Standing Committee of the Eighth National People's Congress, a deputy director of the fifth, sixth, seventh and eighth standing committees of the Zhejiang Provincial People's Congress, a deputy of the Ninth National People's Congress, a member of the fifth, sixth and Seventh Central Committee of the NLD, a member of the fifth, sixth and seventh main committees of the Zhejiang Provincial Committee of the NLD, and a former vice president and professor of Zhejiang University, was invalid due to illness in July 2019 He died in Hangzhou at 12:30 on the 29th at the age of 99 Wang Qidong is a pioneer in the field of material science and engineering education in China For decades, he has been devoted to education and scientific research in material science and Engineering: from the end of 1950s to the end of 1960s, he was engaged in the research of cupola strengthening; from the beginning of 1970s to the end of 1970s, he was engaged in the research of casting high-speed steel and precision casting high-speed steel cutting tools; since the end of 1970s, he has been engaged in the research of hydrogen storage materials and their applications https://
