[quick news] on October 31, 2019, scholars from many universities in Hong Kong were supported by the national fund for outstanding young scientists

Scholars from a number of universities in Hong Kong have been granted 25 places to apply to young scholars in Hong Kong and Macao from this year 21 scholars from six universities, including the University of Hong Kong and the Chinese University of Hong Kong, have been selected, with a subsidy of 1.3 million yuan each Many of the selected research projects involve medicine and life sciences Hui Xiaoyan, assistant professor of the Department of internal medicine, Medical College of Hong Kong University, explored the molecular mechanism of white fat browning in depth to provide the basis for the treatment of obesity and metabolic diseases Lu Ailian, an assistant professor in the Department of chemical pathology of CUHK, looked for transcription factors that regulate angiogenesis and immune cell function in order to further understand the pathogenesis of diabetic vascular diseases Http://m.xinhuanet.com/2019-10/29/c_.htm graphene "bottoming" Chinese scientists prepare high-speed transistors For the first time, researchers from the advanced carbon materials research department of Shenyang National Research Center of materials science, Institute of metals, Chinese Academy of sciences have prepared a vertical structure transistor "Silicon graphene germanium transistor" with a Schottky junction as the emission junction The delay time of the graphene base region transistor has been successfully shortened by more than 1000 times, and its cut-off frequency has been changed from megahertz (MHz ）It is expected to be used in high-speed devices in terahertz (THz) in the future The research results were recently published online in nature communication At the same time, Chinese researchers analyzed all kinds of physical phenomena of the device, and found that the device has the potential to work in terahertz field based on the experimental data modeling, which will greatly improve the performance of graphene based transistor, and lay the foundation for the ultimate realization of ultra-high speed transistor in the future Http://digitalpaper.stdaily.com/http_ / 30 / content_ HTM? Div = - 1 new research progress of Alzheimer's disease: uncovering the structure of β - amyloid fibrils A neuroscience study carried out by a team of German scientists first reported the structure of β - amyloid fibrils isolated from the brain tissues of patients with Alzheimer's disease and cerebral amyloid vascular disease This result provides a new understanding of the structural basis of Alzheimer's disease and is also helpful for the development of related drugs The research was published in the British journal Nature communication on the 29th In the three patients' samples, the research team found three different but structurally related forms of β - amyloid fibrils, and determined the molecular structure of one of them This structure highlights the importance of characterizing patient derived amyloid fibrils In addition, the study will help to understand the effect of mutations caused by Alzheimer's disease on β - amyloid protein, and will help to develop drugs to prevent the formation of such fibrils in the future Http:// the world's top scientists' Association, officially unveiled the Shanghai center at the opening ceremony of the second world's leading scientists forum The world's top scientists' Association Shanghai center officially unveiled and released the world's top scientists' scientific community program to the world Many Nobel laureates will establish international joint laboratories in this community to build a scientific "base" with industrial transfer and transformation capabilities At present, a number of top Nobel Prize scientists have joined the base, and the project involves frontier scientific research fields such as biomedicine, artificial intelligence, new energy, new materials, quantum science, etc The laboratory base will also assist the scientific community to set up the technology Bank of cutting-edge science and technology, initiate the establishment of the scientist growth fund, etc., providing a long-term communication space with the world's top scientists for the scientific youth, and help the cultivation of young scientists Http:// high activity and high stability acid oxygen evolution catalyst designed Yao Tao, Professor of National Synchrotron Radiation Laboratory of University of science and technology of China, and Yang Jinlong, Professor of School of chemistry and materials science, jointly worked together to accurately detect the dynamic change process of catalytic active sites of ruthenium based monoatomic catalyst in the process of acid electrochemical oxygen evolution for the first time Based on this, a highly active and stable acid oxygen evolution catalyst was designed Published online in nature communication This discovery provides the experimental basis for the practical application of pemwe in the future to develop new efficient and stable catalysts, and also provides theoretical guidance for the study of the dynamic process of the surface / interface of catalytic materials at the atomic scale http://digitalpaper.stdaily.com/http_
