[quick news] on February 22, 2019, postgraduate entrance examination was accused of deliberately grading, and the first normal university responded that the procedure was standardized

The postgraduate entrance examination was accused of deliberately grading In response, the first normal university said that since February 19, the procedure had been standardized Many netizens posted that the specialized courses were graded by the Capital Normal University, and said that the school was doing this to collect 985 and 211 students To this end, the official response of the first normal university said that the examination papers were strictly carried out in accordance with the provisions of the Ministry of education and other regulations, and there was no intentional grading According to the relevant regulations of the Ministry of education and Beijing Education Examination Institute, candidates who have any objection to their personal performance can apply to the Graduate School of the University for performance review in written form The results review only checks whether there is any missed judgment, accumulated results and registration errors on the paper The school will carry out performance review in accordance with relevant regulations, and will not accept other review applications, and will not accept the application within the time limit Http://epaper.ynet.com/html/2019-02/21/content_.htm? Div = - 1 Chinese and foreign research teams have made new progress in the research of metal carrier interface structure recently, Zhou Yan, associate researcher, Shen Wenjie, National Key Laboratory of catalysis foundation, Dalian Institute of chemical science, Chinese Academy of Sciences, Wang Yuemin, Professor of Karlsruhe Institute of technology and Jens, topso, Denmark Dr sehested and others have made important progress in the research of active site atomic structure and reaction mechanism of copper catalyst The team characterized the atomic structure and chemical coordination environment of the metal carrier interface by using the spherical aberration positive scanning transmission electron microscopy and the electron energy loss spectrum It was found that the copper cluster mainly presents a double-layer structure, and the spatial structure of the copper atom at the interface depends on the degree of interaction between the copper atom and the oxygen hole on the surface of ceria This study provides experimental and theoretical basis for the development of highly active catalysts by regulating metal oxide interaction Https://www.nature.com/articles/s41929-019-0226-6 Ministry of Education: it has never been approved for universities to hold non local campuses The Ministry of Education recently published a reply on the official website to the first meeting of the 13th National Committee of the Chinese people's Political Consultative Conference on strengthening the top-level design of National University layout As for the problem of running schools in different places in the expansion of colleges and universities, the Ministry of Education said that it has never been in favor of colleges and universities to hold different campuses, and in principle, it will not be approved As for the problems of blind expansion of colleges and universities, setting up different campuses, overall or partial relocation and so on, the Ministry of education believes that China's higher education has entered the connotative development stage with the improvement of quality as the core, and it is not suitable to expand the scale blindly Http://finance.chinanews.com/gn/2019/02-21/8760779.shtml scientists who hope to make water on the surface of the moon with the help of the solar wind US National Aeronautics and Space Administration (NASA) have found that when the current of charged particles called the solar wind irradiates the surface of the moon ball at a speed of 450 km / s, it will make its surface rich in compounds that can make water Scientists have simulated the chemical reactions that may occur when the solar wind strikes the moon's surface, and found that the protons in the solar wind interact with the electrons on the moon's surface to form hydrogen atoms These atoms then migrate through the surface and attach to silicon dioxide and other oxygen-containing molecules that make up the lunar soil Hydrogen and oxygen combine to form the structural component of water - hydroxyl Therefore, with the help of the solar wind, it is expected to produce water on the moon's surface, which will contribute to the construction of the moon base in the future Https://www.sciencedaily.com/releases/2019/02/190220121932.htm new drop like substance: non crystal, non liquid, non liquid crystal Researchers at Tokyo University of technology have discovered a kind of chiral molecule, which can spontaneously form droplets with single crystal regular structure and can rotate and flow in one direction without destroying the structural order, but it is neither crystal, nor liquid or liquid crystal The researchers designed the triphenylene derivatives with side chain chiral ester group, studied their phase transformation action and aggregation structure, and found that the intermediate phase of the substance overlapped two-dimensional films with herringbone structure, forming a three-dimensional structure similar to that of single crystal Under the action of gravity, the droplet like material can maintain the structural order while rotating in one direction and flowing down at the same time Through precise analysis, the researchers found that this unidirectional rotational flow is realized by the chirality of molecules http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-02/21/content_414996.htm?div=-1
