IEEE challenges academic bottom line and damages academic reputation 29 days ago, a screenshot circulated on social network shows that IEEE (Institute of electrical and electronic engineers, International Association of electrical and Electronic Engineers) sent an email to journal editors, prohibiting Huawei employees from participating in its academic activities as reviewers Immediately after the email was exposed, it caused a stir in the academic circle Zhou Zhihua, Dean of the Institute of artificial intelligence of Nanjing University and IEEE fellow, said directly on his microblog that this is a naked (political) interference in the academic field, "destroying Three Outlooks" Zhang Haixia, a professor at the school of information science and technology of Peking University, wrote to the chairman of IEEE in an open letter Tuesday that the move was far beyond the acceptable bottom line for an academic, "as a member of IEEE and a editorial board member of a journal, I have to show my attitude: I apply to withdraw from the editorial boards of two IEEE journals where I work."

A global problem has arisen The U.S government has begun to auction the radio frequency band of 5g network, the next generation communication network, but some of the spectrum is very close to the working spectrum of some major geodesic satellites This makes meteorologists very worried They think that 5g signal transmission is likely to interfere with normal data collection work and affect the accuracy of global weather forecast According to a report from Nature news, given the large scale of the communication market in the United States, the decision of the U.S government on how to deploy 5g network may also affect the subsequent regulatory policies of other countries NOAA and NASA are in an important negotiation with the Federal Communications Commission, which oversees the distribution of wireless networks in the United States, the paper said NOAA and NASA hope that FCC will participate in protecting the frequency band of earth observation from 5g signal interference Https:// the latest "cousin" of graphene lead ene has been published According to the daily science website of the United States, two-dimensional materials (the "cousin" of graphene) composed of the 14th group of elements have attracted great attention in recent years, because they have the potential to become topological insulators Recently, for the first time, Japanese scientists have made the pure theoretical lead-based two-dimensional honeycomb material, plumbene, a reality Graphene, as a two-dimensional carbon material separated from graphite, has shown its excellent thermal effect, electrical properties, hydrogen absorption at low temperature, no scattering at room temperature, strain sensing and other functions With the rapid iteration of synthesis technology in the field of materials science, the "relatives and friends" of graphene began to come into people's attention, and lead-ene is such an example Due to its unique structure, lead-ene can be said to add a beautiful scenery to the nano nature In the future, the application of lead-ene in touch screen, super capacitor and other electronic products will gradually become a reality Https:// oxygen production or reality on Mars: oxygen can be obtained by hitting gold foil with carbon dioxide According to the report of the US space network on May 28, US scientists designed a reactor by studying how comets produce oxygen molecules, in which they used carbon dioxide (CO2 ）Hit the gold foil and get oxygen They said the new technology is expected to help future manned Mars exploration In addition, NASA is about to test oxygen generation technology on Mars A demonstration platform called the Mars oxygen in situ resource utilization experiment (moxie) will be launched with the Mars 2020 probe next summer and land on Mars in February 2021 Moxie will use electrochemical methods to decompose CO2 in the atmosphere NASA hopes to find out whether this method can expand the scale to support people who may live on Mars in the future Https:// new technology can increase the catalytic speed of chemical reactions by ten thousand times Recently, American researchers have found a new technology that can increase the catalytic speed of chemical reactions to the limit of the existing catalytic speed 10000 times, it is expected to greatly improve the speed of thousands of chemical processes, and significantly reduce costs, so as to benefit fertilizer, food, fuel, plastic and other industries Researchers at the center for catalytic energy innovation, funded by the U.S Department of energy, found that they could break the speed limit by creating oscillating catalysts by applying waves to them Waves have peaks and troughs, and when waves are applied, they allow two parts of the chemical reaction to proceed independently at different speeds When the wave applied to the catalyst surface matches the natural frequency of the chemical reaction, the so-called "resonance" mechanism will lead to a significant increase in the catalytic rate http://digitalpaper.stdaily.com/http_
