1. Scientists at the Ural Federal University(UrFU, Yekaterinburg) have developed clay bricks that attenuate ionizing radiation as much as possible, to a level that is safe for the human body. Scientists add waste from the Ural industry to their composition. Bricks are a relatively cheap and convenient material with which you can quickly erect protective rooms, structures, walls around objects with radiation.



2. Skoltech researchers and their colleagues from China and Germany have presented a new search algorithm for single-atom-alloy catalysts(SAACs) that found more than 200 yet unreported candidates. Their work provides a recipe for finding best SAACs for various applications.



3. Skoltech researchers have studied the electronic properties of indium arsenide, a semiconductor that is currently widely used for photodiodes in the infrared range and proposed as a building block for alternative infrared lasers and terahertz oscillators. It has exceptionally high electron mobility and carrier density, meaning that it can process the signal faster at low supply voltage and consequently increase the computation efficiency of a device.



4. The first deputy general director of Roscosmos, Yuri Urlichich, at a round table in Moscow on Wednesday said that the system would have about 380 satellites, which is a third less than previously assumed. Earlier, Roskosmos reported that it will include 542 spacecraft.



5. Development of a group of young scientists under the leadership of an associate professor of the Department of Chemical Technology of Solid Fuel of the Kuzbass Technical State University named after T.F. Gorbachev, member of the Youth Council of the Oil and Gas Industry under the Ministry of Energy of Russia Elena Ushakova is suitable for use in the most severe climatic conditions. Scientists have developed a sorbent to clean up fuel spills in the Arctic. And in China they are looking for a partner for the joint commercialization of the Kuzbass project.
