1. St. Petersburg Polytechnic University with the support of the Government of St. Petersburg has opened an application for participation in the online competition of ideas and solutions "Engineers against COVID-19". Applications will be accepted until August 1, 2020. Competitors are invited to develop a BIM-model of a building or its fragment, finding ways to reduce the risk of infection spreading in classrooms and public places.

2. Russian chemists have obtained a new photochromic complex of bismuth(III) with the so-called viologenic cations, capable of changing color under illumination. On the basis of this compound, optical memory elements were created and their high efficiency and stability were demonstrated.

3. Scientists from Skoltech and Moscow State University have identified the processes underlying the operation of the anode material for a new promising class of chemical current sources - sodium-ion batteries(NIA). The obtained data, in conjunction with the method for producing anodes developed by the same group, will make it possible to bring closer the commercialization of NIA in Russia and in the world.

4. Scientists of the Federal Research Center Institute of Catalysis named after GK Boreskov SB RAS have developed a catalyst that can be used in the synthesis of hydrogen fuel, which does not harm the environment. The catalyst invented by chemists is almost not deactivated in the process of producing hydrogen, therefore it can work longer than world analogues.

5. Scientists from NUST MISIS, together with colleagues from the North Caucasus Federal University(NCFU), have developed a unique set of non-destructive techniques for studying diamond materials. The methods will make it possible to determine not only the authenticity of the stone, but also its suitability for use in detectors of heavy charged particles and neutrons, high-power solid-state lasers, as well as for producing diamonds.
