1. Scientists from the Institute of Catalysis of the SB RAS, together with colleagues from Yekaterinburg, France and Belgium, were able to describe the size distribution of cobalt nanoparticles using the nuclear magnetic resonance(NMR) method in the internal field of the sample. This is a relatively new technique, and researchers have been able to show its effectiveness in practice. Determining the size of the synthesized cobalt nanoparticles is necessary to increase the efficiency of their use.



2. For the first time, the HSE and Sberbank Discussion Club will open within the framework of the April International Scientific Conference on the Development of Economy and Society - an expert platform where a series of sessions will be held, where representatives of business, science and government, on the basis of scientific knowledge, will discuss current challenges for the economy and society and share best practices in business and institutional development.



3. A group of scientists from the Department of Analytical Chemistry, Faculty of Chemistry, Moscow State University proposed using ordinary chlorophyll, a green plant pigment, as an analytical reagent. As an example of such a determination, in an article published in the journal ACS Sustainable Chemistry and Engineering, they measured the concentration of the antibiotic neomycin in urine.



4. Scientists of the St. Petersburg State University of Industrial Technologies and Design, under the guidance of Honored Scientist of the Russian Federation Professor Alexander Mikhailovich Kiselev, have developed a technology for creating textile materials of any composition that self-clean from contamination under the influence of sunlight or after treatment with water and can have different colors. This destroys both pollution and bacteria and microorganisms.To create fabrics of a new generation, absolutely any textile material is covered with a special coating of interference pigments - nanoparticles based on oxides of titanium, iron, tin, nickel, aluminum, chromium and other metals.



5. The first elements of a space tug with a nuclear power propulsion system have already been manufactured in Russia, the head of Roscosmos Dmitry Rogozin told reporters following a meeting with the president.
