RUDN chemists have created catalysts for cheap and efficient synthesis of propylene and ethylene
investigated how the structure and texture features of HZSM-5 zeolites and their composites with anatase mineral nanoparticles affect their catalytic activity in reactions with propane at high temperature and with liquid ethanol at medium temperature,” — Ekaterina Markova, Candidate of Chemical Sciences from RUDN.
RUDN chemists have created, tested and characterized various modifications of
“The addition of
anatase nanoparticles, the number and volume of pores of different sizes, the content of hydroxyl groups and other characteristics affect the operation of catalysts. This will allow us to control the course of reactions, the mechanisms of which we have also studied. Our catalysts are no less or even more active than commercially available analogues, but they are easier to manufacture. In addition, they are cheaper and allow you to more accurately control the production process of ethylene and propylene,” — Candidate of Chemical Sciences Anna Zhukova, Associate Professor of the Department of Physical and Colloidal Chemistry of the RUDN.
The results are published in
RUDN University chemist proposed a new method to create catalysts on a porous silicon matrix with metal nanoparticles. Efficient catalysts for organic reactions are obtained, for example, for the synthesis of vanillin, which is in demand in the food and perfume industry.
When talking about COVID-19, television, newspapers, magazines, and social media turn to battle metaphors that make the fight against the pandemic feel like a war. Also, the coronavirus is often discussed in an excessively alarming and threatening tone. This problem is so acute that there is even the term for that — infodemia. It describes the panic in the media and social networks. A linguist of RUDN University studied how such a language affects the notions of people regarding COVID-19.
Ecologists of the RUDN University showed that one of the methods used to detect the soil organic matter turns out to be ineffective after precipitation. Studies have shown that the impact of rain on the surface of arable soils leads to a decrease in the accuracy of modelling of organic matter content by 70%. The ecologists also suggested the way to compensate for this negative phenomenon and increase the accuracy of calculations to 84%.
