RUDN chemists have created catalysts for cheap and efficient synthesis of propylene and ethylene
Propylene is
“We
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
If
“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.

On October 7–10, 2024 RUDN University Space Week traditionally took place. This event was dedicated to the World Space Week, which is celebrated annually in accordance with the UN General Assembly Resolution 54/68 (December 6, 1999) from October 4 to 10 to commemorate the launch of the first artificial satellite Sputnik-1 on October 4, 1957, and the signing of the Outer Space Treaty on October 10, 1967 – the fundamental international treaty in the field of international space law.
A RUDN agrotechnologist has identified wheat genotypes that are resistant to a dangerous fungal pathogen that infects plants even before the snow melts and reduces yields.
RUDN University engineers have calculated the parameters of a system that can prevent lunar power plants from overheating. These developments will be needed when planning for long-term lunar missions and colonizing the satellite.
