A RUDN University chemist has created an unusual carbon structure that can be used as a cathode in zinc-ion supercapacitors. The batteries obtained on its basis have a higher capacity and energy density than existing analogues.
RUDN scientists have clarified the model for calculating the probability that space objects may encounter. Classical models do not take into account the real shape and orientation of objects -it seemed that this increases the calculated probability several times. The results are published in the journal Cosmic Research.
RUDN University biologists proved the effectiveness of biogenic metal nanoparticles against some fungi infecting plants. The nanoparticles are obtained in a safe way from strawberry leaf extract.
RUDN University biologists have proposed a safe and environmentally friendly way to obtain seven types of metal nanoparticles that are necessary for medicine and agriculture. This does not require expensive and toxic chemicals or expensive equipment — the synthesis takes place using an extract from the leaves of Fragaria ananassa.
December 28, RUDN University Rector Oleg Yastrebov and QS World Merit Head of Partnerships Zoya Zaitseva signed an agreement on large-scale cooperation in achieving 17 sustainable development goals identified by the UN.
The paramedic’s task is to provide urgent, emergency medical care to the patient despite of often unfavorable conditions. Rough roads, high vehicle speeds, or poor teamwork do not contribute to saving lives. Medical students can now try real work in an ambulance - an ambulance simulator has been opened at RUDN University accreditation and simulation center.
A chemist from RUDN University suggested an eco-friendly method for the synthesis of dapsone, a substance that inhibits the growth of malaria and leprosy agents. The main component of the new reaction is hydrogen peroxide that does not form environmentally destructive compounds, and the only by-product is simple water. Unlike other technologies, this method includes only one stage of dapsone production and does not require high temperatures. The catalyst of the reaction can be reused without any loss of efficiency.
A chemist from RUDN University used a copper catalyst in the click reaction of triazole synthesis. Triazoles are bioactive substances that are used to treat fungal diseases and synthesize pharmaceutical drugs and also play a role in polymer chemistry. The catalyst not only accelerated the reaction several times but also helped perform it at room temperature and without any bases or solvents. The reaction turned out to be almost 100% effective and had no by-products. The scientist also studied the mechanism of the reaction and identified its differences from a regular click reaction.
In a year, RUDN University rose from 43 to 31 place in the international QS University Rankings: Emerging Europe & Central Asia 2022. Peoples’ Friendship University of Russia showed the best results in international scientific relations, academic reputation and employer reputation categories.
RUDN has risen to the 28th position in the international ranking of environmentally friendly universities UI GreenMetric 2021 remaining the “greenest” university in Russia. This is the best result in the history of the university’s ranking participation since 2011. The list of the “greenest” universities was published on December 14. There are 956 universities from 80 countries, including 54 universities from Russia. The goal of the UI GreenMetric — assess universities according to campus development ecological sustainability and the energy-saving model of university management.
Many production facilities (e.g. plastic manufacturers, pharma companies, and others) use nanocatalysts that contain palladium—an expensive component that is not sustainably produced. A chemist from RUDN University found a way to reduce palladium consumption and to make its manufacture more eco-friendly. He developed a catalyst based on a substance that comes from plant waste. Using his invention, manufacturers could cut palladium consumption in half. Moreover, new catalysts can be reused multiple times without any decrease in efficiency.
