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.

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.

Education & Training is one of the priority subject areas that is dynamically developing at RUDN University. Since 2016, the increase in publications has amounted to 114.6%. In total, over the 6-year period, RUDN University researchers published 354 articles on educational topics. Over half of them are published in Open Access journals, which makes the results of their studies available to a wide range of researchers.

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.

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.

Scientific-methodological workshop of the Commission on Foreign Languages of the RUDN University with an external speaker on the basis of the Department of Foreign Languages of the Faculty of Social Sciences and Humanities, the report of Ph.D., Alexandre André Louis Solcà (Switzerland, Lausanne Institute, an independent researcher) in the French language “Intercultural connections and teaching foreign languages for different purposes. How ancient and modern languages can help us in our daily need of social communication” at the Department of Foreign Languages of the Faculty of Social Sciences and Humanities on December 1, 2021.

A soil scientist from RUDN University found out that the resources of organic phosphorus in the soils of the Tibetan Plateau could be depleted because of global warming. To do so, he compared phosphorus content in the soils from the Tibetan Plateau that has a cold climate and from the warmer Loess Plateau.

The traditional mathematical model of predator-prey relations in the wild does not take into account indirect nonlocal interactions. However, according to a mathematician from RUDN University, they affect the dynamics of predators and prey in a system, and the nature of this effect is sensitive to the initial conditions.

A team of chemists from RUDN University synthesized new organosilicon compounds containing terbium and europium ions. These complexes have an unusual cage-like crystal structure that contains four metal ions. The team was the first to study the magnetic and photophysical properties of such compounds and to observe their magnetic phase transition and luminescence properties.

A team of immunologists from RUDN University suggested a new tool to control inflammation levels in asthma patients with coexisting diseases. To obtain information about the course of the disease and risks of complications, they used different types of cytokines found in the patients’ nasal swabs.

The Institute of Modern Languages, Intercultural Communication and Migration (ISLMKiM) started publishing a new online scientific journal “Macroscociolinguistics and Minority Languages”. Chief editor — Svetlana Moskvicheva, Director of IMLICM, associate professor, PhD in Philology.
