RUDN University agrochemist visualised how plants get phosphorus from the soil

RUDN University soil scientists were able to visualise for the first time the activity of the phosphatase enzyme in the soil surrounding the roots of a plant by simultaneously using zymography and a fibre optic acidity sensor. This helped them to see how the plants “adjust” their root system to the environment. The study was published in the journal Soil Biology and Biochemistry.

RUDN University bioengineers have created nanocontainers for targeted drug delivery

RUDN University bioengineers have created magnetic nanocontainers for “smart” delivery of drugs in the body. Thanks to them, the active substance enters only certain organs or tissues, which reduces the risk of side effects. In an experiment on mice, it was shown that nanocontainers are non-toxic and not dangerous. The results of the study are published in the journal Polymers.

RUDN University chemist creates a catalyst to remove paracetamol from wastewater

A RUDN University chemist has created a catalyst for wastewater treatment that removes paracetamol – one of the most commonly prescribed antipyretics. This medicine is excreted from the body through the kidneys and enters the sewage, where it does not decompose and can pose a threat to people and the environment. The chemist managed to create a catalyst based on silver sulfide, zinc oxide, and graphene oxide to decompose paracetamol under light irradiation. The study is published in the journal Separation and Purification Technology.

RUDN University chemists obtained the antibiotic from chitin

For the first time, RUDN University chemists obtained polymer nanoparticles from chitosan derivatives with antibacterial activity at the level of modern antibiotics. Chitosan is a polyaminosaccharide, which is obtained from chitin and is actively used as a biological additive and cosmetics, but the antibacterial properties of chitosan are expressed quite poor, mainly due to its low solubility in water. Chemical modification of chitosan allows obtaining water-soluble chitosan derivatives with increased antibacterial activity. In this study, chitosan derivatives with extremely high antibacterial activity and significant solubility in water were obtained. To synthesize chitosan derivatives, from which highly active nanoparticles are formed, scientists have developed a new approach based on a combination of click chemistry and ultrasonic processing. With the help of the proposed approach, it will be possible to obtain other polysaccharide particles with antibacterial activity. The article is published in the International Journal of Biological Macromolecules.

Soil scientists from RUDN University have determined the optimal size of soil pores for the activity of microorganisms

Soil scientists from RUDN University found that the most suitable conditions for microorganisms are created in soil pores ranging in size from 60 to 180 micrometers. To visualize the relationship between enzymes produced by soil microorganisms and pore size, researchers first created a three-dimensional map of soil structure. To do this, they used soil 2D zymography and X-ray computed tomography. The article is published in the best soil science journal Soil Biology and Biochemistry.

RUDN University mathematician first described the movement in a flat strip of plasma

RUDN University mathematician for the first time proved the theorem of existence and uniqueness of solutions of the Zakharov-Kuznetsov equation in a strip. Such theorems are very rare for partial differential equations. The new results can be applied, for instance, in astrophysics, in describing the propagation of plane waves in plasma. The article is published in the journal Nonlinear Analysis: Real World Applications.

A molecular "merry-go-round" complex will make OLED screens twice as bright

A RUDN University chemist synthesized fluorescent compounds with "merry-go-round" molecules that can be used to create economical displays with organic LEDs (OLED). The nucleus of these molecules is a triangle of silver or copper atoms, and organic elements are bound to it through phosphorus atoms and are able to rotate around them. This molecular geometry doubled the quantum yield of luminescence to 41 percent. In modern OLED screens, this figure is 20 percent. The article is published in Inorganic Chemistry.

RUDN chemist obtained a reusable catalyst for the synthesis of esters

A chemist from RUDN University has developed a tin silicate catalyst for the production of esters — flavours, plasticisers, and biofuel components. Unlike existing catalysts, the new material can be made active again and reused. The results are published in the journal Microporous and Mesoporous Materials.

Hazardous radiation from “safe” devices: scientists talk about factors that enhance human exposure

Experts from France told RUDN students that the effect of electromagnetic radiation on human organism from such "safe" devices as mobile phones or solar panels can be amplified many times depending on geological conditions and environmental conditions.
