A chemist from RUDN University and his colleagues have proposed using residues from processing bay leaves as raw material for the production of chemically active substances, in particular antioxidants. Researchers have developed a mechanochemical method for the extraction of antioxidants, which reduces processing time by more than 10 times.

Chemists from RUDN University have studied the mechanism of radiation instability of thermoluminophores based on lithium tetraborate, which are used for the manufacture of radiation dosimeters. They found that the properties of the materials are deteriorating due to the breakdown of chemical bonds in the boron-oxygen network and the formation of clusters of manganese, which is part of the substances.

A RUDN University chemist revised the mechanism of the Henry reaction catalyzed by copper(II) complexes. Thus, using new copper(II) complexes (obtained in the same laboratory), he showed that water plays a crucial role in the asymmetric Henry reaction, directly participating in the catalytic cycle of the reaction. Previously, this factor was never taken into account, and all scientists thought that the copper(II) complex works as a classical Lewis acid.

RUDN immunologist came up with recombinant molecules Parietaria judaica pollen’s allergens are needed for allergen-specific allergy-immunotherapy.

RUDN chemist synthesized a fundamentally new catalyst for formic acid photo‑oxidation, which is considered to be the most perspective source of hydrogen for fuel elements. A catalyst based on titanium amorphous oxide is a new instrument for formic acid conversion. In the future, it will allow to abandon traditional costly catalysts based on palladium, platinum, and ruthenium.

RUDN doctors found an increased level of selenium and other significant microelements in wheat bread and wheat from selenium-rich areas. Thanks to this, bread and wheat can be used as a source of selenium for people with selenium deficiency.

The new polyethylene production technology made it possible to double the length of ethylene chains in comparison with those obtained by existing methods for polymers synthesis. To achieve that, the authors synthesised new types of reagents. The results of products structure study obtained by the RUDN University chemist will allow producing more durable and flexible material.

Mathematicians from RUDN University and the Free University of Berlin have proposed a new approach to studying the probability distributions of observed data using artificial neural networks. The new approach works better with so-called outliers, i.e. input data objects that deviate significantly from the overall sample.

A chemist from RUDN University has obtained biologically active derivatives of ferrocene, which stimulate plant growth by 67% and protect them from herbicides.

RUDN University biologist proved that the extract of the fruit of the Chinese date boosts immunity in carp. The addition of date juice to the diet increases the reaction of the immune system of fish to extraneous compounds.

A chemist from RUDN University has created a series of catalysts for click chemistry. These reactions are widely used in the synthesis of biologically active substances, as well as in biological and medical research. New catalysts produce a yield of 99%. They are based on cyclodextrin and copper ions.

A chemist from RUDN University has created platinum complex compounds that are superior in activity to cisplatin, the drug for the treatment of tumour diseases. The new compounds turned out to be also less toxic to healthy cells.
