RUDN University chemists discovered the mechanism of radiation instability of lithium tetraborate

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.

RUDN University chemist showed that water plays a crucial role in the mechanism of the Henry reaction catalyzed by new copper complexes

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.

A chemist from RUDN came up with a new catalyst for fuel synthesis

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.

A chemist from RUDN University and TIPS RAS analysed a new way to make heavy-duty polyethylene

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 proposed a new way of using neural networks for working with noisy high-dimensional data

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.
