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.
Biologist from RUDN University Morteza Yousefi has found that lavender extract added to the food reduces stress and improves immunity in carp in fish farms. The discovery may be used in fish farming.
Every year in Russia, about 4 thousand children need help of cancer surgeons. The lives of children depend on the professionalism and knowledge of surgeons. RUDN experts share relevant information and many years of experience for the first time in Russia, presenting systemic knowledge of pediatric thoracoabdominal oncological surgery in an encyclopedia published by a professor at the Faculty of Continuing Medical Education of RUDN University, Doctor of medical sciences Andrey Ryabov. The book is edited by the former chief oncologist of Russia, a brilliant oncologist surgeon, legendary academician Mikhail Davydov.
Ecologists from RUDN University studied abandoned vineyards and forests in Italy and found that a high concentration of nitrogen and carbon could be observed in the soil of an old oak forest which was free from anthropogenic stress for about 200 years, while in the soils of vineyards abandoned relatively recently the concentration is many times less. The data show that even Mediterranean soils, affected by humans, can accumulate large amounts of carbon and nitrogen in the process of changing the vegetation community.
RUDN University chemists together with colleagues from other countries synthesized new compounds that effectively bind lead ions and can be used to remove it from wastewater and even from the living organism, that is, to play the role of an antidote for lead poisoning. The article is published in the journal Crystals.
Mathematicians from RUDN University have developed a computational model that allows predicting the mobility of T-lymphocytes, immune cells that recognise and destroy viruses. The model will help, in particular, in the treatment of the immune system disorders, including those that can lead to cancer, and in the development of HIV vaccines.
