RUDN University chemist proposed a new method to create catalysts on a porous silicon matrix with metal nanoparticles. Efficient catalysts for organic reactions are obtained, for example, for the synthesis of vanillin, which is in demand in the food and perfume industry.
When talking about COVID-19, television, newspapers, magazines, and social media turn to battle metaphors that make the fight against the pandemic feel like a war. Also, the coronavirus is often discussed in an excessively alarming and threatening tone. This problem is so acute that there is even the term for that — infodemia. It describes the panic in the media and social networks. A linguist of RUDN University studied how such a language affects the notions of people regarding COVID-19.
Ecologists of the RUDN University showed that one of the methods used to detect the soil organic matter turns out to be ineffective after precipitation. Studies have shown that the impact of rain on the surface of arable soils leads to a decrease in the accuracy of modelling of organic matter content by 70%. The ecologists also suggested the way to compensate for this negative phenomenon and increase the accuracy of calculations to 84%.
RUDN University mathematicians have proposed a model for a service system in which one server processes multiple request streams. Unlike analogues, new model forbids to interrupt the operating of the request, even if the time allocated for the stream, in which it arrives, has expired. The results can be used, for example, in banking.
A RUDN physician and Russian scientists investigated for the first time the long-term effects of treating diabetic ulcers with stem cells. Doctors concluded that despite the positive effect in the early stages of healing, this technique needs to be improved.
RUDN University chemist with colleagues from India and Korea created a nanofilter for water purification from synthetic dyes. The graphene-based composite can quickly remove up to 100% of harmful compounds from water, and it can be used up to seven times without losing efficiency. In addition, the synthesis of the nanofilter itself is economical and environmentally friendly.
People who were born prematurely, with a lower body weight and growth delays in the womb, are more likely to suffer from disorders of neuropsychological development. RUDN doctors have proposed and tested a method by which deviations can be detected in the first weeks of life.
RUDN University chemist, together with colleagues from Korea and India, has created a reusable nano filter that can absorb harmful compounds from wastewater. Moreover, it works simultaneously for organic and inorganic pollutants.
RUDN chemists have created a biodegradable polymer based on chitosan and polyhydroxybutyrate. Chitosan, which is obtained from animal shells and fungal cells, gives the compound antimicrobial properties, so it can be used for disposable medical and hygienic materials and products.
RUDN University professor together with colleagues from France and the USA has developed a technique for describing blood clotting regarding the individual characteristics of patients. This will help to make more accurately diagnosis and select drugs dosages for the treatment of haemophilia, thrombosis and other blood coagulation disorders.
RUDN chemists have proven the effectiveness of metal complexes for catalysis of cyanhydrin production — substances important for the chemical industry. Chemists managed to achieve 96.3% of the reaction efficiency.
RUDN University chemists obtained a metal-containing complex with an unusual planar architecture. The unexpected structure was formed due to the spontaneous fixation of carbon dioxide from the air during the reaction. This compound exhibits unusual magnetic properties (spin glass behaviour). This can be useful for creating memory storage devices.
