A researcher from RUDN University suggested that Xanthomonas bacteria that are harmful to plants might have developed from a nonpathogenic related species by receiving virulence genes from other species of bacteria.
Many substances with different chemical and physical properties, from diamonds to graphite, are made up of carbon atoms. Amorphous forms of solid carbon do not have a fixed crystal structure and consist of structural units—nanosized graphene particles. A team of physicists from RUDN University studied the structure of amorphous carbon and suggested classifying it as a separate type of amorphous solid bodies: a molecular amorphic with enforced fragmentation.
A team of linguists from RUDN University established that a person’s ability to accurately differentiate between vowel sounds of a foreign language correlates with the size of their vocabulary in said language.
A geneticist from RUDN University studied the effect of Bifidobacterium (intestinal bacteria) on the inflammatory process and discovered that their surface protein is capable of stopping excessive or uncontrollable inflammation, like the one observed in COVID-19 patients. A fragment of this protein can be used as an anti-inflammatory medication when treating coronavirus and other diseases.
A chemist from RUDN University together with colleagues created a new type of two-dimensional nanofilm from an organic material called calixarene. The invention can be used as a protective coating in electronics and as a part of molecular filters. They also suggested a way of increasing the durability of such films with UV radiation.
A biologist from RUDN University confirmed that selenium nanoparticles and garlic extract can effectively reduce the negative impact of stress on the health of grass carp in the breeding industry.
A team of mathematicians from RUDN University found a way to reduce the size of a trained neural network six times without spending additional resources on re-training it. The approach is based on finding a correlation between the weights of neural connections in the initial system and its simplified version.
Individual characteristics of the shape and cross-section of the root canal are one of the main issues for dentists. When treating a root canal, a doctor needs to properly clean it, fill it, and carry out a rebuilding procedure so that a canal is sealed. The first stage of endodontic treatment requires detailed knowledge of root canal anatomy. A team of dentists from RUDN University studied and classified various changes in root canal shapes. The new classification will help doctors avoid diagnostic errors, better select their tools, and treat patients more efficiently.
An international team including chemists from RUDN University suggested an economically feasible and environmentally friendly method to synthesize surfactants. The new compounds can become an eco-friendly alternative to traditional chemicals used in oil production, skincare products manufacture, and in the pharmaceutical industry to transport drugs to diseased body tissues.
A professor from RUDN University together with his colleagues from Saratov Chernyshevsky State University and D. Mendeleev University of Chemical Technology of Russia developed a method for calculating the parameters of diffraction optical elements used in LCDs. In particular, the new technology can be used to expand the angle of view while preserving high resolution and color rendition.
A professor from RUDN University together with his Indian colleagues synthesized and studied new dibenzophenazine-based liquid crystals that could potentially be used in optoelectronics and solar panels.
A team of chemists from RUDN University created an antibacterial coating for food products. The mixture consists of two components that are safe for human health and form a thin, non-toxic, and biodegradable film. The film has no color or flavor and can increase the shelf life of different products 2.5 to 8 times.
