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.

Roads consist mostly of holes that can be mixed with potholes — that’s how Alex Oganga, a master student from Kenya, describes the village where he spent his childhood. Moscow and Russia impressed him not only with the roads, but also with the organization of traffic and its accuracy. He is studying mathematics, although, to be perfectly honest, since childhood he was attracted to physics and materials science.

As a child, he read Homer’s Iliad, later he flew to Moscow to study the archives, and then published an article in the Byzantine and Modern Greek Studies Journal of the Cambridge University Press. Historian Argirios Tasoulas from Greece speaks about his life.

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.
