N-heterocycles are organic substances used in the chemical industry and medicine. To produce them, expensive catalysts made from noble metals are used. A chemist from RUDN University developed a nanocatalyst for N-heterocycles that consists of zinc oxide and niobium and can be obtained using ...
Catalyst reduces the time of alkylation reactions from several hours to just 10 minutes
Alkylation reactions are used in the petrochemical industry to obtain high-octane number components for gasolines. A chemist from RUDN University found a way to speed this process up to 24 times. To do so, he developed a catalyst based on silica and niobium. The results of his work were published ...
2D organic nanofilms can be used to create protective hydrophobic or anti-corrosion coatings for organic electronics or to develop molecular filters
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 ...
Catalyst based on a substance that comes from plant waste
Many production facilities (e.g. plastic manufacturers, pharma companies, and others) use nanocatalysts that contain palladium--an expensive component that is not sustainably produced. A chemist from RUDN University found a way to reduce palladium consumption and to make its manufacture more ...
Mercury test of catalysts that has been considered universal for 100 years seems to be ambiguous
The mercury test of catalysts that has been used and considered universal for 100 years, turned out to be ambiguous. This conclusion was made by a group of scientists including a RUDN chemist. The group confirmed that the test required additional control experiments to verify its results. The ...
A chemist from RUDN was the first to use catalysts with ruthenium nanoparticles to obtain hydrogen under the influence of visible light and UV radiation. In the future, such catalysts may be used for large-scale production of hydrogen fuel under the influence of sunlight.Photochemical reactions ...
A new type of photocatalysts -- nanostructures from titanium dioxide
A RUDN chemist developed a new type of photocatalysts - nanostructures from titanium dioxide. Hollow nanocubes with ultra-thin walls act like nanoreactors and provide for 28 fold more effective organic reactions at room temperature under the influence of visible light. Traditional methods of ...
It is difficult to study processes at the level of individual atoms and ions at room temperature due to their thermal motion. It causes disturbance that is the reason for considerable inaccuracy of measurements. The main cause of observation errors is the Doppler effect. However, if the atoms are ...
The Diels-Alder reaction is widely used in organic synthesis. Chemists appreciate its simplicity, reliability, and the ability to influence its course and change the conditions of the process. Several products of these transformations are used to create graphene-like materials, product vitamins, ...
A team of scientists from the Research Institute of Chemistry (RIC) of RUDN University together with colleagues from major scientific centers created a new catalyst - a substance that activates oxidation processes in low-reactive components of oil and gas. The new method of hydrocarbon processing ...
