RUDN University chemist created a catalyst from orange peel for organic compounds production
27-Oct-2020
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 ...
Chemist created a niobium-silica catalyst to boost petrochemical reactions
Catalyst reduces the time of alkylation reactions from several hours to just 10 minutes
08-Oct-2020
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 ...
Chemist developed a new type of one-molecule thick water-repellent film
2D organic nanofilms can be used to create protective hydrophobic or anti-corrosion coatings for organic electronics or to develop molecular filters
14-Sep-2020
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 ...
Chemist developed a green catalyst for pharmaceutical and industrial chemistry
Catalyst based on a substance that comes from plant waste
08-Sep-2020
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 ...
Disproving the universal nature of the mercury test
Mercury test of catalysts that has been considered universal for 100 years seems to be ambiguous
26-Oct-2018
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 new nanocatalyst for obtaining hydrogen
19-Oct-2018
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 ...
Nanoreactors to synthesize organic substances under visible light
A new type of photocatalysts -- nanostructures from titanium dioxide
11-Oct-2018
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 ...
Russian and German physicists developed a mathematical model of trapped atoms and ions
18-Sep-2018
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 ...
Diels-Alder reaction changes direction completely
29-Jun-2018
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 new catalyst for oil and gas processing
21-Nov-2017
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 ...
