Ionization energy is one of the most important physicochemical parameters. It is defined in terms of the amount of energy required to rip an electron from an atom. The dependence of the ionization energy on the atomic number determines the periodic law of chemical elements, which is assumed to be ...
"The developed methodology can be easily adapted to designing new functional materials for various applications"
Skoltech researchers and their colleagues from China and Germany have presented a new search algorithm for single-atom-alloy catalysts (SAACs) that found more than 200 yet unreported candidates. Their work provides a recipe for finding best SAACs for various applications. Single-atom-alloy ...
What makes them different is that they can be easily recycled
Researchers at the Laboratory of Cluster Catalysis at St Petersburg University have synthesised polymers from biomass. What makes them different is that they can be easily recycled. Today, our life is simply unthinkable without polymers. Plastics, fibres, films, paint and lacquer coating - they ...
Moreover, it is safer in terms of potential fire hazards and has a lower environmental impact
It is difficult to imagine our daily life without lithium-ion batteries. They dominate the small format battery market for portable electronic devices, and are also commonly used in electric vehicles. At the same time, lithium-ion batteries have a number of serious issues, including: a potential ...
Promising alternative to graphite
The scientists of the National University of Science and Technology "MISIS" (NUST MISIS) being a part of an international team of researches managed to increase the capacity and extend the service life of lithium-ion batteries. According to the researchers, they have synthesized a new ...
Higher accuracy for biological samples and complex mixtures
Mass spectrometers are widely used to analyze highly complex chemical and biological mixtures. Skoltech scientists have developed a new version of a mass spectrometer that uses rotation frequencies of ionized molecules in strong magnetic fields to measure masses with higher accuracy (FT ICR). The ...
A new type of palladium catalysts based on chitin can be reused over 10 times
Chemists from RUDN University synthesized soluble biopolymers based on chitin from crab shells. Together with palladium, they form effective catalysts for organic reactions, and their nanoparticles can be re-used over ten times. Palladium-based catalysts are used to speed up cross-coupling ...
Indirect measurements are a lucky alternative for a variety of sectors
A group of Skoltech scientists developed machine learning (ML) algorithms that can teach artificial intelligence (AI) to determine oil viscosity based on nuclear magnetic resonance (NMR) data. The new method can come in handy for the petroleum industry and other sectors, which have to rely on ...
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 ...
