Alan Turing, who is considered as the father of computer science and artificial intelligence, hypothesized in 1952 that some repetitive natural patterns may be generated by the interaction of two particular substances via the “reaction-diffusion” process.
Employees of the Samara Center for Theoretical Materials Science (SCTMS) of Samara Polytech together with scientists of Northwestern Polytechnical University (NPU, China) generated low-energy carbon allotropes, i.e. substances of the same composition as the known allotropes, such as graphite or diamond, but different in structure and properties.
The current commercial production of methanol through the hydrogenation of the green-house gas CO2 relies on a catalyst consisting of copper, zinc oxide and aluminum oxide. Even though this catalyst has been used for many decades in the chemical industry, unknowns still remain.
By embedding a silver catalyst inside a porous crystal, KAUST researchers have improved a chemical reaction that converts carbon dioxide (CO2) into carbon monoxide (CO), which is a useful feedstock for the chemical industry.
Japanese researchers have developed a simulation method to theoretically estimate the performance of heterogeneous catalyst by combining first-principles calculation (1) and kinetic calculation techniques. Up to now, simulation studies mainly focused on a single or limited number of reaction pathways, and it was difficult to estimate the efficiency of a catalytic reaction without experimental information.
Scientists from the Skoltech Center for Design, Manufacturing and Materials (CDMM) and the Institute for Metals Superplasticity Problems (IMSP RAS) have studied the fatigue behavior of additive-manufactured high-entropy alloys (HEA). The research was published in the Journal of Alloys and Compounds.
Lithium-ion battery fire hazards are extensive worldwide and such failure can have a severe implication for both smartphones and electric cars, says the head of the group and Professor in the Department of Electrochemistry at St Petersburg University Oleg Levin.
Metrohm USA is pleased to announce the winner of its 2021 Young Chemist Award, Ryan Jansonius. Ryan is a PhD candidate at the University of British Columbia where his research centers around developing technologies that use inexpensive and abundant renewable electricity to drive otherwise environmentally costly chemical transformations.
Physically confined spaces can make for more efficient chemical reactions, according to recent studies led by scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory. They found that partially covering metal surfaces acting as catalysts, or materials that speed up reactions, with thin films of silica can impact the energies and rates of these reactions.
Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution.
