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.
Advances in hydraulic fracturing technology have enabled discovery of large reserves of natural gas which primarily contains methane, which is mainly burned directly and causing global warming potentially. Upgrading methane to greener energy such as methanol through aerobic oxidation is an ideal way to solve the problem and remain 100% atom economy.
As far as green chemistry is concerned, identifying novel and lasting solutions to the material needs is one of the main targets.
Scientists based at the University of Oxford as part of the Faraday Institution CATMAT project researching next-generation cathode materials have made a significant advance in understanding oxygen-redox processes involved in lithium-rich cathode materials. The paper, published in Nature Energy, proposes strategies that offer potential routes to increase the energy density of lithium-ion batteries.
Scientists recently invented a new approach for optimizing the electrocatalytic performance of palladium (Pd) in ethanol oxidation reaction, which is the main anodic reaction of direct ethanol fuel cells (DEFCs).
Chemical engineering researchers have developed a new catalyst that significantly increases yield in styrene manufacturing, while simultaneously reducing energy use and greenhouse gas emissions.
Army researchers reached a breakthrough in the nascent science of two-dimensional polymers thanks to a collaborative program that enlists the help of lead scientists and engineers across academia known as joint faculty appointments.
