Research Provides Deeper Insight into Oxidation Processes in Combustion Engines and in the Atmosphere

Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities.

New Catalyst Could Enhance the Longevity, Performance of Lithium-Sulfur Batteries

At the heart of most electronics today are rechargeable lithium-ion batteries (LIBs). But their energy storage capacities are not enough for large-scale energy storage systems (ESSs). Lithium-sulfur batteries (LSBs) could be useful in such a scenario due to their higher theoretical energy storage capacity. They could even replace LIBs in other applications like drones, given their light weight and lower cost.

Rare Metal Complex of N2O Could Help Degrade Potent Greenhouse Gas

Nitrous oxide (N2O), similar to its chemical relative carbon dioxide (CO2), is a major greenhouse gas and is also the leading ozone-depleting substance produced in the 21st Century.

Scientists Use Iodine in the Synthesis of New Stable Crystalline Chalcogenides

A chemist from RUDN University, working with a group of colleagues, synthesized three new chalcogenides (compounds that contain metals and elements from group 16 of the periodic table). The team suggested an unusual approach to synthesis that was based on iodine. An article about the work was published in the Dalton Transactions journal.

Two-Step Amination Strategy Enhances the Intrinsic Activity of CO2 Electrocatalytic Reduction

Carbon dioxide (CO2) electrocatalytic reduction driven by renewable electricity can solve the problem of excessive CO2 emissions. Since CO2 is thermodynamically stable, efficient catalysts are needed to reduce the energy consumption in the process.

New X-Ray Study Resolves How Metals and Oxygen Facilitate Charge Storage at High Voltage

High energy storage batteries for EVs need high capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes but understanding how the magnesium and oxygen accommodate charge storage at high voltages is critical for their successful adaption.
