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.

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.
