Charged up: revolutionizing rechargeable sodium-ion batteries with 'doped' carbon anodes
Rechargeable batteries like lithium-ion batteries (LIBs) are seeing a surge in demand as technologies like electric propulsion ships and other vehicles become increasingly popular.

In Applied Physics Reviews, researchers describe how they applied basic physical concepts of atomic scale to build high-performance anodes for sodium-ion batteries. (2021-01-12)

RUDN University scientist showed global warming effect on greenhouse gas emissions in paddy soils
A soil scientist from RUDN University studied the decomposition of organic matter in rice paddies--the sources of CO2 and methane emissions. Both gases add to the greenhouse effect and affect climate warming in subtropical regions. The emissions increase when the roots of plants influence microbial communities in the soil. This influence, in turn, depends on temperature changes. Therefore, climate warming can lead to more greenhouse gas emissions. (2020-12-24)
