Sodium Batteries Take a Leap Towards the Grid

Lithium-ion batteries may dominate today’s clean energy storage, but they come with problems: they rely on scarce lithium and cobalt, and their costs are tied to volatile supply chains. That is why researchers have long looked to sodium — far more abundant and geographically widespread — as a promising alternative. Until now, however, sodium metal … Continue reading Sodium Batteries Take a Leap Towards the Grid

Forest Soils Trap Microplastics from the Air

Microplastics — tiny fragments of plastic less than a millimeter across — are now firmly embedded in one of the least disturbed ecosystems in Europe: forests. A new study by researchers at the Technical University of Darmstadt finds that forest soils in central Germany are accumulating significant amounts of these particles, largely through the simple … Continue reading Forest Soils Trap Microplastics from the Air
