Global demand for lithium is climbing faster than new mines can open, raising fears that battery supply could bottleneck the clean‑energy transition. A new calcium‑ion battery reported in a ...

Pyroxenes are a major group of rock-forming minerals. Scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals. The ...

In a recent study posted to the bioRxiv* preprint server, researchers investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope (E) protein activity in terms of calcium ...

Lithium has reigned in the battery world for decades. Researchers have tried for years to make a cheaper, more sustainable successor to lithium-ion batteries by using the element’s more common ...
