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 ...

Researchers at Kanazawa University report in Nature Communications how calcium ions can block sodium ion channels located in cell membranes. Structural analysis and computer simulations made it ...

Researchers simultaneously substituted calcium at the bismuth site and ruthenium or iridium at the iron site to suppress the cycloidal spin structure, enabling room-temperature weak ferromagnetism and ...

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 ...

Calcium is the third most abundant metal in the earth’s crust. It is trimorphic in structure and its hardness is greater than that of sodium. It is less chemically reactive than alkaline metals. The ...

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 ...
