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 tetrameric cation channels, a phenomenon known as divalent cation block is known to occur: the blocking of ion transport due to the presence of divalent cations such as calcium (Ca 2+) or magnesium ...

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 ...

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 ...

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 ...

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 ...

Study compares calcium phosphate mineralization on polydopamine and zein coated titanium dioxide nanoparticles using quartz crystal microbalance measurements.
