Even the well-known can sometimes surprise. Calcium carbonate (CaCO 3), also known colloquially as lime or chalk, is a mineral that has already been thoroughly analysed by chemists.But chemistry books ...

Calcium is an essential component of the catalyst that forms oxygen from water during photosynthesis. It seems that part of calcium's job is to enable the release of oxygen from this catalyst.

Calcium Aluminate Hydrates. Three important calcium aluminate hydrates develop during HAC hydration, namely two meta-stable phases, C 2 AH 8, and CAH 10, and the stable phase C 3 AH 6 (katoite or ...

Biochemists have uncovered the structure of cellular mechanism tied to thought, movement and other bodily functions. New atomic scale images of the structure of calcium's gatekeeper, IP3R, could ...
