Calcium signalling is activated by calcium ions that are released from intracellular stores, or enter the cell via plasma membrane ion channels. Calcium is an important second messenger that ...

Protons break apart the calcium silicate to form solid silica (SiO2) and calcium ions (Ca 2+). The calcium ions react with CO 2 from the air and hydroxide ions in the water to form into solid, ...

The newly developed hydrogel precursor comprises alginate (natural polysaccharide derived from brown algae), RGD peptide-containing mussel adhesive protein, calcium ions, phosphonodiols, and a ...

Adsorption, ion exchange, solvent-based and membrane options are all moving from pilot and ... The agreement includes a guarantee of more than 95% lithium recovery from the brine, and more than 99% ...
