Biomineralisation by earthworms - an investigation into the stability and distribution of amorphous calcium carbonate
(2015)BACKGROUND: Many biominerals form from amorphous calcium carbonate (ACC), but this phase is highly unstable when synthesised in its pure form inorganically. Several species of earthworm secrete calcium carbonate granules ... -
Is bicarbonate stable in and on the calcite surface?
(2016)We have used density functional theory with the COSMO-RS implicit solvent model to predict the pKa for the deprotonation of bicarbonate to carbonate, i.e. HCO3− <=> CO32− + H+, when HCO3− is included in, and adsorbed on, ...
