Two competitive nucleation mechanisms of calcium carbonate

Four self-assembled monolayer surfaces terminated with -COOH, -OH, -NH 2 and -CH 3 functional groups are used to direct the biomineralization processes of calcium carbonate (CaCO 3) in low Ca 2+ concentration, and the mechanism of nucleation and initial crystallization within 12 h was further explored On −COOH surface, nucleation occurs mainly via ion aggregation mechanism while.
