Since non-classical crystallization pathways were revealed, our picture of nucleation and crystal growth became in the last year quite confusing and ramified: we are confronted with the existence of liquid phases of amorphous calcium carbonate, polymer-induced liquid precursor and, last but not least, pre-nucleation clusters. This contribution explores: (a) The symmetry-breaking phase-selection of calcium carbonate, which is based upon a subtle interplay of interlinked equilibria and is ultimately ascribed to the weak parity violation energy difference. (b) A morphogenetic employment of ...
