) Self-epitaxial nucleation induced assembly and supersaturation-driven interfacial
structure mismatch nucleation: the structural match between the daughter crystals and the parent
crystal will become poor as supersaturation increases. An example in calcite crystallization is
demonstrated. (

of supersaturations where experiments were carried out, three straight lines with different slopes
intercept one another, dividing the space into three regimes. (

structural mismatch: with the increase in the supersaturation, the interfacial correlation factor
