Self-organized spatial patterns of carbonate formed via a nonclassical crystallization pathwayElectronic supplementary information (ESI) available: Full description of experimental methods and supplementary data and figures. See DOI: 10.1039/c6ce01744d

Self-organized spatial motifs of calcium carbonate with banded or concentric ring patterns are presented here through a cationic polyelectrolyte-induced nonclassical crystallization process in combination with synergistic strontium ions. Remarkable three dimensionally coaxial motifs with analogous pleated and terraced stereoscopic bands have been presented herein via a cationic polyelectrolyte-induced liquid precursor process with synergistic strontium ions. This may provide a fascinating model to understand the growth of crystalline surface topographic structures.
