Fig. 3. Coexistence of enantiomorphs of hierarchically organized vaterite helicoids induced by a single amino acid enantiomer (l-Asp) at high supersaturation conditions.

SEM images of small, counterclockwise vaterite helicoids (short green arrow) having inclined platelets, medium clockwise helicoids (yellow) having vertical platelets, and large counterclockwise helicoids (long green arrows) having vertical platelets.
