| Abstract: | One crystalline phase can exhibit different morphologies and growth orientations. Unit cell is the basic unit for the construction of crystals and the growth directions of the crystals are related to the macroscopic morphologies and properties of the crystals significantly. By combining the crystallography theory, experimental results and software simulation, we discussed the mechanism for the formation of different morphologies of calcium carbonate crystals nucleated on the self-assembled monolayer of L-cysteine. SEM images and XRD data demonstrated that the calcites from the(001) crystallographic plane are dominated. The structural match between the organic surfacethe (√3×√3)R30° structure] and that of the(001) crystal plane of calcite may account for the nucleation from these two planes. |
