Dataset description

Dataset supporting a study of the pseudomorphic transformation of amorphous calcium carbonate (ACC). We demonstrate a straightforward method for controlling the crystallization of ACC thin films in which nucleation is first triggered using a heated probe, and growth is then sustained by incubating the film at a lower temperature. By independently controlling nucleation and growth we can readily generate sub-millimeter scale calcite single crystals when and where desired, create morphologies ranging from discs, to squares to serpentine strips, and generate arrays of crystals. We can also study the mechanism and energetics of crystallization of the ACC using in situ TEM and demonstrate continuity between the ACC and calcite at the growth front.
