    • 2, suggest that the morphology of DPS is described by an eight-sided plate, with the plate face assigned to (100). Plate edges are formed by the {011}, {111}, {002}, {110}, and {102} families of planes, but the {002}, {110}, and {002} planes are not observed experimentally.

    • note
    • Control studies using spreading solutions without surfactants (chloroform, chloroform with dichloroacetic acid, and hexanes) resulted in fast nucleation at the interface, producing a powder that typically lacked well-defined crystals and often appeared as an amorphous film. In contrast, spreading of hexadecane, which is significantly less volatile, inhibits nucleation at the interface. We ascribe the volatile-solvent-induced nucleation to concentrated interfacial cooling effects: lensing of solvent due to the absence of surfactant, coupled with fast evaporation, results in a lowering of the temperature at the interface, thus leading to rapid supersaturation and nucleation. Nucleation under ODS and stearic acid monolayers, while relatively fast, is typically slower than nucleation under the surfactant-free volatile solvents, most likely because the surfactants slow the solvent evaporation, allowing more time for the interfacial cooling to be dissipated.
