Polymorphic selectivity in crystal nucleation
WebApr 14, 2024 · Polymorphic selectivity in crystal nucleation. Crystal nucleation rates have been measured in the supercooled melts of two richly polymorphic glass-forming liquids: … WebNov 16, 2024 · We have measured the crystal nucleation rates at the surface and in the bulk of amorphous poscaconazole, a rod-like molecule known to have a preferred interfacial orientation. We find that surface nucleation is vastly enhanced over bulk nucleation, by ∼9 orders of magnitude, and selects a different polymorph (II) from bulk nucleation (I).
