Polymorphic selectivity in crystal nucleation
WebApr 14, 2024 · Probability and anity for nucleation and subsequent growth are higher on or adjacent to the newly formed crystals than the foreign substrate surface [1, 2]. Detailed high-resolution scanning electron microscopy (SEM) with secondary electrons (SE) together with energy-dispersive X-ray spectroscopy (EDS) provided direct evidence of this selective ... WebOct 6, 2024 · For organic crystals, the solvent composition also determines the selective nucleation of polymorphic forms . For oriented attachment processes, the solvent modulates interactions with organic ligands and also provides a certain degree of particle movement that enables co-orientation and coalescence [31,51,52,53,54].
