WebJan 21, 2024 · Nucleation Abstract Crystallization is the process of atoms or molecules forming an organized solid via nucleation and growth. Being intrinsically stochastic, the research at an atomistic level has been a huge experimental challenge. WebJan 12, 2015 · The conventional view of nucleation, a seeding step that ultimately determines several properties of the crystal formed, is that it proceeds through a classical pathway. In this model, ions or molecules come together into an embryonic cluster that is ordered in the same way as the eventual crystal.
WebMany pathways to crystals have been observed in a range of systems that seemingly deviate from the single-step crystal nucleation mechanism from a parent solution phase that is predicted by classical nucleation theory (CNT). 1,2 It was shown some time ago in simulations of spherical particles with short-ranged interactions that, under appropriate …
