Crystallographic registry

Webnucleation is shown to depend strongly on crystallographic registry between the nucleating agent and the critical nucleus, indicative of an epitaxial mechanism in this class of materials. Importantly, the severity of this registry requirement weakens with decreasing rigidity of the substrate and increasing strength of attraction to the nucleating WebIn general, the misorientation angles between the crystallographic planes across the ordinary GBs described in the previous section are randomly distributed, and atomic …

WebAug 8, 2024 · In crystallization, either from solution or from a melt, homogeneous nucleation is a statistical process. 29 - 31 The resulting crystals are distributed randomly all over the sample, without any correlations between these crystals. 1, 11, 18 Therefore, in order to understand how stacks of correlated lamellar crystals are generated, we need to … WebAbstract. Our simulations of polymer crystallization from solutions show that (1) entropic barriers control the selection of the initial lamellar thickness, (2) growth at the crystalline interface is chain adsorption followed by crystallographic registry, and (3) lamellar thickening is a highly cooperative process requiring the mobility of all chains in the crystal. how to resolve system slowness issue
