Hierarchical Structure of Glucosamine Hydrochloride Crystals in Antisolvent Crystallization

Crystals, 2023
The crystal morphology of glucosamine hydrochloride (GAH) during antisolvent crystallization was investigated in this work. Particles of different shapes, such as plate-like crystals, leaflike clusters, fan-like dendrites, flower-like aggregates, and ...

Crystallization and crystal morphology of polymers: A multiphase-field study. [PDF]

J Thermoplast Compos Mater
In this paper, we introduce a coarse-grained model of polymer crystallization using a multiphase-field approach. The model combines a multiphase-field method, Nakamura’s kinetic equation, and the equation of heat conduction for studying microstructural evolution of crystallization under isothermal and non-isothermal conditions.

Detection and characterization of folded-chain clusters in the structured melt of isotactic polypropylene

IUCrJ, 2021
Despite ceaseless efforts in past decades, the memory effect of semi-crystalline polymers has not been elucidated completely yet. An important reason why is that residual lamellar crystals in the structured melt are difficult to characterize.
