| Research Abstract |
Owing to the self-organized viscoelastic field, softmaterials crystallize under conditions far from equilibrium, which leads to the evolution of various spatio-temporal patterns. On the basis of the recent developments in the field of non-linear and non-equilibrium dynamics, we examined the crystallization process of crystalline aggregates of such as semi-crystalline polymers, organic molecules, and proteins. In this project, the meaning and the role of the following processes and phenomena in the crystallization were clarified : morphological instability at the growth front, spatio-temporal patterns of branching and re-orientation of crystallites, confined geometry set by nm-size thickness in ultra-thin film, molecular diffusion dynamics at the growth front, self-excited oscillation of crystal orientation and growth rate.
