Abstract

The nucleation in spherulitic crystallization from supercooled smectic phase to solid state for cholesteryl nonanoate was studied using classic transition-state theory of Turnbull and Fisher. In this paper we have used a unique method of the measurements and results interpretation instead of determining the nucleation rate. In the experiment, only the granularity and temperature were measured. It was found that the primary nuclei are 2D and the nucleation can be homogeneous or heterogeneous depending on the temperature range.
