Crystallization from the melt or gas is one of the most popular and well-known phenomena in any materials. Nucleation which is the early process of crystallization controls significantly structure and physical properties. Although classical nucleation theory (CNT) assumed theoretically the nucleation in the 1930s, nobody could succeed in confirming the nucleation because of technical difficulties.
We succeeded in experimental confirmation of nucleation of nano-nuclei of polyethylene (PE) for the first time by means of small angle X-ray scattering (SAXS).
