My research interest is about the mechanism of glass crystal (GC) growth. Crystal growth is controlled by diffusion in highly supercooled liquid. Yet for some systems, when cooled to near glass transition temperature, there is an increase of crystal growth by decades relative to diffusion-controlled growth. This fast crystal growth is of importance to amorphous formulation in pharmaceutics which must resist crystallization during shelf life. One of the most recent and promising explanations is that GC growth is facilitated by continuously creating free surface near growth front and the free surface can provide enough mobility for crystal growth. My work is to test this theory of GC growth and study confinement effects on surface crystal growth.
