Light scattering measurement and Avrami analysis of the lamellar to inverse hexagonal phase transition kinetics of the lipid DEPE.

The lamellar to inverse hexagonal phase transition of lipids is much studied as a model for understanding cellular processes such as membrane fusion and pore formation. Much remains unknown, including a theoretical understanding and a definitive value of the phase transition temperature for DEPE, as literature values vary over 10°C. Avrami theory has been commonly used to analyze phase transition kinetics.
