摘要
A unique reversible transformation between toroidal and cylindrical assemblies was observed. Toroids can change to cylinders by elongation at higher temperature. Reversely, upon cooling rate these cylinders can form toroids through pathway of cylinder-sphere-vesicle-ring or the end-to-end connection.
