Blastulae aggregates: New intermediate structures in the micelle-to-vesicle transition of catanionic systems

Abstract

A new type of intermediate structure was found in the salt-induced micelle-to-vesicle transition in a catanionic system composed of Na dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide (DTAB) in aq. soln. with an excess of anionic surfactant. The appearance of sym. shaped hollow structures, which the authors named blastulae vesicles, is presented.
