Optical micrographs of mesophase samples during mixing. (a) Non-uniform mixtures of cubic (light) and lamellar (dark) mesophases at ambient temperature. (b) Fully mixed mesophases after several freeze-thaw-mix cycles; the dark color indicates a predominantly lamellar state in all mixers. (c) Samples from (b) after 30 min at 23 °C. Changes in the appearance of the samples indicate a phase transition from a lamellar phase to cubic phases. (d) Same as panel (c), under cross-polarized light. Numbers indicate initial βOG concentrations in aqueous compartments and are the same for all panels. Scale bar: 1 mm.
