Sphere-to-cylinder transition in aqueous micellar solution of a dimeric (gemini) surfactant
Article Abstract:
A new study shows that micelle growth in solutions of the dimeric surfactant 12-2-12(dimethylene-1,2-bis(dodecyl dimethylammonium bromide)) conforms to previous models.

Microstructures in aqueous solutions of mixed dimeric surfactants: Vesicle transformation into networks of thread-like micelles
Article Abstract:
An attempt was made to investigate the microstructures in mixtures of two dimeric (gemini) surfactants, the dimethylene-1,2-and eicosamethylene-1,20-bis(dimethyldodecylammonium bromide) at 25 degree Celsius by electrical conductivity, spectrophotometry, digital light microscopy (DLM), and transmission electron microscopy at cryogenic temperature (cryo-TEM). The cryo-TEM observations were performed on samples vitrified two months after preparing the mixtures.

A cloud point study on the micellar growth of an amphiphilic drug in the presence of alcohol and ionic surfactant
Article Abstract:
Cloud point (CP) measurements to study the effect of alcohols on the micellar growth of amphiphilic drug amitriptyline (AMT) in the presence of salt (sodium phosphate) and surfactants (sodium dodecyl sulfate, cetylpyridinium chloride) are carried out. The measurements revealed that the CP monotonically increased with increasing shorter-chain alcohol (C4OH or C5OH) concentration because of the negligible partitioning of alcohol concentration because of the negligible partitioning of alcohol in AMT micelles.
