Abstract

The formation of a so‐called water/oil (W/O)‐microemulsion (AOT/isooctane/water) was followed by light scattering and ultracentrifuge measurements. With increasing weighed‐in water concentrations the microemulsion is stabilized by repeated aggregational processes of micelles containing water due to a decrease of the free interfacial enthalpy.

This process conforms very satisfactorily to a model describing an adsorption of surfactants at the water/hydrocarbon interface resulting from dipole‐image dipole interactions.

In this study the formation of approximately spherical assemblies of nanocrystalline primary particles of CdS in a CS 2 -waterethylenediamine (CWE) microemulsion induced by ultrasonic irradiation is described. CS 2 was employed as the sulfur source for CdS and also as the oil phase in the microemuls
