Locating the micellar shear plane and its relationship with the Debye screening length

Article Abstract:

Adequate information on micelles and colloids as important parameters in the study of charged surfaces of suspended particles are relatively scarce and a majority of available related research are confined to colloidal and polymeric particles. To augment this dearth of information, a study has been conducted involving the use of the rotating disk electrode to determine micellar hydrodynamic radii as a function of electrolyte concentration for cetyltrimethylammonium chloride micelles. Findings have indicated that estimations of the Debye screening length at the micellar charged surface allow direct comparison with the shear plane thickness.

Effect of CO2 on the properties of AOT/water/isooctane reverse micelles by fluorescence study

Article Abstract:

The effect of compressed CO2 on the properties of sodium bis (2-ethylhexyl) sulfosuccinate/water/isooctane reverse micelles was analyzed by steady-state and time-resolved fluorescence spectroscopic techniques. The study reveals the steady-state fluorescence spectroscopy with prodan as the sovachromic probe shows that compressed CO2 results in an increase in micropolarity of water inside the reverse micelles.

Simultaneous observation of attractive interaction, depletion forces, and "sticky" encounters between AOT reverse micelles in isooctane using microelectrode voltammetry

Article Abstract:

Steady-state microelectrode voltammetry has shown to be a simple and useful tool for studying various interaction processes in reverse micellar systems. The fact that voltammetry is precise, inexpensive, and rapid suggests that this tool may become important in the study of reverse micelles systems, in particular the time-dependent evolution of supramolecular structure and interaction processes.
