Nano-niosomes as nanoscale drug delivery systems: An illustrated review

Surfactants form a unique class of chemical compounds. This review provides an introduction to the nature and physical properties of surfactants, emphasizing their ability to radically alter surface and interfacial properties and to self-associate and solubilize themselves in micelles. These properties provide the means to apply surfactants in wettability modification, detergency, and the displacement of liquid phases through porous media on one hand, and to stabilize dispersions (including foams, froths and emulsions), or to destabilize dispersions (again including foams and emulsions) on the other hand. These in turn lead to a vast array of practical application areas which are illustrated in terms of mineral and petroleum processing, biological systems, health and personal care products, foods, and crop protection.

The influence of interfacial tension in the recovery of bitumen by water-based conditioning and flotation of Athabasca oil sands

The critical micelle concentrations (CMCs) were determined for five commercial surfactants in two brines of different hardness but equal ionic strength These included a carboxyl-betaine, a sulfo-betaine, a mixture of anionics, and its two individual components CMCs were measured by three techniques: (i) surface tensions by Wilhelmy plate at ambient pressure, from 2 to 30°C, (ii) surface tensions by captive drop, at 138 MPa applied pressure, from 25 to 180°C, and (iii) dynamic foam height measurements at 138 MPa (applied) from 23 to 180°C The CMCs were found to decrease to a minimum with increasing temperature and then sharply increase, most markedly over 100°C This behavior is explained in terms of hydrophobic forces, described in terms of calculated thermodynamic parameters using the phase separation model, and forms the basis for a predictive model of the temperature dependence of the CMC using the reduced-variables approach
