Critical Micelle Concentrations in Surfactant Mixtures and Blends by Simulation [PDF]
We explore the use of coarse-grained dissipative particle dynamics simulations to predict critical micelle concentrations (CMCs) in polydisperse surfactant mixtures and blends. By fitting pseudo-phase separation models (PSMs) to aqueous solutions of binary surfactant mixtures at selected compositions above the CMC, we avoid the need for expensive ...

Hysteresis of conductivity in a micellar surfactant solution near the Krafft point [PDF]
The specific conductivity of aqueous cetyltrimethylammonium bromide solutions has been investigated below and above the critical micelle concentration, in order to elucidate slow structural changes.

Self-consistent-field calculations of proteinlike incorporations in polyelectrolyte complex micelles [PDF]
Self-consistent field theory is applied to model the structure and stability of polyelectrolyte complex micelles with incorporated protein (molten globule) molecules in the core.

Self-assembly of triblock copolymers in aqueous solution [PDF]
Indexación: ScieloThe aggregation of PE4VP-b-PS-b-PE4VP block copolymers was studied in aqueous solution. Triblock copolymers P4VP-b-PS-b-P4VP were synthesized by sequential anionic polymerization of poly(styrene) and poly(4-vinylpirydine) using sodium ...

Salinity Effect on the Surfactant Critical Micelle Concentration through Surface Tension Measurement [PDF]
One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals.

Kinetics of Surfactant Micellization: a Free Energy Approach
We present a new theoretical approach to the kinetics of micelle formation in surfactant solutions, in which the various stages of aggregation are treated as constrained paths on a single free-energy landscape.

Measurement of Critical Micelle Concentration (CMC)
The Critical Micelle Concentration (CMC) is the surfactant concentration above which the addition of a monomer leads to the formation of the first micelle. Above the CMC, monomers and micelles exist in dynamic equilibrium. Almost all physical properties of a surfactant solution exhibit a sharp concentration dependent discontinuity in the region of ...
