Critical Micelle Concentrations in Surfactant Mixtures and Blends by Simulation [PDF]

open access: yesThe Journal of Physical Chemistry B, 2021
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]

open access: yesJournal of the Serbian Chemical Society, 2020
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.

Salinity Effect on the Surfactant Critical Micelle Concentration through Surface Tension Measurement [PDF]

open access: yesIranian Journal of Oil & Gas Science and Technology, 2019
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

open access: yes, 2010
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)

open access: yes, 2021
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 ...

Investigation on solution properties of surfactants in mixed solvent media: Landmark towards Surface Chemistry in Eastern Nepal

open access: yesBibechana, 2014
Surfactants are amphiphilic molecules having a hydrophilic or water soluble moiety (head group) and a hydrophobic, or water insoluble moiety (tail group).
