Thermodynamics of the Micellization of a Simple Zwitterionic Surfactant in the Presence of Imidazolium Salts [PDF]

ACS Omega
Although formally neutral, in aqueous media, zwitterionic micelles selectively concentrate the anions of added inorganic salts at the micelle-water interface. The resultant negative electrostatic potential of the micelles can be additionally modulated by

Influence of Valsartan on the thermodynamics of micellization of anionic surfactant Sodium Dodecyl Sulphate [PDF]

European Pharmaceutical Journal, 2016
In this manuscript was investigated behaviour of drug valsartan by micellar media of anionic surfactant sodium dodecyl sulphate. As the method was used electrical conductivity for the determination of critical micelle concentration at different ...

MOLECULAR THERMODYNAMICS OF MICELLIZATION: MICELLE SIZE DISTRIBUTIONS AND GEOMETRY TRANSITIONS [PDF]

Brazilian Journal of Chemical Engineering, 2016
Surfactants are amphiphilic molecules that can spontaneously self-assemble in solution, forming structures known as micelles. Variations in temperature, pH, and electrolyte concentration imply changes in the interactions between surfactants and micelle stability conditions, including micelle size distribution and micelle shape.

Thermodynamics of micellization of oppositely charged polymers [PDF]

Europhysics Letters (EPL), 2003
The complexation of oppositely charged colloidal objects is considered in this paper as a thermodynamic micellization process where each kind of object needs the others to micellize. This requirement gives rise to quantitatively different behaviors than the so-called mixed-micellization where each specie can micellize separately.

Thermodynamics of Micellization of Nonionic Surfactant Tween-40 in Presence of Additive Chloramine-T Using Clouding Phenomenon [PDF]

E-Journal of Chemistry, 2010
The phenomenon of solubilization of nonionic surfactant Tween-40 has been studied through the influence of additive chloramine-T in aqueous medium by measuring the cloud points (CP) of the pure surfactant and with chloramine-T.
