Analytical modeling of micelle growth. 4. Molecular thermodynamics of wormlike micelles from ionic surfactants: theory vs. experiment
K. D. Danov, P. A. Kralchevsky, R. D. Stanimirova +3
Hypotheses: The aggregation number and length of spherocylindrical (rodlike, wormlike) micelles in solutions of an ionic surfactant and salt can be predicted knowing the molecular…
Nonequilibrium continuous phase transition in colloidal gelation with short-range attraction
Joep Rouwhorst, Christopher Ness, Simeon Stoyanov +2
The dynamical arrest of attractive colloidal particles into out-of-equilibrium structures, known as gelation, is central to biophysics, materials science, nanotechnology, and food…
Analytical modeling of micelle growth. 3. Electrostatic free energy of ionic wormlike micelles -- effects of activity coefficients and spatially confined electric double layers
K. D. Danov, P. A. Kralchevsky, S. D. Stoyanov +2
Hypotheses: To correctly predict the aggregation number and size of wormlike micelles from ionic surfactants, the molecular-thermodynamic theory has to calculate the free energy pe…
Origin of the extremely high elasticity of bulk emulsions, stabilized by Yucca Schidigera saponins
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +4
We found experimentally that the elasticity of sunflower oil-in-water emulsions (SFO-in-W) stabilized by Yucca Schidigera Roezl saponin extract, is by more than 50 times higher as…
Role of interfacial elasticity for the rheological properties of saponin-stabilized emulsions
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +3
Hypothesis Saponins are natural surfactants which can provide highly viscoelastic interfaces. This property can be used to quantify precisely the effect of interfacial dilatational…
Foamability of aqueous solutions: Role of surfactant type and concentration
B. Petkova, S. Tcholakova, M. Chenkova +4
In this paper we study the main surface characteristics which control the foamability of solutions of various surfactants. Experiments with anionic, cationic and nonionic surfactan…
