Turbidimetric evaluation of the solubilization rate: dissolution of dodecane nanodrops in 7.5 mM sodium dodecylsulfate solutions at selected sodium chloride concentrations
Jose Daniel Rodriguez, Maurice Espinoza, Kareem Rahn-Chique +1
The rate of micelle solubilization (SR) can be appraised following the decrease of the radius of a macroscopic drop of oil in contact with a surfactant solution [Todorov, 2002]. Al…
Electric surface potential of dodecane nano-drops in aqueous solutions of low ioinic strength
Daniela Diaz, Kareem Rahn-Chique, German Urbina-Villalba
While the surface charge of solid particles is a direct consequence of their synthesis, the one of suspended oil drops depends on the adsorption equilibrium of the surrounding mole…
Influence of surfactant crystallization on the aggregation rate of dodecane-in-water nanoemulsions. Changes in the viscosity of the external phase
Daniela Diaz, Kareem Rahn-Chique, Neyda Garcia-Valera +1
Rates of aggregation of dodecane-in-water (d/w) nanoemulsions stabilized with 7.5 mM sodium dodecylsulfate (SDS) are evaluated beyond 500 mM NaCl. As in the case of hexadecane-in-w…
Nanoemulsion stability above the critical micelle concentration: A contest between solubilization, flocculation and Krafft precipitation
Kareem Rahn-Chique, Oriana Barrientos, German Urbina-Villalba
The relative importance of micelle solubilization and Krafft temperature on the appraisal of the flocculation rate is studied using a dodecane-in-water nanoemulsion as a model syst…
Use of the theory of Lifshitz-Slyosov-Wagner for the evaluation of the aqueous solubility of dodecane
Loredana Espinoza, Kareem Rahn-Chique, Issarly Rivas +1
The solubility of dodecane was determined using the theory of Lifshitz-Slyosov-Wagner for the Ostwald ripening phenomenon. For this purpose, a set of dodecane in water nanoemulsion…
Theoretical Prediction and experimental measurement of the mixed flocculation/coalescence rate of ionic Hexadecane-in-water nano-emulsions
German Urbina-Villalba, Neyda Garcia-Valera, Kareem Rahn-Chique
Theoretical calculations of the mixed aggregation/coalescence (kFC) rate corresponding to a set of hexadecane-in-water nano-emulsions stabilized with sodium dodecyl sulphate (SDS)…
Correct Use of the Lifshitz-Slyosov-Wagner Expression for the Calculation of the Average Radius of an Oil-In-Water (o/w) Emulsion Subject to Coalescence
Kareem Rahn-Chique, German Urbina-Villalba
The analytic expression proposed by Lifshitz-Slyozov and Wagner (LSW theory) for the linear variation of the cube average radius (R3) of an emulsion as function of time (t) is comm…
Phase Behavior and Emulsion Stability of the Aot/Decane/ Water/NaCl System at Very Low Volume Fractions of Oil
Yithanllili Bastidas, Lisset Hernaandez, Issarly Rivas +2
The stability of a ternary system composed of decane/water/Aerosol-OT and salt is revisited. Phase diagrams and emulsions similar in composition to those previously studied by Hofm…
Influence of ripening and creaming on the aggregation rate of dodecane-in-water nanoemulsions. Is the creaming rate an appropriate measure of emulsion stability?
Yorlis Mendoza, Kareem Rahn-Chique, Antonio M. Puertas +2
The behavior of four oil-in-water (O/W) ioinic nanoemulsions composed of dodecane, and mixtures of dodecane with squalene and tetra-chloro-ethylene is studied. These nanoemulsions…
Short-time Evolution of Alkane-in-Water Nanoemulsions
German Urbina-Villalba, Kareem Rahn-Chique
The stability of alkane-in-water nanoemulsions during the sub-stationary regime is studied by means of Emulsion Stability Simulations (ESS). The effects of Ostwald ripening, floccu…
Nanoemulsion stability: experimental evaluation of the flocculation rate from turbidity measurements
Kareem Rahn-Chique, Antonio M. Puertas, Manuel S. Romero-Cano +2
The coalescence of liquid drops induces a higher level of complexity compared to the classical studies about the aggregation of solid spheres. Yet, it is commonly believed that mos…
