Dynamical rheology of a lyotropic lamellar phase near an out-of-equilibrium transition
This work deals with sustained oscillations of a complex fluid near a shear-induced transition. Rheological measurements of the onion texture near a layering transition are performed in a Couette cell. This co...

Dilute and concentrated phases of vesicles at thermal equilibrium. Effect of bilayer elasticity
It has been shown theoretically that phases of unilamellar and multilamellar vesicles are stable when the curvature energy of the bilayer, described by two elastic constants κ and

Surfactant Association: Recent Theoretical and Experimental Developments
A theoretical model describing the association of ionic surfactants into rod-shaped micelles is combined with an approximate formula for the viscosity increase induced by rod-shaped aggregates. It is shown tha...

Universal Behavior in Phospholipid Multimembrane Systems
Stacked multimembrane structures of the phospholipid DMPC show two interesting universal behaviors due to geometric concerns. X-ray scattering studies were done to elucidate the structure of the ordered phases...

Field Variables and Critical Phenomena in Microemulsions
Some general features of field variables and critical phenomena in multicomponent systems are discussed. Critical behavior of surfactants in solution is specially examined, and results for a ternary system com...

Experimental evidence for bicontinuous structures in L 3 phases
Anomalous flow birefringent phases, sometimes designated as L 3, have been identified in both the water-rich and the oil-rich parts of the phase diagram of the water(-NaCl)-dodecane-pentanol-SDS sys...

Dynamiclight scattering study of membrane interactions in colloidal smectics
Dynamic light scattering measurements on oriented samples of dilute lyotropic smectics have been performed. The hydrodynamics of a two-component smectic A is reviewed and applied to describe the fluctuation spect...

Thermal Fluctuations and the Structure of Microemulsions
We analyze the role of thermal fluctuations in determining the phase equilibria and structural properties of microemulsions. In the dilute limit, where the microemulsions are globular, the effects of thermal f...

Critical Behavior in a Microemulsion System. II — Experimental Evidence for a Continuous Variation of Critical Exponents
We present light scattering results obtained for a four-component microemulsion system in several distinct positions of a critical line. This line starts at a critical end point. The critical points were appro...

Critical Behavior in a Microemulsion System: I — Experimental Evidence for Field Like Variable
Phase diagram analysis and light scattering results of quaternary and ternary mixtures provide evidence for the existence in the oil rich region of an apparent field variable related to composition: the water ...

Effect of the molecular structure of components on micellar interactions in microemulsions
The effect of the chemical nature of oil, alcohol and surfactant on interactions in W/O microemulsions has been studied by light scattering and photon correlation spectroscopy. The influence of the chain lengt...
