Phys., Paris, 48, 673, This situation, observed with concentrated lamellar phases, should not be confused with that encountered with swollen lamellar phases, diluted with oil or water, where diffuse scatterings around the Bragg reflections indicate intense fluctuations of the lamellar order corresponding to large undulation modes of the films of amphiphiles without perturbation of their structure

Lett., Paris, 46, 27, Indeed, in previous studies of this system, we had observed that aggregates with strongly inhomogeneous interfacial curvature are often present in its isotropic, nematic and rectangular phases and that the modulations of interfacial curvatures are related with inhomogeneous distributions of sodium decyl sulphate and decanol molecules

- It could also be argued that this substitutional disorder originates from the inverted situation, where water lamellae might be perturbed by amphiphilic molecules connecting two amphiphilic lamellae through one water lamella. However, as the phases observed for very high soap/decanol ratio are ordered two-dimensional rectangular and hexagonal phases with amphiphilic aggregates dispersed in a continuous water medium [9], we dismiss this situation
