“…At least two models can be discussed to describe density fluctuations along the flow direction. Figure illustrates these models: (i) a bending of the rod like micelles or (ii) a constricted or cut like micellar form. Fluctuations of the type (ii) might eventually lead to a transition to spherical micelles and were also discussed in the context of block copolymers. ,, We might note that the anisotropic SANS pattern of C 14 G(E 4 M) 2 at low q was best observed at low concentrations.…”

“…Measurements have also been made through the side of the cell, in the direction orthogonal to the shear gradient and in the flow direction. Recent experiments have demonstrated the importance of making measurements in this latter geometry for aligned lamellar phases Penfold, Staples, Lodi & Tucker, 1995). The Couette cell used here is of a design that, as recently demonstrated (Penfold, Staples, Lodi & Tucker, 1995), makes such measurements through the cell side feasible for neutron scattering by translating the Couette cell in a direction orthogonal to the beam (with a mean path length of 3 mm).…”

“…Due to the wide variety and subtlety in micellar phases, a larger number of shear-induced transitions have been observed in amphiphilic systems. These include the shear-induced alignment of rod-like micelles and the many associated complications (Penfold, Staples, Lodi & Tucker, 1995;Lin et al, 1996;Penfold, Staples & Cummins, 1991), isotropic to nematic/lamellar transitions (Berret, Roux, Porte & Lindner, 1994;Safinya, Sirota &Plano, 1991) and lamellar to multilamellar vesicle transitions (Penfold, Staples, Lodi & Tucker, 1995;Diat & Roux, 1993). In this paper, we present two different aspects of shear alignment and shear-induced transformations in lamellar phases of surfactants.…”
