    Confined diffusion of hydrophilic probes inserted in lyotropic lamellar phases

    The dynamic behaviour of three hydrophilic probes (two dyes and one fluorescently-labelled protein) inserted in the water layers of lyotropic lamellar phases has been studied by confocal fluorescence recovery ...

    Specific Features of Nanoscale Growth

    It is no easy matter to make nanoscopic objects. In fact, starting from a macroscopic sample, as one does when making objects with centimeter or millimeter dimensions, one soon comes up against technical probl...

    Biology and the Environment

    Since the 1980s, catalytic antipollution systems for petrol-fuelled vehicles have considerably reduced emissions of CO, NO x , and unburnt hydrocarbons. They use precious metals as c...

    Role of dislocation loops on the elastic constants of lyotropic lamellar phases

    We study the role of dislocation loops defects on the elasticity of lamellar phases by investigating the variation of the lamellar elastic constants, ¯ and K, induced by the proliferation of these defects. We foc...

    Incorporating DNA in a lamellar phase: A Flory model

    Following an experimental work demonstrating that DNA pieces can be incorporated in large quantity in a neutral lamellar phase, we propose a theoretical model showing that finite-size rod-like particles can be...

    Anomalous elasticity of an ordered lamellar liquid foam

    We investigate experimentally the linear viscoelastic properties of a lamellar liquid foam as a function of the cell size and spatial organisation. The system consists of multilamellar vesicles generated by a ...

    Swelling kinetics of a compressed lamellar phase

    We investigate how multilamellar vesicles prepared in a compressed state under flow return to equilibrium. The kinetics is studied by following the temporal evolution of the viscoelasticity after the shear is ...

    Lamellar-to-nematic phase transition in a lipid-surfactant mixture

    A lyotropic system, consisting of a lecithin (DMPC) and a non-ionic surfactant (C12E5) in water was studied. The system exhibits a lamellar-to-nematic phase transition. The nematic phase appears as the temperatur...

    Undulation instability under shear: A model to explain the different orientations of a lamellar phase under shear?

    We study the effects of a dilation on a sheared smectic A phase. Through a linear analysis, we show that undulation may grow in the direction of the flow and of the vorticity as found in previous works. At hig...
