Surfactant-driven instability of a divergent flow
G. Koleski, J. -C. Loudet, A. Vilquin +2
Extremely small amounts of surface-active contaminants are known to drastically modify the hydrodynamic response of the water-air interface. Surfactant concentrations as low as a f…
Azimuthal instability of the radial thermocapillary flow around a hot bead trapped at the water-air interface
G. Koleski, A. Vilquin, J. -C. Loudet +2
We investigate the radial thermocapillary flow driven by a laser-heated microbead in partial wetting at the water-air interface. Particular attention is paid to the evolution of th…
Hydrodynamic response of a surfactant-laden interface to a radial flow
T. Bickel, J. -C. Loudet, G. Koleski +1
We study the features of a radial Stokes flow due to a submerged jet directed toward a liquid-air interface. The presence of surface-active impurities confers to the interface an i…
Stokes-Einstein diffusion of colloids in nematics
Frédéric Mondiot, Jean-Christophe Loudet, Olivier Mondain-Monval +3
We report the experimental observation of anisotropic diffusion of polystyrene particles immersed in a lyotropic liquid crystal with two different anchoring conditions. Diffusion i…
Dispersions of ellipsoidal particles in a nematic liquid crystal
Mykola Tasinkevych, Frederic Mondiot, Olivier Mondain-Monval +1
Colloidal particles dispersed in a partially ordered medium, such as a liquid crystal (LC) phase, disturb its alignment and are subject to elastic forces. These forces are long-ran…
Undulation instabilities in the meniscus of smectic membranes
J. C. Loudet, P. V. Dolganov, P. Patrício +2
Using optical microscopy, phase shifting interferometry and atomic force microscopy, we demonstrate the existence of undulated structures in the meniscus of ferroelectric smectic-C…
