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 few thousand molecules per square micron are sufficient to eventually i

WOS:000401378800010; International audience; The two-beam levitator (TBL) is a standard optical setup made of a couple of counter-propagating beams. Note worthily, TBLs allow the manipulation and trapping of particles at long working distances. While

International audience; 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 in-plane elasticity that resists the incident f

The existence of a new regime in convective instabilities when the wavelength of the instability becomes smaller than the pore size is demonstrated. A theory, adapted from classical linear stability analyses, accompanies experimental characterization

Dielectric ellipsoids have been observed to undergo sustained oscillations driven by laser radiation pressure forces and torques. We show, both experimentally and numerically, that these oscillations can be suppressed using 2-counter-propagating beam

"Shear-induced segregation" (SIS) means that different species of particles in a granular material or a concentrated suspension tend to unmix under flow. In principle, any kind of difference (size, density, shape and even surface state) may lead to S
