International audience; The spreading of a liquid over a solid material is a key process in a wide range of applications. While this phenomenon is well understood when the solid is undeformable, its ''soft'' counterpart is still misunderstood and no

International audience; We report on the contact line dynamics of a triple-phase system silica/oil/water. When oil advances onto silica within a water film squeezed between oil and silica, a rim forms in water and recedes at constant velocity. We evi

Most studies of dewetting fronts in 3D with a “corner formation”, as happens behind a drop sliding down an incline are based on a generalisation of Voinov theory, with (at least implicitly) a slip length at small scale. I here first examine what

International audience; We study the contact line dynamics of a liquid drop on a substrate at temperature Ts colder than the freezing temperature Tm. The purpose is to determine experimentally the criterion for a solidification-induced pinning of the

We investigate here the static finite deformation of two (or more) three-dimensional nonlinear elastic solids which merge in a third medium, defining a triple line ( tl ). The total energy, accounting for elastic, surface and possible gravity potenti
