Molecular mecanisms of friction at soft polymer interfaces
Different experiments show a correlation between interaction heterogeneities (roughnessor chemical inhomogeneities) and friction properties of surfaces but the exact... -
Non-Newtonian thin films with normal stresses: dynamics and spreading.
The dynamics of thin films on a horizontal solid substrate is investigated in the case of non-Newtonian fluids exhibiting normal stress differences, the rheology of... -
Localization of a polymer interacting with an interface.
We study different models of polymers (discrete and continuous) in the neighborhood of an interface between two solvents<br />(oil-water). These models give rise... -

Wetting of soluble polymers
The wetting of a soluble substrate is a situation commonly encountered in day-to-day life. For instance, the practical motivation of this study concerns the... -

Surface patterning and integration of colloids by directed assembly
We present here a surface patterning process based on the directed assembly of colloids in a suspension. The technique uses a suspension drop which is dragged along a... -

Flow with wetting effects:<br />Drops and meanders on an inclined plane
Under partially wetting conditions, the rear of drops sliding down an inclined plane develops, above a critical velocity, a cornered singularity which is rounded at... -

Plants, drops, jets and grains: a few problems at liquid or elastic interfaces.
Dans ce manuscrit, je présente différents problèmes faisant intervenir des interfaces déformables. Ces interfaces peuvent être liquides (gouttes, jets, bulles) mais... -

Mobile interfaces: non-wetting drop friction and front dynamics
Through several experiments, we investigate situations for which interfaces play a major role on the dynamics of either drops or liquid fronts. First, we study several... -
Propulsion and friction of non-wetting objects
We investigate special dynamics generated by non wetting objects. On a substrate textured with asymmetric sawtooth-like grooves, a Leidenfrost liquid or solid is... -
