From industrial to biophysical situations, interfaces have a significant impact on the properties of multiphasic systems. In this seminar, I will present two examples of recent work showing that interfaces can be controlled using mechanical effects.
The first part of this seminar will focus on the wetting of fibers by a liquid and demonstrate the influence of important physical parameters on the resulting morphology of the liquid. In particular, we will show that the possibility to tune the morphology has important implications for drying processes in fibrous media. In the second part of the talk we will try to answer to the following question: why does coffee spill more easily than beer? Our study indicates that the addition of foam at an air/liquid interface can be used to passively damp the sloshing, i.e. the oscillation of the interface, and to avoid the spilling of the liquid.
