Foams are unstable jammed materials. They evolve over timescales comparable to their “time of use”, which makes the study of their destabilisation mechanisms crucial for applications. In practice, many foams …

Evaporation is known to cause cooling, much like perspiration. Physicists have measured the temperature of soap films to show that they can be up to 8°C cooler than the temperature of the environment.
Hydrodynamic flows in compliant channels are of great interest in physiology and microfluidics. In these situations, elastohydrodynamic coupling leads to (i) a nonlinear pressure-vs-flow-rate relation, strongly affecting the hydraulic resistance; and …
We study in this article, published in Soft Matter, the debonding of a soft adhesive layer from a micrometric pillar. We uncover power laws as a function of the pillar …
We have recently published this article in which we demonstrate that the surfactant concentration is important for bubble stability, as expected but that the reason why is that it affects …
Authors: François Boulogne, Alexis Commereuc When glass tubes are plunged in a glass filled with a foamy liquid which is covered by a foam layer, bubbles spontaneously enter in the …
We investigate theoretically and numerically the diffusion-limited evaporation of a liquid deposited on a fiber in two configurations: a sleeve and a axisymmetric barrel-shaped droplet. For a sleeve, the local …
Manon Marchand defended her PhD thesis at Laboratoire de Physique des Solides on the foam friction on rough surfaces. She obtained the price from the physics graduate school of Paris-Saclay …
We just published an article in Phys. Rev. Fluids on the drainage of surface bubbles. The prediction of the lifetime of surface bubbles indeed necessitates a better understanding of the …
