DOI: 10.1039/c7sm00090a
Abstract: We compute the effective viscosity of particulate soap films thanks to local velocity fields obtained by Particle Image Velocimetry (PIV) during film retraction experiments. We identify the jamming of these 2D capillary suspensions at a… read more here.

DOI: 10.1063/1.4986003
Abstract: In this short review, I focus on recent experiments that benefit from the advantages offered by the two-dimensionality of the flow in suspended thin liquid films to reconsider hydrodynamics problems which have resisted a full… read more here.

DOI: 10.1103/gfxm-67mm
Abstract: Liquid foams exhibit menisci whose lengths range from hundreds of microns in microfoams to several centimeters in macroscopic bubble arrangements. These menisci are known to thin under gravity until reaching a steady thickness profile, where… read more here.

DOI: 10.1103/physrevlett.134.168201
Abstract: The effective viscosity of liquid foams is controlled by Marangoni forces and therefore by the transport of surfactants. Direct tracking of the latter during foam deformation is out of reach. Besides, the competition between diffusion… read more here.

DOI: 10.1119/5.0275602
Abstract: The subject of soap films and their color is revisited. Following an educational path through wave optics, an account is provided for the color pattern of the films as related to the film thickness, spectral… read more here.
