Ultrasound transmission through monodisperse 2D microfoams
Lorène Champougny, Juliette Pierre, Antoine Devulder +2
While the acoustic properties of solid foams have been abundantly characterized, sound propagation in liquid foams remains poorly understood. Recent studies have investigated the t…
Influence of evaporation on soap film rupture
Lorène Champougny, Robin Henaff, Frédéric Restagno +2
Although soap films are prone to evaporate due to their large surface to volume ratio, the effect of evaporation on macroscopic film features has often been disregarded in the lite…
Life and death of not so "bare" bubbles
Lorène Champougny, Matthieu Roché, Wiebke Drenckhan +1
In this paper, we investigate how the drainage and rupture of surfactant-stabilised bubbles floating at the surface of a liquid pool depend on the concentration of surface-active m…
The break-up of free films pulled out of a pure liquid bath
Lorène Champougny, Emmanuelle Rio, Frédéric Restagno +1
In this paper, we derive a lubrication model to describe the non-stationary free liquid film that is created when a vertical frame is pulled out of a liquid reservoir at a given ve…
Surfactant-induced rigidity of interfaces: a unified approach to free and dip-coated films
Lorène Champougny, Benoit Scheid, Frédéric Restagno +2
The behavior of thin liquid films is known to be strongly affected by the presence of surfactants at the interfaces. The detailed mechanism by which the latter enhance film stabili…
