Active volatile drops on liquid baths
Benjamin Reichert, Jean-Benoît Le Cam, Arnaud Saint-Jalmes +1
In most experimental studies, active drops propel in a liquid bulk due to self-generated interfacial stresses of solutal origin. Here, we demonstrate the self-propulsion of a volat…
The Marangoni flow of soluble amphiphiles
Matthieu Roché, Zhenzhen Li, Ian M. Griffiths +4
Surfactant distribution heterogeneities at a fluid/fluid interface trigger the Marangoni effect, i.e. a bulk flow due to a surface tension gradient. The influence of surfactant sol…
Switching Reversibly between Ultrastable and Unstable Foams
Anne-Laure Fameau, Arnaud Saint-Jalmes, Fabrice Cousin +7
Ultrastable foams with an optimal foamability have been obtained using hydroxyl fatty acids tubes. The stabilization results from the adsorption of monomers at the air-water interf…
Surfactant-assisted spreading of an oil-in-water emulsion on the surface of a liquid bath
Matthieu Roche, Zhenzhen Li, Ian Griffiths +2
This fluid dynamics video shows how an oil-in-water emulsion stabilized by an ionic surfactant spreads on the free surface of a layer of pure water. The spreading shows two intrigu…
