Stabilising Evaporating Soap Films with Salt
Victor Ziapkoff, François Boulogne, Anniina Salonen +1
We investigate the effect of a high concentration (32.5 g.L) of sodium chloride (NaCl) on TTAB (tetradecyltrimethylammonium bromide) vertical soap films also called foam fil…
White light interferometry analysis for measuring thin film thickness down to few nanometers
Victor Ziapkoff, François Boulogne, Anniina Salonen +1
We present a practical white-light interferometric method, supported by an open-source Python library \textit{optifik} for automated spectrum-to-thickness deduction, enabling foam…
Role of evaporation in stability of foam films and foams
F. Boulogne, E. Rio
Understanding the stability of foam films and foams remains a challenge, despite the considerable efforts provided by the scientific community to refine their physical descriptions…
Crystal growth at a liquid-liquid interface upon drop impact
Marion Berry, Christophe Josserand, Anniina Salonen +1
The crystallisation that occurs when a drop is placed in contact with a cold surface is a particularly challenging phenomenon to capture experimentally and describe theoretically.…
Reducing Foam Friction with Self Slippery Liquid-Infused Porous Surfaces
Alexis Commereuc, Emmanuelle Rio, François Boulogne
Acquiring a comprehensive understanding of the interplay between foam friction and surface roughness is essential for achieving precise control over their flow dynamics. In particu…
Self-assembly and non-equilibrium phase coexistence in a binary granular mixture
A. Plati, R. Maire, F. Boulogne +3
We report the experimental observation of a square crystalline phase in a vibrated binary mixture of spherical grains. This structure spontaneously forms from a disordered state, c…
