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…
Air entrainment by an inclined smooth water jet
Théophile Gaichies, Arnaud Antkowiak, Anniina Salonen +1
Air entrainment can occur when a water jet impacts a water/air interface, a process central in various real systems, ranging from dam spills to breaking waves. Despite its prevalen…
Shape of an interface hit by an oblique jet
Theophile Gaichies, Anniina Salonen, Arnaud Antkowiak +1
We report on the shape taken by the interface of a liquid bath when hit by a smooth oblique steady jet. When the angle between the jet and the bath decreases below , a ca…
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…
Rheological response of soft Solid/Liquid Composites
Elina Gilbert, Christophe Poulard, Anniina Salonen
Understanding a material's dissipative response is important for their use in many applications, such as adhesion or fracture resistance. In dispersions, the interplay between matr…
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.…
