Viscoelasticity Enhances Contactless Adhesion of Soft Substrates
Marco Rizzo, Jacco H. Snoeijer, Vincent Bertin +1
Understanding adhesion is essential for describing stability, friction, and interfacial dynamics. Here, we investigate the adhesion force dynamics between a rigid sphere and a soft…
Butter on a hot pan: self-regulating dynamics of melt-lubricated sliding
Edoardo Bellincioni, Simon Biermann, Jacco H. Snoeijer +2
When solids melt while sliding down heated inclines, their motion is governed by a complex coupling between heat transfer, phase change, gravity and viscous dissipation. Despite re…
Dynamics of Poro-viscoelastic Wetting with Large Swelling
B. X. Zheng, T. S. Chan, E. H. van Brummelen +1
The deposition of droplets onto a swollen polymer network induces the formation of a wetting ridge at the contact line. Current models typically consider either viscoelastic effect…
Collective Effects in Breath Figures
Ambre Bouillant, Jacco H. Snoeijer, Bruno Andreotti
Breath figures are the complex patterns that form when water vapor condenses into liquid droplets on a surface. The primary question concerning breath figures is how the condensing…
Interfacial dripping faucet: generating monodisperse liquid lenses
Lorène Champougny, Vincent Bertin, Jacco H. Snoeijer +1
We present a surface analog to a dripping faucet, where a viscous liquid slides down an immiscible meniscus. Periodic pinch-off of the dripping filament is observed, generating a s…
Viscoelastic lubrication of a submerged cylinder sliding down an incline
Alexandros T. Oratis, Kai van den Berg, Vincent Bertin +1
Lubrication flows between two solid surfaces can be found in a variety of biological and engineering settings. In many of these systems, the lubricant exhibits viscoelastic propert…
