Inverted Cheerios effect: Liquid drops attract or repel by elasto-capillarity
S. Karpitschka, A. Pandey, L. A. Lubbers +5
Solid particles floating at a liquid interface exhibit a long-ranged attraction mediated by surface tension. In the absence of bulk elasticity, this is the dominant lateral interac…
Drops on soft solids: Free energy and double transition of contact angles
Luuk A. Lubbers, Joost H. Weijs, Lorenzo Botto +3
The equilibrium shape of liquid drops on elastic substrates is determined by minimising elastic and capillary free energies, focusing on thick incompressible substrates. The proble…
Why is surface tension a force parallel to the interface?
Antonin Marchand, Joost H. Weijs, Jacco H. Snoeijer +1
A paperclip can float on water. Drops of mercury refuse to spread on a surface. These capillary phenomena are macroscopic manifestations of molecular interactions, and can be expla…
Why surface nanobubbles live for hours
Joost H. Weijs, Detlef Lohse
We present a theoretical model for the experimentally found but counter-intuitive exceptionally long lifetime of surface nanobubbles. We can explain why, under normal experimental…
Initial spreading of low-viscosity drops on partially wetting surfaces
Koen G. Winkels, Joost H. Weijs, Antonin Eddi +1
Liquid drops start spreading directly after brought into contact with a partial wetting substrate. Although this phenomenon involves a three-phase contact line, the spreading motio…
Diffusive shielding stabilizes bulk nanobubble clusters
Joost H. Weijs, James R. T. Seddon, D. Lohse
Using molecular dynamics, we study the nucleation and stability of bulk nanobubble clusters. We study the formation, growth, and final size of bulk nanobubbles. We find that, as lo…
