Solutal Marangoni flow as the cause of ring stains from drying salty colloidal drops
Alvaro Marin, Stefan Karpitschka, Diego Noguera-Marín +4
Evaporating salty droplets are ubiquitous in nature, in our home and in the laboratory. Interestingly, the transport processes in such apparently simple systems differ strongly fro…
Dynamic solid surface tension causes droplet pinning and depinning
Mathijs van Gorcum, Bruno Andreotti, Jacco H. Snoeijer +1
The contact line of a liquid drop on a solid exerts a nanometrically sharp surface traction. This provides an unprecedented tool to study highly localised and dynamic surface defor…
Printing wet-on-wet: attraction and repulsion of drops on a viscous film
M. A. Hack, M. Costalonga, T. Segers +3
Wet-on-wet printing is frequently used in inkjet printing for graphical and industrial applications, where substrates can be coated with a thin liquid film prior to ink drop deposi…
Delayed coalescence of surfactant containing sessile droplets
Myrthe A. Bruning, Maxime Costalonga, Stefan Karpitschka +1
When two sessile drops of the same liquid touch, they merge into one drop, driven by capillarity. However, the coalescence can be delayed, or even completely stalled for a substant…
