Drops can Perpetually Bounce over a Vibrating Wettable Solid
Lebo Molefe, Tomas Fullana, François Gallaire +1
On the surface of a vibrating liquid bath, instead of coalescing, a drop will continually bounce on a thin film of air between the drop and the free surface, giving rise to rich ch…

Marangoni-driven flow instability accelerates liquid-solid contact on atomically smooth mica
Octave Castanedo, John M. Kolinski
A droplet falling toward a solid surface displaces the surrounding air until it encounters a defect, and contact nucleates. On atomically smooth surfaces devoid of defects, contact…

Coating thickness prediction for a viscous film on a rough plate
Lebo Molefe, Giuseppe A. Zampogna, John M. Kolinski +1
Surface roughness significantly modifies the liquid film thickness entrained when dip coating a solid surface, particularly at low coating velocity. Using a homogenization approach…
