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…

Elastocapillary menisci mediate interaction of neighboring structures at the surface of a compliant solid
Lebo Molefe, John Kolinski
Surface stress drives long-range elastocapillary interactions at the surface of compliant solids, where it has been observed to mediate interparticle interactions and to alter the…

The characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica
Ramin Kaviani, John M. Kolinski
Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the air is compressed into a thin film, slo…
