Figure Legend:
Droplet removal and a new cycle of droplet nucleation. (a) Time-lapse ESEM images of jumping droplets upon coalescence. Droplet jumping was followed by a new cycle of nucleation. The dashed ovals highlight the droplets prior to coalescence jumping and emptied spots after jumping. The dashed rectangle highlights the newly formed droplets. The dewetting transition of the droplet base was crucial for coalescence jumping enforced by the excess surface free energy released upon coalescence. (b) Illustration of the droplet nucleation, growth, partial depinning, and coalescence jumping processes.
