Adhesive forces in droplet kinetic friction
Glen McHale, Sara Janahi, Hernán Barrio-Zhang +4
Kinetic frictional forces resisting droplet motion often appear to be separate to surface wettability and adhesive forces. Here we show that such friction arises from a simple comb…

Multiple Equilibria Enables Tunable Wetting of Droplets on Patterned Liquid Surfaces
Xitong Zhang, Hongyu Zhao, Jack R. Panter +4
Patterning solid surfaces with varying wettability is important to manage droplets in microfluidics, heat transfer and printing. Solid surface roughness poses fundamental limitatio…
