Adhesion, droplet dynamics, rough interfaces, roughness, surface tension The results in article number 2201873 suggest that a higher surface area and roughness promote the transition from bouncing to wetting of a droplet, benefiting surface design for facilitating droplet non-adhesion features during transport.
