Summary: Water droplets detach rapidly from rotating surfaces with micro/nanotextures in a doughnut shape, reducing the contact time by about 40% compared with stationary surfaces. The droplets fragment into satellites and scatter spontaneously to avoid further collision with the substrate. Furthermore, the contact time is highly dependent on the impact velocities of the droplets, surpassing the classical inertial-capillary scaling law. These results not only deepen the fundamental understanding of droplet dynamics on moving surfaces but also suggest a synergistic mechanism to actively regulate the contact time by coupling the kinematics of droplet impingement and surface rotation.

Summary: Tailoring the dynamics of condensation frosting by surface topological designs is a promising approach to mitigate frost accretion, but challenging due to complex interactions. In this study, a design of nanowire clusters isolated by grooves is proposed to regulate multiphase changes. By controlling the topology precisely, condensates can be localized on the cluster edges in stable Cassie state and droplets can be efficiently removed even at extremely low temperatures. The remaining droplets show reduced size and large spacing, hindering ice bridging and freezing. The duration of anti-frosting and frosting is significantly increased compared to other surfaces.
