Condensate microdrop self-propelling (CMDSP) is observed on superhydrophobic titanium-based array architecture structure surfaces via a facile one-step electrochemical anodization method. In article number 1600687, Y. K. Lai and co-workers show how the microdroplets can realize the enhanced CMDSP ability, powered by excess surface energy released from the microdrops coalescence on the rationally designed hierarchical TiO2 particle array surfaces with special superwettability, for promising applications in water-harvesting.
