Leafy inspiration: this artificial surface with 3D ratchet structures enables liquids of different surface tension to move in different directions. It was inspired by Araucaria leaves, which are also ...

Figure 1: Wave fields and surface flows produced by the cylindrical wave maker. Figure 2: Characteristics of the wave-driven inward and outward jets. Although the mean flow is driven by waves, which ...

Researchers from the University of Washington want to improve the pipe. Specifically, they are developing a flexible pipe with an interior helical structure that makes fluid flow one way and not the ...
