- Asymmetric-anisotropic (directional) fog collection behaviour is observed for leaves of the arid climate plant species Eremopyrum orientale. This is underpinned by a hierarchical surface structure comprising macroscale grooves, microscale tilted cones (in the direction of water flow), and nanoscale platelets. Soft lithography combined with either nanocoating deposition or functional nanoimprinting has been used to replicate this highly-efficient directional water collection mechanism.
