The team’s nanocones (scanning electron microscope image, (a)) were inspired by the nanotexture found on cicada wings (atomic force microscopy image, (b)). The middle plot (c) shows that the nanocones (red squares) are far less adhesive to warm water than the nanocylinders (blue circles). Because of the nanocone geometry, water droplets beneath a large drop can be reabsorbed (d) and small droplets condensing in cones can reconfigure at the top of the cones (e).

Nanotextures inspired by cone-shaped structures on cicada wings could inform new designs for materials prone to fogging, such as car and aircraft windshields. Several years ago, scientists at the U.S...
