Unsinkable Hydrophobic Structures

Unsinkable Hydrophobic Structures
Ants and spiders have inspired an unsinkable, hydrophobic metal that could have applications in ships and ocean monitoring devices.

The unsinkable structure was created by a team from the University of Rochester, who first etched a metal surface with a nanoscale pattern to cause the material to become hydrophobic and buoyant. In order to prevent the etchings from wearing down over time and increase bouyancy, the team then connected the two etched aluminum plates face to face with a small pole. Air is trapped in the space between the plates, resulting in a structure that is virtually unsinkable.
