Scientists make metal surfaces water-repellent

Two University of Rochester scientists have found a way of using powerful laser beams to make metal surfaces last longer and be more suitable for a wide range of practical purposes.

"We change the nature of the metal surface so that they can repel water," said Chunlei Guo, who is a professor of optics and physics at UR.

Guo and Anatoliy Vorobyev, who is a senior scientist with Guo at UR's Institute of Optics, detail their findings in an article appearing on Tuesday in the Journal of Applied Physics.

The process that they have developed changes the surface of metals by repeatedly subjecting the surface to bursts of lasers.

Water tends to stick and spread on metal surfaces, but that doesn't happen on the treated ones.
