Lasers Help Metal Resist Rust and Ice
Water droplets might slide off your Teflon-coated pan, but what if they bounced off immediately instead? Scientists at the University of Rochester are pioneering a new way to make metals more water-repellent. The researchers used lasers to fundamentally alter the metal by creating micro- and nanoscale structures on its surface. Physicist Chunlei Guo, one of the authors of the study published this week in the Journal of Applied Physics, explains possible real-world applications of this technology.
