A laser focus on super water-repellent metals

A laser focus on super water-repellent metals

February 23, 2018

Rochester researchers have been using lasers to change the properties of metals in incredible ways. But to make the technology commercially viable, a partnership between scholars and business will focus on making the lasers much more powerful.

Synthetic coatings: Super surfaces

Synthetic coatings: Super surfaces

March 25, 2015

Researchers are increasingly looking towards plants and animals for ideas on how to design coatings and textures that imbue surfaces with special properties. Two laser specialists at the University of Rochester in New York have used a laser to mill ridges into pieces of brass, platinum and titanium, and got a similar bouncing effect.
