Laser-etched metal 'bounces' water -BBC
Multifunctional surfaces produced by femtosecond laser pulses - Journal of Applied Physics
I can think of some really useful applications for a processes like the one specify.
Many efforts to produce such "superhydrophobic" surfaces have relied on coatings, but this approach permanently changes the shape of the metal's surface.
"The structures created by our laser on the metals are intrinsically part of the material surface," said senior author Prof Chunlei Guo.
"The material is so strongly water-repellent, the water actually gets bounced off. Then it lands on the surface again, gets bounced off again, and then it will just roll off from the surface."]
