Your kidding, right? Did you click on the first link? I mean, all we can really do is read their paper, right? That article contained the link. Jeez, you're a lazy one. http://scitation.aip.org/content/aip/journal/jap/117/3/10.1063/1.4905616 "The researchers created the surfaces by zapping platinum, titanium and brass samples with extremely short femtosecond laser pulses that lasted on the order of a millionth of a billionth of a second. “During its short burst the peak power of the laser pulse is equivalent to that of the entire power grid of North America,” Guo said. These extra-powerful laser pulses produced microgrooves, on top of which densely populated, lumpy nanostructures were formed. The structures essentially alter the optical and wetting properties of the surfaces of the three metals, turning the normally shiny surfaces velvet black (very optically absorptive) and also making them water repellent."
