Laser Turns All Metals Black

Roland Piquepaille writes "Researchers at the University of Rochester have found a way to change the properties of almost any metal by using a femtosecond laser pulse. This ultra-intense laser blast creates true 'black metal' from copper, gold or zinc by forming nanostructures at the surface of the metal. As these nanostructures capture radiation, the metals turn black. And as the process needs surprisingly low power, it could soon be used for a variety of applications, such as stealth planes, black jewels or car paintings. But read more for additional references and a picture of this femtosecond laser system."

Well, to be honest, I don't really like black metal. I heard it's less reliable, and doesn't act appropriately, despite all we've done to help it perform. Once black metal is in your neighborhood, property values go down and people try to leave ASAP. I've never seen a black metal do a job right without having to be replaced. If my daughter were interested in a black metal, I'd steer her another way as best I could. I don't serve black metal either.
