Comments Off on Scientists Discover New Technique To Change the Color of Gold Without Using Chemicals

Photo by  Shutterstock Researchers at the  University of Southampton  have developed a new way to alter the color of gold—or just about any metal—  without  chemically altering it. The technique involves “nano-patterning” — etching the metal’s surface with patterns of specific shape and depth, which manipulates the wavelengths that are visible to the human eye. The technique could deliver valuable economic and environmental benefits, and it could be harnessed to manufacture jewelry and to make banknotes and documents more difficult to forge.

Photo: Sean MacEntee / CC Part of the magic of Disneyland is that you never see what’s behind the “magic” – the workers in the mascot costumes, the networks of underground tunnels, and all the computers that keep everything running. But for once, it’s more interesting to see what’s going on with those computers than with Mickey and Goofy- because the heat they generate is being recovered as energy for nearby homes and offices….
