Blue sunflower? This is really a microscope image of liquid droplet residue from water-based chemicals, one-half millimeter wide. The droplets on the outer edges are 50 times less wide, and seven times less wide than a human hair. This image, titled "Blue Sun Flower," was created by Devin Brown, senior research engineer at the Institute for Electronics and Nanotechnology at the Georgia Institute of Technology. The image won grand prize in the 2013 EIPBN (Electron, Ion and Photon Beam Technology and Nanofabrication) micrograph contest. (Credit: Devin K.
