Sandia research points way toward chameleon-like camouflage
April 7, 2009
Sandia National Laboratories researchers have demonstrated that, in theory, they could cause synthetic materials to change color like fish do.

Four R&D 100 Awards Won by Sandia Labs
July 28, 2005
Ion-Photon Emission Microscope — Sandia earned a third R&D 100 award for the invention of a patented exploratory ion beam microscope system that does not require costly and complicated forming and focusing equipment. Joint winner Quantar Technologies is marketing this invention. The multidimensional, high-resolution analysis system is called the Ion-Photon Emission Microscope (IPEM). It allows scientists and engineers to microscopically study the effects of single ions in air on semiconductors, semiconductor devices, and biological cells without having to focus the beam. The technique determines the position at which an individual ion enters the surface of a sample; thus, focusing a beam is unnecessary.
