Magnetic mixing creates quite a stir
October 27, 2009

Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create mixing, with only “mixed” success. “In small devices,” says Sandia materials scientist Jim Martin “people have tried all kinds of pillars and mixing cells to initiate mixing, but these approaches don’t work well.”

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.   "Camouflage outfits that blend with a variety of environments without need of an outside power source — say, blue when at sea and then brown in a desert environment — is where this work could eventually lead,” says principal investigator George Bachand. “Or the same effect could be used in fabricating chic civilian clothing that automatically changes color to fit different visual settings.”

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.
