ALBUQUERQUE, N.M. - Sunlight splitting water molecules to produce hydrogen using devices too small to be seen in a standard microscope. That's a goal of a research team from the National Nuclear Security Administration's Sandia National Laboratories. The research has captured the interest of chemists around the world pursuing methods of producing hydrogen from water. Sandia researchers John Shelnutt and Zhongchun Wang gaze upon the glow of porphryin nanotubes caused by the nanotubes’ intense resonance light scattering activity.
