Like La Salle in 1685, researchers at Texas A&M University are in uncharted waters as they try to reconstruct his vessel with a gigantic freeze-dryer, the first undertaking of its size.

Nanostructures to realize hydrogen's energy potential

August 15, 2012 6:40 am | News | Comments

For the first time, engineers at the University of New South Wales have demonstrated that hydrogen can be released and reabsorbed from a promising storage material, overcoming a major hurdle to its use as an alternative fuel source. The researchers have synthesized nanoparticles of a commonly overlooked chemical compound called sodium borohydride and encased these inside nickel shells.

An intriguing twist in the structure of a cobalt oxide catalyst

August 15, 2012 5:41 am | by David Lindley | News | Comments

Hydrogen is a clean fuel, producing only water vapor when it burns. But generating hydrogen in large quantities and in a "green" fashion is not straightforward. Biological photosynthesis includes an efficient reaction step that splits water into hydrogen and oxygen with the help of catalysts that have been used as models for synthetic catalysts. Working at the Advanced Photon Source at Argonne National Laboratory, a team of scientists has determined the structure of one such catalyst, a complex cobalt oxide.

New platinum-based catalyst design works better, lasts longer

Photos reflect light like 3D objects with novel printing technology

August 14, 2012 4:48 am | News | Comments

A novel printing method yields photos that respond to different angles of light the same way a 3D object does. The technique, which uses specially designed "reflectance paper" covered with thousands of tiny dimples, was developed by a team of researchers at the University of California, Santa Cruz; Hewlett-Packard Laboratories; and 3M.

New insight into independent control of ionic, electronic conductivity of materials

August 14, 2012 4:19 am | News | Comments

Lawrence Livermore National Laboratory researchers have discovered a new method to independently control ionic and electronic conductivities in certain solids.
