Nanoparticles assembled in new ways hold the promise of a wave of new high-tech materials that could offer high strength, enhanced magnetic properties, light reflectivity or absorption, use as catalysts and much more. Scientists at the U.S. Department of Energy's Ames Laboratory have developed a theoretical model to explore the effect of polymer coatings, including DNA, for self-assembly of nanocubes into so-called superlattices.

Scientists at the U.S. Department of Energy's Ames Laboratory are revealing the mysteries of new materials using ultra-fast laser spectroscopy, similar to high-speed photography where many quick images reveal subtle movements and changes inside the materials. Seeing these dynamics is one emerging strategy to better understanding how new materials work, so that we can use them to enable new energy technologies.
Testifying as a witness to the Standing Committee on Natural Resources of the Canadian House of Commons, Alex King, director of the Critical Materials Institute, a U.S. Department of Energy research hub at the Ames Laboratory, said that rare-earth metals and other materials critical to existing and emerging technologies are facing global shortages now and in the future.
Ames Middle School made a clean sweep of the 2014 Ames Laboratory Regional Middle School Science Bowl here Saturday. They won all three of their morning qualifying matches, then won four matches in the championship round to take the title. They will also join the Ames High School team in representing the Region at the Department of Energy's National Science Bowl in Washington, D.C. April 24-27.
Karl A. Gschneidner Jr., senior metallurgist at the U.S. Department of Energy's Ames Laboratory, was presented the 2014 Acta Materialia Materials and Society Award on February 18. The award honors scientists who have made a major positive impact on society through materials science.
