31-Mar-2014 Ames Lab researchers show polymer-coated nanocubes form complex structures
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 US 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.
17-Oct-2013 Architects and building engineers flock to NREL
Eight busloads of architects and mechanical engineers toured one of the world's largest net-zero-energy office building this summer at the Energy Department's National Renewable Energy Laboratory and came away inspired with new ideas for how to design and build beautiful, eco-friendly structures on a budget.
25-Jul-2013 Project Neptune: Specialized gas detection for nonproliferation
Sandia National Laboratories' Project Neptune aims to design a system capable of sensing, from among the loud signals of a lot of gases, the weak signals from specific gases that are signs of nuclear proliferation. The researchers believe their gas correlation technique will prove ideal for a simple, inexpensive sensor to monitor those few illusive gases.
1-Jun-2011 The curious case of germanium-72
Physicists from Oak Ridge National Laboratory, the University of Tennessee, and Germany's GSI in Darmstadt recently used ORNL's Jaguar supercomputer to explore the pair bonding of neutrons in one uncommon isotope -- germanium-72. In doing so they discovered that changes in temperature and rotation take the nucleus through at least two physical phases.
13-Jul-2010 Ethanol-fueled racecar engines outpower lead-fueled engines
A group of automotive researchers from the US Department of Energy's Argonne National Laboratory and industry have shown that a fuel-injected racing car engine fueled by E-85, an ethanol-based fuel, outperforms the same engine with a carburetor and leaded racing fuel.
4-Jun-2009 Ames Laboratory-made materials are out of this world
Materials produced at the US Department of Energy's Ames Laboratory were launched into space on May 14 with the European Space Agency's Planck Mission. Ames Laboratory's Materials Preparation Center synthesized over 20 kilograms of a lanthanum-nickel-tin alloy for use in a metallic hydride sorption cryocooler system -- built by NASA's Jet Propulsion Laboratory -- that will cool instruments during the space mission.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
