22-Jul-2014 Sandia ensures US nuclear weapons deterrent can remain effective, credible
As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.
15-Jul-2014 Ames Laboratory home to first-in-nation DNP-NMR instrument to study materials
The US Department of Energy's Ames Laboratory is now the home to a dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer that helps scientists understand how individual atoms are arranged in materials. Ames Laboratory's DNP-NMR is the first to be used for materials science and chemistry in the United States.
14-Jul-2014 First anniversary gift for Critical Material Institute? Inventions. Eleven of them.
The Critical Materials Institute, an Energy Innovation Hub for the US Department of Energy, celebrated its first anniversary with 11 invention disclosures, all research milestones in a mission to assure the availability of rare earths and other materials critical to clean energy technologies.
The inventions include improved extractive processes, recycling techniques, and substitute materials -- technologies designed to increase production and efficiency of, and reduce reliance on, the use of rare earths and other critical materials.
15-May-2014 The brain: Key to a better computer
Although brain-inspired computing is in its infancy, Sandia National Laboratories has included it in a long-term research project whose goal is future computer systems. Neuro-inspired computing seeks to develop algorithms that would run on computers that function more like a brain than a conventional computer.
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.
