29-Jan-2014 NERSC celebrates 40 years at the forefront
This year, the Department of Energy's National Energy Research Scientific Computing Center (NERSC) is celebrating yet another milestone: its 40th anniversary.
29-Jan-2014 Letting in the light
Oak Ridge National Laboratory is developing a low-cost, transparent, anti-soiling coating for solar reflectors to optimize energy efficiency while lowering operating and maintenance costs and avoiding negative environmental impacts.
27-Jan-2014 Deployments of network monitoring software perfSONAR hit 1,000
Finding the network bottlenecks that can slow the flow of science data sets and impede research can be extremely complex, especially as such data transfers cross a multitude of linked networks. But perfSONAR, a network monitoring software package developed jointly by DOE's Energy Sciences Network, national labs, universities and Internet 2, is making that task much easier. In January 2014, the number of perfSONAR instances installed in the US and 13 other countries reached 1,000.
16-Jan-2014 Top 10 Brookhaven Lab breakthroughs of 2013
2013 was a banner year for science at the US Department of Energy's Brookhaven National Laboratoryfrom our contributions to Nobel Prize-winning research to new insights into catalysts, superconductors, and other materials key to advancing energy-efficient technologies.
7-Jan-2014 The play-by-play of energy conversion: Catching catalysts in action
Before catalysis unfolds in a laboratory, scientists painstakingly assemble the materials and spark a reaction. But many experimental techniques only capture the static details before and after the reaction. Now, researchers at the US Department of Energy's Brookhaven National Laboratory have demonstrated an unprecedented ability to peer into the dynamic, real-time reactions blazing along at scales spanning just billionths of a meter, producing a sort of play-by-play view of the chemistry in action.
16-Dec-2013 Small size enhances charge transfer in quantum dots
In a study just published in the journal Chemical Communications, scientists at the US Department of Energy's Brookhaven National Laboratory, Stony Brook University, and Syracuse University show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light.
29-Oct-2013 NREL brings precision, savings to energy audits
An energy audit tool that more accurately pinpoints potential energy savings while potentially costing 35 percent to 75 percent less than traditional audits is set to hit the multi-billion-dollar energy retrofit industry next year.
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.
27-Aug-2013 Third consecutive IEEE Cherry Award for NREL
Keith Emery always had amazing computer programming skills, but he lacked that special gift for creating solar cells. So, 30 years ago he switched to something more in his wheelhouse -- characterizing and measuring the efficiency of solar cells and modules.
13-Aug-2013 Wood-boring gribbles intrigue researchers
Tiny wood borers known colloquially as gribbles make their own enzymes and use them to eat through docks in harbor towns, earning enmity from fishermen all around the world.
13-Aug-2013 Interns make robust contribution to NREL
They travel far and wide, from all corners of the country. They come from a diverse set of backgrounds, and they have very different plans for their futures. But the 54 student interns at the Energy Department's National Renewable Energy Laboratory this summer all have something in common -- a thirst for knowledge and a desire to apply what they have learned in school to real-world science in a state-of-the-art laboratory environment.
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.
14-Jun-2013 Detecting homemade explosives, not toothpaste
Sandia National Laboratories researchers want airports, border checkpoints and others to detect homemade explosives made with hydrogen peroxide without nabbing people whose toothpaste happens to contain peroxide.
7-Jun-2013 X-rays from NSLS reveal fuel cells in action
Wouldn't it be great to have a magical "energy box" that could convert a wide array of fuels to electricity with high efficiency and lower emissions? Solid oxide fuel cells show significant promise. But these solid-state energy-conversion devices are made of complex materials and they require specific conditions for optimal operation -- high temperatures, variable pressures, and electrical polarization.
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.
