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.
6-Dec-2013 Tiny drops of hot quark soup -- how small can they be?
New analyses of deuteron-gold collisions at the Relativistic Heavy Ion Collider indicate that collisions between gold ions and much smaller deuterons, designed as control experiments, may be serving up miniscule drops of hot quark-gluon plasma.
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.
26-Sep-2013 Supercomputers help solve a 50-year homework assignment
A group of theoretical physicists has solved half of a 50-year homework assignment -- a calculation of one type of subatomic particle decay aimed at helping to answer the question of why the early universe ended up with an excess of matter.
18-Sep-2013 Supercomputing the transition from ordinary to extraordinary forms of matter
Supercomputing calculations plus experimental data from the Relativistic Heavy Ion Collider are helping scientists map out the nuclear phase diagram. This research offers insight into the transition of quark-gluon plasma to ordinary matter -- which mimics the formation of visible matter in the universe today.
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.
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.
29-Apr-2013 A solar booster shot for natural gas power plants
Natural gas power plants can use about 20 percent less fuel when the sun is shining by injecting solar energy into natural gas with a new system being developed by the Department of Energy's Pacific Northwest National Laboratory.
13-Mar-2013 Accelerating particles accelerates science -- with big benefits for society
Tackling the most challenging problems in accelerator science attracts the world's best and brightest to Brookhaven Lab. It's only natural that ideas and techniques born here take root in new research facilities around the world -- and spark a host of spin-off applications for industry, medicine, national security, and more.
15-Jan-2013 Sandia airborne pods seek to trace nuclear bomb's origins
If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis.
16-Nov-2012 Growth Forum offers networking nirvana
A greener detergent, a better solar-cell coating, an off-the-grid freezer -- clean-tech entrepreneurs pitched their ideas to money-men and -women in 10-minute bursts at the 2012 Industry Growth Forum last month in Denver.
The US Department of Energy's National Renewable Energy Laboratory held the 25th Industry Growth Forum, an annual event that features presentations from emerging clean energy companies, provocative panels led by thought leaders, one-on-one meetings, and organized networking opportunities.
21-Aug-2012 Scientists create new diamond-denting carbon
A new super-hard form of carbon has been created by an international team of scientists working with X-rays at the Advanced Photon Source at Argonne National Laboratory.
17-Jul-2012 Special report: Graphics processing units speed results in extreme-scale supercomputers
Can scientists and engineers benefit from extreme-scale supercomputers that use application-code accelerators called GPUs (graphics processing units)? Comparing GPU accelerators with today's fastest central processing units (CPUs), early results from diverse areas of research show 1.5- to 3-fold speedups for most codes. That acceleration means increased realism of simulations and decreased time to results. A special report details these findings.
12-Jul-2012 Idaho researcher building used nuclear fuel sensor
Much of the 6,200 metric tons of used nuclear fuel generated by US power plants over the last 40 years is stored safely in giant stainless steel casks. Darryl Butt, a Boise State University professor, is part of a team researching whether it can be stored that way for at least 60 more.
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.
