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.
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.
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.
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.
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.
