19-May-2017 A fresh math perspective opens new possibilities for computational chemistry
A new mathematical "shortcut" developed by Berkeley Lab researchers is speeding up molecular absorption calculations by a factor of five, so simulations that used to take 10 to 15 hours to compute can now be done in approximately 2.5 hours. These algorithms will be incorporated in an upcoming release of the widely used NWChem computational chemistry software suite later this year.
10-May-2017 Low-energy RHIC electron cooling gets green light, literally
Scientists at Brookhaven Lab have produced a powerful green laser‹the highest average power green laser ever generated by a single fiber-based laser‹which will be crucial to experiments in nuclear physics at the Lab¹s Relativistic Heavy Ion Collider (RHIC).
5-May-2017 Bacterial boost for bio-based fuels
"Electrical" bacteria are the key ingredient in a new process developed by the Oak Ridge National Laboratory that recycles wastewater from biofuel production to generate hydrogen. The hydrogen can then be used to convert bio-oil into higher grade liquid fuels such as gasoline or diesel.
5-May-2017 Brookhaven's John Shanklin named a Battelle 'Inventor of the Year'
John Shanklin, a biochemist investigating the fundamental processes that underlie the production of plant oils at the US Department of Energy's (DOE) Brookhaven National Laboratory, is being honored as an "Inventor of the Year" by Battelle -- the global science and technology organization that, together with Stony Brook University, manages Brookhaven Lab through the company Brookhaven Science Associates.
5-May-2017 Speedy X-ray detector arrives at NSLS-II
The National Synchrotron Light Source II (NSLS-II), a DOE Office of Science User Facility at the US Department of Energy's Brookhaven National Laboratory, is a truly international resource.
4-May-2017 New effort by Argonne helps power utilities and others better plan for the future
If you're an electric utility planning a new power plant by a river, it would be nice to know what that river will look like 20 years down the road. Will it be so high that it might flood the new facility? Will the water be so low that it can't be used to cool the plant? A new initiative by Argonne combines climate data and analysis with infrastructure planning and decision support to offer real help.
3-May-2017 Researchers develop a new catalyst for water splitting
Water-splitting systems require a very efficient catalyst to speed up the chemical reaction that splits water into hydrogen and oxygen, while preventing the gases from recombining back into water. Now an international research team, including scientists at the Department of Energy's SLAC National Accelerator Laboratory, has developed a new catalyst with a molybdenum coating that prevents this problematic back reaction and works well in realistic operating conditions.
24-Apr-2017 Machine learning dramatically streamlines search for more efficient chemical reactions
In theory, a catalytic reaction may follow thousands of possible paths, and it can take years to identify which one it actually takes so scientists can tweak it and make it more efficient. Now researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have taken a big step toward cutting through this thicket of possibilities.
21-Apr-2017 Beyond femtoseconds
Hopefully you've discovered this week how femtosecond science provides revolutionary views of some of nature's fastest phenomena. You now know how mind-bogglingly fast a femtosecond passes, and you might be thinking things couldn't get much faster. Well, let's talk about the attosecond.
21-Apr-2017 What can you study in femtoseconds? Materials
When Aaron Lindenberg was introduced to ultrafast science as a first-year grad student at UC Berkeley, he was immediately hooked. He knew he wanted to be part of a hot research field that explores nature's speediest processes and lets us see the world with different eyes.
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.
