X-rays from NSLS reveal fuel cells in action

DOE/Brookhaven National Laboratory

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.

DNA-guided assembly yields novel ribbon-like nanostructures

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement -- with the rods forming "rungs" on ladder-like ribbons could result in the fabrication of new nanostructured materials with desired properties.

Recipe for low-cost, biomass-derived catalyst for hydrogen production

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Researchers at Brookhaven National Laboratory describe details of a low-cost, stable, effective catalyst that could replace costly platinum in the production of hydrogen. The catalyst, made from renewable soybeans and abundant molybdenum metal, produces hydrogen in an environmentally friendly, cost-effective manner, potentially increasing the use of this clean energy source.

Accelerating particles accelerates science -- with big benefits for society

DOE/Brookhaven National Laboratory

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.

Laser mastery narrows down sources of superconductivity

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2D materials, collaborating scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.

Dopants dramatically alter electronic structure of superconductor

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Study demonstrates that doping dramatically alters the atomic-scale electronic structure of the parent of a high-temperature superconductor, with important consequences for the behavior of the current-carrying electrons. The findings could potentially point to new ways to design superconductors with improved properties.

Scientists turn toxic by-product into biofuel booster

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists studying an enzyme that naturally produces alkanes, long carbon-chain molecules that could be a direct replacement for the hydrocarbons in gasoline, have figured out why the natural reaction typically stops after three to five cycles -- and devised a strategy to keep the reaction going. The work could renew interest in using the enzyme in bacteria, algae, or plants to produce biofuels that need no further processing.

Chemistry building at Brookhaven Lab named Historic Chemical Landmark

DOE/Brookhaven National Laboratory
Grant and Award Announcement

The New York Section of the American Chemical Society has designated the Chemistry Building at Brookhaven National Laboratory as an Historic Chemical Landmark for the synthesis of 18^FDG, a radiotracer that has had a revolutionary and global impact on cancer diagnosis and management and brain research.

Biologists describe details of new mechanism for molecular interactions

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Scientists have discovered a new mechanism that may alter principle understandings of molecular interactions within a cell's nucleus. In four papers, the scientists describe the details of how particular proteins use a "molecular sled" to slide along DNA -- much like a train running along its tracks -- to find and interact with other proteins. The findings suggest this mechanism may be universal.

Computational model IDs potential pathways to improve plant oil production

DOE/Brookhaven National Laboratory
Peer-Reviewed Publication

Using a computational model they designed to incorporate detailed information about plants' interconnected metabolic processes, scientists at the US Department of Energy's Brookhaven National Laboratory have identified key pathways that appear to "favor" the production of either oils or proteins. The research, now published online in Plant Physiology, may point the way to new strategies to tip the balance and increase plant oil production.
