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).

X-ray imaging and computer modeling help map electric properties of nanomaterials
Argonne researchers have developed a new approach for studying piezoelectric materials using ultrafast 3-D X-ray imaging and computer modeling. Their integrated approach, reported in Nano Letters, can help us better understand material behavior and engineer more powerful and energy-efficient technologies.

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.

SLAC celebrates Femtosecond Week
Got a millionth of a billionth of a second? There's science that actually happens on this timescale. Join us online for a week of ultrafast science from April 17 to 21. Learn more about how scientists and engineers use electron beams and bright pulses of light from the Linac Coherent Light Source X-ray laser and other advanced lasers to capture some of nature's speediest processes that occur in just femtoseconds, or quadrillionths of a second.

New SLAC theory institute aims to speed research on exotic materials at light sources
A new institute at the Department of Energy's SLAC National Accelerator Laboratory is using the power of theory to search for new types of materials that could revolutionize society -- by making it possible, for instance, to transmit electricity over power lines with no loss.

How did the proton get its spin?
Scientists once thought proton spin was simple to understand. However, after experiments in the 1980s proved their ideas wrong, researchers have been working to understand how the proton's components contribute to its spin. Scientists use the unique capabilities of the Relativistic Heavy Ion Collider and the Continuous Electron Beam Accelerator Facility, both DOE Office of Science user facilities, to explore this fundamental phenomenon.

Physicists move closer to listening in on sub-atomic conversation
Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing tools to allow them to listen in on the particles' gab fests and learn more about how they stick together to build our visible universe. The first complex calculations of a particle called the sigma have been carried out and published in Physical Review Letters.

Secrets to scientific success: Planning and coordination
Very often there are people behind the scenes of scientific advances, quietly organizing the project's logistics. New facilities and big collaborations require people to create schedules, manage resources, and communicate among teams. The US Department of Energy's Brookhaven National Laboratory is lucky to have Xiaofeng Guo in its ranks -- a skilled project manager who coordinates projects reaching across the US and around the world.

The power of 1
When it comes to creating new materials, single crystals play an important role in presenting a clearer picture of a material's intrinsic properties. A typical material will be comprised of lots of smaller crystals and the grain boundaries between these crystals can act as impediments, affecting properties such as electrical or thermal resistance.

Two-dimensional MXene materials get their close-up
Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2D) ceramics called MXenes are contenders. ORNL scientists using state-of-the-art scanning transmission electron microscopy provided the first direct evidence of the atomic-defect configurations in a titanium-carbide MXene synthesized at Drexel University. Published in ACS Nano, a journal of the American Chemical Society, the study coupled atomic-scale characterization and electrical property measurements with theory-based simulation.

Cracking the Mystery of Perfect Efficiency: Investigating Superconductors
A whole new area of research emerged from the discovery of superconductivity in 1911. Since then, scientists have learned why some materials superconduct near absolute zero and have discovered 'high-temperature' superconductors. Now, researchers supported by the Department of Energy's Office of Science are working to identify a common characteristic of high-temperature superconductors in hopes of one day developing one that works at room temperature.
