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.
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.
17-Apr-2017 How X-rays pushed topological matter research over the top
Pioneering X-ray experiments at Berkeley Lab's Advanced Light Source (ALS) helped bring to life decades-old theories about exotic topological states of matter, and the ALS continues to play an important role in this flourishing field of research.
13-Apr-2017 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.
27-Mar-2017 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.
14-Mar-2017 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.
9-Mar-2017 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.
2-Mar-2017 Exploring the evolution of nuclear deterrence through interviews, historical footage
Sandia National Laboratories explores the evolution of nuclear deterrence in a new documentary that combines modern and historical footage with a wide range of interviews. On Deterrence features interviews with former secretaries of defense, general officers, policymakers, analysts, scholars and scientists with varied viewpoints to describe the impact of nuclear deterrence since the end of World War II.
2-Mar-2017 Evaluating nuclear weapons: Sandia Labs taking a modern approach
Sandia National Laboratories is transforming how it assesses nuclear weapons in a stockpile made up of weapons at different stages in their lifecycles -- some systems that have existed for decades alongside those that have undergone life extension programs.
28-Feb-2017 The heat is on
NASA is developing a new family of flexible heat-shield systems with a woven carbon-fiber base material, and is using X-rays at Berkeley Lab's Advanced Light Source to test the designs.
21-Feb-2017 When rocket science meets X-ray science
NASA and Berkeley Lab researchers have teamed up to explore next-generation spacecraft materials at the microscale using an X-ray technique that produces 3-D images. This work could help ensure future spacecraft survive the rigors of otherworldly atmospheres.
20-Feb-2017 Breakthrough wireless sensing system attracts industry and government agency interest
Top experts in environmental sensing explored existing and potential applications for Waggle and other sensing technologies during a two-day workshop held at Argonne last year. From researching deforestation in the Amazon to improving air quality for manned space missions, attendees revealed unique ways to apply sensing technology to improve our understanding of Earth and human health -- and a number of these applications employed Waggle.
10-Feb-2017 Exploring mysteries on the surface
Ames Laboratory scientists Pat Thiel and Michael Tringides are explorers, discovering the unique properties of two-dimensional (2-D) materials and metals grown on graphene, graphite, and other carbon coated surfaces.
17-Jan-2017 Race for a better fuel begins with NREL researchers
Watching cars zoom around and around an oval track isn't Jesse Hensley's idea of a good time. Making them run on biofuel would be. On the Colorado campus of the Energy Department's National Renewable Energy Laboratory (NREL), where the posted speed limit is 20 mph, Hensley and his team have been racing toward a future where high-octane biofuel could push automobile performance further.
12-Jan-2017 Fast track control accelerates switching of quantum bits
An international collaboration among physicists at the University of Chicago, Argonne National Laboratory, McGill University and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit -- the basic unit of information in yet-to-be created quantum computers -- in findings published online Nov. 28 in Nature Physics. Their experiments on a single electron in a diamond chip could create quantum devices less prone to errors when operated at high speeds.
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.
