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.
13-Mar-2017 Nidia Gallego: Carbon scientist is as versatile as the element she studies
At the Department of Energy's Oak Ridge National Laboratory, Nidia Gallego develops carbon materials for energy technologies and space exploration. She investigates the physical and chemical properties of carbon in diverse forms -- including fiber, composites and foam.
'Carbon is a single element that can be many things,' Gallego said. 'It can be hard like diamond, soft like graphite or amorphous like activated carbon. Its material properties depend on how carbon atoms bond with each other.'
Argonne researchers have developed a new theoretical approach, ideally suited for high-performance computing systems, capable of making predictive calculations about particle interactions that conform almost exactly to experimental data. This new approach could give scientists a valuable tool for describing new physics and particles beyond those currently identified.
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 Argonne hosts 15th annual Introduce a Girl to Engineering Day
IGED is a diversity outreach program designed to provide 8th-grade girls an opportunity to learn about science, technology, engineering and mathematics (STEM) careers. Students are assigned to engineer and scientist mentors who accompany the girls throughout the day's scheduled activities.
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.
1-Mar-2017 Jefferson lab director honored with Energy Secretary Award
Hugh Montgomery, director of the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab), was awarded The Secretary's Distinguished Service Award by the Secretary of Energy earlier this year. This honor highlights Montgomery's contributions to the research programs at the DOE national labs, both as a world-leading researcher and as a more than 30-year DOE national laboratory employee.
1-Mar-2017 Corrective 'eyeglasses' now available for X-ray research facilities
A research collaboration designed and built special spectacles, or corrective phase plates, for use at light sources that use high-intensity X-rays to probe matter in fine detail. Nature Communications published the details of the method, developed in part by researchers at the Department of Energy's SLAC National Accelerator Laboratory.
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.
27-Feb-2017 New droplet-on-tape method assists biochemical research at X-ray lasers
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory, Brookhaven National Laboratory, and other institutes designed a new assembly-line system that rapidly replaces exposed biological samples by moving droplets along a miniature conveyor belt, timed to coincide with the arrival of the X-ray pulses. The droplet-on-tape system now allows the team to study the biochemical reactions in real-time from microseconds to seconds, revealing the stages of these complex reactions.
21-Feb-2017 Sandia using kinetics, not temperature, to make ceramic coatings
Sandia National Laboratories is working on a way to lay down ceramic coatings kinetically and at room temperatures. Coating at room temperature makes microelectronics design and fabrication more flexible and could someday lead to better, less expensive microelectronics components that underpin modern technology.
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.
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.
