A new x-ray beam technique tracks atomic-level changes under real-world operating conditions.
Measured strong coupling of vibrations and electrons could lead to controlled magnetism and electronic properties.
Observations and measurements of a neutron star merger have largely ruled out some theories relating to gravity and dark energy, and challenged a large class of cosmological theories.
Focused x-ray beam revealed structural changes from laser heating, pinning down elusive melting point.
UPTON, NY-- As scientists have explored the structure and properties of matter at ever deeper levels they've discovered many exotic new materials, including superconductors that carry electric current with no resistance, liquid crystals that align to produce brilliant dynamic displays, and materials exhibiting various forms of magnetism.
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a new process to sheathe metal under a single layer of graphite which may lead to new and better-controlled properties for these types of materials.
Chemical Engineering Prof Daniel Esposito has developed a novel photovoltaic-powered electrolysis device that can operate as a stand-alone platform that floats on open water. His floating PV-electrolyzer can be thought of as a "solar fuels rig" that bears some resemblance to deep-sea oil rigs--but it would produce hydrogen fuel from sunlight and water instead of extracting petroleum from beneath the sea floor.

The Florida State University-headquartered National High Magnetic Field Laboratory has shattered another world record with the testing of a 32-tesla magnet -- 33 percent stronger than what had previously been the world's strongest superconducting magnet used for research and more than 3,000 times stronger than a small refrigerator magnet.
A greater understanding of the dynamics of chemical reactions is leading to better models of atmospheric chemistry. Through this work, scientists are gaining insight into a key chemical able to break down some major air pollutants.
An international team of scientists --- including several researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory -- - has discovered an anode battery material with superfast charging and stable operation over many thousands of cycles.
Shining light on a growing semiconductor modifies its interface with the surface and could improve the optical properties of each.
Vector polarizers are a light filtering technology hidden behind the operation of many optical systems. They can be found, for instance, in sunglasses, LCD screens, microscopes, microprocessors, laser machining and more. Optical physicists published details of their new vector polarizer design this week in APL Photonics. The newly proposed design is a major advance in polarization technology because it enables flexible filtering of a wide range of light sources and generation of new light states.
Scientists have come up with a way to massively speed up the ordering process for self-assembling materials. The resulting ultra-small, well-ordered patterns could be used in the fabrication of microelectronics, antireflective surfaces, magnetic data storage systems, and fluid-flow devices.
Neuroscientists can now explore a beta version of the new Neurodata Without Borders: Neurophysiology (NWB:N 2.0) software and offer input to developers before it is fully released next year.
Researchers from Stanford University, two Department of Energy national labs and the battery manufacturer Samsung created a comprehensive picture of how the same chemical processes that give cathodes their high capacity are also linked to changes in atomic structure that sap performance.
A new Petascale Data Transfer Node project aims to to achieve regular disk-to-disk, end-to-end transfer rates of one petabyte per week between major supercomputing facilities, which translates to achievable throughput rates of about 15 Gbps on real world science data sets.
Soil microbes work as both decomposers and synthesizers of carbon compounds in soil, offering new answers with impacts to crops and eco-health.
Scientists reduce uncertainties in future climate prediction by directly coupling an energy-economy model to an Earth system model.
Scientists show that grasslands are more sensitive to changes in the amount of moisture in the air than to changes in precipitation.
Scientists evaluate seven hydrologic models to understand how each model agrees and differs.
New Research Shows Hydropower Dams Can Be Managed Without an All-or-Nothing Choice Between Energy and Food
Nearly 100 hydropower dams are planned for construction along tributaries off the Mekong River's 2,700-mile stretch. In Science Magazine, researchers present a mathematical formula to balance power generation needs with needs of fisheries downstream.
Atmospheric Radiation Measurement (ARM) observations provide clues on atmospheric contributions to an Antarctic melt event.
