Cornell researchers, Ithaca, N.Y., have used high-resolution 3D imaging to detect, for the first time, the atomic-scale defects in computer chips that can sabotage their performance using a new imaging technique called electron ptychography.
University of Michigan engineers have found that the light in OLED displays comes from nanoscale hotspots—some of which flicker—rather than from a perfectly uniform surface, a behavior that could shorten device lifespans by causing certain areas to carry more current and burn out faster. The studysuggests that these uneven emission patterns may also affect the […]
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a reusable adhesive made from waste polymers that is stronger than commercial glues, works in wet and dry conditions, and bonds materials ranging from wood and glass to metal and plastics. Inspired by mussels’ sticking power, the adhesive uses reversible chemical crosslinkers that […]
MIT physicists have used a new imaging technique to observe terahertz-frequency vibrations—described as quantum “jiggles”—inside a superconducting fluid for the first time, revealing behavior that was previously undetectable. By shining terahertz light, which probes matter differently than optical, infrared or X-ray wavelengths, the team captured inherent quantum motions within the material, opening a new window […]
Argonne National Laboratory has opened its Activated Materials Lab, a radiological facility next to the Advanced Photon Source that lets scientists use an ultrabright X-ray beam to safely examine the inner structure of irradiated metals and nuclear fuels. The new capability allows researchers to see how radiation affects reactor materials in real time, supporting advances […]
