Nanoscale hotspots in OLEDs may shorten their lifespans in phones, TVs

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 […]

Tough, reusable adhesive can glue a variety of materials

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 […]

Terahertz microscope reveals the motion of superconducting electrons

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 […]
