  • Scientists turn scrap car aluminum into high-performance metal for new vehicles
    Scientists at Oak Ridge National Laboratory have created a new aluminum alloy called RidgeAlloy that can turn contaminated car-body scrap into strong structural vehicle parts. Normally, impurities introduced during recycling make this scrap unsuitable for high-performance applications. RidgeAlloy overcomes that challenge, enabling recycled aluminum to meet the strength and durability standards required for modern vehicles. […]
  • Electrons catapult across solar materials in just 18 femtoseconds
    Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 femtoseconds, researchers at the University of Cambridge observed electrons blasting across a boundary in a single burst, far faster than long-standing theories predicted. Instead of […]
  • Record-breaking photodetector captures light in just 125 picoseconds
    A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a signal in just 125 picoseconds, making it the fastest pyroelectric detector ever built. The breakthrough could power next-generation multispectral cameras used in medicine, agriculture, and space-based sensing.
  • For the first time, light mimics a Nobel Prize quantum effect
    Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps—just like electrons do in powerful magnetic fields. Because these steps depend only on nature’s fundamental constants, they could become a new gold standard for […]
  • Scientists confirm one-dimensional electron behavior in phosphorus chains
    For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron behavior. Using advanced imaging and spectroscopy techniques, they separated the signals from chains aligned in different directions to reveal their true nature. The findings suggest that squeezing the chains closer together could trigger a dramatic shift from semiconductor to […]
  • A tiny light trap could unlock million qubit quantum computers
    A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing many qubits to be read at once. The team has already demonstrated working arrays with dozens and even hundreds of cavities. The approach could eventually support massive quantum networks with […]
