- A strange in-between state of matter is finally observedWhen materials become just one atom thick, melting no longer follows the familiar rules. Instead of jumping straight from solid to liquid, an unusual in-between state emerges, where atomic positions loosen like a liquid but still keep some solid-like order. Scientists at the University of Vienna have now captured this elusive “hexatic” phase in real […]
- New catalyst makes plastic upcycling 10x more efficient than platinumScientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide’s atoms are arranged at extremely high temperatures, researchers discovered a specific form that can rival platinum in key chemical reactions, including turning carbon dioxide into useful fuels and chemicals. Even more […]
- Engineers just created a “phonon laser” that could shrink your next smartphoneEngineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can produce ultra-fast surface waves that already play a hidden role in smartphones, GPS systems, and wireless tech. Unlike today’s bulky setups, this single-chip device could deliver […]
- An old jeweler’s trick could change nuclear timekeepingA team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years of work with delicate crystals — but far more efficiently. These clocks could be vastly more precise than current atomic clocks and work […]
- Critical minerals are hiding in plain sight in U.S. MinesResearchers found that U.S. metal mines already contain large amounts of critical minerals that are mostly going unused. Recovering even a small fraction of these byproducts could sharply reduce dependence on imports for materials essential to clean energy and advanced technology. In many cases, the value of these recovered minerals could exceed the value of […]
- Miracle material’s hidden quantum power could transform future electronicsResearchers have directly observed Floquet effects in graphene for the first time, settling a long-running scientific debate. Their ultrafast light-based technique demonstrates that graphene’s electronic properties can be tuned almost instantaneously. This paves the way for custom-engineered quantum materials and new approaches in electronics and sensing.
