On the nanometric scale (one billionth of a metre), materials can feature new properties. A French team together with an Austrian one recently took an important step forward by mapping one of these properties for the first time in 3D. Imagine a cube on which light is projected by a flashlight. The cube reflects the

Extremely well studied and understood, the electrical properties of salts were first theorized in 1834. Now,

Researchers at the Georgia Institute of Technology have uncovered an innovative way to tap into the over-capacity of 5G networks, turning them into “a wireless power grid” for powering Internet of Things (IoT) devices that today need batteries to operate. The Georgia Tech inventors have developed a flexible Rotman lens-based rectifying antenna (rectenna) system capable,

ORLANDO, March 25, 2021 – Early screening can mean the difference between life and death in a cancer and disease diagnosis. That’s why University of Central Florida researchers are working to develop a new screening technique that’s more than 300 times as effective at detecting a biomarker for diseases like cancer than current methods. The

When we grow crystals, atoms first group together into small clusters – a process called nucleation. But understanding exactly how such atomic ordering emerges from the chaos of randomly moving atoms has long eluded scientists. Classical nucleation theory suggests that crystals form one atom at a time, steadily increasing the level of order. Modern studies
