Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...
Engineers have developed a new way to 3D-print liquid and solid materials together, potentially leading to more dynamic and useful products -- from robots to wearable electronic devices. Imagine a ...
For more than a century, schoolbook physics has divided matter into neat categories like solid, liquid, gas, and plasma. A ...
