Researchers have observed three-dimensional magnetic vortex rings in a real-world magnetic material for the first time. Contrary to theoretical predictions, these rings – which are spin configurations ...
Rocket engines are known for one thing above all else, and that’s getting hot. It’s this very property that makes them such a challenge to build and run from a materials engineering standpoint. It’s ...
Researchers 3D-printed a low-cost and efficient device that generates twisting light beams with orbital angular momentum and features integrated gain-filtering. WASHINGTON — Researchers have developed ...
