Shaping the flow characteristics of a proportional directional valve
Hydraulic systems are mainly used where there is a need to transfer very heavy loads, even at high speeds. Hydraulic systems can be used for both position control and force control (e.g. in hydraulic presses). Indispensable elements of any…

One Tiny Structure Just Broke a Fundamental Rule of Optics
Scientists have broken a fundamental limit in optics by decoupling angle and wavelength using innovative bilayer metagratings. Wavelength and the direction in which light travels (angle) are two essential characteristics that define how light…

Wave or Particle? Physicists Crack a 50-Year-Old Quantum Puzzle
Stevens’ team harnesses both the “wave-ness” and “particle-ness” of quantum objects to develop a groundbreaking imaging technique. Over the past century, quantum mechanics has dramatically reshaped our view of the universe, uncovering a…

Why broken crystals are stronger
Crystals are known far and wide for their beauty and elegance. But even though they may appear perfect on the outside, their microstructure can be quite complicated, making them difficult to model mathematically.
But there are people rising to…
