If artificial intelligence (AI) was a car, data would be the fuel. But what if there was no way to ensure that fuel wasn’t full of waste? How would this fuel be filtered, and how would that information reach consumers? Ran Jin, associate professor in the Grado Department of Industrial and Systems Engineering, is determined to fuel AI models in the Manufacturing Industrial Internet with high-quality data.

When superconductors encounter too much current, they can become resistive. Researchers can design microscopic electronic components that use this effect to create a switch, like a transistor. The resulting nanowire superconducting switching devices (called nano-cryotrons, or nTrons) show promise for future superconducting electronics or particle detectors.
