One of the great stories of invention concerns the building of the first laser, by Ted Maiman at Hughes Research. Less well known is the story about how that invention triggered a very-high-stakes, three-way race to build a semiconductor laser, among General Electric, IBM, and MIT's Lincoln Lab. https://lnkd.in/gpin4NrP

Researchers at Oak Ridge National Laboratory explain the most promising approaches to building a high-performance electric-vehicle motor that does not use rare earth elements.

If the transition to a new energy regime isn't adeptly managed, warns Robert Charette, we could wind up with "a dystopian grid where energy costs are high and reliability is poor, decarbonization progress is stalled, and the economic gains that have been made over the last century are at risk." In a conversation with Deepak Divan of Georgia Institute of Technology, the two experts chart a path forward that would avoid the pitfalls https://lnkd.in/ek8xY967

Budding engineer Ananya Yanduru requested for #IEEE USA’s MOVE emergency relief truck to visit her high school. She and her classmates learned about the equipment survivors rely on, including satellite Internet access and IP phone service.

A relatively new family of superconducting materials, the lanthanum hydrides, is fascinating researchers with their bizarre magnetic properties and astonishingly high superconducting "transition" temperatures. One of them can superconduct at -23 degrees C—the highest yet observed in a superconducting material https://lnkd.in/eB3XPyPV

Meet the members shaping the future of #IEEE! Get to know Deepak Mathur, Saifur Rahman, and Aylin Yener.

Gig workers aren’t the only people who should be paying attention to algorithmic management -- their battles are the leading front in the larger war for workplace rights.

Tsunenobu Kimoto, recipient of the 2024 IEEE Andrew S. Grove Award, is responsible for innovations in silicon carbide semiconductor devices, which have had an incalculable impact on modern technology.

Almost all electric vehicles use rare-earth permanent-magnet synchronous motors, because these are the highest-performing motors by any metric. But mining and processing rare earth elements generally comes with environmental consequences, so researchers all over the world are trying to build powerful, compact motors that don't use rare earths. In this feature, three top researchers from Oak Ridge National Laboratory survey some of the best results and projects so far. https://lnkd.in/eZaZFgY6
