Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”

MIT researchers have successfully figured out how to trap tiny electrons in a three-dimensional crystal prison, reports Jess Thomson for Newsweek. The researchers hope that “the flat band properties of the electrons in these crystals will help them to explore new quantum states in three-dimensional materials,” Thomson explains, “and therefore develop technology like superconductors, supercomputing quantum bits, and ultraefficient power lines.”

Writing for The Hill, Randolph Kirchain and Hessam AzariJafari of the MIT Concrete Sustainability Hub emphasize the importance of encouraging development of building materials with low lifetime carbon impact. “When we choose a construction material without considering its life cycle impacts,” they write, “we not only miss an opportunity to reduce use phase and end-of-life emissions, but we can unintentionally worsen them.”

Ambri, an MIT startup that has developed a liquid-metal battery that can be used for grid-level storage of renewable energy, has announced that it is months away from delivering its first battery to a customer, reports Jacob Wycoff for CBS Boston. "We want to have a battery that can draw from the sun even when the sun doesn't shine," said Prof. Donald Sadoway of the inspiration for Ambri’s battery.

Prof. Donald Sadoway is the recipient of the 2022 European Inventor Award for his work in liquid metal batteries, reports WBUR. “MIT says the battery could enable the long-term storage of renewable energy,” says WBUR.

MIT researchers have designed a completely flat wide-angle lens that can produce clear, 180-degree images, reports Darrell Etherington for TechCrunch. “The engineers were able to make it work by patterning a thin wafer of glass on one side with microscopic, three-dimensional structures that are positioned very precisely in order to scatter any inbound light in precisely the same way that a curved piece of glass would,” writes Etherington.

Tanzina Vega of The Takeaway speaks with WGBH reporter Kirk Carapezza about how MIT is training workers in the field of integrated photonics to help fill a labor gap. “MIT has been working with community college students, helping them get internships,” explains Carapezza, “and trying to simultaneously develop the technology and train people how to use it.”

Scientific American reporter Prachi Patel writes that a new study by Prof. Elsa Olivetti found that demand for cobalt, which is critical to electric vehicle batteries, could soon outstrip supply. “The best lithium battery cathodes [negative electrodes] all contain cobalt, and its production is limited,” Olivetti explains.
