Researchers at MIT have developed a “new type of transistor using semiconductor nanowires made up of gallium antimonide and iridium arsenide,” reports Alex Knapp for Forbes. “The transistors were designed to take advantage of a property called quantum tunneling to move electricity through transistors,” explains Knapp.
Researchers at MIT have demonstrated “fully 3D-printed semiconductor-free resettable fuses,” reports Jesse Allen for Semiconductor Engineering. “The researchers plan to further develop the technology to print fully functional electronics and aim to fabricate a working magnetic motor using only extrusion 3D printing,” writes Allen.
Prof. Admir Masic speaks with New York Times reporter Amos Zeeberg about his research studying the benefits of lime clasts – a material used in ancient Roman infrastructure. According to Masic’s research, “these lime clasts were actually reservoirs of calcium that helped fill in cracks, making the concrete self-healing,” writes Zeeberg. “As cracks formed, water would seep in and dissolve the calcium in the lime, which then formed solid calcium carbonate, essentially creating new rock that filled in the crack.”
Seonghoon Woo PhD '15, Jongwon Choi PhD '17, Young Suk Jo SM '13, PhD '16, and Hyunho Kim SM '14, PhD '18 have co-founded Amogy – a startup company that is using ammonia produced by renewable energy as a carbon-free way to fuel a tugboat, report Jennifer McDermott and Michael Hill for The Associated Press. “Without solving the problem, it’s not going to be possible to make the planet sustainable,” says Woo. “I don’t think this is the problem of the next generation. This is a really big problem for our generation.”
Forbes reporter Amy Feldman spotlights the work of Prof. Yet-Ming Chiang, who has used his materials science research to “build an array of companies in areas like batteries, green cement and critical minerals that could really help mitigate the climate crisis.” Feldman notes that “as the climate crisis has become increasingly urgent, Yet-Ming Chiang’s ability to spin out companies from his research offers hope.”
WBUR’s Erin Trahan highlights how the MIT Museum will be presenting selections from the Woods Hole Film Festival with “monthly titles that broadly encompass ‘science on screen.’” Trahan notes that on “Oct. 26, the MIT Glass Lab co-presents a documentary about a master Italian glass blower, ‘Sono Lino.’ Erik Demaine, MIT professor of computer science, and Peter Houk, MIT instructor and artistic director of the Glass Lab, will introduce the film.”
MIT scientists have “observed and captured images of a rare ‘edge state’ in ultracold atoms,” reports Rupendra Brahambhatt for Interesting Engineering. “Using these findings, they can learn to achieve and harness the edge states of electrons in different materials,” notes Brahambhatt. “This breakthrough in the field of quantum physics could lead to the discovery of practically infinite energy sources.”
Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '22 founded AgZen, a company aimed at reducing pesticide use by employing a feedback-optimized spraying system, reports Steven Savage for Forbes. Savage notes that for the researchers behind AgZen, “MIT turned out to be a good place to work on the specific imaging technology and on the AI needed to translate that into a practical solution for farmers.”
Prof. Moungi Bawendi, a recipient of the 2023 Nobel Prize in Chemistry, speaks with Nobel Prize Conversations host Adam Smith about the joys of visualizing quantum mechanics, the inspiration for his Nobel-prize winning work and his love of music. “Being in a place like MIT and being exposed to engineering and other scientific fields and medicine across the river and Harvard Medical School and a lot of startups around here, you really are exposed to so many things that are so interesting and I love that,” says Bawendi. “Those things give me ideas of how to go back to the lab and take different directions.”
MIT scientists have discovered that metals become harder when heated under certain conditions, reports Isabelle Dume for Physics World. In an interview, Prof. Christopher Schuch says by bombarding metals with tiny bits of sapphire small enough to avoid shock waves, “the result is a clean and quantitative set of data that clearly reveals the counterintuitive ‘hotter-is-stronger’ effect.”
MIT startup, 24M, has designed an EV battery with a range of 1,000 miles on a single charge, reports Adele Peters for Fast Company. “The extra-long range also can help the car’s battery last much longer,” explains Peters. “If you use a rapid charger to fully charge a battery, it can damage the battery, meaning it won’t last as long. Because it has such a long range, the new battery should rarely need a full rapid charge.”
TechCrunch’s Tim De Chant has a look at MIT spinoff SiTration, which has developed a new process to reat mining wastewater and filter our critical minerals using silicon. “SiTration’s filters are built on the same style of wafers that are used to make computer chips and solar panels, though using a cheaper grade of silicon,” De Chant explains.
Researchers at MIT have created a noise-blocking sheet of silkworm silk that could “greatly streamline the pursuit of silence,” reports Andrew Chapman for Scientific American. “The silk sheet, which is enhanced with a special fiber, expands on a technology also found in noise-canceling headphones,” explains Chapman. “These devices create silence by sampling the ambient noise and then emitting sound waves that are out of phase with those in the environment. When the ambient and emitted waves overlap, they cancel each other out.”
For the first time ever, researchers at MIT have observed electrons form “fractional quasiparticles without enabling the influence of a magnetic field,” reports Daniel Garisto for Quanta Magazine. This discovery “may carry the seeds of long-sought quasiparticles with stable memories that could underpin a new and powerful approach to quantum computing.”
Researchers at MIT have developed a fiber capable of suppressing sound that is made up of “silk, canvas and other common materials,” reports Charlie McKenna for MassLive. “The silk is barely thicker than human hair and is made by heating the materials and drawing them into a fiber,” explains McKenna. “Since each material flows at the same temperature, they can be pulled into a fiber while maintaining their structure.”
