Researchers at MIT have “created a stretchable color-changing material based on how nature often reflects color,” reports Nicole Estaphan for WCVB’s Chronicle. “As you stretch it, these embedded nanostructures change size,” explains graduate student Benjamin Miller, “which in turn changes the color of light that comes back. We are making an elastic, squishy version of the sort of thing you find in nature.”
Prof. Emeritus Donald Sadoway and his colleagues have developed a safer and more cost-effective battery to store renewable energy, reports David Abel for The Boston Globe. The battery is “ethically sourced, cheap, effective and can’t catch fire,” says Sadoway.
Researchers from MIT and elsewhere have developed a new cost-effective battery design that relies on aluminum ion, reports Robert F. Service for Science. “The battery could be a blockbuster,” writes Service, “because aluminum is cheap; compared with lithium batteries, the cost of materials for these batteries would be 85% lower.”
Researchers at MIT have developed a battery that uses aluminum and sulfur, two inexpensive and abundant materials, reports Alex Knapp and Alan Ohnsman for Forbes. “The batteries could be used for a variety of applications,” write Knapp and Ohnsman.
MIT researchers have created a new battery using inexpensive and plentiful materials to store and provide power, reports Tony Ho Tran for The Daily Beast. “The study’s authors believe that the battery can be used to support existing green energy systems such as solar or wind power for times when the sun isn’t shining or the air is still,” writes Tran.
Prof. Donald Sadoway and his colleagues have developed a battery that can charge to full capacity in less than one minute, store energy at similar densities to lithium-ion batteries and isn’t prone to catching on fire, reports Alex Wilkins for New Scientist. “Although the battery operates at the comparatively high temperature of 110°C (230°F),” writes Wilkins, “it is resistant to fire because it uses an inorganic salt that can’t burn as its electrolyte, the material that allows charge to flow inside a battery.” Sadoway explains that “this is a totally new battery chemistry."
Gradiant, an MIT startup founded by Anurag Bajpayee PhD ’12, S.M. ‘08 and Prakash Govindan PhD ’12, has developed an energy efficient system that purifies water by mimicking natural rainfall cycles, reports Aaron Pressman for The Boston Globe. “Nature has the advantage of having all the surface area of the oceans available freely and a free source of energy from the sun,” Govindan said. “We have to engineer this into a compact, highly efficient, and energy-efficient industrial device.”
MIT researchers have developed a transparent, degradable medical dressing that could be used to help gut wounds heal more quickly and efficiently without leaking bacteria, reports Alex Wilkins for New Scientist. The researchers “designed their dressing to work like duct tape, which is only sticky on one side,” writes Wilkins. “Once it covers the wound, it quickly forms a hydrogel, an adhesive layer that can help the wound to heal.”
Fortune reporter Nicole Gull McElroy spotlights how the MIT Innovation Initiative and the Sloan School of Management are opening Innovation HQ, a 50,000 square foot space that will house a cross-disciplinary innovation and entrepreneurship lab. “Innovation HQ will offer students, alumni, faculty and staff a place to work, collaborate and create with six departments, lab space, an innovator’s lounge and a new space for music and arts innovation called Voxel Lab,” writes McElroy.
Wired reporter Max G. Levy writes that MIT researchers have developed a glue inspired by barnacles that can adhere to wet tissues and stop bleeding in seconds. “For us, everything is a machine, even a human body,” says research scientist Hyunwoo Yuk. “They are malfunctioning and breaking, and we have some mechanical way to solve it.”
TechCrunch reporter Brian Heater writes about Inkbit, a CSAIL spinout, which is developing self-correcting 3D printing technology. “Its primary differentiator from the slew of existing 3D printers is a vision and AI system designed to identify and correct mistakes during the printing process,” writes Heater.
LiquiGlide, an MIT startup, has announced several new partnerships aimed at developing sustainable, zero-waste packaging solutions, reports Janelle Nanos for The Boston Globe. “LiquiGlide wants to fix one of life’s longstanding frustrations: trying to squeeze out the end of a toothpaste tube,” writes Nanos. “Since it’s often difficult to empty out sticky pastes, gels, and creams, hundreds of millions of dollars worth of those substances are discarded annually, still stuck to the insides of their containers.”
Prof. Kripa Varanasi speaks with Boston 25 reporter Jim Morelli about a food-safe coating, called LiquiGlide, that makes it possible to squeeze every drop out of containers of items like ketchup and toothpaste. “It’s a universal kind of a problem,” Varanasi says. “The interface between the liquid and the solid is what makes these products stick to containers.”
Gizmodo reporter Andrew Liszewski writes that LiquiGlide, an MIT startup, is working with Colgate to introduce a “new recyclable toothpaste container that leverages LiquiGlide so that every last drop of the product can be squeezed out with minimal effort.”
Writing for Scientific American, Carolyn Barber spotlights how researchers from MIT are developing cheap, fast and easy to use diagnostics for Covid-19 that can deliver results in minutes. “They are called lateral flow assays, but manifestly they are paper-strip tests that have an antibody embedded on filter paper,” writes Barber. “If a saliva sample has coronavirus present, the antibody will bind that viral antigen, turning the test positive, much like a pregnancy test works.”
