Prof. Xuanhe Zhao speaks with Amerigo Allegretto of AuntMinnie.com about his work developing a new ultrasound sticker that can measure the stiffness of internal organs and could one day be used for early detection and diagnosis of disease. “Due to the huge potential of measuring the rigidity of deep internal organs, we believe we can use this to monitor organ health,” Zhao explains.
Sublime Systems, an MIT startup, is developing new technology to fully decarbonize the cement manufacturing process, reports Adele Peters for Fast Company. “Instead of using heat to break down rocks for cement, the startup uses chemistry to dissolve them, and then blends the components back together into what it calls ‘Sublime Cement,’” explains Peters. “The process can replace limestone with other minerals, including rocks found at high volumes in industrial waste, so it’s also possible to eliminate the emissions from limestone.”
Researchers from MIT have developed liquid metal printing, a new technique that can be used to quickly 3D print large-scale objects such as furniture, reports Designboom. The researchers say this technique can enable 3D printing, “ten times faster than a comparable metal additive manufacturing process, and the process of melting the metal may be more efficient than some other methods, given that metal is also more accessible with the abundance of scraps that can be recycled,” writes Designboom.
MIT researchers have developed a 3D printing technique called liquid metal printing (LMP) that capable of printing large aluminum parts at least 10 times faster than a comparable metal additive manufacturing process, reports Brian Heater for TechCrunch. LMP “utilizes a bed of 100-micron glass beads to create a structure into which molten aluminum is deposited — a process not entirely dissimilar from injection molding,” explains Heater. “The beads are capable of standing up to the intense temperature, while allowing the heat to quickly dissipate as the metal solidifies.”
Javier Ramos '12, SM '14, co-founder of InkBit, and his colleagues have developed a, “3D inkjet printer that uses contact-free computer vision feedback to print hybrid objects with a broad range of new functional chemistries,” reports Ed Brown for Tech Briefs. “Our vision for Inkbit is to reshape how the world thinks about production, from design to execution and make our technology readily available,” says Ramos. “The big opportunity with 3D printing is how to disrupt the world of manufacturing — that’s what we're focused on.”
Cement production is a climate catastrophe, writes MIT Technology Review’s Casey Crownhart, pumping billions of metric tons of carbon dioxide into the atmosphere. Sublime Systems, a startup founded by MIT Prof. Yet-Ming Chiang and former postdoc Leah Ellis, uses electricity to trigger the chemical reactions that form the building material. Over the past few years, it’s gone from making palm-sized batches to producing 100 tons a year. The next stage is a commercial facility producing tens of thousands of tons of material a year.
ClimateWire reporter John Fialka writes that MIT engineers have developed a new process to convert carbon dioxide into a powder that can be safely stored for decades. “The MIT process gets closer to an ambitious dream: turning captured CO2 into a feedstock for clean fuel that replaces conventional batteries and stores electricity for months or years,” writes Fialka. “That could fill gaps in the nation's power grids as they transition from fossil fuels to intermittent solar and wind energy.”
Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.
MIT researchers have developed a, “new laser-based technique that could speed up the discovery of promising metamaterials for real-world applications,” reports Andrew Corselli for Tech Briefs. The technique “offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials, for the first time,” reports Corselli.
Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.”
MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.
Researchers from MIT and elsewhere have developed a new 3D printing process that “allows users to create more elastic materials along with rigid ones using slow-curing polymers,” reports Tony Ho Tran for the Daily Beast. The researchers used the system to create a, “3D printed hand complete with bones, ligaments, and tendons. The new process also utilizes a laser sensor array developed by researchers at MIT that allows the printer to actually ‘see’ what it’s creating as it creates it.”
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.”
MIT researchers have developed a new programmable, shape-changing smart fiber called FibeRobo that can change its structure in response to hot or cold temperatures, reports Andrew Paul for Popular Science. “FibeRobo is flexible and strong enough to use within traditional manufacturing methods like embroidery, weaving looms, and knitting machines,” writes Paul. “With an additional ability to combine with electrically conductive threads, a wearer could directly control their FibeRobo clothing or medical wearables like compression garments via wireless inputs from a controller or smartphone.”
President Biden has awarded Prof. Emeritus Subra Suresh ScD '81, the former dean of the MIT School of Engineering, the National Medal of Science for his “pioneering research across engineering, physical sciences, and life sciences,” reports Alexa Gagosz for The Boston Globe. Prof. James Fujimoto '79, SM '81, PhD '84, research affiliate Eric Swanson SM '84, and David Huang '85, SM '89, PhD '93 were awarded the National Medal of Technology and Innovation, “the nation’s highest award for technical achievement.”
