Chemical engineering

Science reporter Jennifer Sills asked scientists to answer the question: “Imagine that you meet all of your research goals. Describe the impact of your research from the perspective of a person, animal, plant, place, object, or entity that has benefited from your success.” Xiangkun (Elvis) Cao, a Schmidt Science Fellow in the MIT Department of Chemical Engineering, shares his response from a photon’s perspective. “I am a photon,” writes Cao. “I started my journey entangled with my significant other at the beginning of the Universe. In the past, humans couldn’t understand me, but then physicists created a quantum computer. At last, I have been reunited with my life partner!”

Milena Pagán '11 speaks with Boston.com reporter Linda Laban about re-opening her bagel shop, Rebelle Bagels, in Kendall Square. Pagán, who earned a degree in chemical engineering before diving into the culinary world, explains that she felt it was a natural transition from engineering to food. “It’s not a traditional path, but they do have a lot in common,” Pagán explains. “Making bagels feels a lot like engineering.”

Prof. Gregory Rutledge speaks with The Ringer reporter Claire McNear about the science behind nanofibers and whether it's possible to create ultrathin and ultrastrong nanofibers that are invisible to the human eye, as shown in the science fiction series “3 Body Problem.” Rutledge explains that: “Given that a human hair is about 50 micrometers in diameter, a fiber 100 times smaller would be about 500 nanometers in diameter. Such fibers are routinely made by electrospinning, as well as by a couple of other technologies. Metal wires can also be drawn that small.”

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.”

Priyadarshi Panda PhD '11 – founder of International Battery Company, a startup developing lithium-ion battery cells for electric vehicles – is working to “bridge the demand-supply gap in the growing EV market in India,” reports Jagmeet Singh for TechCrunch. “There is a lot of demand in the Indian market, which is satisfied through imports right now,” says Panda. “No cells are being manufactured in India. So, we want to participate in that journey in India.”

Forbes contributor William Haseltine spotlights how MIT researchers developed a biosensor ingestible capsule that can gather and transmit information on a patient’s condition to a physician. Haseltine notes that “aside from respiratory and heart rate monitoring, future applications for the pill could come from alterations in its design, leading to other avenues of health monitoring. These may include digestive health, blood sugar monitoring and cancer cell detection.” 

Researchers from MIT and elsewhere are developing an electronic pill that can “measure heart rate, breathing rate and core temperature – from inside a human stomach,” reports Celia Ford for Wired. “We have a solution that’s relatively simple and enables access broadly,” says Prof. Giovanni. “I think that can be really transformative.”

Prof. Brad Olsen speaks with Slate reporter Anna Gibbs about the use of bio-based polymers in place of plastics. Olsen says “for this approach to take off, though, the cost of bio-based polymers will need to go down. When you’re producing something that’s identical but charging more, really what you’re charging more for is the fact that it’s made with green carbon.” 

Forbes reporter Nancy Wang spotlights Tara Bishop '97 and Eileen Tanghal '97, co-founders of Black Opal Ventures, a venture capital firm focused on health tech. “Tara and Eileen’s story at Black Opal Ventures is a testament to how diversity and innovation can disrupt traditional landscapes,” writes Wang. “Their pioneering strategies and investments herald a new era for healthcare venture capitalism, where diversity and technology converge to create a more inclusive and impactful future.”

Researchers from MIT and elsewhere have developed a swallowable “technopill” that can monitor vital signs from inside the body, reports Dennis Thompson for HealthDay. “The ability to facilitate diagnosis and monitor many conditions without having to go into a hospital can provide patients with easier access to healthcare and support treatment,” says Prof. Giovanni Traverso.

New Scientist reporter Alice Klein writes that MIT researchers have developed an ingestible electronic device that “can measure your breathing and heart rate from inside your gut [and] could potentially diagnose sleep apnea and even detect opioid overdoses.” The device could one day allow “people to be assessed for sleep apnea wirelessly and cheaply while at home.”

Researchers at MIT and elsewhere have developed a swallowable electronic capsule that can be used to help diagnose sleep apnea and other sleep disorders, reports Ian Randall for Newsweek. “Conventional laboratory and home sleep studies require the patient to be attached to many different sensors,” says Prof. Giovanni Traverso. “As you can imagine, trying to sleep with all of this machinery can be challenging. [The] ingestible capsule just requires that the patient swallow the vitamin-sized pill. It's easy and unobtrusive and can accurately measure both respiratory rate and heart rate while the patient sleeps."

Milena Pagán '11 speaks with Boston Globe reporter Kara Baskin about bringing her Providence-based bagel shop, Reblle, to Kendall Square. “We started the process to move a store to Cambridge about two years ago” says Pagán. “This has really been a long time in the making, to find the right space and to work out a deal. But we’re in a really cool building. We have tenants upstairs. There’s a park across the street that reminds me in a lot of ways of the neighborhood where Rebelle is right now. And being close to MIT is such a dream. That place has really good juju for me, so I’m really excited about it.

Institute Prof. Robert Langer speaks with Freakonomics host Stephen Dubner about his approach to failure and perseverance in his professional career. Langer recalls how despite early failures with developing new drug delivery methods, “I really believed that if we could do this, it would make a big difference in science, and I hoped a big difference in medicine.”

Milena Pagán '11 bringing her Providence-based bagel shop, Rebelle, to Kendall Square this winter, reports Kara Baskin for The Boston Globe. “Pagán was a 2023 Best Chef: Northeast James Beard semifinalist for her Puerto Rican café, Little Sister, also based in Providence,” writes Baskin.
