The National Science Foundation (NSF) has selected MIT to establish and lead a new Materials Research Science and Engineering Center (MRSEC) focused on materials technologies for medical imaging, sustainable metals production, and next-generation semiconductors, according to an NSF announcement released July 30.
Expected to provide $18 million in research funding over six years, the award brings together 16 research groups from nine departments across four institutions, including five MIT departments, three collaborating universities, and a teaching hospital. The award is pending MIT's negotiation of a formal research agreement with the NSF.
The MIT Materials Research Science and Engineering Center will be directed by Associate Professor Rafael Jaramillo of the Department of Materials Science and Engineering (DMSE), with Professor Caroline Ross of DMSE serving as associate director. The center will be housed administratively within the MIT Materials Research Laboratory.
The center will have two main research thrusts. One will engineer specialized materials to advance X-ray detectors used in medical imaging, potentially leading to better cancer diagnosis, lower radiation exposure, and improved industrial and security imaging. The other will explore high-temperature sulfur-based molten materials to transform how metals and semiconductors are made, opening a path to more efficient metal production, improved access to critical materials, and new thin-film semiconductor technologies.
The expected funding will also support a new shared laboratory for testing magnetic materials and materials under extreme conditions, managed by MIT.nano. This facility will be available to academic and industry users, expanding the nationwide portfolio of NSF-supported research facilities.
"The long-term goal is for the broader materials and engineering community to see the disruptive potential of bringing researchers together across disciplines to solve complex challenges," says Jaramillo, the Stavros V. Salapatas Career Development Professor of Materials Science and Engineering. "And that includes specifically in medical diagnostics and metals production, where entirely new things will be possible that aren't considered possible today."
A legacy of collaboration
The selection of MIT's MRSEC is part of a $108 million NSF investment in six research centers that will explore a range of topics, including artificial intelligence-driven experimental laboratories and hybrid quantum materials that combine light and matter. NSF's MRSEC program brings together interdisciplinary teams of researchers to push the boundaries of materials science and engineering and tackle complex scientific challenges.
The MIT center builds on nearly 60 years of interdisciplinary materials research at the Institute, extending a legacy that began with U.S. Department of Defense-supported laboratories in the 1960s and continued through NSF-funded centers in subsequent decades. Past MRSEC investments helped build research communities that enabled MIT centers of excellence such as the MIT Microphotonics Center and the Microsystems Technology Laboratories.
"We were inspired to continue that legacy of collaborative research in materials science," Jaramillo says. "It's mainly the mode of working - the mode of working in a very intentional way as a team across disciplinary boundaries and having this program that brings people together."
MIT departments involved in the MRSEC include DMSE; Chemistry; Chemical Engineering; Earth, Atmospheric and Planetary Sciences (EAPS); and Physics. Collaborating institutions identified in the MRSEC proposal are Yale University, the University of California at Santa Barbara, and the Department of Radiology at Massachusetts General Hospital and Harvard Medical School.
The first research group will focus on re-engineering scintillators - materials that convert X-rays into visible light - at the nanoscale, with the goal of improving resolution, speed, and energy sensitivity.
"My vision for that is really Marin and JJ's vision. So I'm basically cheerleading for them," Jaramillo says, referring to optical materials experts Professor Marin Soljačić of Physics and Professor Juejun Hu of DMSE, who are expected to lead the effort.
The second group is closer to Jaramillo's own research in semiconductor and advanced electronic materials. It seeks to develop a deeper understanding of high-temperature sulfur-based liquids to improve the yield and efficiency of producing critical metals such as copper. Expertise in these types of materials has become increasingly rare in U.S. academia, Jaramillo says, and one goal of the center is to rebuild that capability at MIT. "I'm very excited about that being a new intellectual center of gravity."
Telling stories about materials
Beyond research, the center is also expected to develop outreach activities highlighting the importance of materials science in society, particularly in the Boston region, where Jaramillo said industries need more workers with backgrounds in materials processing.
"For example, our community colleges don't offer it," Jaramillo says. "If you were looking at a community college in Michigan, everyone would know what materials science is."
One initiative, DISASTER! - "with all caps and an exclamation mark," Jaramillo says - will tell stories of real-world catastrophes and the materials failures that contributed to them.
A major part of materials science over the last century has been understanding why things fail, Jaramillo says. "It's also a tremendous foot in the door for introducing the field. Because frankly, 'if it bleeds, it leads.' If you have giant disasters, then suddenly people are like, 'Why did the bridge fail?'"
The program will encourage MIT undergraduates to research and tell these stories, illustrating how forensic materials science has helped prevent future failures.
Among the examples Jaramillo cited are the rivets used to assemble the RMS Titanic, whose impurities made the rivets more brittle in the freezing North Atlantic, and the crashes of the world's first commercial jetliner, the de Havilland Comet, which revealed the dangers of metal fatigue.
"There are so many other stories that need to be told around how a material failed," Jaramillo said. "It really cost people money and time and lives. And then through forensic materials science, we understood why it failed and we avoided future failures."
The MRSEC team is planning to stage public outreach events at the MIT Future Fest.
Looking ahead six years, Jaramillo hopes the center will have become a self-sustaining hub for materials research.
"I hope that we will have rebuilt the muscle memory to come together in an interdisciplinary way around materials science, and that it should have a bit of a self-sustaining element to it. I hope that we then compete successfully for the next center, and lay the groundwork for the next 60 years."
MIT Research Administration Services supported the MRSEC proposal development through its Research Development team, which specializes in providing substantive assistance for large and complex research proposals, and in supporting early-career faculty.
MIT faculty expected to be involved in the MRSEC are Rafael Jaramillo, Caroline Ross, Juejun Hu, and Antoine Allanore of DMSE; Moungi Bawendi of Chemistry; Martin Bazant of Chemical Engineering; Nicole Nie and Shuhei Ono of EAPS; and Marin Soljačić, Riccardo Comin, Nuh Gedik, and Long Ju of Physics.
