A few years ago, Sammy Tin, a professor of materials engineering at the Illinois Institute of Technology reached out to Northwestern University with a specific request. Tin was studying advanced polycrystalline nickel-base superalloys and needed access to Northwestern University's state-of-the-art equipment at its Center for Atom-Probe Tomography. Northwestern University is part of NSF's Materials Research Facilities Network (MRFN) -- a nationwide partnership designed to enhance access to the latest equipment and expertise in the materials research and engineering field. As part of his research, Tin collaborated with researchers in China as well as others in the U.S., and the team published their findings last year.
