The Materials Research Facilities Network (MRFN) has recently been established and is currently in operation at ca. 50% of MRSEC sites. The goal of the MRFN is to maximize the usage of MRSEC facilities and is directed towards the efficient and strategic development of materials characterization within the United States. By providing easy access through its wide geographical distribution to small and large universities not in the MRSEC program, the MRFN will substantially contribute to the education and mentoring of a wide diversity of students and further promote collaborative research in materials.
