A multidisciplinary team of scientists has used the National Synchrotron Light Source II (NSLS-II), a U.S. Department of Energy (DOE) Office of Science User facility located at the DOE's Brookhaven National Laboratory, to investigate how high-temperature molten salts corrode metal alloys. The group found a novel approach for using molten salts to create porous metallic materials with microscopic networks of voids and metal ligaments, which could have applications in a variety of fields, such as energy storage and sensing. Their work also supports the development of molten salt reactors (MSRs), a technology that could produce safer, cheaper, and more environmentally sustainable nuclear power.
