The yolk-shell nanoparticles are made by coating sulfur with a nanoporous layer of hard titanium dioxide, and then using a solvent to dissolve away some of the sulfur while leaving the shell in place.
SLAC programs explore the ultimate structure and dynamics of matter and the properties of energy, space and time -- at the smallest and largest scales, in the fastest processes and at the highest energies -- through robust scientific programs, excellent accelerator-based user facilities and valuable partnerships. Located in Menlo Park, California, SLAC is operated by Stanford University for the U.S. Department of Energy Office of Science.
