Researchers from North Carolina State University and the Air Force Research Laboratory have discovered that a technique designed to coat nickel nanoparticles with silica shells actually fragments the material – creating a small core of oxidized nickel surrounded by smaller satellites embedded in a silica shell. The surprising result may prove useful by increasing the surface area of nickel available for catalyzing chemical reactions.
