Abstract:
Graphite/carbon encapsulated metal (GEM) nanoparticles (Fig.1) not only provides an opportunity to study dimensionally confined systems, but also could be used in many nanotechnology applications, e.g. recording media, nano-sized wheel bearings, etc. Unlike other metal nanoparticles, the material has a great advantage that it is protected by graphitic outer shells and therefore can survive in severe environments, such as in a strong acid.
