Using the Aerosol Through Plasma (ATP) method in conjunction with simple chemical techniques a variety of complex and novel nanoparticle architectures were created. A TP was used to make metal-core/carbon shell nanoparticles (ca. 50 nm diameter) of SnlCarbon and AI/Carbon. These have, respectively, potential for application as battery anode (for hybrid and electric vehicles) and high energy fuel In one example of post processing, the Sn-core/carbon-shell material is treated in acidic solution and yields a true nano-sized hollow carbon shell. These shells have potential application as catalyst supports, gas storage, a neutral buoyancy material for applications as varied as proppants, and slow release capsules for pharmaceutical or agricultural applications. A different set of post-A-T-P processes were used to make three layer nanoparticles with a metal core, graphite inner shell and ceramic outer shell. This method extends the range of achievable nanoparticles architectures, hence enabling new applications.
