Inert Gas Condensation
We are presently using an inert gas condensation (IGC) technique to produce nanoparticles of silver, iron, and copper. The technique is based on evaporation of the metal under a high partial pressure of an inert gas. With IGC, we are able to produce particles that range in size from 10 nm to 100nm. Some of the applications that we are investigating include the use of silver and copper nanoparticles in nanofluids for thermal conductivity enhancement; the use of silver dispersed in polymeric fibers as an antibacterial agent; and the use of iron in magnetic fluids.
