Metallic nanocrystals via an aerosol route
Summary, in English
Mass production of nanocrystals with accurate size control is a central problem in nanotechnology. Aerosol technology offers the possibility to produce nanocrystals with well-controlled composition and size distribution.An aerosol is defined as solid or liquid particles suspended in a gas, and aerosol science and technology has been used since over 60 years, primarily to study the size, shape and composition of airborne particles . For this purpose, tools have been developed, which allow scientists to fabricate and precisely classify particles in the micro- and nanometer size ranges according to size, and to measure their concentration in the carrier gas . The aerodynamic properties of nanoparticles depend almost exclusively on their size and shape and only to a small extent on their mass and composition, which means that the same generic characterization and production tools can be applied to a variety of different materials .Here, I will present a setup of aerosol tools and methods that can be used to generate well-defined metallic nanocrystals.References W.C.
