Nanostructured composites basic properties

The bottom-up approach represents the concept of constructing a nanomaterial from basic building elements, that is, atoms or molecules. This approach illustrates the possibility of creating materials of SEs with exactly the properties desired. The second approach, the top-down method, involves restructuring a bulk material in order to create a nanostructure. Inert gas condensation, considered a bottom-up technique, was the first method used to intentionally construct a nanostructured material, and has become a widespread means of producing nanostructured metals, alloys, intermetallics, ceramic oxides, and composites...
