Nano-science looks at nano-interfaces and nano-junctions, atomic and molecular manipulation of adsorbates, properties of self assembled films and quantum transport in nano-structures. Understanding of these phenomena at the nano-scale is of great importance for both science and technology. Computations for the Nano-Scale is the first book to present the state of the art of the theory of nano-science and some related experiments. It assembles contributions from leading experts who met for a NATO Workshop in Aspet, France, October 12--16, 1992.
