Very small particles are able to show astonishing properties. For example, gold atoms can be combined like strings of pearls, while nanoparticles can form one-, two- and three-dimensional layers. These assemblies can be used, for instance, as semiconductors, but other electronic as well as optical properties are possible. An introduction to the booming field of "nanoworld" or "nanoscience", from fundamental principles to their use in novel applications. With its clear structure and comprehensive coverage, backed by numerous examples from recent literature, this is a prime reference for chemists and materials scientists working with and developing nanoparticle systems. A bestselling title in its second edition. A must-have reference for chemists and materials scientists.
