Nanocomposites have been receiving more and more attention given the improvement of synthesis techniques and the availability of powerful characterization techniques. The aim of the book is to introduce nanocomposite materials using a broad range of inorganic and organic solids. Furthermore, it is intended to present recent and not very common developments in especially spectroscopic characterization techniques, including Mössbauer, EXAFS, NMR. This should make the book attractive for a broad range of readers, including chemists and physicists.
