Opis

Clusters of Atoms and Molecules is devoted to physical, chemical, and technological problems of clusters and small particles. In the first part the solvation, charging, and chemistry of free clusters in vacuum is studied, while the second part describes clusters deposited on surfaces, or embedded in gases, liquids or solids. Several technological applications, such as catalysis, photography, coloured glasses, quantum dots, and nanocrystalline materials are discussed. Each contribution is written so as to be easily understandable for newcomers and concludes with the latest results.

O autorze

Clusters of Atoms and Molecules deals with the physics and chemistry of clusters and small particles. It is the first book on this subject and provides an overview of the entire field from solid state physics, to physical chemistry and technology. Each chapter is written by an expert in the field. The authors laid emphasis on a simple introduction readily understandable to undergraduates, and then continuously develop towards more advanced topics, ending with the latest results in this rapidly developing field.
