Research on dendrimers has exploded in the last 15 years, moving from the establishment of synthetic methodologies, particularly in the early years up to the end of nineties, towards sophisticated and wide-ranging applications. Dendrimers play an important role in many different areas, spanning from basic synthetic approaches to artificial photosynthesis, to medicine, to catalysis. The great potential of dendrimers is well-recognized by the hundreds of papers in the field and the increasing number of patents, and stimulated developments in other areas of knowledge, including new characterization techniques. However, some basic principles and methods still continue to give a unity to the field. Although several books on dendrimers have been published during these 15 years, the very recent progresses in new areas now requires a new point of view, trying to give a unifying and comprehensive outlook of the field. Since the first dendrimer was synthesized by Vögtle in 1978, dendrimers have experienced an explosion of scientific interest because of their unique molecular architecture. This resulted in over 5,000 scientific papers and patents published by the end of 2005. The proposed book will cover both fundamental and applicative aspects of dendrimer research. Chapters devoted to basic principles, synthetic methods and strategies, and advanced characterization techniques will be integrated by chapters illustrating the full potential of dendrimers in various fields, like artificial photosynthesis, multi-redox pool systems, diagnostics, biomedical and sensing purposes, design of functional nanostructures. Particular emphasis will be devoted to possible future developments.

Completely revised and substantially extended to reflect the developments in this fast-changing field. It retains the interdisciplinary approach that elegantly combines the chemistry and engineering involved to describe the conception and improvement of chromatographic processes. It also covers recent advances in preparative chromatographic processes for the separation of «smaller» molecules using standard laboratory equipment as well as the detailed conception of industrial chemical plants. The increase in biopharmaceutical substances is reflected by new and revised chapters on different modifications of continuous chromatography as well as ion-exchange chromatography and other separation principles widely used in biochromatography. Following an introductory section on the history of chromatography, the current state of research and the design of chromatographic processes, the book goes on to define the general terminology. There then follow sections on stationary phases, selection of chromatographic systems and process concepts. A completely new chapter deals with engineering and operation of chromatographic equipment. Final chapters on modeling and determination of model parameters as well as model based design, optimization and control of preparative chromatographic processes allow for optimal selection of chromatographic processes. Essential for chemists and chemical engineers in the chemical, pharmaceutical, and food industries.
