Fine Particles Science and Technology

Fine Particles Science and Technology deals with the preparation, characterization and technological applications of monodisperse particles in the micro to nano size range. A broad view of this frontier field is given, covering understanding the mechanisms by which uniform fine particles are formed and the search for new processes; the mechanism of the precipitation technique, requiring knowledge of the relationship between the complex solution chemistry and the products formed; the sequence of events leading to the formation of monodisperse colloids. The following topics are presented: microparticles, nanoparticles, applications in the preparation of materials, synthesis and properties, environmental applications, and many others.
