Nanoparticle Formation, modes of particle growth, from surface mononuclear formation controlled to diffusion controlled, are summarized. Examples of real particles obtained are described. The case of monodisperse nanoparticles and particles made by the St?ber process are the focus of a special section. More recent subfiel

Wet Gels and Their Drying,r classification according to their structure and their behavior in the wet state. In particular, their shrinking, swelling, syneresis, and aging behavior are described. The drying techniques of wet gels are finally reviewed. They comprise evaporation of their liquid matrix to produce xerogels, and

Applications of Sol-Gel Processing,ct of this chapter. A first domain concerns direct applications in the sol or in the gel state. The various types of gel shaping come next. The techniques reviewed here comprise coatings and thin films, fibers, and monoliths directly obtained from gel monoliths, or from gel-derived powder packing. M
