The electrochemical deposition of doped silica, ORMOSIL and related nanocomposite thin films at the surface of electrodes is opening a whole new field of applications. In the latter case, a potential is applied to an alkoxide solution which alters the pH on the electrode surface and thus enhances the rate of condensation.40 The resulting single-step...

Another new class of materials developed in recent years is the organically modified silicates (ormosils) [50-53]. As their name implies, ormosils are silicate materials that have been modified at the molecular level with an organic component. These materials are often refered to as molecular composites or nanocomposites [53]. They combine the hardness and strength of an inorganic glass with the fracture toughness of a polymer material [50]. Unlike the composites of the previous section, however, ormosils are prepared from one solution. In this regard, ormosils are more like copolymers than composites, except... 

In this chapter we review the principles of monolith fabrication, routes for febrication of monoUths such as xerogel monoliths, nanocomposite monoliths, ORMOSIL monohths, hybrid monoliths, and aerogel monohths. In addition, we will present several characterization methods of monohths, encapsulation or doping in monohths, and examples of apphcations of monohths.
