The next three chapters (Chapters 9-11) focus on the deposition of nano-structured or microstructured films and entities. Porous oxide thin films are, for example, of great interest due to potential application of these films as low-K dielectrics and in sensors, selective membranes, and photovoltaic applications. One of the key challenges in this area is the problem of controlling, ordering, and combining pore structure over different length scales. Chapter 9 provides an introduction and discussion of evaporation-induced self-assembly (EISA), a method that combines sol-gel synthesis with self-assembly and phase separation to produce films with a tailored pore structure. Chapter 10 describes how nanomaterials can be used as soluble precursors for the preparation of extended... 

In the past several years, an important advancement has been achieved in the synthesis of ID nanomaterials via hydrothermal treatments [19,42,44,108]. The typical procedure is that precursors and proper agents capable of regulating or templating the crystal growth are added to distilled water with appropriate ratios, and then the mixture is placed in an autoclave for the crystallization at an elevated temperature, time, and pressure. The major advantage of this technique is that lots of materials can be made soluble in water by heating and pressurizing the system elose to the critical points [42]. As a result, a number of raw materials are usable...
