Описание: However, to expand the commercial potential of sol-gel technology, two challenges must be met: (1) the quality of sol-gel derived products must continue to meet or exceed the quality of competing products, (2) the production cost of sol-gel products (specially aerogels) must continued to decline.

Описание: This book presents wet chemical sol-gel and hydrothermal methods for 1D oxide nanostructure preparation. These methods represent an attractive route to multifunctional nanomaterials synthesis, as they are versatile, inexpensive and, thus, appropriate for obtaining a wide range of oxide materials with tailored morphology and properties. Three specific oxides (SiO2, TiO2, ZnO) are discussed in detail in order to illustrate the principle of the sol-gel and hydrothermal preparation of 1D oxide nanostructures. Other oxides synthesized via this method are also briefly presented. Throughout the book, the correlation between the tubular structure and the physico-chemical properties of these materials is highlighted. 1D oxide nanostructures exhibit interesting optical and electrical properties, due to their confined morphology. In addition, a well-defined geometry can be associated with chemically active species. For example, the pure SiO2 nanotubes presented a slight photocatalytic activity, while the Pt-doped SiO2 tubular materials act as microreactors in catalytic reactions. In the case of titania and titanate nanotubes, large specific surface area and pore volume, ion-exchange ability, enhanced light absorption, and fast electron-transport capability have attracted significant research interest. The chemical and physical modifications (microwave assisted hydrothermal methods) discussed here improve the formation kinetics of the nanotubes. The ZnO nanorods/tubes were prepared as random particles or as large areas of small, oriented 1D ZnO nanostructures on a variety of substrates. In the latter case a sol-gel layer is deposited on the substrate prior to the hydrothermal preparation. Using appropriate dopants, coatings of ZnO nanorods with controlled electrical behavior can be obtained.
Описание: This book examines the synthetic strategy of porous monolithic materials via the sol-gel method accompanied by phase separation. It includes many electron micrographs, helping general readers to understand the pore structures of the materials.

Описание: Provides new evidence from a range of leading scholars showing that teachers become more effective when they work in organisations that support them in comprehensive and coordinated ways. The studies featured in the book suggest an alternative approach to enhancing teacher quality: creating conditions and school structures that facilitate the transmission and sharing of knowledge among teachers.
Описание: This substantially revised and expanded new edition of the bestselling textbook, addresses the difficulties that can arise with the mathematics that underpins the study of symmetry, and acknowledges that group theory can be a complex concept for students to grasp.

Описание: Research interest in inorganic membrane materials and processes has significantly increased in recent years due to novel, potentially low-cost energy and fuel production applications. This book documents the recent progress in membrane science, especially in advanced materials and novel reaction and separation concepts. The book classifies membranes based on the mechanism of operation, i.e., size exclusion filtration, solution-diffusion, and mixed ion-electron conduction of the permeate streams.
