Available in PDF, EPUB and Kindle. Book excerpt: In recent years, interest in the preparation and characterization of the na-noporous materials has grown due to their distinctive properties and potential applications. Among them, silica aerogel are transparent, highly porous and lightest synthetic solids. Silica aerogels, prepared by sol-gel method followed by supercritical drying, have various extraordinary properties viz. low density ( 20 mg/cm3) and thermal conductivity (0.05 W/mK), low sound velocity ( 100 m/s) and large surface area (> 1500 m2/g). Due to this unique combination of properties, aerogels are considered as a new class solid state porous material having various scientific and technological applications like super insulating transparent fillers in double walled windows, catalytic supports, Cerenkov detectors, filters and containers for capturing of micrometeorites in space. However, economic large-scale industrial production of silica aerogels is hampered by expensive supercritical drying methods. The present book describes the results of detailed studies made on the synthesis and characterization of silica aerogels and related nano-porous materials by various methods and precursors at ambient pressure.

Book excerpt: Sol-Gel Science: The Physics and Chemistry of Sol-Gel Processing presents the physical and chemical principles of the sol-gel process. The book emphasizes the science behind sol-gel processing with a chapter devoted to applications. The first chapter introduces basic terminology, provides a brief historical sketch, and identifies some excellent texts for background reading. Chapters 2 and 3 discuss the mechanisms of hydrolysis and condensation for nonsilicate and silicate systems. Chapter 4 deals with stabilization and gelation of sols. Chapter 5 reviews theories of gelation and examines the predicted and observed changes in the properties of a sol in the vicinity of the gel point. Chapter 6 describes the changes in structure and properties that occur during aging of a gel in its pore liquor (or some other liquid). The discussion of drying is divided into two parts, with the theory concentrated in Chapter 7 and the phenomenology in Chapter 8. The structure of dried gels is explored in Chapter 9. Chapter 10 shows the possibility of using the gel as a substrate for chemical reactions or of modifying the bulk composition of the resulting ceramic by performing a surface reaction (such as nitridation) on the gel. Chapter 11 reviews the theory and practice of sintering, describing the mechanisms that govern densification of amorphous and crystalline materials, and showing the advantages of avoiding crystallization before sintering is complete. The properties of gel-derived and conventional ceramics are discussed in Chapter 12. The preparation of films is such an important aspect of sol-gel technology that the fundamentals of film formation are treated at length in Chapter 13. Films and other applications are briefly reviewed in Chapter 14. Materials scientists and researchers in the field of sol-gel processing will find the book invaluable.

This book was released on 2012-10-03 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on porous monolithic materials that are not in the forms of particles, fibers, or films. In particular, the synthetic strategy of porous monolithic materials via the sol–gel method accompanied by phase separation, which is characterized as the non-templating method for tailoring well-defined macropores, is described from the basics to actual synthesis. Porous materials are attracting more and more attention in various fields such as electronics, energy storage, catalysis, sensing, adsorbents, biomedical science, and separation science. To date, many efforts have been made to synthesize porous materials in various chemical compositions—organics, inorganics including metals, glasses and ceramics, and organic-inorganic hybrids. Also demonstrated in this thesis are the potential applications of synthesized porous monolithic materials to separation media as well as to electrodes for electric double-layer capacitors (EDLCs) and Li-ion batteries (LIBs). This work is ideal for graduate students in materials science and is also useful to engineers or scientists seeking basic knowledge of porous monolithic materials.
