Book Description
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.

Book Description
In recent years, carbon nitride, a new type of two-dimensional (2D) material, has attracted great interest, in terms of fundamental scientific investigation and potential practical applications, for a range of energy and environmental technologies. This can be largely attributed to its optoelectronic and physicochemical properties, including moderate band gap, adjustable energy band configuration, tailor-made surface functionalities, low cost, metal-free nature, remarkable thermochemical stability, and environmentally benign manufacturing protocol. Nanostructured Carbon Nitrides for Sustainable Energy and Environmental Applications offers a comprehensive, authoritative, and critical account of the recent progress in the development and application of multifunctional carbon nitride materials and their hybrid heterostructures. There are two major objectives of this book: first, to provide a systematic overview of the key design principles toward the fabrication of high-performance carbon nitride–based nanostructures; and second, to provide insights into a range of clean energy technologies and environmental remediation methods that build on these nanoengineered carbon nitrides. This book serves as an important reference source for materials scientists and engineers who are interested in developing their understanding of how carbon-based nanomaterials are being used for sustainable energy and environmental applications. - Helps users gain deeper insights into various aspects of carbon nitride materials from multidisciplinary perspectives - Covers how to apply nanostructured carbon nitrides to tackle global energy and environmental challenges in a sustainable manner - Explains the design and fabrication of carbon nitride-based materials with optimized structures, controlled morphologies, and tailored properties for practical implementation

Book Description
In the last decade, nanomaterials have become a double-edged sword. On one hand, nanomaterials have proven their limitless potential not only for technological applications, but also for medical ones. On the other hand, the increasing use of these nanomaterials has raised concerns regarding their safety for environmental and human health, due to their potential toxicity. The toxic effects of nanomaterials depend on their type, surface geometry, diameter, length and function. This book intends to provide a comprehensive evidence-based overview of nanomaterial toxicity, from their synthesis and characterization, environmental impact, tests to assess their toxicity in vitro and in vivo, ways to modulate their impact on living organisms, to their beneficial use in biomedical applications.
