Biocompatible Hybrid Oxide Nanoparticles for Human Health: From Synthesis to Applications explores the synthesis, structure, properties and applications of functionalized oxide nanoparticles. The books shows the applications of materials depending on their composition and structure, with a focus on silicon, titanium and iron oxides, each of which was chosen because of their unique features, including silica because it is chemically resistant to most organic solvents, harmless to living organisms, can thicken flowable formulations, and increase the strength of materials, titania for its unique chemical, optical, electrophysical and bactericidal properties, and iron-containing materials because they possess important magnetic properties.

Shows how oxide nanoparticles are being used to solve current problems in the fields of environmental protection, medicine, and in the creation of "smart" materials Includes case studies that explore the major characteristics and applications of silica, titania and iron oxide nanomaterials Discusses the use of biocompatible oxide nanostructures in the development of new sensing technology

The study of the chemistry of metal alkoxides, which began more than 100 years ago, is experiencing a renaissance due to the broad application of these compounds as molecular precursors in the synthesis of advanced technological materials based on simple and complex oxides. The solution of this problem is occupying a wide circle of inorganic chemists, technologists specializing in fine synthesis in nonaqueous media, and those working on the production of films and coatings. The application of metal alkoxides in the first step of sol-gel technology (based on hydrolysis of alkoxides with the subsequent dehydration of the hydrated oxides formed) is addressed in this monograph covering the modern literature devoted to all the steps of this process. This book is devoted to the general questions of the chemistry of metal alkoxides - the synthetic routes to them (both laboratory and technology) physiochemical properties, structure, specific features of single groups of alkoxides, theoretical principles of their use for the preparation of simple and complex oxides by the sol-gel method, and major directions of the application of this method in the preparation of functional materials.Also included are the derivatives of single elements of first through eighth groups of the Periodic Table. The tables contain the major data on the alkoxides, phenoxides, siloxides, derivatives of polyatomic alcohols, and phenols, - their composition, structure, preparation techniques, and major physiochemical characteristics. These tables allow the book to be used as a handbook permitting an acquaintance with the distinct compounds and the literature describing them.

Sol-gel processing is a soft-chemistry method to obtain functional materials at low temperatures. This route can be used to produce very sophisticated nanomaterials and to tailor the materials to very specific applications. Adsorption and detection of pollutants, water purification and soil remediation represent challenging fields of application that can be exploited by sol-gel materials. In this volume several contributions from invited speakers and participants at the NATO advanced research workshop on "Sol-gel approaches to materials for pollution control, water purification and soil remediation", which has been held in Kiev, Ukraine on October 2007, are reported. The book offers a wide and updated overview of the most advanced sol-gel methods for materials processing and at the same time presents several case studies concerning possible solutions for environmental issues. General articles on sol-gel from the invited speakers and focused research articles allow getting inside sol-gel applications on this very important field.
