Metal Oxide Nanoparticles in Organic Solvents discusses recent advances in the chemistry involved for the controlled synthesis and assembly of metal oxide nanoparticles, the characterizations required by such nanoobjects, and their size and shape depending properties. In the last few years, a valuable alternative to the well-known aqueous sol-gel processes was developed in the form of nonaqueous solution routes. Metal Oxide Nanoparticles in Organic Solvents reviews and compares surfactant- and solvent-controlled routes, as well as providing an overview of techniques for the characterization of metal oxide nanoparticles, crystallization pathways, the physical properties of metal oxide nanoparticles, their applications in diverse fields of technology, and their assembly into larger nano- and mesostructures. Researchers and postgraduates in the fields of nanomaterials and sol-gel chemistry will appreciate this book’s informative approach to chemical formation mechanisms in relation to metal oxides.

Non-sag (NS) tungsten is a dispersion-strengthened microalloy with elemental potassium, which is contained as microscopic bubbles in the tungsten lattice. Under working conditions in an incandescent lamp the potassium is a gas under high pressure. These gas bubbles essentially prevent the recrystallization of the tungsten wire and are responsible for the outstanding creep resistance of NS tungsten at the extremely high temperatures of a glowing lamp filament. More than 90% of NS tungsten is used for incandescent lamps. In addition, small amounts are used as defroster heating wires in automobile windshields and as heating wire coils for aluminium evaporation in metallization applications. The presented papers deal with the chemical reactions and the chemical compounds occurring along the path from tungsten raw materials to the final NS tungsten filament; a compendium of present knowledge on the different chemical aspects of NS tungsten manufacture is presented. It is composed of nine individual papers, each of them written by experts working in the field.

The field of organic/inorganic hybrids has evolved significantly, providing materials with increasing architectural complexities and functionalities. Scientists involved in this field are gradually moving from building materials using a classical molecular approach (e.g. polymerization) to assembling materials on the nanoscale, using a variety of innovative strategies which can vary from the assembly of DNA motifs, to the formation of mesoporous materials by spinodal decomposition, or the use of nanoparticles or oxoclusters as nanobuilding blocks for building complex structures such as nacre-like transition metal oxides. This precise control over the materials architecture also adds functionality to the hybrid materials, whether it is for designing special membranes for phase separation and chromatography or thin films for photonic or magnetic applications. This book presents contributions from researchers worldwide and discusses organosiloxane-based materials; mesoporous materials and films; layered materials; surface and interface modification and characterization; controlled release and biological applications; nanoparticles synthesis and assembly; nanocomposites and new concepts.

As the environmental impact of existing construction and building materials comes under increasing scrutiny, the search for more eco-efficient solutions has intensified. Nanotechnology offers great potential in this area and is already being widely used to great success. Nanotechnology in eco-efficient construction is an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction. Following an introduction to the use of nanotechnology in eco-efficient construction materials, part one considers such infrastructural applications as nanoengineered cement-based materials, nanoparticles for high-performance and self-sensing concrete, and the use of nanotechnology to improve the bulk and surface properties of steel for structural applications. Nanoclay-modified asphalt mixtures and safety issues relating to nanomaterials for construction applications are also reviewed before part two goes on to discuss applications for building energy efficiency. Topics explored include thin films and nanostructured coatings, switchable glazing technology and third generation photovoltaic (PV) cells, high-performance thermal insulation materials, and silica nanogel for energy-efficient windows. Finally, photocatalytic applications are the focus of part three, which investigates nanoparticles for pollution control, self-cleaning and photosterilisation, and the role of nanotechnology in manufacturing paints and purifying water for eco-efficient buildings. Nanotechnology in eco-efficient construction is a technical guide for all those involved in the design, production and application of eco-efficient construction materials, including civil engineers, materials scientists, researchers and architects within any field of nanotechnology, eco-efficient materials or the construction industry. Provides an authoritative guide to the role of nanotechnology in the development of eco-efficient construction materials and sustainable construction Examines the use of nanotechnology in eco-efficient construction materials Considers a range of important infrastructural applications, before discussing applications for building energy efficiency

The precipitation of metal oxides from aqueous solutions creates nanoparticles with interesting solid state properties, thus building a bridge between solution chemistry and solid state chemistry. This book is the first monograph to deal with the formation of metal oxides from aqueous solutions with emphasis on the formation and physical chemistry of nanoparticles. Metal Oxide Chemistry and Synthesis: From Solution to Solid State * Provides a comprehensive introduction to the synthesis of finely divided materials * Presents the chemistry, physics and applications of these materials * Builds a bridge between classical solution chemistry and new developments in solid state chemistry * Introduces an important new area in inorganic chemistry Part I examines the mechanism of condensation of aqueous cations leading to polynuclear species or lattices, and rationalizes the behaviour of cations in precipitation phenomena by identifying pathways from soluble species to solids. The cation complex is also analysed in relation to the synthesis of some technologically interesting polymetallic oxides, e.g. ferroelectric, ferrimagnetic and supraconductor materials. Part II is devoted to the surface chemistry of oxide particles. The basic concepts relating to the reactivity of the oxide-solution interface are introduced and applied to various adsorption phenomena, such as aggregation, stability of particle size against ripening, etc. These properties are exploited for the synthesis of nanomaterials for a broad range of applictions such as ceramic powders, catalysts and nanocomposites. This will also be of interest to those wishing to understand geochemical and some biological processes. As well as being invaluable to researchers and postgraduate students of inorganic chemistry, this book will also be appreciated by solid-state chemists, materials scientists and colloid chemists with an interest in metal oxides.

Following an introduction to biogenic metal nanoparticles, this book presents how they can be biosynthesized using bacteria, fungi and yeast, as well as their potential applications in biomedicine. It is shown that the synthesis of nanoparticles using microbes is eco-friendly and results in reproducible metal nanoparticles of well-defined sizes, shapes and structures. This biotechnological approach based on the process of biomineralization exploits the effectiveness and flexibility of biological systems. Chapters include practical protocols for microbial synthesis of nanoparticles and microbial screening methods for isolating a specific nanoparticle producer as well as reviews on process optimization, industrial scale production, biomolecule-nanoparticle interactions, magnetosomes, silver nanoparticles and their numerous applications in medicine, and the application of gold nanoparticles in developing sensitive biosensors.
