Defect Structure and Properties of Nanomaterials: Second and Extended Edition covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites. This new edition is fully revised and updated, covering important advances that have taken place in recent years. Nanostructured materials exhibit unique mechanical and physical properties compared with their coarse-grained counterparts, therefore these materials are currently a major focus in materials science. The production methods of nanomaterials affect the lattice defect structure (vacancies, dislocations, disclinations, stacking faults, twins, and grain boundaries) that has a major influence on their mechanical and physical properties. In this book, the production routes of nanomaterials are described in detail, and the relationships between the processing conditions and the resultant defect structure, as well as the defect-related properties (e.g. mechanical behavior, electrical resistance, diffusion, corrosion resistance, thermal stability, hydrogen storage capability, etc.) are reviewed. In particular, new processing methods of nanomaterials are described in the chapter dealing with the manufacturing procedures of nanostructured materials. New chapters on (i) the experimental methods for the study of lattice defects, (ii) the defect structure in nanodisperse particles, and (iii) the influence of lattice defects on electrical, corrosion, and diffusion properties are included, to further enhance what has become a leading reference for engineering, physics, and materials science audiences. Provides a detailed overview of processing methods, defect structure, and defect-related mechanical and physical properties of nanomaterials Covers a wide range of nanomaterials including metals, alloys, ceramics, diamond, carbon nanotubes, and their composites Includes new chapters covering recent advances in both processing techniques and methods for the study of lattice defects Provides valuable information that will help materials scientists and engineers highlight lattice defects and the related mechanical and physical properties

Magnetic nanoparticles appear naturally in rock magnetism together with a large distribution of sizes and shapes. They have numerous applications from nano-size magnetic memories to metamaterials for electromagnetic waves as well as biological applications such as nanosurgery with minimal traumatism. Their long-ranged size- and shape-dependent dipolar interactions provide numerous useful properties. This book describes the preparation as well as the magnetic properties of nanoparticles and also considers 2D dots, nearly spherical samples, elongated samples, and various assemblies of nanoparticles. The authors report the static magnetic structures and dynamic properties of these nanoparticles and the topological defects in 2D and 3D nanoparticles with new examples of S-shaped vortex or antivortex and of bent vortex or antivortex in 3D nanoparticles. The spectrum of magnetic excitations is shown to exhibit the occurrence of gaps, a key for magnonic metamaterial devices. Magnetic excited states are also considered with their coupling to nanoparticle elastic properties.
