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

This book concentrates on both understanding and development of nanocrystalline materials. The original relation that connects grain size and strength, known as the Hall-Petch relation, is studied in the nanometer grain size region. The breakdown of such a relation is a challenge. Why and how to overcome it? Is the dislocation mechanism still operating when the grain size is very small, approaching the amorphous limit? How do we go from the microstructure information to the continuum description of the mechanical properties?

This book helps readers comprehend the principles and fundamentals of defect engineering toward realization of an efficient photocatalyst. The volume consists of two parts, each of which addresses a particulate type of defects. The first, larger section provides a comprehensive and rigorous treatment of the behaviour and nature of intrinsic defects. The author describes how their controlled introduction and consequent manipulation over concentration, distribution, nature and diffusion is one of the most effective and practical methodologies to modify the properties and characteristics of target photocatalytic materials. The second part of the book explains the formation of extrinsic defects in the form of metallic and non-metallic dopants and gives a detailed description of their characteristics as this approach is also often used to fabricate an efficient photocatalyst. Filling the gap in knowledge on the correlation between introduction of defects in various semiconducting materials and their photocatalytic performance, the book is ideal for graduate students, academics and researchers interested in photocatalysts, defect engineering, clean energy, hydrogen production, nanoscale advanced functional materials, CO2 deactivation, and semiconductor engineering.
