Nanomaterials exhibit unique mechanical and physical properties compared to their coarse-grained counterparts, and are consequently a major focus of current scientific research. Defect structure in nanomaterials provides a detailed overview of the processing methods, defect structure and defect-related mechanical and physical properties of a wide range of nanomaterials. The book begins with a review of the production methods of nanomaterials, including severe plastic deformation, powder metallurgy and electrodeposition. The lattice defect structures formed during the synthesis of nanomaterials are characterised in detail. Special attention is paid to the lattice defects in low stacking fault energy nanomaterials and metal – carbon nanotube composites. Topics covered in the second part of the book include a discussion of the thermal stability of defect structure in nanomaterials and a study of the influence of lattice defects on mechanical and hydrogen storage properties. - Gives in-depth, physically based explanations for the relationships between the defect structure and mechanical properties of nanomaterials - Covers a wide range of nanomaterials including metals; alloys; ceramics; diamond; carbon nanotubes and their composites - Provides a detailed characterization of the lattice defect structure in nanomaterials

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?

Heterogeneous catalysis, exploiting photo- and electrochemical reactions, has expanded rapidly in recent decades, having undergone various developments, especially from both energetic and environmental points of view. Photocatalysis plays a pivotal role in such applications as water splitting and air/water remediation. Electrocatalysis can be found in a large array of research fields, including the development of electroanalytical sensors, wastewater treatment, and energy conversion devices (e.g., batteries, fuel and solar cells, etc.). Therefore, the fine control of the synthetic procedures, together with extensive physicochemical characterisations of the tailor-made catalytic nanomaterials, are of fundamental importance to achieving the desired results. The present book will include recent enhancements in oxide/metal nanoparticles for photocatalytic and electrocatalytic applications, especially in the fields of pollutants abatement and energy conversion.

Defects in Advanced Electronic Materials and Novel Low Dimensional Structures provides a comprehensive review on the recent progress in solving defect issues and deliberate defect engineering in novel material systems. It begins with an overview of point defects in ZnO and group-III nitrides, including irradiation-induced defects, and then look at defects in one and two-dimensional materials, including carbon nanotubes and graphene. Next, it examines the ways that defects can expand the potential applications of semiconductors, such as energy upconversion and quantum processing. The book concludes with a look at the latest advances in theory. While defect physics is extensively reviewed for conventional bulk semiconductors, the same is far from being true for novel material systems, such as low-dimensional 1D and 0D nanostructures and 2D monolayers. This book fills that necessary gap. - Presents an in-depth overview of both conventional bulk semiconductors and low-dimensional, novel material systems, such as 1D structures and 2D monolayers - Addresses a range of defects in a variety of systems, providing a comparative approach - Includes sections on advances in theory that provide insights on where this body of research might lead
