Structure And Properties Of Nanoalloys

Structure and Properties of Nanoalloys is devoted to the topic of alloy nanoparticles, the bi-or multicomponent metallic nanoparticles that are often called nanoalloys. The interest in nanoalloys stems from the wide spectrum of their possible applications in the fields of catalysis, magnetism, and optics. Nanoalloys are also interesting from a basic science point-of-view due to the complexity of their structures and properties. Nanoalloys are presently a very lively research area, with impressive developments in the last ten years. This book meets the need to systematize the wealth of experimental and computational results generated over the last decade. Provides a well-organized, coherent overall structure, with a tutorial style format ideal for teaching and self-study In-depth and fluent descriptions by a single leading academic Presents a wealth of experimental and computational results generated over the last decade

Bimetallic nanoparticles, also called nanoalloys, are at the heart of nanoscience because of their ability to tune together composition and size for specific purposes. By approaching both their physical and chemical properties, Nanoalloys: Synthesis, Structure & Properties provides a comprehensive reference to this research field in nanoscience by addressing the subject from both experimental and theoretical points of view, providing chapters across three main topics: Growth and structural properties Thermodynamics and electronic structure of nanoalloys Magnetic, optic and catalytic properties The growth and elaboration processes which are the necessary and crucial part of any experimental approach are detailed in the first chapter. Three chapters are focused on the widely used characterization techniques sensitive to both the structural arrangements and chemistry of nanoalloys. The electronic structure of nanoalloys is described as a guide of useful concepts and theoretical tools. Chapters covering thermodynamics begin with bulk alloys, going to nanoalloys via surfaces in order to describe chemical order/disorder, segregation and phase transitions in reduced dimension. Finally, the optical, magnetic and catalytic properties are discussed by focusing on nanoparticles formed with one element to track the modifications which occur when forming nanoalloys. The range and detail of Nanoalloys: Synthesis, Structure & Properties makes it an ideal resource for postgraduates and researchers working in the field of nanoscience looking to expand and support their knowledge of nanoalloys.

Nanoalloys: From Fundamentals to Emergent Applications presents and discusses the major topics related to nanoalloys at a time when the literature on the subject remains scarce. Particular attention is paid to experimental and theoretical aspects under the form of broad reviews covering the most recent developments. The book is organized into 11 chapters covering the most fundamental aspects of nanoalloys related to their synthesis and characterization, as well as their theoretical study. Aspects related to their thermodynamics and kinetics are covered as well. The coverage then moves to more specific topics, including optics, magnetism and catalysis, and finally to biomedical applications and the technologically relevant issue of self-assembly. With no current single reference source on the subject, the work is invaluable for researchers as the nanoscience field moves swiftly to full monetization. Encapsulates physical science of structure, properties, size, composition and ordering at nanoscale, aiding synthesis of experimentation and modelling Multi-expert and interdisciplinary perspectives on growth, synthesis and characterization of bimetallic clusters and particulates supports expansion of your current research activity into applications Synthesizes concepts and draws links between fundamental metallurgy and cutting edge nanoscience, aiding interdisciplinary research activity

Nanoalloys, Second Edition, provides a self-contained reference on the physics and chemistry of nanoscale alloys, dealing with all important aspects that range from the theoretical concepts and the practical synthesis methods to the characterization tools. The book also covers modern applications of nanoalloys in materials science, catalysis or nanomedicine and discusses their possible toxicity. Covers fundamentals and applicative aspects of nanoalloys in a balanced presentation, including theoretical and experimental perspectives Describes physical and chemical approaches, synthesis and characterization tools Illustrates the potential benefit of alloying on various applications ranging from materials science to energy production and nanomedicine Updates and adds topics not fully developed at the time of the 1st edition, such as toxicity and energy applications

This comprehensive reference work satisfies the need for in-depth and multidisciplinary coverage of the current state of the art of magnetic hybrid nanoalloys (MHNAs) and their polymer and ceramic nanocomposites. MHNAs represent one of the most challenging research areas in modern science and technology. These materials are stiff and strong with remarkable electronic, mechanical, electrical, thermal and biocompatible properties, and a high potential for multifunctional applications ranging from industry to medicine. The peer-reviewed literature is already extensive, witnessing rapid progress in experimental and theoretical studies on fundamental properties as well as various advanced applications. Part 1 covers theory, modelling, and synthesis (growth and alloying mechanisms) of MHNAs. Formation mechanisms of magneto-electric multiferroic materials, magnetic carbon nanotube (CNTs), and perovskite materials, which are a novel class of next-generation multifunctional nanomaterials, are discussed. The second part focuses on characterization techniques for electrical and dielectrical, rheological, biocompatibility, and other properties, as well as applications in the industrial, agricultural, environmental, and biomedical sectors. Finally, life cycle assessment is considered as essential to the development of nanomaterials and nanoproducts from MHNAs. Advanced undergraduate and graduate students, researchers, and other professionals in the fields of materials science and engineering, polymer science, surface science, bioengineering, and chemical engineering will find comprehensive and authoritative information for solving fundamental and applied problems in the characterization and use of these multifunctional nanomaterials.

"This volume focuses on nanoalloys, which have lately been of increasing interest for a number of reasons. One of the major reasons is the fact that their chemical and physical properties can be tuned by varying the composition and atomic ordering, as well as the size of the clusters. Nanoalloy surface structures, compositions and degree of segregation or mixing are important in determining their properties." "Nanoalloys often display structures and properties which are distinct from those of the pure elemental clusters and they may also display properties which are distinct from the corresponding bulk alloys, due to finite size effects. In addition to experimental studies (synthesis, characterisation and property measurement), nanoalloys are attracting increasing attention from the point of view of theory and simulation." "Nanoalloys are also proving to be of interest in a number of scientific and technological applications, including: catalysis; fuel cells; magnetics; optics; and electronics. Work is presented on all aspects of nanoalloys: synthesis, characterisation, theory and simulation, property measurements and technological applications."--BOOK JACKET.
