Book Description
Irradiation with energetic ion beams often leads to structures with nanometer-sized dimensions. Ion beams can be used to fabricate metallic or semiconducting nanocrystals in optical or electronic host materials or to pattern magnetic or superconducting materials. The properties of nanostructured materials formed by various types of energetic beams can be unique, and as a result, such materials provide an opportunity to investigate physical processes and suggest potential applications. This 2003 book focuses on aspects of nanostructuring with energetic ion beams including nanocrystal synthesis by ion implantation, nanostructure formation induced by radiation effects, ion irradiation through lithographic masks, ion-beam lithography, and focused ion beams. A highlight is a presentation demonstrating the remarkable lithographic abilities of MeV proton beams to 'machine' solid materials on a scale of nanometers. Because of the long range of the proton beam, features with uncommonly high aspect ratios can be obtained. This is the first known instrument of its kind in the world and the first results are extremely promising.

Book Description
This book focuses on recent advances in nanostructured and nanophase materials and their applications. Nanostructured materials consist of domains of less than 100nm and include atom clusters and cluster assemblies, one- and two-dimensionally modulated layers and three-dimensional structures. The term 'nanophase' refers to structures comprised of domains or particles of a single material that are typically less than 100nm, whereas 'nanocomposite' refers to a composite of more than one nanophase. Nanoscale materials can be engineered as homogeneous or porous ceramics, metals, metal oxides, semiconductors, organic polymers, or as composite materials containing these components. This book brings together scientists from many disciplines to share and discuss advances in the field. Topics include: nanophase materials; nanocomposite materials; nanoporous materials; nanostructured materials; applications and properties of nanostructured materials; carbon nanotubes; nanostructured thin films and coatings; and theoretical and modeling studies of nanostructured materials.

Book Description
Twenty years after the discovery of a quasicrystalline compound, the field of quasicrystals still raises interest and is continuously evolving. Quasicrystals display properties different from conventional crystals with small unit cells and present interesting potential for industrial purposes. This book offers an updated look into the field of quasicrystalline research. For example, a report on electrodeposited Al-Cu-Fe quasicrystals shows great promise for industry. It is also demonstrated that when Al-Cu-Fe quasicrystals are used as catalysts, in particular at high temperatures, such quasicrystals outperform conventional industrial catalysts. A new class of quasicrystal, based on a novel type of local order differing from previously observed Mackay- and Bergman-type quasicrystals, is featured. A detailed description of layer-by-layer growth of a Cu film on a quasicrystalline surface is also provided. Additional topics include: synthesis and structure; transport properties; electronic properties; mechanical properties; quasicrystals from metallic glasses; surfaces and coatings; and applications and hydrogen storage.

Book Description
The advent of nanomaterials has introduced a new dimension in applications of energetic and reactive materials. A fundamental understanding of their synthesis mechanisms, atomic- and molecular-scale structural characteristics, and an evaluation of properties combined with modeling of the limits to those properties are required to realize the full potential of energetic and reactive nanomaterials. Many techniques have been recently developed that make it possible to exploit the benefits of the "nano" structure and design materials with desired energy release rates and energy densities, while they also improve their safety, reliability and load-bearing capability. Advances in modeling and characterization have made it possible to determine mechanisms controlling the thermal, chemical and mechanical behavior of nanomaterials. This volume brings together researchers from around the world to assess fundamental studies on synthesis, characterization of structure, and evaluation of properties of energetic/reactive nanomaterials. Applications such as new propellant formulations, underwater detonation developments, biomedical research, and combustion of nanolayered metal films for cladding materials are featured. Topics include: applications and toxicology; synthesis; characterization; characterization and theory; theory and modeling; and general discussion.

Book Description
Nanostructures with critical dimensions less than 100nm endow materials with unique and often superior mechanical, electronic, magnetic and optical properties, which are expected to lead to numerous advanced applications. The current nanotechnology roadmap focuses on exploration and prediction of novel properties of materials at the nanoscale, of efficient synthesis and manufacture of nanoscale materials, and of the integration of nanoscale materials into real-world devices and applications. Self assembly, in which complex building blocks are organized into hierarchical structures via noncovalent interactions, has emerged as one of the most promising techniques for the efficient fabrication of nanostructured materials. This proceedings volume focuses on synthesis of novel nanostructured materials via self assembly, the fundamental understanding of self-assembly processes, the unique properties of nanostructured materials, and their potential applications. The volume is a compendium of current discussions of these topics with special emphasis on the synthesis and fabrication of nanostructured materials via self assembly of organic molecules such as surfactants and block copolymers, inorganic and metallic nanoclusters, nanoparticles, nanorods, nanowires, and other building blocks. It also contains reports on the novel properties and applications of nanostructured materials.

Book Description
Nanofabrication Using Focused Ion and Electron Beams presents fundamentals of the interaction of focused ion and electron beams (FIB/FEB) with surfaces, as well as numerous applications of these techniques for nanofabrication involving different materials and devices. The book begins by describing the historical evolution of FIB and FEB systems, applied first for micro- and more recently for nanofabrication and prototyping, practical solutions available in the market for different applications, and current trends in development of tools and their integration in a fast growing field of nanofabrication and nanocharacterization. Limitations of the FIB/FEB techniques, especially important when nanoscale resolution is considered, as well as possible ways to overcome the experimental difficulties in creating new nanodevices and improving resolution of processing, are outlined. Chapters include tutorials describing fundamental aspects of the interaction of beams (FIB/FEB) with surfaces, nanostructures and adsorbed molecules; electron and ion beam chemistries; basic theory, design and configuration of equipment; simulations of processes; basic solutions for nanoprototyping. Emerging technologies as processing by cluster beams are also discussed. In addition, the book considers numerous applications of these techniques (milling, etching, deposition) for nanolithography, nanofabrication and characterization, involving different nanostructured materials and devices. Its main focus is on practical details of using focused ion and electron beams with gas assistance (deposition and etching) and without gas assistance (milling/cutting) for fabrication of devices from the fields of nanoelectronics, nanophotonics, nanomagnetics, functionalized scanning probe tips, nanosensors and other types of NEMS (nanoelectromechanical systems). Special attention is given to strategies designed to overcome limitations of the techniques (e.g., due to damaging produced by energetic ions interacting with matter), particularly those involving multi-step processes and multi-layer materials. Through its thorough demonstration of fundamental concepts and its presentation of a wide range of technologies developed for specific applications, this volume is ideal for researches from many different disciplines, as well as engineers and professors in nanotechnology and nanoscience.
