Nanostructures : synthesis, functional properties and applications ; [Advanced Study Institute on Synthesis, Functional Properties & Applications of Nanostructures, held at the Knossos Royal Village, Heraklion, Crete, Greece, July 26, 2002 - August 4, 200

The Advanced Study Institute on Synthesis, Functional Properties and Applications of Nanostructures, held at the Knossos Royal Village, Heraklion, Crete, Greece, July 26, 2002 - August 4, 2002, successfully reviewed the state-of-the-art of nanostructures and nanotechnology. It was concluded that Nanotechnology is widely agreed to be the research focus that will lead to the next generation of breakthroughs in science and engineering. There are three cornerstones to the expectation that Nanotechnology will yield revolutionary advances in understanding and application: • Breakthroughs in properties that arise from materials fabricated from the nanoscale. • Synergistic behavior that arise from the combination of disparate types of materials (soft vs. hard, organic vs. inorganic, chemical vs. biological vs. solid state) at the nanoscale. • Exploitation of natural (e.g. chemical and biological) assembly mechanisms that can accomplish structural control at the nanoscale. It is expected that this will lead to paradigms for assembling bio-inspired functional systems that accomplish desirable properties that are either unavailable or prohibitively expensive using top-down approaches.

Papers from a summer 2001 meeting review the latest work in nanostructures and nanotechnology, with an emphasis on biomedical and information technology applications. Discussion encompasses embedded and natural sensing, information processing, and actuation of responses to the physical environment. Material is presented in chapters on synthesis of nanostructures, nanobiotechnology, processing and consolidation, modeling and mechanical behavior, mechanical properties of nanomaterials, nanocrystallization and phase transformations in nanostructured materials, nanostructured films and coatings, characterization of functionalized nanostructures, quantum dots, and nanowires. Annotation : 2004 Book News The book emphasizes the development of useful implementations and applications of nanotechnology. One key issue addressed is how to access, from the macroscopic world, the extremely high information density of nanostructured systems. One way to do this is by using bio-inspiration - techniques where we apply lessons learned from living systems to design new materials with localized feedback mechanisms. Specifically, the book evaluates the most advanced and innovative syntheses of nanostructures, the most novel properties and functionalities and the most potential applications as components of advanced technological systems and as materials tailored for a great variety of special needs.
