Download or read book Clusters and Cluster Assembled Materials written by and published by . This book was released on 1991 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our work falls naturally into three categories: (1) local density calculations of cluster structures and the development of classical potentials, (2) simulation of thermodynamic properties of clusters and their fusion, and (3) macroscopic (continuum theory) modeling of the sintering process. These topics will be addressed in turn. Although the nominal focus of the proposal is on sintering processes, many issues important to sintering are generic in nature and thus also important in other areas of cluster science. These issues have been approached from a broad perspective, leading to results which impact the whole field of clusters and cluster-assembled materials.

Download or read book Cluster Dynamics Foundations for Developing Nanoscale Materials written by and published by . This book was released on 2003 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attaining the ability to produce materials through cluster assembly offers great potential advantages, namely the prospect of forming nanoscale materials having selected optical, electronic, or structural properties on the one hand, or useful catalytic, reactive or energy storage characteristics on the other. The work conducted as part of this program involved investigations of the properties of transition metal compounds comprised of nitride, carbides and oxides, with attention to their varying electronic nature with cluster size, and composition. Findings are reported from three interrelated phases of work: (1) forming and studying cluster building blocks, elucidating their properties, investigating methods to accomplish their production in the bulk, and assessing their potential for use as cluster assembled materials; (2) studying the excitation and relaxation dynamics of the clusters following photoexcitation, with attention to providing an understanding of their behavior in terms of observed delayed electron and atomic ion emission; and providing baseline data for assessing theoretical approaches for handling the dynamics of systems having a large number of free electrons; and (3) undertaking studies which provide insight into the potential catalytic behavior of selected clusters, Met-Cars and CAMs, including investigations that serve to identify the fundamentals of catalysis of selected reactions.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As matter decreases in size the importance of a single atom increases exponentially. The properties of clusters, molecules with less than 100 atoms, will change drastically with the addition or removal of a single atom. Clusters have been shown to have properties that mimic other elements and properties that are completely unique. Cluster assemblies could enable the tailoring of precise properties in materials, providing cheap replacements for expensive elements, or novel materials for new applications.Aluminum clusters show great potential use in many applications including energy and catalysis. This work is focused on gaining a better understanding of how geometry and electronic structure affect aluminum cluster reactivity and how useful clusters might be successfully assembled into materials. The effects of doping aluminum cluster ions with boron atoms are reported and show that the addition of a single boron atom usually stabilizes the cluster while adding more boron atoms results in a breaking of symmetry and destabilization. A new analytical technique, matrix isolation cavity ring-down spectroscopy (MICRDS) was developed to help bridge the gap between gas phase cluster studies and condensed phase cluster materials. Molecules are trapped in an inert matrix and studied using cavity ring-down spectroscopy. MICRDS has the potential to also combine clusters into small stable units that would maintain their advantageous gas phase properties.

Download or read book Cluster Assembly of Hierarchical Nanostructures written by and published by . This book was released on 1992 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, atom clusters with diameters in the range of 2--20 nm of a variety of materials, including both metals and ceramics, have been synthesized by evaporation and condensation in high-purity gases and subsequently consolidated in situ under ultrahigh vacuum conditions to create nanophase materials. These new utlrafine-grained materials have properties that are often significantly different and considerably improved relative to those of their coarser-grained counterparts owing to both their small grain-size scale and the large percentage of their atoms in grain boundary environments. Since their properties can be engineered during the synthesis and processing steps, cluster-assembled materials appear to have significant potential for the introduction of a hierarchy of both structure and properties. Some of the recent research on nanophase materials related to properties and scale are reviewed and some of the possibilities for synthesizing hierarchical nanostructures via cluster assembly are considered.

Available in PDF, EPUB and Kindle. Book excerpt: Advanced magnetic nanostructures is an emerging field in magnetism and nanotechnology, but the literature consists of a rich variety of original papers and parts of reviews and books whose scope is comparatively broad. This calls for a book with specific emphasis on state-of-the-art synthetic methods for fabricating, characterizing and theoretically modeling new magnetic nanostructures. This book is intended to provide a comprehensive overview of the present state of the field. Leading researchers world-wide have contributed a survey of their special ties to guide the reader through the exploding literature in nanomagnetic structures. The focus is on deliberately structured nanomagnets. It includes cluster assembled, self-organized and patterned thin films but excludes, for example, multilayered thin films. We target both industrial and academic researchers in magnetism and related areas, such as nanotechnology, materials science, and theoretical solid-state physics.

Download or read book Physics and Chemistry of Finite Systems From Clusters to Crystals written by Peru Jena and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent innovations in experimental techniques such as molecular and cluster beam epitaxy, supersonic jet expansion, matrix isolation and chemical synthesis are increasingly enabling researchers to produce materials by design and with atomic dimension. These materials constrained by sire, shape, and symmetry range from clusters containing as few as two atoms to nanoscale materials consisting of thousands of atoms. They possess unique structuraI, electronic, magnetic and optical properties that depend strongly on their size and geometry. The availability of these materials raises many fundamental questions as weIl as technological possibilities. From the academic viewpoint, the most pertinent question concerns the evolution of the atomic and electronic structure of the system as it grows from micro clusters to crystals. At what stage, for example, does the cluster look as if it is a fragment of the corresponding crystal. How do electrons forming bonds in micro-clusters transform to bands in solids? How do the size dependent properties change from discrete quantum conditions, as in clusters, to boundary constrained bulk conditions, as in nanoscale materials, to bulk conditions insensitive to boundaries? How do the criteria of classification have to be changed as one goes from one size domain to another? Potential for high technological applications also seem to be endless. Clusters of otherwise non-magnetic materials exhibit magnetic behavior when constrained by size, shape, and dimension. NanoscaIe metal particles exhibit non-linear opticaI properties and increased mechanical strength. SimiIarly, materials made from nanoscale ceramic particIes possess plastic behavior.

Download or read book Metallic Glasses written by Behrooz Movahedi and published by BoD – Books on Demand. This book was released on 2016-08-17 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallic glasses and amorphous materials have attracted much more attention in the last two decades. A noncrystalline solid produced by continuous cooling from the liquid state is known as a glass. From the other point of view, a noncrystalline material, obtained by any other process, for example, vapor deposition or solid-state processing methods such as mechanical alloying, but not directly from the liquid state, is referred to as an amorphous material. At this moment, bulk metallic glasses (BMG) are appearing as a new class of metallic materials with unique physical and mechanical properties for structural and functional usage. Extreme values of strength, fracture toughness, magnetic properties, corrosion resistance, and other properties have been registered in BMG materials.
