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 Structure and Properties of Atomic Nanoclusters written by Julio A. Alonso and published by World Scientific. This book was released on 2012 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic clusters are aggregates of atoms containing a few to several thousand atoms. Due to the small size of these pieces of matter, the properties of atomic clusters in general are different from those of the corresponding material in the macroscopic bulk phase. This monograph presents the main developments of atomic clusters and the current status of the field. The book treats different types of clusters with very different properties: clusters in which the atoms or molecules are tied by weak van der Waals interactions, metallic clusters, clusters of ionic materials, and network clusters made of typical covalent elements. It includes methods of experimental cluster synthesis as well as the structural, electronic, thermodynamic and magnetic properties of clusters, covering both experiments and the theoretical work that has led to our present understanding of the different properties of clusters. The question of assembling nanoclusters to form solids with new properties is also considered. Having an adequate knowledge of the properties of clusters can be of great help to any scientist working with objects of nanometric size. On the other hand, nanoclusters are themselves potentially important in fields like catalysis and nanomedicine.

Download or read book An Introduction to Cluster Science written by Phuong Mai Dinh and published by John Wiley & Sons. This book was released on 2013-09-30 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the need for a solid textbook, this short primer in cluster science is ideal for a one-semester lecture for advanced undergraduate students. It is based on a series of lectures given by the well-established and recognized authors for the past ten years. The book covers both the basics of the domain as well as up-to-date developments. It can be divided roughly into two parts. The first three chapters introduce basic concepts of cluster science. Chapter 1 provides a general introduction, complemented by chapter 2 on experimental and chapter 3 on theoretical aspects. The second half of the book is devoted to a systematic presentation of free cluster properties, and to a thorough discussion of the impact of clusters in other domains of science. These explicitly worked-out links between cluster physics and other research areas are unique both in terms of fundamental aspects and of applications, and cannot be found elsewhere in the literature. Also suitable for researchers outside of the field looking for an introduction to cluster science.

Download or read book Tailoring and Scaling Energetic Aluminum Clusters Into Cluster Assembled Materials written by Jordan Smith and published by . 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 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.

Download or read book Advances in Metal and Semiconductor Clusters written by M.A. Duncan and published by Elsevier. This book was released on 1998-07-27 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cluster Materials is the fourth volume of the highly successful series Advances in Metal and Semiconductor Clusters. In this volume the focus is on the properties of clusters which determine their potential applications as new materials. Metal and semiconductor clusters have been proposed as precursors for materials or as actual materials since the earliest days of cluster research. In the last few years, a variety of techniques have made it possible to produce clusters in sizes varying from a few atoms up to several thousand atoms. While some measurements are performed in the gas phase on non-isolated clusters, many cluster materials can now be isolated in macroscopic quantities and more convenient studies of their properties become possible. In this volume the authors focus on measurement of optical, electronic, magnetic, chemical and mechanical properties of clusters or of cluster assemblies. All of these properties must fall into acceptable ranges of behaviour before useful materials composed of clusters can be put into practical applications. As evidenced by the various work described here, the realisation of practical products based on cluster materials seems to be approaching rapidly.

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.
