Atomic Clusters With Unusual Structure

Atomic Clusters with Unusual Structure, Bonding and Reactivity: Theoretical Approaches, Computational Assessment and Applications reviews the latest computational tools and approaches available for accurately assessing the properties of a cluster, while also highlighting how such clusters can be adapted and utilized for the development of novel materials and applications. Sections provide an introduction to the computational methods used to obtain global minima for clusters and effectively analyze bonds, outline experimental approaches to produce clusters, discuss specific applications, and explore cluster reactivity and usage across a number of fields.Drawing on the knowledge of its expert editors and contributors, this book provides a detailed guide to ascertaining the stability, bonding and properties of atomic clusters. Atomic clusters, which exhibit unusual properties, offer huge potential as building blocks for new materials and novel applications, but understanding their properties, stability and bonding is essential in order to accurately understand, characterize and manipulate them for further use. Searching for the most stable geometry of a given cluster is difficult and becomes even more so for clusters of medium and large sizes, where the number of possible isomers sharply increase, hence this book provides a unique and comprehensive approach to the topic and available techniques and applications. Introduces readers to the vast structural and bonding diversity that clusters show and reflects on their potential for novel application and material development Highlights the latest computational methods and theoretical tools available for identification of the most stable isomers and accurate analysis of bonding in the clusters Focuses on clusters which violate the rules established in traditional chemistry and exhibit unusual structure, bonding and reactivity

Atomic Clusters: From Gas Phase to Deposited brings together a series of chapters, prepared by acknowledged experts in their fields. Both fundamental and practical aspects are addressed of the physics and chemistry of a novel state of matter, namely clusters of small numbers of atoms of nanometre dimensions. This is a field of nanoscience that existed before the word was invented, but has particularly achieved major advances in the recent years. * Contributions from leading experts in solid surfaces research * Cluster science is concerned with the properties of materials on the nano-metre scale * Brings together work on both free (gas-phase) clusters and those deposited on surfaces

This volume on Clusters brings together contributions from a large number of specialists.

This book presents a “snapshot” of the most recent and significant advances in the field of cluster physics. It is a comprehensive review based on contributions by the participants of the 2nd International Symposium on Atomic Cluster Collisions (ISACC 2007) held in July 19–23, 2007 at GSI, Darmstadt, Germany. The purpose of the Symposium is to promote the growth and exhange of scientific information on the structure and properties of nuclear, atomic, molecular, biological and complex cluster systems studied by means of photonic, electronic, heavy particle and atomic collisions. Particular attention is devoted to dynamic phenomena, many-body effects taking place in cluster systems of a different nature — these include problems of fusion and fission, fragmentation, collective electron excitations, phase transitions, etc. Both the experimental and theoretical aspects of cluster physics, uniquely placed between nuclear physics on the one hand and atomic, molecular and solid state physics on the other, are discussed.

The last fifteen years have seen a veritable explosion of clusters research brought about by two relatively new experimental advances - supersonic jet expansions creating cold high density atomic and molecular beams, and laser (mass and optical) spectroscopy. The success and power of these two techniques, taken together and applied to the study of atomic and molecular clusters, are described in this volume. The field of cluster study is a very broad one, propelled by both the potential application of cluster results to many bulk systems and interest in clusters as systems in their own right. The eclectic nature of the collection of chapters in this book reflects well the diverse nature of this area of chemical physics. The book begins with one of the most suprising and controversial of recent cluster studies - those for the carbon system. As with bulk and molecular carbon chemistry, the chemistry of carbon clusters seems to be unique. Nonmetallic main group clusters also form a very interesting set of systems and their structure and chemistry are as fascinating as they are varied. Diatomic/atomic clusters and small polyatomic clusters demonstrate an incredible amount of spectroscopic detail and thus structure, dynamics and, in some instances, chemistry can be characterized for them. Clusters of larger molecules also yield information on structure, dynamics and chemistry but can in addition give information on changes in molecular structure with degree of solvation. As clusters become larger they begin to assume the properties of bulk systems. Finally, some chapters discuss the nucleation and growth of clusters, each from its own unique perspective and point of view. Current efforts involve following these processes from the formation of a two-molecule cluster to liquid drop. Atomic and Molecular Clusters provides the researcher with a survey of the current status of the field and will also be of interest to the student who may discover a new and exciting area of investigation.

The Second International Conference on Atomic and Nuclear Clusters '93 was orga nized in a joint effort by the 'Demokritos' National Center for Scientific Research, G. S. Anagnostatos (representing the atomic physics) and the Hahn-Meitner-Institut, W. von Oertzen (representing the nuclear physics). The subject of clusters - small aggregates of particles - is a topic of primary interest in both atomic and nuclear physics, and also in other fields like in the case of quark-structure of baryons and in cosmology. The interplay between atomic and nuclear physics is a particularly fascinating one because many concepts are common to both fields (quantal effects, shells, geometric structures, collective modes, fission etc. ) This conference was the second after the first one organized by Professor M. Brenner in Abo (Finland) in 1991. The general atmosphere of a joint forum for atomic and nuclear physicists was very fruitful and thus the decision to have a sequence of such meetings has been taken. A third one is planned in St. Petersburg (Russia) with Professor K. Gridnev (St. Petersburg) and Mme. Professor C. Bnkhignac (Orsay) as Chairpersons. The conference site, Fin\. on Santorini island (Greece), was a wonderful choice for a conference. It is small, which helps to keep people concentrated in a smaller community, it has a perfect convention center, the P. Nomikos Conference Center, and a very beautiful landscape formed by a large volcanic crater.
