Taschenbuch. Condizione: Neu. Neuware - Atomic collisions offer some unique opportunities to study atomic structure and reaction mechanisms in experiment and theory, especially for projectiles of high atomic number provided by modern accelerators. The book is meant as an introduction into the field and provides some basic theoretical understanding of the atomic processes occurring when a projectile hits another atom. It also furnishes the tools for a mathematical description, however, without going deeper into the technical details, which can be found in the literature given. With this aim, the focus is on reactions, in which only a single active electron participates. Collisional excitation, ionization and charge transfer are discussed for collision velocities ranging from slow to comparable to thespeed of light. For the highest projectile velocities, energy can be converted into mass, so that electron-positron pairs are created. In addition to the systematic treatment, a theoretical section specializes on electron-electroncorrelations and three chapters are devoted to selected highlights bordering to surface science and to physics with antiprotons. \* Simple access to the theory of collisions between ions and atoms\* Systematic treatment of basic features needed for an understanding\* Mathematical details are omitted and referred to references\* In order to bear out the essential ideas most clearly, a single active electron is assumed in most cases\* In selected examples, theoretical results are confronted with experiment\* Discussion supported by a large number of illustrations\* Selected highlights in borderline fields are presented.

Buch. Condizione: Neu. Neuware - Bonding Theory for Metals and Alloys exhorts the potential existence of covalent bonding in metals and alloys. Through the recognition of the covalent bond in coexistence with the 'free' electron band, the book describes and demonstrates how the many experimental observations on metals and alloys can all be reconciled. Subsequently, it shows how the individual view of metals and alloys by physicists, chemists and metallurgists can be unified. The physical phenomena of metals and alloys covered in this book are: Miscibility Gap between two liquid metals; Phase Equilibrium Diagrams; Phenomenon of Melting. Superconductivity; Nitinol; A Metal-Alloy with Memory; Mechanical Properties; Liquid Metal Embrittlement; Superplasticity; Corrosion; The author introduces a new theory based on 'Covalon' conduction, which forms the basis for a new approach to the theory of superconductivity. This new approach not only explains the many observations made on the phenomenon of superconductivity but also makes predictions that have been confirmed. \* Openly recognizes the electrons as the most important and the only factor in understanding metals and alloys\* Proposes Covalon conduction theory, which carries current in covalent bonded pairs\* Investigates phase diagrams both from theoretical and experimental point of view.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A classic in the area of organic synthesis, Strategies and Tactics in Organic Synthesis provides a forum for investigators to discuss their approach to the science and art of organic synthesis. Rather than a simple presentation of data or a second-hand analysis, we are given stories that vividly demonstrate the power of the human endeavour known as organic synthesis and the creativity and tenacity of its practitioners. First hand accounts of each project tell of the excitement of conception, the frustration of failure and the joy experienced when either rational thought and/or good fortune give rise to successful completion of a project. In this book we learn how synthesis is really done and are educated, challenged and inspired by these stories, which portray the idea that triumphs do not come without challenges. We also learn that we can meet challenges to further advance the science and art of organic synthesis, driving it forward to meet the demands of society, in discovering new reactions, creating new designs and building molecules with atom and step economies that provide solutions through function to create a better world. 500 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Zeolites are the most frequently used industrial catalysts. Their applications range from oil refining, petrochemistry and the synthesis of special chemicals to environmental catalysis. Rapid progress in basic research and the development of new processes has resulted in the first Federation of European Zeolite Associations (FEZA) School on Zeolites. Zeolites and Ordered Mesoporous Materials: Progress and Prospects reflects the programme of the first School on Zeolites, held in Prague on August 20-21, 2005. Readers gain insight into the synthesis of the ever-expanding spectrum of zeolites, zeotypes and ordered mesoporous materials including the use of zeolites and mesoporous materials as catalysts in organic conversions. These range from the fascinating ship-in-bottle systems via cascade reactions to bulk applications in oil-refining and petrochemistry. Contributions from world experts enhance the book, with select chapters on trends in the molecular sieves field, zeolite structures, ion-exchange properties of zeolites, advanced applications (with unique technologies and opportunities) and a chapter on natural zeolites. 394 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Switch-Mode Power Converters introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters.
