Introduction to Optical Components
by Roshan L. Aggarwal Kambiz AlaviThis book provides readers with a brief introduction to optical components. Materials presented in this book prepare readers to deal with optical components in the areas of optics and optical technology. Introduction to Optical Components features nine chapters with topics ranging from lenses (materials, magnifiers, and cameras); mirrors (spherical, ellipsoidal, and aberrations); diffraction gratings (holographic and multilayer dielectric); polarizers (birefringent, reflective, and Jones matrix algebra); windows (UV and AR coating materials); filters (neutral density and Raman); beamsplitters (plate, cube, and pellicle); sources (light-emitting diodes and lasers); and detectors (thermal, photon, and photodetector noise). <P><P>This text also features a detailed discussion of non-ideal effects for practical components using minimal amounts of derivations (that do not compromise essential physical, mathematical, or material properties). While there are numerous books that feature "optical" in their title, to date, no textbook on optical components exists. It is for this reason that Introduction to Optical Components is such a vital resource. The technical level of this book is equivalent to an undergraduate course in the optics and optical technology curriculum. Students are required to have little familiarity with optics. Practitioners in optics and optical technology will also find this book useful. Each chapter includes numerous mathematical equations; tables providing useful optical parameters for many optical materials; and end-of-chapter questions and their corresponding solutions.

Introduction to Particle Technology
by Martin J. Rhodes Jonathan SevilleINTRODUCTION TO PARTICLE TECHNOLOGY A new edition of the indispensable guide to particulates and powders Particle technology concerns the formation, processing and properties of the particles and powders which make up many of the products that surround us. Such products range from the cement and aggregate in the built environment to pharmaceuticals and processed foods. Most of the process industries involve particles, either as essential components such as catalysts or as intermediate or final products, and minerals such as the rare earths that are generally mined and processed in particulate form. Particles can have many beneficial uses but they can also cause harm in the environment and, through inhalation, to the individual. In all cases, the powder properties, particularly particle size, are crucially important. This well-known textbook, now in its 3rd edition, provides an easily-understood introduction to the underlying scientific principles of particle technology, together with examples of how these principles can be used in practical design and operation of industrial processes. Each chapter contains both worked examples and exercises for the student. Based on feedback from students and users of the earlier editions, this revised and expanded text includes introductory chapters on particles as products and on computational methods. The topics have been selected to give coverage of the broad areas of particle technology and include: Characterization (size analysis, surface area) Processing (granulation, fluidization) Particle formation (granulation, crystallisation, tableting, size reduction) Storage and transport (hopper design, pneumatic conveying, standpipes) Separation (filtration, settling, cyclones) Safety (fire and explosion hazards, health hazards) Engineering the properties of particulate systems to achieve desired product performance Discrete element modelling of particulate systems Introduction to Particle Technology, 3rd Edition is essential reading for students of chemical engineering.

Introduction to Peak Oil
by R. W. BentleyThis book examines the physical andeconomic characteristics of the global oil resource to explain why peak oil hasbeen so poorly understood. The author draws on information held in oil industrydatasets that are not widely available outside of the specialist literature,and describes a number of methods that have been successfully used to predictoil peaks. In contrast to the widely-held view that 'all oil forecasts arewrong', these methods correctly predicted the current peak in globalconventional oil production. Current oil forecasts are then compared toevaluate the expected dates for regional and global oil peaks for conventionaloil, all-oils, and all-liquids. The dates of global peaks in the production ofall-oil and all-liquids appear to be reasonably soon, while the oil price thatis needed to support these global production levels continues to rise. Theworld faces serious constraints in its oil supply, which accounts for aboutone-third of total world energy use, and over 90% of the fuel used fortransportation. Readers of this book will gain a thorough understanding of thecritical, but poorly understood, phenomenon of peak oil that has already hadsignificant impacts on society in terms of high oil prices, and which willplace increasing constraints on mankind's supply of energy and economicwell-being in the coming years.

Introduction to Photoelectron Angular Distributions: Theory and Applications (Springer Tracts in Modern Physics #286)
by V. T. DavisThis book provides a comprehensive introduction to photoelectron angular distributions and their use in the laboratory to study light-matter interactions. Photoelectron angular distribution measurements are useful because they can shed light on atomic and molecular electronic configurations and system dynamics, as well as provide information about quantum transition amplitudes and relative phases that are not obtainable from other types of measurements. For example, recent measurements of molecular-frame photoelectron angular distributions have been used to extract photoelectron emission delays in the attosecond range which can provide ultra-sensitive maps of molecular potentials. Additionally, photoelectron angular distribution measurements are an essential tool for studying negative ions. Here, the author presents a detailed, yet easily accessible, theoretical background necessary for experimentalists performing photoelectron angular distribution measurements to better understand their results. The various physical influences on photoelectron angular distributions are revealed through analytical models with the use of angular momentum coupling algebra and spherical tensor operators. The classical and quantum treatments of photoelectron angular distributions are covered clearly and systematically, and the book includes, as well, a chapter on relativistic interactions. Furthermore, the primary methods used to measure photoelectron angular distributions in the laboratory, such as photodetachment electron spectroscopy, velocity-map imaging, and cold target recoil ion momentum spectroscopy, are described. This book features introductory material as well as new insights on the topic, such as the use of angular momentum transfer theory to understand the process of photoelectron detachment in atoms and molecules. Including key derivations, worked examples, and additional exercises for readers to try on their own, this book serves as both a critical guide for young researchers entering the field and as a useful reference for experienced practitioners.
