|Photochromism: Molecules and Systems

List price: $315.00
Photochromism is simply defined as the light induced reversible change of colour. The field has developed rapidly during the past decade as a result of attempts to improve the established materials and to discover new devices for applications.
As photochromism bridges molecular, supramolecular and solid state chemistry, as well as organic, inorganic and physical chemistry, such a treatment requires a multidisciplinary approach and a broad presentation. The first edition (1990) provided an enormous amount of new concepts and data, such as the presentation of main families based on the pericyclic reaction mechanism, the review of new families, some bimolecular photocycloadditions and some promising systems.
This new edition provides an efficient entry into this flourishing field, with the core content retained from the original work to provide a basic introduction into the different subjects.
*Second edition of a work first published in 1990, now revised due to constant development of research.
*Including updated lists of references (1989-2001), offering immediate access to recent developments.
*Providing great basic interest and high application potential bringing scientists together from chemistry, physics and engineering.
|Photochemical Purification of Water and Air: Advanced Oxidation Processes (AOPs) - Principles, Reaction Mechanisms, Reactor Concepts
Lowest new price: $4,671.14

Author: Thomas Oppenl?nder
While the treatment of water and exhaust gas using ultraviolet (UV) light offers both ecological and economic advantages, information on photo-initiated advanced oxidation technologies (AOTs) has been dispersed among various journals and proceedings until now. This authoritative and comprehensive handbook is the first to cover both the photochemical fundamentals and practical applications, including a description of advanced oxidation processes (AOPs) and process engineering of suitable photoreactors. The author presents various real-world examples, including economic aspects, while many references to current scientific literature facilitate access to current research topics relevant for water and air industries. Throughout, over 140 detailed figures visualize photochemical and photophysical phenomena, and help in interpreting important research results.
From the foreword by James R. Bolton (President of Bolton Photosciences Inc., Executive Director of the International Ultraviolet Association (IUVA)): "Prof. Oppenl?nder is well qualified to write about the AOPs/AOTs, since he has contributed to this literature in a very significant manner. This book will be of considerable value to graduate students, science and engineering faculty, scientists, process engineers and sales engineers in industry, government regulators and health professionals."

|Photoreactive Polymers: The Science and Technology of Resists
Lowest new price: $26.00
Lowest used price: $20.61
List price: $150.00
Author: Arnost Reiser
Basic mechanisms and applications of photoresist chemistry in semiconductor device manufacturing, lithography, chemical engineering, and the graphic arts are discussed in this book. It gives a balanced view of the subject as it now stands and at the same time promotes an understanding of the perennial challenge of material science to meet the demands of new technology by the successful design of new materials. The presentation of the text follows the history of the subject, and the generic resist systems are described approximately in the order in which they made their appearance. This approach maintains the logic of technical development where a new material emerges in response to some deficiency in its historic precursor. The chapters dealing with the resists are interspersed with sections on the related background in photophysics, radiation chemistry, and image science. The text will be of benefit to engineers, chemists and materials scientists in the semiconductor, graphic arts, and polymer photography industries, and graduate students in chemical engineering and electronics.
|Physics and Chemistry of Photochromic Glasses (Laser & Optical Science & Technology)
Lowest new price: $83.94
Lowest used price: $60.00
List price: $209.95
Author: Alexander V. Dotsenko
Photochromic glasses are among the most widespread types of glasses, due largely to their popular use in sunglasses. These glasses are used not only in sunglasses, but also in various opto-electronic devices that have been developed and produced throughout the world. Until now, information about photochromic glasses has been widely dispersed in the literature, much of which was published in Russian and therefore of limited accessibility to the Western world. Physics and Chemistry of Photochromic Glasses brings together the combined knowledge and understanding of photochromic glasses from these publications. Coverage includes the structure, optical properties, coloration and bleaching mechanisms, technology, and metrology of these interesting materials.
|Thermoluminescence of Solids (Cambridge Solid State Science Series)
Lowest new price: $73.78
Lowest used price: $55.43
List price: $98.00
Author: S. W. S. McKeever
McKeever gives us a comprehensive survey of thermoluminescence, an important, versatile, and widely-used experimental technique. Bringing together previously isolated specialized approaches, he stresses the importance of the solid state aspects of the phenomenon and links these to applications in dating, dosimetry, and geology. The book contains chapters on analysis and special properties, on instrumentation, and on the variety of defect reaction--using the alkali halides and SiO2 as examples--that can take place within a material to yield thermoluminescence. Three chapters concerning applications discuss the features of the solid state reactions to explain some of the properties observed in practice.

Photodynamic therapy (PDT) is a ground breaking medical technique which uses lasers to activate light-sensitive chemicals to treat cancer and other diseases without resorting to surgery. For the first time, Chemical Aspects of Photodynamic Therapy introduces in an accessible way the physics, chemistry and biology behind the technique. This highly authoritative account of the account of the rapidly developing field of PDT explores its chemical basis, while presenting information in its historical context. Haematoporphyrin derivative is considered in detail, together with the new 'second generation' photosensitisers , such as chlorins, bacteriochlorins and phthalocyanines. Photosensitisers which are currently in clinical trials are compared and reference is made to new light sources, biological and clinical findings, and prospects for future developments.
This book is essential reading for new students and researchers alike studying PDT. It is recommended particularly for photochemists, as well as photobiologists and clinicians.
