Book Description
Photochemistry of Proteins and Nucleic Acids focuses on the effects of ultraviolet and visible radiations on proteins and nucleic acids. The book first discusses some principles of photochemistry, including the laws of photochemistry and factors influencing photochemical reactions in solutions. The text describes absorption and luminescence spectra of nucleoproteins and their components, including principal absorbing groups in proteins, nucleic acids, and nucleoproteins. The selection also highlights the action of ultraviolet light on proteins; photochemical and photosensitized inactivation of enzymes; and the photochemistry of purine and pyrimidine derivatives. The text also discusses nucleic acids and oligo- and polynucleotides. Topics include photochemical degradation of nucleic acid; kinetics of biological inactivation of nucleic acids; nucleoproteins; and reversibility of nucleic acid photolysis. The book also encompasses the inactivation of viruses, including inactivation studies with a plant virus, bacteriophages, and photochemically produced vaccines. The text also presents some problems in photobiology and some techniques in photochemistry. The text is a good source of information for readers interested in the study of proteins and nucleic acids.Based on the standards and codes from Fo

Book Description
Presents the state of the technology, from fundamentals to new materials and applications Today's electronic devices, computers, solar cells, printing, imaging, copying, and recording technology, to name a few, all owe a debt to our growing understanding of the photophysics and photochemistry of polymeric materials. This book draws together, analyzes, and presents our current understanding of polymer photochemistry and photophysics. In addition to exploring materials, mechanisms, processes, and properties, the handbook also highlights the latest applications in the field and points to new developments on the horizon. Photochemistry and Photophysics of Polymer Materials is divided into seventeen chapters, including: Optical and luminescent properties and applications of metal complex-based polymers Photoinitiators for free radical polymerization reactions Photovoltaic polymer materials Photoimaging and lithographic processes in polymers Photostabilization of polymer materials Photodegradation processes in polymeric materials Each chapter, written by one or more leading experts and pioneers in the field, incorporates all the latest findings and developments as well as the authors' own personal insights and perspectives. References guide readers to the literature for further investigation of individual topics. Together, the contributions represent a series of major developments in the polymer world in which light and its energy have been put to valuable use. Not only does this reference capture our current state of knowledge, but it also provides the foundation for new research and the development of new materials and new applications.

Book Description
Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine. This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts: * Basic principles in photopolymerization reactions * Radical photoinitiating systems * Nonradical photoinitiating systems * Reactivity of the photoinitiating system The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved. The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.

Book Description
Global climate change affects productivity and species composition of freshwater and marine aquatic ecosystems by raising temperatures, ocean acidification, excessive solar UV and visible radiation. Effects on bacterioplankton and viruses, phytoplankton and macroalgae have farreaching consequences for primary consumers such as zooplankton, invertebrates and vertebrates, as well as on human consumption of fish, crustaceans and mollusks. It has affected the habitation of the Arctic and Antarctic oceans the most so far. Increasing pollution from terrestrial runoff, industrial, municipal and household wastes as well as marine transportation and plastic debris also affect aquatic ecosystems.

Book Description
The goals of the science of photobiology can be divided into four cate gories: to develop (1) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and phys icists, because photobiology is a truly multidisciplinary science. While a multidisciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for the oretical or practical use. Photochemical and Photobiological Reviews continues to provide in-depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger sci entists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate.
