Available in PDF, EPUB and Kindle. Book excerpt: Flash Photolysis and Pulse Radiolysis: Contributions to the Chemistry of Biology and Medicine presents the interaction of radiation with biomolecules, which is either beneficial o deleterious to life. This book discusses the biochemical reactions that are not radiation-induced by selectively generating certain types of free radicals present in normal metabolic processes. Organized into nine chapters, this book begins with an overview of the principle of both pulse radiolysis and flash photolysis with photoelectric detection. This text then examines the applications of flash photolysis and pulse radiolysis to the chlorophylls, bile pigments, hemoglobin and myoglobin, and the porphyrins. Other chapters consider the carotenoids related to photosynthesis. This book discusses as well the role of proteins in nearly all biological processes, including enzymatic catalysis, muscular contraction, immune protection, mechanical support, and genetic information. The final chapter deals with the structures and importance of radiosensitizers. This book is a valuable resource for chemists and biochemists.

Available in PDF, EPUB and Kindle. Book excerpt: Excited states and free radicals are involved in the normal physiology of living systems, in pathological processes (including lipid peroxidation, inflammation, Parkinson's disease, cancer, and aging), in the mechanisms of drug action, and in the photochemotherapies such as the PUVA therapy for skin diseases and PDT for cancer. This text introduces the reader to this rapidly expanding field, one that lies at the borderlines of physics, chemistry, biology, pharmacology, and medicine. The authors explore in particular how time-resolved spectroscopic methods have found solutions at the molecular level to biological and medical problems. Topics include the nature of excited states and free radicals and the techniques for their study, activated oxygen species, DNA, proteins, carotenoids and photosynthetic reaction centers, photodermatology and melanogenesis, and aspects of cancer related to radio-, chemo-, and photodynamic therapy. Researchers and graduate students in photochemistry, photobiology, photomedicine, radiation chemistry and biology, and cancer therapies will find this book to be of very significant interest.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding chemical reactivity has been the permanent concern of chemists from time immemorial. If we were able to understand it and express it quantitatively there would practically remain no unsolved mystery, and reactions would be fully predictable, with their products and rates and even side reactions. The beautiful developments of thermodynamics through the 19th century supplied us with the knowledge of the way a reactions progresses, and the statistical view initiated by Gibbs has progressively led to an unders tanding closer to the microscopic phenomena. But is was always evident to all that these advances still left our understanding of chemical reactivity far behind our empirical knowledge of the chemical reaction in its practically infinite variety. The advances of recent years in quantum chemistry and statistical mechanics, enhanced by the present availability of powerful and fast compu ters, are very fast changing this picture, and bringing us really close to a microscopic understanding of chemical equilibria, reaction rates, etc.... This is the reason why our Society encouraged a few years ago the initiative of Professor Savo Bratos who, with a group of French colleagues, prepared an impressive study on "Reactivite chimique en phase liquide", a prospective report which was jointly published by the Societe Fran

Available in PDF, EPUB and Kindle. Book excerpt: It is not always the case that the subject of a scientific book and its relevance to everyday li fe are so timely. Photobiology and its si ster subject Radiobiology are now a must for understanding the environment we live in and the impact light, ultraviolet light, and radiation have on all aspects of our life. Photobiology is a true interdisciplinary field. Photobiology research plays a direct role in diverse fields, and a glance at the topics of the symposia covered in this book by over 100 articles shows the breadth and depth of knowledge acquired in fundamental research and its impact on the major issues and applied problems the world is facing. Half a century of photobiology research brought about an understanding of the importance of light to life, both as a necessary source of energy and growth as weIl as its possible dangers. Research in photochemistry and photobiology led to the discoveries of ceIlular repair mechanisms of UV induced damages to DNA and this led to understanding of the effects of hazardous environmental chemieals and mutagenecity , and to the development of genetic engineering. This topic was given due emphasis in several symposia and chapters in this book.

Book excerpt: Radiation Research: Biomedical, Chemical and Physical Perspectives documents the proceedings of the Fifth International Congress of Radiation Research held in Seattle, Washington, 14-20 July 1974. While the focus of the Congress was on fundamental research, there were several well-attended sessions on the practical aspects of radiation research as it relates to radiotherapy, central station power generation by both nuclear fission and fusion, and the environment. This volume contains 126 papers organized into 31 parts. Beginning with a keynote address and a lecture on the time scale in radiobiology, the subsequent contributions cover a wide range of topics presented over several sessions. Topics discussed during these sessions include energy needs, nuclear power, and the environment; prospects for fusion power; technological applications of radiation; human radiobiology; hazards of radiation exposure relative to other environmental agents; the basic physics of the interactions of radiation with matter; particle penetration phenomena; and radiation effects in frozen media.

Book excerpt: Ever since the oil crisis of 1973, researchers in various fields of chemistry have proposed various schemes to conserve energy, as well to convert the sun's abundant and limitless supply of energy to produce chemical fuels (e. g. , hydrogen from water, . •. ). The enthusiasm had no previous parallel in the mid-1970's. Unfortunately, despite the several good proposals, the results have proven - in retrospect - somewhat disappointing from an economic viable point of view. The reasons for the meagre results are manyfold not the least of which are the experimental difficulties encountered in storage systems. Moreover, the lack of a concerted, well orchestrated interdisciplinary approach has been significant. By contrast, the chemical advances made in the understanding of the processes involved in such schemes have been phenomenal. A recent book on this issue ( M. Gratzel, Energy Resources through Photochemistry and Catalysis, 1983) is witness to the various efforts and approaches taken by researchers. In the recent years, many more groups have joined in these efforts, and the number of papers in the lit~rature is staggering ! One of the motives for organizing this NATO Advanced Research Workshop stemmed from our view that it was time to take stock of the accomplishments and rather than propose new schemes, it was time to consider seriously avenues that are most promising.
