Examines the latest applications of photochemistry to generate important intermediates Presenting the latest breakthroughs in the field of organic photochemistry, this book offers tested and proven photochemical approaches to synthesis, creating promising new possibilities and applications for photochemical reactions. It focuses on photoreactions involving an intermediate where mechanistic aspects control the course of the reaction and its synthetic value. Readers will discover new insights into the mechanisms and nature of photo-produced reactive intermediates for organic synthesis as well as the methods to generate them. Moreover, by focusing on highly efficient techniques for producing such species, the authors enable researchers to design and perform photoreactions within the framework of green, sustainable chemistry. Photochemically-Generated Intermediates in Synthesis begins with a discussion of the principles and practice of photo-generated intermediates. Next, the book explores: Photogeneration of carbon-centered radicals Photogeneration of heteroatom-centered radicals Photogeneration of biradicals and radical pairs Photochemical generation of radical ions Photogeneration of carbocations and carbanions Photogeneration of carbenes and nitrenes The book's final chapter is dedicated to the photochemical manipulation of intermediates. Each chapter includes key kinetic data for typical intermediates as well as detailed case examples, giving readers all the tools needed to perform their own photochemical reactions. Comparisons to non-photochemical methods are offered whenever possible. Photochemically-Generated Intermediates in Synthesis sets the stage for greater collaboration among photochemists and synthetic organic chemists, enabling these two research communities to fully leverage photochemistry in order to generate key intermediates needed for a broad range of synthetic reactions in organic chemistry.

In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques.

Organic fertiliser refers to materials used as fertiliser that occur regularly in nature, usually as a by product or end product of a naturally occurring process. Organic fertilisers such as manure have been used in agriculture for thousands of years; ancient farmers did not understand the chemistry involved, but they did recognise the benefit of providing their crops with organic material. Interest in organic farming is growing world-wide as sustainable agricultural practice nowadays. Organic fertilisers are sustained sources of nutrients due to slow release during decomposition. By increasing soil organic matter, organic farming can reinstate the natural fertility of the damaged soil, which will improve the crop productivity to feed the growing population. Organic fertilisers enhance the natural soil processes, which have long-term effects on soil fertility. The book is a very valuable compilation in this direction.

This volume includes the papers presented during the 1st Euro-Mediterranean Conference for Environmental Integration (EMCEI) which was held in Sousse, Tunisia in November 2017. This conference was jointly organized by the editorial office of the Euro-Mediterranean Journal for Environmental Integration in Sfax, Tunisia and Springer (MENA Publishing Program) in Germany. It aimed to give a more concrete expression to the Euro-Mediterranean integration process by supplementing existing North-South programs and agreements with a new multilateral scientific forum that emphasizes in particular the vulnerability and proactive remediation of the Euro-Mediterranean region from an environmental point of view. This volume gives a general and brief overview on current research focusing on emerging environmental issues and challenges and its applications to a variety of problems in the Euro-Mediterranean zone and surrounding regions. It contains over five hundred and eighty carefully refereed short contributions to the conference. Topics covered include (1) innovative approaches and methods for environmental sustainability, (2) environmental risk assessment, bioremediation, ecotoxicology, and environmental safety, (3) water resources assessment, planning, protection, and management, (4) environmental engineering and management, (5) natural resources: characterization, assessment, management, and valorization, (6) intelligent techniques in renewable energy (biomass, wind, waste, solar), (7) sustainable management of marine environment and coastal areas, (8) remote sensing and GIS for geo-environmental investigations, (9) environmental impacts of geo/natural hazards (earthquakes, landslides, volcanic, and marine hazards), and (10) the environmental health science (natural and social impacts on Human health). Presenting a wide range of topics and new results, this edited volume will appeal to anyone working in the subject area, including researchers and students interested to learn more about new advances in environmental research initiatives in view of the ever growing environmental degradation in the Euro-Mediterranean region, which has turned environmental and resource protection into an increasingly important issue hampering sustainable development and social welfare.
