Advances in Fluorine Science presents critical multidisciplinary overviews for areas in which fluorine and fluoride compounds have a decisive impact. The individual volumes of Advances in Fluorine Science are thematic, addressing comprehensively both the science and applications on topics including the Environment, Green chemistry, Medicine, Health & Life Sciences, New Technologies & Materials Science, Energy and the Earth Sciences. For each subject the contributors will clearly inform the reader on the nature of the problem (if any) and on the solutions, combining knowledge from different scientific disciplines, that have been proposed to solve each issue. This volume covers a wide scope of important issues about our atmospheric environment and contains contributions from both chemists and environmental scientists. Articles review the origin of fluorine-emissions either from natural or anthropogenic origin; the chemistry of fluorine- and halogen-based species in the atmosphere; the monitoring and characterization of atmospheric pollutants; new generations of halocarbons and improved destruction procedures of banned CFCs; the role of fluorides within both our geosphere: volcanic magmas and natural fluorine emissions, and effects on our biosphere: life cycle, plants and animals. * Examines the role of fluorine and fluoride products in our environment: from the geosphere to the atmosphere through the biosphere * Discusses the efforts of scientists and industry groups towards the improvement of environmental and sustainability issues * Multidisciplinary contributions from chemists, geologists, biologists, environmentalists and industry staffs

Fluorine and Health presents a critical multidisciplinary overview on the contribution of fluorinated compounds to resolve the important global issue of medicinal monitoring and health care. The involved subjects are organized in three thematic parts devoted to Molecular Imaging, Biomedical Materials and Pharmaceuticals. Initially the key-position of partially fluorinated low molecular weight compounds labelled either with the natural 19F-isotope for Magnetic Resonance Imaging (MRI) or labelled with the radioactive [18F]-isotope for Positron Emission Tomography (PET) is highlighted. Both non-invasive methods belong to the most challenging in vivo imaging techniques in oncology, neurology and in cardiology for the diagnosis of diseases having the highest mortality in the industrialized countries. The manifold facets of fluorinated biomaterials range from inorganic ceramics to perfluorinated organic molecules. Liquid perfluorocarbons are suitable for oxygen transport and as potential respiratory gas carriers, while fluorinated polymers are connected to the pathology of blood vessels. Another important issue concerns the application of highly fluorinated liquids in ophthalmology. Moreover, fluorine is an essential trace element in bone mineral, dentine and tooth enamel and is applied for the prophylaxis and treatment of dental caries. The various origins of human exposure to fluoride species is detailed to promote a better understanding of the effect of fluoride species on living organisms.Medicinally relevant fluorinated molecules and their interactions with native proteins are the main focus of the third part. New molecules fluorinated in strategic position are crucial for the development of pharmaceuticals with desired action and optimal pharmacological profile. Among the hundreds of marketed active drug components there are more than 150 fluorinated compounds. The chapters will illustrate how the presence of fluorine atoms alters properties of bioactive compounds at various biochemical steps, and possibly facilitate its emergence as pharmaceuticals. Finally the synthetic potential of a fluorinase, the first C-F bond forming enzyme, is summarized. New approach of topics involving chemistry, biology and medicinal techniques Transdisciplinar papers on fluoride products Importance of fluoride products in health Updated data on specific topics

Water is the driving force of all nature. This old quote from Leonardo da Vinci reminds us that without water life is simply not possible. As a consequence, water is probably the most important wealth for humanity. In spite of this, drinking water is still polluted by man-made toxicals gathered by waters in soils and the atmosphere. This book presents advanced methods to clean water and air. Chapters also focus on biofuels, greenhouse gases and genetically modified crops.

Advances in Fluorine Science is a new book series presenting critical multidisciplinary overviews on areas in which fluorine and fluoride compounds have a decisive impact. The individual volumes of Advances in Fluorine Science are thematic, addressing comprehensively both the science and applications on topics including the Environment, Green chemistry, Medicine, Health & Life Sciences, New Technologies & Materials Science, Energy and the Earth Sciences. In the present volume, the key-position of fluoro-products in agriculture is reviewed, since a large percentage of agro-chemicals and pesticides contain at least one fluorine atom. However, improvements in the use of fluorine-based products in agrochemicals cannot be developed without taking into consideration a safer environment, on both levels of greener synthesis routes and a reduction of the negative impact on plants and organisms. Within this scope, fluorine has a very peculiar place, since its high reactivity yields several advantages, for instance in by-passing various polluting multi-step reactions. Fluorine-based materials are reviewed as efficient tools for protecting our cultural heritage. Also using up-to-date techniques such as ion beam analysis, this element can help relative dating applications, ranging from burial durations of archaeological bones and teeth to the determination of exposure ages of meteorites on the Antarctic ice shield. Providing an original approach of the complex relationships between chemistry and the environment Reviewing the key-position of fluoro-products in agriculture Multidisciplinary contributions from chemists, geologists, biologists, environmentalists and industry staffs
