Book Description
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

Book Description
The last decade has seen a huge interest in green organic chemistry, particularly as chemical educators look to "green" their undergraduate curricula. Detailing published laboratory experiments and proven case studies, this book discusses concrete examples of green organic chemistry teaching approaches from both lecture/seminar and practical perspectives. The experienced contributors address such topics as the elimination of solvents in the organic laboratory, organic reactions under aqueous conditions, organic reactions in non-aqueous media, greener organic reagents, waste management/recycling strategies, and microwave technology as a greener heating tool. This reference allows instructors to directly incorporate material presented in the text into their courses. Encouraging a stimulating organic chemistry experience, the text emphasizes the need for undergraduate education to: Focus on teaching sustainability principles throughout the curriculum Be flexible in the teaching of green chemistry, from modification of an existing laboratory experiment to development of a brand-new course Reflect modern green research areas such as microwave reactivity, alternative reaction solvents, solvent-free chemistry, environmentally friendly reagents, and waste disposal Train students in the "green chemistry decision-making" process Integrating recent research advances in green chemistry research and the Twelve Principles of Organic Chemistry into the lecture and laboratory environments, Green Organic Chemistry in Lecture and Laboratory highlights smaller, more cost-effective experiments with minimized waste disposal and reduced reaction times. This approach develops a fascinating and relevant undergraduate organic laboratory experience while focusing on real-world applications and problem-solving.

Book Description
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

Book Description
Details the water research applications of nanotechnology in various areas including environmental science, remediation, membranes, nanomaterials, and water treatment At the nano size, materials often take on unique and sometimes unexpected properties that result in them being ‘tuned’ to build faster, lighter, stronger, and more efficient devices and systems, as well as creating new classes of materials. In water research, nanotechnology is applied to develop more cost-effective and high-performance water treatment systems, as well as to provide instant and continuous ways to monitor water quality. This volume presents an array of cutting-edge nanotechnology research in water applications including treatment, remediation, sensing, and pollution prevention. Nanotechnology applications for waste water research have significant impact in maintaining the long-term quality, availability, and viability of water. Regardless of the origin, such as municipal or industrial waste water, its remediation utilizing nanotechnology can not only be recycled and desalinized, but it can simultaneously detect biological and chemical contamination. Application of Nanotechnology in Water Research describes a broad area of nanotechnology and water research where membrane processes (nanofiltration, ultrafiltration, reverse osmosis, and nanoreactive membranes) are considered key components of advanced water purification and desalination technologies that remove, reduce, or neutralize water contaminants that threaten human health and/or ecosystem productivity and integrity. Various nanoparticles and nanomaterials that could be used in water remediation (zeolites, carbon nanotubes, self-assembled monolayer on mesoporous supports, biopolymers, single-enzyme nanoparticles, zero-valent iron nanoparticles, bimetallic iron nanoparticles, and nanoscale semiconductor photocatalysts) are discussed. The book also covers water-borne infectious diseases as well as water-borne pathogens, microbes, and toxicity approach.

Book Description
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.
