    Volume 5 in this series spans a variety of topics including terpene synthesis, amino acid synthesis, and combinatorial methods for generation of structural diversity. The first chapter has been contributed by Trond Hansen and Professor Yngve Strenstrøm of the Agricultural University of Norway, and surveys naturally occurring cyclobutanes. As well as providing a review of representative syntheses and synthetic strategies for the introduction of cyclobutane into target molecules, the number of rings contained in the natural product is also discussed in logical order.The following chapter, written by Professor Timothy Brocksom, his wife Ursula, and a number of co-workers from the Federal University of São Carlos, surveys the synthesis of higher terpenes by the use of Diels-Alder reaction. A useful review of the current literature in this field is provided, together with 79 references and footnotes.The third chapter, written by Michael G. Natchus and Xinrong Tian of Procter & Gamble Pharmaceuticals, covers recent advances in the synthesis of unnatural amino acids. Three of the major asymmetric methods are discussed and grouped according to the chemistry involved.The fourth and final chapter has been contributed by Professor Dennis Wright of the University of Florida, and other co-workers. A review of the combinatorial chemistry methods currently available for lead discovery in pharmaceutical research is provided in this chapter, as well as discussions on the methods based on natural products and an overview of the complexity building techniques.

  • Fine Chemicals Manufacture

    Technology and Engineering
    • 1st Edition
    • A. Cybulski + 3 more
    • English
    The sector of fine chemicals, including pharmaceuticals, agrochemicals, dyes and pigments, fragrances and flavours, intermediates, and performance chemicals is growing fast. For obvious reasons chemistry is a key to the success in developing new processes for fine chemicals. However, as a rule, chemists formulate results of their work as recipes, which usually lack important information for process development. Fine Chemicals Manufacture, Technology and Engineering is intended to show what is needed to make the recipe more useful for process development purposes and to transform the recipe into an industrial process that will be safe, environmentally friendly, and profitable.The goal of this book is to form a bridge between chemists and specialists of all other branches involved in the scale-up of new processes or modification of existing processes with both a minimum effort and risk and maximum profit when commercializing the process. New techniques for scale-up and optimization of existing processes and improvements in the utilization of process equipment that have been developed in recent years are presented in the book.

  • Paradoxes in Geology

    • 1st Edition
    • U. Briegel + 1 more
    • English
    An interesting volume presenting the papers collected for the Festschrift "Paradoxes in Modern Geology" in honor of Professor Ken Jinghwa Hsu on the occasion of his 70th birthday.Paradox, as defined in a dictionary, is a statement contrary to accepted opinion. That a broad discussion of paradoxes is fruitful for the advancement of science in general, and geosciences in particular, has been amply demonstrated by Professor Hsu throughout his distinguished career. Not only has he propelled the geoscience community forward with his controversial statements, a number of his former students, who are currently in key positions at universities and in industry, are influencing in a similar open minded way the present day thinking. The wide scope this reasoning encompasses is demonstrated by the contributions to this book, delineating paradoxes and problems in the fields of tectonics, basic and applied geosciences, petrology, paleoceanography, paleoclimatology and paleogeography, kinematics and modelling.

  • Nitrogen in the Environment: Sources, Problems and Management

    • 1st Edition
    • R.F. Follett + 1 more
    • English
    Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture.Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment.The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

  • Oxide-based Systems at the Crossroads of Chemistry

    • 1st Edition
    • Volume 140
    • C. Colella + 2 more
    • English
    This volume includes papers presented at the second International Workshop on Oxide-based Systems at the Crossroads of Chemistry, held at Villa Olmo in Como, Italy, 8-11 October.The selected papers present the highlights of recent research in the field of oxide structure. A wide range of oxidic materials, including real oxides, zeolites and layer-structured systems, is considered and described in terms of preparation methods, structural characterization and the relation between active sites, structure and catalytic properties. The application of the most powerful simulation and physical-chemical techniques show their usefulness in discovering and explaining structural and dynamic properties of complex materials. Moreover the development of sophisticated spectroscopical and analytical techniques are shown to significantly improve the growth of surface oxide science, generating new tools for the knowledge of catalyst structure and reaction mechanisms. An interesting feature is the inclusion of papers which show the mutual roles of experiment and theoretical models.
