    Natural products present in the plant and animal kingdom offer a huge diversity of chemical structures which are the result of biosynthetic processes that have been modulated over the millennia through genetic effects. With the rapid developments in spectroscopic techniques and accompanying advances in high-throughput screening techniques, it has become possible to isolate, and then determine the structures and biological activity of natural products rapidly, thus opening up exciting new opportunities in the field of new drug development to the pharmaceutical industry. The series also covers the synthesis or testing and recording of the medicinal properties of natural products.

  • Next Generation of International Chemical Additives

    A Critical Review of Current US Patents
    • 1 Edición
    • Thomas F. DeRosa
    • Inglés
    The objective is writing Next Generation Chemical Additives to identify the next generation chemical additives for eight selected industries. The text will also provide methods for their preparation, additive treatment levels, and testing methods to evaluate additive performance. To ensure optimum performance of materials and products, chemists, formulators, and blenders must be provided with the most current information on existing chemical additives. It is even more essential that corporate operations officers can easily identify the next generation of chemical additives. In addition to this a critical comparison will be given with the existing additives.

  • Analysis and Risk of Nanomaterials in Environmental and Food Samples

    • Inglés
    The application of nanotechnology in different consumer products has delivered new products with highly desirable properties, but at same time has opened a new window for a wide group of emerging contaminants and a new type of human exposure which needs to be assessed. Most of the current human toxicological information on nanomaterials comes from nano-sized particles in air, and their effects via inhalation. Other routes of human exposure, such as water and food, and the effects on human health and the environment have been less studied. It is the recent research in these areas that is highlighted here in one of the first books covering the analysis and ecotoxicological evaluation of nanomaterials in food and the environment, with both matrices being of considerable interest. In addition to providing a global summary of recent research, this book shows how widely used chromatographic and spectroscopic methods can be added to the analytical arsenal of microscopic techniques that have commonly been used to characterize nanomaterials.

    • Amadeo Rodriguez Fernandez-Alba
    • Inglés
    New developments in mass spectrometry have allowed routine identification and lowered limits of detection at levels only imagined a decade ago. Thousands of contaminants and residues in the food supply and the environment are now being reported. Between 2005 and 2010, more than 5,000 publications covering TOF-MS and environmental and food analysis were published, showing the importance of the technique in these applications. This book covers the basic principles of method development in GC- and LC-TOF-MS as well as the main operational parameters related to TOF-MS. The second part focuses on the relevant environmental applications, including quality control aspects as well as data collection. The third part is devoted to relevant applications in food analysis, including validation procedures for screening analysis as well as relevant databases.
