Nano and Microsensors for Chemical and Biological Terrorism Surveillance - - Bog - Royal Society of Chemistry - Plusbog.dk

The 9/11 attack on US soil has inadvertently heightened the need for preparation for other potential means of terrorist attack. In particular, both biological and chemical warfare have been at the top of the priority list for most governmental agencies as these reagents can be covertly prepared and disseminated to result in both widespread fear and casualty. Among many others, one primary preventive step in preparing for the above attacks is to establish a network for efficient surveillance and rapid detection such that an appropriate response to such attacks can be timely and effective. Over the years, primarily due to technological advances, both chemical and biological agents that are able to inflict mass destructions are becoming more diverse and complex. Subsequently, improvement of sensing devices for rapid and sensitive detection should also be made to keep pace with these engineered or emerging threat agents. Of particular interest, the ability to encompass advances in micro and nanofabrication techniques to enable sensing devices are especially of interest as they have been shown to offer desired advantages such as improved and enhanced functionality, increased efficiency and speed in their readout, reduction in their fabrication cost, and also reduced reagent consumption. Numerous innovative and exciting reports which took advantage of these techniques for both chemical and biological sensing have appeared over the last decade. This unique book is the only current publication that provides readers with a brief, yet concise, collection of the latest advances in chemical and biological agent detection and/or their surveillance. It compiles and gives in-depth detail on several detection schemes so that the reader can be provided with a general sense of these micro and nanoscale sensing systems and platforms. The book covers both well established and "next-generation" micro- and nano-scale sensors and/or sensing platforms. Sensors or sensing platforms covered range from the novel utilization of nanotubes, cantilevers, nano and/or microsized pores, engineered whole cell, to polymeric transistors for sensing purposes. As a result of these advances there has been a synergistic marriage of a myriad of techniques, ranging from chemical, engineering and biological, for the development of sensors, which was once traditionally thought to be reserved for the immunologists. The enabling of these new technologies will result in a much improved sensing network for the detection and surveillance of both chemical and biological warfare agents.The book also contains chapters from leading experts in the field of chemical and biological sensing platforms and will be invaluable reading for anybody in this field.

Microbiology for the Analytical Chemist - R K Dart - Bog - Royal Society of Chemistry - Plusbog.dk

Science and Art - - Bog - Royal Society of Chemistry - Plusbog.dk

Science and art are increasingly interconnected in the activities of the study and conservation of works of art. Science plays a key role in cultural heritage, from developing new analytical techniques for studying the art, to investigating new ways of preserving the materials for the future. For example, high resolution multispectral examination of paintings allows art historians to view underdrawings barely visible before, while the use of non-invasive and micro-sampling analytical techniques allow scientists to identify pigments and binders that help art conservators in their work. It also allows curators to understand more about how the artwork was originally painted. Through a series of case studies written by scientists together with art historians, archaeologists and conservators, Science and Art: The Painted Surface demonstrates how the cooperation between science and humanities can lead to an increased understanding of the history of art and to better techniques in conservation. The examples used in the book cover paintings from ancient history, Renaissance, modern, and contemporary art, belonging to the artistic expressions of world regions from the Far East to America and Europe. Topics covered include the study of polychrome surfaces from pre-Columbian and medieval manuscripts, the revelation of hidden images below the surface of Van Gogh paintings and conservation of acrylic paints in contemporary art. Presented in an easily readable form for a large audience, the book guides readers into new areas uncovered by the link between science and art. The book features contributions from leading institutions across the globe including the Metropolitan Museum of Art, New York; Art Institute of Chicago; Getty Conservation Institute; Opificio delle Pietre Dure, Firenze; National Gallery of London; Tate Britain; Warsaw Academy of Fine Art and the National Gallery of Denmark as well as a chapter covering the Thangka paintings by Nobel Prize winner Richard Ernst.

Chemical Reactions and Processes under Flow Conditions - - Bog - Royal Society of Chemistry - Plusbog.dk

Chemical Reactions and Processes under Flow Conditions - - Bog - Royal Society of Chemistry - Plusbog.dk

Pharmaceutical and fine chemical products are typically synthesised batchwise which is an anomaly since batch processes have a series of practical and economical disadvantages. On the contrary, flow continuous processes present a series of advantages leading to new ways to synthesise chemical products. Flow processes - * enable control reaction parameters more precisely (temperature, residence time, amount of reagents and solvent etc.), leading to better reproducibility, safer and more reliable processes * can be performed more advantageously using immobilized reagents or catalysts * improve the selectivity and productivity of the process and possibly even the stability of the catalyst * offer opportunities for heat exchange and energy conservation as well as an easy separation and recycling of the reactants and products by adequate process design * achieve multistep syntheses by assembling a line of reactors with minimum or no purification in between two reaction steps * can be assured by facile automation * scale-up can be easily conducted by number-up With all the new research activity in manufacturing chemical products, this comprehensive book is very timely, as it summarises the latest trends in organic synthesis. It gives an insight into flow continuous processes, outlining the basic concepts and explaining the terminology of, and systems approach to, process design dealing with both homogeneous and heterogeneous catalysis and mini- or micro-reactors. The book contains case studies, extensive bibliographies and reference lists in each chapter to enable the reader to grasp the contents and to go on to more detailed texts on specific subjects if desired. The book is written by both organic chemists and engineers giving a multidisciplinary vision of the new tools and methodologies in this field. It is essential reading for organic chemists (in industry or academia) working alongside chemical engineers or who want to undertake chemical engineering projects. It will also be of interest for chemical engineers to see how basic engineering concepts are applied in modern organic chemistry.
