Buch. Zustand: Neu. Neuware - Life-cycle assessment of new energy solutions plays an important role in discussions about global warming mitigation options and the evaluation of concrete energy production and conversion installations.

Buch. Zustand: Neu. Neuware - Nanoscience is one of the most exciting scientific disciplines as it is concerned with materials and systems, which exhibit novel and significantly improved physical, chemical and biological properties due to their small nanoscale size. It stretches across the whole spectrum of modern science including medicine and health, physics, engineering and chemistry. Providing a deep understanding of the behaviour of matter at the scale of individual atoms and molecules, it takes a crucial step towards future applications of nanotechnology. The remarkable improvements in both theoretical methods and computational techniques make it possible for computational nanoscience to achieve a new level of accuracy. Computational nanoscience is now a discipline capable of leading and guiding experimental efforts. Computational Nanoscience addresses modern challenges in computational science, within the context of the rapidly evolving field of nanotechnology. It satisfies the need for a comprehensive, yet concise and up-to-date, survey of new developments and applications presented by the world's leading academics. It documents major, recent advances in scientific computation, mathematical models and theory development that specifically target the applications in nanotechnology. Suitable for theoreticians, experimental researchers and students, the book shows readers what computational nanoscience can achieve, and how it may be applied in their own work. The twelve chapters cover topics including the concepts behind recent breakthroughs in nanoscience, the development of cutting edge simulation tools, and the variety of new applications.

Buch. Zustand: Neu. Neuware - Scientists are conducting active research in different fields of engineering, science and technology by using Green Chemistry Principles to devise new, environmentally friendly processes. A Handbook of Applied Biopolymer Technology: Synthesis, Degradation and Applications reflects these developments in an up-to-date, coherent and objective set of chapters by international experts from academia who are world leaders in research and technology in sustainability and biopolymer and biodegradable polymer synthesis, characterisation, testing and use. The handbook highlights the following areas: green polymers; biopolymers and bionanocomposites; biodegradable and injectable polymers; biodegradable polyesters; synthesis and physical properties; discovery and characterization of biopolymers; degradable bioelastomers, lactic acid based biodegradable polymers; enzymatic degradation of biodegradable polymers; biodegradation of polymers in the composting environment; recent development in biodegradable polymers; research and applications and biodegradable foams. The book is aimed at technical, research-orientated and marketing people in industry, universities and institutions. Readers will gain a comprehensive and consolidated overview of the immense potential and ongoing research in bio-based and biodegradable polymer science, engineering and technology to make the world greener.

Buch. Zustand: Neu. Neuware - This book presents the current approaches for insect pest control as a 'green' alternative to classical and more toxaic agrochemicals. An overview of the recent advances in insecticide chemistry is also included, which will be of interest to a vast group of researchers - agrochemists, biochemists, chemists and toxicologists. The combination of both chemical and toxicological aspects of insecticides is unique and the book includes contributions from synthetic chemists, entomologists, environmentalists and toxicologists giving it wide appeal. Throughout the book, the different approaches that involve 'greener chemicals' are emphasized. The book is divided into 9 chapters, each considering the state of art of each family of insecticides, together with future expectations. Each chapter gives a description of useful biorational insecticides, highlighting environmentally-friendly processes and then the mode of action is fully-described, emphasizing selectivity towards targeted species. Finally, for every family of compounds, their environmental effects (toxicity, bioaccumulation and metabolism) is considered, comparing them to classical insecticides, including human and environmental risk assessments. In addition the formulation, dispersal and persistence in the environment are covered as key aspects in developing greener agrochemicals. The book also includes a general introduction to entomology, with special emphasis on those insects that act as vectors in the spread of diseases. Insects that may be potential pests against humans and livestock are included, focusing on their life cycles, and physiology, as a logical comprehension of mode of action of insecticides. In addition there is a chapter on classical insecticides (covering both, approaches prior to the chemical era, and classical chemical insecticides, organochlorinated, organophosphorus, and carbamates) for comparison with current trends in pest control. The negative environmental effects that such insecticides have caused in nature, such as poisonings, bioaccumulation or toxic effects are highlighted. It is hoped that the use of more specific agrochemicals and approaches may avoid, or at least considerably reduce such severe and irreversible effects in nature. The insecticides covered are considered from numerous points of views: chemistry, toxicological profile, risk assessment, legal status, environmental behaviour and selectivity. The most important families of currently used insecticides are covered and critical discussions about future perspectives are included with frequent comparisons to classical insecticides. The following topics are covered in the book, as greener alternatives to classical insecticides: ' Pyrethrins and pyrethroids ' Neonicotinoids ' Spynosins ' Insect growth regulators ' Botanical insecticides ' Microbial insecticides ' Integrated Pest Management Programs (IPM).

Buch. Zustand: Neu. Neuware - This book is the first to comprehensively cover this interesting and rapidly spreading topic, namely the use of visible light and photosensitising agents for controlling the population of microbial pathogens. Edited by two pioneers in the application of this technique for addressing both medical and environmental issues, and bringing together the foremost practitioners internationally in this field, this up-to-date account will address basic/mechanistic aspects followed by an exhaustive coverage of the current medical applications and environmentally friendly approaches. The book will be an indispensable resource for students and professionals working in fields relating to photochemistry, environmental science and medical applications for photodynamic therapy.
