Taschenbuch. Zustand: Neu. Neuware - The aim of this book is to describe some aspects of the chemistry and chemical ecology which are found in the garden. In the garden there are numerous interactions between plants, the soil and with other organisms in which chemistry plays a central mediating role. The discussion concerns several of the chemically and ecologically interesting compounds that are produced by common ornamental garden plants and vegetables and by the predators that attack them. Many chemists are amateur gardeners and this book is directed at them as well as those with a general interest in the scientific processes involved in the garden.…

Taschenbuch. Zustand: Neu. Neuware - Nanotechnology is a much talked about, and rapidly expanding area of science, which is sometimes little understood. It looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major industry over the coming years. Nanotechnology can be broadly described as developing or exploiting products at nanometre dimensions (i.e. as having one dimension less than 100 nanometres). Such materials have a larger surface area to volume ratio than conventional materials which provides them with an increased level of reactivity, and consequently, toxicity per unit mass. This book sets the subject into context by first of all describing the current range of products containing nano-materials and then looking at the consequences for the environment and human health relating to the introduction of nanoparticles and nano-tubes. Nanotechnology: Consequences for Human Health and the Environment discusses some of the more controversial issues associated with the field including: nanoparticles in the environment, occupational exposure, toxicological properties, human health issues and safety. This authoritative and comprehensive book will be of interest to both scientists and technologists but also to regulators and government. This title is also available in hardback.…

Buch. Zustand: Neu. Neuware - This practical guide to molecular nanotechnology describes the concept of, and provides rules for, building nanostructures from basics. It is, in essence, a fully referenced review, placed in the context of de novo biomolecular design. The book details current approaches to designing novel nanoarchitectures that rely on the structural principles of natural self-assembly patterns. Specific applications are used as examples to highlight particular areas of progress in the field. These include an artificial virus for gene therapy and artificial extracellular matrices for regenerative medicine.Illustrations and references provide an essential support to the text and a special appendix lists who s who in nanodesign . The book has been written to satisfy the demands that motivate the search for and principles that prove to help the design of novel nanostructures. The overall goal is to compile the existing understanding of rules that govern bimolecular self-assembly into a practical guide to molecular nanotechnology. It is written in the shape of a review referenced as fully as permissible within the context of bimolecular design, which forms a general trend throughout. The volume is composed of three core chapters focusing on three prominent topics of applied nanotechnology where the role of nanodesign is predominant. The three key areas from which popular highlights can be drawn are:Employing the genetic repository, DNA, for creating various geometric nanoscale objects and patterns.The empirical pursuit of an artificial virus, a magic bullet in gene therapy -designing artificial extracellular matrices for regenerative medicineSpecific applications that arise from designed nanoscale assemblies as well as fabrication and characterization techniques are of secondary importance and whenever they appear serve as progress and innovation highlights. The book takes an unconventional approach in delivering material of this kind. It does not lead straight to applications or methods as most nanotechnology works tend to do, but instead it focuses on the initial and primary aspect of 'nano' rather than on 'technology'. Nanodesign is unique in its own field - illustrations are essential and the cohort of brilliant bioinspired designs reported to date form a major part of the publication. In addition, key bibliographic references are covered as fully as possible. A special appendix giving a short list of leading world laboratories engaged in bioinspired nanodesign is also included.…
