This book was developed with the goal of providing an easily understood text for those users of the scanning electron microscope (SEM) who have little or no background in the area. The SEM is routinely used to study the surface structure and chemistry of a wide range of biological and synthetic materials at the micrometer to nanometer scale. Ease-of-use, typically facile sample preparation, and straightforward image interpretation, combined with high resolution, high depth of field, and the ability to undertake microchemical and crystallographic analysis, has made scanning electron microscopy one of the most powerful and versatile techniques for characterization today. Indeed, the SEM is a vital tool for the characterization of nanostructured materials and the development of nanotechnology. However, its wide use by professionals with diverse technical backgrounds-including life science, materials science, engineering, forensics, mineralogy, etc., and in various sectors of government, industry, and academia-emphasizes the need for an introductory text providing the basics of effective SEM imaging.A Beginners' Guide to Scanning Electron Microscopy explains instrumentation, operation, image interpretation and sample preparation in a wide ranging yet succinct and practical text, treating the essential theory of specimen-beam interaction and image formation in a manner that can be effortlessly comprehended by the novice SEM user. This book provides a concise and accessible introduction to the essentials of SEM includes a large number of illustrations specifically chosen to aid readers' understanding of key concepts highlights recent advances in instrumentation, imaging and sample preparation techniques offers examples drawn from a variety of applications that appeal to professionals from diverse backgrounds.

The phylum Mollusca is the second largest group of animals and occur in virtually all habitats. Many non-marine molluscs are threatened with more recorded extinctions than all tetrapod vertebrates combined. This two-volume set will provide the first general account of molluscs in decades and will include hundreds of colour figures. General chapters bring together a diverse and extensive literature, while taxon chapters provide overviews of their evolution, phylogeny and classification as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record, and their natural history.

A thought-provoking series that chronicles the discussions, disputes, and debates that have divided scientists and advanced science through the ages. The origins of humanity? The causes of homosexuality? Experimentation on humans and animals? In both theory and practice, science is riven by controversy. Always has been, always will be. Controversies in Science reveals the history of humanity's disputatious pursuit of truth-the passions, the polemics, and the partisanship. ABC-CLIO's Controversies in Science series examines some of the greatest debates in the history of science's quest for truth. Edited by top scientists, philosophers, and historians, the titles explore fields as diverse as cosmology, genetics, evolution, psychiatry, and the fascinating and speculative study of extraterrestrial biology. Who are we? Where do we come from? And what limits should we place on the pursuit of answers to these questions? The truth is out there. But what routes have we taken? What routes should we take? Controversies in Science offers a road map.
