Much of this book was written during a sabbatical visit by J. C. H. S. to the Max Planck Institute in Stuttgart during 1991. We are therefore grateful to Professors M. Ruhle and A. Seeger for acting as hosts during this time, and to the Alexander von Humbolt Foundation for the Senior Scientist Award which made this visit possible. The Ph. D. work of one of us (J. M. Z. ) has also provided much of the background for the book, together with our recent papers with various collaborators. Of these, perhaps the most important stimulus to our work on convergent-beam electron diffraction resulted from a visit to the National Science Foundation's Electron Microscopy Facility at Arizona State University by Professor R. H(lJier in 1988, and from a return visit to Trondheim by J. C. H. S. in 1990. We are therefore particularly grateful to Professor H(lJier and his students and co-workers for their encouragement and collaboration. At ASU, we owe a particular debt of gratitude to Professor M. O'Keeffe for his encouragement. The depth of his under standing of crystal structures and his role as passionate skeptic have frequently been invaluable. Professor John Cowley has also been an invaluable sounding board for ideas, and was responsible for much of the experimental and theoretical work on coherent nanodiffraction. The sections on this topic derive mainly from collaborations by J. C. H. S. with him in the seventies."
The Nobel Prize of 1986 on Sc- ningTunnelingMicroscopysignaled a new era in imaging. The sc- ning probes emerged as a new - strument for imaging with a p- cision suf?cient to delineate single atoms. At ?rst there were two - the Scanning Tunneling Microscope, or STM, and the Atomic Force Mic- scope, or AFM. The STM relies on electrons tunneling between tip and sample whereas the AFM depends on the force acting on the tip when it was placed near the sample. These were quickly followed by the M- netic Force Microscope, MFM, and the Electrostatic Force Microscope, EFM. The MFM will image a single magnetic bit with features as small as 10nm. With the EFM one can monitor the charge of a single electron. Prof. Paul Hansma at Santa Barbara opened the door even wider when he was able to image biological objects in aqueous environments. At this point the sluice gates were opened and a multitude of different instruments appeared. There are signi?cant differences between the Scanning Probe Microscopes or SPM, and others such as the Scanning Electron Microscope or SEM. The probe microscopes do not require preparation of the sample and they operate in ambient atmosphere, whereas, the SEM must operate in a vacuum environment and the sample must be cross-sectioned to expose the proper surface. However, the SEM can record 3D image and movies, features that are not available with the scanning probes.
vi on geometric probability is included, students can be expected to create a few simple programs like those shown, but for other geometries. I am indebted to Tom Hare for critical reviews of the material and an endless enthusiasm to debate and derive stereological relationships; to John Matzka at Plenum Press for patiently instructing me in the intricacies of typesetting; to Chris Russ for helping to program many of these measurement techniques; and especially to Helen Adams, both for her patience with my creative fever to write yet another book, and for pointing out that the title, which I had intended to contrast to "theoretical stereology," can also be understood as the antonym of "impractical stereology."

This easy-to-follow manual describes tested procedures used to prepare biological samples for scanning and transmission electron microscopy, as well as methods for cytochemistry, immunocytochemistry, and scientific photography. The work is structured to clearly define testing objectives, necessary materials, procedural steps, and expected results; a list of references and trouble shooting techniques round out the text.
The International Conference on Laser Physics and Quantum Optics was held in Shanghai from August 25 to August 28, 1999, to discuss many exciting new developments in laser physics and quantum optics. The international character of the conference was manifested by the fact that scientists from over 13 countries participated and lectured at the conference. There were four keynote lectures delivered by Nobel laureate Willis Lamb, Jr., Profs. H. Walther, A.E. Siegman and M.O. Scully. In addition, there were 34 invited lectures, 27 contributed oral presentations, and 59 poster papers. This volume contains many of the papers presented at the conference.
Polymer Microscopy, 3rd Edition, is a comprehensive and practical guide to the study of the microstructure of polymers, and is the result of the authors' many years of academic and industrial experience. To address the needs of students and professionals from a variety of backgrounds, introductory chapters deal with the basic concepts of both polymer morphology and processing and microscopy and imaging theory. The core of the book is more applied, with many examples of specimen preparation and image interpretation leading to materials characterization.Microscopy is applied to the characterization of a wide range of polymer systems, including fibers, films, engineering resins and plastics, composites, nanocomposites, polymer blends, emulsions and liquid crystaline polymers. Light microscopy, atomic force microscopy, scanning and transmission electron microscopy techniques are all considered, as are emerging techniques such as compositional mapping in which microscopy is combined with spectroscopy. This extensively updated and revised third edition closes with a problem solving guide, which gives a systematic framework for deciding on suitable approaches to the characterization of
The 2nd International Multidisciplinary Microscopy and Microanalysis Congress & Exhibition (InterM 2014) was held on 16-19 October 2014 in Oludeniz, Fethiye/ Mugla, Turkey. The aim of the congress was to gather scientists from various branches and discuss the latest improvements in the field of microscopy. The focus of the congress has been widened in an "interdisciplinary" manner, so as to allow all scientists working on several related subjects to participate and present their work. These proceedings include 33 peer-reviewed technical papers, submitted by leading academic and research institutions from over 17 countries and representing some of the most cutting-edge research available. The papers were presented at the congress in the following sessions: * Applications of Microscopy in the Physical Sciences * Applications of Microscopy in the Biological Sciences
Three-dimensional x-ray diffraction (3DXRD) microscopy is a novel experimental method for structural characterisation of polycrystalline materials. The position, morphology, phase, strain and crystallographic orientation of hundreds of grains or sub-grain embedded within mm-cm thick specimens can be determined simultaneously. Furthermore, the dynamics of the individual structural elements can be monitored during typical processes such as deformation or annealing. The book gives a comprehensive account of the methodology followed by a summary of selected applications. The method is presented from a mathematical/crystallographic point-of-view but with sufficient hands-on details to enable the reader to plan his or her own experiments. The scope of applications includes work in materials science and engineering, geophysics, geology, chemistry and pharmaceutical science.
Since its discovery, Atomic Force Microscopy (AFM) has become a technique of choice for non-destructive surface characterization with sub-molecular resolution. The AFM has also emerged as a problem-solving tool in applications relevant to particle-solid and particle-liquid interactions, design, fabrication, and characterization of new materials, and development of new technologies for processing and modification of materials. This volume is a comprehensive review of AFM techniques and their application in adhesion studies. It is intended for both researchers and students in engineering disciplines, physics and biology. Over 100 authors contributed to this book, summarizing current status of research on measurements of colloidal particle-solid adhesion and molecular forces, solid surface imaging and mapping, and discussing the contact mechanics models applicable to particle-substrate and particle-particle systems.
Since the pioneering discoveries of Hodgkin, Huxley, and Katz, it has been clear that specific ion conductance pathways underlie electrical act- ity. Over the ensuing 50 years, there has been ever increasing, and occasi- ally explosive, changes in the scope of efforts to understand ion channel behavior. The introduction of patch clamp technology by Erwin Neher and Bert Sakmann about 20 years ago led to the realization of the great variety of novel ion channel species, and the subsequent revolution in cl- ing has revealed an even greater diversity of the underlying molecular entities. Today, advances in the study of ion channel structure and function c- tinue at a high pace, from angstrom resolution imaging of crystallized ch- nels to their genetic manipulations in animals. In this regard, the field is a balanced one that inquires not only what ion channel entities are there, or how they operate, but also where are these molecular electronic switches? However, this balance is not particularly well presented to the general sci- tific audience or to specialists in the field. There are plenty of wonderful and useful books and monographs, as well as conferences and meetings on v- tually every aspect of ion channel structure and function. However, we are unaware that the channel localization theme has been considered in a u- fied forum.
This volume examines the physical and technical foundation for recent progress in applied near-field scanning probe techniques. It constitutes a timely comprehensive overview of SPM applications, now that industrial applications span topographic and dynamical surface studies of thin-film semiconductors, polymers, paper, ceramics, and magnetic and biological materials. After laying the theoretical background of static and dynamic force microscopies, including sensor technology and tip characterization, contributions detail applications such as macro- and nanotribology, polymer surfaces, and roughness investigations. The final part on industrial research addresses special applications of scanning force nanoprobes such as atomic manipulation and surface modification, as well as single electron devices based on SPM. Scientists and engineers either using or planning to use SPM techniques will benefit from the international perspective assembled in the book.
This is a book about fishermen's reasons for obeying fisheries law. The fish harvesting industry has become subject to state interference to an increasing extent over the past twenty years. As natural resources become scarce and subsequent fisheries regulations abound, the question of law-abidingness is brought to the public agenda. However, there is still little empirical data as regards the dynamics of compliance in this field, and this book aims to meet a demand for in-depth knowledge. The cases studied can be regarded as instances of economies dependent on the harvesting of natural resources for both household and the market, and the study aims to contribute to the building of more adequate theory on the dynamics of compliance in such economies. However, focusing on a specific type of setting seldom constitutes a safe escape route for getting away from more pervasive sociological questions, and it certainly does not in this case. As any attempt to explain social phenomena, this study is faced with the fundamental sociological question of how the acts of individuals can best be understood. The question concerns the interface between the individual and the collectivity - between collective morality and self-interest. It thus deals with classical sociological issues such as the nature and regulatory capacity of group norms and sanctions, and the forms and roles of rationality and strategic action.
Despite their importance in terms of employment and income generation, inshore fisheries have been a neglected area of study. The review of the common fisheries policy, especially in the light of the need to re-examine the derogation which reserves access to the inshore zone to coastal state vessels, provides an opportunity to redress the balance. With contributions from leading authorities on fisheries management, the book takes an in-depth look at seven European countries, examining the basis for the definition of inshore fisheries, evaluating their status, and describing the salient characteristics of their management. The national studies form the basis for cross-cultural analyses of the social organisation, cultural norms, economic objectives, and institutional structures of inshore fisheries in Europe. Finally, a number of key issues relating to the future of inshore fisheries management in a more integrated approach are examined. Overall the volume reaffirms the invaluable role played by inshore fisheries in the local and regional economies of Europe's complex coastline.
Experienced and novice holographers receive a solid foundation in the theory and practice of holography, the next generation of imaging technology, in this superb text. The book's 'how to' aspects enable readers to learn hologram acquisition at the microscope and processing of holograms at the computer as well as digital imaging techniques. A complete bibliography on electron holography and applications of the method to problems in materials science, physics and the life sciences round out the volume's coverage.
The main objective of this book is to systematically describe the basic principles of the most widely used techniques for the analysis of physical, structural, and compositional properties of solids with a spatial resolution of approxi mately 1 m or less. Many books and reviews on a wide variety of microanalysis techniques have appeared in recent years, and the purpose of this book is not to replace them. Rather, the motivation for combining the descriptions of various mi croanalysis techniques in one comprehensive volume is the need for a reference source to help identify microanalysis techniques, and their capabilities, for obtaining particular information on solid-state materials. In principle, there are several possible ways to group the various micro analysis techniques. They can be distinguished by the means of excitation, or the emitted species, or whether they are surface or bulk-sensitive techniques, or on the basis of the information obtained. We have chosen to group them according to the means of excitation. Thus, the major parts of the book are: Electron Beam Techniques, Ion Beam Techniques, Photon Beam Techniques, Acoustic Wave Excitation, and Tunneling of Electrons and Scanning Probe Microscopies. We hope that this book will be useful to students (final year undergrad uates and graduates) and researchers, such as physicists, material scientists, electrical engineers, and chemists, working in a wide variety of fields in solid state sciences."
More than half of the world's petroleum is to be found in carbonate rocks, for example in the Middle East, the former USSR and in North America. These rocks show a bewildering diversity of grains and textures, due in part to the wealth of different fossil organisms which have contributed to carbonate sedimentation, and in part to a wide variety of diagenetic processes which can radically modify textures and obscure the depositional fabric. Careful petrographic study with a polarising microscope is a key element of any study of carbonate sediments, as a companion to field or core logging, and as a necessary precursor to geochemical analysis. This atlas, which illustrates in full colour a range of features not attempted in any general textbook, is designed as a laboratory manual to keep beside the microscope, as an aid to identifying grain types and textures in carbonates. It appeals alike to undergraduate and graduate students and to professionals in teaching institutions, research laboratories and industry.
The first volume in the series was released in January 2004 and the second to fourth volumes in early 2006.

This research-level reference provides a review of the morphological techniques that have become a primary method of anatomical study correlating structure and function in lung physiology and pathology. Detailing the evolution of anatomy as a research discipline, it explores general structural techn
This book presents comprehensive studies of charge density waves (CDW) in a high-Tc cuprate superconductor using x-ray scattering techniques under uniaxial pressure. Specifically, the work addresses inelastic x-ray scattering studies under uniaxial pressure performed on the underdoped cuprate YBa2Cu3O6.67(p=0.12, Tc=65K) with incoming photon energy in the resonant (E=931.3 eV, Cu-L3 edge) and non-resonant conditions (E=17.794 keV). This is a completely new approach to the investigation of charge density waves. It revealed new features of charge density waves in cuprates, whose properties had previously been inaccessible..
This volume contains invited and contributed papers presented at the conference on 'Microscopy of Semiconducting Materials' held at the University of Cambridge on 2-5 April 2007. The event was organised under the auspices of the Electron Microscopy and Analysis Group of the Institute of Physics, the Royal Microscopical Society and the Materials Research Society. This international conference was the fifteenth in the series that focuses on the most recent world-wide advances in semiconductor studies carried out by all forms of microscopy and it attracted delegates from more than 20 countries. With the relentless evolution of advanced electronic devices into ever smaller nanoscale structures, the problem relating to the means by which device features can be visualised on this scale becomes more acute. This applies not only to the imaging of the general form of layers that may be present but also to the determination of composition and doping variations that are employed. In view of this scenario, the vital importance of transmission and scanning electron microscopy, together with X-ray and scanning probe approaches can immediately be seen. The conference featured developments in high resolution microscopy and nanoanalysis, including the exploitation of recently introduced aberration-corrected electron microscopes. All associated imaging and analytical techniques were demonstrated in studies including those of self-organised and quantum domain structures. Many analytical techniques based upon scanning probe microscopies were also much in evidence, together with more general applications of X-ray diffraction methods.
The April 1997 conference held in Prague attracted the cream of primarily European and Russian researchers (with a handful from the US, primarily from the U. of Maryland School of Medicine) to the burgeoning biological and medical applications of innovative optical technology, particularly laser con |
