Atom-probe field ion microscopy is currently the only technique capable of imaging solid surfaces with atomic resolution, and at the same time of chemically analysing surface atoms selected by the observer from the field ion image. Field ion microscopy has been successfully used to study most metals and many alloys, and recently good field ion images of some semiconductors and even ceramic materials such as high temperature superconductors have been obtained. Although other microscopies are capable of achieving the same resolution, there are some experiments unique to field ion microscopy - for example the study of the behaviour of single atoms and clusters on a solid surface. The elegant development of the field ion microscope with the atom probe has provided a powerful and useful technique for highly sensitive chemical analysis. This book presents the basic principles of atom-probe field ion microscopy and illustrates the various capabilities of the technique in the study of solid surfaces and interfaces at atomic resolution. A useful comparison is given with two related techniques, electron microscopy and scanning tunnelling microscopy. The book will be of interest to scientists working on surfaces and interfaces of materials at the atomic level and will provide a useful reference for those using this technique.
Now fully updated to cover recent developments, this book covers the closely related techniques of electron microprobe analysis (EMPA) and scanning electron microscopy (SEM) specifically from a geological viewpoint. Topics discussed include: principles of electron-target interactions, electron beam instrumentation, X-ray spectrometry, general principles of SEM image formation, production of X-ray 'maps' showing elemental distributions, procedures for qualitative and quantitative X-ray analysis (both energy-dispersive and wavelength-dispersive), the use of both 'true' electron microprobes and SEMs fitted with X-ray spectrometers, and practical matters such as sample preparation and treatment of results. Throughout, there is an emphasis on geological aspects not mentioned in similar books aimed at a more general readership. The book avoids unnecessary technical detail in order to be easily accessible, and forms an up-to-date text on EMPA and SEM for geological postgraduate and postdoctoral researchers, as well as those working in industrial laboratories.

The scanning tunnelling microscope (STM) was invented by Binnig and Rohrer and received a Nobel Prize of Physics in 1986. Together with the atomic force microscope (AFM), it provides non-destructive atomic and subatomic resolution on surfaces. Especially, in recent years, internal details of atomic and molecular wavefunctions are observed and mapped with negligible disturbance. Since the publication of its first edition, this book has been the standard reference book and a graduate-level textbook educating several generations of nano-scientists. In Aug. 1992, the co-inventor of STM, Nobelist Heinrich Rohrer recommended: "The Introduction to Scanning tunnelling Microscopy by C.J. Chen provides a good introduction to the field for newcomers and it also contains valuable material and hints for the experts". For the second edition, a 2017 book review published in the Journal of Applied Crystallography said "Introduction to Scanning tunnelling Microscopy is an excellent book that can serve as a standard introduction for everyone that starts working with scanning probe microscopes, and a useful reference book for those more advanced in the field". The third edition is a thoroughly updated and improved version of the recognized "Bible" of the field. Additions to the third edition include: theory, method, results, and interpretations of the non-destructive observation and mapping of atomic and molecular wavefunctions; elementary theory and new verifications of equivalence of chemical bond interaction and tunnelling; scanning tunnelling spectroscopy of high Tc superconductors; imaging of self-assembled organic molecules on the solid-liquid interfaces. Some key derivations are rewritten using mathematics at an undergraduate level to make it pedagogically sound.
This book highlights the first systematic synthesis of various research approaches in forensic medical diagnosis of the morphological and polycrystalline structure of human biological tissues and biological fluids. One of the global challenges in such diagnosis is the assessment of actual time of death. The relevance and objectivity of such studies are given by the innovative use of complex multifunctional methods using lasers and Mueller-matrix polarimetry, which is presented in this book. As a result, within the framework of the statistical, correlation and fractal approaches, diagnostic relationships were established between the time parameters of the transformation of the topographic structure of polarization-inhomogeneous microscopic images of biological preparations and necrotic changes in the morphological structure of biological tissues of the deceased. On this foundation, new forensic medicine criteria have been developed for objective determination of time of death.
This completely revised new edition contains expanded coverage of existing topics and much new material. The author presents the subject of electron microscopy in a readable way, open both to those inexperienced in the technique, and also to practicing electron microscopists. He describes currently hot topics such as computer control of microscopes, energy-filtered imaging, cryomicroscopy and environmental microscopy, digital imaging, high resolution scanning, and transmission microscopy. The author has expanded the highly praised case studies of the first edition to include some interesting new examples. This indispensable guide to electron microscopy, written by an author with thirty years' practical experience, will be invaluable to new and experienced electron microscopists in any area of science and technology.
The investigation and manipulation of matter on the atomic scale have been revolutionized by scanning tunneling microscopy and related scanning probe techniques. This book is the first to provide a clear and comprehensive introduction to this subject. Beginning with the theoretical background of scanning tunneling microscopy, the design and instrumentation of practical STM and associated systems are described in detail, including topographic imaging, local tunneling barrier height measurements, tunneling spectroscopy, and local potentiometry. A treatment of the experimental techniques used in scanning force microscopy and other scanning probe techniques rounds out this section. The second part discusses representative applications of these techniques in fields such as condensed matter physics, chemistry, materials science, biology, and nanotechnology, so this book will be extremely valuable to upper-division students and researchers in these areas.
Microscopy, which has served as a fundamental scientific technique for centuries, remains an invaluable tool in chemistry, biology, healthcare, and forensics. Increasingly, it is being integrated into modern chemical instrumentation and is of value as a powerful analytical tool across many scientific disciplines. Designed to serve as a primary resource for undergraduate or graduate students, An Introduction to Microscopy helps students master the foundational principles of microscopy. Intentionally concise, this text does not attempt to cover all aspects of all types of microscopy such as polarizing light and fluorescence. Instead, the authors' intent is to provide students with the basic knowledge necessary to explore and understand these more advanced techniques. The authors draw from their own extensive backgrounds in forensic identification to explain the methods and ways in which microscopy shapes every investigation. All nine chapters include questions and most include simple exercises related to the material covered. Numerous figures and photographs supplement the text and explain the procedures and principles introduced. A glossary is included as well as a convenient list of abbreviations, and references to more in-depth readings. Offers a Fundamental Approach for Students in all Fields The material assumes basic mathematics skill through algebra and a basic knowledge of fundamental chemistry and physics (essential for understanding optics). Although the authors used the high-quality microscopes found in their laboratories to produce the images found in the book, the information and methods can be applied to any type of microscope to which students have access. Understanding the fundamentals of microscopy provides students with a relevant and marketable skill that can be readily applied in many fields, even if the students have not had significant academic training in the subject. Furthermore, by understanding various aspects of microscopy, students will begin to understand the science behind other related areas, such as spectroscopy, optics, and any number of applications involving analytical instrumentation.
This book explains the operating principles of atomic force microscopy with the aim of enabling the reader to operate a scanning probe microscope successfully and understand the data obtained with the microscope. This enhanced second edition to "Scanning Probe Microscopy" (Springer, 2015) represents a substantial extension and revision to the part on atomic force microscopy of the previous book. Covering both fundamental and important technical aspects of atomic force microscopy, this book concentrates on the principles the methods using a didactic approach in an easily digestible manner. While primarily aimed at graduate students in physics, materials science, chemistry, nanoscience and engineering, this book is also useful for professionals and newcomers in the field, and is an ideal reference book in any atomic force microscopy lab.
This is an extensively illustrated laboratory manual of transmission electron microscopy techniques for the technician, graduate student, or researcher. Chapters begin with a general discussion, move on to the chemicals and equipment required for the method being described and conclude with a step-by-step presentation of the method and instructions for the preparation of solutions. Notes at the end of each chapter warn of possible pitfalls and outline 'tricks of the trade'. The methods and techniques outlined have been tested for over ten years in clinical and research laboratory situations, and are entirely reliable. Practical Electron Microscopy covers fixation, dehydration and embedding, semi-thin and thin sectioning, the electron microscope, and photography. For this new edition, the chapters on photography and the electron microscope have been completely rewritten and two new chapters have been added, one on immuno electron microscopy using colloidal gold, and one dealing with such special techniques as retrieving specimens from paraffin and handling nasal brushings and blood samples. This manual will be an invaluable guide to anyone using electron microscopy on human and animal tissue and wishing to develop a routine that guarantees good and reproducible results.
The compound optical microscope, in its various modern forms, is probably the most familiar of all laboratory instruments and the electron microscope, once an exotic rarity, has now become a standard tool in biological and materials research. Both instruments are often used effectively with little knowledge of the relevant theory, or even of how a particular type of microscope functions. Eventually however, proper use, interpretation of images and choices of specific applications demand an understanding of fundamental principles. This book describes the principles of operation of each type of microscope currently available and of use to biomedical and materials scientists. It explains the mechanisms of image formation, contrast and its enhancement, accounts for ultimate limits on the size of observable details (resolving power and resolution) and finally provides an account of Fourier optical theory. Principles behind the photographic methods used in microscopy are also described and there is some discussion of image processing methods. The book will appeal to graduate students and researchers in the biomedical sciences, and it will be helpful to students taking a course involving the principles of microscopy.
This technology has proved indispensable as a characterization tool with applications in surface physics, chemistry, materials science, bio-science, and data storage media. It has also shown great potential in areas such as the semiconductor and optical quality control industries. This revised edition updates the earlier such survey of the many rapidly developing subjects concerning the mapping of a variety of forces across surfaces, including basic theory, instrumentation, and applications. It also includes important new research in SFM and a thoroughly revised bibliography. Academic and industrial researchers using SFM or wishing to know more about its potential, will find this book an excellent introduction to this rapidly developing field.
The first book on the topic, with each chapter written by pioneers in the field, this essential resource details the fundamental theory, applications, and future developments of liquid cell electron microscopy. This book describes the techniques that have been developed to image liquids in both transmission and scanning electron microscopes, including general strategies for examining liquids, closed and open cell electron microscopy, experimental design, resolution, and electron beam effects. A wealth of practical guidance is provided, and applications are described in areas such as electrochemistry, corrosion and batteries, nanocrystal growth, biomineralization, biomaterials and biological processes, beam-induced processing, and fluid physics. The book also looks ahead to the future development of the technique, discussing technical advances that will enable higher resolution, analytical microscopy, and even holography of liquid samples. This is essential reading for researchers and practitioners alike.
Basic Confocal Microscopy, Second Edition builds on the successful first edition by keeping the same format and reflecting relevant changes and recent developments in this still-burgeoning field. This format is based on the Confocal Microscopy Workshop that has been taught by several of the authors for nearly 20 years and remains a popular workshop for gaining basic skills in confocal microscopy. While much of the information concerning fluorescence and confocal microscopy that made the first edition a success has not changed in the six years since the book was first published, confocal imaging is an evolving field and recent advances in detector technology, operating software, tissue preparation and clearing, image analysis, and more have been updated to reflect this. Several of these advances are now considered routine in many laboratories, and others such as super resolution techniques built on confocal technology are becoming widely available.
This is a practical book for health and IT professionals who need to ensure that patient safety is prioritized in the design and implementation of clinical information technology. Healthcare professionals are increasingly reliant on information technology to deliver care and inform their clinical decision making. Health IT provides enormous benefits in efficiency, communication and decision making. However a number of high-profile UK and US studies have concluded that when Health IT is poorly designed or sub-optimally implemented then patient safety can be compromised. Manufacturers and healthcare organizations are increasingly required to demonstrate that their Health IT solutions are proactively assured. Surprisingly the majority of systems are not subject to regulation so there is little in the way of practical guidance as to how risk management can be achieved. The book fills that gap. The author, a doctor and IT professional, harnesses his two decades of experience to characterize the hazards that health technology can introduce. Risk can never be eliminated but by drawing on lessons from other safety-critical industries the book systematically sets out how clinical risk can be strategically controlled. The book proposes the employment of a Safety Case to articulate and justify residual risk so that not only is risk proactively managed but it is seen to be managed. These simple techniques drive product quality and allow a technology's benefits to be realized without compromising patient safety.
This book showcases new and innovative approaches to biometric data capture and analysis, focusing especially on those that are characterized by non-intrusiveness, reliable prediction algorithms, and high user acceptance. It comprises the peer-reviewed papers from the international workshop on the subject that was held in Ancona, Italy, in October 2014 and featured sessions on ICT for health care, biometric data in automotive and home applications, embedded systems for biometric data analysis, biometric data analysis: EMG and ECG, and ICT for gait analysis. The background to the book is the challenge posed by the prevention and treatment of common, widespread chronic diseases in modern, aging societies. Capture of biometric data is a cornerstone for any analysis and treatment strategy. The latest advances in sensor technology allow accurate data measurement in a non-intrusive way, and in many cases it is necessary to provide online monitoring and real-time data capturing to support a patient's prevention plans or to allow medical professionals to access the patient's current status. This book will be of value to all with an interest in this expanding field.
Scanning electr on microscopy (SEM) and x-ray microanalysis can produce magnified images and in situ chemical information from virtually any type of specimen. The two instruments generally operate in a high vacuum and a very dry environment in order to produce the high energy beam of electrons needed for imaging and analysis. With a few notable exceptions, most specimens destined for study in the SEM are poor conductors and composed of beam sensitive light elements containing variable amounts of water. In the SEM, the imaging system depends on the specimen being sufficiently electrically conductive to ensure that the bulk of the incoming electrons go to ground. The formation of the image depends on collecting the different signals that are scattered as a consequence of the high energy beam interacting with the sample. Backscattered electrons and secondary electrons are generated within the primary beam-sample interactive volume and are the two principal signals used to form images. The backscattered electron coefficient ( ? ) increases with increasing atomic number of the specimen, whereas the secondary electron coefficient ( ? ) is relatively insensitive to atomic number. This fundamental diff- ence in the two signals can have an important effect on the way samples may need to be prepared. The analytical system depends on collecting the x-ray photons that are generated within the sample as a consequence of interaction with the same high energy beam of primary electrons used to produce images.
