Book Description
Structural phase transitions, mechanical deformations, and the embryonic stages of melting and crystallization are examples of phenomena that can now be imaged in unprecedented structural detail with high spatial resolution, and ten orders of magnitude as fast as hitherto. No monograph in existence attempts to cover the revolutionary dimensions that EM in its various modes of operation nowadays makes possible. The authors of this book chart these developments, and also compare the merits of coherent electron waves with those of synchrotron radiation. They judge it prudent to recall some important basic procedural and theoretical aspects of imaging and diffraction so that the reader may better comprehend the significance of the new vistas and applications now afoot. This book is not a vade mecum - numerous other texts are available for the practitioner for that purpose.

Book Description
The modern electron microscope, as a result of recent revolutionary developments and many evolutionary ones, now yields a wealth of quantitative knowledge pertaining to structure, dynamics, and function barely matched by any other single scientific instrument. It is also poised to contribute much new spatially-resolved and time-resolved insights of central importance in the exploration of most aspects of condensed matter, ranging from the physical to the biological sciences. Whereas in all conventional EM methods, imaging, diffraction, and chemical analyses have been conducted in a static — time-integrated — manner, now it has become possible to unite the time domain with the spatial one, thereby creating four-dimensional (4D) electron microscopy. This advance is based on the fundamental concept of timed, coherent single-electron packets, or electron pulses, which are liberated with femtosecond durations. Structural phase transitions, mechanical deformations, and the embryonic stages of melting and crystallization are examples of phenomena that can now be imaged in unprecedented structural detail with high spatial resolution, and ten orders of magnitude as fast as hitherto. No monograph in existence attempts to cover the revolutionary dimensions that EM in its various modes of operation nowadays makes possible. The authors of this book chart these developments, and also compare the merits of coherent electron waves with those of synchrotron radiation. They judge it prudent to recall some important basic procedural and theoretical aspects of imaging and diffraction so that the reader may better comprehend the significance of the new vistas and applications now afoot. This book is not a vade mecum — numerous other texts are available for the practitioner for that purpose. It is instead an in-depth exposé of the paradigm concepts and the developed techniques that can now be executed to gain new knowledge in the entire domain of biological and physical science, and in the four dimensions of space and time.

A book to make the experts think.”Professor John Spence Arizona State University, USA “This is one of the most enlightening science textbooks I have ever read. The basic concepts behind 3D and 4D electron microscopy are presented in a concise and clear language, accompanied by figures of remarkable didactic content. This excellent textbook blends the qualities of an introductory with an in-depth account, and is bound to become a reference in the field.”Professor Majed Chergui EPFL, Lausanne, Switzerland “This is a fascinating book, very timely published when electron microscopy (EM) is at a turning point with dramatically improved capacities … The description of scattering of electrons and the function of the electron microscope is sufficiently complete to make this book well suited as a university textbook.”Crystallography Reviews “Combining the authors' expertise in femtochemistry, catalysis, and electron microscopy has resulted in a book that conveys the excitement and potential for this new paradigm in electron imaging … there is no doubt that the development of the 4D microscope has introduced a new paradigm for characterization by TEM. Taken together with introductory texts covering TEM, it provides the understanding necessary for the reader to appreciate the principles of this brand new field.”Journal of the American Chemistry Society “Researchers using electron microscopy will find this book fascinating and very helpful for learning about the latest advances in electron microscopy imaging technology.”IEEE Electrical Insulation Magazine “The renowned authors of this new appearance on time-resolved 3D electron microscopy have created a fantastic book that will appeal to a broad range of scientists. Its topic and breadth will surely be of interest to those interested in physics, material science, and solid-state chemistry … The expertise of the authors and the clear, well-documented nature of the book combine to lend it great potential to set the standard in this field.”Angewandte Chemie “It is for the 'ultrafast' chapters that the book will be read for these contain new and very unfamiliar material. The book is handsomely produced with all the illustrations on a Cambridge blue background.”Ultramicroscopy “The expert reader, who believes to know every aspect regarding electron microscopy, will discover many new and inspiring elements. For the electron microscopy layman it will ignite a fire for this exciting, trans-disciplinary subject area.”Prof. Dr. Armin Feldhoff Leibniz University Hannover

Book Description
Ever since the beginning of mankind's efforts to pursue scientific inquiry into the laws of nature, visualization of the very distant and the very small has been paramount. The examples are numerous. A century ago, the atom appeared mysterious, a “raisin or plum pie of no structure,” until it was visualized on the appropriate length and time scales. Similarly, with telescopic observations, a central dogma of the cosmos was changed and complexity yielded to simplicity of the heliocentric structure and motion in our solar system. For matter, in over a century of developments, major advances have been made to explore the inner microscopic structures and dynamics. These advances have benefited many fields of endeavor, but visualization was incomplete; it was limited either to the 3D spatial structure or to the 1D temporal evolution. However, in systems with myriads of atoms, 4D spatiotemporal visualization is essential for dissecting their complexity. The biological world is rich with examples, and many molecular diseases cannot be fully understood without such direct visualization, as, for example, in the case of Alzheimer's and Parkinson's. The same is true for phenomena in materials science, chemistry, and nanoscience. This anthology is an account of the collected works that have emerged over the past decade from Caltech. Through recent publications, the volume provides overviews of the principles, the electron-based techniques, and the applications made. Thanks to advances in imaging principles and technology, it is now possible with 4D electron microscopy to reach ten orders of magnitude improvement in time resolution while simultaneously conserving the atomic spatial resolution in visualization. This is certainly a long way from Robert Hooke's microscopy, which was recorded in his 1665 masterpiece Micrographia.

Book Description
TEM and SEM have contributed greatly to the progress of various research fields, which has been accelerated in the last few decades by highly functional electron microscopes and microscopy. In this tide of microscopy, various microscopic methods have been developed to make clear many unsolved problems, e.g. pulse beam TEM, environmental microscopy, correlative microscopy, etc. In this book, a number of reviews have been collected concerning these subjects. We think that the content in each chapter is impressive, and we hope this book will contribute to future advances in electron microscopy, materials science, and biomedicine.

Book Description
This text is a companion volume to Transmission Electron Microscopy: A Textbook for Materials Science by Williams and Carter. The aim is to extend the discussion of certain topics that are either rapidly changing at this time or that would benefit from more detailed discussion than space allowed in the primary text. World-renowned researchers have contributed chapters in their area of expertise, and the editors have carefully prepared these chapters to provide a uniform tone and treatment for this exciting material. The book features an unparalleled collection of color figures showcasing the quality and variety of chemical data that can be obtained from today’s instruments, as well as key pitfalls to avoid. As with the previous TEM text, each chapter contains two sets of questions, one for self assessment and a second more suitable for homework assignments. Throughout the book, the style follows that of Williams & Carter even when the subject matter becomes challenging—the aim is always to make the topic understandable by first-year graduate students and others who are working in the field of Materials Science Topics covered include sources, in-situ experiments, electron diffraction, Digital Micrograph, waves and holography, focal-series reconstruction and direct methods, STEM and tomography, energy-filtered TEM (EFTEM) imaging, and spectrum imaging. The range and depth of material makes this companion volume essential reading for the budding microscopist and a key reference for practicing researchers using these and related techniques.
