X-Planes: German Luftwaffe Prototypes 1930-1945
In this superb illustrated guide, renowned German aviation specialist Manfred Griehl has collected a unique and valuable selection of photographs of Luftwaffe projects that never made it into battle. They remained on the drawing board or at prototype stage either because they were deemed unsuitable or the developers simply ran out of time and the projects never went into production. There are examples of Fw190s developed for the delivery of chemical and toxic weapons, the high altitude Junkers EF 61, the early prototype WNF 342 helicopter as well as numerous examples of developmental jet fighters that could very well have been realised had it not been for the effectiveness of the Allied bombing campaign in restricting the supply of necessary materials. Much of this development work went on to have an important influence on aircraft design in both the East and the West after the Second World War, making this book an essential source not just for those interested in Hitler's Luftwaffe but also in the history of military aviation in general.

The ultra-bright femtosecond X-ray pulses provided by X-ray free electron lasers (XFELs) open up opportunities to study the structure and dynamics of a wide variety of systems beyond what is possible with synchrotron sources. This book introduces the principles and properties of currently operating and future XFELs, before outlining applications in materials science, chemistry and biology. Edited by pioneers in this exciting field, and featuring contributions from leading researchers, this book is ideal for researchers working with XFELs, synchrotron radiation, ultrafast and femtosecond crystallography and femtosecond spectroscopy.
X-ray Scattering From Semiconductors (2nd Edition)

X-ray Scattering From Semiconductors (2nd Edition)

Paul F Fewster

Imperial College Press
2003
sidottu
This book presents a practical guide to the analysis of materials and includes a thorough description of the underlying theories and instrumental aberrations caused by real experiments. The main emphasis concerns the analysis of thin films and multilayers, primarily semiconductors, although the techniques are very general. Semiconductors can be very perfect composite crystals and therefore their study can lead to the largest volume of information, since X-ray scattering can assess the deviation from perfection.The description is intentionally conceptual so that the reader can grasp the real processes involved. In this way the analysis becomes significantly easier, making the reader aware of misleading artifacts and assisting in the determination of a more complete and reliable analysis. The theory of scattering is very important and is covered in such a way that the assumptions are clear. Greatest emphasis is placed on the dynamical diffraction theory including new developments extending its applicability to reciprocal space mapping and modelling samples with relaxed and distorted interfaces.A practical guide to the measurement of diffraction patterns, including the smearing effects introduced to the measurement, is also presented.

This title features 19 projects that are designed to appeal to both male and female stitchers, from UK author Sarah Fordham. It offers a cool and contemporary take on cross-stitching. This is a contemporary cross-stitch design and project book - a refreshing and modern take on the traditional craft of cross-stitching that will appeal to an audience that keeps up with current trends. The reader will be guided through the materials and tools of the trade before being taught the fundamental techniques of cross-stitching. The projects are divided into three sections: Simple, Trickier and Challenging. The projects are wide-ranging, from buttons, hair bobbles and brooches, to watch straps, coasters, tote bags, customized pumps and Peter Pan collars. Readers can experiment with working up miniature designs to large-scale canvases and rugs. Finally, there is a chapter on Thinking Outside the Box, with suggestions of alternative materials and ideas to explore.

X-Ray Crystallography is a well-balanced, thorough, and clearly written introduction to the most important and widely practiced technique to determine the arrangement of atoms in molecules and solids. Featuring excellent illustrations and homework problems throughout, the book is intended both for advanced undergraduate and graduate students who are learning the subject for the first time, as well as for those who have practical experience but seek a text summarizing the theory of diffraction and X-ray crystallography. It is organized into three parts: Part 1 deals with symmetry and space groups, Part 2 explains the physics of X rays and diffraction, and Part 3 examines the methods for solving and refining crystal structures. The discussion proceeds in a logical and clear fashion from the fundamentals through to advanced topics such as disorder, twinning, microfocus sources, low energy electron diffraction, charge flipping, protein crystallography, the maximum likelihood method of refinement, and powder, neutron, and electron diffraction. The author’s clear writing style and distinctive approach is well suited for chemists, biologists, materials scientists, physicists, and scientists from related disciplines. A detailed Instructor's Manual is available for adopting professors.
X-Ray Diffraction by Polycrystalline Materials
This book presents a physical approach to the diffraction phenomenon and its applications in materials science. An historical background to the discovery of X-ray diffraction is first outlined. Next, Part 1 gives a description of the physical phenomenon of X-ray diffraction on perfect and imperfect crystals. Part 2 then provides a detailed analysis of the instruments used for the characterization of powdered materials or thin films. The description of the processing of measured signals and their results is also covered, as are recent developments relating to quantitative microstructural analysis of powders or epitaxial thin films on the basis of X-ray diffraction. Given the comprehensive coverage offered by this title, anyone involved in the field of X-ray diffraction and its applications will find this of great use.

X-ray Phase Contrast Imaging

X-ray Phase Contrast Imaging

This book fills an important gap in the existing literature by providing a comprehensive discussion of X-ray Phase Contrast Imaging (XPCi) and its various uses and implementations. XPCi could revolutionise all applications of X-ray imaging. It exploits a different mechanism to generate image contrast (refraction/interference instead of absorption), thus enhancing the visibility of all details, allowing the detection of features that are classically considered invisible.XPCi emerged in the mid-1990s, primarily at synchrotron radiation facilities. Initially, its use was considered to be very restricted due to the stringent requirements imposed on the radiation source. New methods which allow XPCi to be used with conventional X-ray sources have recently emerged, thus providing concrete possibilities for transfer into mainstream applications. This has renewed enthusiasm in the field and spawned a large number of new research groups worldwide.This book follows a historical perspective and describes all possible implementations of XPCi. In each case, the underpinning theory is described, the possible experimental realisations are discussed and the targeted applications listed, with specific mentions of the most significant examples. Although sometimes overlooked, X-ray imaging is all-pervasive in our society: medicine, industrial scans, non-destructive testing, security inspections and a vast number of scientific fields rely heavily on it. Hence, the potential impact of XPCi is immense.

How humanity came to contemplate its possible extinction.From forecasts of disastrous climate change to prophecies of evil AI superintelligences and the impending perils of genome editing, our species is increasingly concerned with the prospects of its own extinction. With humanity's future on this planet seeming more insecure by the day, in the twenty-first century, existential risk has become the object of a growing field of serious scientific inquiry. But, as Thomas Moynihan shows in X-Risk, this preoccupation is not exclusive to the post-atomic age of global warming and synthetic biology. Our growing concern with human extinction itself has a history. Tracing this untold story, Moynihan revisits the pioneers who first contemplated the possibility of human extinction and stages the historical drama of this momentous discovery. He shows how, far from being a secular reprise of religious prophecies of apocalypse, existential risk is a thoroughly modern idea, made possible by the burgeoning sciences and philosophical tumult of the Enlightenment era. In recollecting how we first came to care for our extinction, Moynihan reveals how today's attempts to measure and mitigate existential threats are the continuation of a project initiated over two centuries ago, which concerns the very vocation of the human as a rational, responsible, and future-oriented being.

By the 1980s the Troubles in Northern Ireland had become a sophisticated conflict between two immovable objects: the security forces and the terrorists. With no end in sight and no compromise possible, it was decided that an 'acceptable level of violence' was the only attainable status quo. This is the story of the operations conducted by one eight-man section under the control of their corporal, and the challenges they faced. Years later, when one of those eight succumbs to his demons and takes his own life, the author recalls the events of his tour of duty in the province and its impact on lives - his own, those of his section, and those of the civilians from all sides of the conflict.
