This book illustrates a few exemplary scientific topics addressed through the use of two complementary x-ray scattering techniques: inelastic x-ray scattering and x-ray powder diffraction. These scattering methods are the focus of the two main sections of this book. These sections are subdivided into chapters discussing specific applications. The general aim of this volume is providing a concise overview of the opportunities disclosed by these two experimental methods, providing some guidance for scientists picking up this field and, hopefully, inspiring more mature scientists towards the achievement of new advances in this area.

"Using the Nation of Islam as a vehicle, but largely through his own dedication, energy, and intelligence Malcolm X became an indefatigable leader of African Americans during the 1960s. This expansive volume examines one of the most controversial and heroic figures of the 20th century. Over 500 essays discuss how Malcolm X affected the world in which he lived and how the influence of people, issues, and events shaped his development as an international figure." "With more than 70 contributors from black studies, history, political science, sociology, philosophy, education, journalism, and psychology, the Encyclopedia combines the knowledge of a precise group of writers. Addressing a major social, religious, and political figure through their own disciplines, these authors flesh out both the diversity and the complexity of the world that defined Malcolm X."--Jacket.

X-ray free electron lasers (XFELs) deliver intense, coherent, femtosecond laser pulses in the X-ray range. The XFELs are opening two new research fields. One is to study ultrafast electronic and structural dynamics in various forms of matter. XFELs can make atoms and electrons in action visible. Another field is to study the non-linear interaction of the unprecedented intense X-ray pulse with matter. XFELs transform matter into its new form in extreme conditions that have never been reached. The present special issue provides an overview of the current status and future direction of the development of XFELs and the research fields opened by XFELs. Featured are reports on the status and plans of all FEL facilities in the world, i.e., FLASH in Germany, LCLS in USA, SACLA in Japan, FERMI in Italy, European XFEL, SwissFEL, PAL-XFEL in Korea, and Shanghai SXFEL in China. Reports are also included on instrumentations and on science at these facilities, as well as on the relevant theory.

Imaging methods such as X-ray microscopy are used in non-destructive material analysis to achieve resolutions in the sub micrometer range. Imaging optics are required, for which X-ray lenses are particularly suitable for photon energies above 10 keV. To ensure the universal use of these lenses with constant optical properties over a wide photon energy range, for the first time an X-ray zoom lens was developed in this work.

The cardiac function relies on an intricate molecular and cellular three-dimensional (3d) architecture of a complex, dense and co-dependent cellular network. Structural alterations of the cardiac structure can affect its essential function and lead to severe dysfunction of the organ. Cardiovascular diseases are the main cause of death worldwide with a rising incidence.However, it is not possible to give a generalized answer how the heart is formed. Up to now, cardiac structure as well as physiologic and disease-related tissue alterations of the tissue are mainly investigated by established 2d imaging methods such as optical microscopy or electron microscopy.This work presents a multiscale and multimodal X-ray imaging approach, which allows to probe the heart structure from the scale of entire intact murine hearts to the molecular organisation of the sarcomer structure.While the molecular structure of the actomyosin complex is probed by scanning X-ray diffraction,the 3d arrangement of the cellular network is investigated by propagation-based X-ray phase-contrast tomography. In this context, the concept of 3d virtual histology of cardiac tissue by X-ray phase-contrast tomography using laboratory sources as well as highly coherent synchrotron radiation is being further developed.

The x-ray is the only invention that became a regular diagnostic tool in hospitals within a week of its first observation by Roentgen in 1895. Even today, x-rays are a great characterization tool at the hands of scientists working in almost every field, such as medicine, physics, material science, space science, chemistry, archeology, and metallurgy. With vast existing applications of x-rays, it is even more surprising that every day people are finding new applications of x-rays or refining the existing techniques. This book consists of selected chapters on the recent applications of x-ray spectroscopy that are of great interest to the scientists and engineers working in the fields of material science, physics, chemistry, astrophysics, astrochemistry, instrumentation, and techniques of x-ray based characterization. The chapters have been grouped into two major sections based upon the techniques and applications. The book covers some basic principles of satellite x-rays as characterization tools for chemical properties and the physics of detectors and x-ray spectrometer. The techniques like EDXRF, WDXRF, EPMA, satellites, micro-beam analysis, particle induced XRF, and matrix effects are discussed. The characterization of thin films and ceramic materials using x-rays is also covered.
