Synchrotron Powder Diffraction Methods and Refinement Techniques
A new generation of hybrid powder diffraction instruments will provide increased access to high-energy (>30 keV) synchrotron X-rays and facilitate a variety of diffraction experiments that are either not possible or practical using conventional diffractometers in the home laboratory. The coupling of a beam with increased brightness, tunability, low divergence, and low emittance with the availability of fast area detectors, opens up the possibilities of new classes of experiments including: (1) PDF studies of nano-minerals and the testing of structure models; (2) micro-powder diffraction from heterogeneous mineral composites; (3) the development of whole nanoparticle models that include core structure, defects, surface reconstruction, and surface-sorbed species to provide more realistic descriptions of nanominerals; (4) in situ and time-resolved studies following the evolution of atomic arrangements in supersaturated solutions and the nano-particulates precipitating from them.
Figures & Tables
This volume presents the majority of topics in synchrotron science that are of use to the clay science community. The chapters presented in this volume serve not only as significant statements on the state of these applications, but also as useful primers to potential new users of synchrotron facilities.
