Opis książki

This book is a practical guide to help investigators choose the right experiment, carry it out properly and analyse the data to give the best reliable result. It book gives readers insights to extract what they need from the world of large scale experimental facilities like synchrotrons. Key features: * A no-nonsense introduction to the technique and applications of x-ray absorption spectroscopy * XAFS is now an everyday tool for the structural analysis of material science, biology and catalysts * Features Questions and Answers to support the student s learning through the book * Relevant to all working on synchrotron sources and applications in physics, materials, environment/geology, and biomedical materials * Four-colour representation to allow easy interpretation of images and data for the reader
