Hard X-ray spectroscopy - Principles and Experimental Design
What can XAFS tell us about electronic structure and local geometry? Absorption cross-section and EXAFS equation. Basic analysis: Fingerprinting, Linear Combination, Principle Component Analysis, Curve fitting. Beamline instrumentation: how X-rays get to the sample, how to measure X-ray Absorption Spectra. Measurement modes: transmission, fluorescence, total electron yield. Detectors: measuring currents and counting photons. Sample environment - ambient, cryo, in situ, in operando. Common mistakes and good practices in EXAFS experiment. XAS in plant, food and soil science

X-ray Fluorescence Imaging
Principle of XRI Advantages of using synchrotron lightsource for XRI BioXAS-Imaging beamline components and beamline specs Available techniques at the beamline that can be coupled to XRI. Emphasize the importance of complementary synchrotron techniques (bulk XAS, XRD, IR etc.) How to select a beamline (notes on what to consider for a strong proposal) Type of samples that can be analyzed at the beamline-emphasizing sample preparation and presenting images of datasets of various samples Importance of multi-spatial resolution imaging Data processing with PyMCA
