He discusses molecular structure and electronic structure, including x-ray and electron spectroscopy methods; the crystallographic structure and microstructure determination, including diffraction, reflectometry, and scattering; the imaging and other real space mapping methods based on x-rays; the anomalous dispersion of chemical elements and uses in elemental, chemical, and orbital x-ray contrast variation; the surface and bulk sensitivity of the methods; organic and bio-organic samples; x-ray electrochemical case studies of batteries, fuel cells, and photoelectrochemical cells; and how x-ray based data can match the conductivity data from some materials.
