A combined QEXAFS/XRD method for on-line, in situ studies of catalysts: Examples of dynamic measurements of Cu-based methanol catalysts
TL;DR: In this paper, the authors developed a new in situ method which allows high quality XRD and EXAFS to be obtained on-line under ideal catalytic conditions, which enables a much better structural description of catalytic materials which typically contain both crystalline and X-ray amorphous structures.

Post-test evaluation of oxygen electrodes from solid oxide electrolysis stacks
TL;DR: In this paper, the oxygen electrodes from two solid oxide electrolysis stacks that performed high-temperature steam electrolysis (HTSE) and produced hydrogen for 1000 and 2000 h, respectively, were examined using X-ray fluorescence, X-Ray absorption near edge structure (XANES), four-point resistivity, scanning electron microscopy, energy dispersive spectroscopy, Xray diffraction and Raman micro-spectroscopy to determine possible causes for the degradation in stack performance over the test periods.

TL;DR: In this article, the coordination environment of Fe(II) has been examined in seven anhydrous ferrosilicate glasses at 298 K and 1 bar using 57Fe Mossbauer, X-ray near edge structure (XANES), UV-Vis-NIR, and magnetic circular dichroism (MCD) spectroscopies.

The Relationship between the Structure and Activity of Nanometer Size Gold When Supported on Mg(OH)2
TL;DR: In this article, Debye function analysis was used to analyze the catalysts of Au supported on Mg(OH)2 and showed that only catalysts with Au-size distributions below 1 nm in size were found to be active for CO oxidation.
