X-rays, a type of electromagnetic radiation with wavelengths from 0.01 to 10 nanometers, pack enough energy to pierce materials and interact with inner-shell electrons. 1 When they hit a sample, ...
A recent article in Nature Communications examined interactions between ionomers and catalysts in proton exchange membrane fuel cells (PEMFCs), focusing on how carbon support morphology and porosity ...
Abstract: In the recent past, the interest to perform X-ray Absorption Spectroscopy (XAS) experiments with laboratory sources has increased. Within this context, the LabXAS project aims to develop a ...
(a) Schematic of the liquid cell for XAS analysis of metal porphyrin complexes in aqueous solutions. XAS spectra of the central metals were obtained at the Fe or Co L 2,3-edge and those of ligands ...
Herein, the O K-edge X-ray absorption spectroscopy (XAS) profile of an aqueous acetonitrile solution presented a distinct sharp peak not commonly observed in the corresponding profile of liquid water.
X-ray Absorption Spectroscopy (XAS) is a powerful and versatile analytical technique that provides unique, element-specific insights into the oxidation state, local atomic structure, electronic ...
