What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...
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) 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.
Researchers have successfully combined a table-top laser-based extreme high-order harmonic source for short-pulse soft-X-ray absorption spectroscopy in the water window with novel flatjet technology.
Over the last 10 years an increasing number of studies combining Raman spectroscopy with Synchrotron Radiation (SR) based techniques like X-ray Absorption Spectroscopy (XAS) have been reported. Such ...
What is X-ray absorption spectroscopy and how could I utilize it? X-ray absorption spectroscopy (XAS) is a well-established and powerful method to obtain information on structural and chemical ...
X-ray Absorption Spectroscopy uses the tunable broadband X-ray radiation delivered by synchrotrons to provide electronic and structural parameters for the metal-containing active sites of ...
XES is an element-specific method primarily used to analyze the partially occupied electronic structure of materials. The technique is one of the photon-in-photon-out spectroscopies in which an ...
