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 ...

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.

The many-body interaction of charges (electrons) and nuclei (phonons) plays a critical role in determining the properties and functionalities of molecules and solids. The exact correlated motion of ...

X-ray spectroscopy measurements that previously needed to be done at a synchrotron facility could become available to a broader audience thanks to a new tabletop system (Anal. Chem. 2022, DOI: 10.1021 ...

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

What is Scanning Transmission X-ray Microscopy (STXM)? Scanning Transmission X-ray Microscopy (STXM) is a powerful imaging technique that combines the principles of X-ray spectroscopy and microscopy ...

As the acronym suggests XPS (X-ray photoelectron spectroscopy) is a spectroscopic technique. An XPS spectrum is displayed as the number of photoelectrons collected by the detector as a function of ...

The basic physical process of irradiating a material with photons of a known energy and measuring the ejected photoelectrons has remained unchanged over six decades since it was first commercialized.
