X-ray spectroscopy techniques (e.g. X-ray emission spectroscopy, X-ray absorption spectroscopy, etc.) are used in a variety of applications including in material science, astronomy, and biomedical.

This sharp jump in absorption is called the absorption edge. By tracking how X-ray absorption changes before, during and after this edge, researchers can watch the chemistry of a specific element ...

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.

Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays ...

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 ...

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray ...

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 ...

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.

An X-ray photoelectron spectrometer is an impressive bit of kit. The relatively low energy of the detected photoelectrons dictates that the experiments are performed in ultra-high vacuum. The ...

X-ray backscatter AIT uses a narrow beam of X-ray photons with energies, hv, less than 100 keV. 2 There are five basic interactions that can occur as X rays penetrate material. These are the ...
