The process begins with the absorption of X-ray photons by atoms in the material, leading to the ejection of photoelectrons. By analyzing the energy spectrum of these photoelectrons, information about ...

X-ray Photoelectron Spectroscopy (XPS): A surface-sensitive quantitative spectroscopic technique that can identify the elemental composition and chemical state of materials. Auger Electron ...

Energy-Dispersive X-ray Spectroscopy (EDX): A technique used in conjunction with electron microscopy to analyze the elemental composition of a sample by measuring the energy of emitted X-rays.

EDS works by focusing an electron beam onto the sample, which causes the sample to emit X-rays. Each element emits X-rays at unique energy levels, allowing for the identification and quantification of ...

Energy Dispersive X-Ray Spectroscopy (EDS) is a microanalysis method used in addition to scanning electron microscopy (SEM). EDS provides chemical information by detecting x-rays released from a ...

The Helsinki Center for X-ray Spectroscopy is a unique research and education infrastructure serving users from both academia and industry in their leading-edge research, development and innovation.

It is similar to NMR spectroscopy, but instead of exciting the spins of atomic nuclei, EPR excites the electron spins of unpaired electrons. This technique has a wide range of applications, ...

A study appearing in Proceedings of the National Academy of Sciences introduces a trimetallic catalyst—including nickel (Ni), ...
