For the first time since X-rays were discovered in 1895, researchers have successfully performed X-ray spectroscopy to identify the element of a single atom at a time. The achievement takes ...

X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique ... oxide supports, and single-atom catalysts. XAS can identify the active sites, monitor the oxidation state and coordination ...

Researchers at Lund University in Sweden have developed a new technique for measuring the quantum state of electrons ejected ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have ...

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 ...

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.

We have a strong tradition in X-ray spectroscopy and materials science. Our wide variety of in-house and synchrotron based research methods include X-ray imaging, spectroscopies, scattering, their ...

Here, we review our recent experimental results to measure local properties by utilizing the newly developed ‘marker’ grazing-incidence X-ray photon correlation spectroscopy (marker GIXPCS).

X-ray Photoelectron Spectroscopy (XPS)is a highly sensitive technique for identifying and quantifying the chemical states of elements on the outermost surface of a solid. It is especially useful for ...
