Researchers developed an AI-guided method that dramatically speeds up a widely used X-ray technique known as X-ray absorption near-edge structure (XANES) spectroscopy. It does so with far less risk of ...

Soft X‐ray spectroscopy plays a pivotal role in astrophysics as it reveals the physical conditions of hot plasmas and energetic phenomena in the universe. By focusing on the soft X‐ray band—typically ...

Researchers have improved an ambient-pressure photoelectron spectroscopy instrument using hard X-rays and succeeded in photoelectron spectrometry under real atmospheric pressure for the first time in ...

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 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.

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.

Virtually every scientific field has made strides by harnessing light to study the properties of substances. This technique, called spectroscopy, has countless research applications, and innovations ...

New research shows that X-ray photoelectron spectroscopy (XPS) can give misleading analysis results due to an erroneous assumption during calibration. X-ray photoelectron spectroscopy (XPS) is often ...

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, ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...
