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 ...

Free-electron laser (FEL) sources can generate tunable short-wavelength coherent pulses that can be used for studying structure and dynamics of matter in different forms. In this open collection, we ...

High-Pressure Photoelectron Spectroscopy (HPPES) advances catalysis research by enabling real-time surface analysis under ambient and high-pressure conditions.

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 ...
