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 ...
Researchers develop a new XPS technique enabling surface studies at atmospheric pressure, enhancing real-world chemical ...
Photoelectron spectroscopy (PES) is a surface-sensitive analytical technique that provides information about the elemental composition, chemical state, and electronic structure of a material's surface ...
A recent study saw the Thermo Scientific™ K-Alpha™ X-ray Photoelectron Spectrometer (XPS) System employed in an investigation ...
Integrating XPS imaging in surface chemistry allows for detailed analysis of elemental distribution, crucial for improving ...
For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...
As a key precursor in the formation of new particles, sulfuric acid (H 2 SO 4) plays an important role in the formation of aerosols and clouds in the atmosphere. Gas-phase sulfuric acid molecules can ...
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 ...
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 ...
