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 ...

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 ...

Recently, ionic liquids have been recognized as the possible lubricants for metal/metal contacts. The wear and friction characteristics of the liquids are investigated using tribological experiments.

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 ...

The PHI VersaProbe XPS Microprobe is a multi-technique, ultra-high vacuum surface analysis instrument that is capable of producing focused, highly monochromatic X-ray beam that can be scanned over a ...

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, ...
