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 ...

The global pandemic has drastically changed working practices, with many researchers now undertaking ambitious analyses from home and pushing back the frontiers of science from their kitchen table.

When alkali metals like sodium dissolve in liquid ammonia, they produce a colorful spectacle that has puzzled and delighted chemists for centuries. The metals release electrons that give the solution ...

The initial oxidation behavior of metallic copper, tin, and three single-phase Cu-Sn alloys (an $\alpha$ phase solid solution alloy, and the intermetallic compounds ...

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, ...
