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 ...

Advances in electron optics and X-ray detection are opening up the periodic table to one of the ultimate goals of microanalysis — single-atom spectroscopy. The researchers used their data to estimate ...

The work points toward a future in which X-ray beamlines, such as those at the APS, are more autonomous and better able to track complex chemical reactions as they happen. “This brings us closer to ...

Researchers in Japan are the first to have succeeded in detecting single atoms using X-ray spectroscopy. Although a difficult technique, the work is an important step forward in studying and ...

A major advance in solution phase soft-x-ray spectroscopy has been achieved utilizing a new liquid flatjet system, paving the way for novel steady-state and time-resolved experiments. A major advance ...

EDS works by focusing an electron beam onto the sample, which causes the sample to emit X-rays. Each element emits X-rays at unique energy levels, allowing for the identification and quantification of ...

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, ...

Recent news that x-ray spectroscopy is being introduced in forensic applications by scientists at Massachusetts' Thermo Scientific Laboratories proves that everything old becomes new again. X-rays ...
