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, ...

X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy are two techniques used to study atomic structures. The main difference between these tools is that X-ray crystallography uses X ...

X-ray absorption spectroscopy is a powerful method used by chemists, biologists, and materials scientists to analyze solids, liquids, and gases. The technique can identify elements and provides ...

X-ray spectroscopy measurements that previously needed to be done at a synchrotron facility could become available to a broader audience thanks to a new tabletop system (Anal. Chem. 2022, DOI: 10.1021 ...

What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

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 ...

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 ...

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 ...

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 ...
