Proton transfer in aqueous systems is a fundamental process occurring constantly around us. It involves a molecule losing a proton, which then associates with another molecule. Given its significance ...

X-ray spectroscopy encompasses a suite of powerful, element-specific probes that reveal the electronic structure, chemical state and local geometry of matter. Techniques such as X-ray absorption ...

Absorption spectroscopy is a fundamental tool for probing molecular structure 1 . However, performing absorption spectroscopy on individual molecules is challenging because of the low signal-to-noise ...

The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented ...

A groundbreaking superconducting X-ray spectrometer has begun operation at BESSY II, giving Europe its first TES-based system and boosting photon detection efficiency by up to 1,000 times. The 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 ...

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 ...

With a novel approach to X-ray spectroscopy, researchers are now able to capture detailed, ultrafast snapshots of electron interactions. Newswise — In a leap forward for atomic-scale imaging, ...

Raman spectroscopy, unlike infrared, reaches sub-micrometer resolution but is hindered by weak signals and fluorescence ...

Newswise — Artificial intelligence (AI) is transforming nearly every branch of science. And researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory are helping lead the way.
