A new method turns noise into valuable data to enhance understanding of chemical reactions and material properties with unprecedented detail at the atomic level. The results of this research are now ...

Astronomers using JWST and other telescopes found a supermassive black hole floating between two colliding galaxies — not in either galaxy center, but embedded in shocked gas. Why it matters: If ...

Multilayer graphene-gated carbon nanotube (CNT) emitters are introduced to novel vacuum-sealed x-ray tubes. We characterized field emission performances and electron-beam (Ebeam) converging of the ...

A quiet, glowing gas cloud has been hiding in plain sight not far from Earth. For decades, astronomers have predicted that some of the galaxy’s molecular gas — the fuel for star birth — might be ...

Operando X-ray spectroscopy is a powerful tool for probing electrocatalyst dynamics—but intense X-ray exposure can distort structural insights. A recent article reveals flux- and dose-dependent ...

X-ray absorption spectroscopy (XAS) provides a powerful tool for in situ chemical speciation, but is severely limited by poor spectroscopic energy resolution. Here, we provide a systematic examination ...

We find that such building blocks can provide an excellent description of X-ray emission spectroscopy (XES) and RIXS spectra, but only if all nearest-neighbor atoms are included. This finding is ...

Field emission X-ray devices present numerous benefits compared to conventional X-ray sources, such as operating at lower temperatures, delivering enhanced spatial resolution, and consuming less power ...
