Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

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 ...

Kβ X-ray emission spectroscopy (XES) is a promising technique for investigating Cu (I) sites as it detects photons emitted by electronic transitions from occupied orbitals. Here, we demonstrate the ...

Real-time chromium composition analysis during direct metal deposition of pure chromium and H13 tool steel materials was performed using optical emission spectroscopy of the laser-induced plasma. Four ...

Resonant inelastic X-ray scattering (RIXS) is a momentum-resolved spectroscopic method used to study vibrational and electronic excitations, combining inelastic scattering and spectroscopy to ...

Atomic Emission Spectroscopy (AES) identifies and quantifies elements by analyzing their unique emission spectra from plasma-induced excited states.

These include X-ray photoelectron spectroscopy, surface photovoltage measurement, and Kelvin force microscopy. Methods for sensitive local surface evaluation and rapid surface property mapping are ...

Using NASA’s Chandra X-ray Observatory, they detected the coronal X-ray emission from all three stars in the LTT 1445 system, including from the exoplanet-hosting star LTT 1445A. They also found that ...

X-ray photoelectron spectroscopy (XPS) is a spectroscopic technique for measuring the elemental composition of a sample. In this article, we discuss its use in nanotechnology research.
