Neutron scattering is a key tool for exploring molecular structure in materialsand compounds. At the TOPAZ single crystal diffractometer at Oak RidgeNational Laboratory (ORNL), samples are illuminated by neutron beams ofvarying energies and the scattered neutrons are recorded by an array ofdetectors. [...]

The study of radio galaxies (RGs) offers valuable insights into the complex dynamics between active galactic nuclei (AGN), host galaxies, and the surrounding medium. Among the diverse population of RGs, giant radio galaxies (GRGs) have a linear extent larger than 700 kpc and they are relatively rare compared to smaller RGs. [...]

The SASE3 soft X-ray beamline at the European XFEL has been designed and built to provide experiments with a pink or monochromatic beam in the photon energy range 250–3000 eV. Here, the focus is monochromatic operation of the SASE3 beamline, and the design and performance of the SASE3 grating monochromator are reported. [...]

Resonant absorption of a photon by bound electrons in a solid can promote an electron to another orbital state or transfer it to a neighboring atomic site. Such a transition in a magnetically ordered material could affect the magnetic order. [...]

A von Hámos spectrometer has been implemented in the vacuum interaction chamber 1 of the High Energy Density instrument at the European X-ray Free-Electron Laser facility. This setup is dedicated, but not necessarily limited, to X-ray spectroscopy measurements of samples exposed to static compression using a diamond anvil cell. [...]

This article demonstrates spatial mapping of the local and nanoscale structure of thin film objects using spatially resolved pair distribution function (PDF) analysis of synchrotron X-ray diffraction data. This is exemplified in a lab-on-chip combinatorial array of sample spots containing catalytically interesting nanoparticles deposited from liquid precursors using an ink-jet liquid-handling system. [...]

Much of Earth’s carbon may have been stripped away from the silicate mantle by dense metallic-iron during core formation. However, at deep magma ocean conditions carbon becomes less siderophile and thus large amounts of it may be stranded instead in the deep mantle. [...]
