Gold Becomes Reactive Under Megabar Pressures, Forms Stable Hydride

Researchers compressed gold in a hydrogen-rich environment to megabar pressures (>110 GPa) using a diamond anvil cell and, with ultrafast diffraction from the European XFEL, observed hydrogen incorporation into gold to form a stable gold hydride. The result shows gold’s noble behavior can break down under extreme planetary-core-like conditions, potentially altering models of gas giant interiors and suggesting new metallic hydride materials. The hydride persists only under high pressure; releasing pressure causes hydrogen to escape and gold to revert to its original state.

"California's X-Ray Laser Revolutionizes Atom Filming with Unprecedented Power"

California's SLAC National Accelerator Laboratory has announced the "first light" of the Linac Coherent Light Source (LCLS) II, the world's most powerful X-ray laser. Capable of producing a million X-ray flashes per second, the LCLS II offers unprecedented detail at the atomic scale, potentially enabling new discoveries in fields such as quantum events, chemical processes, and drug development. The laser's advanced technology includes a superconducting accelerator, cryogenic modules, and undulators. The LCLS II is expected to attract researchers from around the world and facilitate groundbreaking experiments in various scientific disciplines.

Revolutionizing X-Ray Imaging with Interferometry

Researchers at the German Electron Synchrotron (DESY) have successfully demonstrated a novel x-ray imaging technique based on Hanbury Brown and Twiss interferometry, which can be used to image the structure of emitters on a copper film. The technique could eventually enable single-particle imaging of biomolecules and catalysts at the atomic scale, and, with sufficient time resolution, characterization of their reaction dynamics. The development of x-ray free-electron lasers (XFELs) has helped in this regard by making possible the generation of high-intensity x-ray pulses with femtosecond or even shorter durations.
