Tracking Microhydration of the NaCl Rocksalt Molecule by Quantum Chemical Calculations and Penning Ionization Electron Spectroscopy in Helium Nanodroplets

Small Structures, Volume 7, Issue 5, May 2026.
This study combines quantum chemical calculations and high‐resolution Penning ionization electron spectroscopy in helium nanodroplets to investigate NaCl microhydration. It reveals the transition from contact to solvent‐separated ion pairs and quantifies hydration shell completion at about 34 water molecules.

Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.

Fast‐scanning small‐angle X‐ray scattering of hydrated biological cells

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 777-787, May 2026.
Fast‐scanning small‐angle X‐ray scattering on biological cells in aqueous environments reveals intracellular anisotropy and orientation, and allows for systematic assessment of radiation damage caused by the measurements.Due to their high penetration depth, X‐rays enable us to obtain information from the interior of whole unsliced cells. Scanning small‐

Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

Acta Crystallographica Section D, Volume 82, Issue 5, Page 471-483, May 2026.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...

The interaction between local melting and helium bubble in radiated aluminium under dynamic tension at high temperature and strain rates

Materials & Design
Materials exposed to extreme radiation environments (e.g., nuclear devices) accumulate substantial defects, such as helium (He) bubbles. These defects can alter material properties, including melting behavior, which has not been intensively explored ...

Things at Work: How Things Contribute to Performing Work

Journal of Management Studies, Volume 63, Issue 3, Page 1155-1191, May 2026.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.
