Regulating Ligand‐to‐Metal Charge Transfer in UiO‐66(Zr)‐NH2 With Site‐Isolated Cu+ Centers for Efficient Photocatalytic H2O2 Generation

Small Science, Volume 6, Issue 8, August 2026.
Incorporation of highly dispersed Cu species into UiO‐66(Zr)‐NH2 introduces a competing ligand‐to‐Cu charge–transfer pathway that suppresses charge recombination and enhances photocatalytic H2O2 production. Combined PL, TRPL, TRIR, and variable‐temperature FTIR analyses reveal Cu‐mediated modulation of excited‐state dynamics and oxygen reduction ...

Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, Volume 97, Issue 8, Page 4326-4336, August 2026.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, Volume 50, Issue 8, Page 1125-1135, August 2026.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1847-1860, August 2026.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.
