Graphene Quantum Dot‐Induced Microstrain for Framework Stabilization of High‐Entropy Prussian Blue Analog in High‐Current Alkaline Hydrogen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Efficient use of synchrotron radiation for macromolecular diffraction data collection

open access: yesProgress in Biophysics and Molecular Biology, 2005
In recent years, number of X-ray synchrotron beam lines dedicated to collecting diffraction data from macromolecular crystals has exceeded 50. Indeed, today most protein and nucleic acid crystal structures are solved and refined based on the synchrotron data.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

open access: yesAdvanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.
