Stabilization of Cu Species in UiO‐66 Metal–Organic Framework for CO2‐to‐Methanol: Insights From Operando X‐ray and Electron Microscopy Studies

open access: yesSmall, EarlyView.
This study reveals how a zirconium‐based metal–organic framework (UiO‐66) stabilizes copper species during CO2 hydrogenation to methanol. Operando X‐ray spectroscopy, electron microscopy, and theory show that zinc promotes highly dispersed copper and suppresses particle growth, while the framework dynamically responds to reaction intermediates.

Supersampled Scanning Transmission X‐Ray Microscopy for High‐Resolution Vibration‐Independent Time‐Resolved Imaging

open access: yesSmall, EarlyView.
ABSTRACT Scanning transmission x‐ray microscopy (STXM) is a nanoscale imaging technique that can utilize several powerful contrast mechanisms for the quantitative mapping of chemical and physical materials properties. Spatial resolutions down to 7 nm at the soft x‐ray energy range have been demonstrated.

More Photocatalysis With Less Light in Polar Semiconductors—The Role of Pyroelectric Fields

open access: yesSmall, EarlyView.
The work demonstrates that the modulated solar irradiation enhances the photocatalytic degradation of methyl orange on BaTiO3 despite reducing the photon flux by about 50%, resulting in a net overcompensation of catalytic efficiency. The effect arises from pyroelectric polarization near the phase transition, triggered by infrared heating of water ...

Fractionation‐Free Protein Corona Quantification Through Synchrotron‐Based Small‐Angle X‐ray Scattering

open access: yesSmall Methods, EarlyView.
A fractionation‐free SAXS approach quantifies protein corona formation on silica nanoparticles under native conditions. By deconvoluting scattering from free and bound proteins, adsorbed mass is directly determined in simple and complex media. The method resolves adsorption regimes and thermodynamics, establishing non‐invasive, in situ characterization
