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

Small, 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.

High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

Smart Molecules, EarlyView.
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

Structural, Compositional, and Dielectric State Profiling in Label‐Free Single‐Cell Monitoring

Small Methods, EarlyView.
Label‐free single‐cell monitoring leverages distinct physical interactions to access structural, compositional, and dielectric states of cells, enabling non‐perturbative, repeatable, and information‐rich measurements across diverse biological contexts. This review organizes representative platforms by intrinsic state variables and connects measurement ...

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures

Structural Concrete, EarlyView.
Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.
