Salicylate‐Assisted Surfactant‐Directed Assembly Synthesis of Uniform Mesoporous ZnO Nanospheres for Gas Sensing Applications

SmartMat, Volume 7, Issue 2, April 2026.
A salicylate‐assisted surfactant‐directed assembly strategy was developed to construct monodisperse mesoporous ZnO (mZnO) nanospheres with well‐defined architectures, followed by the integration of ultrasmall Pt nanoclusters to generate abundant metal‐metal oxide interfaces.

Magnetic and Isotopic Analyses Unravel the Abundance and Sources of Magnetic Nanoparticles in Urban PM2.5

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Magnetic nanoparticles (NPs) are increasingly recognized as an emerging threat to ecosystems and human health, yet their mass concentrations and sources in urban atmosphere remain poorly characterized. Here, we developed a robust methodology for the extraction, quantification, and source apportionment of magnetic NPs in urban PM2.5.

Size‐Dependent Melting Behavior of Ultrafine Fault Rocks

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Dynamic weakening during earthquake ruptures is essential for accommodating fault slip and controlling seismic energy release. This weakening is localized within narrow principal slip zones (PSZs) that commonly contain nanoparticles in both natural and experimental faults.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.
