Rational Grain Boundary Segregation Enables Long‐Term Thermally Stable, Catalytically Active, and CO‐Tolerant Nanograined Metals

open access: yesAdvanced Science, EarlyView.
Grain boundaries endow nanocrystalline metals with unique functions but suffer thermal instability. In boron‐segregated platinum, stability depends critically on segregation level—sub‐equilibrium concentrations strengthen boundaries, whereas oversaturation induces decohesion.

Stabilizing Stretchable Organic Transistors Through Small‐Molecule Additive Blending for Ultra‐Sensitive Pesticide Detection

open access: yesAdvanced Science, EarlyView.
This study introduces a small‐molecule additive to improve the stability of stretchable organic field‐effect transistor (OFET). Furthermore, stretchable OFET‐based pesticide sensors with extended‐gate electrodes are constructed. It achieves highly sensitive and precise detection of chlorpyrifos pesticide, reaching a detection limit as low as 0.032 ppb.

Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

open access: yesAdvanced Science, EarlyView.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...
