Gas Adsorption‐Driven Electronic Modulation in WO3@Cu3(HHTP)2 Heterostructure: Mechanistic Origin of Selective Drift Resistance Room‐Temperature Formaldehyde Sensing

Small, EarlyView.
A WO3@Cu3(HHTP)2 heterostructure is engineered to achieve ultra‐sensitive, drift‐resistant formaldehyde detection at room temperature. Interfacial orbital hybridization and defect modulation enable adsorption‐driven electronic tuning, resulting in ppb‐level detection, rapid response, and high selectivity.

Deciphering Interfacial Electronic Interactions Between Iridium Oxide and Ni‐Based Supports for High‐Current‐Density Anion Exchange Membrane Water Electrolysis

Small, EarlyView.
This study develops binder‐free IrO2–Ni‐based electrodes through liquid‐phase synthesis to elucidate how Ni‐based support chemistry governs interfacial electronic interactions and oxygen evolution reaction (OER) performance. The IrO2–Ni2P electrode exhibits superior activity and durability, attributed to strong interfacial charge transfer that ...

Dual‐Site Activation of High‐Entropy Alloy Electrocatalysts via Ruthenium‐Induced Electron Transfer for Alkaline Hydrogen Evolution

Small, EarlyView.
Inspired by Ru‐induced electron redistribution in a high‐entropy alloy lattice, a Ru‐incorporated high‐entropy alloy is constructed to simultaneously activate Co/Ni dual sites, thereby boosting alkaline hydrogen evolution activity with low Ru loading.

Binary‐Solvent‐Programmed Single‐Step Inkjet Printing of Self‐Confined Micro‐Inlaid OLED Arrays

Small Methods, EarlyView.
Solvent‐programmed micro‐inlay inkjet printing enables lithography‐free, high‐resolution μ‐OLED arrays in a single step. A thermodynamically tuned 3:1 (w/w) chloroform/dichloroethane blend not only drives interfacial phase separation between the solute and polymers but also stabilizes droplet ejection, forming rim‐confined emissive domains in one pass.

Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

Small Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.
