Optimizing Hybrid‐phase IrO2 Catalysts with Ti for Enhanced Oxygen Evolution Reaction for Proton Exchange Membrane Water Electrolysis

open access: yesSmall, EarlyView.
In this study, a hybrid‐phase Ti‐doped IrO₂ with TiO2 composite catalyst is developed, demonstrating remarkable OER performance, with 298.8 mV at 100 mA cm−2 and sustained performance over 25 h. Ti composite induces tensile strain, shortening the Ir─O bond distance and enhancing catalytic activity.

Chalcogenide‐Based Brain‐Inspired Photo‐Synapses for Neuromorphic Vision Sensor: An Experimental and Theoretical Study

open access: yesSmall, EarlyView.
A multifunctional optoelectronic synaptic device based on 2D SnS2 is presented, combining DFT‐predicted semiconducting properties (bandgap of 2.47 eV) with experimental memristive behavior for visual perception emulation. The device exhibits strong wavelength‐dependent photoresponse, ultralow operating voltage (0.1 V), and energy efficiency (0.345 nJ ...

Scalable Exsolution‐Derived E‐Ni/m‐MgAlOx Catalysts with Anti‐Sintering Stability for Methane Dry Reforming

open access: yesSmall, EarlyView.
A sintering‐resistant E‐Ni/m‐MgAlOx catalyst with exsolved Ni nanoparticles shows >1000 h stability in methane dry reforming, achieving cumulative greenhouse gas conversion above 20000 L·gcat−1 at 800 °C–900 °C. Abstract Sintering and carbon deposition are primary causes of deactivation in Ni‐based catalysts during methane dry reforming (MDR).

Large‐Scale Implementation of Vertical Sidewall and Vertical Multi‐Channel WS2 Nanosheet Field‐Effect Transistors for Area‐Efficient Integrated Circuit

open access: yesSmall, EarlyView.
In this work, the authors successfully demonstrate double‐gate vertical sidewall WS2 FETs and, for the first time, vertical multi‐channel WS2 NSFETs using CVD‐grown monolayer WS2. By optimizing dual‐step SiO2 sidewall profiles and employing high‐κ dielectrics, they achieve excellent subthreshold swing, suppressed short‐channel effects, and high ION ...
