Active Learning‐Driven Discovery of Sub‐2 Nm High‐Entropy Nanocatalysts for Alkaline Water Splitting

Advanced Functional Materials, EarlyView.
High‐entropy nanoparticles (HENPs) hold great promise for electrocatalysis, yet optimizing their compositions remains challenging. This study employs active learning and Bayesian Optimization to accelerate the discovery of octonary HENPs for hydrogen and oxygen evolution reactions.

Nickel–Gallium-Catalyzed Electrochemical Reduction of CO2 to Highly Reduced Products at Low Overpotentials

, 2016
We report the electrocatalytic reduction of CO2 to the highly reduced C2 products, ethylene and ethane, as well as to the fully reduced C1 product, methane, on three different phases of nickel–gallium (NiGa, Ni3Ga, and Ni5Ga3) films prepared by drop ...

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

Advanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Excitonic Emission Modulation in GaSe/MoS2 Van Der Waals Heterostructure Via Plasmonic Control of Interlayer Charge Transfer

Advanced Functional Materials, EarlyView.
Plasmonic hybridization enables control of light emission in 2D van der Waals heterojunctions. By stacking multilayer GaSe and monolayer MoS2 on a silver film, light emission is enhanced at the edges due to plasmonic effects. In the center, where these effects are absent, charge transfer led to reduced light emission.
