Buried Liquid Metal Interfaces: Oxides and Surface Water‐Driven Hydrogen Bubbles

open access: yesSmall, EarlyView.
When liquid metal (EGaIn) is injected against substrates, its native oxide deposits at the buried interface via a tank‐tread mechanism. On glass (insulating) substrates, liquid metal reacts with surface water to generate hydrogen bubbles, with bubble size and density governed by humidity and surface hydrophilicity.

Machine‐Learning‐Assisted Discovery and Accelerated Synthesis of Metal Phosphosulfides

open access: yesSmall, EarlyView.
The synthesizability and band gaps of 909 hypothetical ternary phosphosulfides are evaluated by a combination of density functional theory and multi‐fidelity machine learning. The accelerated material development workflow is extended to the experimental domain by demonstrating a route to high‐throughput synthesis and characterization of virtually any ...

Oxidation‐Induced Internal Chemical Patterning in Copper–Gold Nanoalloys

open access: yesSmall, EarlyView.
Surface oxidation suppresses Au surface segregation and redirects Au transport to twin boundaries, replacing conventional core–shell formation with internal chemical patterning. Driven by Cu–Au mixing thermodynamics, defect‐mediated uphill diffusion creates alternating Au‐rich and Cu‐rich lamellae, revealing oxidation as a chemical pump for bulk ...

Rational Design of LiNi1‐xFexO2 Electrodes for Enhanced Oxygen Evolution Reaction Under Power‐Fluctuating Operations in Alkaline Water Electrolysis

open access: yesSmall Methods, EarlyView.
We develop Fe‐incorporated LiNiO2 for the OER in alkaline media, where Fe enhances Ni3+ oxidation state and optimizes eg orbital filling, significantly improving activity under power fluctuations. ABSTRACT The electrochemical performance of alkaline water electrolyzers is hindered by power fluctuations when integrated with renewable energy sources in ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

open access: yessteel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
