Printed Liquid Metal–Solid Metal Hybrid Electrodes for Stabilizing Liquid Platinum–Gallium Droplets During Electrocatalysis

open access: yesSmall, EarlyView.
A printed liquid‐metal catalyst platform is developed by confining Pt‐in–Ga liquid metal droplets within a tungsten nanoparticle matrix on porous Mo substrates. This architecture suppresses liquid metal droplet agglomeration and leaching, enabling durable and highly active electrocatalysis for both HER and CO2RR, with Pt‐dependent active motifs ...

Investigation of the impact of grain boundary hydrogen concentration on hydrogen embrittlement sensitivity of polycrystalline Fe: Molecular dynamics insights

open access: yesSmart Molecules, EarlyView.
Molecular dynamics simulations were utilized to explore the influence of grain boundary hydrogen concentration on the hydrogen embrittlement sensitivity of polycrystalline iron. This graphical abstract visualizes the corresponding microstructural evolutions, with results demonstrating that elevated hydrogen concentration reduces the yield and ultimate ...

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

open access: yessteel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...
