Accelerating phase field simulations through a hybrid adaptive Fourier neural operator with U-net backbone

npj Computational Materials
Prolonged contact between a corrosive liquid and metal alloys can cause progressive dealloying. For one such process as liquid-metal dealloying (LMD), phase field models have been developed to understand the mechanisms leading to complex morphologies ...

Mesoporous Hexametallic High‐Entropy Alloy Nanotubes With Multicomponent Electronic Modulation for Efficient Bifunctional Catalysis

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Upgrades toward high-heat flux, liquid lithium plasma-facing components in the NSTX-U [PDF]

, 2016
Liquid metal plasma-facing components (PFCs) provide numerous potential advantages over solid-material components. One critique of the approach is the relatively less developed technologies associated with deploying these components in a fusion plasma ...

Development of 3D interconnected heterogeneous high-entropy alloy composites with enhanced multifunctionality via liquid metal dealloying

Journal of Materials Research and Technology
Liquid metal dealloying (LMD) is a selective extraction method wherein miscible elements are removed from a precursor alloy to obtain a three-dimensional (3D) interconnected structure.
