Sputtered NiCu Thin Films on Nickel Foam for Overall Electrochemical Water Splitting in Alkaline Media

Israel Journal of Chemistry, Volume 66, Issue 6, November 2026.
Ni:Cu (3:1) films, sputtered on nickel foam form self‐supported electrocatalysts for alkaline water splitting. The hydrogen evolution electrode (270 nm) overpotential at −50 mA cm−2 drops from 215 to 136 mV after 72 h, owning to Cu leaching . For oxygen evolution, it reaches 370 mV at 10 mA cm−2.

Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, Volume 28, Issue 19, 7 October 2026.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...
