Rare Metals, EarlyView.ABSTRACT This study introduces novel nonequiatomic TiZrCoCrMoCux (x = 0, 5, 10; at%) medium‐entropy alloys (MEAx) tailored for orthopedic implants, synergistically combining the biocompatibility of Ti‐based alloys, the wear resistance of CoCrMo alloys, and the antibacterial/osteogenic attributes of Cu. The alloy's microstructure, mechanical properties,

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils
Small, EarlyView.Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

Small, 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 ...

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice
Small Methods, EarlyView.Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.
