Integration of a high-entropy alloy (HEA) with nanozyme activity and piezoelectric material piezoelectricity is promising strategy to develop novel biofunctional for the repair infectious bone defects. Herein, heterojunction HEA (FeMnMoRuIr) zinc sulfide (ZnS) (HEA@ZnS) synthesized that exhibits enhanced activities. Moreover, hydrogel containing zein, sodium alginate, HEA@ZnS (ZeAHZ) antibacterial properties pro-osteogenic capability fabricated. Under acidic conditions, triggered by ultrasound, effect ZeAHZ enhances peroxidase-like sonodynamic efficiency produces large amount reactive oxygen species (ROS, ·O2- ·OH) collaboratively eliminating bacteria. superoxide-like effect-enhanced catalase-like scavenge ROS (·O2- H2O2) produce due cascade reaction, which provides favorable microenvironment cell growth. Further, generates electrical stimulation significantly promotes osteoblast proliferation differentiation. This study opens up new path designing biomaterial production/elimination pro-osteogenesis stimulation, has great potential accelerating regeneration.

Abstract Alloying strategies have proven effective in enhancing the properties of metallic materials. However, conventional alloying face significant limitations preparing nanoscale multi-alloys and continuous optimizing surface-active sites. High-entropy alloys (HEAs) display a broader spectrum unique due to their complex electron distribution atomic-level heterogeneity arising from stochastic mixing multiple elements, which provides diverse array binding sites almost energies. This review aims summarize recent research advancements synthesis multi-field applications HEAs. It emphasizes several commonly employed challenges synthesizing Finally, we present comprehensive analysis advantages HEAs for applications, emphasizing application trends related nanosizing multidimensionalization develop more efficient

Abstract The key to fully realizing the potential of high‐entropy alloys (HEAs) lies in balancing their inherent local chemical disordering with long‐range ordering required for electrochemical applications. Herein, we synthesized a distinctive L1 0 ‐(PtIr)(FeMoBi) intermetallics (HEIs) exhibiting nanoscale order and atomic scale short‐range disorder via lattice compensation strategy mitigate entropy reduction tendency. (PtIr)(FeMoBi) catalyst exhibited remarkable activity selectivity glycollic acid (GA) production electrocatalytic waste polymer‐derived ethylene glycol oxidation reaction (EGOR). With mass 5.2 A mg Pt −1 Faradaic efficiency (FE) GA 95 %, it outperformed most previously reported electrocatalysts selective production. lattice‐compensation effect promotes homogeneity Fe actives sites, facilitating co‐adsorption EG OH reducing energy barriers dehydrogenation OH‐combination processes. This approach effectively avoids formation low‐active sites commonly encountered HEA solid solutions, offering promising avenue exploring complex interplay between catalytic HEI structures.
