In recent years, noble metal nanozymes have attracted considerable attention due to their remarkable catalytic activity16. Alloying further offers an opportunity to greatly extend the range of properties exhibited by noble metal nanozymes17. In particular, we are intrigued by the AuPd alloys, which sh...
reported [8] that the presence of metastable oxides on the surface of metal catalyst accelerates the CO2 conversion process by stabilizing the CO2− intermediate on the nano-interface compared to pure metallic interfaces. The authors modified the metallic surface of polycrystalline metals (Cu, Au,...
To derive further insights into the origins of the observed anomalous size effect and its relationship with compositional heterogeneity in this HEA, we employed atomistic simulations45to discern the transition of the size effect on the strength of HEAs, in comparison to that in pure metals and conv...
Currently, metal alloys that are conventionally utilized for orthopedic applications have a high corrosion resistance and biocompatibility [60]; for instance, Ti is an inert and safe material, which is widely used for permanent invasive implants. Ti produces minimum no desired effects on the patient,...
