ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Fenton‐like Reactivity on Fe3O4 Nanozymes Driven by Charge Transfer and Interfacial Water
In magnetite nanozymes, subsurface Fe2⁺ donates electrons to H2O2, forming fleeting Fe(IV)═O and •OH species. The process couples charge flow, water‐mediated reactivity, and nanoparticle oxidation in a dynamic Fenton‐like cycle. Abstract Magnetite (Fe3O4) nanoparticles, widely recognized as inorganic nanozymes due to their enzyme‐like catalytic ...
