The spin state change of Fe3+ ions induced the paramagnetic Fe0.5Ni0.5OOH shell on the ferromagnetic Cu0.5NFe3Ni0.5 core via superexchange interaction, facilitating charge transfer and oxygen species ad(de)sorption for boosted OER performance.

Binding of Cu(ii) not only drives the conversion of the benign bis-His bound low spin heme(iii)–Aβ complex to the detrimental mono-His high spin form, even in the presence of excess Aβ, but it also forms the most toxic heme(iii)–Cu(ii)–Aβ species.
