Unveiling Surface Species Formed on Ni‐Fe Spinel Oxides During the Oxygen Evolution Reaction at the Atomic Scale

open access: yesAdvanced Science, EarlyView.
≈1 nm thick amorphous layer with a higher oxygen concentration is formed on the surfaces of pristine P‐doped NiFe2O4 and activated NiFe2O4. Such surface layer is thought to significantly promote the charge transfer kinetics compared to the oxyhydroxide layer grown on Ni1.5Fe1.5O4 during the oxygen evolution reaction.

Generalized Phase Tailoring of Arbitrary Orthogonal Polarizations in Meta‐Structure with High‐Order Geometric Symmetry

open access: yesAdvanced Science, EarlyView.
A generalized methodology is proposed for Cm (m ≥ 3) meta‐structures to achieve independent phase control of arbitrary orthogonal polarizations. By integrating orientation tuning with structural tailoring, this approach extends spin‐based designs to polarization‐diverse wavefront engineering, enabling multi‐functional and high‐efficiency meta‐devices ...
