Electron Delocalization Induced by 3d–4f Orbital Hybridization of Co─Ce Atom Pairs Toward Enhanced Electromagnetic Wave Attenuation and Antibacterial Performance

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Co─Ce dual atomic configuration anchored on the surface of NC matrix has been constructed to regulate the local electron structure. The higher occupied states induced by the Co 3d‐Ce 4f orbital hybridization facilitate the formation of polarized electric fields, which in turn strengthens the polarization relaxation and partially repairs the effective ...

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.
