Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, EarlyView.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

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

Advanced Science, EarlyView.
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.
