Sub‐Nanometer Fe Clusters Confined in Carbon Nanocages for Boosting Dielectric Polarization and Broadband Electromagnetic Wave Absorption (Adv. Funct. Mater. 31/2022)

Abstract

Subnanometer Clusters In article number 2204370, Yixing Li, Xuefeng Zhang, and co-workers fabricate sub-nanometer iron clusters within nitrogen-doped carbon nanocages. Benefitting from their unique structures, the energy transformation between the relatively complex permeability and permittivity can be realized, which thus boosts the dielectric polarization and improves the electromagnetic wave absorption performance.
