Topology‐Enabled Finite‐Band Absorption Framework Based on a Bioinspired Nested Dual‐Loop Architecture

Advanced Science, EarlyView.
A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

BMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by
