Carbonization Tuned Core‐Shell Fe3O4@C Nanostructures with Enhanced Electromagnetic Wave Absorption

open access: yesAdvanced Materials Interfaces, EarlyView.
The core‐shell structured Fe3O4@C composites are prepared by employing an in situ polymerization and carbonization treatment method. The effect of carbonization temperature on electromagnetic wave absorption of H‐FO@C composites is symmetrically analyzed, and the impedance matching and attenuation ability are improved significantly by controlling ...

Time‐ and Frequency‐Domain THz Imaging for the Characterization of Subwavelength Tags in Anticounterfeiting Devices

open access: yesAdvanced Materials Technologies, EarlyView.
Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...
