High‐Performance X‐Band Electromagnetic Interference Shielding in Flexible Barium Hexaferrite/Cobalt‐Based Microwires/Silicone Rubber Ternary Composites via Magnetic–Conductive Synergy

Advanced Electronic Materials, EarlyView.
A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts

Hybrid Heterostructures of Nanostructured Si Membrane and MoS2 for Self‐Powered Photodetectors

Advanced Electronic Materials, EarlyView.
A scalable MoS2/Si nanomesh vertical heterostructure is developed for self‐powered photodetection. The nanostructured junction enhances conductivity, expands the active heterointerface, and enables a transition from photovoltaic to avalanche‐assisted operation, delivering markedly improved photoresponse over planar counterparts.
