An Optically Transparent Water‐Based Metamaterial Absorber for Ultra‐Broadband EMI Shielding in Coal Mines

Advanced Science, EarlyView.
This study introduces a novel metamaterial absorber integrating water as a lossy medium with patterned indium tin oxide (ITO) films to achieve simultaneous optical transparency and ultra‐wideband electromagnetic absorption over 0.52‐40 GHz. It effectively overcomes the limitations of conventional opaque and bulky shielding materials, offering a ...

Decoding Trap States in Working 2D Perovskite Multi‐Functional Devices

Advanced Science, EarlyView.
Illustration of the photoluminescence spectrum and energy‐level landscape governing trap‐mediated carrier dynamics in 2D F‐PEAI photodetectors. A novel approach capturing dynamic trap occupation and retrapping in devices under operating conditions, directly links defect energetics to carrier transport and enhanced photoresponse in multifunctional ...

Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion

Advanced Science, EarlyView.
A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.
