Dual‐Percolative Planar‐Heterojunction Photoactive System for High‐Performance Stretchable Organic Photovoltaics Enhancing Power Output under Strain

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐percolative planar‐heterojunction photoactive architecture enables intrinsically stretchable organic photovoltaics that combine high photovoltaic efficiency with enhanced mechanical robustness. Abstract Intrinsically stretchable organic solar cells (IS‐OSCs) are promising candidates for wearable power sources due to their ability to deform in ...

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

open access: yesAdvanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

An Ionic Gelation Powder for Ultrafast Hemostasis and Accelerated Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
An ultrafast ionic gelation‐activated hemostatic powder (AGCL) forms a hydrogel within ≈1 s upon contact with blood‐derived calcium ions. The AGCL powder enables rapid hemorrhage control, strong tissue adhesion, and enhanced healing. The powder's pre‐crosslinked polymer network ensures high blood uptake and stability, offering effective treatment for ...

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

open access: yesAdvanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.
