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 ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...

Upcycling of Disposable Face Masks into Water‐Resistant and Flame Retardant Foams

open access: yesAdvanced Functional Materials, EarlyView.
Disposable mask waste is upcycled into lightweight polypropylene‐based foams with tunable porosity and composite architectures reinforced by ear‐loop fibers. The sustainable solvent‐based process enables upcycling rates of 91% and solvent recovery of >90%.

All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.
