Exclusive Se‐O Coordination and Fe‐doping Complementation: A Catalytic Strategy for Enhanced Sulfur Redox in Li‐S Batteries

open access: yesAdvanced Science, EarlyView.
Exclusive Se‐O coordination and Fe‐doping complementation significantly improve conductivity and modulate the d‐band centers, which strongly anchor polysulfides in bidirectional catalysis and reduce the energy barriers for the Li2S nucleation and dissociation, achieving high‐apacity retention, exceptional rate capability, and stable cycling capability.

Piezoelectric‐Metal Phononic Crystal Enabling GHz Tunable Ultrahigh Q Quasi‐BIC Mode

open access: yesAdvanced Science, EarlyView.
This study introduces a piezoelectric–metal phononic crystal design based on suspended LiNbO3 thin film that realizes quasi‐BIC resonance. The device achieves GHz operation with an ultrahigh quality factor (≈6.5 × 104) and efficient electrical tunability at low voltage.

Unleashing the Potential of Raman Spectroscopy to Estimate PEDOT:PSS Doping Level and Crystalline Morphology

open access: yesAdvanced Science, EarlyView.
Herein, the correlational changes of each PEDOT Raman peak to morphology and doping level are identified. Two equations are derived to estimate PEDOT π–π spacing and doping level from Raman spectra (from which mobility is also extracted). GIWAXS and XPS results validate the estimation equations.

DNA‐Inspired Multi‐Functional Double‐Cross‐Linking Self‐Healing Hydrogel Promotes the Healing of Diabetic Wounds

open access: yesAdvanced Science, EarlyView.
A self‐healing hydrogel crosslinked with dynamic nucleobase‐mimetic bonds delivers curcumin‐loaded exosomes. It promotes diabetic wound healing via a synergistic combination of antibacterial, anti‐inflammatory, pro‐angiogenic, and immunomodulatory mechanisms, providing a comprehensive therapeutic approach.
