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

Advanced 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

Advanced 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

Advanced 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.

Unraveling Alkali Ion Electron Donation for Enhancing Heterogeneous Catalytic Oxidation

Advanced Science, EarlyView.
A new mechanistic pathway for potassium (K) ions as electron donors is identified by constructing single K ion chains confined within hexagonal WO3 tunnels. The as‐produced high‐electron‐density Kδ+ (0<δ<1) ions not only facilitate the formation of oxygen vacancies that behave classical electronic effect but, more importantly, also directly donate ...

Stable, Step‐Guided Growth of Planar Germanium Nanowires at 200 °C via the In‐Plane Solid‐Liquid‐Solid Mechanism

Advanced Science, EarlyView.
A comprehensive analytical growth model is developed to elucidate the key dynamic processes governing mass transport and catalytic droplet stability during in‐plane solid‐liquid‐solid (IPSLS) growth. A critical parameter window is identified, enabling the guided growth of ultralong and uniform germanium nanowires （GeNWs）with lengths exceeding 10 µm and
