Piezo‐Phototronic PVDF/HfO2/Nano‐Cu Heterostructured Thin Film for Flexible Self‐Powered Multimodal Sensing

open access: yesAdvanced Science, EarlyView.
Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Laterally Oriented Dendritic Passivation via In Situ Zn Reconstruction for Stabilizing NiMo Catalysts under Dynamic Electrolysis

open access: yesAdvanced Science, EarlyView.
This study highlights the effectiveness of Zn‐induced dendrite layers in enhancing the durability of NiMo HER catalysts under dynamic electrochemical conditions. Through in situ dendritic passivation, the Zn‐NiMo catalyst preserves catalytic active sites and mitigates irreversible Ni oxidation/hydroxylation during repeated load fluctuation.
