Contactless Tracking of Decomposition in Self‐Reporting Ceramic Cr‐Al‐B Coatings

open access: yesAdvanced Materials Interfaces, EarlyView.
Proof of concept for contactless tracking of decomposition in self‐reporting ceramic Cr‐Al‐B coatings in extreme environments by contactless resistivity measurements is demonstrated. To verify the results, high resolution in situ and ex situ methods are employed.

Modulating D33 Coefficients Through In Situ AgF and Ag2O Growth in PVDF Composites for High‐Performance Piezoelectric Nanogenerators

open access: yesAdvanced Materials Technologies, EarlyView.
In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.
