In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

Small, EarlyView.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

Small, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...
