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 ...

Tailoring Crystallographic Texture Through Direct Ink Writing of Piezoelectric Ceramics
Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.A novel additive manufacturing approach is demonstrated, using needle‐like template particles with preferred crystallographic orientation that align during additive manufacturing. This combines freedom in geometrical design with local crystallographic control that can increase functional properties, here demonstrated as a doubling of the piezoelectric ...
