High-temperature behaviour of ammonium dihydrogen phosphate [PDF]

open access: yesJournal of Physics: Conference Series, 2017
For over five decades, the high-temperature behaviour of ammonium dihydrogen phosphate, NH4H2PO4, has been a controversial subject; while initial works associate ionic conductivity increase around Tt=153°C to a physical transformation (structural phase transition), later research supports the chemical nature of the transformation.

p‐Block Catecholates: A Century‐Old Platform for Hybrid Molecular Ferroelectrics

open access: yesAngewandte Chemie, EarlyView.
Ferroelectricity in the p‐block catecholato complex [Et4N][Cl‐Ge(cat)2] is demonstrated through polarization and piezoelectric measurements on thin films. Density functional theory calculations reveal the spontaneous polarization arising from the transition between centrosymmetric and polar structures, establishing p‐block catecholato complexes as a ...
