Tuning of Polar Domain Boundaries in Nonpolar Perovskite.
Advanced materials (Deerfield Beach, Fla.) 35:11 (2023) e2207665
Abstract:
Domain boundaries in ferroic materials are found to have various physical properties not observed in the surrounding domains. Such differences can be enhanced and bring promising functionalities when centrosymmetric nonpolar materials encounter polar domain boundaries. In this work, a tunable polar domain boundary is discovered in an antiferroelectric single crystal. Under a small stress or electric field, the density, volume, and polarity of the boundaries are successfully controlled.Formation of a meltable purinate metal-organic framework and its glass analogue.
Chemical communications (Cambridge, England) 59:6 (2023) 732-735
Abstract:
The chemistries that can be incorporated within melt-quenched zeolitic imidazolate framework (ZIF) glasses are currently limited. Here we describe the preparation of a previously unknown purine-containing ZIF which we name ZIF-UC-7. We find that it melts and forms a glass at one of the lowest temperatures reported for 3D hybrid frameworks.Phase transition hysteresis at the antiferroelectric-ferroelectric boundary in PbZr1−xTixO3
