Dynamic Bending of Carbodiimide Anions Derives Uniaxial Negative Thermal Expansion in ZnNCN

Abstract Materials exhibiting negative thermal expansion (NTE), characterized by anomalous lattice contractions upon heating, have attracted considerable attention because of the unique attendant changes in crystal structure. A wide variety of compounds, including metal oxides, f...

Time-Temperature-Transformation Diagrams to Navigate the Nucleation and Quenchability of Metastable α-Li₃PS4

α-Li₃PS₄ is a promising solid-state electrolyte with the highest ionic conductivity among its polymorphs. However, its formation presents a thermodynamic paradox: the α-phase is the equilibrium phase at high temperature and transforms to the stable γ-Li3PS4 polymorph when cooled...
