Achieving Ultrawide Negative Thermal Expansion up to 1300 K via Structural Flexibility Engineering.
Developing novel open-framework negative thermal expansion (NTE) materials with both a strong NTE effect and a wide temperature range is crucial for thermal expansion control in high‑precision devices. Inspired by the concept of average atomic volume (AAV), continuous regulation of thermal expansion from positive to ze...
