The identification of novel physical properties of interest is not limited to mechanical properties, but can also be extended to the thermal response of materials. To give one example of this, Liu et al. studied the anomalous thermal expansion in the calcium squarate framework, showing that it combined negative thermal expansion (NTE) in volume, and uniaxial zero thermal expansion (ZTE) along a specific crystallographic axis. Both features are observed over an usually large temperature range, and find their root in the specific binding of the bridging squarate ligand and its transverse vibration modes. 19 Tuperssuatsiaite is a clay mineral named after Tuperssuatsiat Bay in Greenland, its composition is Na 2 Fe 2 Mn[Si 8 O 20 ](OH) 2 • 6H 2 O. 20 DB-bdc = 2,5-dibutoxy-1,4-benzenedicarboxylate, dabco = dabco=1,4diazabicyclo[2.2.2]octane. 21 We borrow the adjective "metamechanical" from Swiss sculptor Jean Tinguely .
