Negative thermal expansion (NTE) is an intriguing physical property of solids, which is a
consequence of a complex interplay among the lattice, phonons, and electrons …

To meet strong demands for the control of thermal expansion necessary because of the
advanced development of industrial technology, widely various giant negative thermal …

There has been substantial renewed interest in negative thermal expansion following the
discovery that cubic ZrW 2 O 8 contracts over a temperature range in excess of 1000 K …

Rational control of photoluminescence against a change in temperature is important for
fundamental research and technological applications. Herein, we report an anomalous …

We show that silver (I) hexacyanocobaltate (III), Ag3 [Co (CN) 6], exhibits positive and
negative thermal expansion an order of magnitude greater than that seen in other crystalline …

Seeking structure-property relationships is an accepted paradigm in materials science, yet
these relationships are often not linear, and the challenge is to seek patterns among multiple …

We analyze the intrinsic geometric flexibility of framework structures incorporating linear
metal–cyanide–metal (M–CN–M′) linkages using a reciprocal-space dynamical matrix …

Multi-temperature X-ray diffraction studies show that twisting, rotation, and libration cause
negative thermal expansion (NTE) of the nanoporous metal− organic framework MOF-5 …

In general, the relatively modest expansion experienced by most materials on heating is
caused by increasing anharmonic vibrational amplitudes of the constituent atoms, ions or …
