Most materials expand upon heating. However, although rare, some materials contract upon
heating. Such negative thermal expansion (NTE) materials have enormous industrial merit …

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 …

The elastic behavior of a material can be a powerful tool to decipher thermal transport. In
thermoelectrics, measuring the elastic moduli—directly tied to sound velocity—is critical to …

Anomalous thermal expansion behaviour of several open frame-work compounds has been
extensively investigated using the techniques of inelastic neutron scattering and lattice …

Classical third‐order thermoelastic constants are generally derived from the theory of small‐
amplitude acoustic waves in isotropic materials during heat treatments. Investigating higher …

Material microstructures are presented with a coefficient of thermal expansion larger in
magnitude than that of either constituent. Thermal expansion can be large positive, zero, or …

Using molecular dynamics (MD) simulations, we show that metal− organic frameworks
(MOFs) constructed using octahedral Zn4O (CO2) 6 clusters linked via aromatic carbon ring …

The energy crisis can be met by switching to renewable energy sources. The present study
explores the physical and hydrogen storage capacity of XCdH 3 (X= K, Rb) by first-principles …

ZrW2O8 is obtained as microparticulate powder following traditional methods or as
nanoparticulate powder using an inverse micelle sol− gel synthesis strategy. As-prepared …

CaZrF6 and CaHfF6 display much stronger negative thermal expansion (NTE)(α L100 K∼−
18 and− 22 ppm· K–1, respectively) than ZrW2O8 and other corner-shared framework …
