Poisson's ratio had long been considered to be an intrinsic material property, confined within
a narrow domain and governed solely by the geometry of interatomic bonds. Materials with …

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 …

Scandium trifluoride maintains a cubic ReO3 type structure down to at least 10 K, although
the pressure at which its cubic to rhombohedral phase transition occurs drops from> 0.5 GPa …

Negative thermal expansion (NTE) of materials is an intriguing phenomenon challenging the
concept of traditional lattice dynamics and of importance for a variety of applications …

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 …

Auxetics display the anomalous property of expanding laterally when uniaxially stretched,
that is, a negative Poisson's ratio, a property that arises from 1) the presence of specific …

In this paper the method of parametric Rietveld refinement is described, in which an
ensemble of diffraction data collected as a function of time, temperature, pressure or any …

The use of machine learning for the prediction of physical and chemical properties of
crystals based on their structure alone is currently an area of intense research in …

Over the past several decades, research on anomalous thermal expansion materials has
been rapidly growing, and increasing numbers of compounds exhibiting negative thermal …

Bulk thermal expansion properties of 19 members of the A2M3O12 family of tungstates and
molybdates were determined from room temperature to 800° C. The observed behavior …
