Thermal, vibrational, and thermoelastic properties of Y2Mo3O12 and their relations to negative thermal expansion
(American Physical Society, 2014-07-21)
Y2 Mo3O12, a material that exhibits negative thermal expansion (NTE) from 10 to 1173 K, offers an excellent opportunity to examine relationships between NTE and other physical properties over a wide temperature range. We ...
The heat capacities of thermomiotic ScF3 and ScF3–YF3 solid solutions
Scandium trifluoride (ScF3) exists in a cubic ReO3 structure that exhibits negative thermal expansion from 10 to 1100 K, while substituted Sc1−x Y x F3 materials display the same behavior at room temperature but transition ...
Relating 139La Quadrupolar Coupling Constants to Polyhedral Distortion in Crystalline Structures
(American Chemical Society, 2015-10-26)
A broad series of crystalline lanthanum oxide-based materials has been investigated through high-field 139La solid state nuclear magnetic resonance (ssNMR) spectroscopy and ab initio density functional theory (DFT) ...
