Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -

Thermoelectric materials provide an alternative route for refrigeration and power generation bydirect conversion between thermal and electrical energy. With high chemical... -
A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
High-Resolution High-Pressure Study of the Elpasolite Perovskite La2NiMnO6
This proposal sets out to investigate the high pressure behaviour of the double perovskitematerial with the chemical formula La2NiMnO6. The properties of this and related... -
Continued studies of the high temperature structural behaviour of Ca2Mn3O8
