Structural transformations in pure and Ba-doped PbSc$_{0.5}$Nb$_{0.5}$O$_3$ u...
Lead scandium niobate (PSN) belongs to the class of perovskite-type relaxor ferroelectrics, which are among the key functional materials. Due to their structural complexity, the... -
High-pressure studies of inorganic azides
This proposal seeks to identify and structurally characterise the high-pressure phases of the azide salts of sodium, silver, lead, and the ammonium ion. Azides are examples of... -
A high-pressure study of monovalent bifluorides
This proposal seeks PEARL beam time to conduct the first high-pressure neutron diffraction study of the monovalent azides XDF2, where X = Na, ND4, Cs and Tl. In so doing, we... -
Phase Behaviour in Pyrazine and Tetramethylpyrazine.
Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of... -
Copy of: The Effect of Pressure on the Crystal Structure Titanium Tetrachloride
At ambient pressure and temperature TiCl4 is a fuming yellow liquid. On cooling it forma a solid composed of essentially isolated tetrahedral molecules; the same structure is...
