High pressure behaviour of sulfuric acid tetrahydrate
Our previous work on sulfuric acid tetrahydrate (SAT) identified a monoclinic high-pressure polymorph, which forms at 5.35 kbar when the tetragonal low-pressure phase is warmed... -
Characterising new high-pressure phases of ammonia monohydrate
Over the past two years I have carried out high-pressure surveys of the ammonia monohydrate (AMH) phase diagram using a Paris-Edinburgh press mounted on the D20 beam-line at the... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Investigation into the “1/8 anomaly” in superconducting cuprates: La2-xBaxCuO...
The superconducting material La2-xBaxCuO4 (LBCO) exhibits an anomalous dip in Tc at the x = 0.125 composition at low temperature (>30 K). This is at odds with other...
