The structure of methane water fluid mixtures at high pressure
We have recently discovered that above 2 GPa in the liquid/fluid forms water and methanebecome miscible in proportions up to 33 mole% of methane. This proposal is for time to... -
Pressure & Temperature Phase Diagram of the Elpasolite Perovskite La2NiMnO6
This experiment will examine the pressure and temeprature phase diagram of the elpasolite perovskite La2NiMnO6. The sample will be studied in the pressure range of 0-9 GPa at... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
Pressure dependent magnetic structure characterization of the Q1D compound Na...
NaCr2O4 is a Q1D TMO that offers a rich range of properties from the view point of fundamental science as well as from the view point of applied science. Indeed on one hand... -
High Pressure Cation Ordering in ScVO3, InVO3 and the Sc(1-x)LuxVO3 Solid Sol...
We propose an investigation of highly tilted AVO3 perovskites. These phases are only accessible under high pressure. We propose to follow the bixbyite to perovskite high-P phase... -
High-Pressure Structural Behaviour of 2,2,2-trifluoro-ethanol
In the mono-alcohols (ROH) there is a competition between the packing requirements of the R-group and for the hydroxyl groups to be sufficiently close for hydrogen bonding to... -
Formation and Structural Properties of Non-Stoichiometric Molybdenum Hydride
There is significant renewed interest in the super-conductivity of hydrogen-rich materials ever since the reported superconductivity of H2S at 203 K . As a result there is... -
