Determination of the on-top vibrational mode of the surface hydride in PdH.
Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the... -
Study of vibron stability in CeCuxAl4-x with x = 0.95 and 1.05
CeCuxAl4-x compounds crystallize in the ordered non-centrosymmeric tetragonal BaNiSn3-type structure (space group 107, I4mm). The strong interaction between crystal field (CF)... -
Magnetic fluctuations in the presence of charge order RbFe2+Fe3+F6
We propose to investigate the magnetic fluctuations in a charge ordered magnet. Rb(Fe2+Fe3+)F6 is loosely based on a distorted Kagome framework with alternating chains of... -
The Effect of Pressure on the Crystal Structure of Serine Hydrate
Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,... -
