Lattice and proton vibrational dynamics in Sc-doped BaTiO3 proton conductors
Proton conducting BaTi1-xScxO3Hx (BTS) perovskites are promising materials for proton conducting fuel cells in the intermediate temperature regime (200-600 °C). Compared to... -
Probing the mechanism of thermoelectric enhancement in Kondo insulator YbB12 ...
We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial... -
Simultaneous Raman and INS studies of high energy excitations in C70
The vibrational spectrum of C70 has been investigated by many techniques since it became available in significcant quantities. Previous INS spectra were recorded with small... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Paramagnetic excitations in BaFe2As2 at high temperature
One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or... -
How does a catalyst promoter affect the degree of hydrogen retention of iron-...
We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how... -

In conjunction with an industrial partner (Sasol Technology UK), the applicants have previously used INS measurements performed on the MAPS spectrometer to characterize a series... -
Investigation into the reversibility of TiCl4 doped NaALH4 using MAPS
Hydrogen Storage still remains the technology bottleneck for a more widespread use of hydrogen. Solid complex hydrides such as amides, alanates and borohydrides have been... -
Solvent Segregation in Phase-Separated Li-NH3-MeNH2
We request 2 days on MAPS (or 3 days on MARI) to determine the extent of solvent segregation in a liquid-liquid phase-separated metal-amine: The Li-NH3-MeNH2 system. Recently we... -
How do modifiers affect performance in iron Fischer-Tropsch catalysts?
The applicants have recently completed a series of INS studies on a model iron Fischer-Tropsch catalyst. Given the recent huge invigoration of F-T catalysis due to future global...
