Spin excitations in La2CoO4
We will use MAPS to measure the complete spin excitation spectrum of the quasi-two-dimensional S=3/2 antiferromagnet La2CoO4. The measurement is motivated by recent observations... -
Exploration of Magnetic Excitations at High Energy Transfers in Superconducti...
We propose to study two single crystals with nominal compositions Fe1.07Te and Fe1.18Te using the MAPS spectrometer. The amount of interstitial Fe controls the material¿s... -

Magnetic excitations of the model one-dimensional metal K0.3MnO3
Understanding the electronic properties of low-dimensional systems remains one of the central challenges of condensed matter physics. Although great progress has been made in... -
Characterisation of on-top hydrogen on fuel cell catalysts.
A key step in a fuel cell is the dissociation of hydrogen gas to provide protons and electrons by a catalyst. For low temperature fuel cells carbon black supported... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
The application of INS to examine high specification Fe Fischer-Tropsch catal...
Over the last 4-5 years the research team have been developing INS methodology that can be applied to investigate Fe Fischer-Tropsch (F-T) catalysts. The first stage of that... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -

Recent experiences applying INS to examine a series of nickel-based methane reforming catalysts have enabled a generic experimental methodology to be developed. In collaboration... -
INS study of the effect of particle size on the formation of beta-palladium h...
Finely divided, supported palladium particles are used as catalysts in many technical processes. However, there is still considerable potential to improve catalyst performance... -
The expoitation of the A, B, C spectral signatures of H-bonds.
Intermediate strength hydrogen bonds, H-bonds, are known to play a role in the reactions of surface bound species, especially on the widely used industrial substrate... -
The chemisorption of hydrogen on cobalt
Cobalt based catalysts are widely used within industry for Fischer-Tropsch synthesis (FTS) in the production of sulphur free diesel. Despite the wide application of cobalt... -
MAPS Investigation of the decompositon of LiNH2BH3
Ammonia borane, NH3BH3, has been extensively studied as a potential hydrogen storage material because of its high hydrogen content (19.6wt%) and relatively low decomposition... -
