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 and "Hourglass" Dispersion in the Model High-Tc superconduct...
The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
Electronic state of Co3+ in LaCoO3
We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the... -

Nitric acid plays important roles in the atmosphere, in all aggregate states and combined with water.During the last periode we were running the proposal RB1110207 "Metastable... -
Mapping magnetic excitations in insulating phase of NaFe0.52Cu0.48As
Magnetism is believed to be linked to superconductivity in cuprates and iron pnictides. However while the parent compounds of cuprates are Mott insulators, the parent compounds... -
The adsorption of methyl proprionate on silica catalysts.
Commercial routes for the manufacture of methyl methacrylate monomer have recently been developed that involve the reaction of esters over modified silicas, which are amphoteric... -
