The iron containing superconducting system FeSexTe1-x has a similar phase diagram to the cuprate superconductors, in that a non-superconducting antiferromagnetic parent compound...

The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously...

Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close...

The objective of this proposal is to spectroscopically identify the nature of surface species formed during the addition of tert butyl hydroperoxide onto the surface of the...

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...

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...

Finely divided, supported palladium particles are used as catalysts in many technical processes. However, there is still considerable potential to improve catalyst performance...

The objective of this proposal is to identify the nature of species formed on the surface of the catalyst material when they are exposed to typical fuel cell feed stocks and...

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...

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...

The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to...

Since the discovery of high transition temperature (high Tc) copper oxide, many efforts have been made on the understanding of its electronic and magnetic properties. Although...

We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of...

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...

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...

There has been much research into the recently discovered iron based superconductors, but so far only the magnetic excitations at low energy have been investigated. We propose...

In collaboration with an industrial partner, the PI is seeking to use INS to help characterise a series of catalysts active for the important Fischer-Tropsch (F-T) process. As...

Steering and optimizing catalyst selectivity at ¿ simultaneously - adequate catalyst activity is a continuing challenge in chemical technology and of high economic impact. In...

In conjunction with an industrial partner (Sasol), the applicants have previously used INS measurements performed on the MAPS spectrometer to characterise a series of iron based...

Inelastic neutron scattering has been used to study adsorbed species on catalysts for more than 30 years. All of this work has one feature in common: they are all ¿snapshots¿ of...
