In this proposal we investigate the adsorption of the key dispersant additive, sodium polyacrylate, used in colloidal systems using neutron reflection on aluminium oxide, with...

This application seeks to discover whether the catalyst handling protocols refined for INS measurements of a variety of heterogeneous catalytic systems can be further exploited...

We have developed a new class of ferritic steels strengthened by hierarchical precipitates (HPs) of Ni2TiAl/NiAl or a single precipitate (SP) Ni2TiAl for applications as...

Powder diffraction offers an accessible and accurate method to determine the phase abundance in crystalline mixtures. Unfortunately, only the crystalline components of the...

In this project we propose to study the adsorption of methane onto a model mineral surface. This type of study is crucial to the understanding of the temperature dependence of...

Recent infrared measurements by one of the applicants (GR) have shown that CO and CO2 adsorption on alumina-supported palladium catalysts form a variety of carbonate species. In...

Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when...

Copy Of: Structural disorder in Gamma Alumina: Composition 3

Metal oxides(MO) are widely used in technological applications especially for catalysts and supports for catalysts. We propose to use the inelastic response of H2 adsorbed on...

Small gold nanoparticles (1-5 nm) supported on metal oxides are extremely active catalysts for C-C coupling, aerobic oxidations and selective hydrogenations. The interaction of...

This proposal presents a comparative study of the adsorption of three key chemical groups onto an important technological substrate, viz. fatty acid salt (Sodium hexanoate),...

Several interesting results have emerged in studies of Aerosol-OT at the sapphire/solution interface that relate to effects of counter-ions, insensitivity to pH as well as the...

For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts...

Structural disorder in Gamma Alumina: Composition 2

Previous data obtained from neutron reflection shown in Figure 1 has clearly shown that the surface excess of some surfactants when adsorbed from aqueous solution to a sapphire...

INS is an ideal means of probing the complete vibrational density of states of water adsorbed on the surface of metal oxide nanoparticles with minimal interference from the...

Materials adopting the apatite structure are gaining an increasing importance as potential solid-oxide fuel cell electrolytes and for the chemical stabilisation of high level...

A recent experiment has provided clear evidence for a large maximum in the adsorption just below the critical micelle concentration of the surfactant hexadecyl trimethyl...

We have recently demonstrated that we are able to obtain structural information about adsorbed hydrogenous species from a variety of metal catalysts. We emphasise that this is a...
