For many applications such as paints, foods and drug formulations, aggregation of colloidal particles is prevented by combining polymer and surfactant adsorption. Key to this...

The asphaltene fraction of crude oil is defined by its solubility parameters (insoluble in n-heptanebut soluble in toluene). Changes in conditions (temperature, pressure,...

Fish oocytes and embryos are complex cryobiological objects for which, successful cryopreservation has still not been achieved. This circumstance seriously restricts the...

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...

These experiments are part of a much broader programme at the University of Reading. focused on the use of water-soluble half-acetylated chitosan as a mucoadhesive polymer,...

Surfactants have been used to bind and disperse Pt and Ru nanoparticles during their synthesis. In this work, we propose to use SANS to determine the thickness and packing...

Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be...

The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman...

Muon nuclear quadrupolar level crossing resonance is not a well-known technique, however it is extremely powerful. There is a large interest in probing the muon stopping site...

Despite interest in microemulsions as drug delivery vehicles, there is a lack of structural understanding to justify the formulations used. The present study examines the use of...

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...

We have recently shown that acid washing of a carbon support prior to metal (Au, Pd) deposition enhances the activity of the resulting catalysts for the direct synthesis of...

Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for...

The tunnel magnetoresistive effect (TMR) is critically dependent upon interfacial disorder. Polarised neutron reflectivity will be used to characterise the magnetic roughness at...

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...

Topological insulators are 3D materials with a band gap in the bulk-electronic structure but with gapless, delocalized, surface states. The most studied topological insulator is...

We propose to make neutron reflectivity measurements of hydrophillic polymers covalently attached, via thiol chemistry, to the gold-water interface. In particular, we will...

We have recently used a combination of PNR and low energy muon spin rotation (LEM) to detect the coexistence of an induced SDW and superconductivity in the superconducting layer...

Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Muon studies of Au NPs encapsulated in 'SBA-15' silica are...

Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is...
