We intend to study a new class of materials known as 3D topological insulators. The electronic states in these materials have a non-trivial topology, different to almost all...

In this proposal we request beamtime on the Inter reflectometer to study the unexpected adsorption behaviour of the surfactant bis(2-ethylhexyl) sulfosuccinate caesium salt...

In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic...

The interface of CaCO3 (calcite) and water is of paramount importance in a number of key academic and industrial areas, including scale deposition in domestic and industrial...

In Sheffield, 9% efficient organic solar cells have been made using a new non-fullerene acceptor called ITIC, when blended with semiconducting polymers. GIWAXS measurements have...

Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we...

The structure of colloidal crystals (dispersions of particles that spontaneously order in a regular array) is known to be influenced by solid boundaries. However there are few...

The acyl-L-carnitines are a group of novel surfactants. Following our recent home laboratory work to synthesize, purify and characterize them, the aim of this proposal is to...

Myelin is the multilamellar structure that ensheaths axons and accelerates nervous impulses in the nervous system. The fine structure of myelin remains to be further...

The objective of this experiment is to use neutron reflectivity to study the surface structure and determine chemical depth profiles of Perflouropolyether-PDMS films in air and...

We ask for 8 days of beam time on CRISP to study the absorption and desorption of hydrogen and deuterium in Ti/Mg/Pd trilayer samples. Our specific objective is to understand in...

In the quest to find high-temperature ferromagnetic topological insulators (TIs), we have explored different transition-metal and rare-earth doped thin film and bulk samples...

Highly ordered dispersions of charged polymer particles that are tens or hundreds of nanometres diameter can be prepared. These are useful model systems for self-assembly and...

The proposed project is aimed at determining the nucleation/growth processes and structures (metal distributions and solvent population/distribution) of metallic films deposited...

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...

We wish to understand how the concentration of surfactant mixtures in solution affects adsorption at lower temperatures; in particular, we wish to see how the composition of the...

Here we propose a study that will contribute to the final challenges of PhD training programme (Emma Palin). We will study the electrochemical dissolution of a bi-metallic films...

Natural antimicrobials are of great interest, since they are antibiotics that act on the biological membrane, and it is believed that this makes it far more difficult for...

The main objective of this proposal is to study the structure of the interface between a semiconducting liquid crystal (LC) and a soft dielectric substrate for their potential...

Six days of OFFSPEC beam time is requested to expand our recent investigations of emergent magnetisation dynamics in ensembles of interconnected ring-shaped nanowires. In recent...
