Historical metallurgy is one of the most interesting topics of archaeometry but, in order to have a good level of characterization of artefacts by traditional analytical...

We propose to use SANS to probe the self organised formation of P3HT nanowires in a solution of deuterated chlorobenzene over a 48 hr period in order to better understand the...

We have been studying the interaction between nematic liquid crystals and interfaces. It has been found that a surface that anchors the director in a perpendicular orientation...

The aim is to measure any tendency towards phase separation in a nematic mixture to complement an adsorption study on the same mixture. The base is 4-pentyl 4¿- cyanobiphenyl...

Liquid crystals (LCs) are known to act as good lubricants, however, the reason for this remains unclear. One contributing factor is thought to be the formation of ordered layers...

The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from three differently deuterated versions of 8CB....

The proposal is to use previous established neutron reflection methods to observe the smectic layers that form at the surface of a nematic liquid crystal. In this proposal we...

We wish to determine the effect of various stabilisers on anisotropic pigment particles that are being developed for use in liquid crystal composites. We will investigate the...

The adsorption of a liquid crystal dopant to a surface can have a significant impact on its properties such as electro-optic response and lubrication. Both the interesting...

Polymers adsorbed or otherwise attached to interfaces provide an extremely powerful tool to control the forces that act between interfaces. The functionality of these attached...

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 proposal is to use previous established neutron reflection methods to observe the smectic layers that form at the surface of a nematic liquid crystal. In this proposal we...

The Pitt Rivers is Oxford University¿s museum of anthropology and world archaeology. The Japanese material includes a large number of items of metalwork. Amongst these, the...

The adsorption of a liquid crystal dopant to a surface can have a significant impact on its properties such as electro-optic response and lubrication. The interesting adsorption...

Edible biopolymers are routinely used in the encapsulation and controlled release of bioactive ingredients (e.g. medicines, nutrients, flavours). Common encapsulants are in...

A second-generation surface force style apparatus has been developed to probe the inter-surface and near-surface structures under compressive forces. Systems of current academic...

The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from the n=8, 10 and 12 homologues of the nCB series...

The aim is to measure the preferential adsorption of one component in a nematic mixture. The base is 4-pentyl 4¿- cyanobiphenyl (5CB) and it is doped with 4-pentyl 4¿-...

The aim is to determine the amount of absorbtion of the one component of a mixture at the nemtic/air interface using neutron reflection. The host material in the mixture will be...

Gene (nucleic acid) delivery to the cytosol or nucleus of a cell is, without the aid of a suitable delivery system, an inefficient process. Here the interaction of a defined...
