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

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...

Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the...

We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition...

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...

Liquid crystal displays are ubiquitous but they are not perfect. It is desirable to reduce the voltage required to switch a pixel from light to dark in order to reduce power...

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 debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron...

Polymeric stabilisers are often used in the preparation of emulsions and dispersions of particles. The purpose of this additive is to help keep the mixture stable so that it can...

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...

Lubrication by saliva is a key factor in oral health and food consumption. It is know that salivary lubrication is mediated by the thin proteinaceous film i.e., the pellicle,...

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...

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

In the context of a project in collaboration with ISIS that focuses on structural studies under mechanical confinement, with a specific focus on biological lubricants, 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...

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...

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...

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...

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...

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...
