Molecular Weight and Incipient Crystallinity Effects on Polymer Surface Segre...
We have established multi-end functional polymers as potent additives for spontaneous surface modification of blends. Since semi-crystalline polymers such as PE, PP, PET could... -
Interfacial adsorption of keratin as characterised by neutron reflection
This proposal constitutes part of our ongoing study towards understanding the adsorption of keratins and their interactions with ionic surfactants at the solid/water interface.... -
Assembly of functionalized nanoparticles at fluid interfaces
To try to understand the variation in surface tension as a function of functionalized gold nanoparticle particle and SDS concentration, we will make measurements of the specular... -
Depth profiling the composition of multilayer organic solar cell thin films
We propose to study thin-film blends of the polymer:fullerene system PTB7:PC70BM using neutron reflectivity (NR). This system currently exhibits the highest power conversion... -
Surface Smectic Layers in difluoroterphenyls
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... -
Conjugated polymer-small molecule interfaces for photovoltaic applications
Organic materials offer a range of low-cost options for large area fabrication of solar (photovoltaic) cells. Unfortunately, organic photovoltaics suffer from low efficiencies.... -

We wish to make specular NR measurements on fluorophore functionalization of amine-functionalized polypyrrole (PPy-NH2) films. The critical issue is film penetration of solution... -
Understanding Phospho-L-Serine (PS) role in the Organization of Cholesterol C...
Our goal is to understand the role of POPS, a lipid component only found in the inner leaflet of plasma membrane, in the organization of cholesterol in cell membranes. Our... -
Investigating the response of lipid bilayers to physically structured substrates
The functionality of biological membranes is closely tied to their structural behavior. To understand this behavior we propose to study the conformality of artificial lipid... -
Using SERGIS, SESANS and NR to probe nanoscale cavities created within templa...
Nanoporous membranes fabricated by polymerization around soluble templates have found many applications in (bio)sensors, charge storage devices, filtration and catalysis.... -
