For polymer vesicles to act as effective molecular delivery systems we must efficiently encapsulate a molecular payload within the vesicle. We would like to use neutron... -
Liquid phase self-assembly of semiconductor nanoparticles for photon multipliers
Our research aims to develop plastic films that change the colour of the light that passes through them, not by absorbing certain wavelengths of light, as a simple colour filter... -
Does spinodal dewetting proceed by peristalsis?
We shall demonstrate the use of neutron reflectometry to obtain three-dimensional structures in a non-invasive experiment. Spinodal dewetting is one of the few areas where... -
Interfacial structure in self-assembling conjugated polymer photovoltaic devices
The proposal aims to determine the degree of interfacial mixing and roughness at an interface between two conjugated polymers, as part of a broder program to understand how to... -
Phase retrieval for non-trivial systems
Neutron reflectometry (NR) is a very powerful technique for the study of thin layers. It is able to measure composition, thickness and roughness and is a very penetrating... -

We have recently demonstrated, using small angle neutron scattering in combination with other techniques, that in organic photovoltaic devices (OPVs) the additive... -
Polymer brush profiles using off-specular reflection from the walls of trenches
Nature frequently uses charged, weak-polyelectrolyte brushes at interfaces to control surface function and properties; surface wetting, lubrication, to limit deposition of... -

We propose to study a range of new lower energy gap organic photovoltaic (OPV) materials deposited by spray coating using neutron reflectivity. The new materials to be studied... -
Ligand conformation at semiconductor nanoparticle surfaces for high-efficienc...
The efficiency of silicon solar cells is limited to 29%. One possible way of breaking this limit uses a process called singlet fission, converting a high energy photon into two... -
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... -
