The aim of this experiment is to study the nucleation and molecular layer-by-layer growth of a 'thin film' (TF) phase at the buried substrate interface of thin films of fully... -
Structural phase diagram of hydrated silks
The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich... -
Sub-micron structure of conjugated polymer interfaces
There are two contributions to the rms roughness of a polymer-polymer interface; i) the so-called ¿intrinsic interfacial width¿ due to mixing of the polymers at a molecular... -
Reflectometry studies of the mechanism of formation of mesoporous silicate fi...
Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from... -
Structure formation in catanionic surfactant/polymer templated inorganic film...
Recently we have been investigating the mineralization of polymer-surfactant films to create thicker and more robust self-supporting membranes. Our previous experiments used the... -
Intermediate q-range study of Fe35Ag65 and Fe15Ag85 thin films
We intend to explore the intermediate q-range (0.1 to 50\AA-1) in nanogranular Fe35Ag65 and Fe15Ag85 thin films. These systems have been proven to have a crossover between a... -
Magnetic nanostructures of Fe-Ag and Fe-Au granular thin films
Nanogranular thin films of FexM100-x (M=Au,Ag; x=7,20,39) are an excellent system to study the magnetism of nanoparticles in diamagnetic matrices coupled by direct, RKKY and... -
Polarised neutron reflectometry of functional BiFeO3 thin films
Multiferroic materials are a rare case where ferromagnetism and ferroelectricity coexist. Bismuth Ferrite (BiFeO3) is of special interest as both properties order at room... -

A method to weigh polymer films and adsorbates during neutron reflectivity me...
With the advent of TS-II, there is a drive to probe more complex and multicomponent systems using neutron reflectivity. In such studies, confidence associated with model Nb fits... -
The origin of room temperature ferromagnetism in strained BiFeMnO epitaxial f...
We have produced high quality, epitaxial and phase pure thin films of BiFe0.5Mn0.5O3 (BFMO) grown on (001) SrTiO3 substrates using pulsed laser deposition. The magnetic... -
Investigation of zwitterionic surfactant templated bio-polymer films as senso...
We have found it possible to deposit mesostructured surfactant templated polymer thin films on solid substrates. To date the majority of work has used hexadecyltrimethylammonium... -
Amide monolayers at the polymer melt air interface
This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are... -
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....
