Tuning cycloidal ordering by epitaxial strain in BiFeO3 thin films
Owing to their promising applications, especially in spintronics, multiferroics have been at the fprefront of condensed matter research for a number of years. In these... -
An off-specular neutron scattering study of the 'peristaltic mode' in the dew...
We plan to use the OFFSPEC SPIN-Echo reflectometer to study the mechanism of the 'peristaltic mode' in the spinodal dewetting of thin polymer films. In the peristaltic mode the... -
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... -
Correlations between local magnetism and spin-orbit transport physics in topo...
One of the main challenges in spintronics research is to provide a link between magnetic elements and conventional electronic circuits. A novel approach to this old problem is... -
Hydrogen kinetics in nano-layered metal hydrides for hydrogen sensing applica...
Accurate, safe and cheap hydrogen detectors functioning under a wide range of conditions are a vital ingredient for using hydrogen as an energy carrier. A novel, safe and cheap... -
pH Responsive Polymer Blend Surfaces
Polymers, end-functionalised with carboxylic acid (COOH) groups do not normally segregate to film surfaces due to the high surface energy of these functionalities. However, we... -
pH-Responsive Polyelectrolyte Brushes Studied by Neutron Reflectivity and in ...
pH-responsive polymer brushes comprise of long polymer chains of either a weak acid or base chemically attached to a surface. Depending upon the degree of ionisation along the... -
Phase separation in confined block-copolymers on a structured substrate studi...
Co-polymers confined in small droplets may have a structure different from that in the bulk. These droplets are produced by annealing a spin-coated polymer film with a thickness... -
Micelle curvature effects on polyelectrolyte-surfactant film structures
This proposal continues our investigations into polyelectrolyte-surfactant thin films which form at the air-solution interface. Our previous work investigated structure... -
Understanding anaesthetics: Ethanol partitioning into lipid membranes, effect...
Ethanol plays an important role in the human metabolism. It is in particular known to act as a drug enhancer by increasing trans-membrane permeability, and as an anesthetic.... -

PNR determination of magnetic interface states and exchange coupling in hybri...
The atomic interfaces between ferromagnetically ordered thin films with perpendicular anisotropy and either films with magnetically ordered in-plane anisotropy or a non-magnetic... -
Charged nanogels and their ability to penetrate model lipid membranes
Drug delivery through the skin is an important route for administration of therapeutic agents. However, the outermost layer of the skin, the stratum corneum provides a... -
Adsorption and activity of Thermomyces lanuginosus Lipase (TLL) at the oilwat...
The purpose with the proposed project is to provide a better understanding of structural changes in interfacial lipid layers due action of lipolytic enzymes. In this study we... -
Inducing Magnetic Order in Topological Insulators by Ferromagnetic Insulators
We intend to study a new class of materials known as 3D topological insulators. The electronic states in these materials have a non-trivial topology, different to almost all... -
Adsorption of an Anionic Surfactant on Anionic Surfaces in the Presence of Ca...
In this proposal we request beamtime on the Inter reflectometer to study the unexpected adsorption behaviour of the surfactant bis(2-ethylhexyl) sulfosuccinate caesium salt... -
Modification of an adsorbed cationic layer by anionic surfactants below the CMC
In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic... -
calcite water interface
The interface of CaCO3 (calcite) and water is of paramount importance in a number of key academic and industrial areas, including scale deposition in domestic and industrial... -
Depth profiling fullerene-free organic solar cell blends using neutron reflec...
In Sheffield, 9% efficient organic solar cells have been made using a new non-fullerene acceptor called ITIC, when blended with semiconducting polymers. GIWAXS measurements have... -
Effect of calcium ions and ionic strength on model bilayer structure
Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we...
