Investigating dental resin polymer structures of as a function of light-curin...
Dimethacrylate resins are currently used for dental fillings. The polymers are set by free radical polymerisation. At present light curing protocols require 40s exposure at... -
SESANS of beetle scales and butterfly wings
Neutron scattering and in particular SESANS is able to give us excellent ensemble averaging of the optical properties of materials which exhibit structural colour. We plan to... -
Mercury sulphide dimorphism in liquids and glasses
A waste majority of crystals exists in several polymorphic forms in different domains of the P,T-diagram. Liquids and glasses also exhibit polyamorphism and the question remains... -
Co-surfactancy of oil-soluble and water-soluble surfactants in emulsion stabi...
The structures of emulsions formed from mixed oil-soluble and water-soluble amphiphiles (respectively derivatives of polyisobutylene, PIBSA, and polyacrylamide, PAM) will be... -
Do hydrotropes stabilize, or destabilize, micelles?
The aim is to investigate and understand interactions of hydrotropes (primitive amphiphiles) with a new range of industrially important non-ionic surfactants, alkyl-capped... -
Impact of multivalent counterions on surfactant self-assembly
We request SANS beam time on LOQ to study the impact of multivalent counterions on the micellisation of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /... -
Multiscale time resolving study of the crystallisation of polyethylene from s...
This experiment is focused on the use of the unique capability of Nimrod to study the crystallisation of polymers from solution. We wish to obtain high quality time-resolved... -
The effect of anionic lipid unsaturation on the interaction with cytochrome c
While peripheral membrane protein-lipid interactions were originally considered to be solely electrostatic in nature, it is now accepted that they encompass more complicated,... -
SANS studies of imprinted nanogels: evaluation of a possible relationship bet...
The aim of the project is to use Small Angle Neutron Scattering (SANS) to determine the particle sizes and the internal shell dimensions of the nanogels as a function of the... -
Solution structures of the immunologically important proteins IgG and C3b
IgG antibody represents one-third of new drugs currently in development. We will unravel the solution structures of the Fab and Fc fragments within IgG. Following our earlier... -
Understanding elevated temperature and creep properties of a novel maraging s...
Producing a steel alloy that has both high and low temperature capabilities is non-trivial. However, recently a novel maraging steel has been developed that has shown excellent... -
Early stages of amyloid aggregate formation
We will study the kinetics of the early stages of aggregate formation in protein solutions under conditions that are known to result in the formation of amyloid protein fibres... -
Atomic structure of 2NaY-Ga2S3 (Y = Cl, Br, I) liquids
Alkali halide sulphide and selenide glasses MY-Ga2X3-GeX2 (M = Li, Na, Rb, Cs; Y = Cl, Br, I; X = S, Se) are promising hosts for active and passive optical devices, solid-state... -
Co-micellization of hydrotropes and surfactants
This proposal builds on recent work with hydrotropes alone (Langmuir, 2011, 27, 12346-12353); now co-micellisation of hydrotropes with surfactants will be investigated. The aim... -
Study of self-organization of cationic pH- and thermo responsive copolymers w...
The aim of our work is to study structural properties of supra-molecular assemblies formed in aqueous solutions of cationic pH- and thermo-sensitive block-gradient copolymers... -

Controlled release from lipid-alkylglycoside vesicles, as triggered by amylas...
The consumer demands for functional food have increased the interest for encapsulation of bioactive compounds in the food industry. Encapsulation is crucial, since these... -
Interaction of polypeptides with surfactants: aqueous solution aggregation
This proposal constitutes part of our ongoing study towards understanding how collagen based polypeptides interact with ionic surfactants using SANS. Both SDS and C12TAB will be... -
Multiscale time-resolving study of solid state crystallisation from the mesom...
We will exploit the unique capability of Nimrod in the study of the long standing issue of polymer crystallisation. We focus on isotactic polypropylene which has been quenched... -
Exchange kinetics of complex coacervates core micelles
Coacervates have been studied for a long time for their unusual properties: they are dense networks of charged polymers that are soluble in water. Instead of flocculating when...
