Understanding the structure of sunscreen formulations: where does the active ...
The negative effects of exposure to ultraviolet rays, 290-400 nm, are well known. Long exposures to these rays often cause skin damage (e.g. skin burns, melanoma). Topical... -
Molecular Collapse and Conformation of Low Molecular Mass Polyacrylic Acid an...
There is conflicting information about properties of polycrylic acid and its behaviour in aqueous solution. This proposal for an investigation by SANS that is directed at... -
Probing the structure of polymeric foams on SANS2d ?
Polyurethane foams (PUFs) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agent... -
Solubilisation Dynamics in Microemulsion Systems
The dynamic aspects of solubilisation of oils into surfactant systems, often forming microemulsions, are only little known so far, despite their importance for optimising... -
Surfactant ionic liquids as tuneable structured media
This proposal aims to explore aqueous phase structures of a new range of ionic liquid surfactants (IL-surfs). These IL-surfs have interesting potential applications as reaction... -
How do demulsifiers work? A SANS study of model oil-water interfaces.
The project is to understand fundamental structure-performance relationships of chemical demulsifiers in water-in-crude oil (w/o) systems. In particular, to understand how... -
Simultaneous SANS and modulated SESANS studies of cross-linking in cellulose ...
Recently we have trialled the new techniques enabled on Larmor which permit simultaneous measurements of nanoscale and macroscale structure. These experiments gave new insights... -
Nonfluorous Cosurfactant/Hyperbranched Surfactant Mixtures for W/CO2 Microemu...
This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2... -
Polystrene chain conformations in good solvents and electrospun fibres
This proposal is centered on the preparation of nanoscale fibres prepared by electrospinning and is the focus of the final year PhD programme of Saeed Mohan. These experiments... -
Investigating Mesoporosity in Hierarchical Aluminophosphates
Optimising catalyst lifetime and performance is pivotal to enhancing the sustainability of industrial catalytic processes, allowing greater product yields, at lower... -

Dynamics of chain exchange between stiff complex coarcervate core micelles (C...
Complex coacervates core micelles (C3Ms) are colloids obtained through the co-assembly of neutral-ionic copolymers bearing oppositely charged functional groups. These micelles... -
Opening up microemulsion phases in CO2
New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have... -
Concentration of small acids using complex coacervates
Volatile fatty acids (VFAs) are widely used chemicals, which serve as precursors for e.g., polymers. These VFAs can be produced through unsustainable petrochemical routes.... -
