Competitive interactions in polymer-particle-surfactant blends
Many formulations comprise distinct chemical species that exhibit antagonistic or synergistic interactions that result in unpredictable behaviour. Previous work from our group... -
Probing chiral interactions in aqueous amino acid deriving polymers
Sodium deoxycholate (NaDC) is a low molecular weight gelator, widely known as one of the components of bile salts. Above a specific concentration, NaDC is able to form pH... -
Kinetic Study of the Mechanistic Complexation Process Between DNA and Cationi...
We propose to use the new SANS2d to study the dynamic structural evolution in the couse of the formation of DNA-cationic polymer complexes. The dynamic process and the mixing... -
Designing polymer therapeutics to diffuse through mucin
Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key... -
On the peculiarities of the structure of particle stabilised foam
Many formulated products pass through or end up as foams, comprising immiscible millimeter sized bubbles dispersed into an aqueous continuous phase. Frequently, surfactants or... -
Encapsulation of hydrophobic species into cat-anionic micelles in polymer sol...
This proposal continues our investigations into film forming polyelectrolyte-surfactant solutions. We have found that mixed cat-anionic micelle systems offer greater control... -
Generation of 3D-networks by mixing inexpensive HC-polymers, amphiphiles, and...
For the last two decades, many polymers have been tested to increase CO2 viscosity for enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional HC-polymers were... -
Probing the viability of water-in-CO2 microemulsions with Headgroup-free amph...
Recent SANS studies of an unusual headgroup-free surfactant (Nohead FC6-HC4) produced data that implied the formation of W/CO2 microemulsions (MEs) at a particular pressure (P)... -
The structure of nanographene and nanographite intercalates in solution
We aim use SANS to study in situ structure of solutions of uncharged and charged graphene formed by dissolving graphite and graphite intercalation compounds. We wish to compare... -
Exploring CO2-philic/ CO2-phobic amphiphiles, cross-linkers and HC-polymers f...
Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional... -
In-Situ Neutron Diffraction Study of Plastic Deformation and Crack-Growth Mec...
Our continuous proposal work will focus mainly on the influence of dislocation dominated deformation modes on fatigue-crack-growth in order to fully complete our proposed... -
CO2 foams stabilized by W/CO2 interfacially active hydrocarbon surfactants an...
CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles... -
W/CO2 nanodispersions as an energy-saving nanoreactor separable by pressure a...
Recent studies implied an unusual headgroup (HG)-free, fluorocarbon (FC) surfactant Nohead FC6-HC4 to form stable, W/CO2 nanodispersions (W/C NDs). With the unusual surfactant... -
The Effect of Polydispersity on the Self Assembly of Diblock Copolymers
Block copolymers are of interest due to their ability to undergo microphase separation. Originally block copolymers were produced with a low polydispersity index (PDI) as they... -
Heterogeneous hydrogenation in continuous flow followed by NMR and total neut...
It has been estimated that 80-90 % of chemical processes use catalysis in at least one step of the production process. Their use increases the energy efficiency of the process... -
Structure determination of gelled cellulose nanowhisker assemblies
We have developed a new and benign method for the production of cellulose based aerogels, highly porous materials with applications in insulation, drug delivery, gas storage,... -
Self assembly of thermoresponsive gels
Thermoresponsive gels are widely used for tissue engineering and drug delivery applications. They consist of a thermoresponsive polymer that self-assembles in a 3D network when...
