Aggregation phenomena inside polymer brushes: lateral structure
We will use off-specular reflectivity to probe the characteristic lateral length-scales in responsive polyelectrolyte brushes grown by surface-initiated ATRP from solid-liquid... -
Kinetics of surfactant multilayer formation / dissolution at interfaces
The formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures has been recently reported, and... -
Competetive adsorption in hydrophobin / protein mixtures at the air-solution ...
Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self assemble at interfaces and in solution. This... -
Multilayer formation at the air-water interface in polyamine / surfactant mix...
The spontaneous formation of multilayer structures at interfaces by surfactant self-assembly is emerging as an important and more common structural signature associated with a... -
Competitive adsorption in hydrophobin / protein mixtures at the solid-solutio...
Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self-assemble at interfaces and in solution. This... -
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... -
Neutron Reflection Studies on Adsorption of Myristoyl-L-Carnitine at the Air/...
The acyl-L-carnitines are a group of novel surfactants. Following our recent home laboratory work to synthesize, purify and characterize them, the aim of this proposal is to... -
How polymer functionality influences multilayer formation at the interface in...
Spontaneous multilayer formation at interfaces from surfactant self assembly is emerging as an important structural signature associated with a wide range of potential... -
Interactions between a mixture containing two cationic polyelectrolytes and a...
Recently there has been a vast expansion in understanding about the interactions between oppositely charged polyelectrolyte/surfactant mixtures. The use of neutron reflectometry... -
Using polymer / surfactant mixtures to optimise / enhance perfume delivery to...
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
Surface adsorption of lipopeptides: interfacial layer structure
Lipopeptide surfactants are highly effective at reducing interfacial tension. However, there is a general lack of understanding of the relationship between their molecular... -
Lipopolysaccharide Functions as Bacterial Receptors to Antimicrobial Peptides
Neutron reflection (NR) is well established for studying molecular films such as lipid monolayers. Its high depth resolution combined with deuterium labelling can determine the... -
Solution Aggregation of Short Peptide Amphiphiles
Short peptide sequences consisting of hydrophobic and hydrophilic amino acid units are capable of self-assembly, leading interfacial adsorption and solution nano-aggregation.... -
Interactions between a polymer brush grown from a macro-initiator-modified sa...
We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator... -
Adsorption of modified PEI / SDS mixtures at the solid-solution interface
Polymer-surfactant mixtures are extensively used in a wide range of domestic, industrial and technological applications. This proposal is part of a collaboration between Oxford... -
Spontaneous surfactant multilayer formation at interfaces induced by multival...
The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is now emerging as an important structural signature associated with a wide range...
