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... -
Does tethered PEG behave as a typical polymer brush at the solid-liquid inter...
We propose to make neutron reflectivity measurements of hydrophillic polymers covalently attached, via thiol chemistry, to the gold-water interface. In particular, we will... -
Quantifying the adsorption of lecithin on sucrose particles to understand cho...
Small angle neutron scattering will be used to directly quantify the adsorption of lecithin at the interface between partially deuterated sucrose particles contrast-matched to a... -
Kinetics and growth mode of aggregation phenomena inside polymer brushes
We will use time-resolved specular neutron reflectivity measurements to follow the in-situ growth of polymer brushes by surface-initiated ATRP. This will enable us to determine... -
Assembly of functionalized nanoparticles at fluid interfaces
To try to understand the variation in surface tension as a function of functionalized gold nanoparticle particle and SDS concentration, we will make measurements of the specular... -
Realistic bacterial membrane mimetics to understand antimicrobial activity & ...
We will use neutron reflectivity measurements of lipopolysaccharide (LPS) layers at the air-water interface to help develop a realistic mimetic for the periphery of bacteria... -
Structure and formation kinetics of insulin aggregates
We will use time-resolved SANS measurements to follow the self-assembly kinetics of insulin from protein monomers to fibrils. By measuring through a well-defined lag phase we... -
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... -
Responsive polymer brushes grafted from gold nanoparticles: interaction with ...
We will use SANS to characterize dispersions of gold nanoparticles functionalized with poly(dimethyl aminoethyl methacrylate) brushes grafted from 25 nm gold nanoparticle...
