Aggregation of chiral catalysts based on the Trost ligand
The project represents a new application of SANS to investigate chemically sophisticated chiral catalysts, addressing important questions in modern synthetic and catalytic... -
Mixed micelles with "green" surfactants
This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard surfactant mixtures have been extensively studied... -
Dispersed lamellar phases in dense CO2
This proposal aims to explore these dispersed lamellar phases with a variety of F7H4 derivatives,to help understand their formation in supercritical CO2 (sc-CO2). The focus is... -
Is there a CMC for surfactants in non-aqueous solvents?
The aim of this project is to use SANS to determine if a critical micelle concentration (CMC) exists for the formation of inverse micelles in non-polar solvents. The CMC is a... -
Studies of the mechanism of hydrotropy
The objective is to refine current understanding about the mechanism of hydrotropy with respect to polarity and electrostatic character of hydrotropes and hydrophobic solutes... -
Surfactant aggregation in magnetic ionic liquids
This proposal aims to explore aggregation behavior of common surfactants in magnetic ionic liquids (MILs) and to investigate the effect of a magnetic field on aggregate size,... -
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... -
Photo-reactive surfactants for nanoparticle generation
The aim is to employ contrast variation CV-SANS to investigate structure in novel systems used to generate metal-containing nanoparticles on organic solvents by UV irradiation.... -
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... -
Microemulsions stabilized by magnetic surfactants
Surfactant systems responsive to pH, temperature, CO2, and light are known. Our new work has shown for the first time, magneto-responsive surfactants (also being ionic liquids... -
Magnetic self-aggregating ionic liquids (MSAILs)
This proposal is to explore aqueous phase structures with a new class of magnetic self-aggregating ionic liquids (MSAILs) (see Figures 2 and 3 below). The dilute micellar... -
Adsorption of magnetic surfactants
Surfactants responsive to pH, temperature, CO2, and light are known, however, our recent work has shown, for the first time surfactants that are magneto-responsive, and also... -
Adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfac...
This proposal is to explore adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfactant anions (see Figure 1) at the air-water interface, as a function of...
