Solvent-induced curvature of micelles
The purpose is to follow a structural evolution as water soluble (normal curvature) micelles are gradually transformed into oil soluble (reversed curvature) aggregates. Although... -
Spin relaxation of short-lived spin-labelled radicals in solution
The spin relaxation rates of free radicals in solution can provide valuable information about the dynamics of molecular tumbling in solution, and solvent-radical interactions.... -
Solvation of cellulose-derivate polyelectrolyte in mixed solvents and added s...
Carboxymethylcellulose (NaCMC) is the most widely used cellulose derivative; it forms an anionic, water-soluble, polyelectrolyte with vast applications in the food,... -
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... -
Elemental Boron synthesized in supercritical metallic solvents at high pressu...
Our recent high (P,T) developments at PEARL beamline will allow us to study the kinetic and thermodynamic behavior of boron 11B under pressures up to 12 GPa and temperatures up... -
Microscopic structure of acetic acid in water and methanol
Some of the most important chemical reactions involve Brønsted acids and bases where the solvation structure and transport dynamics of charged defects in hydrogen-bonded... -
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... -
Close control over microemulsion stability using blended solvents
The aim of this proposal is to investigate a novel approach to phase separation in microemulsions using careful choice of organic solvents, and appropriate mixtures.... -
Change in conformation of a chiral poly(2-oxazoline) induced by temperature o...
The aim of this experiment is to investigate the change in conformation of a chiral polymer dissolved in hexafluoroisopropanol as the temperature of the system is varied.... -
Mesostructured titania films from ethanolic solutions
In this proposal we wish to continue our current work on mesostructured inorganic films in largely ethanolic solutions, containing limited amounts of water. Transition metal... -
The structure of aprotic and aromatic solvents
In this proposal we would like to study the structure of polar aprotic and aromatic liquids using H/D and 15N/*N isotopic labelling on SANDALS. The molecules chosen for study... -
Probing the products of free radical reactions in ionic liquids
Many room temperature ionic liquids (salts with melting points near room temperature that hereafter will be referred to as ionic liquids) are ¿green solvents¿ for chemical... -
Mechanism of charging metal oxide colloids in non-polar solvents
Contrast-variation SANS (CV SANS) will be used to determine how surfactant inverse micelles interact with model metal oxide colloids. By using deuterated surfactant (D-AOT) with...
