Molecular Collapse and Conformation of Low Molecular Mass Polyacrylic Acid an...
There is conflicting information about properties of polycrylic acid and its behaviour in aqueous solution. This proposal for an investigation by SANS that is directed at... -
Conformation changes in aqueous medium of a water treatment protein from Mori...
Major technological and scientific challenges arise from the pressure to provide widely available and sustainable technologies for the societal requirements for health and a... -
Adsorption of cationic surfactants to Al2O3
A recent experiment has provided clear evidence for a large maximum in the adsorption just below the critical micelle concentration of the surfactant hexadecyl trimethyl... -
Understanding the decrease in adsorption of surfactants at a solid surface ab...
Previous data obtained from neutron reflection shown in Figure 1 has clearly shown that the surface excess of some surfactants when adsorbed from aqueous solution to a sapphire... -
Interfacial properties of a lung protein after exposure to gas-phase ozone
Lung surfactant protein B, SP-B, is found at the air-water interface of the lung. A deficiency in SP-B at birth is known to be fatal. We have recently successfully studied the... -
Latex - structure in binary mixtures - studies of crystallisation and stability
Recent experiments on SANS2D have indicated that small colloidal particles can act as macroions that screen the charged interactions of larger particles. This can cause changes... -
Structure of Colloidal Crystals Near a Solid Surface
The structure of colloidal crystals (dispersions of particles that spontaneously order in a regular array) is known to be influenced by solid boundaries. However there are few... -
Gas-phase oxidation of insoluble monolayer at air-water interface with no equ...
The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects cloud droplet size and optical properties, important climatic... -
Structure of AOT layers at the sapphire water interface ¿ avoiding an isotope...
Several interesting results have emerged in studies of Aerosol-OT at the sapphire/solution interface that relate to effects of counter-ions, insensitivity to pH as well as the... -
DPPC bilayer oxidation by aqueous singlet oxygen
The oxidation of membrane lipids by reactive Oxygen Species, ROS, is implicated in cell apoptosis, cancer and ageing. We have performed preliminary experiments studying the... -
The interaction of oxidatively damaged lung proteins with anionic lipids
Lung surfactant protein B, SP-B, interacts with lipids at the air-water interface of the lung where its presence is vital for correct respiratory function. SP-B and its... -
Organisation of Latex Particles in Solution and at the Water/Sapphire Interface
Polystyrene latex represents an excellent model system for studies of the physical properties of colloidal particles. The materials can be prepared with controlled size, and... -
Order in the bulk and at the surface of dispersions of colloidal particles
Highly ordered dispersions of charged polymer particles that are tens or hundreds of nanometres diameter can be prepared. These are useful model systems for self-assembly and... -
Polystyrene latex - 'single crystal' structure studies and melting under flow
For deionised, charge stabilised latices, there has been some uncertainty about the stacking sequence of close packed layers in samples at equilibrium. The ABCA stacking in... -
Does ozone initiate damage to the main pulmonary surfactant lipid, DPPC, or c...
Exposure to ozone gas can cause inflammation of the airways and breathing difficulties. The initial reaction of ozone is thought to be predominantly with lipids present in the... -
Adsorption of proteins from Moringa seeds at the air/solution interface
Proteins from Moringa trees have attracted considerable interest as flocculents for water purification and possibly as materials for remediation of contaminated soil.... -
Binary colloidal mixtures - SANS contrast variation to study high concentrati...
Mixtures of colloidal particles of essentially two different sizes are commonly used in technological applications such as film formation on surfaces, paper coatings, etc.... -
Adsorption of concentrated Aerosol-OT to Sapphire ¿ the effect of divalent sa...
AOT is also known to be very sensitive to the concentration and nature of counter-ions. When adding a sufficient amount of divalent salt to an AOT solution, a very strong Bragg... -
Penetration and reaction of hydroxyl radical into organic films at the air-wa...
The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important climatic effects.... -
DPPC bilayer oxidation by aqueous singlet oxygen
Oxidation of membrane lipids by Reactive Oxygen Species, ROS, in cells may impact ageing, cell apoptosis and cancer. We propose to use our skills obtained studying the oxidation...
