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... -
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... -
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... -
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... -
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... -
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... -
Interfacial Structure of Colloidal Dispersions - the air/latex interface
Adsorption of colloidal particles to an interface is of fundamental interest in understanding wetting, capillarity and colloidal forces as well as being of practical importance... -
Effect of Concentration Charge and Ionic Strength on Adsorption of Small Part...
Despite the wide practical interest in particulate colloids there have been few studies that exploit the advantages of reflection and neutron scattering to study adsorption of... -
Adsorption of sodium polyacrylate to sapphire - how does a colloidal stabiliz...
Stabilizers of colloidal particles are often complex and their function may involve several mechanisms to impart stability of a wide range of conditions. Sodium polyacrylate is... -
Adsorption of perfluoroalkyl substances to solid soil interface to elucidate ...
Perfluoroalkyl substances (PFASs) are stable compounds and commercially desirable. They are widely used, for example, as surfactants in textile and paper products and in aqueous...
