Relation between surface tension and adsorbed amount of proteins at the air/w...
The surface tension of proteins often exhibits a reproducible lagtime, which is sensitiv to a range of conditions such as concentration, pH, ionic strength. We have also found... -
Surfactant mixing at hydrophilic solid/liquid interfaces: (A) air/water measu...
The overall objective is to model the amount and composition of adsorbed mixtures of three types of zwitterionic surfactant and two charged surfactants at the silica/water... -
Stabilization of anisotropic pigment particles: Reflectivity
We wish to determine the effect of various stabilisers on anisotropic pigment particles that are being developed for use in liquid crystal composites. We will investigate the... -
Cation site disorder in KTiOPO4 isostructures
KTiOPO4 (KTP) is a well known non-linear optical material. Its crystal structure has highly asymmetric Ti-O bonds, a rigid TiO6-PO4 lattice and K cations trapped in cages. The... -
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... -
The use of surfactant structure to control self-assembly induced by the addit...
This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at... -
Interaction of a cationic surfactant with rigid oligoanions
The interaction of small polyelectrolytes or oligoions with surfactants appears to follow a model that we have recently established for large polyelectrolytes but the smaller... -
Neutron Reflectivity Study of NeutrAvidin Immobilised onto Ti Implant Surfaces
We ask for 3 days of beam time on Inter/SURF to study the adsorption and adlayer characteristics of avidin on Ti surfaces, relevant for biomedical applications, such as... -
Adsorption maxima at the solid/liquid interface
Adsorption maxima have been reported for adsorption at the hydrophilic solid/water interface based on measurements on powders and solution analysis. Many would claim that this... -
Variable Temperature studies of an anomalous proton sponge benzoic acid co-cr...
As part of a long-running programme, we have identified many co-crystallisation systems producing hydrogen-bonded molecular complexes yielding fascinating X-ray diffraction and... -
Impact of multivalent counterions on surfactant self-assembly
We request SANS beam time on LOQ to study the impact of multivalent counterions on the micellisation of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /... -
Surface adsorption in hydrophobin and hydrophobin / surfactant mixtures
Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interfaces. Their unique film forming... -
Polymer-surfactant adsorption at the oil-water interface
Polymer-surfactant stabilised emulsion droplets are a potentially exciting route for micro-encapsulation of volatile agents (such as perfumes, flavours and many other benefit... -
