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... -
interaction of a pharmaceutical water-soluble polymer with bio-relevant surfa...
We have been developing hydroxypropylmethyl cellulose (HPMC) microspheres for delivering poorly water-soluble drugs. The in vitro dissolution data showed that the presence of... -
Linking the solid state and solution thorium aqua structures: A solid state p...
A understanding of the aqueous chemistry of the actinide ions is not as well developed as for transition metals or the lanthanides. Fundamentally important information such as... -
Recovery and characterisation of high-pressure phases in the systems H2O ¿ NH...
The objective of this experiment is to characterise four particular high-pressure polymorphs of various hydrates discovered by us in recent years during work carried out using... -
Neutron diffraction of amorphous calcium sulfate
Amorphous calcium sulfate (ACS) is transitory phase in the precipitation of calcium sulfate minerals such as gypsum. ACS is also be present in mineral systems which may be... -
Reflectometry studies of the mechanism of formation of mesoporous silicate fi...
Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from... -
Short range order in ferroelectric deuterated triglycine sulphate
We want to better understand the structural modifications and short-range correlations in ferroelectric triglycine sulphate near the ferroelectric phase transition. Above the... -
Neutron diffraction of amorphous iron sulfates (AFS)
Amorphous iron sulfate pentahydrate has been identified as one of the iron sulfates found on the Martian surface during the Spirit and Opportunity Rover missions in recent... -
SANS studies of Amphotec (aggregates of amphotericin-cholesteryl sulfate)
The anti-fungal agent amphotericin B (AmB) can be administered to patients in aqueous solution complexed with cholesteryl sulfate (CS), and this formulation helps to minimise... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding... -
Thermoelastic properties and high-pressure decomposition of MgSO4.11D2O (synt...
The undecahydrate of magnesium sulfate (meridianiite) is likely to occur a major rock-forming mineral in the interiors of large icy satellites such as Ganymede, Callisto and... -
Structural phase diagram of rare earth substituted multiferroic BiFeO3 - revi...
BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
Short range order in triglycine sulphate above the phase transition temperature
We want to better understand the intermolecular interactions in deuterated triglycine sulphate (DTGS). DTGS is a hydrogen bonded ferroelectric with a second-order, order... -
Thermal expansion and phase transition in magnesium sulfate trihydrate
A recent single-crystal study determined the crystal structure of MgSO4.3D2O, and discovered that a first-order phase transition occurs when the crystal is cooled below 245 K....
