Understanding pressure-driven structural changes in FePO4-II
The room temperature high pressure behaviour of FePO4-I has been investigated and a phase transition at around 2.5 GPa to the orthorhombic phase (FePO4-II) accompanied by a... -
Competitive interactions in polymer-particle-surfactant blends
Many formulations comprise distinct chemical species that exhibit antagonistic or synergistic interactions that result in unpredictable behaviour. Previous work from our group... -
pH Responsive Polymer Blend Surfaces
Polymers, end-functionalised with carboxylic acid (COOH) groups do not normally segregate to film surfaces due to the high surface energy of these functionalities. However, we... -
Probing chiral interactions in aqueous amino acid deriving polymers
Sodium deoxycholate (NaDC) is a low molecular weight gelator, widely known as one of the components of bile salts. Above a specific concentration, NaDC is able to form pH... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
Low Temperature Ordering in ZrMn2+xD3 Superstochiometric Deuterides
ZrMn2H3 is a Laves Phase intermetallic hydride with interesting materials properties - unlike most Laves Phases, the parent alloy ZrMn2 is not a line phase but has a wide range... -
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... -
A high pressure diffraction study of the formation of symmetric hydrogen bond...
The imidazole ring is important in both biologically important molecules and materials chemistry. That imidazole derivatives can function in such diverse roles is due in part to... -
Alloxan - a high density organic under pressure
Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application... -
Novel gels with supercritical carbon dioxide
This proposal is to probe the gel structure with High Pressure SANS (HP-SANS) using an in-line pressure cell. The ability to control the properties of supercritical CO2,... -
Impact of Elasticity on Surface Wetting
We have recently characterised a surface wetting transition for a low molecular weight oligomer in a high molecular weight rubbery polymer. Although weak surface segregation of... -
High Pressure Neutron Diffraction of Croconic Acid
Croconic acid (Cacid) possesses a well-defined hysteresis in polarization at room temp and the highest spontaneous polarization observed in organic ferroelectrics to date. The... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Non-uniform elastic deformation of layered crystal structures
The aim of the experiment is to determine the relative compressibility of the structural layers in three 211 MAX phases (Ti2AlC, Ta2AlC and Cr2AlC) using the PEARL-HiPr beam... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
A High-Pressure investigation on 3,4,5-Trinitropyrazole
This proposal will explore the effect of elevated pressure on the 3,4,5-Trinitropyrazole (TNP). TNP releases a large amount of dinitrogen gas as a detonation product which is... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our... -
Packing structural conformation of (H/D) nanogels at the air/water interface
The interfacial behaviour of thermoresponsive N-propylacrylamide (NPAM) based nanogels differs from solid nanoparticles because of the soft structural character. These nanogels...
