The high temperature high pressure behaviour of ammonia hydrates
Ammonia hydrates are important constituents of the outer solar system. In recent x-ray studies we have found evidence for a solid solution between ice and ammonia at high... -
Investigating the internal structure of thermally annealed two-component poly...
The elucidation of the compositional profile of polymer:small molecule nanoparticle films is critical for applications such as water processable organic solar cells. In order to... -
In-situ high resolution neutron diffraction studies of cemented carbides
Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in... -
Neutron Total Scattering of Crystalline Materials in the Gigapascal Regime
Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure.... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
High-pressure powder neutron diffraction study in Pd2MnIn
Intermetallic ternary full Heuslers have potential spintronic applications, due to a possible link between the mechanisms for magnetism and half-metallicity in these systems.... -
In-situ Neutron Diffraction Studies of Lithium Battery Materials
This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have... -

In-situ studies of alkaline earth nitride deuterides
Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical... -
Micelle structures in unequal mixtures of amino-acid surfactants
In a previous proposal we started to study the micellar structures formed from biodegradable surfactants synthesised using amino acids as the headgroups. The aim of this work is... -
Structures of metastable water ice XVII with different guests molecules
Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice... -
Structural determination of non-stoichiomentric phases Li2+yND for 0<y<1
In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of... -
Wetting Transitions of Tackifiers in Adhesives
Migration and surface segregation of low molecular weight oligomers in adhesive formulations is a poorly understood, but hugely important phenomenon, responsible for most of the... -
