Investigation of glycolide-h4 and d4 at high pressure.
This proposal seeks to investigate the polymorphism and polymerisation of glycolide. Glycolide is a six-memebered ring structure that polymerises into poly(glycolic acid) and is... -
Crystal Lattice Distortions associated with a Frustrated Spin System in Trian...
In this proposal, we propose the high-resolution neutron diffraction experiments for AFeO2 (A=Cu and Ag) using HRPD. Although CuFeO2 is well known as one of magneto-electric... -
Spray-coating plastic solar cells: New materials & innovative processes for O...
We propose to study a range of new selenium containing lower energy gap organic photovoltaic materials deposited by spray coating using neutron reflectivity. The new materials... -
Antibiotic Interactions with models of the Gram negative bacterial outer memb...
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
Radiation induced hydrogen abstraction - A combined X-ray and neutron diffrac...
X-ray induced radiation damage drastically limits the structural information accessible in diffraction experiments from macromolecules at 3rd generation synchrotrons. Relatively... -
High pressure structural study of BaD2
Simple hydrides are of scientific interest due to their suitability for storage of hydrogen in the solid state. These materials also display a wealth of interesting physics,... -
Polymorphism and polymerisation of methacrylic acid
This proposal seeks to explore the polymorphism and polymerisation of methacrylic acid using high pressure. We have recently studied acrylic acid at high pressure using single... -
Conduction Pathways in Alkali Lanthanide Pyrosilicates, A3LnSi2O7
Alkali Lanthanide Pyrosilicates (general formula = A3LnSi2O7) are promising candidates for use as solid electrolytes in all solid state Li-ion and Na-ion batteries. To date the... -
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... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
Identifying the muon site in fluorine containing compounds
Fluorides form model systems with which we can test ideas about muon sites. We therefore propose a series of short experiments on well-defined fluoride systems that will be... -
The Structure of Alkaline Earth Germanate Glasses
We request GEM beamtime to study the structure of a series of calcium germanate glasses. The changes in coordination number and properties which occur in alkali germanate... -
Interaction of Chiral Amino Acids with Hydrated Vermiculite Clay
The aim of this proposal is to obtain an atomistic understanding of the adsorption of chiral amino acids on mineral surfaces. Our previous experiments on LOQ and at ILL on D16... -
In-situ Hydrogenation of Calcium Nitride
Nitrides of alkali and alkaline earth metals are an interesting set of materials specifically for their potential in reversible hydrogen storage. However, many fundamental... -
Influence of nanoparticle size and morphology on the relative proportions of ...
Palladium is able to dissociative absorb large quantities of hydrogen, reversibly. However, the formation and relative proportion of different phases of palladium hydride, and... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -
A Structural Study of Tungsten Tellurite Glasses
Tungsten Tellurites are being used to make optical fibres that transmit light into the mid infra red. However, not much is know about the structure of these glasses. We wish to... -
Quantum dynamics in a J_eff=1/2 isotropic triangular-lattice antiferromagnet
This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum antiferromagnets. A canonical model system is the spin-1/2 triangular...
