The First Structural Characterisation of some Gallium Oxide Polymorphs
We propose to make the first detailed structural study of some polymorphs of gallium oxide that remain poorly characterised and yet have applications in catalysis and are used... -
Structure of Lead Germanate Glasses
We wish to perform a detailed and comprehensive study of the structure of lead germanate glasses, over a wide range in composition. Most structural studies of germanate glasses... -
An analysis of British Iron Age coins from the Hallaton hoard
The aim of this experiment is to analyse the composition and texture of a number of coins from the North Eastern series of Roman coins that form part of the Hallaton hoard.... -
Structural Phase Transition with a Large Volume Change in (Bi,Nd)FeO3
BiFeO3 attracts considerable attention because of its multiferroic and ferroelectric properties. Nd-substitutions in antiferromagnetic BiFeO3 induce a significant ferromagnetic... -
Investigating the local structure of sodium within Bioglass®.
Bioactive glasses are of considerable interest due to their potential for biomedical applications. In order to model the behaviour and dissolution of these materials it is... -
Study of the reaction mehanism for carbon-based FeF3 nanocomposites as cathod...
Metal fluoride materials, through the use nanocomposites, recently appear as potential candidates as next generation high energy density positive electrodes for Li-ion... -
Structural studies of bioactive yttrium doped alumino-silicate glasses.
Yttrium doped glasses are of considerable interest due to their potential for use as in-vivo radioactive beta- emitters for localised treatment of liver cancer and other... -
Structure-Property Relationships in Polymorphs of Mn(CN)2
We will determine the atomic and magnetic structure of two polymorphs of manganese cyanide, Mn(CN)2, which exhibit negative thermal expansion (NTE). The two forms are related;... -
A structural study of titanium tellurite glasses
Tellurite glasses exhibit strong non-linear properties which are related to the asymmetric environment of the Te atom. The non-linear optical effects are strongest when the Te... -
Evaluation of inelasticity effects in diffraction
For total diffraction measurements using neutrons it is important to correct the data for inelasticity effects, especially for samples containing light atoms. Conventionally... -
Isotopic Mass Contrast Study of Silica Glass
We wish to perform neutron diffraction measurements on glass samples of SiO2 and 30CaO.70SiO2 containing both natural oxygen and 18O. The oxygen scattering lengths are almost... -
Structural studies of modified iron phosphate glasses to understand key struc...
We intend to use neutron diffraction and x-ray diffraction to investigate the structure of potassium and barium iron phosphate glasses, which are potential candidate systems for... -
Structure-Property Relationships in Photoluminescent Platinum and Palladium C...
The average and local structure in the mixed-metal cyanides, Ni1/2Pt1/2(CN)2, Ni1/2Pd1/2(CN)2 and Pd1/2Pt1/2(CN)2 will be determined to give the M-C and M-N bond lengths, the... -
Texture memory and variant selection for steel and titanium and zirconium alloys
The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with... -
Structural Models of the Polymorphs of Gallium Oxide
Gallium oxide is an apparently simple oxide that has been reported to exist as at least 5 polymorphs all of which are stable at room temperature. Structural models, however, for... -
Magnetic structures of antiferromagnetic heavy fermion CeAuAl3 and CeCuAl3 co...
CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of... -
Structural and Magnetic Characterizations of the New, High Pressure Synthesiz...
After an almost forty year lull in research on multiferroic materials, there has been a resurgence of interest in them. However, it is particularly challenging to synthesize a... -
Metastable phase formation and memory effects in barium borate glasses.
BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates... -
'Stabbing' or 'cut & thrust'? Texture analysis to distinguish usage of Bronze...
Defining when the practical use of Bronze Age swords changed from stabbing to cut-and-thrust weapons would have a huge impact on Bronze Age research. The change was accompanied...
