Measuring strains in geologically important hydrous minerals
We request 4 days of beam-time on ENGIN-X to measure the elastic behaviour of polycrystalline samples of gypsum, antigorite, and talc as a function of uniaxial load. All three... -
The influence of texture on mechanical twinning in calcite
We request 3 days of beam-time on ENGIN-X to investigate the influence of lattice preferred orientation on the onset of mechanical twinning in polycrystalline calcite (CaCO3)... -
Proton ordering and hydrogen bonding in the hydrous zinc phosphate hopeite, Z...
We request 4 days of beamtime on SXD in order to locate the protons and quantify their ordering within the structure of hopeite Zn3(PO4)2.4H2O. Hopeite is an important phase in... -
Low Temperature Magnetic, Thermoelastic and Structural Behaviour of Antiferro...
We propose to study the low temperature structural and magnetic changes in three clinopyroxene phases FeGeO3, CaNiSi2O6 and CaCoSi2O6. All three phases order... -
The effect of redox on the substitution mechanism of Ti in meteoritic hibonite
We request 3 days of beam-time on HRPD to identify the substitution mechanism of Ti3+ and Ti4+ in synthetic hibonites [CaAl12O19]. The experiment forms part of a larger... -
Exploring the potential of neutron diffraction methods for examining the mech...
We request 2 days of beamtime on ENGIN-X to obtain neutron diffraction data as a function of uniaxial load on two different shale gas mudstones. Both the multiphase character... -
Does elastic twinning play a role in the thermal expansion behaviour of polyc...
We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger... -
Effect of grain size on stress partitioning within plastically deforming two ...
We request 4 days of beamtime on ENGIN-X to measure the influence of relative grain size on stress partitioning between the constituent phases in two phase polycrystalline... -
Measuring strains in low-symmetry, crystal-chemically complex, hydrous minerals
We request 4 days of beam-time on ENGIN-X to measure the development of elastic strains in geologically important minerals as a function of uniaxial load. We wish to perform... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite.... -
