Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
Oxygen mobility in the defect perovskite Sr3SbO5.5
We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the... -
Simultaneous Conductivity-Diffraction Studies of Halide Superionics
We request 5 days beamtime on the Polaris diffractometer to perform simultaneous ionic conductivity and neutron powder diffraction measurements of five superionic binary... -
Local structure within Li+ depleted LiFePO4
Lithium iron phosphate is a commonly used cathode material in Li-ion batteries. The material exhibits a two phase system on lithiation and delithiation with narrow solid... -
Characterisation of superalloys strengthened by Co3Ti
One method by which the efficiency of gas turbine engines may be improved is by increasing the gas stream temperature on entry to the turbine. Currently this temperature is... -
Local Structure within Fluorite-Pyrochlore Solid Solutions
This proposal requests 6 days beamtime on the Polaris diffractometer to study the nature of the local structure within two systems which have been reported to show a solid...
