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... -
A study on atomic clustering in Fe-Cr alloys by NIMROD diffractometer
Low temperature embrittlement of stainless steels are due to phase separation and it is known that the kinetics of phase separation depend on the initial structure. However, the... -
Understanding the effect of compaction forming on the structure and performan...
A vast amount of work has been conducted on understanding metal organic frameworks (MOFs) in their powder form. However, for use in industrial processes, powders will need to be... -
Variable temperature studies of x = 0.10, 0.25, 0.50 and 0.75, Bi1-xNaxFe1-xN...
Multiferroic materials exhibiting at least two ferroic orders are the subject of extensive research due to many potential technological applications. Bismuth ferrite (BFO) is by... -
Improper ferroelectricity in hexagonal tungsten bronzes

Hydrogen production from ammonia using lithium imide: an isotope study
We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -

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... -
Spatial, Chemical, and Temporal Resolution of Platinum-Catalysed Benzene Conv...
This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the... -
Investigation of pore filling via pseudo-condensation of supercritical hydrog...
This proposal aims to use NIMROD to glean information on the mechanisms of pore filling and to obtain a quantitative absolute value for the density of supercritical hydrogen... -
Investigation of the low temperature phases of SrSnO3
The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low... -
Formation of hard carbon from carbonized biowaste and in situ neutron study
hard carbon are promising anodes for sodium ion batteries, due to their high capacity and green production from biowaste. However, they require treatment at very high... -
