SANS DETERMINATION OF CO2 ABSORPTION INTO SURFACTANT STABILISING LAYERS
Recent SAXS measurements have indicated that CO2 can dramatically swell the surfactant layer in w/o microemulsions formed in CO2-swollen oils and also enhance solubilisation... -
Development of internal strains during compression of Al-Si alloy Al-7Si-0.4Mg
This proposal follows on from our successful experiment on ENGIN-X lin 2006, where we measured the development of strains in the aluminium and silicon phases of a common casting... -
Anomalous elasticity in negative thermal expansion materials
Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk... -
Structure, incompressibility and thermal expansion of ammonia dihydrate II
The structure and properties of the high-pressure phase of ammonia dihydrate, ADH-II, have been challenging to determine. However, the structure has been solved recently by... -
Thermal expansion studies of metallic glasses showing magnetocaloric effect
The main aim of our proposal is investigation of thermally induced volume changes occurring in short range order of amorphous pseudo-binary Fe(Mn)-B alloys in the vicinity of... -
The effect of pressure and temperature on mode-softening in negative thermal ...
We have done extensive structural and computational studies on the recently discovered phenomenon of negative thermal expansion (NTE) in metal-organic framework (MOF) materials,... -
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... -
Thermal expansion and simultaneous Raman spectroscopy of methanol ammoniates,...
We have recently determined the structures of methanol-monoammoniate, and Me-hemiammoniate from neutron powder data. These are found to have different degrees of C-H...O... -
Crystal structure and thermal expansion of acetylene (C2D2)
Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Low temperarature structure of Sr2CoO2Cu1.85S2
This proposal aims to exploit the superior flux on the upgraded HRPD coupled with the intrinsic high resolution to examine the differences between a sample of Sr2CoO2Cu1.85S2... -
The crystal structure and thermal expansion of orthorhombic NiSi
NiSi is a technologically important material that is also of interest to Earth Scientists because of the possible role of Ni and Si in the Earth¿s core. It crystallises in the... -
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.... -
Thermal expansion and phase transition in magnesium sulfate trihydrate
A recent single-crystal study determined the crystal structure of MgSO4.3D2O, and discovered that a first-order phase transition occurs when the crystal is cooled below 245 K....
