Optimizing surfactants for CO2
This experiment addresses an important, and still unresolved, question in the field CO2-philic surfactants: what is the minimum fluorine content necessary to obtain a CO2-philic... -
Structural distortions and partial order in the selenate and chromate analogu...
The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an... -
Magnetoelectric coupling in the multiferroic ceramic BiFeO3 - PbTiO3
The polycrystalline ceramic BiFeO3 - PbTiO3 is both ferroelectric and antiferromagnetic for a wide range of compositional space. We have shown in previous experiments that (1)... -
Structure and Phase Transitions of XNbOP2O7, with X = ND4 and Rb
In this proposal we request 3 days of beam time on HRPD to study the structure and phase transitions of XNbOP2O7 (X = Rb and ND4). These materials have been shown to undergo... -
In Situ High Pressure NMR study of the Direct Synthesis of NaAlH4
NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a... -
Correlation of structural parameters with electrocaloric performance in (Ba,S...
Kay objectives: measurements of Ti-O bond lengths and Ti-O-Ti angles in a series of (Ba,Sr,Ca)TiO3 perovskites and correlate with the observed variation of Tcs of the FE-PE... -
Molecular Mechanisms of Enhanced Thermal Conductivity in Copper-based Nanofluids
The combination of the transport properties of liquids with the high thermal conductivity of metals is a promising way of improving heat transfer efficiency and thus reduce... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
The structure of ammonia borane in ammonia and THF
In this proposal we aim to understand the solvation of AB by two of the most important solvents ? ammonia and THF. Neutron diffraction is a key technique in this context because... -
Crystal Lattice Distortions associated with a Frustrated Spin System in Trian...
In this proposal, we propose the high-resolution neutron diffraction experiments for AFeO2 (A=Cu and Ag) using HRPD. Although CuFeO2 is well known as one of magneto-electric... -
Low temperature, high pressure phase transition of the Improper Ferroelectric...
We have found that the 134-perovskite, HgMn7O12 (HgAMnA3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both... -
Structure and properties of ammonium-doped water ice
The ammonium anion is comparatively soluble in ice and may also increase the solubility of associated cations that would otherwise not be easily accommodated in the crystal... -
Thermal expansion of persubstituited aromatics I: benzene.
Benzene is probably the most studied compound in the history of organic chemistry. Whenever a new experimental technique or theoretical method is being developed most of the... -
Continued studies of the high temperature structural behaviour of Ca2Mn3O8
We recently synthesised a new layered manganes oxide with a frustrated connectivity of Mn4+ ions. Variable temperature studies demonstrated a deviation from linearity at... -

Thermal expansion of persubstituited aromatics I: benzene.
Benzene is probably the most studied compound in the history of organic chemistry. Whenever a new experimental technique or theoretical method is being developed most of the... -
Spontaneous strain and framework distortion in hybrid Prussian blue analogues
The metal-organic Prussian blue analogues (HIm)2K[M(CN)6], where HIm is the imidazolium cation and M = Fe or Co, have switchable dielectric constants, since the imidazolium ions... -
High Pressure Thermoelastic Properties of Thermoelectric PbSe
We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste... -
Kinetics of the ordering transition in ice Ih; crystal structure and thermal ...
Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of...
