Probing the interaction of hydrogen with supported gold nanoparticles
Small gold nanoparticles (1-5 nm) supported on metal oxides are extremely active catalysts for C-C coupling, aerobic oxidations and selective hydrogenations. The interaction of... -
Hydrogen-bond dynamics of water in C-A-S-H: insights into the hydration prope...
The manufacture of every ton of cement emits approximately 0.8 tons of CO2 into the atmosphere, comprising 5-7% of the global human-made CO2 emissions. A low pH - low CO2 class... -
Local structure / electronic-structure relationships in functional materials
This proposal is a low-cost/high-gain first step in an ambitious project: namely, to develop a combined neutron scattering and electronic structure calculation approach as a... -
Impact of Jahn-Teller Distortions in Sr0.5Pr0.5MnO3
We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and... -
Interlayer and Interparticle Water in Clays
Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for... -
Neutron Diffraction Study of a Spin-1/2 Pyrochlore Lu2Mo2O5N2
Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have... -
collective dynamics and structural heterogeneity in an ionic liquid
We propose to investigate the high frequency dynamics of ionic liquid (IL), 1octyl-3-methylimidazolium chloride ([C8MIM]Cl) deuterated by means of Inelastic Neutron Scattering... -
Understanding negative compressibility in KMn[Ag(CN)2]3
Negative linear compressibility (NLC) is the phenomenon whereby at least one of the linear dimensions of a material actually expand under hydrostatic pressure. It is only... -
Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
Crystal and Magnetic Structures of Ba2BTeO6 (B=Cu, Ni, Zn)
Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9... -
In-situ High Temperature Studies of BiFeO3 in a Stabilising Oxygen Atmosphere
The drive to find novel materials for applications such as data storage has led to a resurgence in research into multiferroic materials. Bismuth ferrite is the most widely... -
Competition between C-H---O hydrogen bonds and C=O----Br halogen bonds
Our main objective in this proposal is to study the competition between halogen and hydrogen bonding as a function of temperature in the complex (CH3)2C=O--- Br2. The results of... -
Dynamics studies of water and ice in carbon nanohorns
Recent diffraction [GEM] and DINS [Vesuvio] studies of water in carbon nanohorns have suggested that there is substantial proton delocalisation along the H-bond between... -

Polymorphism of phenytoin at low temperature
Phenytoin is a simple organic pharmaceutical material that exhibits a phase transition at low temperature to a new phase. The high temperature form exhibits some unusual... -
Stochastic vs. Intermolecular Motions in Strongly Associated Liquids: The Cas...
Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic... -
Understanding the effects of pressure and temperature on the structure of an ...
The discovery of superconductivity in iron-pnictide materials has generated much excitement in the past year about possibly unifying mechanisms for high-temperature... -
