Hydrogen-bond dynamics of water in C-S-H, the binding phase of Portland cement
During the setting process of Portland cement, different mineral hydrates nucleate and grow, of which calcium silicate hydrate (C-S-H) is the most important binding phase. It is... -
Determining the Crystal and Magnetic Structures of [Li(oxalate)]2[Co5(OH)8]
Dense corrdination frameworks that contain inorganic centres connected into extended lattices by polyatomic anions often adopt highly anisotropic structures. Thus they often... -
Understanding the formation of diamonds: Calibrating the coesite solid-inclus...
Diamonds provide our only direct samples of the very deep Earth and understanding their origin is consequently of great interest to Earth Scientists. The origin of diamonds can... -
The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -
High-resolution phonon spectra of silicon nitride phases
Silicon nitride is a mechanically tough and light-weight ceramic material able to withstand high temperatures. It is therefore becoming increasingly attractive for use in... -
Hydrogen Uptake by Pillared Graphite Oxides
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
What is the Room Temperature Structure of NaTaO3?
The current proposal seeks to establish the origin of t non-perovskite-like peak splitting observed in HRPD data for NaTaO3. It is our hypothesis that this is a result of the... -

Polycarbonate and tetramethyl bisphenol A polycarbonate
The miscibility of polycarbonates (PC) with polystyrene (PS) appears to be closely related to chain dynamics. Among all polycarbonates, tetramethyl bisphenol-A polycarbonate... -
The effect of redox on the substitution mechanism of Ti in meteoritic hibonite
We request 3 days of beam-time on HRPD to identify the substitution mechanism of Ti3+ and Ti4+ in synthetic hibonites [CaAl12O19]. The experiment forms part of a larger... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Molecular and framework dynamics in CH3NH3PbCl3
We propose to use MARI to measure the molecular and framework dynamics in CH3NH3PbCl3 which has become of interest in the context of efficient photovoltaics. CH3NH3PbCl3 is... -
QENS studies of molecular hydrogen in K-doped electrospun graphite nanofibres
The physisorptive capability of graphite-based nanomaterials for hydrogen is strongly dependent on their surface areas and nanomorphologies. We have made electrospun graphite... -
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... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Nuclear Dynamics in Methylammonium Lead Iodide, One Atom at a Time
Methylammonium lead iodide is currently one of the most promising materials for solar energy applications, with light-conversion efficiencies exceeding 20%. Although insightful,... -
Proton/deuteron mobility in ammonium hexachlorometallates.
The piloting experiments RB820478, RB610497 and RB 10067 on VESUVIO on (NH4)2PdCl6 and (NH4)2TeCl6 have shown that: (i) at 300 K, the dynamics of NH4+ and PdCl6- and TeCl6- is... -
Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -
