Structure, thermal expansion and vibrational properties of ammonium bicarbona...
Ammonium carbonates, sensu lato, have relevance to carbon capture schemes and as potential hydrogen storage materials. These compounds occur on Earth as minerals and, since... -
Spin excitations in La2O2Fe2OSe2 ¿ A Mott insulator candidate
We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to... -
Phase Separation in NaTaO3. Can it be controlled by pressure?
The present proposal seeks to establish the pressure dependence of the Pbnm-Cmcm transition in NaTaO3 and some doped variants thereof. It aims to understand the understand the... -
Investigations of amorphous pharmaceutical materials produced from different ...
Pharmaceuticals are usually formulated in the crystalline state for obvious reasons of stability. They may also exist in a disordered and less cohesive state i.e. amorphous... -
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... -
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... -
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... -
Combined neutron and X-ray single-crystal diffraction studies of selected 2-p...
Hydrozones and their metal complexes exhibit subtle redistribution of electron density as a function of substitution, type of the metal center and intermolecular interactions.... -
Quasielastic Neutron Spectroscopy of Ammonium Borohydride
We ask for 7 days on IRIS to study the quasielastic scattering in ammonium borohydride (NH4BH4). Using enriched ND4 and BD4, we aim to separate out the difference rotational and... -
Magnetic ordering and an extraordinary anomalous Hall effect in the itinerant...
-Fe3Sn2 is a rare example of a ferromagnetic metal. It features a giant Anomalous Hall Effect (AHE) at room temperature that makes it a candidate material for spintronics... -
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... -
Characterisation of the low temperature phase transition in Pb(CD3COO)2 .3D...
We propose to use high resolution neutron powder diffraction for the study of the nuclear structure of Pb(CD3COO)2.3D2O in its low-temperature phase and to characterise with... -
H/D isotope effect on enamtiomers: the case of Alanine
In the current description of any molecular system based on the Schrodinger equation with a Hamiltonian accounting only for the electromagnetic forces, the structural properties... -
Structural studies of the cycling and decomposition of Mg(NH3)6(BH4)2
Given its high hydrogen gravimetric density, ammonia may be utilised as a hydrogen carrier, and thus ammonia stores are an area of interest. It is known that Mg(BH4)2 takes up... -
Structure-property relation in integer-spin quantum magnets
Our objective is to determine how changes in symmetry affect the magnetic ground state of spin-1 magnets. Low-dimensional S=1 systems are believed to support rich phase diagrams... -
Configurational and displacive disorder in the cubic NTE material Cd(CN)2
Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8. This... -

Completing the Magnetic Ordering-Crystal Structure Phase Diagram of Supercond...
The key objective is to measure three samples of composition Fe(1.05)Te, Fe(1.12)Te, and Fe(1.14)Te as a function of temperature (base to 80 K) through their magnetic ordering... -
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... -
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...
