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... -
INELASTIC NEUTRON SCATTERING STUDY OF THE CRYSTALLINE ELECTRIC FIELD OF CeNi9...
A current hot topic in correlated electron physics is the magnetic phase diagram resulting from competing Kondo and RKKY interactions with magnetic frustration. One interesting... -
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... -
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... -
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... -
vibrational spectroscopy of a novel dipalladium(I) hydride displaying dynamic...
Our report of a novel cationic dipalladium(I) hydride in (Angew. Chem. Int. Ed. 2010, 49, 6315) shows a linear Pd-Pd-H core with H-ligand dynamics (solution NMR). Ab-initio MD... -
Single crystal diffraction study of magneto-electric Er2BaNiO5
Er2BaNiO5 has been reported recently as a magneto-electric material, displaying a spontaneous polarization at T=55K, followed by a transition to a collinear antiferromagnetic... -
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... -
Structures and magnetism of chemical and electrochemical deintercalates of la...
We propose to use POLARIS to perform two related experiments. Firstly we will investigate the structures and compositions of derivatives of some layered Mn/Cu oxysulfides which... -
Determination of the magnetic field-temperature phase diagram in metal-organi...
Metal-organic magnets are of interest primarily due to the synthetic versatility enabled by the vast array of organic complexes which can be used to coordinate magnetic ions and... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -
Spin excitations in La2CoO4
We will use MAPS to measure the complete spin excitation spectrum of the quasi-two-dimensional S=3/2 antiferromagnet La2CoO4. The measurement is motivated by recent observations... -
Determination of the on-top vibrational mode of the surface hydride in PdH.
Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the... -
Understanding the mechanism of benzyl alcohol oxidation using supported Au-Pd...
This proposal is a continuation of RB1000003. The aim of the present experiment is to gain further insight into the mechanism of benzyl alcohol oxidation using supported Au-Pd... -
Framework flexibility and host-guest hydrogen bonding in the metal-organic do...
The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the... -

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...
