Structural determination of non-stoichiomentric phases Li2+yND for 0<y<1
In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of... -
QENS studies of hydride ion diffusion in alkaline earth hydrides
We propose to study hydride ion diffusion in AEH2 (AE = Ca and Ba) using the QENS technique. We have recently demonstrated that the charge carrier in these materials are hydride... -
Oxide ion vacancy distribution in A site substituted defect pyrochlores.
Electrolytes based on pyrochlores such as Ln2M2O7 (M = Ti, Zr, Hf) have attracted attention due to their relative stability combined with relatively high ionic conductivity at... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
Investigation of the Li-intercalation mechanism for the perovskite Li0.18Sr0....
Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to... -
In-situ studies of alkaline earth nitride deuterides
Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical... -

In situ NPD investigation of double perovskite manganites in wet hydrogen atm...
The aim of the experiment is to investigate by means of in situ NPD the structural behavior of two new Mn-rich double perovskites compounds, NdBaCo1.5Mn0.5O5+d and NdBaMn2O5+d... -
Copy of: Search for density and diffusivity water-like anomalies in a ionic melt
Many network-forming liquids exhibit water-like thermodynamic and kinetic anomalies, the most obvious of which concerns the presence of a regime of anomalous densities as well... -
Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Investigation of the phase transition in La2Mo2O9 from structural and conduct...
There has been significant interest in the oxide ion conducting material La2Mo2O9 as a new electrolyte after initial reports of conductivity as high as that of YSZ at lower... -
Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
Local structure in layered perovskite oxides - probing ion transport in fuel ...
Layered oxides are increasingly attractive as electrode materials in energy technology applications, such as fuel cells, electrolysers and permeation membranes. As the... -
Order-Disorder Transitions in Layered Tellurides
We have prepared a new series of layered tellurides Cr2-xInxGe2Te6, containing 2D ordered arrays of (Cr,In) cations and (Ge-Ge) pairs. Recent neutron measurements reveal indium... -
Oxygen mobility in the defect perovskite Sr3SbO5.5
We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the... -
Magnetic Structure and Martensite Twin-Laws of ferromagnetic Co2-Ni-Ga and Fe...
Pseudoelastic, ferromagnetic Co2NiGa type high-temperature shape memory alloys (HT-SMAs) are characterized by a wide range of tunable transformation temperatures and lower... -
In-situ conductivity study of double perovskites for use as potential anode m...
It is a challenge to develop materials for use in fuel cell applications. Presently we are preparing new perovskite and double perovskite structured compounds being potential... -
Fluorophosphate Derivatives of Gypsum and Lithium in Biogenic Manganese Oxides
This proposal seeks neutron diffraction beamtime to study two important systems. We have demonstrated that monofluorophosphate (PO3F) can be substituted into gypsum (CaSO4.2H2O)... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...
