Total scattering study of the orientational phase transition in para-terphenyl
There is currently a resurgence of interest in phase transitions in orientationally disordered molecular crystals. This is partly driven by the fact that new experimental and... -
Origins of flexibility in a zero-thermal-expansion framework
Our proposal is to use neutron total scattering on GEM to study framework flexibility and the phenomenology of the displacive phase transition in the cyanide-containing... -
Total scattering study of the garnet-phase battery electrolyte Li7La3Zr2O12
The cubic garnet-phase of Li7La3Zr2O12 is one of the most promising new electrolytes for use in an all-solid-state battery. We are proposing a total scattering experiment on... -

Structural changes of PdRu alloy nanoparticles caused by catalytic reactions
We are proposing 4 days of beamtime on GEM/Polaris to conduct the neutron powder diffraction experiments on PdRu alloy nanoparticles supported on CZ (CeO2-ZrO2) before and after... -
Mixed alkali environment in chalcohalide glasses for optical applications
Heavy alkali halide sulphide and selenide glasses are promising hosts for active and passive optical devices. Lithium and sodium chalcohalide glasses exhibit high ionic... -
Cation environments in lead-free glasses
BaO+ZnO containing glasses are being studied as an alternative to lead-based glasses because they exhibit excellent dielectric, thermal, optical and crystallisation properties.... -
Structure of SnO-P2O5 glasses doped with heavy metal oxides
The exchange of Pb by Sn in high-refractive index and low temperature process glasses is a common need in pollution control. Here it is planned to study the structure of binary... -
Total scattering from multiferroic bismuth ferrite
Bismuth Ferrite (BiFeO3) is the archetypal multiferroic material and as such has been copiously studied using a wide variety of techniques. Despite this, new structural and... -
Atomic structure of ternary tin phosphate glasses
Tin phosphate glasses are the alternative as lead-free glasses with zero photoeleastic constant (PEC) for fibers that are used in sensors of electric current. Since the binary... -
The role of Bi in magnetic and structural dimerization of Ba3BiRu2O9.
The aim of the present proposal is to use total scattering to investigate changes in the local structure of Ba3BiRu2O9. This compound undergoes an unusual magnetovolume... -
Structures of New Oxides from Total Scattering
Our objective is to determine accurate structural models for some novel oxide materials that we have recently prepared using new synthesis approaches, each of which is formed as... -
Local structure in defect fluorite disordered Er2Zr2O7 and pyrochlore ordered...
Cubic A2B2O7 oxides with A standing for a rare-earth element and B for a transition or main block metal have been systematically studied for their frequently exotic... -
Cation environment and the tellurite anomaly
We have recently shown that the anomalous behaviour of the Te-O coordination number, nTeO, for binary tellurite glasses is related to the presence of terminal Te=O bonds in... -
Disorder in substituted beta-tricalcium phosphate for waste immobilisation
We have a long established interest in the materials used for the immobilisation of nuclear waste from the domestic power industry and legacy waste from various defence... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Modifer Interactions in Ternary Tellurite Glasses
We wish to better understand the interaction between alkali and alkaline earth modifiers within the tellurite glass network by measuring neutron correlation functions, T(r)s,... -
Understanding the local structure of Li6PS5X (X = Cl, Br, I) and its impact o...
Cubic Argyrodites, Li6PS5X, are promising candidates for solid state electrolytes and much effort is put in understanding their structure property relation. NMR studies... -
Structural behaviour of zinc in low phosphate content glasses for bone cements
Bone cements are an important class of biomaterial used in hard tissue surgery as well as periodontology. Many of these are glass-ionomer cements formed from an aluminosilicate... -
Dynamical disorder or incipient nano-ferroic distortions in CaSnO3 perovskite?
It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....
