We have developed and demonstrated a novel process to overcome chemical reaction equilibrium constraints on an important reversible industrial chemical reaction by using... -
Hydrothermal synthesis and calcination of hydrotalcites
Hydrotalcites are anionic clays which have a variety of applications, including use as environmentally friendly catalysts and catalyst precursors. In this experiment we propose... -
Total scattering from multiferroic bismuth ferrite at high temperatures
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... -
Does The Crystal Structure of Leucite Evolve with Temperature to the Proposed...
The concept of an aristotype, or equivalently, the basic structure, that represents the highest symmetry crystal structure that can be attained, either experimentally, or... -
Locating transition metals in the apatite structure
Apatites are currently of major interest in a number of fields: biomaterials, solid oxide fuel cells, catalysis, environmental remediation to name a few. Hydroxyapatite -... -
Dipolar frustration on the triangular lattice: Order and disorder in AgNCO
We propose to use neutron total scattering to characterise isocyanate (NCO-) orientations within the orientationally-disordered phase of AgNCO. The arrangement of NCO- ions in... -
Local structure and oxygen nonstoichiometry in the cubic Ba0.5Sr0.5Co0.8Fe0.2...
Oxygen nonstoichiometry (d) of perovskite-type Ba0.5Sr0.5Co0.8Fe0.2O3-d (BSCF) was recently studied by combination of TGA, coulometric titration and neutron diffraction (ND).... -
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... -
A Total Scattering Study of Local Structure in BIMEVOXes
The BIMEVOXes are an important family of fast oxide ion conducting solids that exhibit very high conductivities at low and intermediate temperatures. A study of local ordering... -
