Considerable research has been devoted to materials to fulfil the roles of electrodes and electrolyte within SOFCs, with focus on the fluorite or perovskite crystal structures....

In order to reduce the greenhouse effect, research on fuel cells and particularly on SOFCs has been extensively developed as the only produced waste is water. In situ structural...

Ti2AlN and Ti4AlN3 are MAX phases that exhibit a unique combination of the characteristics of both ceramics and metals coupled with an unusual combination of mechanical,...

Sr0.75Y0.25CoO2.62 is a promising cathode material for solid oxide fuel cells. It shows metallic behaviour above 600K and molecular dynamics simulations have concluded that...

Lithium iron phosphate is a commonly used cathode material in Li-ion batteries. The material exhibits a two phase system on lithiation and delithiation with narrow solid...

Microwave techniques are of interest to the materials chemistry community as they allow access to new metastable materials, and offer synthetic routes that are considerably...

Acceptor-doped perovskite oxides exhibit significant proton conductivity under humid or hydrogen containing atmosphere, which opens a unique possibility to be used as...

The proposal consists of two parts. Firstly, we will undertake an ambient temperature ex-situ PND study of some new ternary transition metal carbide phases that have been...

Lithium ternary nitrides are emerging as promising candidates in several applications. They are currently a key focus in the search for improved anode materials in lithium ion...

We request 5 days beamtime on the Polaris diffractometer to perform simultaneous ionic conductivity and neutron powder diffraction measurements of five superionic binary...

We have prepared a new non-stoichiometric series Cr2-xInxGe2Te6. X-ray diffraction data can be indexed on the rhombohedral unit cell of the end-member (x=0) phase. This adopts a...

We propose an experiment on POLARIS to elucidate the changing structure and stoichiometry of mixed metal quaternary molybdenum nitrides, Con(1-x)FenxMonN (n=3, 6; 0 ≤ x...

We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger...

A recent experiment (RB820171) unexpectedly revealed that a sample of beta-Mo2N exhibited a number of extra reflections at 4 K; a temperature below the superconducting critical...

The topotactic reduction of Sr3Co2O5Cl2 and Sr3Co2O5.80 yields the Co(II) phases Sr3Co2O4Cl2 and Sr3Co2O5 respectively. These phases contain corner linked arrays of...

We will probe the response of the 18K superconductor LiFeAa to pressures of up to 2 GPa in order to investigate the evolution of the crystal structure. In particular we wish to...

There has been recent interest in the use of cermets based on stabilised delta bismuth oxide based solid electrolytes as cathodes in solid oxide fuel cells. It has been shown...

KTiOPO4 (KTP) is a well known non-linear optical material. Its crystal structure has highly asymmetric Ti-O bonds, a rigid TiO6-PO4 lattice and K cations trapped in cages. The...

Significant research has been given towards synthesis and characterisation of electrolyte materials with high proton conductivity for intermediate temperature range (200-600°C)...

This proposal requests three days on the Polaris diffractometer to investigate the nature of local structure in the well known proton conducting perovskite system...
