We propose to study the phase diagram of a lead-free piezoelectric material consisting of a tricritical triple point where anomalous enhancement of the physical properties have...

Relaxor ferroelectrics are a class of locally disordered crystals possessing peculiar structure and electrical properties. The solid solution of a relaxor perovskite and PbTiO3...

The accurate determination of the defect structure of rare earth (RE) doped ceria solid electrolytes is fundamental for the comprehension of oxygen diffusion and charge...

BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates...

Perovskites are used in many applications such as electrode materials in fuel cells or as catalysts e.g. in syngas conversion, CO oxidation, N2O decomposition, or...

Vanadium based compounds have attracted considerable interest as positive electrode materials for Li ion batteries. This is due to vanadium’s ability to display a range of...

This is a proposal to establish the structural and chemical differences between two phases of composition very close to CaFe3O5 which have been shown by other authors [Hong, K....

White rust (WR) is a highly reactive material that acts as a precursor in many chemical processes. It is produced during iron corrosion and has been implicated as a key reactive...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

Ge-(Ga,Sb)-S glasses are widely used in infrared optics. Despite the practical importance their short range order is still not understood completely. The main problem is that...

In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped...

We aim to use total scattering and pair distribution function (PDF) analysis to determine the local structure of the disordered amide-borohydride, Na2BH4NH2. We wish to...

The UK nuclear industry is involved in a large effort to decommission nuclear power reactors and safely store radioactive waste. A key process is the vitrification of high level...

We designed and synthesized a series of new oxided ionic conductors Ba3M1+xTi1-xO8+x (M = Mo and W), which adopt a hybridized structure with the features of 9R perovskite...

We are about to submit a detailed pair distribution function study of a new lead-free ferroelectric material based on RMC analysis. This method will be applied in VT studies of...

We intend to use neutron diffraction and x-ray diffraction to investigate the structure of potassium and barium iron phosphate glasses, which are potential candidate systems for...

Zeolites are meso- and nano-porous framework materials with applications in many industries. The zeolite framework consists of corner-sharing tetrahedral units. The catalytic...

Glass-based phosphors have applications that range from light-emitting diodes to lasers. The optical properties of these materials depend on the coordination environment of the...

Phosphate glasses containing transition metal oxides, such as MoO3 and WO3, are of interest for various applications making use of their electrical properties. MoO3 and WO3 are...

Re-chargeable Li ion batteries play a key role in modern consumer electronics and may have an important part to play as energy storage devices in a low carbon economy of the...
