This proposal is a low-cost/high-gain first step in an ambitious project: namely, to develop a combined neutron scattering and electronic structure calculation approach as a...

Hydrogen binding to coordinatively unsaturated metal sites (CUMCs) in metal-organic frameworks (MOFs) has been extensively studied in our group using neutron powder diffraction...

One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is...

The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this...

This proposal builds on the success of our last INS experiment (RB1210041), which used TOSCA's new low energy capabilities to access and track the elastic line as well as the...

Zinc Oxide (ZnO) is a wide band gap semiconductor that has a number of interesting applications especially its optoelectronic (blue and near UV light emitting properties, as a...

Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk...

The objective of this experiment is to characterise four particular high-pressure polymorphs of various hydrates discovered by us in recent years during work carried out using...

The interaction of ammonia with binary hydrides (prototypically, the interaction of LiH with ammonia gas) is thought to be the predominant interaction for hydrogen production...

Zirconia-ceria ceramics are promising materials within automotive exhaust catalysts, exploiting the Ce3+<->Ce4+ redox reactions to store oxygen. For a Zr:Ce ratio of 1:1...

The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The...

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

We propose to perform a systematic study of the intermolecular librational mode of molecular water in the proton conducting hydrated alkali thio-hydroxogermanates...

Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

Our research group have been investigating the structure-property relationship in solid oxide fuel cell materials, with the aim of developing new materials with improved...

We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further...
