We will use the high resolution of HRPD and the excellent long d-spacing data available on OSIRIS to investigate the phase transitions in Sr1-xNaxFe2As2 which are associated...

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...

The The recent discovery of superconductivity in FeAs-containing compounds (often known as the pnictides has provided a great stimulus to experiment and theory in the study of...

The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

Magnetism and superconductivity compete and coexist in many of the high temperature superconductors, and the newly discovered iron arsenides are no exception. Muon-spin rotation...

This experiment follows our ambient pressure characterisation of the Li intercalate of FeSe which is a superconductor with a Tc of 43 K. Li atoms, amide ions and ammonia...

This proposal seeks neutron diffraction beamtime to study two important systems. We have demonstrated that monofluorophosphate (PO3F) can be substituted into gypsum (CaSO4.2H2O)...

Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of...

This is a proposal to fully characterise the crystal structures of the superconducting metal/ammonia intercalates of FeSe made using low temperature methods. In particular we...

Metal-doped TiO2 have particular applications as in catalysis of a range of reactions as well as in luminescence materials. Our strategy is to make well-defined molecular TixOy...

The purpose of this experiment is to gather structural data on the electron-doped derivatives of LiFeAs obtained by substituting some Fe by Co or Ni. In particular these data...

Through low temperature fluorination of AFeO3-x (A=Sr, Ba) it is possible to prepare the oxide fluorides AFeO2F, which are antiferromagnetically ordered at room temperature. In...

During our recent experiment (RB1310434) we were able to use ALC to characterise the radical states formed in [Fe2(µ-pdt)(CO)4(PMe3)2] and [Fe2(µ-pdt)(CO)4(CN)2]2- at two...

We have a continuing interest in the structural role of lone-pair cations in glasses. Thallium oxide behaves unusually in borate glasses, not only in terms of its own...

We will use POLARIS to determine the structures of the high temperature superconducting intercalates obtained by the reactions between FeSe and deuterated ammonia solutions...

Our previous studies of superconducting LiFeAs derivatives revealed a significant difference in Uemura scaling compared with all other studied pnictides. This experiment is...

The reversible interconversion of protons and dihydrogen is an electrochemical process of fundamental importance to a hydrogen economy. The process requires catalysis to proceed...

This proposal requests neutron diffraction beamtime to study a series of novel metal fluorophosphates and acid pyrophosphates with potential as ionic conductors....

In this experiment we will determine the detailed structure of the 6 K superconductor LiFeP and phases close in composition which are iron rich: Li1-xFe1+xP. This will enable...
