The objectives of this proposal is to seek 2 days on POLARIS in order to test and complete a full commissioning of the latest design of our prototype in-situ reaction cell for...

Oxide-ion and proton-conducting materials attract considerable interest thanks to their application as electrolytes in solid-oxide fuel cells (SOFCs). We have recently...

Spin excitations is correlated with superconductivity in high Tc superconductors. The spin excitations in La2-xSrxCuO4 superconductors become weaker in overdoped region and...

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...

We propose to the measure the spin and orbital fluctuations associated with Vanadium in MgV2O4 using the MAPS direct geometry chopper spectrometer. This proposal will use the...

In recent years there has been a resurgence in research dedicated to ferroelectric materials primarily due to the combination of the requirement for Pb-free replacements for...

BiFeO3 is by far the most widely studied multiferroic material and yet many mysteries remain in the phase diagram. One mystery is the crystal structure of the high T gamma...

Bi4Ti3O12 is a well-known and studied layered perovskite; such phases are ferroelectrics, which have been used in random-acccess memories and other applications. Understanding...

This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the...

The aim of the experiment is to investigate the temperature evolution of the crystal structure for two transition metal oxides with low lattice thermal conductivities. This will...

Microwave dielectric ceramics are used in communications devices. Such materials need high relative permittivity, high dielectric quality factor and be temperature stable....

In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this...

Pb-based materials such as PbZrxTi1-xO3 (PZT) are widely used as transducers, actuators and sensors in a range of modern technologies due to their excellent piezoelectric and...

We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data...

We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how...

This proposal is concerned with determining the local structure of LaCoO3 and observing changes within this as the material undergoes some well characterised temperature driven...

We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and...

Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride...

Silicate spinels are important minerals in the transition zone region of the Earth and in order to understand seismic signals from these depths (550-660 km) we need to know the...

We request 3 days’ beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or...
