Ferroelectric BaTiO3 (BT) constitutes a base system for many practical applications ranging from classical capacitors to tunable dielectrics. A dielectric response in BT is...

In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of...

Research focused on improving the efficiency of gas turbines is of great importance for energy generation and transportation. A much desired way of achieving this is the...

Migration and surface segregation of low molecular weight oligomers in adhesive formulations is a poorly understood, but hugely important phenomenon, responsible for most of the...

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...

Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity...

In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular...

The primary aim of this proposal to investigate a series of newly discovered Bi- containing ferroelectric systems based on Bi(Me’Me’’)O3-PbTiO3 perovskite through studying their...

In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of...

Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these...

Recent published studies have identified a stable solid form of carbonic acid at high pressure. This proposal is for beamtime to collect the data to solve its crystal structure.

Nd2Zr2O7 is a new candidate prominent to quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field...

This proposal will explore the effect of elevated pressure on the behaviour of two important hydrogen peroxide solvates of the explosive CL-20. We will use neutron diffraction...

Very recently, we have studied the crystalline structure of the C0-phase H2-filled ice (recovered at room pressure and low temperature) and ice XVII, a new form of ice...

This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of...

Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical...

The Earth's climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important effects. Common...

With the decreasing cost of energy generation by renewable sources, energy storage is becoming increasingly critical to energy security across the globe. Lithium iron phosphate...

Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

It is commonly accepted that the recording of holograms with atomic resolution requires singlecrystalline samples. Closer analysis, however, shows that the reduced information...
