The Earth¿s climate is strongly influenced by atmospheric aerosols. Organic surfactant films on these aerosols influences their size, optical properties and ability to act as...

Pyrolysis is considered as a sustainable way to generate energy from bio-oil, however, biochar – a solid residue by-product– is inevitably produced in the production line. We...

Although microemulsions have been widely investigated as potential drug delivery vehicles, relatively little work has been performed establishing the detailed molecular...

Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

In this proposal we shall explore the nature of electrospun fibres produced from blends of cellulose and polystyrene which we shall use as a model to develop high strength...

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...

Metal-organic perovskites offer many of the advantages of their ceramic analogues, with a range of exploitable functionality including ferroelectricity. Understanding the...

In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...

NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)...

We are proposing 4 days of beamtime on GEM to conduct the experiment on 10 alloy nanoparticles; PdxRu1-x (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) and PdRuM (M = Rh, Pt, Ir). We have...

Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...

The perovskite structure with general formula ABX3 describes many hundreds (if not thousands) of materials. Many have interesting and technologically important properties. The...

Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its...

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the...

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Li2FeSiO4 shows promising performance as a cathode but...

Antiferroelectric materials are attracting extensive attention due to their potential in energy storage applications. These materials exhibit a double polarisation-field...

The physisorptive capacity of graphite-based nanomaterials for hydrogen is strongly dependent on their internal surface areas and pore dimensions. We have made electrospun...

Hydrogen is an efficient energy carrier that can be produced from renewable sources and stored in alloys in solid-state for long period enabling the transition towards CO2-free...

This proposal seeks to investigate the polymorphism and polymerisation of glycolide. Glycolide is a six-memebered ring structure that polymerises into poly(glycolic acid) and is...
