Polymeric films thinner than a 100 nm exhibits a variation of the glass transition temperature of a few tens of degrees and can brake up into discrete islands when heated near...

The family of hybrid Prussian blue analogues includes many electroactive materials, where organic cations moving within the pores of the cyanide framework cause unusual and...

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...

Materials with helical and double helical structure motifs are prone to display fascinating spring-type behaviour, i.e. a shallow energy surface along the spring-axis in which...

Hydrogen Storage still remains the technology bottleneck for a more widespread use of hydrogen. Solid complex hydrides such as amides, alanates and borohydrides have been...

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...

Thermoelectric devices are capable of converting thermal energy directly into electrical energy. The efficiency of a device is related to the characteristics of the materials of...

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...

We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste...

Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and...

The Li?N?H hydrogen storage system is one of the most promising candidates for hydrogen storage in vehicular applications and the addition of halide ions significantly increases...

In certain materials, notably with the spinel structure, orbital ordering can result in the formation of a ground state with electrons delocalising between small numbers of...

The selective adsorption of gases is essential to many technologies in the industrial, energy, semiconductor, food and medical sectors. The total adsorbent market is worth about...

We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....

In a number of recent experiments on the pure CeB6 compound, we have revealed strong quasielastic inten-sity in the normal (paramagnetic) state with a rich momentum-space...

Group 1 amides of general formula MNH2 are some of the most promising materials for hydrogen storage applications due to their relatively low temperatures of hydrogen evolution...

The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an...

The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are...

Thermogravimetric analysis on alkaline earth hydrides in St Andrews has revealed a remarkably fast exchange of deuterium and hydrogen by alkaline earth hydrides at relatively...

Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid...
