Thermal batteries are primary batteries which find use in applications such as emergency power supplies in aircraft. They are required to provide a constant power over a given...

To determine the temperature dependence of the structures of new mixed and ionic conducting materials in the n = 2 ruddlesden-popper,mellilite and pyrochlore systems.

We propose to investigate the interplay of magnetic and structural properties in the multiferroic PbFe1/2Nb1/2O3 (PFN). PFN is the magnetic analogue of the archetypal lead based...

Hydrotalcites are anionic clays which have a variety of applications, including use as environmentally friendly catalysts and catalyst precursors. In this experiment we propose...

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...

The origin of a mysterious pseudogap region in high-Tc superconductors is a challenging issue. It was proposed that the pseudogap is caused by a circulating-current order...

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...

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...

When MgH2 is processed under relatively mild milling conditions it exhibits a two-step thermal decomposition process where loss of hydrogen is associated with each endothermic...

We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a...

Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...

This proposal will study the temperature dependence of the structure of a novel perovskite oxynitride SrTaO2N in order to establish how anion ordering impacts on the coupling of...

Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when...

There are growing demands to reduce the global CO2 footprint and to adopt alternative, sustainable fuels. Ammonia (NH3) is one such alternative, producing only water and...

A definitive structural model of LiCaN from powder neutron diffraction (PND) is an important first step towards a systematic study of the process and mechanism of hydrogenation...

A new generation of low-power high-density information storage would be enabled by the development of ?multiferroic? materials which function at or above room temperature. Such...

Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when...

Thermal batteries are used in applications were high reliability is a key requirement. They can be stored for decades and activated in less than a second. Most contemporary...

In extension of our previous study on particle size dependent solubility limits in nano-sized LiFePO4 we wish to extend our study to temperature dependent solubility limits in...

Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy...
