Recently, several perovskite-like ceramic-oxide solid solutions featuring pseudocubic symmetry have been reported to exhibit technologically promising dielectric and...

Perovskites are used in many applications such as electrode materials in fuel cells or as catalysts e.g. in syngas conversion, CO oxidation, N2O decomposition, or...

For the last two decades, many polymers have been tested to increase CO2 viscosity for enhanced oil recovery. Unfortunately, HC-polymers were found to be inactive for the...

BaB4O7 glass crystallises to different polymorphs of the same composition depending on the prior thermal history of the glass and the surface area of the sample. This indicates...

Hydrogen storage is considered to be one of the principal technological barriers in the transition towards a hydrogen-based economy. In this proposal, we plan to look at the key...

Nanoporous zeolites are well-known materials with huge industrial and commercial application in important areas yet their crystallisation mechanism remains under great debate....

Sr2IrO4 is an important material in condensed matter physics, displaying a novel Jeff=½ Mott insulating state and being a rare comparative system for understanding the high...

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...

2 days of beamtime is requested on Polaris to study the defect structure of an oxide-ion conductor Bi1-xBaxFeO3-x/2. RT total neutron scattering studies on samples heat treated...

We propose to examine the structure of anatase titanium dioxide (TiO2) obtained by different synthetic techniques (including hydrothermal and sol-gel) and of different particle...

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...

Molybdenum containing glasses have many potential applications. However, there is little information available on the structural role of molybdenum in glasses, and the limited...

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...

Defining when the practical use of Bronze Age swords changed from stabbing to cut-and-thrust weapons would have a huge impact on Bronze Age research. The change was accompanied...

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

Zeolitic imidazolate frameworks (ZIFs) are formed from inorganic nodes connected by organic ligands, and share structural features with zeolites. They have recently been...

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

Nanostructured carbons are promising precursors for a high-capacity reversible hydrogen storage material with fast kinetics, but the interaction of H2 with pure graphite is too...

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...

The European Medieval double-edged sword develops in the 11th century from the Viking Age sword. Already in the 10th century, some of the finest examples of the Ulfberht type of...
