Our long-term aim is a detailed study of the manufacture of wootz (the so-called Damascus steel)a high-C% cast steel which was very slowly cooled and very carefully forged so as...

Oxalyl chloride, which is a liquid at RT, forms a disordered phase (I) on cooling to 260 K. This phase is unstable with respect to an ordered phase (II) below 250 K, but in...

Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel...

The perovskite-like family of ammonium formate frameworks AB(HCO2)3, where A is a divalent metal ion and B is an (alkyl)ammonium or guanadinium, is of great interest for its...

This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and cobalt imidazolate. Imidazole (IM) is a small, flat...

We propose to measure the inelastic scattering S(Q,E) maps from barium in both the polycrystalline and liquid phases, based on the fact that there are intriguing similarities...

This proposal is a low-cost/high-gain first step in an ambitious project: namely, to develop a combined neutron scattering and electronic structure calculation approach as a...

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

Our long-term aim is a detailed study of the Arms & Armour in the Wallace Collection, London, which contains over two thousand items and is one of the most important...

Recent work has revealed that metal-organic frameworks (MOFs) can also exhibit this multiferroicity. These materials are particularly interesting since their structures are...

Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk...

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

Oxalyl chloride (mpt. 260 K), forms an ordered phase at low temperature, but a disordered phase between 250 K and the melting point. In previous beamtime we aimed to carry out...

As part of an ongoing effort to understand the underlying physics of MOFs, we propose to study the local structure and dynamics in two quartz-like systems: indium deuterium...

The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are...

This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,...

It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....

We propose to measure total scattering from Rochelle Salt in order to provide new insights into the re-entrant phase transitions in this material. Rochelle Salt is an old...

The recent discovery of superconductivity in a series of iron pnictide materials has led to the anticipation that they might lead to new insights into the origins of...

Bismuth Ferrite (BiFeO3) is the archetypal multiferroic material and as such has been copiously studied using a wide variety of techniques. Despite this, new structural and...
