Total scattering from multiferroic bismuth ferrite
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... -
NIMROD: Continuation of the Structural Investigations of the Surfactant Coati...
This proposal aims to further investigate the short range structure and morphology of FePt NPs, of average diameter ~ 2 nm, and their surrounding surfactant layer (oleic acid... -
Structural study of oxygen ion conduction in microporous Mayenite
The crystal unit cell of mayenite, 12CaO.7Al2O3, consists of a cubic lattice of [Ca24Al28O64]4+ with the remaining 2*O2- contained in cages, which are linked by channels within... -
Structural studies of Fe-pnictide superconductors using neutron total scattering
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... -
Ferroelectric phase transition in Rochelle salt
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... -
Understanding the effects of pressure and temperature on the structure of an ...
The discovery of superconductivity in iron-pnictide materials has generated much excitement in the past year about possibly unifying mechanisms for high-temperature... -
Local structure, dynamics and magnetism of the phases of cobalt imidazolate
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,... -
Structure and dynamics of quartz-like metal-organic frameworks (MOFs)
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... -
How molecular solids prepare for phase transitions: The phase transition in o...
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... -
The Dynamics of Breathing Metal-Organic Frameworks from Total Scattering
Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these... -
Investigation of the Negative Thermal Expansion in (Sr,Ca)FeO2 with FeO4 squa...
SrFeO2 bears a square planar oxygen coordination around Fe2+. The rarity of this structure led us to study the substitution of strontium by calcium and we obtained the solid... -
Local structure and dynamics in metal-imidazolate frameworks
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... -
Local structure study of the order/disorder ferroelectric transition in [ND4]...
We will carry out a definitive local structure investigation of the ferroelectric transition in [ND4][Zn(DCOO)3]. This compound is seen as the canonical example of a... -
Study of nano-electrode materials for Li-ion batteries combining small-angle ...
Nano-materials are of interest in the field of energy conversion and storage due to properties not seen for the bulk. However, due to their non-periodic nature, the atomic... -
Cubic SnMo2O8 - a PTE Puzzle
Experiments (many at ISIS) using crystallographic methods, total scattering, inelastic neutron scattering and theory have provided a detailed picture of the origin of strong... -
NIMROD: Structural Investigation of Surfactant Coatings of FePt Nanocrystals
This proposal aims to investigate the short range structure and morphology of FePt NPs, of average diameter ~ 2 nm, and their surrounding surfactant layer (oleic acid and... -
Vacancy clusters and local magnetic structure of wüstite, Fe(1-x)O
The nature and distribution of vacancy defects in wüstite, Fe(1-x)O, is an important problem because the structural and dynamical properties of the mineral - both of which are... -
Variable Temperature studies of an anomalous proton sponge benzoic acid co-cr...
As part of a long-running programme, we have identified many co-crystallisation systems producing hydrogen-bonded molecular complexes yielding fascinating X-ray diffraction and... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Anion correlations in Ta oxynitrides
Transition metal oxynitrides with the perovskite structure type are an emerging class of functional materials with a variety of interesting optical, photocatalytic, dielectric...
