Hydration of Laponite powder
In a recent experiment on NIMROD (RB1120193) we have studied the microscopic structure of Laponite suspensions at 2 concentrations, namely Cw=1.5% and Cw=3.0%, at both the... -
Dipolar frustration on the triangular lattice: Order and disorder in AgNCO
We propose to use neutron total scattering to characterise isocyanate (NCO-) orientations within the orientationally-disordered phase of AgNCO. The arrangement of NCO- ions in... -
Non-Fullerene Based Acceptors for Organic Solar Cells
Organic Solar Cells (OSCs) have attracted substantial commercial and scientific interest as they provide a pathway to realizing a renewable energy source that is portable... -

Local structure and oxygen nonstoichiometry in the cubic Ba0.5Sr0.5Co0.8Fe0.2...
Oxygen nonstoichiometry (d) of perovskite-type Ba0.5Sr0.5Co0.8Fe0.2O3-d (BSCF) was recently studied by combination of TGA, coulometric titration and neutron diffraction (ND).... -
Structural Observation of the Self-Assembly Kinetics of Cyclic Peptide Nanotubes
Cyclic peptides with alternating side chain stereochemistry are capable of self-assembling into long nanotubes. The conjugation of polymers to these peptides renders the... -
Encapsulation in Mixed Cat-anionic Surfactant Polymer Films
This proposal continues our investigations into polyelectrolyte-surfactant films at the air-solution interface. Using mixtures of cationic and anionic surfactants (CTAB/SDS) we... -
The role of defects in the pressure-induced octahedral tilting in Prussian bl...
We propose a high-pressure study of two Prussian blue analogues, Mn[Co(CN)6]0.67 and MnPt(CN)6. Our high-pressure XRD study shows a phase transition from cubic to rhombohedral... -
High-pressure studies of insensitive explosives: Nitroguanidine (NQ) and N-gu...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of two insensitive energetic materials - Nitroguanidine (NQ) and N-guanylurea-dinitramide... -
Structural analysis of Li-rich layered oxides synthesized at low temperatures
This rapid access proposal is aimed at investigating the local cationic and anionic environments of a model Li-rich layered oxide, Li1.2Mn0.6Ni0.2O2 (LNMO), through neutron and... -
Quantum dynamics in a J_eff=1/2 isotropic triangular-lattice antiferromagnet ...
This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum magnets. A canonical model is the spin-1/2 triangular antiferromagnet... -
Cross coupling between ferroelectricity and antiferromagnetism in the multife...
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... -
Vacancy Distribution in Praseodymium Doped Ceria
Doped cerias are currently being used as oxide ion conducting electrolyte materials in solid oxide fuel cells (SOFCs). Depending on the nature and concentration of the dopant... -
Local Structure of Bi6WO12 and Bi28Re2O49 Oxide Ion Conductors: Role of Varia...
Oxide ion conductors are technologically important materials with applications in solid oxide fuel cells, oxygen sensors /pumps and membranes for oxygen separation. Two types of... -

Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
Understanding pressure-driven structural changes in FePO4-II
The room temperature high pressure behaviour of FePO4-I has been investigated and a phase transition at around 2.5 GPa to the orthorhombic phase (FePO4-II) accompanied by a... -
An attempt to measure sorption through strain induced deformation
Zeolite catalysts are highly porous materials that take up gases and vapours into their pores. Accommodating the guest molecule inside the host framework leads to distortion... -
Development of neutrons as entangled quantum probes
We recently completed an experiment on LARMOR at ISIS that proved that each individual neutron prepared for a Spin Echo Small Angle Neutron Scattering (SESANS) measurement is in... -
Local boron and oxygen structure in lanthanide orthoborates LnBO3
We propose to carry out neutron total scattering on a series of five compounds with the formula LnBO3 (Ln = Y, Tb, Ho, Er, Yb). This will enable us to study the B--O distances...
