Thermodynamic Control of Isotopic Polymorphism
Co-crystals of 4-methylpyridine and pentachlorophenol (MP-PCP) exhibit the very unusual property of isotopic polymorphism, formation of different phases by samples differing... -
The icy-moon analogue of MgSiO3-perovskite: MgSO4.9H2O a high-pressure study
Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and... -
Investigation of glycolide-h4 and d4 at high pressure.
This proposal seeks to investigate the polymorphism and polymerisation of glycolide. Glycolide is a six-memebered ring structure that polymerises into poly(glycolic acid) and is... -
In-situ neutron diffraction during reversible deuterium loading in under-stoi...
Hydrogen is an efficient energy carrier that can be produced from renewable sources and stored in alloys in solid-state for long period enabling the transition towards CO2-free... -
INS studies of molecular hydrogen in K-doped electrospun graphite nanofibres
The physisorptive capacity of graphite-based nanomaterials for hydrogen is strongly dependent on their internal surface areas and pore dimensions. We have made electrospun... -
Pressure driven phase transitions in antiferroelectric, PbZrO3
Antiferroelectric materials are attracting extensive attention due to their potential in energy storage applications. These materials exhibit a double polarisation-field... -
In-situ Battery Discharge Studies of Thermal Batteries using Transition Metal...
Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the... -
P and Al substitutions in the lithium battery cathode Li2FeSiO4
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... -
Unusual polymorphism in sodalites
We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible... -
The quest for fully hydrogen-ordered ice XIV
Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its... -
Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations... -
Neutron Total Scattering Investigation of LaCoxMn1-xO3 Perovskites
The perovskite structure with general formula ABX3 describes many hundreds (if not thousands) of materials. Many have interesting and technologically important properties. The... -
Structures and microscopic miscibility for nanoparticles of palladium-rutheni...
We are proposing 4 days of beamtime on GEM to conduct the experiment on 10 alloy nanoparticles; PdxRu1-x (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) and PdRuM (M = Rh, Pt, Ir). We have... -
Roles of magnetic anisotropy and inter site exchange interactions in the temp...
NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)... -
Magnetic and Structural Studies on Oxychalcogenides
In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and... -
