Thermal expansion of recovered high-pressure ice polymorphs
The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our... -
Melanins vibrational behaviour as a function of temperature and hydration to...
Electroceuticals is the attempt to speak the electrical language of the nerves to achieve higher treatment effect. Thus, the search is on to develop devices to enhance... -
Interfacial layer structure of designed lipopeptides at the solid/water inter...
Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a... -
Structures and thermal expansivity of recovered phases of urea II & III
Urea is a prototypical hydrogen-bonded small molecule that has stimulated considerable fundamental research into its structure, elastic properties and polymorphism. Amongst the... -
Structural Disorder in the Quantum Spin Liquid Candidate YbMgGaO4
Quantum spin liquids are novel magnetic states in which quantum entanglement suppresses conventional magnetic order. Understanding the effects that stabilise such states is an... -
Coupling of chains in a new, highly tuneable, isostructural series of model q...
Here we propose measurements on a unique, newly synthesized series of coordination polymers based on chains of Cu2+ ions. These have been designed with the intention of... -
In situ diffraction studies of cathode materials for Li ion batteries
Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid... -
Correlations between local magnetism and spin-orbit transport physics in topo...
One of the main challenges in spintronics research is to provide a link between magnetic elements and conventional electronic circuits. A novel approach to this old problem is... -
Dynamical Perovskites
Hybrid perovskites, composed of an organic cation, inside a post transition metal halide framework, have emerged as simple, low cost solar cell materials, with power conversion... -
Tuning the low-temperature magnetism of spin ice Dy2Ti2O7: Y-substitution and...
The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose... -
Further studies of the ethanol-to-gasoline reaction
In our recent beamtime (RB 1820043 TOSCA and RB 1820044 MAPS), we prepared a series of ZSM5 samples that had undergone the ethanol-to-gasoline (ETG) reaction for different times... -

Vanadium based compounds have attracted considerable interest as positive electrode materials for Li ion batteries. This is due to vanadiums ability to display a range of... -
The phase stability of alpha-glycine at high pressure
Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common... -
The Power of Neutron Reflectivity for Batteries
Catastrophic failures of lithium batteries is a major safety concern, however our understanding and control over the mechanisms of these failures is still lacking. Lithium is... -
Equations of state of D2O ice III and ice V
The high-pressure forms of ice, phases III and V, are the equilibrium solids in contact with liquid water at pressures between 2.5 - 5.5 kbar. Consequently, their properties are... -
