The intermetallic Mo3Sb7 compound exhibits superconductivity at Tc=2 K and exhibits interesting physical properties in the magnetic susceptibility, electrical resistivity and...

It is well known that water is the medium in which the overwhelming majority of biological processes take place. In cell membranes water molecules are thought to be essential to...

This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is...

Atomistic characterisation of phase transitions in organic materials is important because of the role played by polymorphism in pharmaceuticals and agochemicals. Conventional...

A recent beautifully resolved INS spectrum of solid ammonia shows distinct differences in phonon states compared to initial calculation. This suggests that strong...

This proposal seeks to establish the importance of orbital ordering on the stability of the tetragonal phase in Cu doped SrRiuO3. Orbital ordering is believed to be a...

Zeolites are porous framework materials that have active catalytic sites inside narrow channels. Unwanted reactions create coke in the pores which may block access to the active...

Equations of state (EoSs) show how the thermodynamic variables of temperature, pressure and volume are inter-related. The ideal gas law, PV = nRT, is an example of an EoS which...

In the high-performance and low-cost (Mn,Fe)2(P,Si) magnetocaloric compounds, the detrimental hysteresis has been significantly reduced by balancing Mn:Fe and P:Si ratios, which...

Ammonium sulfate has a well-known order-disorder phase transition at -50 ºC: initially of interest for the ferroelectric behaviour in the low-temperature phase, this has...

NaxCoO2 has exceptional thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery applications and as a...

Most of the features exhibited by canonical glass-formers can also be found in systems with a high-degree of translational order. In addition to the well-known orientationally...

The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are...

The formation of silk fibres in both spiders and silkworms is characterized by a conversion of short range ordered structures in solution into long range ordered beta-sheet rich...

In recent experiments we accidentally observed the onset of nanophase segregation in concentrated LiCl-water solutions by increasing dilution, in the deeply undercooled regime....

Alkali metals are soluble in organic media when a macrocyclic complexing agent is used in order to drive the dissolution process by formation of complexed metal cations and...

Over the past two years I have carried out high-pressure surveys of the ammonia monohydrate (AMH) phase diagram using a Paris-Edinburgh press mounted on the D20 beam-line at the...

We are proposing 10 days of beamtime on IRIS to investigate the diffusion process of H2O molecules adsorbed on polyamide, surface material of reverse osmotic membranes currently...

Freezing of fluids confined at the nanoscale is of great importance for the understanding of their behaviour due to the confinement effects arising from the finite pore size and...

Calcium carbonates are highly important in geochemistry and especially in biomineralization. In nature, organisms can form each of the anhydrous polymorphs selectively for...
