The response of the magnetic ordering of layered cobalt oxide chalcogenides to changes in electron count will be investigated in detail following a preliminary experiment at...

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...

The present scientific case concerns a glass-forming system with even less degrees of freedom, namely the occupational disorder of high-temperature phase (I, P21/c) of...

Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),...

We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers...

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...

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...

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...

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...

We propose to employ the neutron Compton scattering (NCS) in the realm of ionic liquids (iL), applying it to the protiated and deuterated variants of an archetipic IL, phosporic...

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...

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...

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

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

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...

Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...

By combining NDIS experiment and EPSR simulation we have been able to show with a previous experiment (RB 720500) two main phenomena for water confined in the MCM silica matrix....

The myelin sheath is a multilayered membrane wrapped around axons in the vertebrate nervous system; it enables the rapid transmission of nerve impulses. It contains a set of...

Water plays a critical role in determining the structure and function of biological system. A hydration level, h~0.2 g water/g protein, is often found to be the minimum...

Hybrid perovskites, composed of an organic cation, inside a post transition metal halide framework, have emerged since 2009 as simple, low cost solar cell materials, with power...
