Purothionins are a family of cationic cystiene rich plant defence proteins which have been shown to have a wide spectrum of activity due their ability to permeate cellular...

Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we apply for a...

We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means of...

Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to...

The proposal requests time on OSIRIS to measure the low-energy magnetic fluctuations in CeRhSi3. This compound is a noncentrosymmetric superconductor under pressures of ~10...

The density-driven structural transformations in the magnesium silicate glass MgSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of...

This experiment seeks to continue previous work on PEARL, whereby the phase is altered in the room temperature multiferroic BiFeO3 - PbTiO3 using hydrostatic pressure with the...

CuFe1-xCrO2 has potential applications as an SOFC cathode material. It exhibits and interesting transformation on oxidation. This is a follow on from our recent HRPD experiment...

It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =...

The proposal requests time to measure the low-energy excitations in CaFe2O4 as a function of temperature. Previous experiments have observed a series of in-gap states at high...

We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data...

Projected climate change is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and reflectivity, important climatic effects....

KTiOPO4 (KTP) is a well known non-linear optical material. Its crystal structure has highly asymmetric Ti-O bonds, a rigid TiO6-PO4 lattice and K cations trapped in cages. The...

We will investigate a series of amorphised zeolitic solids and determine the short and medium range order structures and more importantly the nature of pore-size when we go from...

This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well...

Inelastic neutron scattering has been used to study adsorbed species on catalysts for more than 30 years. All of this work has one feature in common: they are all ¿snapshots¿ of...

Plastic bags are used as containers for storage of donated blood. These bags are typically made out of PVC plasticized with dialkylphthalates (e.g. DEHP), which migrates into...

A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most...

In situ high-pressure neutron diffraction will be used to investigate the pressure-induced transformation of the Al coordination environment in a prototypical aluminosilicate...
