The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,...

The ambient-pressure Pnma phase of NiSi is a technologically important material used to form contacts in microelectronics. Recently we carried out the first study of NiSi at...

This is a proposal to drive the layered oxide chalcogenide Sr2NiO2Cu2Se2 from the high-spin state with long range magnetic order to the low-spin state, similar to that displayed...

Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity...

Recent published studies have identified a stable solid form of carbonic acid at high pressure. This proposal is for beamtime to collect the data to solve its crystal structure.

The most important scientific problems to solve for the future is how to efficiently convert and store clean energy. To realize all-solid-state devices and high-performance...

This proposal will explore the effect of elevated pressure on the behaviour of two important hydrogen peroxide solvates of the explosive CL-20. We will use neutron diffraction...

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...

This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of...

We will investigate the structure of 4-chloroimidazole a material, which undergoes extreme anisotropic thermal expansion,.as a function of pressure at a range of temperatures...

Pressure induced high-spin (HS) to low-spin (LS) transition in MnS2 was speculated by Chattopadhyay and von Schnering more than twenty years ago from their high pressure X-ray...

Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure....

Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life...

This experiment follows our ambient pressure characterisation of the Li intercalate of FeSe which is a superconductor with a Tc of 43 K. Li atoms, amide ions and ammonia...

In order to tackle emissions targets for CO2, there is increasing pressure to replace fossil fuels with renewable fuels. Biodiesel is one such renewable transportation fuel that...

We propose a high-pressure neutron powder diffraction study of the crystal structure of deuterated ammonium iodate, ND4IO3, which is known to undergo a ferroelectric phase...

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),...

Permanent magnets are essential for renewable energy technologies such as electric cars and wind turbines. Global demand for magnets is increasing, however, the elements used to...

Ruthenium-oxides are important strongly correlated electron systems: the bilayer ruthenate Sr3Ru2O7 shows field-induced electronic order, while single-layer Sr2RuO4 is an exotic...

The pressure-transmitting medium in a high-pressure experiment is usually thought of as an inert medium that allows the sample to be compresses rather than crushed. In organic...
