Ordered double perovskites (also known as elpasolites) have the general formula A2BB’O6 where A is generally a rare earth metal or alkaline earth metal and where B and B’ are...

The quasi-kagome Kondo lattice CeRhSn exhibits intriguing properties, which ascribe to quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide...

There is an interest in understanding the nature of fluoro-alumino-silicate glasses based upon the apatite stoichiometric composition and of potential within ionomer cements for...

Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations...

Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and...

We ask for 4 days on NIMROD to study the atomic- and intermediate-range order of ammonia-borane (AB) intercalated into mesoporous MCM-41. Ammonia borane is one of the leading...

Nimrod is a unique instrument that bridges atomic resolution solution scattering with small angle scattering. The opportunity therefore exists to probe both the microscopic...

The formation of charge and spin density wave (CDW and SDW) states in metallic systems isdriven by Fermi surface instabilities that are often found to compete with...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

PbCoO3 used to be the “missing link” in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC...

We have found that the 134-perovskite, HgMn7O12 (HgAMnA’3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both...

This proposal will explore the effect of elevated pressure on the 3,4,5-Trinitropyrazole (TNP). TNP releases a large amount of dinitrogen gas as a detonation product which is...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...

Cellulose, known as a fascinating biopolymer and a never ending-source of new sustainable materials, is attracting increasing attention in different fields owing to its...

We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste...

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 will exploit the unique capability of NIMROD to bring new understanding to the way in which long chain polymers, specifically stereoregulqr polypropylenes, crystallise. There...

We propose to study the influence of deposition rates and annealing effects on microporous amorphous solid water samples (ASW) using NIMROD. The data will allow us to monitor...

One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of...
