The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to...

Reflectin, so named because of its high refractive index, is a protein expressed exclusively in cephalopods and forms reflectors responsible for dynamic iridescence and...

The exchange-striction mechanism, where parallel or antiparallel alignment of an ion's spin with its neighbour leads to displacements away from or towards the neighbour which...

Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D...

The rise of quantum materials observed in the past decades has been a source of great excitement for condensed matter scientists, with the flourishing of new concepts and...

From our previous data on BaFe2As2 and BaFe1.9Ni0.1As2, one may assume that the superconductivity only affects the low energy excitations. But for Ba0.67K0.33Fe2As2, the doping...

This proposal will use QENS to investigate the diffusion of propane and methylacetate in mordenite zeolite catalysts used for the carbonylation of dimethylether to make...

Magnetic nanoparticles are currently being investigated comprehensively. Our ball-milled TbCu2 nanoparticles show a core-shell structure in which the core orders...

Ba2CuTeO6 is a recently discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that it is extremely close to the theoretically predicted quantum...

We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the...

In recent years, the research related to agricultural wastes aiming to evaluate their potential for recycling as well as the elimination of the landfills increased dramatically....

This experiment will measure the microstructure of Amorphous Solid Water (ASW), a porous material that can be formed by vapour-depositing water onto a cold plate, an excellent...

In 1972, Haupt observed a giant enhancement of proton polarisation in NMR experiments on crystalline g-picoline. Key to this discovery was the implementation of quick...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

We have recently determined the structures of methanol-monoammoniate, and Me-hemiammoniate from neutron powder data. These are found to have different degrees of C-H...O...

We have prepared a new non-stoichiometric series Cr2-xInxGe2Te6. X-ray diffraction data can be indexed on the rhombohedral unit cell of the end-member (x=0) phase. This adopts a...

The aim of the present proposal is to establish the structure of the ferroelectric phase of CdTiO3 and to determine the nature of the ferroelectric-paraelectric phase...

We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger...

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...
