Our objective is to determine structural models for some complex, mixed-metal oxide phases that are as complete as possible using analysis of PDFs produced from total neutron...

On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the...

Recent work has shown that localised high-pressure rolling of weld seams can be a very effective means of reducing the damaging residual stresses created during the welding...

Commercial access. Agreed for 13th March 2013

Peptoids are synthetic mimics of peptides (the natural building blocks of proteins) in which the side chain is attached to the backbone amide nitrogen instead of the central...

Yttrium doped glasses are of considerable interest due to their potential for use as in-vivo radioactive beta- emitters for localised treatment of liver cancer and other...

Both BiFeO3 and KNbO3 are technologically important materials. BiFeO3 exhibs room temperature magnetic and ferroelectric ordering whilst KNbO3 is a lead free ferroelectric....

Catalytic processes leading to the functionalization of organic molecules by boron-containing reagents are highly topical ¿ ranging from transition metal catalysed hydro- and...

One potential solution to reduce the greenhouse gas emission is the generation of fuels through thermochemical dissociation of CO2 and H2O. Previous studies have shown that...

BiFeO3 is one of the most widely studied multiferroics (ferroelectric TC ~ 830°C, and antiferromagnetic TN ~ 370°C). Rare earth doping has been shown to be a suitable method of...

Ammonia borane (AB) is a promising hydrogen storage material with up to 12 wt% obtainable from 100 to 150 C. Desorption temperatures can be lowered towards targets and kinetics...

Mesopotamian iron oxide objects in the form of Roll seals and Weight are typical for the Old Babylonian Period (ca. 2000-1600 B.C.). In the museums they are usually cataloged as...

This proposal aims to investigate the short range structure and morphology of FePt NPs, of average diameter ~ 2 nm, and their surrounding surfactant layer (oleic acid and...

BiFeO3 attracts considerable attention because of its multiferroic and ferroelectric properties. Nd-substitutions in antiferromagnetic BiFeO3 induce a significant ferromagnetic...

This proposal relates to the structural studies of cationic surfactant adsorption on an iron oxide metal surface. The driving force for the adsorption of cationic surfactants to...

Abstract. We request one day of beamtime on POLARIS to collect Neutron Diffraction (ND) data from a variety of ACu3Ti4O12-type perovskite-related compounds that exhibit higher...

We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,...

In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this...

We propose to investigate the detailed spectroscopy of the expanded metal systems 7Li(NH3)4 and 7Li(ND3)4 by inelastic neutron scattering. 7Li(NH3)4 shows multiple phase...

This proposal requests neutron diffraction beamtime to study a series of novel metal fluorophosphates and acid pyrophosphates with potential as ionic conductors....
