Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
Crystal structures of Na2MoO4.10H2O, Na2WO4.10H2O and Na2MnO4.10H2O.
Chemical substitution is a valuable technique for probing the behaviour of materials since this exerts a stress comparable in many respects to changes in pressure or... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
D2O Vapour Diffusion at the Air Water Interface
A theoretical estimate of the H/D exchange rate for an open trough (e.g. D2O in ambient atmosphere, 50% relative humidity) yields an amount of exchanged liquid of the order of... -
Assessing a new system of hard sphere colloids using spin-echo SANS
We have recently developed a new system of refractive-index matched nanoparticles. This system has advantages over a extensively used one of polymer latexes; ours 1) can be... -
