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... -
Interlayer and Interparticle Water in Clays
Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for... -
Low Temperature Properties of a Uniform S=1/2 Triangular Lattice System
It is proposed to use TF muSR to study the low temperature, low field part of the phase diagram of Ba3CuSb2O9, a system with a uniform triangular lattice of S=1/2 Cu ions that... -
Thermal expansion of recovered high-pressure ice polymorphs
The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD... -
In-situ thermoelectric measurements of copper chalcogenides
Thermoelectric devices are capable of converting thermal energy directly into electrical energy. The efficiency of a device is related to the characteristics of the materials of... -
Structures of ethanol ammonia cocrystals
Compounds of ethanol and ammonia have been known for over a century but no structural characterisation has ever been carried out. These materials allow us to examine a range of... -
Simultaneous Microwave Dielectric Spectroscopy and Neutron Diffraction Measur...
Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend... -
