Reflectometry studies of the mechanism of formation of mesoporous silicate fi...
Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from... -
Structural studies of thermochemical and phase-change naterials for heat storage
This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of... -
Investigation of the excitation spectrum in the 1D distorted diamond chain Az...
We propose to investigate the excitation spectrum of azurite in both zero field and applied fields up to 7T. Using inelastic neutrons on OSIRIS we hope to clearly resolve the... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to... -
