Formation and ammonia decomposition behaviour of lithium nitride hydride
Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride... -
Investigation of the phase transition in La2Mo2O9 from structural and conduct...
There has been significant interest in the oxide ion conducting material La2Mo2O9 as a new electrolyte after initial reports of conductivity as high as that of YSZ at lower... -
Phase Transitions and Orbital Ordering in SrRu1-xCuxO3.
This proposal seeks to establish the importance of orbital ordering on the stability of the tetragonal phase in Cu doped SrRiuO3. Orbital ordering is believed to be a... -
