In search of origin of metal-insulator transition in honeycomb structure Li2RuO3
Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic... -
Overcoming Chemical Reaction Equilibrium: Determining the Chemical Potential ...
We have developed and demonstrated a novel process to overcome chemical reaction equilibrium constraints on an important reversible industrial chemical reaction by using... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -

Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to... -
Understanding Chemical Expansion in Perovskite Oxides: Impact of Long-Range D...
"Chemical expansion" occurs when some ceramics expand upon releasing oxygen. Their ability to effectively "breathe" oxygen makes them of use in sustainable energy... -
The structures of simple halogen bridged complexes
We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a... -
