The organic salt guanidinium mesylate [Gdm][CH3SO3] is a promising phase change material for thermal energy storage applications. It has melting point Tm = 208 °C, and... -
Cation ordered transtion metal oxides
LaCa2Fe2GaO8 adopts a 3-layer cation-ordered structure. Magnetisation data collected from this phase exhibit two high-temperature anomalies consistent with the onset of... -
Spin-orbit transitions in CoV3O8
Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in... -
An investigation on the effects of cationic disorder on the ground state spin...
The proposal deals with understanding the paramagnetic fluctuations in CoV3O8 which have recently been investigated on MARI. This material displays cation disorder and strong... -
Microscopic Dynamics of Confined Water in Hexagonal Phase of REPO4 (RE=Y, La)
Confined water, a common natural phenomenon, shows very different structural, dynamical and phase behaviour vis-à-vis bulk, and it is depended on the host-water interactions.... -
Hydride conductivity in La2LiHO3
The arrangement of atoms in a solid, its crystal structure, is of key importance for its chemical and physical properties. This includes type of atoms are present, their... -
QENS studies of Na-ion battery materials
LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related... -
