Water Binding and Solvent Dynamics in Natural Deep Eutectic Solvents
Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being composed of a salt, the... -
Spin dynamics of pressure-induced heavy fermion superconductor CeRhGe2
The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh... -
Molecular and framework dynamics in CH3NH3PbCl3
We propose to use MARI to measure the molecular and framework dynamics in CH3NH3PbCl3 which has become of interest in the context of efficient photovoltaics. CH3NH3PbCl3 is... -
QENS studies of molecular hydrogen in K-doped electrospun graphite nanofibres
The physisorptive capability of graphite-based nanomaterials for hydrogen is strongly dependent on their surface areas and nanomorphologies. We have made electrospun graphite... -
