研究领域

Our research spans the fields of energy materials chemistry and the atomic, molecular and nano-structure of materials. Our energy materials studies centre on the discovery and characterisation of novel chemical energy storage systems and we have a particular focus in developing hydrogen and ammonia as energy vectors. We use neutron and synchrotron X-ray diffraction combined with computational modelling as our principal techniques for the structural elucidation of materials. In the area of energy materials, our studies have included in-situ neutron powder diffraction measurements combined with gravimetric analysis for the study of reversible lightweight hydrogen storage materials and mass spectrometry for the investigation of novel ammonia decomposition materials.
