Project description

In various scientific disciplines (e.g. cosmo- and geochemistry, environmental sciences, toxicology and biomedicine), there is a strong demand to develop techniques that enable linking the (quantitative) spatial distribution of chemical elements within the investigated materials to their three-dimensional (3D) internal morphology/structure down to nanoscopic resolution levels. This project will significantly advance non-destructive 3D elemental/structural analysis for high-profile Earth and planetary science research, making use of advanced laboratory and synchrotron-based X-ray hyperspectral-imaging and absorption micro-CT based methodologies. Our ultimate goal is to optimise these non-destructive experimental approaches for the quantitative chemical/structural micro-/nano-analysis of unique extra-terrestrial matter, originating from carbonaceous asteroids 162173 Ryugu and 101955 Bennu, returned to Earth respectively by JAXA's Hayabusa2 and NASA's OSIRIS REx missions.
