PhD: Low-dose scanning Transmission Electron Microscopy and spectroscopy of radiation sensitive nanomaterials
The project is based around the use of low-dose electron scanning transmission electron microscopy (STEM) on electron beam sensitive materials. Many common materials are sensitive to electron beam irradiation, including organic crystals, amorphous materials and biomaterials, with the electron beam being able to alter their size, morphology, crystallinity, and composition. By investigating the feasibility and limits of low dose STEM when working with electron beam sensitive materials, we hope to help enable research into materials where it has previously been challenging. An example of this is in Rob’s collaboration with Thokozile Kathyola, where they are applying low dose STEM to study nanoscale fuel detergent particles to investigate the presence of crystallinity.
Development of a methodology for low dose STEM imaging and analysis is of benefit for single particle analysis of complex particulate formulations including pharmaceuticals, fine chemical additives, food systems, polymers and colloidal systems.
