Liquid-Cell Transmission Electron Microscopy (LCTEM) is a method for studying the nucleation and growth of nanostructures either from solutions or during the electrodeposition, at the nanoscale and in real time. In the joint study between the researchers at the Department for Nanostructured Materials at Jožef Stefan Institute and National Institute of Chemistry we have shown that the radical-induced redox chemistry can be used to investigate various redox-driven dynamics for a wide range of functional nanomaterials, in situ, and under dynamic conditions by applying LCTEM. We successfully modelled radical-induced redox chemistry processes in LCTEM, including the complex kinetics of the radiolysis species and their influence on the redox chemistry of the materials under investigation. The results of this study were published in a highly ranked journal Chemical Science (IF = 9,5).
