Providing a holistic understanding of radiation chemistry during in situ studies
Taming radiation effects during in situ studies in liquid phases is a major challenge for investigations with ionizing radiation, such as electrons or X-rays. In a recent work published in Advanced Science, researchers of FAU (IMN, CENEM, LEB, ICSP, LKO), Helmholtz-Institute Erlangen-Nürnberg for Renewable Energy, and Fraunhofer IISB have made a step further towards this goal.
By harnessing a novel tool for automated radiation chemistry simulations (AuRaCh), the research collaboration originating from GRK-1896 has studied the radiation effect on the evolution of gold nanoparticles. In conjunction with in situ electron microscopy using a graphene-supported microwell liquid cell architecture and in situ X-ray analyses they verified their simulations both qualitatively and quantitatively. By doing so the researchers provide a holistic understanding of irradiated aqueous HAuCl4 solutions.
