About this episode

This episode explores operando Transmission Electron Microscopy with guest Patricia Kooyman.

Seeing atomic scale interactions in real time may sound like science fiction, but operando TEM (Transmission Electron Microscopy) has made it science fact. Unlike traditional TEM, which looks at static samples, operando TEM enables scientists to watch materials evolve dynamically while they undergo reactions. In this episode, we sit down with Patricia Kooyman, a professor at the University of Cape Town, to explore the science behind this technique as well as her unique history with it. This episode is sponsored by Momentum Transfer. They have an upcoming Powder Diffraction workshop at Politecnico di Bari in Italy. This 3 day workshop runs from September 29th to October 1st, 2025.
