Goethite mineral dissolution to probe the chemistry of radiolytic water in liquid-phase transmission electron microscopy

In this recent publication, the authors have used liquid phase electron microscopy to observe the dynamic behavior of geothite during dissolution under the irradiation of the electron beam. Kinetic simulations of the different radiolysis species provides insight into the redox and acidity of the liquid during the exposure to the beam. These interactions are very important to take into account when doing any in situ microscopy in liquids. Therefore, this paper opens up new perspectives on beam-induced radiation chemistry.
