This set of movies illustrates and complements my PhD thesis "Advanced analytical electron microscopy applied to Solid Oxide Cell materials and their degradation " conducted at Ecole Polytechnique Fédérale de Lausanne. The movies were obtained after alignment of images resulting from the observation of solid oxide cell material exposed to high temperature in an environmental scanning electron microscope. In the file name, chapter and section numbers are written to help the reader make the link between the video and the thesis. The name of the sample is written in every file name. If the movie refers to a specific figure in the thesis, the figure number is also added to the file name. Optionally, the subject of the movie can be specified (particularly when several movies are related to the same sample). The appendix A of the thesis (Summary table) is also added so the conditions in which the movies were recorded can be easily found.
