Electron energy loss spectroscopy on new battery materials
Projects in Material Science point to an understanding of the structure-property relationship of materials with technical application (e.g. nanoparticles, batteries and glass ). Studies using Transmission electron microscopy on structure and texture allow to draw conclusions about the physical properties of materials.
