The Transmission Electron Microscopy TEM laboratory is a state-of-the-art facility equipped with a FEI Tecnai G2 F20 X-Twin transmission electron microscope and a FEI FIB200TEM Focused Ion Beam device for specimen preparation. The laboratory provides powerful techniques for characterization of crystal structure, microstructures and chemical composition of materials down to a near atomic level.

TEM sample holder:
Liquid-phase transmission electron microscopy (LP-TEM) allows for in-situ observations of the dynamic behaviour of materials in liquids at the highest spatial and temporal resolution in controlled environments (e.g. fluid properties and temperature). The option to observe such processes in real time has only been accurate enough to apply it to complex systems in the last 5 years. Nevertheless, electron beam induced changes in pH, nucleation rate and radiolysis can be a challenge and must be accounted for. The thickness of the liquid layer must also be considered; thin enough for the best possible spatial resolution but thick enough to hold a sufficient volume a fluid for scalable physical and chemical processes.
