Abstract Scope The development of nanosecond and faster photoemission electron sources offers the chance to move the high spatial resolution world of electron microscopy into the ultrafast world of materials dynamics. The interaction of the materials subjected to either a pulsed or a continuous laser beam generates extremes of temperature and pressure in the material. Therefore, the incorporation of high temporal probing capabilities and lasers to the TEMs has been a critical development required to discover new knowledge about the dynamic evolution of materials on varying time and length scales. In this presentation, examples of single-shot ultrafast electron microscopy studies will be presented for selected systems. Short lived transient processes involved in dynamic processes in materials will be discussed to obtain new insights. Additionally, the potential of novel in-situ stages for various data acquisition schemes to push the envelope of ultrafast electron microscopy for the investigation of materials will be discussed.
