The growing field of ultrafast materials science, aimed at exploring short-lived transient
processes in materials on the microsecond to femtosecond timescales, has spawned the
development of time-resolved, in situ techniques in electron microscopy capable of
capturing these events. This article gives a brief overview of two principal approaches that
have emerged in the past decade: the stroboscopic ultrafast electron microscope and the
nanosecond-time-resolved single-shot instrument. The high time resolution is garnered …
