Ultrafast EELS, with combined energy, time, and spatial resolution in a transmission electron microscope, has recently enabled transformative studies of photoexcited nanostructure evolution and mapping of evanescent electromagnetic fields. This article aims to describe state-of-the-art experimental techniques in this emerging field and its major uses and future applications.Materials Science, MultidisciplinaryPhysics, AppliedMaterials SciencePhysicselectron energy-loss spectroscopy (eels)laser-induced reactionnanoscaleelectronic structureoptical propertiesnear-fieldin-situdiffractiondynamicsresolutionsurfacemodetext::journal::journal article::research article
