The rational design of high-performance catalysts is hindered by the lack of knowledge of
the structures of active sites and the reaction pathways under reaction conditions, which can …

Compressed ultrafast photography (CUP) is a burgeoning single-shot computational
imaging technique that provides an imaging speed as high as 10 trillion frames per second …

Advances in attosecond spectroscopy have enabled tracing and controlling the electron
motion dynamics in matter, although they have yielded insufficient information about the …

Time-resolved electron microscopy aims to track nanoscale excitations and dynamic states
of matter at a temporal resolution ultimately reaching the attosecond regime. Periodically …

Metal–organic frameworks (MOFs) are hybrid materials constructed from metal clusters
linked by organic linkers, which can be engineered for target functional applications in, for …

The spatial and energy resolutions of state-of-the-art transmission electron microscopes
(TEMs) have surpassed 50 pm and 5 meV. However, with respect to the time domain, even …

Ultrafast electron diffraction (UED) is a technique in which short-pulse electron beams can
probe the femtosecond-scale evolution of atomic structure in matter driven far from …

Owing to their ultrahigh optical confinement, plasmonic nanolasers with cavity sizes beyond
the diffraction limit of light, are attracting increasing attention for pursuing extreme lasing …

Photoemission driven by ultrafast optical fields enables spatiotemporal control of electron
motion with extremely high precision. Here, we present a quantum model for ultrafast …

The statistical character of electron beams used in current technologies, as described by a
stream of particles, is random in nature. Using coincidence measurements of femtosecond …
