Imaging CF3I conical intersection and photodissociation dynamics with ultrafast electron diffraction
Science, 2018 Motion picture of a conical intersection In most chemical reactions, electrons move earlier and faster than nuclei. It is therefore common to model reactions by using potential energy surfaces that depict nuclear motion in a particular electronic state ...

Virtual-diagnostic-based time stamping for ultrafast electron diffraction
Physical Review Accelerators and Beams, 2023 In this work, nondestructive virtual diagnostics are applied to retrieve the electron beam time of arrival and energy in a relativistic ultrafast electron diffraction (UED) beamline using independently measured machine parameters.

P doped random C20 fullerite - model structure for fullerene-like CPx [PDF]
, 2013 Carbon-based amorphous and fullerene-like (FL) thin films have a great potential due to their mechanical resiliency. TEM investigation and interpretation of results from FL structures embedded in bulk phases is not straightforward.

Rapid Structure Determination of Microcrystalline Molecular Compounds Using Electron Diffraction
Angewandte Chemie, 2018 Chemists of all fields currently publish about 50 000 crystal structures per year, the vast majority of which are X‐ray structures. We determined two molecular structures by employing electron rather than X‐ray diffraction.

Electron holography on Fraunhofer diffraction
Microscopy, 2019 Electron holography in Fraunhofer region was realized by using an asymmetric double slit. A Fraunhofer diffraction wave from a wider slit worked as an objective wave interfered with a plane wave from a narrower slit as a reference wave under the pre-Fraunhofer condition and recorded as a hologram.

Coherent Electron Source for Ultrafast Electron Diffraction and Imaging
EPJ Web of Conferences, 2013 We numerically investigate the suitability of photoexcited nanotips as a source of coherent femtosecond single electron pulses for ultrafast surface-sensitive electron diffraction and non-destructive imaging with low-energy electrons.
