Femtosecond single-electron diffraction [PDF]

Structural Dynamics, 2014
Ultrafast electron diffraction allows the tracking of atomic motion in real time, but space charge effects within dense electron packets are a problem for temporal resolution. Here, we report on time-resolved

Electron diffraction by vacuum fluctuations

New Journal of Physics, 2020
Vacuum fluctuations are known to produce electron diffraction leading to decoherence and self-interference. These effects have so far been studied as either an extension of the Aharonov–Bohm effect in front of a planar perfect conductor or through path ...

3D electron diffraction goes multipolar. [PDF]

IUCrJ
Over 30 years ago, it was shown that bonding between atoms has a noticeable effect on convergent beam electron diffraction patterns. The paper by Olech et al. [(2024).

3D Electron Diffraction: The Nanocrystallography Revolution [PDF]

ACS Central Science, 2019
Crystallography of nanocrystalline materials has witnessed a true revolution in the past 10 years, thanks to the introduction of protocols for 3D acquisition and analysis of electron diffraction data. This method provides single-crystal data of structure solution and refinement quality, allowing the atomic structure determination of those materials ...

High-repetition-rate ultrafast electron diffraction with direct electron detection. [PDF]

Struct Dyn
Ultrafast electron diffraction (UED) instruments typically operate at kHz or lower repetition rates and rely on indirect detection of electrons. However, these experiments encounter limitations because they are required to use electron beams containing a

Electron Diffraction by Vapours [PDF]

Nature, 1933
DURING the last two years, a practical method has been evolved for obtaining good photographs of the diffraction of 30–55 kv. electrons by vapours. I now get satisfactory results with any substance the vapour pressure of which exceeds 10 cm. of mercury at 750° C.

Reaching the potential of electron diffraction. [PDF]

Cell Rep Phys Sci
Microcrystal electron diffraction (MicroED) is an emerging structural technique in which submicron crystals are used to generate diffraction data for structural studies. Structures allow for the study of molecular-level architecture and drive hypotheses about modes of action, mechanisms, dynamics, and interactions with other molecules.

Relativistic ultrafast electron diffraction at high repetition rates. [PDF]

Struct Dyn, 2023
The ability to resolve the dynamics of matter on its native temporal and spatial scales constitutes a key challenge and convergent theme across chemistry, biology, and materials science.

Multi-objective Bayesian active learning for MeV-ultrafast electron diffraction. [PDF]

Nat Commun
Ultrafast electron diffraction using MeV energy beams(MeV-UED) has enabled unprecedented scientific opportunities in the study of ultrafast structural dynamics in a variety of gas, liquid and solid state systems.
