Femtosecond single-electron diffraction [PDF]

open access: yesStructural 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 crystallography and dedicated electron-diffraction instrumentation

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2023
Electron diffraction (known also as ED, 3D ED or microED) is gaining momentum in science and industry. The application of electron diffraction in performing nano-crystallography on crystals smaller than 1 µm is a disruptive technology that is opening up ...

3D Electron Diffraction: The Nanocrystallography Revolution [PDF]

open access: yesACS 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 ...

X-ray crystal structure of cytotoxic oxidized cholesterols: 7-ketocholesterol and 25-hydroxycholesterol

open access: yesJournal of Lipid Research, 1997
The cytotoxic cholesterol derivative, 7-ketocholesterol, crystallizes in a monoclinic unit cell, space group P2(1) with a = 11.405 A, b = 6.288 A, c = 35.393 A and beta = 92.75 degrees (Z = 4).

Electron diffraction of tilted perovskites [PDF]

open access: yes, 2005
Simulations of electron diffraction patterns for each of the known perovskite tilt systems have been performed. The conditions for the appearance of superlattice reflections arising from rotations of the octahedra are modified to take into account ...

Structural determination and packing analysis of a cholesteryl caprate/cholesteryl laurate solid solution.

open access: yesJournal of Lipid Research, 1994
This paper describes the X-ray crystal structure analysis of a cholesteryl ester solid solution, cholesteryl decanoate/cholesteryl laurate, grown from a bulk concentration with molar ratio 0.56/0.43. The unit cell is monoclinic with a = 12.969, b = 9.048,

Single-Shot Electron Diffraction using a Cold Atom Electron Source [PDF]

open access: yes, 2015
Cold atom electron sources are a promising alternative to traditional photocathode sources for use in ultrafast electron diffraction due to greatly reduced electron temperature at creation, and the potential for a corresponding increase in brightness ...

Cholesteryl esters of saturated fatty acids: cosolubility and fractionation of binary mixtures

open access: yesJournal of Lipid Research, 1987
Factors affecting the solid state miscibility of saturated chain cholesteryl esters were determined from electron diffraction and differential scanning calorimetric measurements on a homologous series which included two types of crystal packing. Electron
