Analysis and applications of a heralded electron source

New Journal of Physics
We analytically describe the noise properties of a heralded electron source made from a standard electron gun, a weak photonic coupler, a single photon counter, and an electron energy filter.

Efficient diffractive phase optics for electrons

New Journal of Physics, 2014
Electron diffraction gratings can be used to imprint well-defined phase structure onto an electron beam. For example, diffraction gratings have been used to prepare electron beams with unique phase dislocations, such as electron vortex beams, which hold ...

Aberration correction for low voltage optimized transmission electron microscopy

MethodsX, 2018
Further development of low voltage electron microscopy leads to an aberration correction of the device in order to improve its spatial resolution. The integration of a corrector to a desktop transmission electron microscope with exclusively low-voltage ...

Preparation of Candida albicans Biofilms for Transmission Electron Microscopy

Bio-Protocol, 2013
Transmission Electron Microscopy is a form of microscopy that allows for imaging of distinct portions of an individual cell. For Candida albicans biofilms, it is often used to visualize the cell walls of fixed samples of yeast and hyphae.

Transmission Electron Microscopy (TEM) Protocol: Observation Details within Cells

Bio-Protocol, 2013
Transmission electron microscopy is a technique for observing the fine details of organelles in cells or tissues. This protocol is to be used to exam the membrane structure in cells with or without virus infection.

Examining Autophagy in Plant by Transmission Electron Microscopy (TEM)

Bio-Protocol, 2018
In plants, macroautophagy, here referred as autophagy, is a degradation pathway during which the double-membrane structure named autophagosome engulfs the cargo and then fuses with vacuole for material recycling.

Transient alumina transformations on Ni–Cr–Al alloys: nanocrystallization and Cr concentration impacts

Journal of Materials Research and Technology
Ni–Cr–Al coarse-grained (CG) or nanograined (NC) alloys with 5 wt% Al but various Cr concentrations (10 wt% and 30 wt%) were prepared via casting and magnetron sputtering, respectively.

ELECTRON TRANSMISSION MICROSCOPY

Le Journal de Physique Colloques, 1974
The purpose of this short lecture is to explain why defects are imaged in the electron microscope, and to emphasize that a good understanding of the theory can lead to important informations about the defects. First, the different notions and parameters describing the diffraction of electrons by a perfect foil are introduced and discussed to some ...
