The abTEM code: transmission electron microscopy from first principles

Open Research Europe, 2021
Simulation of transmission electron microscopy (TEM) images or diffraction patterns is often required to interpret experimental data. Since nuclear cores dominate electron scattering, the scattering potential is typically described using the independent ...

Analytical Transmission Electron Microscopy [PDF]

Reviews in Mineralogy and Geochemistry, 2014
Analytical transmission electron microscopy (TEM) is used to reveal sub-micrometer, internal fine structure (the microstructure or ultrastructure ) and chemistry in minerals. The amount and scale of the information which can be extracted by TEM depends critically on four parameters; the resolving power of the microscope (usually smaller than 0.3 nm ...

Stability and activity of platinum nanoparticles in the oxygen electroreduction reaction: is size or uniformity of primary importance?

Beilstein Journal of Nanotechnology, 2021
Platinum–carbon catalysts are widely used in the manufacturing of proton-exchange membrane fuel cells. Increasing Pt/C activity and stability is an urgent task and the optimization of their structure seems to be one of the possible solutions.

Hunting coronavirus by transmission electron microscopy – a guide to SARS‐CoV‐2‐associated ultrastructural pathology in COVID‐19 tissues

Histopathology, 2020
Transmission electron microscopy has become a valuable tool to investigate tissues of COVID‐19 patients because it allows visualisation of SARS‐CoV‐2, but the ‘virus‐like particles’ described in several organs have been highly contested.
