Machine learning for automated experimentation in scanning transmission electron microscopy

open access: yesnpj Computational Materials, 2023
Machine learning (ML) has become critical for post-acquisition data analysis in (scanning) transmission electron microscopy, (S)TEM, imaging and spectroscopy. An emerging trend is the transition to real-time analysis and closed-loop microscope operation.

Scanning transmission electron microscopy* [PDF]

open access: yesJournal of Microscopy, 1974
SUMMARYThe scanning transmission electron microscope is of quite recent origin, and it is only in the last few years that it has been shown that this instrument is capable of giving the same high resolution as the conventional electron microscope. In this article we examine the conditions necessary for the achievement of high resolution and also the ...

Does drying affect gel networks? [PDF]

open access: yes, 2018
The properties of low molecular weight gels are determined by the underlying, self-assembled network. To access information on the network, it is common for techniques to be used that require the gel to be dried, such as transmission electron microscopy ...
