Scanning Transmission Electron Microscopy

2015
The scanning transmission electron microscope (STEM) is one of the most useful tools in many areas of atomic-scale materials science and nanocharacterization. A STEM has the ability to generate local maps of the chemical composition and electronic structure at atomic resolution, even in complex or unknown samples.

Scanning Electron Microscopy of Trematodes Embedded for Transmission Electron Microscopy

The Journal of Parasitology, 1973
Chipping plastic from the surface of trematodes embedded for transmission electron microscopy permits high resolution scanning electron microscopy of surface features. The surfaces of the trematodes Megalodiscus temperatus, Diclidophora merlangi, and Schistosoma mansoni are described and comparisons are made with previous studies using the transmission

Automated electron tomography with scanning transmission electron microscopy

Journal of Microscopy, 2007
SummaryWe report the successful implementation of a fully automated tomographic data collection system in scanning transmission electron microscopy (STEM) mode. Autotracking is carried out by combining mechanical and electronic corrections for specimen movement. Autofocusing is based on contrast difference of a focus series of a small sample area.

Transmission and scanning electron microscopy of Besnoitia besnoiti

International Journal for Parasitology, 1988
Abstract Transmission electron microscopy of Besnoitia besnoiti cystozoites from a naturally infected bull revealed typical apicomplexan structures. The crescent-shaped parasite was enclosed by a pellicle comprised of one outer and two inner membranes.

Scanning transmission low-energy electron microscopy

IBM Journal of Research and Development, 2011
We discuss an extension to the transmission mode of the cathode-lens-equipped scanning electron microscope, enabling operation down to the lowest energies of electrons. Penetration of electrons through free-standing ultrathin films is examined along the full energy scale, and the contribution of the secondary electrons (SEs), released near the bottom ...

Scanning transmission electron microscopy of biological structures

Biology of the Cell, 1994
The design of the scanning transmission electron microscope (STEM) has been conceived to optimize its detection efficiency of the different elastic and inelastic signals resulting from the interaction of the high energy primary electrons with the specimen.

Fixation of Platelets for Scanning and Transmission Electron Microscopy

Stain Technology, 1977
A double fixation method of preparing platelet suspensions for both scanning and transmission electron microscopy is outlined. Prefixation in 0.1% glutaraldehyde allows for immediate preservation of morphologic characteristics induced by experimental procedures, but does not completely destroy platelet surface stickiness.

Scanning and Transmission Electron Microscopy of the Nasal Mucosa

Otolaryngologic Clinics of North America, 1977
We attempted to study the nasal mucosa of children (both normal and diseased) under light microscopy followed by both scanning and transmission electron microscopy. Combined methods of microscopy are valuable tools in establishing the diagnosis and lead to a better understanding of disease and its management.

Scanning Transmission Electron Microscopy

2018
Scanning transmission electron microscopy (STEM) (Pennycook, Nellist in Scanning Transmission Electron Microscopy, Imaging and Analysis. Springer, New York, 2011 [1]; Tanaka in Scanning Transmission Electron Microscopy of Nanomaterials. Imperial College Press, London, 2015 [2]) is a method of observing a small area using an incident electron probe ...

Phase-contrast scanning transmission electron microscopy

Microscopy, 2015
This report introduces the first results obtained using phase-contrast scanning transmission electron microscopy (P-STEM). A carbon-film phase plate (PP) with a small center hole is placed in the condenser aperture plane so that a phase shift is introduced in the incident electron waves except those passing through the center hole.
