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 ...

Scanning and Transmission Electron Microscopy of Calcified Tissues*,†

Biomaterials, Medical Devices, and Artificial Organs, 1975
Some recent innovations have been utilized to extend studies of the structure of calcified tissues on the ultra- and microstructural levels of organization. The introduction of hydrazine as a replacement for the conventionally used ethylene diamine to deproteinize calcified tissue samples has resulted in the acquisition of previously unobtainable ...

Scanning and transmission electron microscopy of the rat kidney

American Journal of Anatomy, 1974
AbstractThis study utilized scanning and transmission electron microscopy of renal tissue to provide new information on the gross and microscopic structure of the kidney. The luminal surface of the proximal convoluted tubule was characterized not only by the border of microvilli, but also by crater‐like depressions, and circumferential folds. In tissue

Spot-Scan Imaging in Transmission Electron Microscopy

Science, 1991
The determination of the structure of proteins and other organic materials by transmission electron microscopy is a rapidly developing field. Obtaining high-resolution images of these radiation-sensitive specimens has, until recently, been problematic. The development of spot-scan imaging, in which the electron beam is focused to a spot with a diameter

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.
