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.

Event-responsive scanning transmission electron microscopy

Science
An ever-present limitation of transmission electron microscopy is the damage caused by high-energy electrons interacting with any sample. By reconsidering the fundamentals of imaging, we demonstrate an event-responsive approach to electron microscopy that delivers more information about the sample for a given beam current. Measuring the time to achieve

Scanning transmission electron microscopy of biological macromolecules

Ultramicroscopy, 1978
Our aim is to use Scanning Transmission Electron Microscopy (STEM) for research on biological macromolecules. Preliminary experiments have been carried out on a Philips EM 300 (equipped with a high resolution stage and normal hairpin cathode) with a STEMattachment.

Scanning transmission electron microscopy of biological macromolecules

Ultramicroscopy, 1980
The practical usefulness of a STEM (Scanning Transmission Electron Microscope) for the study of the structure of biological macromolecules has been investigated using a STEM attachment connected to a TEM (Transmission Electron Microscope), which in one case was equipped with a tungsten hairpin cathode, and in the other case with a field emission gun ...

Scanning and transmission electron microscopy of odontogenic keratocysts

Oral Surgery, Oral Medicine, Oral Pathology, 1975
The ultrastructural characteristics of the superficial cells of the epithelial lining of odontogenic keratocysts were studied. Examples of both the parakeratinized type and the less common orthokeratinized variant were examined. Scanning electron microscopy reveals that the morphology of the two cyst types is distinctly different.

Transmission and Scanning Electron Microscopy of Peripheral Nerves

Hand Clinics, 1986
Electron microscopy of peripheral nerve tissue by SEM and TEM facilitates a better understanding of the complex nerve architecture described by early light microscopists. Details of axonal morphology and the Schwann cell/myelin sheath complex in healthy and diseased nerves have been described in the literature.
