Event-responsive scanning transmission electron microscopy
ScienceAn 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, 1978Our 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, 1980The 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, 1975The 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, 1986Electron 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.

Scanning transmission electron microscopy of thin specimens
Ultramicroscopy, 1976The intensity distributions in bright field and dark field images of thin specimens obtained in scanning transmission electron microscopy are evaluated in terms of the phase of object approximation for coherent and partially coherent illumination.
