Characterization of mouse spermatogonia by transmission electron microscopy

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Visualization and characterization of receptor clusters by transmission electron microscopy.

Multivalency is a feature common to many natural glycoconjugates, including glucosaminoglycans, mucins, and lipopolysaccharides. Multivalent ligands often bind avidly to their target receptors. In addition, they can simultaneously bind multiple receptors and cause them to become clustered (Fig. 1). Receptor clustering by multivalent ligands modulates the cell adhesion and signaling functions of...

Characterization of the cell-nanopillar interface by transmission electron microscopy.

Vertically aligned nanopillars can serve as excellent electrical, optical and mechanical platforms for biological studies. However, revealing the nature of the interface between the cell and the nanopillar is very challenging. In particular, a matter of debate is whether the cell membrane remains intact around the nanopillar. Here we present a detailed characterization of the cell-nanopillar in...

Defects characterization of welded specimens by transmission electron microscopy

Austenitic Type 304L stainless steel (SS) and martensitic Alloy EP-823 have been identified as candidate structural materials to contain spallation arget for transmutation of nuclear waste. Welded specimens consisting of either or both materials have been evaluated by transmission electron icroscopy (TEM) to determine the dislocation density near the heat-affected-zone (HAZ) and the base materi...
