Observation on Fiber Surface by Scanning Electron Microscope

the scanning electron microscope

it is only thirteen years since the scanning electron microscope has been available commercially. yet, even in this short period of time, this instrument has been a powerful tool in the investigation of topography, electrical and magnetic properties, crystal structure, cathodoluminescent characteristics etc. of solid specimens. today, this type of microscope has opened its place alongside the c...

Application of Environmental Scanning Electron Microscope-Nanomanipulation System on Spheroplast Yeast Cells Surface Observation

The preparation and observations of spheroplast W303 cells are described with Environmental Scanning Electron Microscope (ESEM). The spheroplasting conversion was successfully confirmed qualitatively, by the evaluation of the morphological change between the normal W303 cells and the spheroplast W303 cells, and quantitatively, by determining the spheroplast conversion percentage based on the OD...

Observation of semiconductor elements using scanning electron microscope.

[A scanning electron microscope observation of Dictyocaulus filaria.].

In this study, D. filaria causing parasitic bronchopneumonia in sheep was observed using a scanning electron microscope. This parasite belongs to the Trichostrongyloidea super family. The oral opening of D. filaria was observed to be small and circular in shape. Lips were not evident. Any difference between anterior ends of male and female parasites was not observed in present study. In the fem...

scanning electron microscope (sem) evaluation of composite surface irradiated by different powers of er:yag laser

introduction: the aim of this study was to evaluate the composite surface treated by different powers of erbium-doped yttrium aluminum garnet (er:yag) laser in comparison with bur preparation via scanning electron microscope. methods: fourteen composite resin blocks with 15× 10 × 10 mm dimensions were used in this study. the samples were divided to seven groups as follow: group 1 (power: 1 w, e...
