Polymer Sample Preparation for Electron Microscopy

Transmission Electron Microscopy Sample Preparation of INCONEL 738 Nickel-Base Superalloy

Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...

Sample preparation for STED microscopy.

Since the discovery of the diffraction barrier in the late nineteenth century, it has been commonly accepted that with far-field optical microscopy it is not possible to resolve structural details considerably finer than half the wavelength of light. The emergence of STED microscopy showed that, at least for fluorescence imaging, these limits can be overcome. Since STED microscopy is a far-fiel...

Specimen Preparation for Electron Microscopy

In general the SEM sample preparation techniques are more or less similar to the metallographic sample preparation technique for optical microscopy, because both the microscopes reveals the surface topography of sample. In SEM a focussed beam of electrons scans over the specimen surface and the electrons emitted from the sample surface controls the brightness of the CRT spot which also scans th...

Preparation of Microorganisms for Electron Microscopy.

Preparation of Dictyostelium discoideum for electron microscopy.

Dictyostelium discoideum grew and differentiated normally on cellulose dialysis membranes placed on agar plates. This permitted the examination of cells at various stages of development, including cells during aggregation. Cells were preserved well and fixed for electron microscopy by brief exposure to acrolein vapore followed by immersion in glutaraldehyde solution.
