Forensic Applications of the 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...

Cell organelles at uncoated cryofractured surfaces as viewed with the scanning electron microscope.

A method of direct visualization of cell organelles by scanning electron microscopy (SEM) is described. Plant and animal tissues fixed in glutaraldehyde and osmium tetroxide are treated with the ligand thiocarbohydrazide and a second osmium tetroxide solution, to increase their osmium content. Tissues are then dehydrated, infiltrated with an epoxy monomer, and together solidified with dry ice a...

Semiautomatic classification of cementitious materials using scanning electron microscope images

Segmentation and classification are prolific research topics in the image processing community, which have been more and more used in the context of analysis of cementitious materials, on images acquired with Scanning Electron Microscopes (SEM) . Indeed, there is a need to be able to detect and to quantify the materials present in a cement paste in order to follow the chemical reactions occurri...
