Development of JEM-F200 (F2) Multi-Purpose Electron Microscope

Electron microscopy’s multi-tool: the Scanning Transmission Electron Microscope

A dedicated Scanning Transmission Electron Microscope is ideally coupled with the energy dispersive x-ray and electron energy loss spectroscopies to obtain information about the chemical composition, morphology and electronic structure on the nanoscale. With several signals being available simultaneously with the pass of a subnanometre-sized beam, this instrument can answer questions from a bro...

Development of Multi-Purpose Biological Reference Materials

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...

An Electron Microscope Study of the Development of Sv40 Virus

Kidney cells, predominantly from Cercopithecus monkeys but also from baboons, were infected in vitro with the SV40 virus. The infectious cycle was studied with the electron microscope by means of thin sections of cells fixed from 3 hours up to 11 days after infection. The frequency of virus formation and various nuclear and cytoplasmic lesions in relation to the infection are described. The vir...
