The High Voltage Electron Microscope in Biology
The first published micrograph of a biological specimen photographed in a high voltage electron microscope (HVEM) appeared in a paper by Van Dorsten et al. in 1947, and it is consequently surprising that the HVEM does not play a greater role in biology 27 yr later. There are various reasons for this. The first prototypes were developed with the aim of enabling the investigator to examine thicke...
متن کاملTelecontrol of Ultra-High Voltage Electron Microscope over Global IPv6 Network
Osaka University has an Ultra-High Voltage Electron Microscope (UHVEM) which can provide high quality specimen images for worldwide researchers. For usability improvements, we have worked on the telecontrol of the UHVEM. In this paper, we would like to introduce a part of our activities on the telecontrol of the UHVEM. In order to remotely control the microscope, we must provide high quality dy...
متن کاملElectron beam excitation assisted optical microscope with ultra-high resolution.
We propose electron beam excitation assisted optical microscope, and demonstrated its resolution higher than 50 nm. In the microscope, a light source in a few nanometers size is excited by focused electron beam in a luminescent film. The microscope makes it possible to observe dynamic behavior of living biological specimens in various surroundings, such as air or liquids. Scan speed of the nano...
متن کاملChoice of operating voltage for a transmission electron microscope.
An accelerating voltage of 100-300kV remains a good choice for the majority of TEM or STEM specimens, avoiding the expense of high-voltage microscopy but providing the possibility of atomic resolution even in the absence of lens-aberration correction. For specimens thicker than a few tens of nm, the image intensity and scattering contrast are likely to be higher than at lower voltage, as is the...
متن کاملA Stereoscope Observation of Tracheal Epithelium of Mouse by Means of the High Voltage Electron Microscope
The tracheal epithelium of the rodent is a simple columnar ciliated type composed of ciliated cells, goblet cells, nonciliated columnar cells, brush cells, and basal cells. The noncillatcd cells are concells have been described in detail (Rhodin and Dalhamn, 1956; Rhodin, 1966; Leeson, 1961; Cireli, 1966; Steinman, 1968), the three-dimensional construction of the tracheal epithelimn has never b...
