Penetration and energy-loss theory of electrons in solid targets
Starting from a simple atomic model giving the potential between electrons and atoms as V(r) = Ze2as−1/srs with the empirical value s=fraction six-fifths, we combine the diffusion effect due to…
Three-dimensional analysis of morphogenesis induced by mating pheromone alpha factor in Saccharomyces cerevisiae.
Ultrastructural analyses of cytoplasmic changes in Saccharomyces cerevisiae X2180-1A (MATa) that had been treated with alpha factor were performed by using the freeze-substitution fixation method, showing a polar organization of the cy toplasm during projection formation.
Secondary electron emission due to primary and backscattered electrons
Based on a simple atomic model giving the potential between electrons and atoms as V(r)=Ze2as −1/srs, the range of electrons penetrating solid targets is derived. Starting from the generalized power…
Filamentous Structure in Yeast Mitochondria by Freeze-Etching of Replica Combined with Rapid Freezing
A digital processing method for the structural analysis of lattice images of crystalloids obtained by electron microscopy
The energy dependence of a diffusion model of an electron probe into solid targets
The penetration and energy loss characteristics of an electron probe with energies 1 and 103 keV in solid targets are analysed by using the potential function of the power and exponential forms of…
The structure analysis of Hirano bodies by digital processing on electron micrographs
It is proposed that the filaments of Hirano bodies are helical strands with a pitch of 185 Å and a model for the helical strand drawn by microcomputer at various angles of rotation is in accordance with the filtered images of the tilted filaments.
High resolution shadowing for electron microscopy by sputter deposition.
The conversion of a field‐emission scanning electron microscope to a high‐resolution, high‐performance scanning transmission electron microscope, while maintaining original functions
Recently, the reliability of field-emission electron guns has increased. In addition, the cost of computer systems for on-line processing has dropped. Hence, we should now consider the use of…
