Cryo field emission scanning electron microscopy.
Low-temperature scanning electron microscopy (cryoSEM) was introduced in the early 1970s, shortly after the appearance of the first commercial scanning electron microscopes. This technique has been utilized widely in plant biology, the food and paper industry, X-ray analytical studies, and material sciences (8). Major advantages of cryoSEM include being able to avoid deleterious changes associa...
متن کاملScanning Electron Microscopy (SEM) analysis and biological control of Ixodes ricinus using entomopathogenic fungi
In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...
متن کاملSecondary Electron Trajectories in Scanning Tunneling Microscopy
The recently developed technique Scanning Tunneling Microscopy in the Field Emission regime (STM FE) is based on the Russell Young's topografiner technology [1]. The set-up is a no contacting device consisting of a sharp tip approached vertically to a conducting surface at variable distances and biased with a small voltage with respect to the surface (Figure 1). The system builds a junction acr...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...
متن کاملPossible weak temperature dependence of electron dephasing
The first-principle theory of electron dephasing by disorder-induced two state fluctuators is developed. There exist two mechanisms of dephasing. First, dephasing occurs due to direct transitions between the defect levels caused by inelastic electron-defect scattering. The second mechanism is due to violation of the time reversal symmetry caused by time-dependent fluctuations of the scattering ...
