Scanning Electron Microscopy with Polarization Analysis (sempa) and Its Applications
Scanning Electron Microscopy with Polarization Analysis (SEMPA) is a technique for directly imaging the magnetic microstructure of surfaces and thin films. SEMPA relies on the fact that secondary electrons emitted from a magnetic sample in a Scanning Electron Microscope (SEM) have a spin polarization which reflects the net spin density in the material. This spin density, in turn, is directly re...
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 کاملNano-Structure Roughening on Poly(Lactic Acid)PLA Substrates: Scanning Electron Microscopy (SEM) Surface Morphology Characterization
Scanningelectron microscopy (SEM) has been utilized to examine the morphology and topography alterations in the surface of Poly(Lactic Acid)(PLA) fabrics due to UV/Ozoneirradiation. In the past decade, a growing attention in the usage of “Green Techniques” in industrial applications has been observed owing to many benefits such as low impurities and their relatively low cost to substitute th...
متن کاملSpin-polarized Scanning Electron Microscopy for Analysis of Magnetic Devices
Spin-polarized scanning electron microscopy (spin SEM) is a method, which measures spin polarizations of secondary electrons, for observing magnetic domains. The main characteristics of spin SEM images are high spatial resolution, topography independency, and the capability of magnetization vector analysis in three dimensions. Taking advantages of these characteristics, spin SEM is expected to ...
متن کاملComparison of Aerobic Sporadic Bacilli Structure with Electron Microscopy
I. The existence of differences and similarities in the sur- 4. face features not only of different organisms or groups but also within given species has been demonstrated by a variety of techniques. 2. The different reactions of various organisms to the Gram stain might well be taken as one piece of evidence, the use of the electron microscop and associated preparative techniques (includi...
