Visualization of structural details of specimens in field emission scanning electron microscopy (FE-SEM) requires optimal conductivity. This paper reports on the differences in conductive layers of Au/Pd, Pt and Cr, with a thickness of 1.5–3.0 nm, deposited by planar magnetron sputtering devices. The coating units were used under standard conditions for source–substrate distance, current, HT an...

Fe-Ni alloys, which are kamacite (<10 wt% Ni), taenite (30 ~ 40 wt % Ni), and tetrataenite (ordered Fe 50 Ni 50), are the dominant magnetic minerals in the metamorphic (type 5-6) ordinary chondrites [1], and the carrier of the remanent magnetization is high coercivity tetrataenite [1,2,3]. Metallographic studies reported that there are two types of Fe-Ni grains in the metamor-phic ordinary chon...

Highly ordered, vertically oriented Fe3+-doped TiO₂ nanotube arrays (Fe-TNTs) were prepared on Ti-Fe alloy substrates with different Fe contents by the electrochemical anodization method. The as-prepared Fe-TNTs were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and related electrochem...

Recent developments in SEM column design have led to the ability to produce nm spot sizes even at high probe currents [1], thus pushing the analytical techniques available in the SEM to conduct microanalysis with nanometer resolution. Although the limitations of microanalysis at these spatial resolution requirements stem from the physics of beam-specimen interaction and the volume from which th...

To improve the electromagnetic characteristics of conductive nano fillers, carbon nanofibers (CNFs) with nickel-phosphorous (Ni-P) and nickeliron (Ni-Fe) have been fabricated by the electroless plating process. Observations by the electron microscopy (SEM/TEM) and element analyzer (EDS/ELLS) showed the uniform Ni-P and Ni-Fe coated CNFs. The compositions of the plating layers were about Ni-6wt%...
