Although bone minerals have been widely studied by various techniques in previous studies, crystal structures, morphology of bone minerals and its building pathway remained still controversy. In this work, the ultrastructure of the mineralization front of rabbit femur has been studied by conventional and high‐resolution (HR) transmission electron microscopy (TEM). In order to induce a healing and...
Scanning electron microscopy/energy dispersive X‐ray spectrometry (SEM/EDS) is a widely applied elemental microanalysis method capable of identifying and quantifying all elements in the periodic table except H, He, and Li. By following the “k‐ratio” (unknown/standard) measurement protocol development for electron‐excited wavelength dispersive spectrometry (WDS), SEM/EDS can achieve accuracy and precision...
Focused ion beam nanotomography‐scanning electron microscopy tomography yields high‐quality three‐dimensional images of materials microstructures at the nanometer scale combining serial sectioning using a focused ion beam with SEM. However, FIB‐SEM tomography of highly porous media leads to shine‐through artifacts preventing automatic segmentation of the solid component. We simulate the SEM process...
A number of techniques have been proposed during the last three decades for noise variance and signal‐to‐noise ratio (SNR) estimation in digital images. While some methods have shown reliability and accuracy in SNR and noise variance estimations, other methods are dependent on the nature of the images and perform well on a limited number of image types. In this article, we prove the accuracy and the...
The methodology for fracture analysis of polymeric composites with scanning electron microscopes (SEM) is still under discussion. Many authors prefer to use sputter coating with a conductive material instead of applying low‐voltage (LV) or variable‐pressure (VP) methods, which preserves the original surfaces. The present work examines the effects of sputter coating with 25 nm of gold on the topography...
One‐dimensional Nylon6 nanofibers were fabricated through the electrospinning process. The effect of the applied electric field and voltage–distance combinations on the diameter and size distribution of the fibers was examined systematically by analyzing scanning electron microscopy (SEM) images. The results indicated that maintaining the electric field at 1 kV/cm with the voltage–distance combination...
