A dual stage process of depositing bamboo-like carbon nanotubes (BCNTs) by hot filament chemical vapor deposition (HFCVD) and coating Si using Radio frequency sputtering (RFS) technique. The films were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and electron field emission studies (EFE)....

nanocrystalline zinc oxide (zno) powders with different morphology have been successfully synthesized by using different surfactants such as cetyl trimethyl ammonium bromide (ctab), sodium dodecyl sulphate (sds), and tri ethanol amine (tea) via hydrothermal method. the products were characterized by means of powder x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electr...

Among the techniques of electron microscopy, scanning electron microscopy (SEM) represents a high-performance method of investigating structures and devices in the domain of nanometer dimensions. This paper is a synthesis of the possible applications of SEM in the investigation of the nanometer domain, nanomaterials and nanotechnologies.

New developments in scanning electron microscopy (SEM) have resulted in a wealth of new applications for cell and molecular biology as well as related biological disciplines. New instrument developments coupled with new sample preparation techniques have been key factors in the increasing popularity of this versatile research tool. The desire to view biological material in native states at high...

Rat liver sinusoidal endothelial cells (LEC) contain fenestrae, which are clustered in sieve plates. Fenestrae control the exchange of fluids, solutes and particles between the sinusoidal blood and the space of Disse, which at its back side is flanked by the microvillous surface of the parenchymal cells. The surface of LEC can optimally be imaged by by scanning electron microscopy (SEM), and SE...

Representative top-view scanning electron microscopy (SEM) images of (c) gold nanobumps from the same array and (f) corresponding gold nanocones. Insets (d-f) correspond to SHG and SEM images of a gold nanorod on the same substrate. SECOND-HARMONIC GENERATION MICROSCOPY OF INDIVIDUAL METAL NANOPARTI...

Electron Microscopy (EM) is an important viewing technique for the study of microorganisms. More specifically, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) are extremely useful tools for the ultrastructural examination of prokaryotic cells as well as for the study of the interaction between bacterial pathogens and host cells. Perhaps one of the most interesting ...
