Field emission scanning electronic

A Dektak siuface profilometer was used to measure the etch rates. The profiles of the etched films were observed by field emission scanning electron microscopy (FESEM). In addition, x-ray photoelectron spectroscopy PCPS) was utilized to examine the existence of possible etch products or redeposited materials, and to elucidate the etch mechanism of Co2MnSi magnetic films in a CVOa/Ar plasma.

Image analysis has been used to characterize the pore structure of synthetic membrane materials. The Celgard films have also been characterized by scanning tunneling microscopy, atomic force microscopy, and field emission scanning electron microscopy. The pore size of the Celgard membranes can also be calculated from eq 5, once the MacMullin number and gurley values are known. 

The morphology of silver nanopartilces on the cotton surface and paint samples was observed by field emission scanning electron microscopy (FE-SEM JSM-6700F, JEOL, Japan). The size and shape of the nanoparticles in solution were determined with transmission electron microscopy (TEM) (LEO-912-OMEGA, Carl Zeiss, Germany).

Enhanced imaging of several dairy products has been demonstrated through the application of a relatively elaborate preparative technique in combination with a cold-field emission scanning electron microscope (FESEM) [86], The preparative methods include a metal-impregnation technique, termed tannin-ferrocyanide-osmium (TA-F-O, Figure 21), which was adapted from Hirano et al. [87].

I was characterized by powder X-ray diffraction (PXRD), energy dispersive analysis of X-rays (EDAX), chemical analysis, thermogravimetric analysis (TGA) and IR spectroscopy. EDAX analysis indicated the ratio of Mn S to be 3 2. The presence of fluorine was confirmed by analysis and the percentage of fluorine estimated by EDAX in a field emission scanning electron microscope was also satisfactory. Thermogravimetric analysis also confirms the stoichiometry of the compound. Bond valence sum calculations6 and the absence of electron density near fluorine in the difference Fourier map also provide evidence for the presence of fluorine. The sulfate content was found to be 30.8% compared to the expected 32% on the basis of the formula.
