Field emission-scanning electron microscope

Typical examples of Rutherford-scattered imaging of nanoparticles of a commercially important Pd/C catalyst recorded with (a) a BSE detector in a field emission scanning electron microscope as well as (b) a STEM HAADF image of the same 5% Pd/C sample, recorded in the same instrument, are shown...

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.

Are carbynes produced in laboratory carbon and C IC Ar vapors designed to simulate the properties carbon dust in astrophysical environments Field-emission scanning electron microscope (FESEM) and HRTEM studies of vapor-condensed carbon smokes showed a wide range of carbon morphologies that were free of metal impurities (at EDS detection limits), viz. 1. Ceo and higher fullerenes that agglomerated into amorphous soot grains, 2. fullerenic nanotubes and onions, 3. amorphous carbon sheets,... 

Characterization method SEM was carried out on a Zeiss DMS 982 Gemini field emission scanning electron microscope at 4.0 kV. TEM was performed using a JEOL 21 OOF electron microscope operated at 200 kV. The UV/Vis absorption spectra were measured using a Shimadzu UV-I650PC spectrophotometer. N2 adsorption-desorption isotherms were obtained on Nova 2000 pore analyzer at 77 K under continuous adsorption condition. The ionic concentration of the solution was analyzed by inductively coupled plasma atomic emission spectroscopy (ICP-AES Varian Co., USA). 

X-ray diffraction (XRD) patterns were measured by a PHILIPS X Pert Pro. diffractometer using Cu Ka radiation (7. = 0.154 nm). The morphologies of all mentioned samples were observed by a field emission scanning electron microscope (SEM, JSM- 6700F).

SEM is used to probe microstructural features from 10 nm- 1 tim A Field Emission Scanning Electron Microscope (FESEM) allows imaging of many non-conductive materials at relatively low voltages (200 eV - 30 keV) witiiout applying a conductive coating. An energy dispersive x-ray spectrometer (EDS)... 

Phase purity, ciystallite size, morphology, specific surface area, and elemental composition of the sol-gel derived ferrite powders were analyzed using a Panalytical XPert MPD/DY636 powder X-ray diffractometer, a Zeiss Supra 55 VP field-emission scanning electron microscope (SEM), a FEI -Tecnai G2 200kV transmission electron microscope (TEM), a BET surface area analyzer (Micromeritics, ASAP 2420), and an ICP (Thermo, iCAP 6500). 

The Ag nanorods were characterized according to morphology, crystal stmcture, optical properties, and SERS activity. The size, shape, and spacing of the nanorods were determined with a LEO 982 field emission scanning electron microscope (SEM) (Thomwood, NY).
