Scanning electron microscope

Results and discussions: The structure of the prepared material was investigated employing many techniques such as X-rays diffraction, SEM and TEM electron microscopy. In order to scrutinize the crystal structure of the samples X-rays diffraction was carried out using diffractometer XPERT-MPDUG, Philips PW3040. Figure (1) depicts the X-ray diffraction of the as synthesized samples. It can be seen that the nature of the sample is formed in poly crystalline form. The most important peaks are displayed

Semi-organic nonlinear optical materials are receiving a great deal of attention, as they have large optical susceptibilities, inherent ultra fast response times and high optical thresholds for laser power compared with inorganic materials. In the present investigation, a systematic study has been carried out on the growth of pure and doped Tetrafluoro Phthalate crystals. The lattice parameters find through Powder X-ray diffraction analysis for the grown pure and doped crystals. The functional

6-dimethyl-2-pyridineselenol-3-caronitrile and 4-Methylquinolineselenol- 3-carbonitrile as models for organoselenium compounds. The size and the catalytic performance of the prepared fluorescent nanoclusters were characterized using suitable Transmission Electron Microscope (TEM), Atomic Force Microscopy (AFM), Electrospray Ionization-Mass Spectrometry (ESI-MS) and photoluminescence techniques. It is shown that Au clusters with an average diameter of gold core 0.78 ± 0.41 nm (in the range of 5-9 atoms), have a

They cost 75 dollars per square foot. Quartz is made of silicon and oxygen atoms. On the Mohs scale it is 7 for hardness. The category it is under is oxide mineral. The crystal structure is trigonal. The Chemical formula is SiO2. The luster is vitreous, waxy, dull. The streak color is white. The fracture is conchoidal. Quartz is found in all types of rocks igneous, metamorphic and sedimentary. Quartz is resistant to weathering. White sands are the easiest way to find quartz in the sand. There is

Also, group 2 data was missing, we can estimate the value should be between Group 1 and 3. And I fixed the value at the same initial point, so we can see the change more directly. As it shown to us above, with the boron composition increasing, the solubility is decreasing. Conclusion From XRD we can get the glass is partially glass and partially crystalline. EDS shows the element composition of the glass, and the SEM pictures show us the microscopy image of the glass, and we can find a lot of crack

Investigation of in vitro and in vivo antifungal activity of different plant acetonic extracts against fungal skin isolates ABSTRACT T he worldwide increase of multidrug resistance has impaired the current antimicrobial therapy, warranting the search for other alternatives.This study investigated the efficacy of using plant extracts; Lawsonia inermis L(Henna), Glycyrrhiza glabra L(licorice) and Rosmarinus officinalis L (Rosemary) as antifungal agents.Antifungal susceptibility test revealed that nystatin

of 20°-80° [Bruker Advanced-D8 powder X-ray diffractometer]. The scanning speed and steps were 2°/ minute and 0.02° of 2θ respectively. The XRD data were analyzed by Rietveld refinement technique using FULLPROF program to confirm the phase formation as well as to obtain the lattice parameters, space group and crystal system [2]. The microstructures and crystal structures of the nanoparticles were obtained using Transmission Electron

(Novoselov et al, 2004, Yang et al, 2008). Graphene has unique hierarchical and physicochemical properties including a high surface area (2630 m2/g), extraordinary electrical and thermal conductivity (mobility: 20,000 cm2V-1 s-1) through the pie electron cloud makes graphene a promising material in conducting composites and quantum electronics (Bolotin et al, 2008, Morozov et al, 2008) and also possess strong mechanical strength (~1100 Gpa (Lu et al,

from beginning of testing to the end of testing and the change in diameter was calculated. Polymer degradation time (mass loss) will be collected for 0, 1, 2, 3, 4, 6, 8, 12 weeks from the initial mass before degradation and the residual mass. Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and optical micrograph will be used to observe scaffold and collagen fibers morphology for 0, 3, 6, 12 wk31, 35. These methods can also measure fiber size and shape as well as the diameter and thickness

The formation of nanocrystalline ZnO films was confirmed by using X-ray diffraction. XRD patterns of simple glass substrate and ZnO coated glass substrates were shown in figure 3(a) and (b-d), respectively. The amorphous behavior of glass substrate with a continuous curve ~20˚ to 35˚ in 2θ range was depicted in ‘figure 3(a)’ and was clearly evidenced in ZnO coated substrates. A comparatively low intensity and broadness in diffraction peaks was observed in single layer deposited ZnO thin film ‘figure
