Abstract Graphene oxide (GO) thin films were prepared successfully using modified Hummer’s method, which includes oxidation of graphite and reduction to graphene at room temperature. Then; the samples deposited on glass substrates sol-gel technique. Different solutions have been used obtain such as Ethanol, Acetone, Deionized Water. The structural, optical electrical properties diagnosed studied microscope XRD diffraction, Fourier Transform Infrared Spectroscopy (FTIR) UV-Vis...
Abstract Image analysis took wide areas in many fields, including medicine, physics, and other where you need a tool to deal with it smoothly softly without losing the original image information. Using an of sample physical atom that was analyzed highlighting compression raising noise, histogram statistics best results were recorded when using specific threshold i.e. pressing methods used first has is Balance sparsity-norm, Remove near 0 Bal-sparsity-norm(sqrt). As for noise are fixed form...
Abstract To purify water at low cost for our daily life, the effect of ceramic-based (mullite–cristobalite) and (mullite–zircon) powders doped with different amounts magnesium oxide (MgO) (10 20 wt%) was studied. These compounds are made a local raw material DD3 addition zirconia (ZrO 2 ) to create an open porosity. The were prepared by traditional mixing method help automated crushing. MgO doping on structural, morphological photocatalytic properties studied various analytical techniques...
In this paper, we present an intensive investigation of the finite volume method (FVM) compared to difference methods (FDMs). order show main in way approaching solution, take Burgers equation and Buckley–Leverett as examples simulate previously mentioned methods. On one hand, results using schemes Lax–Friedrichs Lax–Wendroff. other apply Godunov’s scheme method. Moreover, how starting with a variational formulation problem, element technique provides piecewise formulations functions defined...
A solid-state reaction technique was used to synthesize polycrystalline Na2WO4. Preliminary X-ray studies revealed that the compound has a cubic structure at room temperature. The formation of been confirmed by powder diffraction and Raman spectroscopy. Electrical dielectric properties have studied using complex impedance spectroscopy in frequency range 209 Hz-1 MHz temperature 586-679 K. data were modellized an equivalent circuit consisting series combination grains boundary. We use...
