SEM and optical energy

TiO2/CuSe nanocomposites were synthesized using a straightforward wet chemical without any sophisticated template. A variety of characterization techniques, including XRD, Raman spectra, UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), and SEM/EDS analysis were used to elucidate the structure, morphology, and optical properties of the TiO2/CuSe nanocomposite.

This article reports a novel and low temperature (275
C) synthesis of one-dimensional (1D) NWs of ZnTe on glass substrate. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive x-ray analysis (EDX) revealed that prepared NWs have good crystallinity and yield.

This paper assessed influence of dilution on the microstructure, mechanical properties and microhardness of a cobalt-based alloy deposited by plasma transferred arc (PTA) on three steel substrates. Dilution was analyzed by energy dispersive spectroscopy (EDS). Microstructure was analyzed by the optical microscopy (OM) and scanning electron microscopy (SEM). Microhardness measured on the scross section of coatings. Analysis results show that, the dilution ratio, microstructure and microhardness of the coating influenced by the welding parameters and substrates.

The dTGA curves show three different steps of weight loss. This is due to the loss of water adsorbed, the elimination of the side chains, and the decomposition of the main chain. For LiClO4 filled PVA/MAA:EA, FTIR spectra showed disappearance of some bands with the change in their intensities as compared to pure PVA/MAA:EA film.

A solid acid membranes based on poly (vinyl alcohol) (PVA), sodium bromide (NaBr) and phosphoric acid (H3PO4) were prepared by a solution casting method. The morphological, IR, electrical and optical properties of the (PVA)0.7(NaBr)0.3(H3PO4)xM solid acid membranes where x = 0.00, 0.85, 1.7, 3.4, 5.1 M were investigated. The variation of film morphology was examined by scanning electron microscopy (SEM) studies. FTIR spectroscopy has been used to characterize the structure of polymer and confirms the complexation of phosphoric acid with host polymeric matrix.

Polyaniline–NiFe2O4 nanocomposites (PANI–NiFe2O4) with different contents of NiFe2O4 (2.5, 5 and 50 wt%) were prepared via in situ chemical oxidation polymerization, while the nanoparticles nickel ferrite were synthesized by sol–gel method. The prepared samples were characterized using some techniques such as Fourier transforms infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Moreover, the electrical conductivity and optical properties of the nanocomposites were investigated. Pure (PANI) and the composites containing 2.
