In the present work, TiO2 nanoparticle and multi-walled carbon nanotubes composite powder is prepared hydrothermally. After doctor blading the paste from composite powder, the resulted composite film is sensitized with Cu-based metal-organic frameworks using a layer-by-layer deposition technique and the film is characterized using FE-SEM, EDX, XRD, UV/Visible spectrophotometry and photoluminesc...

A preferentially oriented mordenite membrane was successfully prepared on a seeded porous a-alumina support. Characterization results of XRD (X-ray diffractometer) and FE-SEM (field emission scanning electron microscope) revealed that evolutionary selection might predominantly contribute to the formation of the sharply oriented mordenite membrane. The necessary conditions under which evolutiona...

polyimide/nickel oxide (polyimide/nio) nanocomposite was successfully synthesized by sol gel technique, using pyromellitic dianhydriede (pmda), 4,4-oxydianiline (oda) and n,n-dimethylacetamide (dmac) and 10 wt% nickel titanate nanopowders (nps). fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd), scanning electron microscopy (sem), and vibrating sample magnetometer (vsm) we...

cobalt oxide (co3o4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(ii)chloride, triton x-100 and koh in an autoclave at 180 °c for 6 h followed by heating at 400 ºc for 3 h in air. the product have been characterized by fourier transform infrared (ft-ir), uv-vis spectroscopy, powder x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission ...

in this paper, we used tetranuclear copper (ii) schiff base complexes, [cu4 (μ-sal2hn) (μ-n3)2(n3)2] (1) and [cu4 (μ-salophen) (μ1, 1-n3)2(n3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of cuo nanoparticles. the crystallinity, purity and morphology of the cuo nanoparticles were characterized by fourier transform infrared (ft-ir), x-ray diffraction (xrd) and s...

Alloys Fe-(0, 5, 10)Cr-10Al (all in at.%) were oxidized at 900 o C in 1 atm oxygen to study the effect of Cr additions on the oxidation behavior. The oxidation kinetics was recorded with a thermal microbalance. The morphologies and microstructures of the oxide scales were examined using SEM, EDS, and XRD. Fe-10Al developed an Al2O3-rich scale during the initial stage of oxidation, and a non-pro...

This research studies the characterization of activated carbon from tamarind seed with KOH activation. The effects of 0.5 : 1-1.5 : 1 KOH : tamarind seed charcoal ratios and 500-700°C activation temperatures were studied. FTIR, SEM-EDS, XRD, and BET were used to characterize tamarind seed and the activated carbon prepared from them. Proximate analysis, percent yield, iodine number, methylene bl...

in this study, we synthesis one-dimensional (1d) manganese(iii) schiff base coordination polymer [mn(brsalophen)(μ1,3-n3)]n by reaction of mncl2·6h2o and tetradentate schiff base ligand brsalophen at the presence of nan3 in methanol and characterized by elemental analyses (chn) and ft-ir spectroscopy. it was used as a new precursor to prepare spinel type manganese oxide nanowires by a facile so...

this study reports the simple process to synthesis of cuo/cui nanocomposite in a non-aqueous solution. in the conducted experiments cui and dimethyl sulfoxide (dmso) were used as the precursors. moreover, dmso had role of solvent and ligand simultaneously. in experiments the effects of oleic acid as the particles size modifier, temperature and concentration were investigated. crystalline struct...
