Green biosynthesis of silver - functionalized multiwalled carbon nanotube (Ag/FMWCNT) nanohybride from silver nitrate solution using water extract of Satureja hortensis L as reducing agent and FMWCNT as anchoring agent at room condition was succesfully carried out. Water-soluble organics present in the plant materials were mainly responsible for the reduction of silver ions to nano-sized Ag par...

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...

< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

The SiO2-CaCl2 hybrid porous materials were prepared by the sol-gel method. This process was conducted by the hydrolysis and condensation of Tetraethyl orthosilicate (TEOS) by replacement of ethanol from alcogel and drying at the ambient temperature to obtain xerogel structure. The alcogel samples were synthesized from TEOS, EtOH, H2O, HCl, NH4OH and CaCl2, while the total molar ratio of the co...

Dispersion of 2D carbon nitride (C3N4) nanosheets into a nickel phosphorous (NiP) matrix was successfully achieved by ultrasonication during the electroless plating of NiP from an acidic bath. The morphology and thickness, elemental analysis, phases, roughness, and wettability for as-plated and heat-treated nanocomposite were determined by scanning electron microscopy, energy-dispersive X-ray s...

In this experimental work, PbS/ZnS/ZnO nanocomposite was synthesized via a simple co-precipitation method. The effect of Zn2+/Pb2+ mole ratio was investigated on the product size and morphology. The products were characterized via scanning electron microscopy to obtain product size and morphology. The optical properties of the nanocomposites were studied by ultra violet-visible spectroscopy. Ph...

Exfoliated poly (Chloromethyl styrene-co-styrene)-g-polyacrylonitryle/organo- modified montmorillonite [P(CMSt-co-St)-g-PAN/O-MMT] nanocomposite was synthesized through solution intercalation method by using atom transfer and nitroxide mediated radical polymerization. At first, poly (chloromethyl styrene-costyrene) copolymer was synthesized by nitroxide - mediated “living” free radical polyme...

Titanium dioxide has been widely used for photo-catalytic and self-cleaning activities. In this study, TiO2 /SiO2 /Co nanocomposite was prepared by sol-gel method in the presence of Polyvinyl Pyrrolidone (PVP), and Hydroxyl Propyl Cellulose (HPC) as additives, and characterized by IR spectra, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (X...

nanocomposites of multi-walled carbon nanotubes and titanium dioxide (mwcnt/tio2) were synthesized by the sol-gel method. regarding hydrophobicity of carbon nanotubes (cnts), benzyl alcohol was used as the linking agent between cnt powder and tio2 gel which was prepared from the precursor of titanium tetraisopropoxide. the prepared samples were treated under thermal treatments. a part of the sa...
