ZnO- nanoparticles with an average particle size of 24 nm were successfully synthesized using the microwave assisted sol- gel technique. Structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy disperse spectrum (EDS) and Fourier transform infrared spectroscopy (FTIR). The band gap ene...

In this work, Ag-Cu nanoparticles (with different percentages of copper, 10%, 25%, 50%, 75% Cu) were synthesized by wet chemical method. Copper(II) sulfate and silver nitrate were taken as metal precursors, ascorbic acid as reducing agent and anhydride maleic (MA) as a modifier. The prepared nanoparticles were characterized by means of X-ray diffraction (XRD) technique and scanning electron mic...

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

in this paper, carbon nanotubes (cnts) were added into chitosan (cs) hydrogels in the form of chitosan modified cnts (cs-cnts) composites to prepare carbon nanotubes hydrogels (cnts-gel). the products, named cs-mwcnts, were characterized by scanning electron microscope (sem) and fourier transform infrared (ftir) spectroscopy. swelling properties and effect of ph on controlled release performanc...

ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...

in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...

Cisplatin is a common chemotherapeutic agent that used for treatment of many solid cancers. Rapid identification of chemotherapy resistance is very important and may lead to effective treatment plan. Spectroscopy techniques, such as infrared spectroscopy, which are sensitive to biochemical composition of samples, have shown potentials to discriminate tissues. Developing in Fourier transform inf...

metal nanoshells consists of a dielectric core surrounded by a thin noble metal shell, possess unique optical properties that render nanoshells attractive for use in different technologies. this paper reports a facile method for growth of small gold nanoparticles on the functionalized surface of larger silica nanoparticles. mono-dispersed silica particles and gold nanoparticles were prepared by...
