in present study we studied using green routes for microwave assisted synthesis of alumina nanoparticles from aluminum nitrate. it was revealed that when plant extracts are used, no specific stabilizer is needed. structural characterization of nanoparticles was studied using x-ray diffraction that showed semi-crystalline structure for two of plant extracts, other xrd patterns had no significant...

al(oh)3 nanoparticles were synthesized by a simple precipitation reaction. the effect of various amines like ethylene diamine, propylene diamine, triethylenetetramine and tetraethylenepentamine as precipitating agents on the morphology of al(oh)3 nanostructures was investigated. the influence of al(oh)3 nanoparticles on the flame retardancy of the poly vinyl alcohol (pva) matrix was studied usi...

in this work, a new aluminum matrix nanocomposite reinforced with beta-magnesium aluminide nanoparticles was produced by powder metallurgy technique. the prealloyed al-40 wt.% mg intermetallic ingot was milled for 100 hours to synthesize β-al3mg2 nanoparticles with the average size of 25 nm. different amounts of nanoparticles were added to al matrix powder and the mixture was then milled for 10...

We investigated whether Aluminum (Al) doping tunes band gap energy level as well as selective cytotoxicity of ZnO nanoparticles in human breast cancer cells (MCF-7). Pure and Al-doped ZnO nanoparticles were prepared by a simple sol-gel method. Characterization study confirmed the formation of single phase of Al(x)Zn(1-x)O nanocrystals with the size range of 33-55 nm. Al-doping increased the ban...

in this study, multi wall carbon nanotubes (mwcnts) were synthesized by chemical vapor deposition (cvd) method using two different catalysts (fe nanoparticles) and (ni nanoparticles) with  two different substrates: quartz and alumina. acetylene gas was used as a carbon source and argon as a carrier gas at different temperatures and different times to study the effects of these parameters on cnt...

SnO2 nanoparticles with different percentage of Al (5%, 15%, and25%) were synthesized by sol-gel method. The structure and nature of nanoparticles are determined by of X-ray diffraction analysis. Also, morphology of the samples is evaluated by SEM. Moreover, the optical properties of the samples are investigated with UV-Visible and FT-IR. The XRD patterns are in...

The present study aims at developing A356/Al2O3(np) nano-composite with a novel and cost effective method for attaining homogeneous dispersion of Al2O3 nanoparticles in the Al matrix. In the current research, Al micro powders distributed on aluminum foil and then Al2O3 nanoparticles ultra-sounded in ethanol and sprayed on Al substrate. Subsequently, the sandwich foil was added to molten A356 du...
