in this work, copper oxide nanoparticles have been synthesized via extractive rosmarinus officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (ch3coo)2cu+h2o individually as cu sources. it was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0c. powder x-ray diffrac...
The production and use of iron oxide nanoparticles are growing exponentially due to its wide applications in different fields of science and technology. The objective of this study is to synthesize iron oxide nanoparticles, and modification of its surface to make it less toxic. The iron oxide nanoparticles were synthesized by chemical co-precipitation method, and surface modification was done u...
background and aims: although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (ag nps) and magnesium oxide nanoparticles (mgo nps) on the cardiomyocytes. materials and methods: cardiomyocy...
introduction: our previous study has showed that chronic administration of magnesium oxide nanoparticles (mgo np) can reduce anxiety in adult male rat. in this study the effects of mgo np on anxiety induced by morphine withdrawal were investigated in adult male mice. methods: adult male nmri mice (weighing 27 ± 3 g) divided into groups: control, receiving intraperitoneal (i.p.) injection of mgo...
background & objectives: direct addition of antimicrobial materials to food during food processing is an effective method for controlling microbial contaminants of food and extending the shelf-life of food products. objective of this research was to study the antimicrobial effect of zinc oxide (zno) nanoparticle and potential applications of zno nanoparticles in terms of controling two food...
in comparison to the previous researches, zro2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. the as-prepared zro2 nanoparticles by co-precipitation method were characterized with x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the surface area of the sample was characterized by bet method. the eff...
the aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. the paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.aluminum oxide (al2o3) nanoparticles were synthesiz...
in this paper, cuo nanoparticles have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem).
this paper focused on a simple approach for synthesis of molybdenum oxide (moo3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. for more investigations, besides microwave heating, the obtained solutions were also treated by conventio...
The impacts of zinc oxide nanoparticles on embryonic development following oocyte stage exposure are unknown and the underlying mechanisms are sparsely understood. In the current investigation, intact nanoparticles were detected in ovarian tissue in vivo and cultured cells in vitro under zinc oxide nanoparticles treatment. Zinc oxide nanoparticles exposure during the oocyte stage inhibited embr...
