in this research, the activity of mno, produced during steel making in aluminate-rich slags, was investigated.according to thermodynamic equations and mathematical calculation, a series of relations was obtained forevaluation of oxide activity using masson’s theory. the obtained relations were solved according to levenberg- marquardt method and using matlab software. the results were correlated...

here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

nano-graphene oxide was synthesized by the oxidation of graphite powders. the structural nature of the nano-graphene oxide was characterized by a variety of techniques including xrd, tem, ft-ir and uv/vis. the functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. the catalytic activity of nano-graphene oxide was investigated on crossed-...

the use of colored semiconductor oxide like copper (ii) oxide and nickel (ii) oxide for photocatalytic bleaching of rose bengal was investigated in detail. in order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye. progress of the reaction was observed spectroph...

objective(s): the objective of this study was to investigate the antibacterial activities of magnesium oxide nanoparticles (mgo np) alone or in combination with other antimicrobials (nisin and heat) against escherichia coli and staphylococcus aureus in milk.materials and methods: first, the combined effect of nisin and mgo nanoparticles was investigated in milk. then the combined effect of nisi...

nitric oxide (no) is a bioactive molecule, which was found to have several physiological roles, including antioxidant. to have a better understanding of the effects of no concentrations (0, 0.1 and 0.2 mm) on germination, growth, photosynthetic pigments, lipid peroxidation and antioxidant activity of basil (ocimum basilicum l.) under different salinity concentrations (0, 100 and 200 mm of nacl)...

background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

in the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (zno) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...

objective(s) we investigated the effects of low-dose morphine on nitric oxide (no) and angiogenesis in two-kidney one clip hypertensive (2k1c) rats. materials and methods male rats were divided into two groups: sham-clip operated and 2k1c. each group subdivided into saline and morphine (3 mg/kg i.p. 8 weeks) groups. blood pressure, heart rate, plasma renin activity (pra), no concentration and m...
