In vitro genotoxic effects of ZnO nanomaterials in human peripheral lymphocytes
(Springer, 2014)
In this study, possible genotoxic effects of zinc oxide (ZnO) nanoparticles were investigated in cultured human peripheral lymphocytes by using chromosome aberrations and micronucleus assays (MN). For this purpose, the ...
Immobilization of a- amylase on reactive modified fiber and its application for continuous starch hydrolysis in a packed bed bioreactor
(Wiley-V C H Verlag Gmbh, 2014)
In this study, the enzyme -amylase was immobilized on reactive modified poly (ethylene terephthalate) fiber. The activities of free -amylase and immobilized -amylase were compared in a batch starch hydrolysis system. Optimum ...
Removal of Common Heavy Metals from Aqueous Solutions by Waste Salvadora persica L. Branches (Miswak)
(Springer International Publishing Ag, 2014)
The adsorption ability of miswak (Salvadora persica L.) waste was investigated for the removal of common heavy metals; Pb(II), Cu(II), Ni(E) and Cd(II), from aqueous systems. The miswak mainly consists of saponins, tannins, ...
Increasing the crystallite and conductivity of polypyrrole with dopant used
(Springer Heidelberg, 2014)
The chemical polymerization method is very convenient for obtaining a plurality of the polymer. Chemical synthesizes of polypyrrole (PPy) were performed in acetonitrile solutions containing different dopants: dodecylbenzene ...
Modification of glassy carbon electrode in basic medium by electrochemical treatment for simultaneous determination of dopamine, ascorbic acid and uric acid
(Elsevier Science Sa, 2013)
In this paper, a modified glassy carbon electrode was prepared by electrochemical method in basic media (0.5 M NaOH solutions) and was used to electrochemically detect dopamine (DA), ascorbic acid (AA), uric acid (UA) and ...
Synthesis and Characterization of Chitosan/Polyvinylpyrrolidone/Zeolite Composite by Solution Blending Method
(Springer, 2014)
Polymer/clay composites have been studied for several decades; in the study, polymer/zeolite composite beads have been prepared by a simple solution blending method using chitosan, polyvinylpyrrolidone and zeolite particles ...
Ferrocene Derivatives Carrying Urea, Thiourea, and Sulfonamide Moieties: Synthesis and Evaluation of Antibacterial and Antifungal Activities
(Hindawi Publishing Corporation, 2013)
In the present study, some novel ferrocene derivatives carrying urea, thiourea, and sulfonamide groups were synthesized, and all compounds were characterized by spectral and elemental analyses. These compounds were screened ...
Pyrolysis of Table Sugar
(Hindawi Publishing Corporation, 2013)
Table sugars were pyrolyzed at different temperatures (300, 400, and 500 degrees C) in a fixed-bed reactor. The effect of pyrolysis temperature on yields of liquid, solid, and gaseous products was investigated. As expected ...
Influence of ruthenium alkylidene complexes bearing tricyclohexylphosphine or 3-bromopyridine ligand on the properties of fluorine containing polymers
(Springer, 2013)
The catalytic performance of ruthenium alkylidene complexes bearing tricyclohexylphosphine or 3-bromopyridine ligand in the ring opening metathesis polymerization (ROMP) of fluorine containing monomers, exo-N-4-fluorophe ...
Ring opening polymerization of 2-aminothiazole with iron(III) chloride
(Springer, 2013)
Poly(2-aminothiazole), PAT, was synthesized by the chemical polymerization of 2-aminothiazole, AT, with FeCl3 center dot 6H(2)O in 1,4-dioxane. The effect of temperature, monomer, and initiator concentration and polymerization ...
