Measurements of Pb, Cu, Zn, As, Ni, Hg, and Fe heavy metals and major elements and components such as Ca, HCO3, SO4, Na, K, Mg and Cl in soluble rain fractions were performed on rainwater collected at Arak plain during the rainy seasons of 2012. Concentrations of the heavy metals in the soluble fractions decreased for Fe, Pb, Zn, Ni, Cu, As and Hg, respectively and the major elements and compon...
Dimercaptosuccinic acid (DMSA) coating improves the uptake efficiency presumably by engendering the Fe(2)O(3)-NPs. In the present study, we investigated the possible environmental safety concentrations of Fe(2)O(3)-NPs using different assay systems in nematode Caenorhabditis elegans with lethality, development, reproduction, locomotion behavior, pharyngeal pumping, defecation, intestinal autofl...
Decomposition of transition-metal amidinates [M{MeC(NiPr)2} n ] [M(AMD) n ; M=MnII, FeII, CoII, NiII, n=2; CuI, n=1) induced by microwave heating in the ionic liquids (ILs) 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIm][PF6]), 1-butyl-3-methylimidazolium trifluoromethanesulfonate (triflate) ([BMIm][TfO]), and 1-butyl-3-methyl...
In this work, the effects of preparation methods such as CE oven, microwave irradiation, and ultrasound on the morphology, particle size and crystallinity of MIL-53(Fe) are firstly investigated. Furthermore, the methods are utilized to prepare Pt NPs@MIL-53(Fe). As a result, well-defined Pt NPs@MIL-53(Fe) prepared by microwave irradiation exhibits uniformed morphology, hig...
Nanomaterials have achieved remarkable technological advances in bulk materials due to their excellent physical, chemical and biological properties. cerium oxide (CeO2) nanostructured doped with Fe ions is attractive due to improvement in redox properties, transport property and surface-to-volume ratio. In this research, Fe-doped CeO2 nanoparticles (NPs) were prepared by s...
• Mesoporous nanoparticles enhanced C. sorokiniana activity during biogas upgrading. CO 2 was adsorbed to the mesoporous surface of nanoparticles. CALPECH boosted productivity and carbohydrate content. UV exposure influenced differently depending on iron source. Three different based (NPs) were added Chlorella batch cultures devoted photosynthetic upgrading enhance biofixation: Fe O 3 , carbon ...
In this research, a simple and efficient cathodic electrochemical deposition (CED) route wasdeveloped for the preparation of magnetite nanoparticles (NPs) in an aqueous media. Thesurface of magnetite NPs was also coated for the first time via an in situ procedure during theCED process. In this method, initially, the Fe3O4 NPs (with size ~10 nm) were prepared from theFe2+/Fe3+ chloride bath thro...
The present study aimed to determine the effects of iron nanoparticles (Fe-NPS) on growth performance, survival rate, liver histopathology and some blood and immune parameters of stellate sturgeon (Acipenser stellatus) juvenile. A total of 144 fish (175-195 g) were fed diets containing graded levels of Fe-NPs (0, 25, 50 and 100 mg kg -1 diet) for 8 weeks. Based on results, no significant differ...
application of nanotechnology in medicinal and biological fields has attracted a great interest in the recent yeras. in this paper the cell membrane leakage induced by iron nanoparticles (fe-np) against pc12 cell line which is known as a model of nervous system cell line was investigated by the lactate dehydrogenase (ldh) test. therefore, pc12 cells were incubated with different concentration o...
A facile organic-phase synthesis of monodisperse barium-doped iron oxide (Ba-Fe-O) nanoparticles (NPs) is reported. The Ba-Fe-O NPs can be converted into hexagonal barium ferrite NPs at 700 °C, showing strong ferromagnetic properties with H(c) reaching 5260 Oe and M(s) at 54 emu g(-1). Moreover, the Ba-Fe-O NPs can be assembled into densely packed magnetic arrays, providing a unique model syste...
