Abiotic reduction of 0.1 mM U(VI) by Fe(II) in the presence of synthetic iron oxides (biogenic magnetite, goethite, and hematite) and natural Fe(III) oxide-containing solids was investigated in pH 6.8 artificial groundwater containing 10 mM NaHCO3. In most experiments, more than 95% of added U(VI) was sorbed to solids. U(VI) was rapidly and extensively (> or = 80%) reduced in the presence of sy...
In this work, a new poly (3-hexylthiophene):1.00 mol% Au-loaded zinc oxide nanoparticles (P3HT:Au/ZnO NPs) hybrid sensor is developed and systematically studied for ammonia sensing applications. The 1.00 mol% Au/ZnO NPs were synthesized by a one-step flame spray pyrolysis (FSP) process and mixed with P3HT at different mixing ratios (1:1, 2:1, 3:1, 4:1, and 1:2) before drop casting on an Al2O3 s...
introduction there is an iron mining complex called shahrak 60 km east of takab town, nw iran. the exploration in the shahrak deposit (general name for all iron deposits of the area) started in 1992 by foolad saba noor co. and continued in several periods until 2008. the shahrak deposit comprising 10 ore deposits including korkora-1, korkora-2, shahrak-1, shahrak-2, shahrak-3, cheshmeh, golezar...
The excellent electrochemical performance of greigite (Fe3S4) coupled with its vast abundance and low toxicity make it a good prospect as an anode material for lithium ion batteries (LIBs). In this research, a simple and feasible approach for producing pure phase, small sized, shape-controllable, and stable Fe3S4 nanoplates (NPs) through hot injection of sulfur solution into Fe(iii) solution wa...
Among many kinds of magnetic materials, L10-phase FePt shows almost the highest magnetic anisotropy resulting in high coercivity [1]. Thus, FePt has been intensively studied as material for magnetic recording media with a storage capacity of Tbit/in [2]. After the IBM group reported the synthesis of FePt nanoparticles (NPs) in liquid phase using iron pentacarbonyl [Fe(CO)5] and platinum(II) ace...
We are investigating the redox chemistry of wild-type (WT) and mutant (1-12G) cytochrome P450 BM3. Absorption spectra in solution feature the Fe(III) Soret at 418 nm for WT and a split Soret for 1-12G at 390 and 418 nm. Voltammetry of the proteins within DDAPSS films on the surface of carbon electrodes reveal nearly identical Fe(III/II) potentials (approximately -200 mV vs Ag/AgCl), but signifi...
This study was performed to assess the growth promoting potential of dietary Fe2O3 NPs in Macrobrachium rosenbergii PL. Fe2O3 NPs was supplemented at 0, 10, 20, 30, 40 and 50 mg kg-1 with the basal diet (containing 5.45 mg Iron kg-1). The concentration of Fe in Fe2O3 NPs supplemented diet was increased correspondingly. Fe2O3 NPs supplemented diets were fed to M. rosenbergii PL (initial weight, ...
In the present study, Pb-ZnO, Fe-ZnO, Cd-ZnO and Pb-Fe-Cd-ZnO nanoparticles were synthesized by the sonochemical method and those structural and optical properties were investigated by Fourier Transform Infrared spectroscopy (FTIR), UV-Vis spectroscopy, Field Emission Scanning Electron Microscopy (FE-SEM) and X-Ray Diffraction (XRD). Average crystallite size obtained was 60 nm. Moreover, the di...
