Synthesis of Iron Oxide Nanoparticles using Borohydride Reduction
Iron oxide (Fe2O3) nanoparticles were synthesized by a simple approach using sodium borohydride (NaBH4) and Iron chloride hexahydrate (FeCl3.6H2O). Their physicochemical properties were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and electron dispersive spectroscopy (EDS). XRD pattern showed that the iron...

متن کاملThe reduction of cozymase by sodium borohydride.
Cozymase (diphosphopyridine nucleotide, DPN) has been assayed by a variety of biochemical and chemical methods (1). Among the simplest procedures has been the determination of the light absorption of reduced DPN at 340 rnp after reduction by sodium hydrosulfite. Since special precautions are required to remove completely the excess reducing agent which absorbs in this region, it appeared advant...
متن کاملA Simple Method for Synthesis of Strontium Ferrite Nanoparticles and their Polymeric Nanocomposites
Hard magnetic SrFe12O19 (SrM) nanoparticles were synthesized by a facile sonochemical reaction. The magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. The strontium ferrite nanop...
متن کاملReduction of Chlorophyllides, Chlorophylls and Chlorophyll Derivatives by Sodium Borohydride.
Sodium borohydride is a well known reducing agent. In methanol at room temperature formyl and keto groups are readily reduced to alcohol groups, while ester and carboxyl groups, carbon-carbon and carbon-nitrogen double bonds are only reduced with difficulty (2, 17). Of the groups present in chlorophyll b the C3 formyl and the C9 keto groups should be amenable to reduction, while the C2 vinyl an...
