To improve network-functioning, an arc discharge method was developed for the synthesis of nano iron oxide with “neural-network” morphology. Iron wires with diameters of 0.01-0.05 cm were subjected to currents of 50-200 A, until explosions occured in the open air. The XRD and RAMAN spectra of the as-prepared-products indicate formation of nano-Fe2O3 (tetragonal and monoclinic) crystals. Their SEM images show fabrication of nano iron oxide with three different morphologies: spheres, chains, and a “neural-network” biological form. While the latter is unprecedented, our fabrications of nano iron oxide with both sphere and chain morphologies are reproductions of previously reported results. The sphere shaped nanoparticles show a uniform distribution with sizes in the range of 50-250 nm. The specifications of the chain nano products appear consistent with those reported.
