In this work, high-performance electrochemical energy storage electrodes were developed based on nickel oxide (NiO)-coated nickel (Ni) foams prepared by a sparking method. NiO nanoparticles deposited on Ni foams with varying sparking times from 45 to 180min were structurally characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray...
Size-controlled growth of single-crystalline TiO 2 nanowires by oxidation of titanium substrates was investigated. The growth was performed on titanium substrates in the presence of ethanol vapor at a low pressure and high temperatures. The results of characterization indicate that the mean diameter of the nanowires depends on the growth temperature whereas the mean length increases linearly...
