A series of indole (In) and carbazole (Cz) derivative monomers have been synthesized, such as 4-[3-carbazolyl] (4In-3Cz), 5-[3-carbazolyl] (5In-3Cz), 6-[3-carbazolyl] (6In-3Cz), 7-[3-carbazolyl] (7In-3Cz). The comonomers synthesized by Stille coupling reaction were characterized 1H-NMR elemental analysis. Potentiodynamic method was used for electropolymerization comonomers, Indole, Cz, the mixt...

The light-weight aluminium alloys play an important role in reducing emissions from the transport industry. However, to take full advantage of these, corrosion mechanisms that govern their failure need be properly understood. Hence, electrochemical response, especially after passive film breakdown, alloy AA5083 was analysed via potentiodynamic polarisation. By starting scans at relatively negat...

AISI 316 stainless steels were coated with 250 nm Ni film by electron beam deposition and post-annealed at different temperatures with a nitrogen flow of 600 cm3min-1 nitrogen. The prepared samples were corrosion tested in 1.0 M sulphuric acid solution using potentiodynamic technique. Crystallographic and morphological structure of the samples were analyzedanalysed by X-ray diffraction (XRD) an...

Ion implantation is a surface modification technology to produce new material on the surface by impingement of high energy ions from the ion accelerator. In this work, AISI 304 stainless steels were coated with 90 nm Ni film by electron beam deposition and implanted by a flow of 5×1017 N cm−2 at 400 K temperature with different implantation energies of 10, 20, 30 and 40 keV. The prepared sample...
