The electrochemical oxidation behavior of m-nitrophenol (m-NP) was studied comparatively on glassy carbon electrode, Pt electrode, PbO2 electrode, SnO2 electrode, and graphite electrode using cyclic voltammetry. The cyclic voltammetry measurements were performed in acidic (1 M H2SO4, pH 0.4), neutral (1 M Na2SO4, pH 6.8), and...

Chlorine oxoanions with the chlorine atom at different oxidation states were introduced in an attempt to systematically tailor the electronic structures of single-walled carbon nanotubes (SWCNTs). The degree of selective oxidation was controlled systematically by the different oxidation state of the chlorine oxoanion. Selective suppression of the metallic SWCNTs with a minimal effect on the sem...

Early stage oxidation behavior of SiSiC cellular lattices with different cell types was studied at 1400 °C in two different environments: a porous burner and an electric furnace with stagnant air. Oxidation and silicon alloy bead formation were observed and identified as the most important factors affecting the integrity of the structures. Lowmelting temperature silicon-based alloys formed from...

in the current work, graphene oxide (go) samples were prepared at room temperature from graphite flakes using a modified hummer's method to produce metal-free electrocatalysts. the effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the go samples was evaluated using x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), ...

OBJECTIVES The aim of the present study was to investigate the effect of thermal oxidation on the corrosion behavior of Ti-5Ag alloy. METHODS The microstructure of Ti-5Ag alloy without and with thermal oxidization treatment were characterized, with commercial pure (CP) Ti as control, by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (...

In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanostructures such as nanobeams, concave/convex nanorings, and nanowires exhibits an extremely different and complex behavior. Such effects have been investigated by the modeling of the mechanical stress generated during t...

electrochemical behavior of i-hydroxypyridine-2-thione and its vanadium complex is studied using polarographic techniques. polarograms of ligand and that of the complex is shown with diffusion characteristics of the waves. cyclic voltagram of thione is investigated which shows that a reversible oxidation reduction of one electron process is taking place. pka of the thione is found to be in clos...
