Sugar industry is an oldest accommodates industry in the world. It required and discharges a large amount of water for processing. Removal of chemical oxygen demand and color through the electrochemical process including hybrid iron and aluminum electrode was examined for the treatment of cane-based sugar industry wastewater. Most favorable condition at pH 6.5, inter-electrode gap 20 mm, curren...

Boosted by the rapid advances of science and technology in the field of energy materials, Li-ion batteries have achieved significant progress in energy storage performance since their commercial debut in 1991. The development of nanostructured electrode material is regarded as one of the key potentials for the further advancement in Li-ion batteries. This feature article summarizes our recent e...

We report a direct square-wave voltammetric study of the iron-sulfur enzyme, aconitase, at the pyrolytic graphite edge electrode. New and established redox driven reactions were observed and the equilibrium reduction potential for each couple was determined: E0'[3Fe-4S]1+/0 = -268 mV, E0'[4Fe-4S]2+/1+ = -450 mV, E0'[4Fe-4S]3+/2+ = +100 mV, E0'Linear Form = -281 mV, and putatively, E0'[3Fe-4S]0/...

A comparison of experimental results with numerical simulations is presented that shows the influence of electrode geometry on the impedance response for reactions involving one adsorbed intermediate. The local electrochemical impedance measurements performed on an iron disk electrode were in qualitative agreement with the numerical calculations. Both the experimental and calculated local imped...
