A water treatment technology employing the adsorption of dissolved organic contaminants from water and their electrochemical regeneration has been commercialized by Arvia Technology Ltd, UK. This technology focuses the adsorption of pollutants onto the surface of low surface area graphite based adsorbents followed by the anodic oxidation of adsorbed species in an electrochemical cell. However, ...

Herein, we report a green electrochemical oxidative approach to convert large quantities of graphite into graphene oxide (GO). The resulted GO flakes have been characterized using various analytical techniques. It was possible to control the degree of oxidation of the produced GO via controlling the electrochemical parameters of the process.

Electrochemical behaviors of 1-naphthaleneacetic acid (NAA) at an ionic liquid N-butylpyridinium hexafluorophosphate (BPPF6/CPE) modified carbon paste electrode was investigated by cyclic voltammetry (CV) and further used for NAA sample determination. The experimental results showed that NAA at both the bared and the modified electrode showed an irreversible oxidation process, but at the modifi...

The chemical potential of oxygen ions at the novel oxygen pumping anode for electrowinning aluminum was manipulated by the electromotive forces to create thermodynamic stability. It is our anticipation that this newly designed anode can be applied to electrochemical metallurgy of other metals, such as the direct electrochemical reduction of TiO2 in the FFC process.

Surface smoothness is one of the properties determining the performance of stents. Therefore, surface polishing shows its importance in the exploitation and production of stents. The present study explores electrochemical polishing of 316L stainless steel slotted tube coronary stents produced by laser cutting. Acid pickling was also studied as a pre-treatment of electrochemical polishing of the...

A simple electrochemical fabrication of graphene nanomesh (GNM) via colloidal templating is reported for the first time. The process involves the arraying of polystyrene (PS) spheres onto a CVD-deposited graphene, electro-deposition of carbazole units, removal of the PS template and electrochemical oxidative etching. The GNM was characterized by scanning electron microscopy (SEM), atomic force ...

In this paper, the electrochemical behaviour of passive films formed on AISI 321 stainless steel (AISI 321) immersed in 0.1 M NaOH + 0.1 M KOH solution was evaluated by different electrochemical techniques. For this purpose, passive films were formed at open circuit potential for 1 to 12 hours and then electrochemical measurements were done. The polarization curves suggested that AISI 321 showe...

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...
