The objective of this study was to explore the extent of mineralization of Biodigester Effluent (BDE) by Electrochemical Treatment using aluminum electrodes in monopolar configuration. The benefit of determining a COD/TOC ratio is becoming evident. While both parameters are useful independently, the ratio of the two values, and the fluctuation of this ratio, is an excellent indicator of the org...

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...

This paper reports a rapid microchip-based electrochemical enzyme immunoassay with surface-functionalized poly(dimethylsiloxane) (PDMS) channel. The microchip fabricated on a glass substrate by photolithography consists of a three-electrode system for electrochemical detection and is assembled with the antibody-immobilized PDMS channel by plasma treatment. For effective immobilization of target...

Here, we report the draft genome sequence of Desulfuromonas acetexigens strain 2873, which was originally isolated from digester sludge from a sewage treatment plant in Germany. This bacterium is capable of anode respiration with high electrochemical activity in microbial electrochemical systems. The draft genome contains 3,376 predicted protein-coding genes and putative multiheme c-type cytoch...

The effect of various electrochemical pre-treatment methods on the surface and electrochemical properties of screen-printed carbon paste electrodes (SPCE) prepared with three different commercial products was examined. It was observed that a positively charged redox couple, e.g., hexaammineruthenium(III), exhibited quasi-reversible behavior at the untreated SPCE. However, the cyclic voltammogra...

Pesticides are used worldwide in large quantities to increase yield agriculture. On the other hand, they general toxic/persistent organic pollutants presenting strong adverse effects environment and human health, including acute chronic toxicity. Consequently, water polluted by pesticides should be treated efficiently before its release into receiving bodies protect natural aquatic environment....

in the present work the effects of plasma nitridization on the passivation behavior of aisi 316l was investigated. to do this; nitriding treatments were carried out at 420°c for 1, 2, 4 and 16 hours. the phase composition and structure of the nitrided layer were studied by low angle x-ray diffraction and scanning electron microscopy. the hardness of samples also was evaluated by vickers microha...

Electrochemical oxidation is a promising technology to treatment of bio-refractory wastewater. Coking wastewater contains high concentration of refractory and toxic compounds and the water quality usually cannot meet the discharge standards after conventional biological treatment processes. This paper initially investigated the electrochemical oxidation using boron-doped diamond (BDD) anode for...
