Oxidation behavior of AZ91D magnesium alloy with 3YSZ coating and aluminum interlayer was studied in air at 250 °C using electrochemical impedance spectroscopy EIS, scanning electron microscopy SEM, and X-ray diffraction XRD. The oxidation process was carried out in various duration times from 1 to 10 h. A three-electrode electrochemical cell was employed for all the EIS measurements. Also, to ...

Alkaline chlorination, an efficient but high chemical cost process, is commonly employed for cyanide (CN−) removal from CN-rich wastewater streams. CN− and recovery through the precipitation of Prussian Blue (Fe4III[FeII(CN)6]3, PB) or Turnbull’s (Fe3II[FeIII(CN)6]2, TB) were realized using iron salts, leading to a cost-effective sustainable process producing valuable product. However, PB TB hi...

A novel parylene-embedded carbon nanotube nanoelectrode array is presented for use as an electrochemical detector working electrode material. The fabrication process is compatible with standard microfluidic and other MEMS processing without requiring chemical mechanical polishing. Electrochemical studies of the nanoelectrodes showed that they perform comparably to platinum. Electrochemical pret...

The underpotential deposition(UPD) phenomena is very interesting not only because of its fundamental importance but also due to its noticeable growing impact on the material science. The amazing possibility of control the deposition process down to monolayer results in new kind of materials with different properties than bulk ones embracing they catalytic, electronic or magnetic properties. Exc...

the applications of electrochemical machining are increasing because of increasing requests of industries for materials with high strengh and high hardness. regular ecm uses a tool with spicified profile shape that is similar to final shape of workpiece. in this reasearch a nozzle that delivers electrolyte to the machining gap is used for machining cylinderical workpieces. by moving the electro...

−The paper presents a process for the electrochemical recovery of silver(Ag) by electro deposition on the electrode surface from the waste solutions of Ag(I)/Ag(II) redox system in nitric acid medium used for the mediated electrochemical process. Electrochemical recovery was carried out in an undivided cell with DSA-O2 electrodes at room temperature condition. At an optimized current density of...
