Fabrication of metallic nanopillar array structures and their application as electrodes in electrochemical-based biosensors are discussed in this report. Vertically standing nanopillar array structures were fabricated using an electrodeposition technique and their electrochemical characteristics were evaluated. For possible use in biosensing applications, these standing nanopillars should have ...

An ultrafine grain surface layer with average crystallite size of 28 nm was produced on annealed mild steel through a wire brushing process. The effects of grain size reduction on the inhibition performance of sodium phosphate were investigated using polarization and electrochemical impedance spectroscopy (EIS) measurements. The crystal grain size of wire brushed surface was analyzed by X-ray d...

In this study, decolorization of wastewater samples taken from the paper industry is investigated using electrochemical peroxidation process. The process a part advanced oxidation processes, which based on Fenton’s chemical reaction, provided by addition external H2O2 into reaction cell. iron used as anode and graphite cathode put at fixed distance 30 mm in glass cell was filled with solution c...

Electrode materials play a decisive role in almost all electrochemical energy storage devices, determining their overall performance. Proper selection, design and fabrication of electrode materials have thus been regarded as one of the most critical steps in achieving high electrochemical energy storage performance. As an advanced nanotechnology for thin films and surfaces with conformal interf...

In this investigation, attempts were directed to study the inhibitive effects of nitrite and phosphate base inhibitors for the carbon steel alloy samples, which are used in an acid gas treatment process (The SULFIRAN® solution), in Fe-EDTA solution. Electrochemical techniques, i.e. polarization curves and electrochemical impedance spectroscopy (EIS), were used to evaluate the inhibition efficie...

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 ...
