The corrosion inhibition properties of the benzothiazole BTH and benzotriazole BT inhibitors on the aluminum in 0.25 M HCl solution were studied. Electrochemical impedance spectroscopy EIS, electrochemical noise EN and potentiodynamic polarization techniques were used to investigate the inhibition properties of the inhibitors. Scanning electron microscope SEM was also utilized in order to inves...

In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...

in this study, the effects of forming method (extrusion) and environmental factors (solution ph and temperature) on the corrosion performance of az91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (eis), scanning electron microscopy (sem) and salt spray techniques. the polarization test results of the specimens showed that simple sh...

In this paper, we investigated the electrode structure of the electrical bio-sensor to reduce impedance measurement fluctuation. Five pairs of the same electrodes were formed on the PCB substrate, and a fluidic channel was constructed with a double-sided tape and polycarbonate cover so that all the electrodes had the same reagent distribution. In order to find an electrode structure with little...

a chemically modified carbon paste electrode with multiwall carbon nanotube (mwcnt) was prepared and used as a sensor for cu2+ ion. the unique chemical and physical properties of cnt have paved the way  to  new  and  improved  sensing  devices.  a  central  composite chemometrics  design  was  applied  for  multivariate  optimization  of the  effects  of  three  significant  parameters  (graphi...

Different types of charge storage mechanisms at unmodified graphite vs. glassy carbon electrodes in acid sulphate supporting solution containing potassium hexacyanoferrate (II) redox active electrolyte, have been revealed by electrochemical impedance spectroscopy and supported by cyclic voltammetry experiments. Reversible charge transfer of Fe(CN)6 redox reaction detected by assessment of CVs o...
