  • Analysis Of TRGO

    continuously pursue new electrode materials for constructing an enhanced electrochemical platform for sensing. In this study, hydrothermally-assisted reduced graphene oxide (TRGO) was synthesized using an environment friendly reducing agent in optimum time to easily exfoliate coating solution and substitute on the microelectrode. Series connected distributed sensing electrodes were fabricated and patterned with TRGO added platinum nanoparticles (PtNP), chitosan-enzyme composites, and nafion,…

  • Capacitance Properties Of Polyaniline Essay

    concentration solutions of H2SO4 on a stainless steel substrate. The capacitance properties of polyaniline (PANI) films, have been determined and examined in the selected media of two different concentrations of H2SO4 acid using cyclic volammetry technique. Cyclic voltammetric measurements have shown that PANI films grown by cycling the potential between -0.2V and 1 V in 1M H2SO4 and 2M H2SO4 on SS electrode. The electrochemical characterization of the electrode was carried out by means of…

  • Principle Of Electrochemical Impedance Spectroscopy

    method is plotted and graphical data is obtained using a Bode plot or a Nyquist plot. In electrochemical impedance spectroscopy four elements are used to explain the impedance behavior: ohmic resistance, constant phase element, Warburg impedance and capacitance. To characterize a biological materials like antigen or antibodies, electrodes should be introduces into the system, thus it forms an electrochemical…

  • Formation Of Carboxylic Acid Group

    obtained EIS spectra can be made by numerical fitting and the use of equivalent circuits depicted in Figure 7(b) and Zsimp Win software (version 3.21). As shown in Figure7(a). the Nyquist plot for the bare GCE exhibited a very small semicircle, which suggested a low [Fe(CN)6]-3/-4 transfer resistance. Whereas P(AA-co-EHA)/ silica nanohybrids were modified onto the bare GCE surface, the [Fe(CN)6]-3/-4 transfer resistance values (Rc, Table2) increased dramatically, which showed poor electron…

  • Ptfe Lab Report

    performed using an AXIS (Q2000) photoelectron spectrometer equipped with mono-Al-Ka X-ray source operating at 1486.6 eV. Electrochemical performances were obtained by the thin active layer rotating disk electrode method using Nafion® as a binder using a three-electrode electrochemical cell. Cyclic voltammogram (CV) for the ECSA was recorded in the potential range 0.05–1.2 V (vs. normal hydrogen electrode (NHE), a scan rate of 20 mV s-1) at RT in 0.1 M HClO4 solution, saturated with nitrogen by…

  • Operating Principles In PEM Fuel Cell

    is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer membrane. A schematic diagram of cell configuration and basic operating principles is shown in Fig. 1.1. Hydrogen, which is fed into one side of the membrane, splits into its primary elements, i.e., one proton…
