  • 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…

  • Essay On Peroxidase

    the question is yes. In the experiment, the three standards given were cytochrome c, albumin, and hemoglobin. The expected 3 migration pattern given to me in the lab manual for cytochrome c is that it will migrate to the negative electrode. While in hemoglobin and albumin, it will migrate to the positive electrode. The standard cytochrome c did migrate as expected because according to the lab manual cytochrome c is positively charged causing it to migrate to the negative electrode and it did.…

  • Describe The Industrial Welding Process

    Welding There are 5 main types of welding process commonly used in industrial welding. They are; Gas Metal Arc Welding, oxy acetylene, Gas Tungsten arc welding, flux core, and Shielded metal arc welding. All welding procedures are important and useful for a variety of things. Welding is the process by which two or more pieces of metal are joined or metal has material added to it to fill a hole. Welding process work by heating the base metal, or the material being on, to a liquid state. They…

  • 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…

  • 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…

  • Battery Essay

    We can also use the thermodynamic free energy law to change with the Faraday Law to alter and to calculate used voltage of the cell (which is 4.0 volts) in the chemical reaction: LiC6 + CoO2 = C6 + LiCoO2 In the case of the rechargeable battery, the electrochemical oxidation-reduction reactions are reversible at both electrodes. For example, when the battery is recharged, the overall electrochemical reduction reaction at the negative electrode is identical to the electrochemical oxidation…
