transfer ability of the nanohybrids. The resistance value of P(AA-co-EHA)/ silica-modified electrodes containing APTS (121.9 Ωcm2) and lower silica content decreased obviously in comparison with resistance value (2671 Ωcm2) of the modified electrodes comprising MPS with higher amount of SiO2. These results were in agreement with the results from CVs. Meanwhile, since the Bode and Phase diagrams of the modified electrode had two peaks and inflection points, respectively two capacitive responses…

Abstract: We describe the successful synthesis of Polypyrrole-Gold nanocomposites (PPy-Au NCs) by the chemical oxidative polymerization of pyrrole with ferric chloride as an oxidizing agent, in the presence of a colloidal suspension of gold nanoparticles. Gold nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier…

Electrochemical Performance. To evaluate the electrochemical behaviors of the highly open framework of the as synthesized LTH on nickel foam electrodes NCA-L-@NF, NCA-L@G-NF and NCA-L@ BG-NF with three different feeding mole ratios , which is the best morphological foundation for fast redox reaction and charge accumulation, its potential application in high-performance supercapacitor has been investigated by cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance…

The carbon supported PtFeS catalysts were prepared by a modified polyol method. In brief, 0.3 g carbon (Ketjen-black heat-treated at 2250 °C, SE = 160 m2 g-1) was dispersed in 135 g ethylene glycol. 5.993 g of 8 wt% H2PtCl6 (Umicore; Pt content, 39.8 wt%), 1.874 g of 8 wt% FeCl3. 6H2O (Sigma-Aldrich), and 0.352 g of 8 wt% (NH2)2SC (Sigma-Aldrich) previously mixed in ethylene glycol were added to the dispersion. The pH of the stirred reaction mixture was adjusted to ∼11 using 1 M NaOH dissolved…

features. It allows protons but it is impermeable to gases, and hence it 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…

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 reaction that proceeded at the negative electrode when the battery was discharged, only written in reverse. For the non-rechargeable battery, they cannot have their process reversed.…

The organization selected for the present paper is Energizer Holding, Incorporated. Energizer recently splint from a parent company and in this paper, I will prepare a strategic plan to grow the business over the next three years. Including in the development of the paper will be a description of the company’s history, products and major competitors. In addition describe what is the current direction of the organization, conduct a quick SWOT analysis to determine areas that offer opportunities…

and the reduction reaction rate of the deposition. According to Nernst equation [10], the conversion relationship between the equilibrium electrode potential and the standard electrode potential is as…

Although Animal Farm is quite a short book, there is time for George Orwell to develop characters in a manner that makes them appealing (or appalling) to the readers. His greatest success in this area is Boxer, with his mottoes, "Napoleon is always right" and "I will work harder". On the symbolic level, Boxer represents the Russian workers who trusted Stalin and made enormous sacrifices to ensure the success of the October Revolution. In the book he is one of the most sympathetically drawn…

This arrogance towards the lower class cost someone’s life, just because of this consideration that they are better than the other. And as the inspector later says in Act Three, on how others futures are ‘All intertwined with our lives, and what we think and say and do.’ when referring to how people like Eva Smith, i.e. lower class, can be immensely affected by them, of a higher class. Gerald and Eric know Eva Smith on a more personal level than the rest of…
