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…

Welding can be very fun and empowering. Watching the sparks fly from the metals, and seeing the world’s strongest metals be made into what a welder wants for it to become. Welding requires hard work and a considerable amount of practice. It requires hard work, dedication, and concentration. If one welder does not pay attention to their work it could result in a considerable amount of damage to yourself and even others. Welding is the binding together of metals using mechanical machines…

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…

something your institution and instructors have come to terms with in their set rules and instructional guidelines. When citing from a book, the web, or article always cite with the proper citation and any references used. Lastly, always have a reference page at the end of your essay for one to reference back to where you obtained your information for your…

FORMATTING: Basic formatting for an American Psychological Association style paper provides for a title page, an abstract, the main body of text and a references page. VII. SAFEASSIGN/ORIGINALITY REPORTS. Safeassign is a plagiarism detection program offered by Liberty University through the Blackboard learning system that is available to students and instructors as a means to assist in identifying unoriginal…
