  • Lithium Ion Battery Case Study

    The Anode What is Anode? What is anode fabricated from in Li-ion battery? What material could be replacement of ion material however failed? What is design and structure of anode in Lithium ion(Lithium ) battery? What is the reaction/process that are undergoing in anode? What are the recent advancements in anode of Lithium ion(Lithium ) battery? What are the challenges that are still left in the field? 1) The anode is the negative electrode of a galvanic cell and is related to the oxidation or the discharge of electrons into the external circuit in the main into the solution. • The anode attracts electrons or anions from the cathode or the electrolyte. • The associate anode may be a supply of charge or work as an negatron acceptor. 2) The…

  • Julius Caesar, What Is A Roman Tribune?

    What is a Roman tribune? A Roman tribune is soldier who is selected by the citizens ,the Roman people in this case, to help protect the people from oppressive government leaders ,who would try to take the people 's rights ,and make sure the citizens upheld the laws the government made. Having a tribune kept an equal balance of equality to keep the people from attempting treason against their leaders and keeping the leaders from becoming dictators over the people and abusing their power. In order…

  • 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…

  • Microscopyrrole Synthesis Essay

    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…

  • 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…

  • Floating Slimes Essay

    Silver, lead, arsenic, bismuth, antimony, selenium, and nickel are common impurities existing in copper anodes. Some impurities dissolved from the anodes can precipitate, if their concentrations in the electrolytic solution are above saturation levels. Some of these precipitates can settle down but some are floating slimes and can be a source of cathode contamination by their incorporation into the cathode 16. These floating slimes are amorphous and typically have compositions of Sb-As-O and…

  • 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…
