vehicles, owing to their high power density, high energy density, and long cycle life.1–3 However, there are still many critical challenge to increasing the energy, power density, and improved cycling stability.4–6 In particular, selecting noble electrode materials is the hottest topics in the LIB field. Among them, bulk metal oxide such as Fe2O3, SnO2, ZnO, and In2O3 are promising material owing to their high theoretical capacity (~1000 mAh g-1), which considerable exceeds those of commercial…

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…

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…

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…

Q1. Describe the construction and operation of a Ni-Cad battery. Compare and contrast the Ni-Cad battery with a Lead-Acid battery. a. Construction: figure 1. Ni-cad battery construction Ni-Cad battery refers to Nickel-cadmium battery which is widely used in industrial world. Basically, the Ni-Cad battery consists of positive and negative plates, separators, electrolyte, cell vent, and cell container. The positive plate in Ni-Cad battery is Nickel Hydroxide Ni(OH)2. However, the negative…

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…

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…

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…

UNIT ELECTRODES In transcutaneous electrical nerve stimulation (TENS) treatment for pain relief, electric signals are transmitted from the device (known as TENS unit) through electrodes placed on the skin surface to the nerves under the skin. If you don’t use these electrodes properly, your body can experience discomfort or pain even though the signals are generally mild and safe. Here are 5 things you should know about electrodes in the TENS unit: 1. Where to put or not put the electrodes?…

by using electrodes are placed on the scalp, and then signals go to a computer to record the results. Abnormal patterns in EEG indicate seizures and other problems [3][6]. The importance reason for using EEG is to diagnose and show seizure disorders. Also EEGs help to help to identify causes of other problems like sleep disorders and changes in behavior. To evaluate the brain activity after head injury or before heart or liver transplantation the EEG is a good choice [3]. The electrodes in…
