The Physics behind the Electric Vehicle It has been estimated that there will be approximately 1200 million motor vehicles by the year 2020. That is almost twice the number of cars that are already traveling on our busy roads. Due to this ever increasing vehicle population, the demand for fuel will continue to increase as well. With the depleting supply of oil already an issue for the U.S. especially, there is a growing interest in alternative energy fuels that can be used to power motor vehicles

The following chapter discusses background information on quadcopters, structural batteries, graphical user interfaces, and my research objectives. 1.1 Problem Statement The advances in electronics and lightweight materials over the last few decades have resulted in the popularization of quadcopters. Whether for recreational, military, or commercial use, people are beginning to recognize the potential of quadcopters. One company in particular that is looking to exploit the use of drones on a massive

the changes in resistance value between an active electrode where the cells are attached and a counter electrode using the growth media as an electrolyte (figure 1). Once the cells are seeded on the ECIS gold electrodes the current is forced to flow either below, between or through the cells, thus providing measurement of three different parameters; barrier function (Rb), cell membrane capacitance (Cm) and the height between cells and electrodes (h). These parameters are are further analyzed and

Each one of the six cells contains a cathode of lead (IV) oxide and an anode of lead. A sulfuric acid solution that is highly acidic (pH as low as 0) provides the solution for each electrode to be immersed in. (Lead-acid batteries, no date) An example of a lead acid battery: (Gravitatechnomech, 2015) The electrode reactions are: Anode: Pb(s) + H2SO4(aq) → PbSO4(aq) + 2H+ (aq) + 2e- Lead + Sulfuric Acid → Lead Sulfate + Hydrogen + 2 electrons Cathode: PbO2(s) + H2SO4(aq) + 2H+ (aq) + 2e- → PbSO4(aq)

behave: a primary and a secondary battery. Primary batteries are disposable after one use and secondary batteries can be reused after being charges. In primary batteries once the electrodes have changed during battery use, they cannot b0e changed back. Secondary batteries can be recharged, and the initial make-up of the electrodes can be changed by a reverse-current. Primary batteries are mainly used in devices that require low amounts of energy and are not left on perpetually. Secondary batteries are

standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the theoretical and the experimental standard electrode potentials. The sources of error are incorrect solution preparation and contaminated materials. The second part of the experiment uses standard electrode potentials

The negative electrode is zinc, and the positive electrode is manganese dioxide. In the battery, potassium hydroxide is the electrolyte. When you put this together to create an equation for battery discharge, you get Zn + MnO2 + H2O = ZnO + Mn(OH)2. When battery energy is used, negative

What chemistry means to me and how it impacts upon my life From the foods we eat and the medicines we take to the products we regularly use, our lives are inextricably linked to chemicals and their operating principles. Chemistry is everywhere. The air we breathe, the ground we stand on, the seas we sail, and the variety of living things including our own bodies; all these are made of substances that we call chemicals. These chemicals interact with one another, and, in many cases, these interactions

Antitussive drugs are one of the most extended formulations category in the world that use for supperessing cough and cold, for treating the symptoms of a cold or influenza and relief of cough(Allen and Popovich 2005)(Allen and Popovich 2005). Dextromethorphan (DXM).scheme 1.(o-3-methoxy- N-methylmorphinan) is a one of the older and popular antitussive drugs that used to treat the cold symptoms that effects centrally at the cough center to raise the threshold for coughing (Goodman 1990, Dale)(Goodman
