“A battery is a device that is able to store electrical energy in the form of chemical energy, and convert that energy into electricity.” ("MIT School of Engineering."). Every battery has an anode, a cathode, and an electrolyte (“How Do Batteries Work?”). The anode is the negative plate, or end, of the battery (“Power System”). And the cathode is the positive plate of the battery (“Power System”). The electrolyte is in-between the anode and cathode and allows the flow of an electrical charge between

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 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

ABSTRACT Microfluidics biochips are revolutionary devices in the field of clinical diagnostics, DNA analysis and molecular biology. Biochips involve various fields of science and engineering i.e., physics, chemistry, biochemistry, nanotechnology, fabrication technology and computer science. It uses small volume fluids on scale of micro to nano liter for automatically carrying out the reactions needed for some biochemical assays. In this report I have covered basic overview of biochips, kinds of biochips

aqueous solution, H6[CoW12O40] molecule dissociates to H+ and [CoW12O40]6- as a strong acid. During the battery charging and discharging process, the cobalt in [CoW12O40]6- is oxidized or reduced reversibly at positive electrode, whereas tungsten is reduced or oxidized at negative electrode. H+ moves through the IEM as the charge carrier. The electrochemical reactions of the RFB are as follows: At anode: CoⅡW12O406- ↔ CoⅢW12O405- + e- φ0= 1.103V vs. SHE (1) At cathode: CoW12O406- + 2e- + 2H+ ↔ H2CoW12O406-

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

being an electrochemical cell that has the ability to turn chemical energy into electrical energy. All batteries contain an anode, cathode, electrolyte and a separator. The difference between distinct types of batteries are the materials used as the electrodes and electrolyte. There are two types of battery categories in which all batteries can fall under, the primary battery which is a single use battery cell and the secondary battery cell which can be recharged and used numerous times.1 Secondary batteries
