A hybrid means a thing that made of combination of two different elements. Fuhs (2009) states that hybrid car is a combination of gasoline engine with an electrical motor. Gasoline engine is a device that propels work by burning of gasoline inside a chamber. This type of engine is being used in the conventional cars that most of us use today. Meanwhile, an electric motor is a device that produce work by converting electrical energy to kinetic energy. Marriage of these two elements yields a superior

1. How to escape through an emergency door Most of the emergency doors come with a manual override, and can be easily opened with the help of ‘press to exit button’ or with a ‘break glass override device’. In fact, each and every security or access controlled locking system require either a mechanical or electro-mechanical override in order to escape through that particular door in case of an emergency like fire hazard or earthquake. Most of the fire door locks consist of a manual override and

Name: Amra Aliyu Lab partner: Jamie Liang Lab: Empire of Electricity Course: Chem 106 Date: 7/11/2015 INTRODUCTION A galvanic cell is an electrochemical cell that goes through a redox reaction and produces electrical energy . It converts chemical energy to electrical energy and the energy goes from the anode to the cathode. In this lab we had manipulate an exothermic zinc reaction to produce electricity. The same process is used in the making of commercial batteries. A more detailed

DEFINITION AND DESCRIPTION OF THE TASK The researcher will conduct an inflated balloon experiment. This experiment will allow the audience to understand clearly, "Charles' Law" and "Kinetic Molecular Theory" respectively. It will use extremely low and extremely high temperature so that the audience can evaluate the significant difference on the balloon size. The students shall be competent in presenting a laboratory experiment because it is one way to get involve in the lessons taught in school

neuronal signals, my device, specifically the electrode, will be inserted into the rat sciatic nerve to record extracellularly the action potential generated by the neurons. There are several differences between the electrodes and the medium into which they will be inserted. Depending on these differences, there may be an effect on the neural functionality. The first difference to consider is the Young’s modulus of the nerve and the electrode. The electrode, which is made from polysilicon, has a Young’s

The soterix 1X1 tES is capable of having only 1 active electrode, and maximum of 4 return electrodes. By default, tES device and HD-Explore take anode as the active electrode. However, we can choose either anode or cathode as the active electrode, depending on the requirements of experiment. The active electrode should be positioned at location in 10-20 electrode system, which corresponds to the region of interest. Through literature survey we found that P4

dropping-mercury working electrode, which can be used with a staircase or square wave potential technique. Staircase voltammetry applies a potential, holds for a second at the potential and then increases to a higher potential, holding for a second. This is repeated for multiple potential giving a voltammogram that looks like a staircase. This allows an accurate measurement of the faradaic current, which is the current of the redox reaction of the analyte at the electrode, by minimizing the charging

drawbacks and provides high capacitance in small volume [12]. They also have high energy density than conventional capacitors. Supercapacitors are composed of two electrodes immersed in an electrolyte solution. Main difference between supercapacitor and normal capacitor is supercapacitor provides high specific surface area with thinner electrodes as compare to normal capacitors [13]. Thus energy storage in double layer capacitor results from charge separation in thin layers formed between a solid conducting

ECG 10 electrodes are placed on the patient's limbs and on the surface of the chest. The overall magnitude of the heart's electrical potential is then measured from 12 different angles leads and is recorded over a period of time. In this way, the overall magnitude and direction of the heart's electrical depolarization

potentiostat/galvanostat (PGSTAT 101, Eco Chemie, The Netherlands) interfaced with a Nova 1.11 software. A three-electrode system was used in this work consisting of a platinum wire as the auxiliary electrode, an Ag/AgCl/KCl (saturated) as the reference electrode, and a modified carbon paste electrode as the working electrode. A metrohm 827 pH lab (Herisau, Switzerland) supplied with a combination glass-reference electrode was used for pH measurements. 2.2. Materials Acetaminophen powder and TiO2 nanoparticles were

Since then, cosmetics has been part of the routine body care of many people. These products have had an immense improvement and are also a tool for beautification to the human body. Women used cosmetics to make them feel beautiful and confident. But could it also make them sick? Human beings can be exposed to high level exposure to toxins because of the environmental pollutants that we are exposed in thus, humans can have a heavy metal toxicity. Besides the exposure to environmental pollutants,

non-Faradaic reactions. Ion transport and capacitive storage are categorized as non-Faradaic reaction which is standard process that hopefully happen in CDI process, while Faradaic reaction (i.e, redox reactions both on the surface of and within the carbon electrodes) may lead to the formation of chemical byproducts and/or pH fluctuations of the produced water [44], [45]. Faradaic reaction also could lead to instability of long cycle CDI performance, which is specifically caused by reduction reaction at the

particles (ions or electrons) appear in two phases of matter, such as the metallic phase (the electrode) or aqueous phase (the electrolyte). (Lower 2004) These reactions involve the transfer of electric charges between the electrodes and the electrolyte. These cells have two electrodes which are named the anode and the cathode. The anode is the electrode where oxidation occurs and the cathode is the electrode where reduction occurs (Electrochemical cells 2014). Oxidation always occurs simultaneously

internal components. The external component contains a microphone, speech processor and a transmitting coil. The internal component contains the receiver/stimulator and the electrode array. The electrode array consists of electrodes and electrode carrier. The electrode carrier is a wire that extends from the receiver to the electrodes. Working The microphone collects the sound from the environment and converts them into electrical impulses and sends them to

acid. 0.12 M aniline solution can be created by adding 2 ml of aniline and 200 ml of 1 M sulfuric acid. Refrigerated the solution for a night to let the polyaniline solution form nanotube structure. Preparation of Working Electrode. Carbon fiber is used as the conducted electrode for this experiment. Cut two long stripes of carbon fiber into 8 shorter stripes around the same length. The chart shows the length, width and area of each of the eight carbon fiber pieces. To clean the carbon fiber pieces

type of the movement of the eyeand even by the blink of an eye.Here, the Front polar (Fp) and Front (F) are the electrodes which placed near or above the ocular region such that, these electrodes are mainly affected with the ocular artifacts. Considering the eye as the dipole which can state as that front part cornea is more positively charged than the retina. This makes the electrode to become more positively charge than the brain potential when the cornea reached near in the eye movement. Vertical
