was done by examining the locations between multiple electrodes connected to a power source of DC electricity. Finding the lines of equal potential difference for two different 2-dimesioanl charge distributions. An equipotential line is a line that has a potential difference equal to zero. Using voltage probes‚ the equipotential lines found were sketched along with the lines that represent the electric field between the electrodes.

Oxidation Reduction Titrations: The Indirect Iodimetric Analysis Ascorbic Acid Unknown Number 69 I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis‚ the oxidizing agent can be determined by a different means than titrating directly with standard iodide‚ because a high concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to

EFFECT OF TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both

ultrasonic waves‚ mechanical vibration or blood flow. Based on arrays of vertically-aligned zinc oxide nanowires that move inside a novel “zig-zag” plate electrode‚ the nanogenerators could provide a new way to power nanoscale devices without batteries or other external power sources. The Nanogenerator is constructed with an electrode lowered on top of the nanowire array‚ leaving just enough space so that a significant number of the nanowires are free to flex within the gaps created by

Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

CHAPTER I Introduction Over 70% of the planet is covered by water. (75% of that is salt water‚ only leaving a 25% as fresh water which can be used for consumption. 70% of the fresh water of our planet is still frozen in the icecaps of Antarctica and Greenland; while the remaining percentage is present as soil moisture‚ or it lies underground as groundwater. Main Problem How can the seawater be utilized for the consumption of different organisms? Sub problems How will the results of the said
