ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode

Module 16 Notes Reduction/Oxidation Reactions • Oxidation number: The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. • Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though‚ and can help us keep track of electrons during a reaction. • The sum of all oxidation numbers in a molecule must equal the charge of that molecule. • Rules

Objective: DNA is analyzed by agarose gel electrophoresis after being digested with EcoRI restriction endonucleasse. Procedures: λ DNA and puC18 DNA were put into two tubes respectively. Then‚ EcoRI buffer‚ EcoRI enzyme and deionized water would be put into both tubes. EcoRI enzyme was the restriction enzyme that cut the DNA at the specific sequence. The EcoRI buffer enhanced the stability of many enzymes and binds contaminants that may be present in DNA preparations. DI water was used to

Common Types of Capacitors: The compounds or systems that usually consist of two different terminals are used for storing electric power‚ are commonly referred to as capacitors. They form an essential part of any electronic equipment or circuit because they help in the storage of power. The characteristics of the capacitors‚ i.e. the voltage it can withstand‚ material it is made up of etc. are what generally define the ability or the potential of a capacitor. Capacitance is what is generally used

Abstract Chemical reactions can be used to produce electricity and electricity can be used to cause chemical reactions through oxidation-reduction reactions. The first part of the experiment measures the 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
