portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless battery charger. This wireless battery charger is expected to eliminate all the hassles with today’s battery technology. Wireless power is the transmission of electrical energy

Determination of Percent Potassium & Percent Iron in an Iron Oxalate Salt by Ion Exchange Introduction: This experiment involves determining both the percent potassium (K) and iron (Fe) in a single titration after passing a solution containing a known mass of complex salt through an ion exchange column. Ion Exchange: Certain materials called ion exchange resins consist of rather large molecules which contain ions that can be displaced. The resins are solids‚ insoluble in water‚ usually granular

If too much anhydrous sodium sulfate was added to the solution‚ part of the product would be absorbed too and thus a yield of less than 100% would be produced. 2. Lithium aluminum hydride would also reduce cyclohexanone to cyclohexanol. List three changes that would have to be made to the procedure/conditions to accommodate lithium aluminum hydride‚ instead of sodium borohydride.

Preparation and Ferroelectric Characterization of Calcium doped Barium Titanate ceramics ABSTRACT Barium Titanate (BT) is widely used in electro-optical and electroceramic industry because of its ferroelectric‚ thermoelectric and piezoelectric properties when it assumes the tetragonal structure. In addition to its Lead free composition‚ its perovskite structure allows variation of ionic size and small displacement of atoms that lead to the distortion of the structure which has a profound

AU Section 315 Introduction .01 This section provides guidance on communications between predecessor and successor auditors when a change of auditors is in process or has taken place. It also provides communications guidance when possible misstatements are discovered in financial statements reported on by a predecessor auditor. This section applies whenever an independent auditor is considering accepting an engagement to audit or reaudit (see paragraph .14 of this section) financial statements
