Received: 18 December 2013; in revised form: 1 August 2014 / Accepted: 4 August 2014 / Published: 8 August 2014 Abstract: An innovative prototype sensor containing A36 carbon steel as a capacitor was explored to monitor early-stage corrosion. The sensor detected the changes of the surface- rather than the bulk- property and morphology of A36 during corrosion. Thus it was more sensitive than the conventional electrical resistance corrosion sensors. After being soaked in an aerated 0.2 M NaCl solution, the sensor’s normalized electrical resistance...

...characterized by the amide group –CONH-as recurring part of their polymer chain. The original nylon was first made in a laboratory in DuPont, USA in 1935 by Wallace Carothers. It was recognized as the first semicrsytalline polymer, the first engineering thermoplastic, and the first synthetic fiber .Amongst various variants of polyamide, polycaprolactam is particularly different in that it is made from only 1 kind of monomer- caprolactam which will be discussed in this paper in further detail from various aspects. Schalak while working on polyamides in IG Fabraen laboratory synthesized polycaprolactam through ring opening polymerization of caprolactom. He heated caprrolactam in a flask to about 250oC with about 5-10% water which hydrolyzed a few percent of the caprolactam to aminocaproic acid. The NH2 group of the aminocaproic acid acted as ring opening initiator for polycaprolactam followed by a polycondensation reaction of the NH2 and COOH group of the low molecular weight product of the ring opening polymerization reaction resulting in a high molecular weight product-Polycaprolactam. The key properties of polycaprolactam that have made them suitable for a variety of industrial applications are toughness, fatigue resistance, oil and abrasion resistance, high melting temperature, excellent fire resistance etc. The distinguishing feature that gives polycaprolactam these combinations of properties are the amide groups which are responsible for the strong hydrogen bonding between the...

...In this project combination of sodium hydroxide and potassium hydroxide is used as electrolytic solution. 1. Caustic soda (NaOH) It is also known as sodium hydroxide, having caustic metallic base. It is hygroscopic readily absorb water as presented in air, so it should be stored in a container. Caustic soda is soluble in water with the liberation of heat along with also dissolves in ethanol and methanol, although it shows lower solubility in these solvents than potassium hydroxide. Molten sodium hydroxide is also a strong base, however high temperature is required to limits applications. Sodium hydroxide solution will leave a yellow stain on fabric in addition to paper. It is used in several industries, mostly as a strong chemical base in the produce of pulp and paper, textile, drinking water, soaps plus detergents in addition to a drain cleaner. Unpolluted sodium hydroxide is a white solid obtainable in the form of pallets; flake granules furthermore as a 50% saturated solution. Properties of sodium hydroxide...

...Electrical Installations K K Sharma Lingaya’s University, Faridabad, Email: krishan_ksharma@yahoo.com Abstract: “Electrical Safety is not an option — it is absolutely necessary for workers and employers alike”. Safety in the workplace is job number one for employer and employee alike. It is especially important for those who install and service electrical systems. Nothing can replace a worker or loved one that has died or suffered the irreparable consequences of an electrical accident. No matter how much an employer tries to safeguard its workers or how much safety training is provided; the ultimate responsibility lies with the worker. The human factor is part of every accident or injury. The purpose of this paper is to identify electrical safety hazards and present ways to minimize or avoid their consequences. It is a guide for improving electrical safety and contains information about governmental regulations, industry-accepted standards and work practices. It presents ways to meet the standards and reduce the hazards. I. Introduction Electricity is very useful and has become essential in modern life. Electric power is used in houses, farms, factories, public places, and commercial establishment and practically in every working place for lighting, operating appliances and machines, heating, cooling, chemical process and transport etc. Electricity is a very good servant but a very dangerous master. Proper precautions will render its...

...185 EQUILIBRIUM 185 UNIT 7 EQUILIBRIUM After studying this unit you will be able to • identify dynamic nature of equilibrium involved in physical and chemical processes; • state the law of equilibrium; • explain characteristics of equilibria involved in physical and chemical processes; • write expressions for equilibrium constants; • establish a relationship between Kp and K c ; • explain various factors that affect the equilibrium state of a reaction; • classify substances as acids or bases according to Arrhenius, Bronsted-Lowry and Lewis concepts; • classify acids and bases as weak or strong in terms of their ionization constants; • explain the dependence of degree of ionization on concentration of the electrolyte and that of the common ion; • describe pH scale for representing hydrogen ion concentration; • explain ionisation of water and its duel role as acid and base; • describe ionic product (Kw ) and pKw for water; • appreciate use of buffer solutions; • calculate solubility product constant. Chemical equilibria are important in numerous biological and environmental processes. For example, equilibria involving O2 molecules and the protein hemoglobin play a crucial role in the transport and delivery of O2 from our lungs to our muscles. Similar equilibria involving CO molecules and hemoglobin account for the toxicity of CO. When a liquid evaporates in a closed container, molecules with relatively higher kinetic energy escape the liquid surface into the vapour...

Dr. Nor Mariah Adam Name Lai Jee Inn Matrik No. GS 42146 INDIVIDUAL ASSIGNMENT Review on How to Improve the Efficiency of the Rechargeable Batteries-Lithium Batteries Lai Jee Inn GS42146 ABSTRACT Batteries are playing important role in our life especially in this high technology era. Laptop, mobile phone, camera and otherwise are using battery to make it to function. In order to improve the efficiency the batteries, several methods are discussed in this paper. INTRODUCTION In this advanced technology era, batteries have been commonly used by the consumers. We use them in different fields like cars, mobile phone, laptop and other else. (Hiroki Kitamura, 2012).Batteries is divided into two main groups which are primary and secondary batteries. (Clean Up Australia, 2009) Primary batteries are the batteries that normally use in dairy life such as remote control, clock but for this kind of batteries is a non rechargeable battery which means that we only can use it for one time and will be throw away after used. This kind of batteries is actually converting the chemical energy to electrical energy and they are normally known as the alkaline batteries. Secondary batteries are batteries that can be rechargeable and recycle after it cannot be recharge. This batteries mostly use for our mobile phone, laptop and other. Although...
