I. Introduction The world’s current way to produce‚ convert and consume energy comes with a price. Development of sustainable energy technologies which can continue providing the society with energy-derived benefits without further environmental destructions is highly desired. A series of green energy solutions‚ such as solar‚ wind and biomass energy‚ are employed in the hope of preventing the impending global energy crisis (Wang‚ Chem and Huang 2010). Microbial Fuel Cells (MFCs) which capable

Bridgeton should not outsource the manifolds in 1991. Even though ACF took the advice from the consulting firm‚ and outsourced Doors‚ Muffler and Exhausts in 1988‚ their business didn’t get better. (Actually‚ their situation got worse). Their overhead rate in 1988 was 434%‚ and it became 577% in 1989 and 563% in 1990. ACF’s direct labor cost was reduced 46% (from $25‚294 to $13‚537) however‚ ACF’s overhead cost was reduced only 29% (from $109‚890 to $78‚157) This implies that the burden for producing

Electric double-layer capacitor Electrical double-layer capacitors (EDLC) are‚ together with pseudocapacitors‚ part of a new type of electrochemical capacitors[1] called supercapacitors‚ also known as ultracapacitors. Supercapacitors do not have a conventional solid dielectric. The capacitance value of an electrochemical capacitor is determined by two storage principles: Double-layer capacitance – electrostatic storage of the electrical energy achieved by separation of charge in a Helmholtz

Chemistry assignment Introduction: Throughout modern day society metals are constantly used‚ in fact mankind has been heavily dependent on metals for the last several hundred years. But the science behind metals has only been discovered in recent years and has now become known to people that we simply could not live without them. Metals make up around 80% of the elements (currently discovered). They are used in everyday items that society depends on‚ such as: cars‚ re-bars for building‚ window

Core 1 summary notes 1) Fossils fuels provide both energy & raw materials such as ethylene‚ for production of other substances Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚

Experimental Report: Oxidation and Reduction Factors Affecting Electrochemical Cells Research Question: How do the changeable electrodes of different reactivity affect the energy in Volts measured by a Voltmeter while the Solution and the Salt Bridge stay constant for every single trial by the same amount in each beaker? Background Theory: The conductance of an electrolyte depends upon the number of ions present in the solution. Therefore‚ the greater the number of ions in the solution

The Effect of Different Concentrations of the Enzyme Catechol Oxidase on the Rate of Benzoquinone Production When Mixed with Pure Catechol Carson Levine November 4th‚ 2013 Abstract Catechol oxidase is an enzyme that speeds up the oxidation reaction when catechol is exposed to oxygen. When the reaction occurs‚ benzoquinone is produced turning the oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase‚ the browner the
