Download file to see previous pages the exchange current densityobtained by extrapolation to zero over potential depends on the Tafel-slope value used for extrapolation the author is able to choose his variables. This is because variations in Tafel-slope used forextrapolation could result in large deviations to occur in the intrinsic exchange current density for ORR. The amount of temperature in the oxygen reduction reaction has to be considered since temperatures above 70o C are difficult to operate in.
In this experiment, the set up made sure transport losses are minimum. For that to happen, the H+ was transported through the membrane and electrode whereas oxygen is transported through diffuse medium and electrode this is at an operational workplace of 1o00%RH and pure oxygen. By reducing the cathode platinum loading and the oxygen partial pressure in this experiment, low cell potential is attained.
The experiment was a not a success due to the many inconsistencies in the results. Despite of that, it was able to demonstrate the increased performance of the coverage dependent kinetics could be used instead of constant Tafel-slope kinetics for performance in real life experiments. Details of how that will work are outside the scope of the ...Download file to see next pagesRead More

Comparimg Rigidising Methods Using Reenforced Material
...? Comparing rigidising methods using re enforced material Comparing rigidising methods using re enforced material Introduction A fiber-reinforced polymer (FPR) is a material containing high-strength fibers made of either glass or carbon implanted in a polymer matrix. FPRs are of great benefit in repair and construction works because of their enhanced strength, resistance to corrosion and ability to use with ease as opposed to steel materials. Carbon fibers are the best to use in the reinforcement because they induce higher stiffness, general strength and effective fatigue and durability properties [8]....

...uses: It is known that enzymes enable particular industrial processes to be undertaken at normal pressures and temperatures. As a result of this, the amount of energy needed will be reduced as well as the expensive equipment required (Schnell, 2000). Also enzymes are meant for domestic use .For instance, in 'biological' detergents. Materials and Methods The experiment was carried out in pairs of two and the measurement got was compared with the average of the class measurement. The entire substrate and PH range was used as shown below. It was expected that the reaction to be set up then monitor the reaction with spectrophotometer for 5 minutes upto the point when the...

...? Sustainability Issues of Using Oil and Petroleum Products Sustainability Issues of Using Oil and Petroleum Products Mankind has heavily relied on the natural resource endowment for their daily survival and sustenance. These natural resources and man-made resources have played a critical role in supporting the rapidly growing human population. However, following the rising population pressures on the available resources, these resources are the brink of depletion and exhaustion are they are being consumed by at prodigious rate by the mankind. Some of the natural resources that are highly threatened include trees, wildlife, fertile soil, and fossil fuels. Although some of these resources such as trees,...

Enzyme Kinetics
...ENZYME KINETICS To test how temperature, ph, substrate concentration, and enzyme concentration affect hydrolysis of lactose was theinterest of this research. This was done to learn the structure and function of an enzyme, to learn the relationship between substrates, enzymes, and products, to understand how different factors can affect the rate of an enzymatic reaction, to learn about lactose, lactase, and how to test for the presence of glucose with a Diastix, and to turn in a formal laboratory report. The researcher utilized Lactaid which is an over the counter tablet as a source of enzymes, known to particularly digest protein and pectin. Obviously, the research adopted the experimental method. So,...

... with your example An example of another reaction that can also be used to demonstrate Chemical Kinetics is to determine the rate at which the Phenolphthalein indicator which gives a colorless to pink indication at the end of acid base titrations is allowed to stand for a few more minutes. Though the solution is colored pink in the course of time it returns back to the colorless solution as the phenolphthalein reacts with the OH- ion in a strongly basic solution. A graph of the concentration of phenolphthalein in mol/L Vs Time (sec) can then be plotted which gives us an illustration as to by what factor is the phenolphthalein concentration is falling as a function of time. It is convenient to perform this reaction... as it is...

...the problems associated with the decision of Sam Jones. The first alternative was to use some faster way to communicate with the original owner. The scenario lacks defining the medium used or available to be used by Sam Jones. Hence other options that might be helpful must be considered. The other available alternative was to ‘resign’ clearly explaining the reasons of resignation. The last alternative was to ‘clearly’ explain the boss about the problem and laws that were relevant to the situation and copyrighted material. And if the boss still insists, do as he wanted Sam to do! Evaluating Alternatives: The first alternative as described...

Materials selection using CES material program
...Material Selection Using CES Program Material Selection Using CES (Cost Estimation) Program CES is an important application in the design and manufacture of engineering products. This tool has been used in the selection of materials for the umbrella construction described in this paper. In the selection of proper materials for the umbrella, factors that need careful consideration include its use, functionality and sustainability. Output from the CES program From the program, the umbrella was broken down to individual parts to understand the materials that were needed, and their...

Enzyme kinetics
...Part C Enzyme Inhibitors Enzyme inhibitors are molecules that interact with the enzyme preventing it from working in a typical way. A competitive inhibitor is a compound that resembles the molecular geometry and the chemical structure of the substance. Such inhibitors compete with the substrate molecule for the same site. We can measure the enzyme inhibitor ki through isothermal titration calorimeter. This involves titrating the inhibitor into a solution of enzyme and then measuring the heat released. Another way of measuring inhibitors is through Michaels Menten equation. Here, we need to observe an enzyme activity under a variety of substrates and concentrations. We can then plot the fitting data on graphs using Line...

Evaluate an article
...Evaluation of An Article The Economist Newspaper article is about the effects of cost of production and how the cost of production can influence the profitability of the business and strategies of operating a business. The cost of operating business affects investor opportunities and operating strategies (1). Although a decline in prices of commodities can discourage investors and slow down economic growth, it offers business with an opportunity to explore other alternatives to improve competence. Decline in oil prices causes reduction in the investments of the energy firms. It results to the reduction in production and consequent reduction in energy consumption thus...

Combining and using source material
...research as a learning of an object in order to get new data. Howard and Sharp (1983), in his “Doing Your Research Project”, and Wisker (2008), in his “The Postgraduate Research Handbook”, have a similar view but add that there must be methodological processes which can gain benefit for research. These fairly general definitions are further expanded by Nunan (1994), “Research Methods in Language Learning”, who argues that research must include three elements or components such as 1. a question, problem or hypothesis, 2. data, 3. analysis and interpretation of data. For Wisker what is key is that research has an effect on the world, which is in research results, and finds the realization in our behavior in society. Dawson(2002), however,...
