• Ballard Fuel Cell Hydrogen Power Cells
    392 words
    THE BALLARD FUEL CELL The Ballard fuel cell is a power generating device which combines hydrogen (which can be obtained from methanol, natural gas, petroleum) and oxygen without the use of combustion in order to generate electricity. Since fuel cells operate very quietly and efficiently and their only emissions are pure water and heat they are expected to be the future of power generating machines. The PEM fuel cell is made of two plates with a plastic membrane coated with a catalyst in the midd...

    Cryogenics: Is It Worth Waiting For Imagine being frozen in time to escape a deadly illness, then getting warmed when a cure is found. There is question on whether cryogenic methods should be used. To fully understand cryogenics a knowledge of cold, background information on some branches of cryogenics, some problems with cryopreservation, and different peoples views towards cryogenics is needed. "Cold is usually considered hostile to mankind. Most people hate cold and with reasons." If not care...
  • Cell Transformation Resistant Gene

    Title: Colony Transformation Lab Purpose: To study the behavior of Escherichia coli once it has been introduced to a foreign gene. Hypothesis: If the ampicillin resistant DNA is introduced into the E. coli bacteria, through the uptake of this DNA the bacteria will receive the resistant gene that will permit the bacteria to grow freely in the presence of ampicillin. Experimental Design: By observing the E. coli bacteria one can study how it reacts when a foreign gene such as the ampicillin resist...

    Iron Iron in its pure state is soft, malleable and ductile (that can be stretched, drawn or hammered thin without breaking ( (Webster's Dictionary, 419, 1988) ) with a hardness of 4-5. It is easily magnetized at room temperatures and this property disappears when heated above 790 degrees Celsius... Metal iron occurs in a free state in only a few localities, notably Greenland (Encarta, 1996). One of the physical properties of iron as an ore is its color which can be black, brown or even reddish. ...

    Insulation Introduction The experimenter is testing on denim, cotton T-shirt material, wool fabric, thermal underwear, polyester fabric, and a Ziplock bag with no insulator. From research the experimenter learned that wool is a fine soft wavy hair that forms all or part of the protective coat of a sheep. Since ancient times it was harvested to provide clothing and is an important part in textile trade because of its insulation. Woolen fabric is when the woolen system uses short or mixed long and...

    Is there a relationship between the quantity of enzymes and the rate of reaction with the substrate? Hypothesis Using my scientific knowledge my hypothesis is that as the quantity of enzymes increases so will the rate of reaction. Reasons for this hypothesis I am basing my hypothesis on a hypothesis known as the 'lock and key hypothesis.' It explains that when an enzyme substrate complex forms by means of a spontaneous reaction the substrate fits into the active site like a key fits a lock. It i...

    The Effects of Various Factors on the Growth Rate of E. coli Introduction: There are times in our lives (as human beings) when people do not feel well. A doctor might diagnose them with a disease or an infection. There are also times when people do not feel clean. This could be a person's feeling after exercising, sweating, or maybe he / she had not taken a shower in a couple days. In any of the preceding scenarios, bacteria most likely played a major role in initiating a person's feeling of il...

    Imagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimate's. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we wil...

    Aim: My aim is to find out if there is a correlation between the length of the alcohol chain and the amount of energy given off when the alcohol is burnt. Hypothesis: I think that the longer the alcohol chain is, the more energy will be given off. This is because of the previous work we have done in class. We have learnt that the longer the alcohol chain is the more bonds are in the chain. More bonds means more stored energy, energy that will be released when the alcohol is burnt and its bonds b...
