Methane monooxygenase

Proposed Mechanisms for the Direct Oxidation of Methane to Methanol The oxidation of CH4 usually progresses to C02 and H20 because the intermediates are a series of highly reactive radical reactions and this makes partial oxidation of CH3 into CH3OH very hard. In addition, CH3OH oxidizes faster than CH4 and requires less energy for its oxidation. Industrial attempts to synthesize methanol from methane is usually done indirectly since the direct methods have low methanol specificity and yield. Current

ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy, it doesn’t disappear. We change it from one form of energy into another. A car engine burns gasoline, converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form, but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have

Looking back in the past century in the history of the United States, the nation has experienced a tremendous amount of urban growth with the creation of numerous large mecca cities, interconnected highways and a boom with the ever-changing technology that becomes more available to society. While technology has simplified and helped our nation tremendously, this is just one aspect of the issue of urban sprawl in big cities across America. In recent years, the rapid expansion of metropolitan areas

Global warming extremists want us to believe that as global temperatures rise, so do chances of complete extinction of entire species. Natural disasters will become more common, whole continents could one day be under water, and death rates could be at an all time high. This may seem like a bad science fiction novel, but in some ways they might actually be right. At the very least global warming can and will effect humans living in nearly every region. From those living on the coast, to those living

Investigating the Cause of Global Warming Many people disagree on the issue concerning global warming. Some believe that human activities, various forms of polluting, are the main cause of global warming. Others think that not only have humans not affected the planet by any significant amount, but that not much global warming has even occurred. Many scientists think that pollution is the cause of global warming and the greenhouse effect. There is a lot of evidence to support this theory

Global Warming, also known as the Greenhouse effect, is a problem everyone will soon have to face. The people of the younger generations should be educated about what Global Warming is and that it is caused due to the way people are treating the environment. Planet Earth is estimated to be 4.5 billion years old, and life on earth has existed for more than 3.5 billion years. Humans have been on earth for 2 to 3 million years. It is only been in the past 200 years people have been affected

ACCG399 Case Assignment, Session one, 2013, Quality Equipment Hire Ltd. (QEH)   ACTIVITY 1 – Briefly discuss the 4 different methods of determining Scope 1 Emissions and why the first method is most appropriate for QEH. An organisation should calculate the direct and indirect greenhouse gas emissions resulting from the emissions sources associated with its boundary. Greenhouse gas emissions from scope 1 and scope 2 emissions sources should be calculated in accordance with the methods and guidance

[pic] Besieged by Climate Deniers, A Scientist Decides to Fight Back (A Summary) Ora Major Unit # 1 Written Assignment LS526-02 Professor Brandy Kreisler December 12, 2012 According to reporter and climate scientist, Michael Mann, he and other scientists are being hostilely confronted and unfairly treated because of the results of their research by critics or by those who do not choose to believe or want to accept that climate change or global warming is real and is caused

warming. Studies have indicated a rise in the carbon dioxide levels (CO2) in the earth’s atmosphere that can be attributed to the what is known as the greenhouse affect (Simon, Reece, Dickey, 2007). Natural occurring gases such as carbon dioxide, methane, and water vapor act as source for trapping heat into the atmosphere, however CFC’s or chlorofluorocarbons are man made synthetics (Simon et al., 2007). These synthetic

ANSWER 1: I have noticed that I can make significant reductions to my carbon footprint by making some small changes in the following aspects: a) Heating & Cooling: Insulating and caulking the roof/walls, ventilation and shading/awning can reduce the usage heating and cooling systems, which reduce carbon emissions significantly. Having efficient Energy star rated equipment also helps. b) Refrigeration: Maintaining the freezer (above -15 degrees Celsius) and fridge temperatures (between 3 and 5 degrees
