Silicon dioxide

an aggregate of different minerals or mineraloids. There are over 5,300 known mineral species. The silicate minerals have composed over 90% of the Earth's crust. The diversity and abundance of the mineral species is controlled by the Earth's chemistry. Silicon and oxygen approximately constitute 75% of the Earth's crust, which translates directly into the predominance of the silicate minerals. Our body needs many minerals. These are called essential minerals. Essential minerals are divided up…

Certain gasses, such as Carbon Dioxide (CO2), act like a blanket and trap heat in the atmosphere. These gasses are released into the atmosphere everyday through the burning of fossil fuels. This phenomenon, called the greenhouse effect, is naturally occurring, and is necessary for life on Earth. However, the extreme accumulation of these gasses results in dangerous effects to Earth’s ecosystems and human health. The more greenhouse gasses get burned, the more carbon dioxide there will be in the…

After the catalytic action, carbon dioxide, oxygen, vapor and NOX will remains as the byproduct leading to the exhaust end. This type of catalytic converter is widely used in diesel engines to reduce hydrocarbon (HC) and carbon monoxide (CO) emissions. These are also used on gasoline engines…

The Atlantic Ocean is the second largest ocean out of the five oceans and stretches east of North and South America to west of Europe and Asia. Its climate consists of ocean currents, which are dependent on the uneven heating of the Earth’s surface and continents/landmasses nearby. Ocean currents transport heat energy within the biosphere, with surface ocean currents warming or cooling the air above them, affecting the land nearby. Surface water is affected by wind currents, while deep ocean…

What we are doing about an issue as large as global warming is not enough. We pollute the air to an extreme extent, and we aren’t doing anything about it. The first step in reversing the effects of climate change is to realize how dangerous it truly is. Then, people will realize what our society has to do. Everything we do affects something else- for example, putting too much CO2 into the air causes an increase in temperature, which then causes ice to melt, etc According to NASA, the National…

Although it wasn’t until fairly recently that humans have been severely impacted by climate change, the issue was been present for over a hundred years. The first scientist to conclude that burning fossil fuels in the quantity at which we were doing so would eventually result in elevated mean annual global temperature was Swedish scientist Svante Arrhenius in 1896 (Enzler, 2014). In the early 1900s, other scientists believed that the Earth was experiencing global cooling trends until Stephen…

management approach is performed by the Original Equipment Manufacturers that have direct access and control over the way you take your car to the dealership's service department for repairs. This matrix of materials are usually composed of Cordierite,Silicon,Carbide,or Metal Fibers called a Diesel particulate filter traps the particles flowing out the exhaust pipe. Alternatively, light duty Diesel trucks have very different duty cycles,therefore Ford,GM,and Dodge have all come to market with…

was prepared with different molar ratios, n, ranging from 1 to 4 as shown in Equation (2.1). The result obtained was generally in the ratio of three SiO2 molecules to one molecule of Na2CO3 producing three molecules of sodium silicate and carbon dioxide gas released, shown as equation (2.2). Equation (2.1) n = SiO2 / Na2O Equation (2.2) 3SiO2 +Na2CO3 (3SiO2 , Na2O) + CO2 The result obtained was close to 3.3 : 1 (Brahmi, Merabet et al.…

The cause of climate change, as well as the existence of a major climate change, has been a hotly debated topic over the past decade. While there were many warnings from different members of the scientific community before 2006, nothing seemed to bring more attention to the debate from more walks of life, than the move "An Inconvenient Truth". This movie was so revolutionary that its creator, Al Gore Jr., with the help of the Intergovernmental Panel on Climate Change would win the 2007 Nobel…

Global Warming: Problems and Solutions Global warming is defined as “a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.” by the Oxford Dictionary. This means that due to the effects of pollutants in the atmosphere the temperature of the earth is rising in a process called the greenhouse effect. The greenhouse effect is what happens when solar radiation…
