Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0

important‚ this being carbon. There are many interesting things about carbon including‚ facts about it‚ its history‚ and what it is used for. Carbon is a very important element‚ in fact‚ life could not exist without it. Carbon (C on the periodic table) is a chemical element and is the sixth most abundant element in the world. Carbon is the 6th element on the periodic table in group 14‚ period 6‚ it has six protons‚ six electrons‚ and six neutrons‚ with an atomic mass of 12.01u. Carbon has a boiling point

Carbon Sink A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration. Public awareness of the significance of CO2 sinks has grown since passage of the Kyoto Protocol‚ which promotes their use as a form of carbon offset. The main natural sinks are: Absorption of carbon dioxide by the oceans

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

April 2014 Radio Isotopic Dating An isotope is an atom of the same element with different number of neutrons. Sometimes the isotope is unstable which causes the isotope to change into a different atom over a certain period of time. By comparing the ratio of the original atom to the product that were in the beginning sample with the ratio of the products at the present time‚ scientists are able to determine the age of a substance. Radio isotopic dating‚ or radioactive dating is the calculation of a

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface

Carbon Dioxide from Cars U.S. states are beginning to attack another major source of global warming pollution besides power plants: your car. David Biello reports Cars in California offer a new kind of sticker shock this year: carbon. In addition to the familiar smog ratings‚ labels on new Cali cars rank them 1 to 10 based on greenhouse gas emissions. The best‚ a perfect 10‚ will emit less than 200 grams of greenhouse gases per mile. The bad ones more than 520. Vermont will also begin offering

A carbon footprint is a way to measure the impact that we have on the environment. The carbon footprint relates to the amount of greenhouse gases that are produced through burning fossil fuels for electricity‚ heating‚ and transportation. There are two sections to the carbon footprint: primary footprint and secondary footprint. The primary footprint is a measure of the emissions of CO2 that we have control over such as the burning of fossil fuels in furnaces and water heaters‚ and for transportation

Carbon Dioxide is a colorless‚ odorless gas that occurs in small quantities in the earth’s atmosphere naturally. The earth’s ocean‚ soil‚ plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a ’linear molecule’. Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to
