Carbon Footprint briefly defined is the amount of CO2 left behind after any human activity. They can be classified into primary and secondary footprints. [ (McLean 2008) ] Primarily‚ it is the direct emission of CO2 from burning fossil fuels or any kind of fuels. They are considered the main and biggest source of CO2 emission‚ thus the having biggest Carbon Footprints. [ (McLean 2008) ] The CO2 emissions from all products and their life-cycles are considered as secondary footprints. The life-cycle

fuels‚ substandard emission techniques‚ and an ever growing population all play an intricate role of raising Earth’s overall temperature. Each can be linked through one key adversary‚ carbon dioxide. Rising CO2 levels are almost the sole reason temperatures are rising at such an alarming rate. Aside from water vapor‚ carbon dioxide is a chief ingredient in our Greenhouse Effect stew. It’s everywhere. It emits from our cars‚ it flies from our smokestacks‚ and it empties from our lungs. All of Earth is

"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

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

Photosynthesis in C3 plants and their adaptations to the Mediterranean Climate Abstract. Photosynthesis is the process that plants use to harness the energy of the sun through light and use it to create sugars. Photophosphorylation is the first step of photosynthesis and occurs in the chloroplast. Light is captured by light harvesting complexes. The light excites electrons which excite surronding electrons through resonance induction and excite special pairs of electrons. These electrons help pump

Carbon Monoxide Carbon monoxide (CO) is a colorless‚ odorless‚ and tasteless gas that is slightly less dense than air. It is toxic to humans and animals when encountered in higher concentrations. Every year‚ at least 430 people die in the U. S. from accidental CO poisoning. It is also produced in normal animal metabolism in low quantities. In the atmosphere‚ it has a role in the formation of ground-level ozone. Carbon monoxide consists of one carbon atom and one oxygen atom‚ connected by a triple

Carbon Footprint Over the next twenty to two hundred years‚ sixty-five to eighty percent of carbon dioxide will be observed into the ocean. This results in affecting the earth over thousands of years after (Carbon Dioxide). Along with this in twenty-twelve‚ eighty-two percent of carbon dioxide was produced from human activities (Calculator). This results in not only harming the world for the next thousand of years‚ but also affects the air we breathe in everyday. In addition‚ the United States average

Carbon Nanotubes Abstract Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology‚ electronics‚ optics‚ and other fields of materials science. They exhibit extraordinary strength and unique electrical properties‚ and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member
