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

appear to be subsiding any time soon. Mountaintop removal has become an increasingly popular method of coal mining‚ especially in the United States. It is mostly used in the Appalachian Mountains‚ specifically in West Virginia‚ Virginia‚ Kentucky‚ and Tennessee. Coal companies claim this process produces greater economic profit and is safer than previous methods. When the desired site is found‚ the coal companies remove trees and any foliage from the mountaintop. Holes are drilled and explosives
