Mechanical properties of carbon nanotubes Mechanical properties of carbon nanotubes The mechanical properties of carbon nanotubes reveal them as one of the strongest materials in nature. Carbon nanotubes (CNTs) are long hollow cylinders of graphene. Although graphene sheets have 2D symmetry, carbon nanotubes by geometry have different properties in axial and radial directions. It has been shown that CNTs are very strong in the axial direction. Young's modulus on the order of and tensile strength of were obtained. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. This strength results from the covalent sp bonds
The Dark Side of the Moo The Dark Side of the Moo The Dark Side of the Moo is an early bootleg recording of the English progressive rock group Pink Floyd, featuring recordings not available on albums released in the US. Unlike other bootlegs containing previously unheard material, the album is made up of recordings that had at least one commercial release. The name is an obvious pun on "The Dark Side of the Moon", the band's most commercially successful album, and the front cover of "Atom Heart Mother", which featured a cow. The album was created by an anonymous label known as "Trixie Records" by
