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 Emancipation of Mimi that almost every song "showcases Carey's undeniable vocal strengths". Reviewing "Fly Like a Bird", Sinclair concluded, "It's so moving that we'll resist the temptation to be crass and interpret the song as a plea for heightened record sales. Help from above is always welcome, but "Emancipation" sounds like it just might do fine all on its own." Jennifer Vineyard of MTV News considered the album's title to be influenced by Janet Jackson's "Damita Jo", which was also based on an alternate persona. According to Jenson Macey from BBC News, "The Emancipation of Mimi" was Carey's strongest effort from the 2000s;
