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
Just the Two of Us (Will Smith song) number six on the Hot 100 Airplay. It was also a Top 5 hit in the UK, reaching number two. "Just the Two of Us" was one of Smith's biggest solo hits. Smith originally wrote a children's book with the same title and lyrics. For his album, he performed it in rap form. Instrumentation was provided by "Sauce" from the R&B group Somethin' for the People. The song was parodied by Eminem in his infamous track "'97 Bonnie & Clyde" and by Dr. Evil in the 1999 film "". The accompanying music video features Smith playing with his son, Trey,
