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 Between the Two of Us Haggard hits like "Sing Me Back Home" and "Branded Man". "Just Between the Two of Us" hit number 4 on the country albums chart. In a retrospective review by Mark Deming for AllMusic, Deming wrote that the album is for "Haggard completists" and notes, "while Bonnie Owens was a good honky tonk singer, she was hardly a great one like Haggard, who seems to be holding himself back a bit musically as he defers to his spouse." Just Between the Two of Us Just Between the Two of Us is a duet album by country singers Merle Haggard and Bonnie
