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 Storm Has Just Begun The Storm Has Just Begun "The Storm Has Just Begun" is a song by country music singer-songwriter Willie Nelson. Nelson wrote the song at the age of twelve. While working for KBOP in Pleasanton, Texas, in 1955, the song was one of the first two ever recorded by Nelson. After two of his demos with the song were rejected, Nelson cut the song during his first session as a recording artist for D Records in Fort Worth, Texas. The song was released as the B-side to "Man With the Blues". It was later covered by Billy Walker the same year.
