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
Children of the Atom still concluded that it was "representative of the kind of thing science fiction does well." Children of the Atom Children of the Atom is a 1953 science fiction novel by American writer Wilmar H. Shiras, which has been listed as one of "The Most Significant SF & Fantasy Books of the Last 50 Years, 1953-2002." The book is a collection and expansion of three earlier stories, the most famous of which is the novella "In Hiding" from 1948, which appeared on several "Best SF" lists. The book's plot focuses on superhuman children with immeasurably high intelligence who have to hide
