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
Inside the Atom did not have adequate science reading material. Inside the Atom Inside the Atom is a popular science book by American author Isaac Asimov. The first edition of the book was published in 1956 by Abelard-Schuman. Revised editions were brought out in subsequent years. The book describes the internal structure of the atom. The sequence of concepts described in the book follows the sequence that those facts were discovered in. It describes the various sub-atomic structures within the atom, and the functions they fill in the whole structure. Later chapters describe chemical elements and isotopes, the stability and instability of atomic
