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
On Murder Considered as one of the Fine Arts and a "Postscript" in 1854. These essays have exerted a strong influence on subsequent literary representations of crime and were lauded by such critics as G. K. Chesterton, Wyndham Lewis and George Orwell. De Quincey also refers to the Williams murders in his "On the Knocking at the Gate in "Macbeth"". The 1964 French film "On Murder Considered as One of the Fine Arts" takes its name from the essay. On Murder Considered as one of the Fine Arts "On Murder Considered as one of the Fine Arts" is an essay by Thomas De Quincey first published in 1827 in
