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
Ever 17: The Out of Infinity represented the various scenarios and moods in the game well, and that it was a big improvement over the music in the previous game in the series. In 2010, "RPGFan" ranked the game as the eighteenth best role-playing game of the 2000s, calling it "a pinnacle of visual novels", citing its story, which they called "one of the most emotionally charged, intense, deep, and compelling storylines ever seen in a video game", and the characters, which they said develop believably, ensuring that the player forms an emotional bond to at least one; they called the character of Tsugumi one of
