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
Turkish economic boom of the 2000s an economic boom throughout the 2000s. Along with having one of the highest growth rates in the world in the 2000s, Turkey also saw a decrease in unemployment rates, an increase in education rates, and higher life expectancies across the country. Overall, Turkey saw great economic growth throughout the 2000s and this was due to a number of different reasons. In the Spring of 2001, the Turkish government launched a number of macroeconomic policies under the new economic program. These new medium-term policies led to recovery within the country, and ultimately a rise of real GDP beginning in the second
