Mechanical properties of carbon nanotubes 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 sp2 bonds formed between the individual carbon atoms. Although the strength of individual CNT shells is extremely high, weak shear interactions between adjacent shells and tubes lead to significant reduction in the effective strength of multi-walled carbon nanotubes and carbon nanotube bundles down to only a few GPa. Because of their hollow structure and high aspect ratio, they tend to undergo buckling when placed under compressive, torsional, or bending stress. The first transmission electron microscope observation of radial elasticity suggested that even the van der Waals forces can deform two adjacent nanotubes. Young's modulus of on the order of several GPa showed that CNTs are in fact very soft in the radial direction.

A Kdrama where the guy rushing to the hospital to see someone, asks a girl for the directions. In a hurry, she rips out a page of her sketchbook, and writes out the directions to the hospital. On the other side of the page is one of her drawings of a mother and her baby. I think after that he tries to find her to thank her? I am trying to go find movie about young chef that used to own restaurant in a NYC and came to a small town, fell in love with an engaged woman, while struggling to open another restaurant.

The bondage today is particularly brutal. Ashley is flexible as hell, but that doesn't make it any easier. Bent backward over the dresser her arms and legs are pulled to their extremity, so far that her back isn't even touching the top of the furniture.
