Recently, some experimental techniques involving bending of cantilevered nanotubes have been used to deduce their elastic bending modulus. Using these methods it was found that the value of elastic bending modulus decreases dramatically from about 1 TPa for D less than 10 nm to 100 GPa for D larger than 20 nm. This discovery defines usual belief that the bending modulus is a material’s intrinsic property,...
