The nanotubes also had an ultra-low elastic modulus of about 20-30 GPa.

From Science Daily

By measuring lattice distortion as a function of applied stress, the team found that when Sr2RuO4 is compressed by about 0.5%, a measure of mechanical stiffness known as the Young's modulus decreases by about 10%, and then increases by about 20% when the material is compressed further.
