Carbon Nanotube Block - After Compression (image) Rensselaer Polytechnic Institute Caption The same carbon nanotube block after being compressed more than 500,000 times. Even after this stress, there is virtually no difference in the block's shape, mechanical integrity or electrical conductivity. This resistance to wear and tear is similar to the behavior of soft tissues such as a shoulder muscle or a stomach wall.
