The secret of ultralight but stiff sandwich nanotubes

Groningen, Netherlands (SPX) Oct 27, 2021 It is an intuitive rule of thumb: if you reduce the density of a material, its stiffness will also be reduced. But scientists from the Lawrence Livermore National Laboratory in the US noticed that materials that are based on sandwich nanotubes retained their stiffness at lower densities. Modelling by materials scientists from the University of Groningen (The Netherlands) revealed how this
