The same slip-and-stick mechanism that leads to earthquakes is at work on the molecular level, where it determines the shear plasticity of nanoscale materials, report scientists. Plasticity is the ability of a material to permanently deform when strained. The researchers, thinking about future things like flexible electronics, decided to see how graphene oxide "paper" would handle shear strain, in which the sheets are pulled by the ends.
