摘要：

Strong intergraphene shear resistance is engineered in multi-walled carbon nanotubes (MWCNTs) by embedding the nanotubes into a compressive-stressing ceramic environment to exploit the exceptional strength of its inner graphene walls during tensile loading. A dramatic enhancement in the tensile failure load of MWCNT is achieved in the ceramic environment and a new "multi-wall" failure mechanism is discovered.
