Extended Data Fig. 7: Young’s moduli and Knoop hardness of ND/DMG composite.

(a) Load-displacement curves of ND/DMG composite with an applied load of 1.96 N. The inset shows a SEM image of a typical Berkovich indentation on the surface of Composite-3. (b-d) SEM images of Knoop indentations of Composite-1, 2 and 3, respectively. In all cases, the applied load was 4.9 N.
