Estimation of Nanoporous Au Young's Modulus from Serial Block Face-SEM 3D-Characterisation

Nanoporous Au has been subjected to serial block face-scanning electron microscopy (SBF-SEM) 3D-characterisation. Corresponding sections have been digitalized and used to evaluate the associated mechanical properties. Our investigation demonstrates that the sample is homogeneous and isotropic. The effective Young's modulus estimated by an analytical multiscale approach agrees remarkably well with the values stated in the literature.

Automated summary

Nanoporous Au was characterized in three dimensions through serial block face-scanning electron microscopy (SBF-SEM). The corresponding sections were digitized and used to evaluate the mechanical properties. The study found that the sample was homogeneous and isotropic, and the estimated effective Young's modulus matched well with literature values.
