Skeletal High‐Strength Nanoporous Copper and Metamaterials: The Hakka Tulou Design Heritage

open access: yesAdvanced Materials, EarlyView.
Inspired by the Hakka Tulou walls, skeletal nanoporous copper is fabricated via a two‐phase MnCu precursor and controlled dealloying. This strategy achieves high strength (200 MPa) and large specific surface area (27.6 m2/g), and extends to lattice metamaterials with hierarchical porosity, offering new design pathways for multifunctional metal ...
