FIG. 1.

(a) 2D x-ray micrograph showing a projection of the tip of the diameter nanoporous gold wire, illustrating the large imaging volume. (b) A small volume was extracted from the 3D reconstruction of the central region of the tip and segmented for morphological and topological analysis.

Image of FIG. 2.
FIG. 2.

(a) Interfacial shape distribution of nanoporous gold with regions corresponding to particular curvatures are shown in (b), (c), and (d). (b) Convex (red online) and concave (blue online) regions; the circle indicates fission pinch-off of a ligament into two knobs, likely due to coarsening. (c) Transition regions with cylindrical curvature (yellow and green online). (d) Regions with zero mean curvature (purple online).

Image of FIG. 3.
FIG. 3.

Surface Normal Distributions for nanoporous gold for projections along (a) the -axis, (b) the -axis, and (c) the -axis (wire direction), illustrating anisotropic spatial orientation of surface patches of nanoporous gold.
