We disclose novel methods for infiltrating gallium or an alloy thereof into a porous scaffold. Such methods include selecting or providing a porous scaffold; and using a centrifuge to at least partially fill the porous scaffold with gallium or an alloy thereof. The void fraction of the filled-coated scaffold is preferably no more than about 10%. In some embodiments and implementations, the methods further include forming a coating on the porous scaffold to enhance wetting of the scaffold to gallium before infiltration with the centrifuge. With the coating, the void fraction of the filled-coated scaffold may be advantageously reduced to be no more than about 2%. Cleaning step(s) may be further provided to remove oxides from the scaffolds before infiltration with the centrifuge.
