Caption

Nanoscale pores are the key to metallic wood's properties, but if there is a crack in the template before nickel is added, it will become an "inverted crack" -- a seam of solid nickel -- when the template is removed. The researchers' technique allows for crack-free regions that are 20,000 times larger than previously possible.
