Materials exhibiting gas permeable porosity are of particular interest for a number of functional applications. Here, the authors show a new nanoporous superalloy membrane, far surpassing existing gas permeable porous metals in fineness and regularity of the porosity. This may not only open the path for new medical applications it may also help realizing the vision of miniaturized fuel cells powering laptops and cellular phones.
