New Technique Makes Light Metallic Nanofoam

Palladium nanofoam

A simple method for manufacturing extremely low-density palladium nanofoams could help advance hydrogen storage technologies, reports a new study from researchers in the UC Davis College of Letters and Science. First introduced about 20 years ago, metallic nanofoams have potential for diverse applications. But before cars can start fueling up via nanofoam, using metallic foams on an industrial scale must overcome challenges including demanding manufacturing conditions, contamination and poor crystallinity.
