Caging Hydrogen in Self-assembling Origami Structures

Let’s say that you’re really good at folding pieces of paper into miniature birds such as cranes, or life-size elephants, something origami artist Sipho Mabona did recently, starting with a 50-foot by 50-foot piece of paper (he had help from up to 40 others).   The paper elephant, including a metal subframe to support it, weighs over 500 pounds. How about using origami to trap hydrogen in a novel approach to storing energy for fuel cells?  Only, instead of paper, you might use sheets of graphene cleverly folded into cages no more than a few nanometers across – the opposite of the elephant in the art gallery.  Researchers at the University of Maryland’s Department of Mechanical Engineering and Maryland NanoCenter, have …
