I’ll leave this part of the notes with an excerpt from a 2017 article in The City University of New York’s Materials magazine, entitled “Graphene-based armor could stop bullets by becoming harder than diamonds.” EXCERPT: While bullet-proof body armor does tend to be thick and heavy, that may no longer be the case if research being conducted at The City University of New York bears fruit. Led by Professor Elisa Riedo, scientists there have determined that two layers of stacked graphene can harden to a diamond-like consistency upon impact. For those who don’t know, graphene is made up of carbon atoms linked together in a honeycomb pattern, and it takes the form of one-atom-thick sheets. Among various other claims to fame, it is the world’s strongest material. Known as diamene, the new material is made up of just two sheets of graphene. It is described as being as light and flexible as foil—in its regular state, that is. When sudden mechanical pressure is applied at room temperature, though, it temporarily becomes harder than bulk diamond.
