A mesh of one-atom-thick graphene foam could become man's best friend in sniffing out explosives.
The Rensselaer Polytechnic Institute announced last week the creation of a graphene material that is 10 times more sensitive when detecting gases than current sensors used by bomb squads. It's also robust and can be made cheaply, according to its inventors.
Using the material to sense ammonia and nitrogen dioxide gases given off by explosive devices could lead to more sensitive and long-lasting tools for bomb detection. It can also be modified for industrial and medical uses in which sensors detect leaks of … Read more
