Scientists from Delft University of Technology and the University of Duisburg-Essen have used the motion of graphene to identify noble gasses. These gasses are chemically passive and do not react with other materials, which makes it challenging to detect them.
Graphene’s atomic thickness makes it a perfect filter material for gasses and liquids: graphene by itself it is not permeable, but small perforations make it very permeable. Moreover, the material is among the strongest known and withstands high stresses. Together, these two traits provide the perfect basis for new types of gas sensors.
