The unexpected result started a debate in the community because theory predicted that it would take billions of years for a proton to permeate through graphene’s dense crystalline structure. This had ...

The researchers had previously found that protons easily permeate through graphene’s crystal lattice. However, it remained unknown whether other small ions could pierce the dense crystal lattice in ...

The findings were published in Nature. The Würzburg model system consisting of two nanographene layers that can absorb and bind chloride ions (green) through a defect in the crystal lattice. Image ...

It is particularly interesting for scientists to be able to control the permeability of graphene for different substances. "So-called defects can be created in the carbon lattice of graphene.
