water monitoring

Artistic rendering of water sensor with graphene-based nanolayer and two electrodes attached at top. Alternating current voltages at varying frequencies (wavvy lines) are used to rapidly and non-destructively screen for high-quality sensor devices. (Image by Argonne National Laboratory.)
