Mapping the conductivity of graphene with Electrical Resistance Tomography [PDF]

Scientific Reports, 2019
AbstractElectronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene samples, obtained with a dedicated measurement setup and reconstruction software.

Ecohydrologically important subsurface structures in peatlands revealed by ground-penetrating radar and complex conductivity surveys. [PDF]

, 2008
The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow.
