Talk given by Prof. Hyung Gyu Park Department of Mechanical and Process Engineering ETH Zürich Switzerland Abstract: Fast transport of material along and across nanoscale graphitic surfaces such as carbon nanotubes and graphene, respectively, forms the basis of carbon nanofluidic phenomena for which there are numerous applications in energy and clean technologies. These unique phenomena of nanoscale mass transport has been actively pioneered, and yet still many questions remain unanswered such as “how fast is fast?” This talk begins with an existing paradigm of the fast mass transport phenomena inside carbon nanotubes. Our experimental investigation unravels a new scaling to assess flow enhancements in the nanotubes, which leads to a prediction of equivalence between pores of friction-minimal channels and of channel-less configuration. Size-tailored pores perforated on freestanding graphene bolster the validity of this prediction, highlighting the ultimate permeation that continuous and discontinuous nanoconfinements can provide.
