Hydrocarbon Contamination in Angstrom-scale Channels [PDF]
Nanoscale, 2021,13, 9553-9560, 2021 Nonspecific molecular adsorption like airborne contamination occurs on most surfaces including those of 2D materials and alters their properties. While the surface contamination is studied using a plethora of techniques, the effect of contamination on a confined system such as nanochannels, nanopores leading to their clogging is still lacking.
