Scholarcy highlights

  • D Department of Chemistry, School of Natural Sciences, The University of Manchester, Oxford Road, Manchester M13 9PL, UK. Nonspecific molecular adsorption such as airborne contamination occurs on most surfaces including those of 2D materials and alters their properties
  • While surface contamination is studied using a plethora of techniques, the effect of contamination on confined systems such as nanochannels/pores leading to their clogging is still lacking
  • We report a systematic investigation of hydrocarbon adsorption in angstrom slit channels of varying heights
  • Hexane is chosen to mimic the hydrocarbon contamination and the clogging of the Å-channels is evaluated via a helium gas flow measurement
  • We provide a method to assess the cleanliness of nanoporous membranes, which is vital for the practical applications of nanofluidics in various fields such as molecular sensing, separation and power generation
  • This article is part of the themed collection: Nanoscale 2021 Emerging Investigators
