Abstract Gas transport through nanochannels is ubiquitous in nature and also plays an important role in industry.
The gas flow in this regime can be described by the Knudsen theory, which assumes that molecules diffusely
reflect on the confining walls [1]. However, with the emergence of low dimensional carbon-based materials
such as graphene and carbon nanotubes, it has been evidenced that this assumption might not hold for some
atomically smooth surfaces, resulting in an anomalous enhancement of gas flux [2]. Moreover, in Knudsen
theory, gas molecules are usually treated as mass points and distinguished solely by molecular weight, which
cannot interpret… More >
