Electric Field Mediated Unclogging of Angstrom-Scale Channels.

ABSTRACT: Angstrom-scale fluidic channels offer immense potential for applications in areas such as desalination, molecular sieving, biomolecular sequencing, and dialysis. Inspired by biological ion channels, nano- and angstrom (Å)-scale channels are fabricated that mimic these molecular or atomic-scale dimensions. At the Å-scale, these channels exhibit unique phenomena, including selective ion transport, osmotic energy generation, fast water and gas flows, and neuromorphic ion memory. However, practical utilization of Å-scale channels is often hindered by contamination, which can clog these nanochannels. In this context, a promising technique is introduced here for unclogging 2D channels, particularly those with sub-nanometre dimensions (≈6.8 Å). The voltage-cycling method emerges as an efficient a
