Pressure-Driven Transport in Tapered Graphene Channels for Energy-Efficient Desalination

Abstract

Nanofluidic Desalination is being reorganized around the joint demands of performance with evidence quality, resource limits, and transfer across settings. This methodological synthesis evaluates how confinement, taper geometry, pressure, and inertial transport shape water-ion separation. The comparison integrates 4 focal papers with 13 independently retrieved publications confirmed at bibliographic registration or publisher level. The analysis is organized around ion exclusion, water permeability, channel geometry, driving force, and scale-up. The synthesis resists treating results from heterogeneous studies as exchangeable, the review compares task scope, modeling premises, and evaluation limits. Across the literature, the literature consistently implies that advances in nanofluidic desalination become credible when structure-property relationships are evaluated together and when uncertainty about operando characterization is reported explicitly. The resulting account aligns method selection to implementation risk, making transfer failures visible, and proposes a research agenda centered on explicit comparators, boundary tests, and reproducible artifacts.
