Reframing Nanofluidic Desalination: Measurement Chains and Validation Design

Abstract

Two distinct lines of inquiry—a Bernoulli-effect transport concept for driving water desalination and simulation of tapered channels in multilayer graphene membranes—converge on a practical question for nanofluidic desalination: what evidence is needed before a reported advantage becomes a defensible basis for explanation, comparison, or deployment? A structured reading of two target studies and 12 verified companion references is conducted across five lenses: ion exclusion, water permeability, channel geometry, driving force, scale-up. Emphasis is placed on the provenance of evidence, the comparability of baselines, and the consequences of alternative explanations. Across the evidence base, the decisive issue is alignment: ion exclusion shapes what is observed, water permeability shapes how it is compared, and scale-up governs whether the conclusion can be transferred. Uncertainty is most informative when reported as part of the result rather than treated as a postscript. The resulting framework supports reproducible comparison while preserving differences between study designs, and it identifies concrete points at which transfer claims should be narrowed or retested.
