Multiple Negative Differential Resistances in Nanofluidic Conical Pores: A Phenomenological Model.
Article in The journal of physical chemistry letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ionic flow nonlinear effects are helpful for sensing and signal processing in nanofluidic systems. Here, we develop a simple phenomenological model based on a distribution of Boltzmann-like electrical conductances to describe different forms of voltage-controlled negative differential resistance observed in charged conical nanopores. Multiple negative differential resistance phenomena show abrupt drops in the ionic current when the applied voltage exceeds a series of threshold voltages. We use the phenomenological model to describe the multiple states resulting from externally controlled salt precipitation at the conical pore tips. We consider both single- and multipore membranes, together with parallel and antiparallel arrangements of two membranes, as a function of the applied voltage, salt type, ionic concentration, and temperature.
