1 · What the graph read from it

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.

2 · The registry

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

The hydrogen evolution reaction fundamentally constrains the use of aluminum in acidic electrochemical systems. Existing strategies rely on alloying or interfacial passivation and overlook how the electrolyte controls proton transport (PT) to the metal surface. Here, we demonstrate that the Gutmann donor number (DN) provides a quantitative molecular lever to regulate PT through the aqueous medium and suppress hydrogen evolution corrosion of aluminum. High-DN additives reorganize the electrolyte into compartmentalized domains that disrupt long-range PT and force protons onto tortuous, high-barrier pathways. Using water (DN = 18 kilocalories per mole) as a benchmark, additives exceeding this threshold increase the hydrogen evolution overpotential by ~20 to 70 millivolts at 10 milliamperes per square centimeter and reduce the corrosion current density from 7.44 to 2.23 milliamperes per square centimeter, following an approximately inverse linear dependence on DN. These results establish a direct link between a molecular donor descriptor and mesoscale hydrogen-bond networks, revealing a materials-agnostic strategy for corrosion suppression through targeted control of proton dynamics.
