Utilizing reconstruction achieves ultrastable water electrolysis.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The dissolution of active atoms under operating potential will lead to a decline in their oxygen evolution reaction (OER) performance, thus preventing the current highly active catalysts from being practically applicable in industrial water electrolysis. Here, we propose a sequential leaching strategy to utilize the dynamic restructuring and enhance the chemical bond strength for highly active and stable OER. Modeling on nickel-iron sulfides (NiFe-S), we introduced and utilized foreign Mo dopant preleaching as the sacrificial agent to alleviate the oxidation corrosion of partial M─S bonds. Operando spectroscopic reveal that foreign Mo dopant leach from the matrix and then adsorb on the surface of NiFe O(S)OH as molybdate at lower OER potential. The crystal occupation hamiltonian population analysis uncovers that the charge transfer from molybdate into NiFe O(S)OH will enhance bond energy of M─S, thus preventing further S and Fe/Ni leaching. By manipulating ion leaching, the resulting active phase achieves an ultralow overpotential of 250 mV at 400 mA cm
