Enhanced Scale Dissolution Using EDTA-2D-Substrate Composite Materials.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In the petroleum industry, barium sulfate and calcium sulfate are among the most persistent and problematic inorganic scales. Their low solubility in water often leads to severe operational challenges, including pipeline blockages and reduced hydrocarbon flow. Therefore, developing effective scale-dissolving materials is essential for maintaining production efficiency and equipment integrity. In this study, newly developed flow assurance materials were introduced that demonstrated excellent performance in dissolving barium and calcium sulfate scales with high efficiency at both low and high temperatures and minimal precipitation tendency. Thermally stable and corrosion-resistant two-dimensional substrates (2D), graphene (CG), boron nitride (BN), and their composite (CG+BN) were immobilized with only 10% of ethylenediaminetetraacetic acid (EDTA) using a simple, single-step synthesis method. These functional 2D-substrate composites effectively dissolved barium/calcium scales separately and simultaneously, outperforming EDTA alone. The results highlight an effective and environmentally benign approach, offering a sustainable and practical alternative for improving flow assurance and mitigating scale-related issues in petroleum operations.
