Deep eutectic solvent assisted oil - water interfacial behavior on polystyrene surfaces: a computational study.
Article in Scientific reports, 2025. 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
Oil-water separation on hydrophobic polymer surfaces, such as polystyrene (PS), faces significant challenges due to poor interfacial control and low wettability. This study computationally explores the efficacy of Deep Eutectic Solvents (DES) as environmentally friendly additives to modify interfacial behavior and enhance compatibility between oil, water, and the polymer surface. Utilizing classical all-atom molecular dynamics (MD) simulations, we investigated the molecular-level interactions and structural organization at the oil-water-DES-PS interface. Our molecular structural analysis reveals that DES preferentially adsorbs onto the PS surface, displacing water and facilitating enhanced contact between octane and PS. Radial Distribution Function (RDF) analysis quantifies this effect, showing a reduction in direct PS-water interactions and a strong, specific affinity between PS carbon atoms and DES choline. Furthermore, interaction energy analysis confirms that DES significantly strengthens the van der Waals attraction between PS and octane, primarily driven by the strong interaction of choline with PS. These molecular insights are crucial for the rational design of advanced, DES-assisted membrane systems, offering a promising avenue for efficient and sustainable oil-water separation.
