Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Hydrophobic DESs are very low viscous solvents even when in contact with water, which facilitates mass transfer between phases.

    “They are incredibly advantageous for water applications as they are very low viscous solvents, even when in contact with water, which facilitates the mass transfer between phases.”

    From Deep eutectic solvents: overcoming 21st century challenges (2019) · cites this paper as [14]

    The Results and discussion section describes the hydrophobic DESs’ viscosities as moderate, ranging from 173 to 783 mPa·s at 25 °C, contrary to the claim that they are very low-viscosity solvents. It reports water content after mixing but does not say that viscosity remains low on contact with water or that low viscosity facilitates mass transfer. The supplied copy gives no page number for these passages. (LLM, conf=0.87)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • DESs have the ability to extract both dissociated and undissociated forms of acidic compounds.

    “These solvents have the ability to extract both dissociated and undissociated forms of acidic compounds [143].”

    From Liquid-phase microextraction of polycyclic aromatic hydrocarbons: A review (2020) · cites this paper as [143]

    In the section labeled “14,15” (page not supplied), the paper says the new hydrophobic DESs “could have” the capability to extract both forms of the acids. The citing sentence presents that tentative possibility as an established ability of DESs generally. The same passage reports the established ability for Aliquat 336, a different extractant. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Most NADES reported in the literature are hydrophilic, while hydrophobic NADES were first reported in 2015 and their utilization is yet to be explored.

    “Most of NADES reported in the literature are hydrophilic, while hydrophobic NADES were reported in the literature for the first time in 2015(van Osch et al. 2015;;Ribeiro et al. 2015) and their utilization is yet to be explored.”

    From The perspectives of natural deep eutectic solvents in agri-food sector (2020) · cites this paper as van Osch et al. 2015

    The Introduction (page unavailable) says DESs are generally hydrophilic and presents hydrophobic DESs for the first time. It does not identify them as natural deep eutectic solvents (NADES). The Conclusions (page unavailable) report their use to extract volatile fatty acids, so the claim that their utilization had yet to be explored is not supported. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hydrophobic NADES made of decanoic acid and various quaternary ammonium salts are efficient for recovery of volatile fatty acids from diluted aqueous solutions.

    “Hydrophobic NADES consisting of decanoic acid and various quaternary ammonium salts were shown to be efficient for the recovery of volatile fatty acids from diluted aqueous solutions (van Osch et al., 2015), although a few years later van Osch et al.”

    From The perspectives of natural deep eutectic solvents in agri-food sector (2020) · cites this paper as van Osch et al., 2015

    The paper’s extraction discussion reports that decanoic-acid/quaternary-ammonium-salt DESs extracted volatile fatty acids from diluted aqueous solutions more efficiently than trioctylamine. The Introduction and Conclusions call them hydrophobic DESs, not natural deep eutectic solvents (NADES), so the “NADES” designation is not supported by our copy. The supplied passages have section labels but no page numbers. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Hydrophobic DESs can be designed to be immiscible with water, so no contamination of the water phase is observed while achieving great efficiency in removal of micropollutants.

    “On top of that, they can be designed to be immiscible with water, and thus, no contamination of the water phase is observed while achieving great efficiency in the removal of micropollutants [13,14].”

    From Deep eutectic solvents: overcoming 21st century challenges (2019) · cites this paper as [14]

    The Introduction describes the developed hydrophobic DESs as water-immiscible, and the Conclusions report efficient extraction of volatile fatty acids. But the Results and discussion report salt leaching into the water phase, contrary to the claim of no contamination. The extraction tests concern volatile fatty acids, not micropollutants. (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
