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

  • Lunar regolith-based magnesium oxychloride (MOC) cements are potential candidates for water recovery in space.

    “According to their studies, Lunar regolith-based magnesium oxychloride ( MOC ) cements, which rely on a reaction between MgO and a MgCl 2 solution, are potential candidates for water recovery in space.”
  • On average, MOC paste samples display compressive strength of about 7 MPa, while sintered specimens reach an average of 20 MPa.

    “On average, MOC paste samples display a compressive strength of about 7 MPa , while sintered specimens reach an average of 20 MPa .”
  • This sintering process reduces the volume of permeable pores by 7%, leading to significant increases in compressive strength, particularly when the material is initially predried.

    “This sintering process also reduces the volume of permeable pores by 7 %, leading to significant increases in compressive strength, particularly when the material is initially predried.”
  • Sintering MOC materials at temperatures up to 1200°C results in complete decomposition of Lunar regolith-based MOC cement, releasing HCl and water that could be captured and reused while maintaining material properties standards.

    “Sintering these materials at temperatures up to 1200 ◦ C results in the complete decomposition of the Lunar regolith-based MOC cement, releasing HCl and water that could be captured and reused while maintaining material properties standards.”

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.
