Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Freeze-drying removes the solvent directly from the solid phase to the vapor phase through sublimation, which results in an increase in porosity compared to other drying methods.

    “Freeze-drying, commonly known as lyophilization, comprises the removal of the solvent directly from the solid phase to the vapor phase through sublimation, which results in an increase in porosity compared to other drying methods.”
  • Freeze-drying increases porosity and forms a broader distribution of pores from the microscale up to the macroscale, thus improving Pt utilization.

    “This not only increases porosity but also forms a broader distribution of pores from the microscale up to the macroscale, thus improving Pt utilization [214,215].”
  • After freeze-drying, the porosity of the catalytic layer is higher than that obtained by using other drying methods.

    “As shown in Fig. 19, after freeze-drying, the porosity of the catalytic layer is higher than that by using other drying methods.”

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.
